tft display benefits manufacturer

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) we are talking here is TN (Twisted Nematic) type TFT displays which is align with the term in the TV and computer market. Now, TFT displays have taken over the majority of low-end color display market. They have wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, consumer electronic products etc. For more information about TFT displays, please visit our knowledge base.

Talking about Pros and Cons of TFT displays, we need to clarify which display they are compared to. To some displays, TFT displays might have advantages, but compared with another display, the same character might become the disadvantages of TFT displays. We will try our best to make clear as below.

Less Energy Consumption: Compared with CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) and LED (Light Emitting Diode) display, which made laptop possible.

Excellent physical design. TFT displays are very easy to design and integrated with other components, such as resistive and capacitive touch panels (RTP, CTP, PCAP) etc.

Minimum Eye Strain: Because TFT panel itself doesn’t emit light itself like CRT, LED, VFD. The light source is LED backlight which is filtered well with the TFT glass in front for the blue light.

More Energy Consumption: Compared with monochrome displays and OLED (PMOLED and AMOLED) display, which makes TFT displays less attractive in wearable device.

Poor response time and viewing angle: Compared with IPS LCD displays, AMOLED displays and recent micro-LED display. TFT displays still need to note viewing angle of 6 o’clock or 12 o’clock in the datasheet and still have the gray scale inversion issue.

High tooling cost: Depending on which generation production line to produce and also depending on its size. Building a TFT display fab normally need billions of dollars. For a big size display which needs high generation production line to produce. The NRE cost can be millions dollars.

Sunlight Readability: Because it is very expensive to produce transflective TFT LCD displays, in order to be readable under the sunlight, very bright LED backlight (> 1,000 nits) has to be used. The power needed is high and also need to deal with heat management. If used together with touch panel, expensive optical bonding (OCA or OCR) and surface treatment (AR, AF) technologies have to be used.

Because every point on the TFT LCD screen maintains that color and brightness after receiving the signal, it glows at a constant rate, rather than constantly refreshing the bright spots as the cathode ray tube display (CRT) does. As a result, the TFT LCD is of high quality and does not flicker, reducing eye fatigue to a very low level.

For displays of the same size, the visual area of the TFT LCD screen is larger. The visible area of the TFT LCD is the same as its diagonal size. Cathode ray tube display screen picture tube front panel around an inch or so of the border can not be used for display.

The original LCD screen is usually used in electronic watches and calculators because it is unable to display delicate characters. With the continuous development and progress of liquid crystal display technology, character display begins to be exquisite, but also supports the basic color display, and gradually used in liquid crystal TV, camera liquid crystal display.

The subsequent DSTN and TFT were widely made into liquid crystal display devices in computers, and DSTN LCD screens were used in early notebooks. TFT is used not only on laptops (most laptops now use TFT displays), but also on mainstream desktop displays.

The display material of the traditional display screen is phosphor, which is shown by the impact of the electron beam on the phosphor. The electron beam produces strong electromagnetic radiation in the moment it hits the phosphor. Although there are many display products in dealing with the radiation problem more effectively, as far as possible to reduce the amount of radiation to a very low, but to completely eliminate it is difficult. Relatively speaking, the TFT LCD screen has an innate advantage in preventing radiation because it does not exist at all.

In the aspect of electromagnetic wave prevention, TFT LCD screen also has its own unique advantages. It uses strict sealing technology to seal a small number of electromagnetic waves from the driving circuit in the display, while ordinary displays in order to emit heat. The internal circuit must be in contact with the air as much as possible so that the electromagnetic waves generated by the internal circuit "leak" outward in large quantities.

TFT LCD screens are digital and do not use analog interfaces like cathode ray tube color displays. In other words, with the TFT LCD, the graphics card no longer needs to convert the digital signal into an analog signal and output it as usual. In theory, this would make the color more accurate and perfect.

A traditional cathode ray tube display is always dragged behind a bulky ray tube. The TFT LCD breaks through this limit and gives a whole new feel. The traditional display screen emits electron beam to the screen, so the neck of the picture tube can not be very short, when the screen increases, it is necessary to increase the size of the whole display.

