The Samsung QN90B QLED is the best TV with an LED panel we"ve tested. It"s an impressive TV with amazing picture quality and a great selection of gaming features. It uses a Mini LED backlight, with way more dimming zones than most LED TVs, which allows for greater control over the local dimming feature for better dark room performance, with less distracting blooming around bright objects. It also gets exceptionally bright, meaning it can handle lots of glare in a bright room.
Based in South Korea, Samsung has become one of the world"s leading electronic brands. Like many companies in this list, their monitors mainly focus on gaming. Their models are unique since they don"t primarily use IPS panels, as many have VA panels with a high contrast ratio and curved screen. Although VA panels look great in dark rooms, the main downside is that they have narrow viewing angles, which isn"t ideal for sharing your screen with others. They"ve even started including Mini LED backlighting on some models, which further improves the picture quality, peak brightness, and dark room performance. It helps that Samsung already produces TVs with this Mini LED technology, so they"ve become an industry leader for monitors with it.
The Hisense U8H matches the excellent brightness and color performance of much pricier LCD TVs, and its Google TV smart platform is a welcome addition. But it’s available in only three screen sizes.
The Hisense U8H is the best LCD/LED TV for most people because it delivers the performance of a much pricier TV yet starts at under $1,000, for the smallest (55-inch) screen size. This TV utilizes quantum dots, a full-array backlight with mini-LEDs, and a 120 Hz refresh rate to deliver a great-looking 4K HDR image. It’s compatible with every major HDR format. And it’s equipped with two full-bandwidth HDMI 2.1 inputs to support 4K 120 Hz gaming from the newest Xbox and PlayStation consoles. Add in the intuitive, fully featured Google TV smart-TV platform, and the U8H’s price-to-performance ratio is of inarguable value.
In terms of design, the Hisense U8H is not as svelte as our upgrade pick, but it’s plenty sturdy and doesn’t look or feel cheap. Two narrow, metal feet jut out from beneath the panel and steadily hold the TV. They can be attached in two separate spots, either closer in toward the middle of the panel or out toward the edges, to account for different-size TV stands. The feet are also equipped with cable organization clasps—a nice touch for keeping your TV stand free of cable clutter. Though the TV is primarily plastic, its bezels are lined with metal strips, providing a bit more durability in the long run. I moved it around my home, and it was no worse for wear, but we’ll know more after doing some long-term testing.
The Hisense U8H has some difficulties with banding, or areas of uneven gradation, where transitions that should appear smooth instead look like “bands” of color (sometimes also called posterization). Like many current 4K HDR TVs, the U8H uses an 8-bit panel rather than a 10-bit panel, which affects the color decoding and color presentation process. This is usually relevant only with HDR video and games. When playing games on the PlayStation 5 and Xbox Series X, I saw a few instances where the content wasn’t rendered correctly and displayed ugly splotches of color on the screen. However, this almost always occurred during static screens (such as a pause menu or loading screen); I rarely spotted it during actual gameplay. Hisense has stated that it would address the problem in a future firmware update, but at the time of writing it was still present. This is a flaw that may give dedicated gamers pause, but we don’t consider it to be a dealbreaker for most people.
Finally, like most TVs that use vertical alignment (VA) LCD panels, the U8H has a limited horizontal viewing angle, which may be a bit annoying if you’re hoping to entertain a large crowd. Our upgrade pick uses a special wide-angle technology to address this.

Samsung has so far avoided producing OLED displays like those of LG. So, instead of striking a deal to use LG’s panels, Samsung branded its own LCD tech “QLED.” For a detailed breakdown, check out our QLED TV versus OLED TV comparison, but the general gist is this: QLED uses quantum dots to enhance performance by producing a purer, full-spectrum white light than LEDs are capable of on their own. In practice, QLED televisions are brighter (better for bright rooms) than less-expensive LCD TVs, and unlike OLED, can be more affordably built into large displays (100 inches and beyond).
OLED — Organic Light Emitting Diode — is the premier display technology today. OLED TV panels are capable of reaching black levels never before seen, with better contrast across the board, and because the pixels themselves light up, OLED televisions boast quicker response times (and less input lag) than other types of displays, and the picture integrity is stunning at any viewing distance. To see how OLED stacks up against regular old LED, take a look at our OLED vs. LED comparison.
Sony is one of a handful of companies offering OLED televisions (the list has recently expanded to include Panasonic, Philips, Hisense, and Vizio) thanks to a deal with LG allowing Sony to build TVs using LG panels. Due to the Cognitive Processor XR chip, Sony’s Bravia flagship TVs offer greater contrast, improved sound, low input lag, and faster web performance than we’ve ever seen. Sony’s newer TVs also offer VRR (Variable Refresh Rate) for gaming, particularly with the PlayStation 5.
Additionally, TCL expanded into Google TV territory last year with theirpopular 5- and 6-Series panels equipped with the latest Google TV operating system. While the new sets were briefly pulled from U.S. Best Buy shelves due to software issues, a fix was issued and the retailer now stocks the popular TVs again.
