lcd panel contrast ratio pricelist
OLED is short for “Organic Light Emitting Diode“. This type of monitor is made of organic material (such as plastic, wood, carbon and polymers), that is used to convert electric current into light. It can be thinner or lighter with a higher contrast ratio than LCDs. Tests have shown that these monitors are the best for watching movies.
LED stands for ‘Light Emitting Diode’. This type is the latest innovation on the market. These types of monitors are panel displays that use light-emitting diodes for backlighting on the screen.
LCD is short for ‘Liquid Crystal Display’. This monitor is made of liquid crystals. It is the most used monitor worldwide. It requires less space, consumes less electricity, and in expert opinion produces less heat than an old CRT monitor.
PDP stands for Plasma monitor panel. These monitors are made of Plasma technology. This technology is one of the latest types of computer monitor technology. According to expert opinions and various tests, compared to LCDs this type of display offers superior performance time, a much wider viewing angle and a good response.
Monitors are very important compliments to computer units, regardless of whether they are used for work, leisure in general or gaming in particular. In either situation, it is important to take into consideration a few important criteria before making a final purchase. In this section, we leave you with one last set of criteria to evaluate in any product you choose.
On the other hand, if you’re looking for a screen to help you immerse in the world of gaming, various tests have shown that there will be other parameters you must consider. For instance, the monitor you choose should have a good dynamic contrast ratio and a high refresh rate. For film and series lovers, a monitor with good resolution will be important.
This may seem trivial, but keep in mind that the monitor you choose will be featured prominently wherever you choose to set it up. For this reason, it would be good for it to have an appealing design that fits in harmoniously in the environment it exists in. Colour and shape will be part of this consideration, however, thickness will likely play a more important role.
The aspect ratio of a monitor is the ratio between the height and width of a monitor. This parameter is closely linked to the resolution component we mentioned above. With the wide selection of products available, you’ll find that there are also many different aspect ratios, however, the most common one is 16:9.
To explain a little more, a Full HD screen, i.e. 1920 x 1080 pixels, would have this aspect ratio. At the end of the day, it’s a matter of proportions. In other words, for every 9 vertical pixels, there are 16 horizontal pixels. Another aspect ratio, increasingly used, is 21:9; this is a more panoramic ratio.
It is important to note that the aspect ratio does not affect image quality. For instance, let’s consider a screen with a 1920 x 1080 resolution and another with 7680 x 4320. Both have a 16:9 aspect ratio. However, the second would have a higher image quality. Keep in mind that a 4:3 aspect ratio was popular years ago, but is now in decline.
The contrast ratio of a monitor is the difference between the brightest pixel and the darkest pixel. For example, a 1000:1 monitor contrast ratio means that the whitest pixel is a thousand times brighter than the darkest pixel. A higher proportion of these numbers will result in more contrasting and sharper images. It should be noted that there are two types of contrast ratio: static and dynamic.
In the first one, all the brightness of the screen changes at the same time. It is most ideal for working with still images. With dynamic contrast ratio (DCR) on the other hand, the brightness automatically adjusts as the video plays, to make the dark areas darker and the light spots brighter. This aspect heavily influences image detail and quality.
IPS stands for in-plane switching, a type of LED display panel technology. IPS panels are characterized as having the best color and viewing angles among the other main types of display panels. IPS displays incorporate a series of liquid crystals which work to prevent light leaking.
Simply put, an IPS monitor is an LCD (Liquid Crystal Display) with a back layer of LED bulbs. IPS-type panels are particularly suitable for images showing rapid movement. This technology prevents distortions, whether in a video game or a movie. However, keep in mind that IPS panels are also the most expensive ones on the market today.
There’s an almost overwhelming amount of options in the display market: OLED, MicroLED, and TN panel types just to name a few. But if you’re looking for a gaming monitor or simply don’t want to drain your bank account on a display, IPS and VA are generally the best choices. In-plane switching (or IPS) is an LCD-based technology that is used in just about every kind of display, whereas Vertical Alignment (or VA) is a more niche LCD technology used in gaming monitors, gaming TVs, and wide displays.
