SVA"s VR-30 boasts a spacious, 30-inch LCD screen with razor-sharp images, an internal NTSC tuner for convenient broadcast-television viewing, and a 1,280 x 768 (WXGA) native pixel resolution. Image quality is enhanced by a high (350:1) contrast ratio, an exceptional peak brightness of 450 candles/square meter, and wide (170 x 170 degrees) viewing angles. The stereo set pumps 5 watts per channel through its discrete speakers, which flank the screen.

The VR-30 is EDTV capable, meaning it accepts both 480i interlaced (standard resolution, as from VCRs and cable boxes) and 480p progressive-scan video signals from DTV set-top decoders and DVD players, and it also offers a built-in NTSC tuner for convenient broadcast-TV viewing.

LCD screens offer a number of benefits over CRT monitors and televisions, including general ease of use, freedom from eye strain (no screen flickering or radiation emissions), quiet operation (no high-pitch "flyback" noise, an issue with CRT TVs), accurate image geometry (no curvature distortion or susceptibility to magnetic interference from, say, speakers), long screen life (no risk of image burn-in), space savings, and light weight/easy positioning. They also tend to be cheaper and, to some eyes, slightly more natural looking than their plasma flat-panel counterparts, which usually "spec" higher (higher brightness, higher contrast ratio).

Many TVs use LCD (Liquid Crystal Display) panels that are lit by LED backlights. There are two popular types of LCD panels: In-Plane Switching (IPS) and Vertical Alignment (VA), and there are two main differences between each type. A VA panel usually has a high contrast ratio and narrow viewing angles. However, an IPS panel has low contrast and wide viewing angles. These are the main differences between each, and for the most part, panel type doesn"t affect other aspects of picture quality, like peak brightness, color gamut, or color accuracy.

For the purposes of this article, we"re going to compare two LED-backlit LCD TVs: the Sony X800H, which has an IPS panel, and the Hisense H9G, which has a VA panel. Due to their different panel types, there are three noticeable differences in picture quality: viewing angles, contrast, and black uniformity, so we"re going to look at each one.

Viewing angle refers to the angle at which you can watch the TV without seeing a noticeable drop in picture quality. IPS TVs are the clear winner here, as the image remains accurate when viewing from the side - you can see the differences in the videos above. This is their main advantage over VA panels. Most VA panel TVs have a noticeable loss in image accuracy when viewing from the side. The narrow viewing angle of VA-type TVs is also problematic when the TV is used as a PC monitor from up close since the edges of the display look washed out.

Contrast ratio is one of the most important factors when it comes to picture quality. It determines how well a TV displays blacks, so one with a good contrast displays deep blacks when viewed in the dark. However, if your TV has a low contrast ratio, you"ll notice that blacks look gray when viewed in the dark.

VA panels are far superior to IPS panels when it comes to this, so if you tend to watch movies in the dark, you likely want to get a TV with a VA panel. Most TVs use VA panels due to this main advantage, and high-end models may have a local dimming feature that further enhances black levels. On the other hand, IPS panels normally have low contrast, so blacks look closer to gray, but you may not notice the difference in contrast in bright environments.

Our black uniformity tests determine how well a TV displays a dark scene with a bright image in the center. Ideally, you want to see a completely black screen with the center cross being the only part that"s lit up, and this is important for people watching movies. No LED TV has perfect uniformity, and unlike viewing angles and contrast, the panel type doesn"t completely determine its black uniformity. However, most VA panels that we"ve tested have good black uniformity, while most IPS panels have sub-par black uniformity. This doesn"t mean that every VA panel TV has good uniformity, as this can change between units, and you can also improve uniformity using the local dimming feature.

LCDs function by having liquid crystals in little groups to form the pixels. These crystals react and change position when charged with electricity and, depending on their position, they allow a certain color of light to pass through.

TV manufacturers have come up with ways to improve LED TVs to increase picture quality. There are competing technologies, like OLED, which also present their own unique characteristics.

Unlike LED TVs, OLEDs don"t use a backlight and instead have self-emitting pixels. This allows the pixels to individually turn on and off, resulting in perfect blacks. This means that they also have perfect black uniformity as there"s no blooming around bright objects like on some LED TVs. They also have wide viewing angles, sometimes even wider than some IPS panels, so OLEDs are a good choice for wide seating arrangements.