Chinese manufacturer Hisense has been steadily making moves in the TV market over the years, licensing Sharp’s brand name(and buying its North American factory outright in 2015), buying Toshiba’s business in 2017, and making TVs under all three names for the U.S. market. Hisense had a rocky start but found a rhythm in making value-conscious Quantum 4K panels. In fact, their quality has improved so much that one of the latest versions, the Hisense U7G with HDR support, is one of our new recommended picks for a TV under $1,000 — and it has new, affordable 8K TVs now as well.
With choices between Roku, Google TV, Fire TV, and more, buyers can pick the smart platform they like here, with plenty of options for budget-friendly purchases. The company is also making use of its TriChroma laser tech for improved color accuracy, and “ULED” panel technology to enhance images. Its latest Google TV picks also offer mini-LED panels, while the U6H Fire comes with Quantum Dot color, so you also have plenty of panel technologies to choose from. The latest 2022 models even have FreeSync and Game Mode Plus for gamers.
As with Samsung, Vizio is big on quantum-dot-powered panels. This is especially evident for the brand’s 2022 models, especially when it comes to the MQX and P-Series Quantum X series. And on top of quantum-enhanced colors and contrast, while you won’t find mini-LED tech on these 2022 models, the sheer number of traditional LED local dimming zones that are in place make for a totally arresting image packed with brightness, color detail, lifelike contrast, and minimal light blooming.
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.

Before you dive in to the individual models, it pays to understand the two basic technologies used in today’s televisions: LCD TVs, which are also called LED TVs for the LED backlights that illuminate the screen, and OLED TVs, where each pixel generates its own light.
Most TVs are LCD sets. While they generally can’t deliver OLED-like black levels, they get better every year, especially models that use full-array backlights, where the LEDs are spread across the entire rear panel instead of just along the edges. These models include a feature called local dimming, which divides the backlights into zones that can be dimmed or illuminated separately, depending on the scene. This can help improve black levels.
Typically, only pricier TVs have full-array backlights with local dimming. Other sets are edge-lit, with the LEDs positioned on the sides of the screen. Some of these sets also include local dimming, but it tends to be less effective than in sets with full-array backlights. The best LCD TVs can create very bright, vivid images.
No. Our tests show that not every TV with "HDR" written on the box produces equally rich, lifelike images. That’s one reason we now provide a separate HDR score in our TV ratings.
In our reviews, OLED TVs, which use organic light-emitting diode technology, have always had better picture quality than LED TVs, which are basically LCD TVs that use LED backlights. The main reason is that OLED TVs can produce a perfectly dark shade of black with no stray illumination of blooming, which leads to better contrast and pop. LED TVs can get brighter, however, and usually cost less than OLED TVs.

There’s a variety of display panel out there and even more on the way. But looking at all the different types of panels can be baffling. They come in various acronyms, and many of those acronyms are confusingly similar. How do LCD, LED and OLED compare? What about the different types of LCD panels? And how do these different technologies impact your viewing experience for things like gaming? To help, we’ve created this guide so you can gain a firm understanding of today’s display panel technology and which features really matter.
The first type of panels we’ll cover are LCD (liquid crystal display) panels. The main thing to understand about LCD panels is that they all use a white backlight (or sidelight, etc.). They work by shining a bright white light into your eyes, while the rest of the panel is for changing this backlight into individual pixels.
LED stands for light-emitting diode. You’ll often see LCD panels that are LED, but that doesn’t necessarily mean much when choosing an LCD. LED is just a different type of backlight compared to the old cold cathode backlights. While you could congratulate yourself on not using mercury, which is found in cathodes, at this point all LCDs use LED backlights anyway.
The second thing to understand is that LCDs take advantage of a phenomena known as polarization. Polarization is the direction in which the light wave is oscillating, or swinging back and forth at the same speed. Light comes out of the backlight unpolarized. It then passes through one polarizer, which makes all the light oscillate the same way.
Now you have an on and off (and between) switch for light. To produce color all that’s needed is three color filters, red, green and blue, that block all light other than that color from coming through. The difference between different types of LCD panels is mostly in how this in-between liquid crystal part works.
This design allows for fast response times (the time between the panel getting the frame it’s supposed to display and actually displaying it). It also allows for fast refresh rates. Consequently, TN panels are the only 240 hertz (Hz) gaming monitors available right now.
TN panels are cheap but suffer from poor viewing angles due to the “twist” only being aligned in one direction for viewing the panel straight on. They can also have poor color and contrast due to this twist mechanism not being the most precise or accurate.
VA stands for vertical alignment, again referring to the crystal alignment. These came about in the 1990s. Instead of using liquid crystals to twist a light’s polarization, a VA panel’s liquid crystals are aligned either perpendicular (vertical to) or parallel (horizontal to) the two polarizers. In the off state, the crystals are perpendicular to the two opposing polarizers. In the on state, the crystals begin to align horizontally, changing the polarization to match the second polarizer and allowing the light to go through the crystals.
This structure produces deeper blacks and better colors than TN panels. And multiple crystal alignments (shifted a bit off axis from each other) can allow for better viewing angles compared to TN panels.
