how to see lcd screen in sunlight for sale

What camera do you have? If your camera has an eye level viewfinder, it should work for you outside in sunlight. Optical eye level viewfinders like in DSLR cameras present no problems in sunlight, but electronic eye level viewfinders in mirrorless cameras can be tough to use in bright sunlight, but most work fine. For the lcd on the back of cameras, you can buy a sunshade aparatus that shields the lcd from sunlight and helps, but they are a bit ackward. But first make sure you are using the eye level viewfinder if your camera has one - that"s what its there for.

TRU-Vu High Bright Sunlight Readable Monitors enable users to see clear, sharp video images even in direct sunlight with a bright screen.  Our high brightness screens produce at least 1,000 nits brightness. Some go up to 2,500 nits of brightness.  This makes them far brighter than standard LCD monitors.  Specifically, consumer or commercial-grade monitors typically offer only 150 to 300 nits brightness.  High brightness displays and sunlight readable touch screens will ensure crystal-clear video images even in bright sunlight. The result is better performance and bold colors in other high ambient light conditions as well. They are also available with optical bonding as monitors or touch screen displays.

In outdoor or bright conditions, it is imperative to increase the brightness of a display to ensure crisp images.  The number of nits an LCD display emits is the main factor in determining the monitor’s perceived brightness. A monitor luminance of around 200-350 nits will work well indoors.  Most LCD displays and monitors fall in this range. However, 400-700 nits would be required for use in daylight conditions. Most importantly, a Sunlight readable display requires at least 1,000 nits or more for viewing in direct, bright sunlight . These high brightness displays are available with 16:9 aspect ratio or 4:3 aspect ratio screens.  All TRU-Vu Sunlight Readable monitors and high-brightness touch screens are TAA Compliant.

Some monitors feature a sheet of glass over the LCD panel to protect it from accidental or intentional damage. However, the glass also produces unwanted glare and reflections. Internal reflections in the air gap between the glass and the LCD panel diminish image quality even further. In order to combat this, monitors are optically bonded.

Optical bondingis the process of laminating protective glass or a touch screen panel to the LCD panel with an optical-grade resin.  This completely fills the air gap between the glass and LCD panel. It not only eliminates the internal reflections, but  also increases the contrast ratio. This makes the screen appear much brighter and more viewable in bright light conditions. Optical bonding  also eliminates internal moisture and condensation. Moreover, it will make the monitor more rugged and durable. Lastly, an Anti-Reflective coating is applied to the outside of the glass. Consequently, this will drastically reduce glare and surface reflections.

For installations in indirect sunlight, or reflected bright light, our Daylight Viewable displays will most likely suffice. These are also more cost-effective than Sunlight Readable monitors with 1,000 nits brightness. Daylight viewable monitors feature  LCD screens with 400 nits to 700 nits brightness.  The LCD panels also include optical bonding.

Daylight-viewable touchscreens with optical bonding are also significantly brighter than standard touch screens. Consequently, they produce far better image quality in bright conditions. Although they are not as bright as Sunlight Readable touch screens, daylight readable touch screens do offer the benefit of lower power consumption. This may be useful in portable or mobile applications. We currently offer over 60 monitors with optical bonding; all are TAA-Compliant.

Our outdoor high brightness Sunlight Readable LCD monitors feature waterproof stainless steel enclosures. These are ideal for factory wash-down environments.  Additionally, they are perfect for outside use in challenging weather.  Our panel mount enclosures are made from steel, stainless steel, or aluminum. This enables them to be flush-mounted. Outdoor LCD monitors with high brightness work in a wider range of temperatures. Consequently, this broadens the environments in which they may be used. Additionally, temperature ranges are very important to consider when using outdoors.  When we combine extreme operating temperatures with outdoor waterproof enclosures, we ensure your high brightness monitors will be able to function in even the harshest wet and hot environments. We will also modify or customize any model to meet your exact requirements.

In conclusion, we deploy TRU-Vu outdoor waterproof sunlight readable monitors and high brightness touch screens in a wide range of industries. For example, military, law enforcement, manufacturing plants benefit from high bright LCD displays. Amusement parks, sports stadiums, mass transit, and construction & heavy equipment also rely on high bright sunlight readable displays.  In addition, outdoor high brightness LCD monitors are demanded in pipeline inspection,  kiosks, marine,  oil & gas, drones, security applications. When it counts, you can rely on TRU-Vu Monitors to deliver the optimal weather resistant high bright LCD monitor solution for your specific needs.