Although IPS is much more popular than VA and is often seen as the more premium option, both panel types have strengths and weaknesses that you should consider before you buy.
IPS panels have traditionally been used for making displays that have high color accuracy and large coverage of wide color gamuts like DCI-P3 or Adobe sRGB. Not only do IPS displays usually look good, but they also look good from wider angles, so you don’t need to look exactly head on at an IPS monitor to get accurate colors.
Although IPS is generally better than VA when it comes to color accuracy and coverage, VA panels have perfectly fine color accuracy and coverage for the vast majority of users. Only professional photo and video editors could really be disappointed with a VA monitor that only covers 90% of the DCI-P3 color space, which is actually a very good amount of coverage for gamers and content consumers.
Contrast ratio is a metric that measures how dark the color black is depicted on a display, measured as a ratio of x:1. The higher x is, the better. Although IPS is very good with color accuracy in general, it really struggles with making the color black, and even the best IPS monitors and TVs can only show a very dark grey rather than true black. Most IPS monitors are rated at a 1000:1 contrast ratio, which isn’t terrible but isn’t great either. Some monitors can get up to around 2000:1 however.
Despite VA’s general color accuracy issues, it’s actually amazing at depicting black as truly black. Even the worst VA displays can easily muster a 2000:1 contrast ratio, and some can even achieve higher than 5000:1. In fact, VA is second only to OLED when it comes to contrast ratio, and OLED actually delivers perfect contrast ratios of ∞:1. Because of this, a VA display can look better than an IPS counterpart in darker scenes.
Some displays can boost contrast ratio by using local dimming and HDR. By using a more complex backlight with multiple LEDs that can be turned on or off, local dimming helps IPS and VA displays look even darker when it matters. On the other end of the spectrum, HDR boosts brightness for colors that need it. With these two factors combined, some displays can boost the contrast ratio significantly. However, these features aren’t going to make an IPS display’s contrast ratio as good as the average VA display’s, and poorly implemented local dimming can backfire by creating more visual problems than it solves.
Although the best IPS panels beat the best VA panels when it comes to response time, there are plenty of IPS displays that have very bad response times. It’s also worth noting that response time only needs to be equal to the refresh rate of the monitor for there to be no smearing. On a 60Hz display, for instance, it takes 16.66ms to show a new image, so a response time of 1ms doesn’t really do much. Response time matters much more at higher refresh rates, and even at 144Hz a response time of around 7ms is sufficient to avoid ghosting.
While OLED may be seen by many as the future of mobile and large panel displays, LCD manufacturers have recently come along with a number of innovations breathing new life into the panel type, including Quantum Dot and fast refresh rate technology. Today, Panasonic has unveiled its latest LCD IPS display that boasts a 1,000,000:1 contrast ratio. That’s up to 600 times more contrast than some of the company’s conventional LCD panels, which offer around 1800:1 ratios, and rivals OLED specifications.
Panasonic has accomplished this through the use of its new light modulating cell technology, which allows the company to switch off individual pixels in the display using a secondary control layer. Typically, LCD backlights mean that either the entire or only large parts of the display can be dimmed at any one time. OLED panels switch of lights entirely for a black pixel to offer very high contrast ratios, and this new LCD technology works on a very similar principle. This is particularly important for reproducing HDR video content, which is becoming increasingly popular.
Furthermore, this new light modulating cell technology allows Panasonic to increase the peak brightness and stability of the display, which can reach 1,000 cd/m2 while also providing HDR colors. Many other HDR TV panels top out in the range of 700 to 800 cd/m2, so colors, highlights, and shadows should appear vivid and realistic.
Unfortunately, Panasonic’s new technology is quite expensive and won’t be heading to small form factor mobile panels, at least not yet. Although it can be built on existing LCD manufacturing lines, so prices should come down. The company states that it will be targeting the technology at panels in the high-end broadcasting, video production, medical, and automotive fields first, with sizes ranging from 55 to 12 inches. Sample shipments are scheduled to begin in January 2017, so we won’t see it in products for a little while yet.