However, the one major downside to OLEDs compared to LEDs is their risk of permanent burn-in. This could be problematic if you constantly watch content with static elements, like the news, or if you use it as a PC monitor. We don"t expect it to be an issue for people who watch varied content, but if you"re truly worried about it, LED TVs appear to be immune to burn-in.

Samsung released quantum dot TVs in 2015, which they later labeled as QLED in 2017. These TVs include a quantum dot layer between the LED backlights and the LCD panel to achieve a wider color gamut. Other companies like Vizio and TCL also use this quantum dot technology on their TVs. Adding this extra quantum dot layer doesn"t change the characteristics of the panel type; the VA panel on the TCL 6 Series/S635 2020 QLED still has a high contrast ratio and narrow viewing angles. Although most QLED TVs use VA panels, you can easily use an IPS panel as well.

Manufacturers have tried different techniques to improve the viewing angles on VA panels over the years, aiming to produce a perfect LCD panel with both wide viewing angles and high contrast. While they have yet to achieve that goal, a few TVs have hit the market that try to combine the best of both panel types. The first TVs with this viewing angle technology came out in 2018, and only a few high-end models like the Samsung Q90/Q90T QLED and the Sony X950H had this technology in 2020. These TVs are a bit unique, delivering noticeably better viewing angles than their pure VA counterparts, but still worse than true IPS panels. This comes at the expense of a lower contrast ratio, as these TVs have worse native contrast than most VA panels, but they"re still better than IPS panels. Combined with their local dimming features, they still produce deep blacks.

Below you can see the viewing angle videos for the Samsung Q90T and the Sony X950H. The image remains accurate at fairly wide angles on each TV, but the Samsung does a better job overall at making sure the image is still fairly accurate when viewing from the side.

Between IPS and VA panels, neither technology is inherently superior to the other as they both serve different purposes. In general, IPS TVs have wide viewing angles suitable for when you want to watch the big game or your favorite show in a large seating arrangement. They"re also beneficial for use as a PC monitor since the edges remain accurate if you sit up close. However, VA panels are a better choice for watching content in dark rooms, as their improved contrast allows them to display deep blacks. Choosing between the two is a series of trade-offs and qualities, so choosing the best TV for your needs depends on your usage.

The most common form of monitor or TV on the market is LCD or Liquid Crystal Display. As the name suggests, LCDs use liquid crystals that alter the light to generate a specific colour. So some form of backlighting is necessary. Often, it’s LED lighting. But there are multiple forms of backlighting.

LCDs have utilized CCFLs or cold cathode fluorescent lamps. An LCD panel lit with CCFL backlighting benefits from extremely uniform illumination for a pretty even level of brightness across the entire screen. However, this comes at the expense of picture quality. Unlike an LED TV, cold cathode fluorescent lamp LCD monitors lack dimming capabilities. Since the brightness level is even throughout the entire array, a darker portion of scenes might look overly lit or washed out. While that might not be as obvious in a room filled with ambient light, under ideal movie-watching conditions, or in a dark room, it’s noticeable. LED TVs have mostly replaced CCFL.

An LCD panel is transmissive rather than emissive. Composition depends on the specific form of LCD being used, but generally, pixels are made up of subpixel layers that comprise the RGB (red-green-blue) colour spectrum and control the light that passes through. A backlight is needed, and it’s usually LED for modern monitors.

While many newer TVs and monitors are marketed as LED TVs, it’s sort of the same as an LCD TV. Whereas LCD refers to a display type, LED points to the backlighting in liquid crystal display instead. As such, LED TV is a subset of LCD. Rather than CCFLs, LEDs are light-emitting diodes or semiconductor light sources which generate light when a current passes through.

LED TVs boast several different benefits. Physically, LED television tends to be slimmer than CCFL-based LCD panels, and viewing angles are generally better than on non-LED LCD monitors. So if you’re at an angle, the picture remains relatively clear nonetheless. LEDs are also extremely long-lasting as well as more energy-efficient. As such, you can expect a lengthy lifespan and low power draw. Chances are you’ll upgrade to a new telly, or an internal part will go out far before any LEDs cease functioning.