I have the same problem, but I think I am going to try something different than what is suggested here. I wear a baseball cap when I am out, just because I have always worn one. I turn the cap backwards when I am shooting. So, what I am going to try is to carry a cloth(handkerchief) in my back pocket. When I want to view the LED, I will flip my hat around and tuck the cloth under the hat so it hangs down. Then, as I lean foward. The cloth should block the sun so I can view the LED and what I am getting ready to shoot. I like the check the histogram prior to taking pictures, so this should allow me to do that on a sunny day. Evan if it doesn"t work or I just don"t like doing it. It wont cost anything.

There are more and more TFT displays used in outdoor applications, such as automobile display, digital signage and kiosks. High ambient light in outdoor environment often causes wash-out image and renders the screen not readable. Readability & sustainability of TFT  display under direct sunlight is becoming vital. Topway Display has been developing sunlight readable LCD display solution for years. The company understands the ins and outs of sunlight readable TFT LCD.

Visibility is the ease with which a viewer can detect an object, or in more scientific term: the relationship between luminance contrast and human eye’s threshold. Therefore, the higher an object’s contrast is, the better is its visibility.

For an LCD to be readable in outdoor environment with very bright ambient light, the LCD screen’s brightness needs to exceed the intensity of light that is reflected from the display surface. To be comfortably viewed by human eyes, the LCD’s brightness needs to exceed its reflected light by a factor of 2.5 at minimum. Naturally, to make an LCD sunlight readable, we can work on two areas, increasing brightness or reducing reflectance.

On a clear day in direct sunlight, the ambient brightness is about 6000 cd/m2. And a typical TFT LCD with touch screen reflects about 14% of ambient light, which is around 840 cd/m2. These days, most LCD displays use LED backlight as light source. It is not too difficult to increase an LCD’s brightness to 800 ~ 1000 Nits, to overpower the bright reflected sunlight. Thus, you have a sunlight readable TFT LCD.

However, this method requires more backlight LEDs and/or higher driving current. The drawbacks are high power consumption, more heat dissipation, increased product size and shorter LED backlight lifespan. Apparently, increasing backlight to make TFT LCD sunlight-readable is not a very good solution.

Transflective TFT LCD is a TFT LCD with both transmissive and reflective characteristics. A partially reflective mirror layer is added between LCD and backlight. This change turns part of the reflected ambient light into LCD’s light source, increasing the TFT display’s brightness. However, transflective TFT LCD is more expensive than transmissive one. At the same time, the partially reflective mirror layer will block some of the backlight, making it not ideal in indoor or low ambient light environment.

What causes light reflection? When light traveling in one transparent medium encounters a boundary with another transparent medium, a portion of the light bounces off the border. Through the simplest version of Fresnel’s equation, we can calculate the amount of reflected light.

The total reflectance on a TFT LCD with touch panel is the sum of reflected light on any interface where two materials meet. As an example, between polarizer and display glass, the difference in index of refractions for the two materials is very small, around 0.1. So the reflected light on this interface is only 0.1%. As Fresnel’s equation points out, we should focus reflection reduction on air interfaces. For air, its index of refraction is 1; for glass, it is 1.5. And that results in a reflectance of 4.5%. Therefore, the three air interfaces contribute majority of TFT LCD’s reflectance, at about 13%.

The quick and easiest thing we can do to reduce air-glass interface reflectance is to use an Anti-Reflection and Anti-Glare film or apply AR coating. An external film with AR properties not only reduces reflected light, but also brings other benefits.

For food industry application, shattered glass is a serious problem. An LCD screen with external film solves this issue nicely. As for automotive applications, in an accident, broken LCD with top AR film won’t produce sharp edge glass that could harms auto occupant. Nevertheless, a top film always reduces TFT LCD’s surface hardness. And it is susceptible to scratches. On the other hand, AR coating retains LCD’s hardness and touch performance. But it comes with a bigger price tag.

Another quick and easy way to tackle reflectance is to affix a linear polarizer on the top of TFT screen. When ambient light gets to the top polarizer, only half of the light passes through. Which results in reflection light cutting to half. This is a very low cost way to increase TFT LCD’s contrast, such that making it more sunlight readable.

Laminating a circular polarizer in TFT LCD will get rid of a lot of reflectance. That is because when ambient light passes through circular polarizer it gets circularly polarized. And when it is reflected, the polarization direction flips by 180 degrees. So when reflected light comes back to the circular polarizer, nothing goes through to viewer’s eyes.

This method is very effective for an LCD display with resistive touch panel. We know resistive touch LCD has two air gaps: air gap between two ITO layers and air gap between touch panel and LCD display. Reflectance caused by the two air gaps is very high. Applying circular polarizer blocks off most of the reflected light, and makes the LCD display sunlight readable.