On the other hand, the TFT LCD screen controls the liquid crystal molecular state through the electrode on the display screen to achieve the display purpose. Even if the screen is enlarged, its volume will not increase in direct proportion, and its weight is much lighter than the traditional display with the same display area.

Compared with the traditional display screen, the TFT LCD screen starts with a pure flat glass panel, and its display effect is flat at right angles, giving people a refreshing feeling. And it is easier for LCD to achieve high resolution on a small screen. For example, a 17-inch LCD can achieve a good resolution of 1280 × 1024. On the other hand, the effect of using a resolution of more than 1280 × 1024 on an 18-inch CRT color display is not entirely satisfactory.

The traditional display screen is composed of many circuits. When these circuits drive the cathode ray picture tube, they need to consume a lot of power, and with the continuous increase of the volume, the power consumed by the internal circuit will certainly increase. In contrast, the power consumption of TFT LCD is mainly consumed by its internal electrode and driver IC, so the power consumption is much smaller than that of traditional display.

Whether outdoor or indoor, more and more TFT displays are now presented to us. The display screen is the most critical interface connecting humans and machines. It was originally based on picture tubes. With the improvement of the overall level of display technology, people"s requirements for the display screen are getting higher and higher. Various display technologies are also changing day by day. The longest and most influential one is the LCD screen. Its advantages such as thin and light appearance, no radiation, low energy consumption, and good display effect have occupied the mainstream position of the display screen. People want to know the tft monitor advantages and disadvantages. Next, I will introduce the main advantages of TFT display.

Because every point of the TFT display screen keeps the color and brightness after receiving the signal, and emits constant light, unlike the cathode ray tube display (CRT) that needs to constantly refresh the bright spot. Therefore, the LCD panel TFT has high image quality and will never flicker, minimizing eye fatigue.

The traditional display screen is composed of many circuits. When these circuits drive the cathode-ray picture tube to work, they need to consume a lot of power, and as the volume increases, the power consumed by the internal circuit will definitely increase. In contrast, the power consumption of the TFT liquid crystal display screen is mainly consumed on its internal electrodes and driver IC, so the power consumption is much smaller than that of traditional displays.

Compared with traditional display screens, the LCD panel TFT uses a purely flat glass plate from the beginning, and the display effect is flat and right-angled, giving people a refreshing feeling. Moreover, LCD monitors are easier to achieve high resolution on small screens. For example, a 17-inch LCD monitor can achieve a resolution of 1280×1024, while a 18-inch CRT color display usually uses a resolution of 1280×1024 or more which is not completely satisfactory.

When you are looking for a small gadget display with impressive quality, you really can’t do any better than a TFT LCD display. It’s versatile, reliable, and most of all, impressive.

TFT LCD displays refer to the Thin Film Transistor type of LCD display. That means each pixel in a TFT LCD would have its own transistor glass. This, in turn, offers more control over both the colors and images that it would render. This kind of display has been quite dependable that laptop manufacturers have decided to utilize this for their screens. Soon, TFT LCD displays were also used in television screens.

That said, you don’t have to be a laptop or television screen manufacturer to appreciate the benefits of utilizing these TFT LCD displays. Just to give you a better idea, here are 5 advantages you can expect to gain when you use them to create your own tech gadgets:

Because TFT LCD displays have a compact form as well as an incredibly low depth, they are quite easy to install. In fact, they can even be hung on the wall without much effort. That would come in useful if you are creating a screen for presentations in the workplace or if you simply want to create a dynamic picture frame.

TFT LCD displays are known for displaying crystal clear images. That means consumers are going to enjoy viewing their high quality photos and videos when displayed on a screen made with this. The ability to view high resolution videos and photos are important in the film and television industry, and advertising industry.

Perhaps, one of the best qualities of a TFT LCD display is that it is touchscreen capable. This means that this type of display works great if you are looking to build something that requires accessing an interface on the screen, whether it’s for the regular consumer market or the business to business segment.