However, VA panels come with a tradeoff, as they are often more expensive than TN panels and tend to have lower refresh rates and slower response times than TN panels. Consequently, you won’t see quite as many VA panel gaming monitors.
IPS stands for in-plane switching. These panels debuted after TN panels in the mid-1990s. The crystals are always horizontal to the two polarizers and twist 90° horizontally to go from off to on. Part of this design requires the two electrodes (which apply current to the liquid crystal to change its state) to be on the same glass substrate, instead of aligned with each other on the sandwiching glass substrates above and below the crystal (as in other types of LCDs). This, in turn, blocks a bit more light than both TN and VA panels.
IPS panels have the best viewing angles and colors of any LCD monitor type, thanks to its crystal alignment always lining up with the viewer. And while they don’t offer as fast a response time or refresh rate as TN panels, clever engineering has still gotten them to 144hz, and with nice viewing angles you’re not necessarily going wrong with an IPS gaming panel.
How do LCD panels go about reaching HDR brightness when incorrect polarization and color filters block so much light?The answer is quantum dots. These clever little things are molecules that absorb light and then re-emit that light in the color you engineered them to.
Today’s quantum dot layers usually go between a blue backlight and the polarization step, and are often used to produce red and green that more closely matches the color filters, so more light passes through them. This allows more of the backlight to come through instead of being blocked by the color filters, it can also reduce crosstalk, or colors slipping through the wrong subpixel, ensuring better colors of LCDs.
Other uses of quantum dots are being tried, however. One promising one is using QD molecules to replace the color filters entirely, allowing even more light through. Because LCD backlights produce more light than OLED panels (more on those below), this would allow LCDs to become the brightest displays around.
Motion blur/ghosting can be a result of how long an image takes to switch from one to another and how long an image is displayed on screen (persistence). But both of these phenomena differ greatly between individual LCD panels regardless of underlying LCD tech. And both are often better controlled by higher refresh rates, rather than clever panel engineering, at least for LCD displays.
Choosing an LCD panel based on underlying LCD tech should be more about cost vs desired contrast, viewing angles and color reproduction than expected blur, or other gaming attributes. Maximum refresh rate and response time should be listed in any respectable panel’s specs. Other gaming tech, such as strobe, which flashes the backlight on and off quickly to reduce persistence, may not be listed at all and is not part of the underlying type of LCD used. For that kind of info you’ll have to check the detailed reviews here on our site.
OLED, or organic light emitting diode, panels, are different from LCDs. There are no polarization tricks here. Instead, each pixel (or subpixel of red, green, or blue) lights itself up as a voltage is applied to a giant complex molecule called, yep, an organic light emitting diode. The color emitted is dependent on the molecule in question, and brightness is dependent on the voltage applied. OLEDs can reach HDR brightness because their molecules put out the right colors to begin with without being blocked.
Due to its approach to color and brightness, OLEDs have great contrast ratios. There’s no need to block a backlight, so there’s no worries about light bleeding through. Blacks are very black, and colors look great. OLEDs can also strobe, or flash off and on quickly to lower persistence. They can also use a trick called rolling scan.This turns blocks of the screen on and off one at a time, from top to bottom in a roll. This is all done as the image is sent to the screen, which cuts down on persistence blur a lot. This is why every major VR headset that can afford it uses OLED panels today.
Unfortunately, that’s where the advantages of OLED end. Refresh rates of OLED panels have never surpassed about 90Hz. And they’re quite expensive. A large part of that $1,000 iPhone X price is due to its OLED display. The current molecules used in OLEDs also degrade relatively quickly over time, especially those used for the color blue(opens in new tab), making the screen less and less bright.
OLEDs were also supposed to use less power than LCDs, but newer, giant OLED molecules that take less voltage to turn on have yet to appear. And while molecules covering the colors of the P3 HDR gamut are out today, those covering the larger BT.2020 gamut have yet to be found commercially. So OLEDs, while once promising and seemingly the future, have yet to live up to that promise.
A relevant question: If our fastest gaming displays are 240Hz TN panels now, just how fast do we need to go anyway? Well, a 2015 study places maximum human perception at 500Hz. So from that perspective, we’re halfway there. But that’s halfway there with today’s HDR, and not in lightfield 3D, or other possible advancements. And mobile devices could always use displays that take up less power.
In other words, in order to get fancy 3D effects, or much higher brightness, or any other desirable features, a different, new type of panel may be required. MicroLED tech is one such technology; think of it as OLED without the organic part and with the potential to improve contrast, response times and energy usage over standard LED panels. If you want to know more you can go here, but the real takeaway is that MicroLEDs work almost exactly like OLEDs.
Installed this new LCD and turned power on before assembling to check whether screen powers up. The rear (white side) of the screen lights up but not the front (black side). I suspect that the LCD panel was reversed during manufacturing. Ordered a replacement but don"t hold out much hope if it"s from the same batch. Will update if it works. Amazon customer service were great and gave me a refund without having to return the defective part.
UPDATE: Received the replacement LCD screen today and installed. Works fine. No problems. Screen resolution is sharp, bright and clear. My iPad mini 2 now has a new battery, LCD and digitizer screen. Good as new!!