The disadvantage of such solution is its cost. Since we need not only a circular polarizer, but also a retarder film on the top of LCD display, making sure light originates from within LCD is not blocked by external circular polarizer.

Add AR films on both interfaces of internal air gap. The add-ons can reduce this area’s reflection from 8.5% to 2%. And since the AR films are not outside facing, they are much cheaper than the one used outside. Keeping the air gap also retains the ease of service, in case either touch panel or LCD display needs to be repaired.

The most effective way is to eliminate air gap totally, by using optical bonding. In plain language, we fill air gap with special optical adhesive, to smooth out the area’s refraction index differences. Such that reflectance caused by internal air gap drops from 8.5% to 0.5%. Optical bonding is expensive but effective way to improve TFT LCD sunlight readability. It enhances durability and resistance to impact. Moreover, no air gap means no moisture condensation and fogging.

There are many ways to make TFT LCDsunlight readable. They all have their own pros and cons. With 20+ years" LCD design and manufacturing experience, Topway knows how to create the best sunlight readable TFT LCD for challenging environments. Leave us a message and let"s start the conversation of creating suitable sunlight readable TFT LCD for your project.

Crystalfontz has a large selection of sunlight readable displays. We carry both graphic sunlight readable LCD displays as well as character sunlight readable LCD displays.

A transflective lcd offers lower power for high ambient light applications, very good sunlight readability, and good balance between indoor and outdoor readability. They perform better under all lighting conditions, especially direct sunlight.

A reflective lcd display has polarizers that are basically a mirror that sits behind the LCD glass reflecting all the light from the sun and redirecting it back towards the user. The brighter the light, the easier it is to read. The downside to a reflective polarizer is that in dark environments, you cannot put a backlight behind it. The reflective polarizer will block any light from reaching the user. If you must have a backlight, you may need to add an edge lit or side lit LED light.

If there is a sunlight readable display you"re not finding here, please talk to our support team, they might be able to find one that will fit your needs.

Effects of direct sun-light exposure to Touchscreen equipped Liquid Crystal Display monitors and mitigation techniquesIntroductionLiquid crystal, at room temperature, is neither a liquid nor a solid. This state allows liquid crystal to be usable as a light controlling device – i.e.: Liquid Crystal Display (LCD). However, liquid crystal can be adversely affected by temperature changes causing undesirable results. Low temperature environments can cause the crystal to transition more to a solid thus causing the crystal to be less responsive to changes needed to properly control light. In a LCD this can be observed as slow transition time from frame to frame (choppy video or memory of previous image). Higher temperature environments cause the liquid crystal to transition more to a liquid state, again causing the crystal to not perform correctly when controlling light. This effect can be seen in an LCD as a lowering of contrast ratio (darkening) or in extreme heat conditions melting the crystal resulting in a completely dark LCD image. Direct sun-light exposure typically does not cause LCD to internally heat enough to reach the liquid crystal’s melting point. However, touch monitors have a glass overlay and air barrier on top of the LCD. This can cause a greenhouse effect causing the air temperature between the touch sensor and LCD to become much hotter than the ambient temperature.Preventive measures

Orientation: The easiest way to prevent thermal heating by the sun is of course to not expose the LCD to direct sunlight. In many cases simply orienting the face of the LCD monitor in an East/West position will prevent the greenhouse effect and darkening of the LCD.

Covering or awning: If orientation cannot be controlled and the design allows for it, a simple shade can be employed to block direct sun light. The shade can be a protective awning overhead, or a cover that lies over the screen prompting the user to open or remove the covering to use the device.

Touch Technology choices: Touch sensor design varies based on the given technology. Technologies such as APR and SAW are based on glass only technologies. Resistive and Capacitive technologies have coatings which block some light transmission in both directions. In theory, touch sensors with coatings would slow the greenhouse effect by blocking a percentage of entering light thus slowing the LCD darkening. Touch sensors such as Infra-Red and Optical have no boundaries on the substrates; thus films, coatings or substraight material itself can be adjusted to block additional light.

Films and Coatings: Films designed to block light can be applied to some touchscreen technologies to slow the greenhouse effect. APR, resistive, capacitive, Infra-Red, and Optical all would be candidates for addition of films. The below experiment shows the results of three APR screens with various films and no film applied.

TestingTesting was performed on three Elo ESY15B1-APR products, outdoors in direct sunlight for 4-hours. A white background was displayed and a burn-in was test running to load the processor.

The Elo product with *Nushield, NU204GA Anti-Glare film applied, looked very dim before testing and was difficult to read after 4-hours but the pixels did not melt.