Because of its high quality display and touch screen capability, TFT LCD displays enjoy a wide range of use. In fact, it is recommended for television, computer monitors and even the navigation system within an airplane cockpit. At the same time, this display can also be used on handy gadgets like mobile phones, MP3 players, tablets, kindles and more.

One of the best things about TFT LCD displays for small gadgets is that it comes in a wide range of sizes and resolutions. In fact, you can get it in a size as small as 3.5 inches with a display resolution of 320 x 240. In case you require a size not normally offered, you can always order a TFT LCD display in custom sizes.

For all these reasons, it’s smart to consider using TFT LCD displays. Make your tech creation come to life and give it that touchscreen capability that everyone appreciates today. Make sure it stands out by using a TFT LCD type of display.

The worlds of high-end Color LCD Modules are taken over. As our world evolved and embedded devices becoming more, and more sophisticated and prevalent, we tend to look at the art of design. Steve Jobs sums it up just right. “Design is not just what it looks like and feels like. Design is how it works.” TFT LCD modules are a type of variant of an LCD which uses thin film, appliances such as: TV, computer monitors, kindles, mobile phone, and navigation system. The construction of a color LCD module or TFT LCD is quite extraordinary because of the circuit layout process; this form of layout is similar to the layout of a semiconductor product. Even though as we observe the TFT LCD display we came across few pros and cons which are most needed for this discussion. The advantages of TFT LCD are as follows: less energy consumption, visibility is sharper in other words has superb quality, physical design, response time, and less eye strain etc… With every great product there are few disadvantages associated, such as, cost and viewing angles.

TFT LCD displays are very convenient because of the energy consumption associate with this display, knowingly in today’s society saving energy is a number one priority to reduce greenhouse gas and ensure a better future generations. Due to the construction of TFT structures Pixel like materials does not consume much energy to begin with except this material consume far less power than a comparable CRT monitor. The images of a TFT display does not rely on the scanning of electron beams instead they are free from flicker and has a crisp image, with no geometric distortion. The physical design of TFT display are space savors which can be position anywhere in ones office, or house with a rotations mechanism in place for less constrains on space.

As mention before TFT LCD has few disadvantages, due to the nature of the design TFT LCD display may cost a little more than a regular monochrome display. Other disadvantages may arise when the viewing the display at the 6 0’clock direction but in fact the optimal viewing is at the 12’oclock direction this may also lead to inversion which or common in situation like this; however TFT displays are superior and will be in production for years to come.

TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

The use of high brightness displays has risen in popularity over the years. Thanks to their high-resolution image and use in nearly any type of device, they have become versatile and useful in many industries. Thin-film-transistor liquid-crystal display (TFT) displays are perfect for TVs, tablets, video game devices, phones, touch screens displays, and other similar devices.

Combined with high brightness tech, these types of screens have become commonplace. High brightness monitors ensure that sunlight and other sources of light do not affect the screen’s visibility. They remain clear and crisp in all environments. Any business interested in utilizing devices with a sunlight readable screen can benefit from this display. It offers complete and clear visibility that most other screens cannot. The displays continue to work over long periods without any dulling or issues damaging the screen. This allows for regular, even heavy use of any type of device that has this display type.

TFT displays are for flat panel displays, like those on handheld devices and televisions. TFT offers a higher quality resolution. This type of display has better contrast and resolution than alternatives, creating a crisp and clean image.

Thanks to their higher quality images, these have become a standard in many industries, including computing, manufacturing and low-light environments. Beyond the better resolution, TFT also offers better reaction and speed. Everything appears fluid without causing lag or viewing difficulties. When you add high brightness to the mix, it becomes far more valuable.

Because of competitive pricing and short production cycles, most consumer displays do not offer the durability or reliability required in industrial environments. The consumer display life cycles tend to be much shorter when compared to industrial applications. Displays manufactured for consumer usage generally are designed to last for a couple of years with moderate usage.