OLED displays have higher contrast ratios (1 million : 1 static compared with 1,000 : 1 for LCD screens), deeper blacks and lower power consumption compared with LCD displays. They also have greater color accuracy. However, they are more expensive, and blue OLEDs have a shorter lifetime.
OLED displays offer a much better viewing angle. In contrast, viewing angle is limited with LCD displays. And even inside the supported viewing angle, the quality of the picture on an LCD screen is not consistent; it varies in brightness, contrast, saturation and hue by variations in posture of the viewer.
There are no geographical constraints with OLED screens. LCD screens, on the other hand, lose contrast in high temperature environments, and lose brightness and speed in low temperature environments.
With current technology, OLED displays use more energy than backlit LCDs when displaying light colors. While OLED displays have deeper blacks compared with backlit LCD displays, they have dimmer whites.
LCDs use liquid crystals that twist and untwist in response to an electric charge and are lit by a backlight. When a current runs through them, they untwist to let through a specific amount of light. They are then paired with color filters to create the display.
Lenovo has finally rolled out the Lenovo Tab M9 with amazing specifications and features. It is the successor of the Lenovo Tab M8 4th Generation tablet. The latest offering by Lenovo serves as an entry-level…
LCDs don’t emit light on their own and must instead have a backlight that shines through the LCD material to display an image. Today’s LCD-based displays use a number of LEDs for the backlighting. To achieve a greater contrast ratio than a standard dynamic range display, the LEDs in the backlight change their brightness level, allowing the display to dim the backlight for darker blacks and brighten it for brighter whites, which creates a wider contrast ratio. There are several different dimming designs that can be used in the backlight to accomplish this.
Global Dimming: The backlight, which consists of a string of LEDs on one edge of the LCD panel, is treated as a single “zone” and is dimmed for dark scenes and brightened for bright scenes. This is the least expensive type of dimming and can be accomplished with a standard LCD panel. This approach works well for scenes with a limited dynamic range. This type of dimming is typically found on notebooks as it has the lowest power consumption of any dimming technique and generates the least amount of heat. The disadvantage of this design is that the simultaneous contrast ratio is never greater than the contrast ratio of the LCD panel, usually around 1000:1.
1D Local Dimming: This design also uses an “edge-lit” string of LEDs, but in this case groups of LEDs on the string can be independently controlled. For most displays, the string of LEDs is located at the bottom of the panel, resulting in a number of vertical zones, equally spaced across the horizontal edge of the display. An edge-lit LED string typically contains between eight and sixteen LED groups, resulting in eight to sixteen dimming zones. This design allows for simultaneous contrast ratios of 6,000:1 to 100,000:1. 1D local dimming is currently the most common design found in HDR televisions and displays.
1.5D Local Dimming: Similar to the 1D local dimming, using edge lighting. However in this design an LED lighting string exists on two sides of the panel, typically top and bottom although left and right designs also exists. The advantage of this design is that it typically has 2×16 zones, so twice as many zones as 1D, but more importantly the top and the bottom of the screen are independently controlled, versus the 1D design where each zone is typically the full vertical height of the screen.
2D or Full array local dimming (FALD): In this design the backlight LEDs are moved from the edge of the panel to the rear of the panel and are arranged in a two-dimensional matrix of LEDs. Each LED is independently controlled and adjusts the brightness of just one “square of a checkerboard” on the display, although typically they are rectangles rather than perfect squares. Today’s HDR displays and televisions typically have between 384 and 1152 zones. These designs are the most expensive, due to the complexity of the circuitry and the processing demands required. The design can also generate a large amount of heat, and often requires cooling fans and/or heat sinks to be placed behind the LCD panel to draw heat away from the display electronics. Full array local dimming produces the best image quality of all of these designs and can achieve simultaneous contrast ratios of 20,000:1 to 500,000:1. Due to the high cost of this design, these displays command the highest prices and typically cost thousands of dollars.