Note: The product with NU405RA film also appeared clearer in normal conditions than the one without a film applied, however the touchscreen was a little more difficult to activate with the shield verses without the shield.

Note: The beginning luminance readings of the product with NU405RA film applied were higher than the no film control. This may explain the appearance of a brighter screen with film applied.

Before answering the questions below, it would be helpful to provide a simple overview of how a TFT LCD works. Every monitor or touchscreen computer includes an LCD panel. The LCD panel is the component that you are viewing at this very moment. This panel includes a thin layer of TFT LCD pixels, where each pixel includes a red, blue, and green rectangle. You can actually see the individual pixels on a display if you place a drop of water on it. The drop will magnify the pixel area and reveal a pixel with a red, blue, and green rectangle. Each red, blue, and green rectangle is a small lens that can be adjusted to allow varying amounts of light to pass through. The colors you see on your screen are determined by how much light is passing through each adjustable red, green, and blue element of each pixel.

The light that you see does not come from the pixels themselves, but from the backlight behind the pixels, which is a series of carefully placed LEDs that emit white light that projects through the LCD pixels. You cannot see the individual backlight LEDs when you look at your monitor, because there is layer of light diffusing material between the LED backlight and the LCD pixel layer. The light diffusing material scatters the light from each individual backlight LED, so they do not show up as bright spots on your monitor.

To summarize, the three layers of an LCD panel are the TFT LCD pixel layer, the diffuser layer, and the LED backlight layer. Note that some LCDs have edge-lit backlighting, but there is no need to go into detail about this, as the same principles apply. That completes LCD panel course 101. Now, what makes a display sunlight readable?

There are two general ways to make an LCD brighter and therefore readable in sunlight. The first and simplest way is to increase the brightness of the backlight. LCD brightness is measured in Nits. Typical LCD panels have a screen brightness between 250 Nits to 450 Nits. LCD brightness of 800 Nits or higher is generally considered sunlight readable, but most sunlight readable displays are 1000 nits. Increasing the brightness of the LCD panel backlight is the most common method of making an LCD panel sunlight readable. Most of Teguar’s industrial panel PCs and touchscreen monitors are available with this type of high brightness LCD.

Another way to make an LCD sunlight readable is to change the diffuser material between the LED backlight and the LCD pixels to a “transflective” material. The transflective material is similar to reflective sunglasses or a one way window, where the shiny side is facing the LCD surface. When transflective material is used, the sunlight entering the LCD panel travels through the pixels, bounces off the transflective material, and is reflected back through the pixels to your eyes. In this case, the sunlight has much less of an impact on viewability than a traditional LCD panel, as the sunlight is reflecting back through the LCD pixels and contributing to the LCD brightness. One drawback of transflective diffuser LCDs is that they don’t allow for as much of the backlight to pass through the diffuser material, so in low light conditions the LCD does not appear as bright. Transflective diffuser LCDs are not as common as high brightness backlight LCDs.

Optical bonding improves viewability of touchscreen PCs in sunlight or other high-bright environments. In a touchscreen computer, the touchscreen sensor and the LCD panel are separate components. The touchscreen is mounted in front of the LCD surface and there is a small air gap between these two components. When sunlight passes through the touchscreen layer, some amount of the light is reflected between the LCD surface and the touchscreen; this reflection reduces LCD viewability.

Optical bonding is a process where a clear adhesive gel is placed between the LCD to the touchscreen. The gel hardens and bonds the touchscreen to the LCD to eliminate the air gap, improving contrast and clarity. Optical bonding is available on many of Teguar’s touchscreen computers and industrial monitors.

The brightness of a sunlight readable display may be overwhelming at night, when there is little or no ambient light. Most industrial computers with sunlight readable LCDs are available with an optional auto-dimming feature. With this feature, an ambient light sensor on the front bezel measures incoming light and adjusts the backlight brightness to match the current light conditions. This is typically a requirement for industrial touchscreen computers that are used in both sunlight and moonlight.

Sunlight also comes with a high amount of UV radiation that can damage the components used in touch screens. PCAP touch screens resist UV damage better than Resistive, but even a PCAP screen must be protected from too much UV exposure. Teguar computers are best suited for environments that provide some level of shade, such as a roof or overhang above the computer, or a structure that blocks the screen from direct exposure to the sun. Most outdoor computer manufactures, Teguar included, will offer a specialized shroud/hood that mounts directly to the unit to provide some level of shade.

Most of our products can handle a few hours of direct sun exposure per day, but full exposure to direct sunlight will cause damage to most touch screens in around 1 year. Contact a knowledgeable Teguar sales rep to discuss the details of your own environment and we can help determine the best solution.

