tn lcd panel manufacturer

Most monitors sold today use a Twisted Nematic (TN) LCD panel. The advantage of this LCD technology is that it is cheap to produce and that TN panels can change state quickly, giving them the best response time  of all available LCD technologies. This makes the panels more appropriate for games that render fast image transitions. Thanks to the combination of low cost and rapid response time, TN displays are by far the most popular today.

The discovery of the TN effect was a revolution in flat screen technology and for all intents and purposes is it what brought LCD technology into the mainstream. The effect means that the liquid crystals are controlled and restructured into different molecular configurations under the influence of an electrical field. It requires that the liquid crystals can be turned between “on” and “off” states. This is achieved by letting the current pass through layers of film (hence the name Thin Film Transistor, or TFT). Twisting it 90 degrees lets no light through, whereas another state lets though the specific sub-pixel colors red, green or blue (RGB). If the red, green and blue sub-pixels are all fully lit, the pixel turns white.

The different layers of an LCD monitor can be seen on the right: The first is a vertical film that polarizes the incoming light, the second layer is a substrate with electrodes, the shapes of which will determine what shapes that appear on the screen. Layer number three is the one that is made up of Twisted Nematic crystals that control the flow of molecules. The fourth is another glass substrate; unlike the first, which is the vertical polarizing filter, this layer acts as the horizontal filter. The final layer is the surface that absorbs and retransmits the light source, whether it comes from more modern and power-efficient LEDs or compact fluorescents (image credit: Wikimedia Commons).

As previously mentioned, viewing angles and color reproduction are not areas where TN panels excel compared to other, more expensive displays. Seen from a steep angle, the image discolors quickly; viewed from below the picture can be very dark and looking at it too far from the top, the contrast can reverse itself, allowing light to dark shades and vice versa.

Although TN panels and monitors with this technology has great strides in recent years, the color accuracy is not on par with monitors using In Plane Switching (IPS) and Patterned Vertical Alignment (PVA) panels. On the other hand there are some significant drawbacks with these panels too.

First of all, they are more expensive than TN, and IPS, PVA and other high-end alternatives are less suitable for gamers, as they tend to have higher (=worse) response times. However, for color critical applications such as photography, video editing or web design, monitors with IPS and PVA are still the best choice.

Other weaknesses of TN is the moderate levels of contrast and the ability to produce blacks and whites accurately. However, today’s monitors are considerably better in this respect than they were just a few years ago.

While there are many different manufacturers of LCD monitors, the panels themselves are actually only manufactured by a relatively small selection of companies. The three main manufacturers tend to be Samsung, AU Optronics and LG.Display (previously LG.Philips), but there are also a range of other companies like Innolux and CPT which are used widely in the market. Below is a database of all the current panel modules manufactured in each size. These show the module number along with important information including panel technology and a detailed spec. This should provide a detailed list of panels used, and can give you some insight into what is used in any given LCD display.

Note:These are taken from manufacturer product documentation and panel resource websites. Specs are up to date to the best of our knowledge, and new panels will be added as and when they are produced. Where gaps are present, the detail is unknown or not listed in documentation. The colour depth specs are taken from the manufacturer, and so where they specify FRC and 8-bit etc, this is their listing. Absence of such in the table below does not necessarily mean they aren’t using FRC etc, just that this is how the manufacturer lists the spec on their site.

TN displays have a 90° or less twist (the rotation of the molecules from one plane of the display to the other). All passive direct drive, active matrix, and most passive low level (x2 to x32) multiplexed LCDs have a 90° twist.

The basic Twisted Nematic (TN) LCD consists of a layer of liquid crystal material supported by two glass plates. The liquid crystal material is a mixture of long, cylindrically shaped molecules with different electrical and optical properties, depending on direction.

The TN technology comes in a single coloration; it is Black characters on a gray background. It is the least expensive, but has the lowest visual quality, primarily in viewing angle.

TN stands for twisted nematic. This is a type of LED (a form of LCD) panel display technology. TN panels are characterized as being the fastest and cheapest among the other main types of display panels, VA (vertical alignment)and IPS (in-plane switching). As such, they work great for gaming monitors and gaming laptops. However, TN panels also offer the worst viewing angles and color when compared to VA and IPS panels.

Everyday, we look at LCD display, TV, cell phone, monitor. It becomes a necessity in modern society. LCD panel is the most important part of an LCD display. It determines LCD screen"s performance, e.g. brightness, contrast, color and viewing angle. Therefore, picking the right type of LCD panel is critical to your application.

These names reflect the alignment of crystal molecules inside the LCD, and how they change when they are charged electrically. All liquid crystal displays change the alignment of liquid crystal molecules to work, but the manner in which they do so can drastically affect the image quality and response time. Each panel type has its advantages and disadvantages. The easiest way to choose between them is to decide which attributes are most important to your project. It mainly depends on what you use your LCD display for, and your budget.

TN is the most mature technology in LCD panel manufacturing. When there is no voltage difference between the two transparent electrodes, liquid crystal molecules are twisted 90 degrees, in combination of upper and bottom polarizers, allows light to pass through LCD. As voltage applied, crystal molecules are untwisted and aligned to the same direction, blocking light.

In IPS panel, crystal molecules are parallel to the glass substrates at initial stage, LCD is off. When the in-plane electrodes is charged, crystal molecules are rotated, modifying light"s direction. Which lights up the LCD display.

As its name suggests, VA panel"s liquid crystals are aligned vertically without charged. When a voltage is applied, the molecules tilt and modifying light direction.

So in summary, TN panels twist, IPS panels use a parallel alignment and rotate, while VA panels use a perpendicular alignment and tilt. These difference create LCD display with distinctive performance.