On the other hand, industrial thin-film-transistor liquid-crystal displays demand longer life cycles. Additionally, when an industrial display is not continued by a manufacturer, the replacement product has to be reverse-compatible and work within the existing environment. A high brightness TFT display can give any device a boost in performance and appeal. These displays are available in a variety of sizes and are ready to go. If your industry requires a high brightness display contact Faytech North America today to speak with one of our specialists today.

The two buzzwords the tech world has been chatting about for a number of years now is IPS, (In-Plane Switching) screen technology used for liquid crystal displays or LCD’s for short, and TFT (Thin-Film-Transistor) an active matrix screen technology, which is more expensive, but a sharper image.

TFT (Thin-Film-Transistor) Liquid Crystal Display is a thin display type, where a transistor embedded into each crystal gate; these transistors are then printed on thin-transparent film. The technology was designed to improve image qualities, such as contrast and addressability.

Also designed in the late 1980’s, TFT display technologies is just another variation of LCD displays that offer greater color, contrast, and response times as opposed to available passive matrix LCD’s. One of the primary differences between IPS and TFT display technologies is the cost. IPS is more expensive than TN technology. However, there are some key differences between the two that should be noted.

Before we go into the differences, let’s talk about features of each technology. Note that we’re not talking TVs, computer, or tablets, but screens on a much smaller scale, (think 7” or smaller) which uses different rules to fit that scale. First, it’s interesting to discover that the TFT display technologies is the most common type of color display technology; more monochrome displays still out-sell color, due to lower cost and lower power consumption, however, the narrow poor visibility of TFTs in direct sunlight is their downside; but I’m getting ahead of myself here.

Brilliant color image – this is a huge advance in technology, from a Twisted Nematic (TN) display that only produced 6-bit color, to an 8-bit color display with the IPS technology

TFT display technologies have developed over the years and have become quite popular in tech circles. The features offered with this advancing technology are:Superior color display – for technology that requires it or for consumers that desire color screens

Features a longer half-life, (half-life is the amount of time in hours before the display is 50% as bright as when it was first turned on), than OLEDs and comes in varying sizes, from under an inch up to over 15 inches

Variety of displays, which can be interfaced through a variety of bus types, including 18 and 24 bit for red/green/blue, LVDS, and 8 bit and 16 bit for a CPU – many controllers allow for two or more different types of interfaces on the same TFT screen

Let me explain. As you can see, both have excellent color display and clarity; however, IPS screens offer greater color reproduction and viewing angles because of the way crystal orientation and polarizers are arranged. In a TFT screen, the structure of the crystals results in angular retardation in the light. The IPS screens thus offer less distortion properties. Other differences include power consumption and cost. With IPS screens, it takes more power (up to 15% more) than with a TFT screen. If you’re on a monitor, such as a computer screen that’s bigger than 7 inches, it will drain your battery faster than if you’re on a 3.5” screen. Regarding cost, IPS panels are more expensive to produce than TFT panels.

The color channels increase from 6 bits (TN displays) to 8 bits (IPS displays) to ensure the precision of shades per color channel, thus increasing manufacturing costs

If you want the benefits of having a Smartphone without a huge price tag, then TFT devices are your best bet. Another difference is that IPS screens have longer response times than TFT screens, so the lag output is greater. A few other key differences to be aware of are that with IPS panels, you get a bigger variety of panels, as was discussed above, with their super, advanced, and so forth developments, giving the consumer options, and IPS screens that can display 24-bit TrueColor; they also stay color-accurate and remain stable.

Now we will go over the downside of IPS screens, which we briefly touched on above, which includes a major disadvantage: cost. If you’re just looking for an average Smartphone or don’t need all the fancy coloring and clarity for LCD displays, then cost may not be a big factor; however, this is the main reason why IPS technology is beginning to come down. As with every new invention, discovery or technology, demand is everything. Another disadvantage is that colors may not always transcribe correctly or accurately, which may or may not be a deterrent. Also, high resolutions are not always readily available for personal applications. In certain circumstances, the brightness may not be enough, especially in darkness.