Touchscreen computers in vehicles commonly require high brightness LCDs, because of the ambient sunlight coming through the windows. Sunlight readable LCDs are also used in many indoor applications surrounded by windows, such as air traffic control centers, railroad cars, marine vessels, agriculture machinery, and public kiosks.

I have the same question as Pieter. From the ST7282 datasheet, it is not possible to send any commands or change any registers without using the serial interface, and that serial interface is not provided on the 40-pin flex.

Even if this is true, there are still ST7282 registers that users might want to change. For example, on pages 39-40 of the datasheet, I see registers for setting brightness, contrast, and gamma. These will not be accessible.

Is there a demo of this display to prove that it actually works? Because leaving out the serial interface seems like it might have been a mistake made by the designers. I just want to make sure that this module actually functions.

> Regarding the software part,there is no need to make the setting for any registers as all of them are default value and doesn"t support to change, you just need to make the setting for VSYNC,HSYNC,DCLK Period, DCLK Frequency in your initialization code and you could get the parameters from ST7282 datasheet page 60.

Bottom line: Smartphones and tablets don’t generally work well in bright environments. But there are a couple of things you can do to make them easier to use while outdoors on a hot, sunny day.

Both iOS and Android have a “quick settings” feature to enable it – by swiping up from the bottom on iPhone or swiping down from the top on Android – and you can then slide the brightness bar all the way to the right.

Note: the brighter your backlight, the worse it is on the battery and the more it could cause eye strain, so don’t keep this on all the time. Those who wear polarized sunglasses may have added disadvantage, so play with brightness settings that work best for you.

Alternatively, you can enable “auto brightness” on your device, so that it recognizes the amount of light around you and automatically adjusts the screen brightness accordingly.

Some smartphone users – especially among those who work in the field – like to use an anti-glare cover. Around $10 or so, these small covers physically shield the phone’s screen from sunlight.

Just like when you buy a smartphone case, you’ll likely need to buy one that fits your exact model, though some are adjustable to fit models anywhere from 4.5 to 5.2 inches. Most fold down flat for easy storage, while others are meant to suction to a windshield.

Also, while you’re likely aware of screen protectors meant to reduce the odds of a scratch or crack, some products claim to reduce sunlight glare, too. Starting at about $5 for older models and $10 for newer ones, these “matte” screen protectors stick on top of your existing screen, so you’ll need to buy one that fits your exact phone.

When in direct sunlight, some phone users find it easier to read text – such as emails, text messages, or ebooks — when it’s white words on a black screen. It’s worth a shot, if you haven’t tried it. Enter your phone’s Accessibility settings to reverse the text color. It might be a tab you can touch called White on Black On/Off.

There are other Accessibility settings you may want to experiment with, such as Color Tint and other visual tweaks, along with the option to have text read to you if you’re having trouble reading it in the sun.

And don’t forget: you can dictate messages using your voice – utilizing personal assistants like Siri or Google Assistant – if you’re having trouble seeing the phone’s keyboard. Just be sure to double-check what’s transcribed on the screen before you hit “Send.” (Funny story: I once had a cold and said hi to my friend Mitch in a text message, but the words “Hi Bitch” was typed out and sent. Sigh.)

A few factors contribute to how easy a screen is to read outside, including the type of screen it is (IPS, AMOLED, and so on), and how bright the backlight is (the larger the number of “nits,” the brighter it gets).

That said, you’re not likely to buy a smartphone that’s better to look at outside, but some are better than others. Newer and premium devices typically have higher-quality screens and with higher brightness.

And then there are phones designed to work in harsher environments. These “ruggedized” phones – such as the CAT S60, Sonim XP7, and Kyocera DuraForce — are waterproof and drop/shock-proof, and some advertise its anti-glare screens can also be used with gloves for those who work in the field.

On a related note, if you’re looking at photos or videos you took on your smartphone, never delete unwanted ones from the phone when you’re out. Why? Wait until you see the shot bigger on a computer monitor as it may be better than you think. Plus, deleting media from your phone eats away at the battery. Since you likely have lots of room on your phone, just do it later from home or the hotel room.

When an LCD is used in a high ambient lighting area, outdoors or even in direct sunlight a normal brightness display becomes almost unreadable. Most people have experienced this phenomenon using their mobile phones, tablets, and notebooks outdoors or when sitting near a window on a sunny day. The display looks hazy, dark, and may even have a halo over the screen. As an individual you have the option to turn the hand-held device to shade it from the bright light to read the information. Could you imagine passing at mid-day by a street-side shop with a display showing their products advertising sales items or specials, but the display can’t be read. The customer would not know what messages the shop is trying to deliver. A missed opportunity to make an impression on a potential customer. All the money spent on the advertisement and equipment but did not capture the attention of the customer because the display was too dark. A sunlight readable LCD displays, also known as a high brightness display are designed to operate in an outdoor setting or in direct sunlight. These products are designed to be very rugged and durable to meet the most the challenging environmental conditions. These are a must have requirement when developing industrial displays used in environments such as oil and gas, marine, military, agriculture where a product must perform for long periods of time.

