There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.VA

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.10 bits

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.1073741824 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Edge LED

With all the advantages and disadvantages, lcdds are essentially a good choice for those who see the TV starting from 4k smartphone. Nowadays, in addition to the wholesale models, lcdds are essentially a good option for those that don ’ t have the capacity of a device.

The number of special 3D eyeglasses included with the 3D TV. Some 3D TVs omit this item to control costs. Some 3D Blu-ray players may include these glasses. Retailers may offer a "3D TV + Blu-ray" bundle that also includes the glasses. All of the 3DTVs in our Ratings require the viewer to don special eyeglasses. So-called "active" 3D sets, which require "active" battery-powered LCD shutter glasses, may come with one or more pairs, or none. Additional pairs generally cost from $50 to $150 each. Most so-called "passive" 3D TVs come with four pairs of passive polarized glasses, much like the ones used in theaters, which don"t require batteries. Additional sets cost from $10 to $30 each. You cannot use passive glasses with 3DTV that requires active glasses, and vice-versa. You also generally cannot mix active 3D glasses from one brand of TV with another"s, though TVs made in 2012 and later may share glasses. (Passive 3D glasses can be used interchangeably with any passive 3D TVs.) There are some "universal" active 3D glasses you can buy as an after-market item .

The height of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.

The width of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.

The depth of the TV in inches, rounded up to the nearest 0.25-inch. Dimensions include the base and detachable speakers, important if you plan to place the TV on a stand or in an entertainment center. See "Panel size without base" if you plan to wall-mount only the display.

Dimensions of the display panel only, not including the base, rounded up to the nearest 0.25-inch. Also see "Overall height (in.)", "Overall width (in.)", and "Overall depth (in.)".

Fixed-pixel display types such as LCDs and OLEDs have a native resolution. It sets an upper limit of how sharp images may look. Native resolution is expressed in horizontal by vertical pixels (for example: 1920x1080 for an HD display, 3840x2160 for UHD).

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.

Think of an old-style, side-by-side, double-barreled shotgun. Each of those barrels contains a story about a very interesting recent development in TV-sized OLED display panels. But the barrels are twisted so they fire in completely different directions (Fig. 1). That is today"s Display Daily.

Barrel #1. Gijong Lee, writing in the Korean on-line publication The Elec five weeks ago, reported that Samsung Display (Samsung"s panel-making division) would produce QD-OLED TV prototypes in June. This is a surprise since nearly everybody, including a source within Samsung Visual (the set-making division), has been saying that Samsung Visual would not release QD-OLED sets before 2022. Lee went on to say that Samsung Display would send both TV and monitor prototypes to Samsung Visual, Sony and Chinese set-makers. (If you blinked recently, you may still be thinking that Samsung Visual had rejected the idea of making QD-OLED TV sets even though the panels would come from its corporate sibling. Well, it had, but that decision was recently reversed. OLED TVs – SDC, Samsung Visual and LGD – A Double Reversal of Fortune) Samsung Display plans to conduct a market response review in September.

The panels will be manufactured at Samsung Display"s Q1 production line, and Q1 could enter commercial production promptly if orders materialize. Samsung Display is already sending prototype panels to Samsung Visual, reported Lee.

In January, Samsung Display sent QD-OLED panel samples to Samsung Visual, but Samsung Visual said the panels had unacceptably low luminance. Another of Lee"s sources said Samsung Display planned to send new panel sample to Samsung Visual in April, the month that has just passed.

So I"m left with impression that QD-OLED sets may well be introduced in late 2021 and Samsung Visual is seriously interested in becoming a customer for the panels. But wait. The old shotgun"s second barrel hasn"t fired yet.

Barrel #2. Samsung Visual will acquire OLED panels from LG Display, reported Park Ji-eun in Money Today Broadcasting"s online outlet in April. This is startling: It"s like Churchill and Hitler sitting down to share cognac at Chequers, but Park provides details.

According to "industry officials," Park reports, senior management of the companies met recently and agreed that LGD would supply OLED panels to Samsung Visual. Park"s source stated that only working-level meetings are needed to finalize the details. The volume to be supplied "is known to be" one million units in H2"21 and four million units next year, which would be half of LGD"s total production capacity for 2021! Park reports an "industry insider" told him, "The meeting between the executives of the two companies in the past was led by the government, but this time it is meaningful in that it is a voluntary meeting."