Steve Jobs said it best: “Design is not just what it looks like and feels like. Design is how it works.” I tend to agree with him. With TFT display technologies, less energy consumption is a big deal, especially when dealing with bigger screens, and of course less electricity means lower cost, overall. The visibility is sharper, meaning no geometric distortion, which is great for these tired, old eyes. The response time and physical design of the screens are also appealing. TFT displays can also save space and be placed virtually anywhere in an office or home, because of the brightly lit feature and crisp clear images.

Some cons of TFT screens deal with the viewing angle, which create distortion, resulting in a less-than-perfect image. Static resolution, meaning the resolution can’t be changed, may also cause a problem, but newer models seem to have tackled that issue. The accuracy of the display of colors is not perfect, specifically strong blacks and bright whites, so when printing an image, it may not display the spectrum of colors.

And there you have it. In the future, even this superb technology will change and new, more exciting technology will take its place. But until then, IPS & TFT screens are forging ahead with their own advances and improvements, so stayed tune. You don’t want to miss it.

Technology trends in backplane technology are driving higher gas demand in display manufacturing. Specific gas requirements of process blocks are discussed, and various supply modes are reviewed.

Since its initial communalization in the 1990s, active matrix thin-film-transistor (TFT) displays have become an essential and indispensable part of modern living. They are much more than just televisions and smartphones; they are the primary communication and information portals for our day-to- day life: watches (wearables), appliances, advertising, signage, automobiles and more.

There are many similarities in the display TFT manufacturing and semiconductor device manufacturing such as the process steps (deposition, etch, cleaning, and doping), the type of gases used in these steps, and the fact that both display and semiconductor manufacturing both heavily use gases.

However, there are technology drivers and manufacturing challenges that differentiate the two. For semiconductor device manufacturing, there are technology limitations in making the device increasingly smaller. For display manufacturing, the challenge is primarily maintaining the uniformity of glass as consumers drive the demand for larger and thinner displays.

While semiconductor wafer size has maxed because of the challenges of making smaller features uniformly across the surface of the wafer, the size of the display mother glass has grown from 0.1m x 0.1m with 1.1mm thickness to 3m x 3m with 0.5mm thickness over the past 20 years due to consumer demands for larger, lighter, and more cost-effective devices.

As the display mother glass area gets bigger and bigger,so does the equipment used in the display manufacturing process and the volume of gases required. In addition, the consumer’s desire for a better viewing experience such as more vivid color, higher resolution, and lower power consumption has also driven display manufacturers to develop and commercialize active matrix organic light emitting displays (AMOLED).

In general, there are two types of displays in the market today: active matrix liquid crystal display (AMLCD) and AMOLED. In its simplicity, the fundamental components required to make up the display are the same for AMLCD and AMOLED. There are four layers of a display device (FIGURE 1): a light source, switches that are the thin-film-transistor and where the gases are mainly used, a shutter to control the color selection, and the RGB (red, green, blue) color filter.

The thin-film-transistors used for display are 2D transitional transistors, which are similar to bulk CMOS before FinFET. For the active matrix display, there is one transistor for each pixel to drive the individual RGB within the pixel. As the resolution of the display grows, the transistor size also reduces, but not to the sub-micron scale of semiconductor devices. For the 325 PPI density, the transistor size is approximately 0.0001 mm2 and for the 4K TV with 80 PPI density, the transistor size is approximately 0.001 mm2.

Technology trends TFT-LCD (thin-film-transistor liquid-crystal display) is the baseline technology. MO / White OLED (organic light emitting diode) is used for larger screens. LTPS / AMOLED is used for small / medium screens. The challenges for OLED are the effect of < 1 micron particles on yield, much higher cost compared to a-Si due to increased mask steps, and moisture impact to yield for the OLED step.