There are several technical approaches and various enhancement methods to increase screen viewability and reliability in the sunlight. The primary enhancement is to develop a backlight system that increases the brightness of the LCD to overcome a brightly lit environment. There are other technologies that can be added to a high bright backlight such as transflective enhancement (Meaning both Transmissive and Reflective) that will use some of the ambient lighting to make the screen more readable in bright environments. Direct backlighting technology now includes local dimming. This feature concentrates the backlight only in an area where the image needs to be bright further increasing contrast of the LCD display. Other enhancement includes the use of Anti-Reflective and Anti-Glare (AR/AG) cover glass that is optically bonded to the LCD front surface to minimize reflective loss and improve contrast of the display.

Sunlight Readable displays is a core competence of Litemax since the company’s inception. Most displays offered from Litemax include at least a 1,000-nit backlight. Litemax proprietary backlight design, internal heat sinking of the LED junction allows their engineering teams to develop a bright backlight while minimizing over all power and internal heat. This is important for displays used outdoors as brightness is one concern, so is heat built up due to thermal loading caused by the sun. Custom backlights can be developed upon request to even higher brightness of 2,000, 2,500 or even 3,000 nits. The high brightness ensures perfect visual readability under any lighting condition. Below is a table that outlines a brightness that would be suitable based on the environment and application.

One of the methods for minimizing backlight heat and improving outdoor viewability is to enhance the LCD with a Transflective (transmissive-reflective) layer This layer allows ambient light to be reflected through the LCD display, re-directing the light to make the LCD viewable in a brightly lit situation. This enhancement improvement is one of the state-of-the-art technologies for high-performance color-reduced power consumption for displays used outdoors.

AOT (Advanced Optical Bonding) is one of Litemax’s many patents. Optical Bonding is an enhancement that improves readability by minimizing reflective surfaces. This combined with index matching the coatings of the cover element to the adhesive layers further reducing internal reflective surfaces to minimize reflective loss creates the brightest, clearest rich images available in an outdoor display product. AOT is the use of an optical-grade adhesive to laminate anti-reflection glass, touch screens, heaters, and EMI shields to the top surface of a display. This method eliminates the air gap between the cover glass and the display enhancing readability in sunlight. The other advantage of optical bonding is to fill in the air gap where moisture can accumulate in high humidity outdoor environments and the display’s ability to resist impact damage improves significantly. As the pioneer in sunlight readable displays, Litemax strives to develop new leading-edge products and processes for use in the most demanding market segments. These enhancements help overcome the challenges our customers face when deploying a display in a rugged outdoor environment.

The elimination of an air gap between the cover glass and the display preventing moisture from entering that could cause fogging on the display"s surface.

Most of the energy that reaches the Earth’s surface comes from the Sun. Solar radiation is in the visible light wavelengths that we can see. The Sun also emits infrared, ultraviolet, and other wavelengths of energy that is invisible. Of the solar energy that reaches the earth, UV wavelengths have the greatest energy. The remaining solar radiation is the longest wavelength, infrared. Most objects radiate infrared energy, which we feel as heat. This heat can be absorbed by a display when it is in direct sun light. This absorption of the external heat is known as solar loading or thermal loading. To combat solar loading Litemax has developed unique materials and process to add as enhancements to minimize the heat that can build up in the LCD from being exposed to direct sun light. One of the technologies is Anti UV/IR Coatings. Using these coating technologies improves the total solar energy rejection from a Litemax display. This can be up to 53% rejection of these invisible solar allowing the LCD to perform in the most demanding locations.

Local dimming technology has been widely popular in mainstream television for years. Litemax has brought the same technology to our large sized industrial-grade outdoor displays. Local dimming dims the LED backlight to optimize the heat and save energy. Litemax also achieves High Dynamic Range (HDR) through local dimming technology to enable the industry’s greatest color contrast in the industry.

The LED-backlit displays boast high-end features, such as lower electromagnetic noise, wide dimming range, and lower power consumption. These backlight systems are developed to output high brightness but also to increase the lifetime of the LED. This design approach and through testing means Litemax backlight systems are one of the most robust designs available in the market. These high bright backlight systems include a Mean Time Between Failures (MTBF) of 100,000 hours. This exceeds typical longevity requirements for industrial-grade applications that require continuous operation and minimal maintenance.