Further segmenting LED TVs down, you’ll find TN panels. A TN display or Twisted Nematic display offers a low-cost solution with low response time and low input lag. TN monitors sport high refresh rates, so 100Hz, 144Hz, or higher. Thus, many monitors marketed toward gamers feature TN technology. Unfortunately, while an affordable, fast panel may sound ideal, TN panels suffer from inferior colour reproduction and horrible viewing angles. A TN panel works so that liquid crystal molecules point at the viewer, and light polarizers are oriented at 90-degree angles.

Like TN, IPS or In-plane Switching displays are a subset of LED panels. IPS monitors tend to boast accurate colour reproduction and great viewing angles. Price is higher than on TN monitors, but in-plane switching TVs generally feature a better picture when compared with twisted nematic sets. Latency and response time can be higher on IPS monitors meaning not all are ideal for gaming.

A quantum dot LED TV or QLED is yet another form of LED television. But it’s drastically different from other LED variants. Whereas most LED panels use a white backlight, quantum dot televisions opt for blue lights. In front of these blue LEDs sits a thin layer of quantum dots. These quantum dots in a screen glow at specific wavelengths of colour, either red, green, or blue, therefore comprising the entire RGB (red-green-blue) colour spectrum required to create a colour TV image.

QLED TV sets are thus able to achieve many more local dimming zones than other LED TVs. As opposed to uniform backlighting, local dimming zones can vary backlighting into zones for adjustable lighting to show accurate light and dark scenes. Quantum Dot displays maintain an excellent, bright image with precise colour reproduction.

An OLED or organic light-emitting diode display isn’t another variation of LED. OLEDs use negatively and positively charged ions for illuminating individual pixels. By contrast, LCD/LED TVs use a backlight that can make an unwanted glow. In OLED display, there are several layers, including a substrate, anode, hole injection layer, hole transport layer, an emissive layer, blocking layer, electron transport layer, and cathode. The emissive layer comprised of an electroluminescent layer of film is nestled between an electron-injecting cathode and an electron removal layer, the anode. OLEDs benefit from darker blacks and eschew any unwanted screen glow. Because OLED panels are made up of millions of individual subpixels, the pixels themselves emit light, and it’s, therefore, an emissive display as opposed to a transmissive technology like LCD/LED panels where a backlight is required behind the pixels themselves.

Image quality is top-notch. OLED TVs feature superb local dimming capabilities. The contrast ratio is unrivalled, even by the best of QLEDs, since pixels not used may be turned off. There’s no light bleed, black levels are incredible, excellent screen uniformity, and viewing angles don’t degrade the picture. Unfortunately, this comes at a cost. OLEDs are pricey, and the image isn’t as bright overall when compared to LED panels. For viewing in a darkened room, that’s fine, but ambient lighting isn’t ideal for OLED use.

As you can see, there are tons of different types of displays, each with their advantages and disadvantages. Although many monitors and TVs are referred to by different names like LED, IPS, VA, TN, or QLED, many are variations of LCD panels. However, specific technology such as the colour of backlighting and alignment of pixels dictates the picture quality. OLED is an entirely different form of display that’s not LED. Now that you understand the various types of monitors and televisions on the market, you can select the best TV to fit your needs!

Because OLED TVs are newer and generally more expensive, the average buyer is looking at LED/LCD TVs right now. And although there are several features and specifications to consider while shopping—the brand name, HDR compatibility, and refresh rate, just to name a few—there’s one important hardware spec that isn’t widely advertised: LCD panel type.

LED/LCD TVs are so called because of the two things that make up their displays: an LED (Light Emitting Diode) backlight and an LCD (Liquid Crystal Display) panel for that backlight to shine through. LED backlights vary between a variety of implementations, but modern LCDs generally come in one of two panel technologies: IPS (In-Plane Switching) and VA (Vertical Alignment).

Unlike other hardware specifications (which are usually listed on the side of a TV box or on the manufacturer’s website), information about a TV’s LCD panel type is a bit more inside baseball. But panel type has a far greater impact on a TV’s performance than you might expect—it affects contrast, color, and viewing angle as well.

Individual pixels in an LCD display are made up of liquid crystals activated by voltage. How the display arranges its crystals is part of what sets IPS panels apart from VA panels.

