Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

Liquid Crystal Display (LCD) screens are a staple in the digital display marketplace and are used in display applications across every industry. With every display application presenting a unique set of requirements, the selection of specialized LCDs has grown to meet these demands.

LCD screens can be grouped into three categories: TN (twisted nematic), IPS (in-plane switching), and VA (Vertical Alignment). Each of these screen types has its own unique qualities, almost all of them having to do with how images appear across the various screen types.

This technology consists of nematic liquid crystal sandwiched between two plates of glass. When power is applied to the electrodes, the liquid crystals twist 90°. TN (Twisted Nematic) LCDs are the most common LCD screen type. They offer full-color images, and moderate viewing angles.

TN LCDs maintain a dedicated user base despite other screen types growing in popularity due to some unique key features that TN display offer. For one,

Refresh rates and response times refer to the time it takes pixels to activate and deactivate in response to user inputs; this is crucial for fast-moving images or graphics that must update as fast as possible with extreme precision.

VA, also known as Multi-Domain Vertical Alignment (MVA) dislays offer features found in both TN and IPS screens. The Pixels in VA displays align vertically to the glass substrate when voltage is applied, allowing light to pass through.

Displays with VA screens deliver wide viewing angles, high contrast, and good color reproduction. They maintain high response rates similar to TN TFTs but may not reach the same sunlight readable brightness levels as comparable TN or IPS LCDs. VA displays are generally best for applications that need to be viewed from multiple angles, like digital signage in a commercial setting.

IPS (In-Plane Switching) technology improves image quality by acting on the liquid crystal inside the display screen. When voltage is applied, the crystals rotate parallel (or “in-plane”) rather than upright to allow light to pass through. This behavior results in several significant improvements to the image quality of these screens.

IPS is superior in contrast, brightness, viewing angles, and color representation compared to TN screens. Images on screen retain their quality without becoming washed out or distorted, no matter what angle they’re viewed from. Because of this, viewers have the flexibility to view content on the screen from almost anywhere rather than having to look at the display from a front-center position.

IPS displays offer a slightly lower refresh rate than TN displays. Remember that the time for pixels to go from inactive to active is measured in milliseconds. So for most users, the difference in refresh rates will go unnoticed.

Based on current trends, IPS and TN screen types will be expected to remain the dominant formats for some time. As human interface display technology advances and new product designs are developed, customers will likely choose IPS LCDs to replace the similarly priced TN LCDs for their new projects.

The Hisense U7G offers great image quality, superb gaming features, and the Android TV interface, but it has a narrower viewing angle and comes in fewer screen sizes than some other TVs.

The Hisense U7G is a great-looking 4K TV with all the technologies and features that any LCD/LED TV should have today, including a full-array local-dimming backlight for superb black levels and image contrast as well as a 120 Hz refresh rate that delivers better motion quality than you’ll find on many competitors. It does a nice job showing high dynamic range video, thanks to its high brightness and rich color, and it supports the more advanced Dolby Vision HDR standard (which can offer improvements in image quality over the standard HDR10 format). For serious gamers, Hisense has also added all the HDMI 2.1 features necessary to take full advantage of the newest gaming consoles. (Check out TV features, defined for more explanation of the technical terms we’re using here.) The U7G features the Android TV streaming platform, which offers a wide variety of streaming services and a continually improving user interface. But the TV comes only in 55-, 65-, and 75-inch screen sizes.

The Samsung QN90A offers better contrast ratios, brighter HDR highlights, and a wider viewing angle than our top pick—in a larger selection of screen sizes.

If you’re willing to pay a higher price to get one of the best LCD performers we’ve tested, the Samsung QN90A is our recommendation. Moving beyond the standard LED backlight in the Hisense U7G, this TV has a mini-LED backlighting system—which offers more local-dimming zones for even better contrast ratios and brighter HDR highlights than on the Hisense—and it produces vibrant colors. It also has a wider viewing angle than our top pick, so everyone can enjoy a good-looking image no matter where they sit in the room, and it comes in more screen sizes, from 43 to 98 inches. The QN90A supports all the latest HDMI 2.1 features, which gamers will appreciate, and it uses Samsung’s proprietary Tizen streaming platform, which supports most of the popular streaming services. We like that it features a center stand so it will fit on virtually any TV furniture, and it sits high enough on the stand that you can place a soundbar in front of it without blocking the screen. The drawbacks are that the QN90A does not support the more advanced Dolby Vision high dynamic range format (but it does support the similarly advanced HDR10+ format), and it’s significantly more expensive than the Hisense U7G.

If you have a wider seating area, or if you regularly watch your TV from side angles, the Sony X950H uses an LCD panel specifically designed to produce a better-looking image at wider viewing angles than many 4K LCD TVs offer. (Our upgrade pick, the Samsung QN90A, employs a similarly effective wide-angle-viewing technology but costs more.) This TV also has Sony’s superb color accuracy and video-processing capability, so it’s better than the competition at removing banding artifacts. However, that wider viewing angle comes at the expense of the TV’s black level, which isn’t as dark as that of Hisense’s U7G or Samsung’s QN90A. Also, you don’t get the full complement of HDMI 2.1 features to improve the gaming experience. The Sony X950H is available in a variety of screen sizes, from 49 to 85 inches.