One of the best ways to grow your business and increase brand recognition is through digital marketing. While creating a strong online presence is increasingly important, physical advertising remains an essential part of driving sales. Digital signage seamlessly blends the benefits of dynamic digital content with actual physical advertising. However, the quality of your billboard advertisements, signage, flyers, and messaging can make or break your efforts. This is especially the case when choosingoutdoor digital signage, where sunlight readability is critical. In this article, we’ll discuss how sunlight affects digital signage, what a sunlight readable display is, and how it can benefit your outdoor advertising strategy.

Sunlight readability simply means to what extent a viewer can read a display in high ambient light conditions, such as direct sunlight. When someone tries to view a traditional display in bright sunlight, the brightness of the sun overpowers the display brightness and it becomes unreadable. You’re probably familiar with this phenomenon if you’ve ever tried to read your phone while standing in direct sun – you can hardly see anything! The same goes for larger displays used in outdoor commercial digital signage. If you’re considering advertising outdoors with digital signage, sunlight readability is essential to the success of your efforts.

The liquid crystal layer of LCD displays are “non-emissive”, meaning they don’t produce their own light, but require an external light source to illuminate the display image. Think of an old school slide show or even better, a film strip. The images are located on a film which sits in front of a light. All of the color and content are located on the film (albeit statically) and the bright light shines through the film to show the view whatever family vacation Uncle Joe and Aunt Sally took their RV to that year. The liquid crystal layer is very similar to this, only the images and colors can change. Just as there are different projection methods for slide shows, LCD displays have three illumination methods which can be used to display their content. They are as follows:

1.Transmissive LCD displaysuse a powered backlight to illuminate the display. Their brightness is measured by candela per square meter (cd/m²), which is often referred to as a “nit.” This unit of measurement accounts for both the luminous intensity and the overall area of a given display. Indoor transmissive LCD panels usually measure between 250-450 nits, while outdoor transmissive LCD brightness must measure at least 2000 nits for sunlight readability with most of the best daylight readable displays measuring over 4,000 nits. The energy required to power a 2000-nit backlight is significant and consequently increases operational costs. The brighter backlight also produces a good amount heat, which then costs even more to cool the display and expedites burn out.

2.Reflective LCD displaysrely on ambient light to illuminate the display. Instead of a backlight, a mirror-like layer is installed behind the liquid crystal layer. In this configuration, ambient light passes through the LCD cell from the front and reflects back to the viewer. Reflective LCD brightness is proportional to the sun — the brighter the sunlight shines, the more light is reflected to the viewer. Because of this, the light source of the display no longer competes with the sun (because it technically is one and the same) and this configuration allows for 100% sunlight readability. Furthermore, because reflective LCDs don’t use a backlight,reflective LCD displays are the only LCDtechnology that maximizes sunlight readability with minimal energy cost.

3.Transflective LCD displaysuse a combination of both transmissive and reflective LCD technologies – both a backlight and a reflective layer – hence, the name transflective (transmissive + reflective). The backlight provides enough luminance for visibility in low to medium ambient light, while the reflective layer boosts the display’s visibility in bright ambient light without increasing power consumption. This hybrid option offers the choice of both illumination options but can negatively impact the display’s color saturation, resolution, and/or contrast.

While the upfront costs are a little higher than traditional advertising methods, the benefits of using commercial digital signage is well worth the investment. Digital signage has helped many businesses save on printing costs that are associated with paper signs or menus while also eliminating the wasted time that comes with changing printed signs out. Digital signage offers businesses the convenience of manipulating advertisements remotely and with minimal effort. This can boost your advertising efforts to change quickly with the time of day, season, sales and promotions. Simply put, digital signage can maximize your overall visibility whiledecreasing your overall spending.

By utilizing sunlight readable LCD displays in your outdoor advertising efforts, you’ll create a stronger first impression with your target audience. The improved visibility of the display itself can boost your business sales and build customer loyalty.

Sun Vision Display panels are100% reflective, meaning they have no backlight whatsoever. This makes them an excellent computer monitor solution for people looking to reduce blue light exposure or other common issues reported by people withcomputer-related vision syndromes. It also makes them an incredible solution for advertising in sunny places, where it can be difficult to view other display technologies - all without racking up hefty energy costs.

It can be difficult to read an LCD display under intense sunlight, especially when it does not have adequate sunlight-readability features. People working on this equipment outdoors would have to work hard to make sure that the screen is readable.