Although AMLCD displays are still dominant in the market today, AMOLED displays are growing quickly. Currently about 25% of smartphones are made with AMOLED displays and this is expected to grow to ~40% by 2021. OLED televisions are also growing rapidly, enjoying double digit growth rate year over year. Based on IHS data, the revenue for display panels with AMOLED technol- ogies is expected to have a CAGR of 18.9% in the next five years while the AMLCD display revenue will have a -2.8% CAGR for the same period with the total display panel revenue CAGR of 2.5%. With the rapid growth of AMOLED display panels, the panel makers have accel- erated their investment in the equipment to produce AMOLED panels.

There are three types of thin-film-transistor devices for display: amorphous silicon (a-Si), low temperature polysilicon (LTPS), and metal oxide (MO), also known as transparent amorphous oxide semiconductor (TAOS). AMLCD panels typically use a-Si for lower-resolution displays and TVs while high-resolution displays use LTPS transistors, but this use is mainly limited to small and medium displays due to its higher costs and scalability limitations. AMOLED panels use LTPS and MO transistors where MO devices are typically used for TV and large displays (FIGURE 3).

This shift in technology also requires a change in the gases used in production of AMOLED panels as compared with the AMLCD panels. As shown in FIGURE 4, display manufacturing today uses a wide variety of gases.

These gases can be categorized into two types: Electronic Specialty gases (ESGs) and Electronic Bulk gases (EBGs) (FIGURE 5). Electronic Specialty gases such as silane, nitrogen trifluoride, fluorine (on-site generation), sulfur hexafluoride, ammonia, and phosphine mixtures make up 52% of the gases used in the manufacture of the displays while the Electronic Bulk gases–nitrogen, hydrogen, helium, oxygen, carbon dioxide, and argon – make up the remaining 48% of the gases used in the display manufacturing.

The key ga susage driver in the manufacturing of displays is PECVD (plasma-enhanced chemical vapor deposition), which accounts for 75% of the ESG spending, while dry etch is driving helium usage. LTPS and MO transistor production is driving nitrous oxide usage. The ESG usage for MO transistor production differs from what is shown in FIGURE 4: nitrous oxide makes up 63% of gas spend, nitrogen trifluoride 26%, silane 7%, and sulfur hexafluoride and ammonia together around 4%. Laser gases are used not only for lithography, but also for excimer laser annealing application in LTPS.

Silane: SiH4 is one of the most critical molecules in display manufacturing. It is used in conjunction with ammonia (NH3) to create the silicon nitride layer for a-Si transistor, with nitrogen (N2) to form the pre excimer laser anneal a-Si for the LTPS transistor, or with nitrous oxide (N2O) to form the silicon oxide layer of MO transistor.

Nitrogen trifluoride: NF3 is the single largest electronic material from spend and volume standpoint for a-Si and LTPS display production while being surpassed by N2O for MO production. NF3 is used for cleaning the PECVD chambers. This gas requires scalability to get the cost advantage necessary for the highly competitive market.

Nitrous oxide: Used in both LTPS and MO display production, N2O has surpassed NF3 to become the largest electronic material from spend and volume standpoint for MO production. N2O is a regional and localized product due to its low cost, making long supply chains with high logistic costs unfeasible. Averaging approximately 2 kg per 5.5 m2 of mother glass area, it requires around 240 tons per month for a typical 120K per month capacity generation 8.5 MO display production. The largest N2O compressed gas trailer can only deliver six tons of N2O each time and thus it becomes both costly and risky

Nitrogen: For a typical large display fab, N2 demand can be as high as 50,000 Nm3/hour, so an on-site generator, such as the Linde SPECTRA-N® 50,000, is a cost-effective solution that has the added benefit of an 8% reduction in CO2 (carbon dioxide) footprint over conventional nitrogen plants.

N2 On-site generators: Nitrogen is the largest consumed gas at the fab, and is required to be available before the first tools are brought to the fab. Like major semiconductor fabs, large display fabs require very large amounts of nitrogen, which can only be economically supplied by on-site plants.

Blended gases: Laser gases and dopants are supplied as blends of several different gases. Both the accuracy and precision of the blended products are important to maintain the display device fabrication operating within acceptable parameters.