IPS LCD is the clear winner in this aspect. It has 178/178 viewing angle ratings. Which means you can look at IPS LCD display from any angle without the image shifting in color and contrast. VA LCD has pretty wide viewing angle, too. But it has contrast shifts at off-center angles. As for TN LCD, viewing angle is its weakest point.

Most TN LCDs have 6-bits colors. Manufacturers use frame rate control (FRC) to enhance its color performance. For IPS and VA panels, you can still find 6-bits entry level LCD. But most of them are 8-bits. And IPS technology can provide natively 10-bits colors.

Color gamut is another part that VA and IPS panels shine at. The best TN LCD can reach sRGB gamut. VA panels typically start with full sRGB coverage, and get to around 90% DCI-P3 coverage. With IPS LCD panel, you could find the best ones full DCI-P3 and Adobe RGB coverage. That is why you see most professional grade LCD displays use IPS panel.

There is no inherent differences among the three panel technologies, because LCD backlight is the main factor here. However, there is a big gap in terms of contrast ratio. TN LCD panel tends to have the lowest value among the three. IPS LCD screen sits in the middle can reach 1500:1. For VA panel, the best one can exceed 4500:1 easily. VA LCD display provides far darker screen than TN & IPS. That is why they are used in vehicle dashboard.

TN panel does have an advantage when it comes to refresh rate. The panel offers the best refresh rate and response time. This is the reason why most gaming LCD monitors are made of TN panel.

TN LCD provides the best refresh rate and economic solution. If your application requires wide viewing angles and good color presentation, VA panel is probably the choice. While IPS has the best overall visual performance, in general it is more expensive than the other two.

A type of LCD panel technology. In this type of panel, when no electric current is running through the liquid crystal cells, the cells naturally align in a twisted form between two substrate panes of glass which blocks the transmission of light from the backlight. This renders the crystals opaque and results in a black display screen. When an electric current is applied, the liquid crystal cells untwist allowing light to pass through resulting in a white display screen. TN panels have relatively narrow viewing angles especially in the vertical direction and color reproduction is poor; however, they are economical and suitable for a wide-range of general uses, particularly with office tasks (e.g. word processing).

IPS display panels deliver the best colors and viewing angles compared to other popular display planes, including VA (vertical alignment) and TN (twisted nematic).

LCDs (liquid crystal displays). IPS changes the behavior of an LCD’s liquid crystals to produce a sharper, more accurate picture. This technique allows IPS displays to deliver a higher quality viewing experience than other screen types like TN or VA.

IPS acts on the liquid crystals inside an LCD, so when voltage is applied, the crystals rotate parallel (or in-plane), allowing light to pass through them easily. By reducing the amount of interference in the light being produced by the display, the final image on the screen will be much clearer.

IPS display screens and monitors offer the best quality in different environments (direct sunlight, low light, indoors, or outdoors) compared to TNs or VAs.

IPS LCDs require about 15% more power than a standard TN LCD. OLED displays require much less power than IPS types due to the fact that they don’t require a backlight. The LCD IPS technology is not the ideal solution if you need an energy-efficient display. You’re better off choosing an OLED or TN TFT for a low-power solution.

Because of the newer and more advanced technology found in IPS displays, they’re more expensive to manufacture. For a more cost-effective solution, a TN LCD would be a better choice.

Because of in-plane switching’s ability to boost viewing angles and retain color accuracy, it allows LCDs to compete with the high contrast images found on OLED displays.

In order to understand this problem, we first need to know the panel type of LCD. At present, the LCD panels are mainly divided into three categories, which are TN, VA and IPS.

TN panel, full name Twisted Nematic (twist nematic), because the production cost is relatively low, so it is the first popular panel in LCD. The advantage of TN panel is that the response time of GTG panel is very fast, and the gray scale response time of GTG is often up to 1ms, which is the lowest among all LCD panels, so many e-sports / game monitors use TN panel.

However, the shortcomings of the TN panel are also obvious, such as less output gray scale, white color, small visual angle and so on. 1080p is the most common resolution in the TN panel, and there are also some 27-inch QHD panels, and the latest panel can do 28-inch UHD. At present, the main manufacturers of TN panels are Samsung display (Samsung Display), LG, Youda Optoelectronics, Qunchuang Optoelectronics, China Picture Tube and so on.

Let"s talk about the VA panel. VA panel full name Vertical Alignment (vertical arrangement), its advantage lies in the contrast, VA panel is the highest contrast of all LCD panels, usually can reach 3000 VA 1, while the contrast of TN, IPS is only about 1000 VA 1, the intuitive feeling of high contrast is that black looks purer and the picture is more layered.

The gray scale response time of VA panel is faster than that of IPS, and some of them even reach the same 1ms as TN, while the visual angle of TN is much better than that of TN, which is consistent with the visual angle of IPS panel, and there is no light leakage problem of VA panel.

Finally, let"s talk about the IPS panel. IPS full name In-Plane Switching (plane conversion), its advantage is that the color performance is relatively good, and the visual angle is also relatively wide, horizontal and vertical visual angle can reach 178°, but the contrast is not as good as VA panel, and the problem of light leakage is also more prominent.

From the above carding, it is not difficult to see that each panel has its own advantages, but also some inherent shortcomings. For example, TN panel is better than fast response time, but the color and visual angle is not good; VA panel contrast is high, but there are still some differences in response time and color; IPS color is good, but there are long response time and light leakage problems.

So which panel to choose depends on the specific requirements, you can"t simply think that IPS must be better than VA, or VA must be better than TN. For example, heavy players of FPS games who value response time can choose the display of TN panel, designers who value visual angle and have certain requirements for color can choose the display of IPS panel, and friends who like to watch some high-contrast and more powerful pictures can choose the display of VA panel.