LCD flat-panel televisions, with their decreasing price points and performance improvements, are now the dominant type of television sold. However, how much do you really know about these TVs, and are these your only choice? The following guide unveils the facts about LCD TVs that you need to know.

An LCD TV is a flat panel television that uses the same LCD (liquid crystal display) technology found in cellphones, camcorder viewfinders, and computer monitors.

LCD panels are made of two layers of a glass-like material, which are polarized and glued together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Electric current is passed through the individual crystals, which allows the crystals to pass or block light to create images.

LCD crystals do not produce light. An external light source, such as fluorescent or LED light bulbs, is needed for the image created by the LCD to become visible to the viewer.

LCD TV technology is resolution agnostic. In other words, LCD TVs can display a variety of resolutions, from 480p up to 8K, and, in the future, even higher depending on how TV makers want to provide consumers.

The LED designation on a TV refers to the LCD TV"s backlighting system, not the chips that produce the image content. LED TVs are still LCD TVs. These TVs use LED backlights rather than the fluorescent-type backlights of most other LCD TVs.

LED isn"t the only label that can be confusing with regards to LCD TVs. Another label that you might encounter is QLED, which is used mostly by Samsung and TCL. Vizio, on the other hand, uses the term Quantum.

These labels refer to TVs that use quantum dot technology to improve color performance. Quantum dots are an added layer of nano-sized particles, placed between an LED backlight and the LCD display layer in an LCD TV.

The dots are clustered in different sizes, with each size producing a specific color range when hit by the light from LEDs. The result is richer colors that can be displayed on an LCD TV screen, especially images at higher brightness levels.

Each pixel can be turned on and off individually, allowing OLED TVs to produce absolute black and more brilliant colors than either plasma or LCD. However, the main drawback is an overall lack of brightness. LCD TVs can produce higher brightness levels.

LCD and plasma TVs share one thing in common. Both are flat and thin and can be wall-mounted. However, inside those thin cabinets, these TVs employ different technologies to display images for TV viewing.

Plasma TVs use pixels made of self-emitting phosphors (a backlight isn"t required) to produce images. The advantage over LCD TVs is that each phosphor can be turned on and off individually, producing deeper blacks.

On the other end, plasma TVs can"t produce images as bright as an LCD TV. In addition, plasma TVs are subject to burn-in if a static image is displayed on the screen for too long a time period.

When shopping for an LCD or LED/LCD TV, you will hear terms like 60 Hz, 120 Hz, 240 Hz, MotionFlow, ClearScan, and more. What does this mean, and is it important when considering the purchase of an LCD or LED/LCD TV?

Those numbers and terms refer to how an LCD TV can handle motion. Although LCD TVs can produce bright, colorful images, one problem these TVs had from the outset is that the motion response isn"t that natural. Without some enhancement, fast-moving images on LCD TVs can exhibit lag or jerkiness.

Before you purchase an LCD TV, in addition to the core technologies discussed above, there are other things to take into consideration so that a specific brand and model is right for you.

Viewing angle: One weakness of LCD TVs is the relatively narrow viewing angle. You get the best results at the center seating position and good results within 30 to 45 degrees on either side of the center spot. However, as you move farther to either side, you"ll notice picture fading and color shifting. OLED and plasma TVs are less prone to this problem.

Connections: Depending on the brand and model of the TV, the type and number of connections may vary. Generally speaking, you can connect both an old VCR and the latest Blu-ray Disc player. If you have older analog gear (such as a VCR or DVD player without an HDMI connection), there are a growing number of TVs (both LCD and OLED) that may have limited options.

Smart TV: Most LCD TVs are equipped with some smart features. This allows you to stream content, such as Netflix, directly to your TV without an external device, provided the TV is connected to the internet.

Sound options: All LCD TVs come with built-in speakers, but the sound quality is often not good. If the sound quality isn"t satisfying, connect the TV to an external sound system, such as a soundbar or a home theater audio system. All LCD TVs, except for some with small screen sizes, can connect to an external audio system. Most have analog and digital connection options. Still, depending on the brand and model, only the digital connection option may be offered.