IPS (In-Plane Switching) panels are a common display type for both the best computer monitors and TVs. Without getting too far down the rabbit hole, let’s talk a little about how IPS panels distinguish themselves from other types.

Every non-OLED TV on the market today is an LCD TV powered by LED lighting. Individual pixels in an LCD display are made up of liquid crystals activated by voltage—this is what produces color. An IPS panel aligns its crystals horizontally, parallel to the glass substrate.

IPS technology was developed in part to improve the color and wide viewing angle performance of a display. There"s also a range of variations under the IPS umbrella, including ADS, S-IPS, H-IPS, e-IPS, P-IPS, and PLS (Plane-to-Line Switching). But, while they all differ marginally from one another in operation, their core functionality (as compared to VA panels) is the same.

VA (Vertical Alignment) panels represent another common display type, used for both computer monitors and TVs, but especially for the latter where they greatly outnumber their IPS counterparts. Most LED/LCD TVs you"ll find on the market use a VA panel. While IPS panels align their liquid crystals horizontally, VA panels align them—you guessed it—vertically. They run perpendicular to the glass substrate rather than parallel to it. When met with voltage, the crystals tilt, letting light through and producing color.

TN (Twisted Nematic) is an older LCD display type. They"re still relatively common display types for computer monitors—thanks to their lightning fast response times and excellent handling of motion blur. TN panels aren"t typically used in TV production anymore, though.

A TV’s total viewing angle describes how much a viewer can move away from an ideal, head-on viewing position before the contrast and color of the picture begins to deteriorate. Due to the positioning of their liquid crystals, IPS panels excel in this department; they typically offer significantly more viewing flexibility than TVs with VA-style panels. In other words, IPS panels are more reliable for group viewings (or any situation where a viewer might need to sit at an off-angle).

While impressive color production is possible on both display types, IPS panels tend to offer wider colors, given the nature of their hardware. While a wider range of colors tends to spell better color accuracy, the advent of additional TV technologies like quantum-dot color have evened the playing field considerably. In other words, you’re far more likely to notice the benefits of an IPS TV’s wider viewing angle than you are to notice its tendency for wider color.

Here’s the final takeaway: IPS panels are significantly better than VA panels when it comes to viewing angle and somewhat better than VA panels when it comes to color. VA panels, however, almost always offer deeper black levels and better overall contrast. And because they block light better, TVs and monitors using VA panels tend to have better backlight uniformity regardless of LED backlight type.

Unfortunately, not only is it rare to find a TV’s panel type listed on a manufacturer’s website, but it’s increasingly rare for a brand to reveal a TV’s panel type at all—even when we contact brands directly for information. The reason for this caginess has everything to do with marketing; it’s better to keep shoppers focused on the bells, whistles, and impressive performance specs of a TV rather than its potential shortcomings.

To add to the confusion, it’s common for different sizes of the same TV series to mix and match display types; you might find that the 55-inch version of a TV features a VA-style display while the 75-inch model uses IPS.

Fortunately, it’s relatively easy to determine panel type if you have the proper equipment and you know what to look for. Certain test results and viewing characteristics act as tell-tale signs. This is why my colleagues and I make a point of discussing panel type in just about every TV review we publish, and why you should make a point of reading reviews before making a purchase.

Panel type is not the end-all-be-all for LED/LCD TVs. Many other factors, most of them related to the style and intensity of the LED backlight, can have a major impact on factors like contrast, viewing angle, and color intensity. Ultimately, you need to see a TV in person (and ideally in the space it’s going to live in) to get the best idea of how well it creates an image. But by knowing the core differences of IPS vs VA LCD panels, you can at least make some good guesses before you buy.

Unlike the best gaming monitors, IPS and VA TV panels are on an even playing field. TVs with both technologies are capable of high refresh rates of 120Hz, or occasionally 240Hz (although it usually comes at a premium).

If you’re buying a large screen and intend to host movie nights with friends and family, a TV with an IPS-style panel is far more accommodating thanks to its superior viewing angle. Just be aware that certain content—particularly dark content—won’t pop as much on account of the panel’s shallower black levels.

On the other hand, if you want the best possible picture overall, we recommend investing in a TV with a VA-style panel. They’re not always ideal candidates for group viewings, but the vast majority of the best non-OLED TVs you can buy feature this display type.

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.