The consumer demand for displays that offer increas- ingly vivid color, higher resolution, and lower power consumption will challenge display makers to step up the technologies they employ and to develop newer displays such as flexible and transparent displays. The transistors to support these new displays will either be LTPS and / or MO, which means the gases currently being used in these processes will continue to grow. Considering the current a-Si display production, the gas consumption per area of the glass will increase by 25% for LTPS and ~ 50% for MO productions.

To facilitate these increasing demands, display manufacturers must partner with gas suppliers to identify which can meet their technology needs, globally source electronic materials to provide customers with stable and cost- effective gas solutions, develop local sources of electronic materials, improve productivity, reduce carbon footprint, and increase energy efficiency through on-site gas plants. This is particularly true for the burgeoning China display manufacturing market, which will benefit from investing in on-site bulk gas plants and collaboration with global materials suppliers with local production facilities for high-purity gas and chemical manufacturing.

TFT screens have high speed and response time, which is highly suitable for the fast-growing industrial and digitalized world. Quick response time helps reduce the effects of blurring and ghosting in critical situations, which can be an issue if response time is too slow.

TFT cells are made from glass with laminated polarizers. These TFT displays can be use in plastic housing for a more rugged end product with less breakage in the electronics due to drops or stress tension.

The tried and trusted TFT is the display of choice for most industrial designs, but it does have its limitations in viewability and colour vibrancy. But what about the relatively new technology, IPS (in plane switching) which has turned the TFT into a super-TFT? What are the benefits and drawbacks of each?

IPS derives its name from the fact that the liquid-crystal molecules are aligned in parallel with the glass plates, whereas the TN principle adopted in conventional TFT displays is based on perpendicular alignment of the molecules. In an IPS display, the crystals remain oriented in parallel whether the pixel is turned on or off.

A TFT display is a form of Liquid Crystal Displaywith thin film transistors for controlling the image formation. The TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination. Discover our TFT Products

Because the pixels block light when in the off state (the opposite situation to conventional TFT), IPS TFT exhibits high contrast and the background is true black when the display is powered down.

Display choice really does depend on your application, end user and environment. It may be a higher-grade IPS is needed to satisfy outdoor requirements, or a lower cost standard TFT display is sufficient. Before you make your choice, why speak with us and we will be happy to talk you through your options.

When searching for a component supplier for visual displays, there are many options to explore. The benefits of TFT vs OLED or LCD displays are dependent on the end application, and with evolving technologies many companies are not aware of the current capabilities of the different offerings, or the challenges they may entail. Let Pace help you identify the solution that will work best for your product. Pace has extensive industry experience to help match the ideal visual display to your project priorities and price point.

Everyone is familiar with the TFT-LCD display screen. It is currently the most popular display product in the display industry. Its high reliability and good display effect are sure to have a wave of loyal fans. Then do you know the advantages and disadvantages of TFT-LCD display screen?

The hourly effect of the TFT-LCD display screen is very lifelike, and the color reproduction is far superior to other types of display screens. The picture presented to the user is bright in color, high in saturation, and the pure white and pure black pictures are very pure. It is very pure for professionals, one of the approved display screens.

The IPS series of the TFT-LCD display screen can reach a full viewing angle of 178 degrees, which means that no matter which angle the user views the TFT-LCD display screen from, the effect is very good.

The application of TFT-LCD display screen is very wide, used in industry, transportation, medical treatment, smart home, electric power, aviation and other fields. There must be a reason behind the widespread use. The size is complete, the interface types are many, and the development is simple. This is an important reason why the terminal chooses the TFT-LCD display screen.

Any product that is good will also have its bad aspects, and the shortcomings of the TFT-LCD display screen are reflected in the limitation of brightness. Due to its ultra-thin shape, it cannot meet the needs of ultra-high brightness. There are certain restrictions.

The display technology of TFT-LCD display screens has become mature, and the yield and production capacity of products are getting higher and higher, and the price of TFT-LCD display screens is becoming more and more affordable. These are all the reasons behind for the popularity of TFT-LCD display screens.