Fortunately, technological advancements are underway to resolve technical issues and other problems faced by individuals who regularly use outdoor LCDs. In the meantime, if you are looking for technical fixes that address the lack of sunlight readability in LCD displays or screen panels, keep these solutions in mind.

A simple solution to improve readability in bright outdoor locations is to turn up the brightness to the maximum level. This will help offset the glare produced by the sun’s rays.

Besides cranking up the brightness, you may want to go for optical bonding as your next technical solution. The goal of optical bonding is to shield the external layer of the LCD display from damage. This damage is usually caused by the sun, water, dust, dirt, and other debris. This process consists of laminating the surface layer of the glass to combine with the elements of the LCD inside the display. Afterwards, a bonding agent, such as silicone or urethane, fills the gap between the LCD layer and the glass. This stops potentially dangerous elements from piercing the surface.

Other than safeguarding the internal mechanisms of the LCD device, optical bonding provides better visual clarity for the user by minimizing the amount of glares, reflections, and shadowing caused by the sun.

Apart from making the screen unreadable, sunlight can also cause the temperature of the device to rise quickly. When a device overheats, it causes the solid LCD crystals to melt. This results in the screen to turn black and become unusable until the crystals cool down and harden again. Thus, it is crucial to install a properly designed ventilation structure in these outdoor devices.

Besides ventilation, mounting an outdoor LCD displays requires protection against the sun. Sunlight contains ultraviolet (UV) rays. Prolonged and excessive exposure to these rays can damage the LCD device. It can affect the display to the extent where it will decrease the readability, which is why it is vital to apply a high-quality protective film. Doing so preserves the lifetime and sustainability of the LCD device.

On top of UV protection, you should also protect an LCD display with an infrared protective film. Infrared light beams give off heat. An LCD display not adequately shielded with infrared could cause the device to overheat and cause damage to the display. Having a working anti-infrared solution will protect the device and improve sunlight readability.

The surface treatment could reduce reflectance on the screen surface. the display are made by many materials layers, such as a Sunlight readable tft lcd display with capacitive touch, from the top layer to bottom layer,it is made by top cover lens --> touch sensors layer-->OCA layer or air gap layer --> top polarizer --> top glass --> bottom glass-->bottom polarizer-->backlight films.

when the ambient light go through the display, the refraction and reflection happened in each layer. the refraction and reflection light combine to diffuse lights inside the display, it lead to display blur to the screen, the situation would be worse under the sunlight that with strong incident light to the screen.

and Anti-Glare film or apply AR coating. it could reduce 2%~3% surface reflectance on the top surface of sunlight readable display. the surfact treatment could be made by additional materials coating on the screen"s surface or an external film on the screen.

An additional linear polarizer on the top of tft screen would also decrease the surface reflectance from ambient light.Or a circular polarizer (O-film) to block reflected light. when

to viewer’s eyes.But the additional polarizers would make the more thickness to the screen, and reducing the brightness of the lcd screen, a surface coating with AR or AG treatment are more effective and popular for the sunlight readable lcd display.

The brightness will be reduced if the module require touch panel or O-Film on it). meanwhile,high brightness displays will generate more heat and use more power than a traditional LCD.

causing worse sunlight readability. We can improve it from two directions.Add AR films or AR surface treatment on both interfaces of internal air gap. it could reduce thereflection ratio from 8.5% to 2%.

Traditional LED display can be in higher brightness when in outdoor working, but common LED screen is hard to make with high resolution(PPI). so it is hard to get a high quality display effect. To the OLED display, even the organic led display(OLED) can be in high resolution, but its cost is more expensive than lcd display. in the same time, LCD"s lifetime is more longer than oled display.

Monochrome lcd display can be used forsunlight readable screen, Its display modes have TN or stn lcd with Positive mode,they are withdark display letters on lighter background. the sunlihgt readable lcd can be reflective or transreflective display mode, the costs are similar for monochrome reflective lcd, transflective lcd, andtransmissive lcd, Transflective or reflective monochrome lcd are the common and economy solution for sunlight readable lcd displays.Since the reflective lcd and transflective lcd has the lowest power consumption than other sunlight readable display, reflective lcd doesn"t need backlight, while transflective lcd only need the backlight in dark environment. the monochrome lcd is easily to custom make, its tooling cost is also cheaper than other custom tft display or oled display.

For lcd displays in daylight and outdoor application, if you"d like color displays, we would suggest sunlight readable tft displays, because the cost of sunlight readable tft is lower than color OLED display, the color tft displays have longer lifetime than OLED display. Different to traditional monochrome lcd, tft lcd screen have full display colors, the high brightness TFT and transflective tft lcd display would be good solutions for sunlight readable outdoor display,