If you"ve ever left your LCD monitor on a single static screen for an extended period, say 24 hours or more, and then changed the on-screen image and seen a "ghost" of the previous screen, you"ve experienced Image Persistence. You can also sometimes see this phenomenon while traveling through an airport and seeing the flight status monitors. The good news is that the persistence is not permanent, unlike previous technologies such as plasma displays or CRTs.

The previous technologies of plasma displays and CRTs are phosphor-based, and extended static images create a "burn-in" that affects the properties of the phosphor material and create permanent damage. The damage is called burn-in, whereas static image "ghosts" on an LCD are Image Persistence. Image Persistence is not permanent damage and is reversible. Modern LCDs include design, driver ICs and chemical improvements that minimize these effects.

Image persistence can happen with any LCD panel, and almost all specifications will have some reference to image persistence. Many will have a specific criterion of acceptable levels of it.

To understand why image persistence happens, we must first understand the basic structure of an LCD TFT. Within the TFT, a voltage is applied to the liquid crystal material to align or twist the crystals in each pixel to allow light to pass through or block light, thus creating the on-screen image. By allowing a static image to remain on screen for an extended duration, the polarity of that voltage on the crystals remains. During this time, ions within the liquid crystal fluid will migrate to either the + or – electrode of the transistor (source or drain). As these ions accumulate on the electrodes, the voltage applied to the crystals to align or twist is no longer sufficient to completely change the image on-screen, resulting in a "ghost effect" from the previous image.

The best method for preventing Image Persistence is to avoid having any static images on the screen for an extended time. If the image changes periodically, the ion flow will never have an opportunity to accumulate on any internal electrode. However, depending upon the use of the display, it is not always possible to avoid static images on the screen. In cases such as these, there are steps that you can do to reduce the chance of persistence.

Switching off the displayduring periods of inactivity (sleeping mode) and arousing at necessary image changes would also be reflected as a positive side effect providing lower power consumption.

Panel manufacturers specifically test for the phenomenon and have designed the TFT cell and improved the purity of the liquid crystal fluid to minimize any effect of image persistence.

To create an LCD, you take two pieces ofpolarized glass. A special polymer that creates microscopic grooves in the surface is rubbed on the side of the glass that does not have the polarizing film on it. The grooves must be in the same direction as the polarizing film. You then add a coating of nematic liquid crystals to one of the filters. The grooves will cause the first layer of molecules to align with the filter"s orientation. Then add the second piece of glass with the polarizing film at a right angle to the first piece. Each successive layer of TN molecules will gradually twist until the uppermost layer is at a 90-degree angle to the bottom, matching the polarized glass filters.

As light strikes the first filter, it is polarized. The molecules in each layer then guide the light they receive to the next layer. As the light passes through the liquid crystal layers, the molecules also change the light"s plane of vibration to match their own angle. When the light reaches the far side of the liquid crystal substance, it vibrates at the same angle as the final layer of molecules. If the final layer is matched up with the second polarized glass filter, then the light will pass through.

If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas.

Building a simple LCD is easier than you think. Your start with the sandwich of glass and liquid crystals described above and add two transparent electrodes to it. For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it. The layers would look like this:

The LCD needed to do this job is very basic. It has a mirror (A) in back, which makes it reflective. Then, we add a piece of glass (B) with a polarizing film on the bottom side, and a common electrode plane (C) made of indium-tin oxide on top. A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D). Next comes another piece of glass (E) with an electrode in the shape of the rectangle on the bottom and, on top, another polarizing film (F), at a right angle to the first one.

The electrode is hooked up to a power source like a battery. When there is no current, light entering through the front of the LCD will simply hit the mirror and bounce right back out. But when the battery supplies current to the electrodes, the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle untwist and block the light in that region from passing through. That makes the LCD show the rectangle as a black area.

The best mid-range TV we"ve tested with an LED panel is the Hisense U8H. It"s an excellent TV overall, with fantastic contrast and an impressive Mini LED local dimming feature, delivering deep blacks in a dark room with very little distracting blooming around bright objects. It has exceptional peak brightness and reflection handling, ensuring it can easily overcome glare in a bright room. It has worse processing overall than the Samsung QN90A QLED, though, so it"s a bit of a step down. There"s more noticeable banding in areas of similar color, and it has slightly worse motion processing as well.

It"s a great TV for gaming, with many of the same great features found on the Samsung, including 4k @ 120Hz support from the Xbox Series X and PS5 consoles. It has a fast response time and incredibly low input lag, ensuring a smooth and responsive gaming experience, which is great for competitive gamers. It also has one advantage over the Samsung model, as all of its HDMI ports support HDMI 2.1 bandwidth, while the other TV only supports it on one port.
