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:

Sony produces and sells commercial MicroLED displays called CLEDIS (Crystal-LED Integrated Displays, also called Canvas-LED) in small quantities.video walls.

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.

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.

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,

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.

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 general consumer typically has very limited knowledge about the different types of LCD panels on the market and they take all of the information, specifications, and features printed on the packaging to heart. The reality is that advertisers tend to take advantage of the fact that most people conduct very minimal research before making big technological purchases—in fact, they depend on this to sell higher quantities of commercial monitors. With that in mind, how exactly do you know if you’re actually getting a good quality product that’ll suit your needs? Reading up on all of the different types of industrial LCD monitors is a good place to start!

LCD stands for liquid-crystal display. Over the years, LCD technology has become ubiquitous with various commercial and industrial screen manufacturing. LCDs are constructed of flat panels that contain liquid crystals with light modulating properties. This means that these liquid crystals use a backlight or reflector to emit light and produce either monochromatic or coloured images. LCDs are used to construct all sorts of displays from cellphones to computer screens to flat-screen TVs. Keep reading to learn everything you need to know about the different types of LCD displays on the market.

Twisted Nematic LCDs are the most commonly manufactured and used types of monitors across a wide range of industries. They’re most commonly used by gamers because they’re inexpensive and boast faster response times than most of the other display types on this list. The only real downside to these monitors is that they possess low quality and limited contrast ratios, colour reproduction, and viewing angles. However, they suffice for everyday operations.

In Plane Switching displays are considered to be among the best of the best when it comes to LCD technology as they offer superior viewing angles, excellent image quality, and vibrant colour accuracy and contrast. They’re most commonly used by graphic designers and in other applications that require the highest possible standards for image and colour reproduction.

Vertical Alignment panels fall somewhere in the middle between TN and IPS panel technology. While they have much better viewing angles and higher quality colour reproduction features than TN panels, they also tend to have significantly slower response times. However, even their most positive aspects still don’t come anywhere close to holding a candle to IPS panels, which is why they’re much more affordable and suitable for everyday use.

AFFS LCDs offers far superior performance and a wider range of colour reproduction than even IPS panel technology. The applications involved in this type of LCD display are so advanced that they can minimize colour distortion without compromising on the extremely wide viewing angle. This screen is typically used in highly advanced and professional environments such as in the cockpits of commercial airplanes.

The most basic LCD introduced above is called passive matrix LCDs which can be found mostly in low end or simple applications like, calculators, utility meters, early time digital watches, alarm clocks etc. Passive matrix LCDs have a lot of limitations, like the narrow viewing angle, slow response speed, dim, but it is great for power consumption.

In order to improve upon the drawbacks, scientists and engineers developed active matrix LCD technology. The most widely used is TFT (Thin Film Transistor) LCD technology. Based on TFT LCD, even more modern LCD technologies are developed. The best known is IPS (In Plane Switching) LCD. It has super wide viewing angle, superior image picture quality, fast response, great contrast, less burn-in defects etc.

IPS LCDs are widely used in LCD monitors, LCD TVs, Iphone, pads etc. Samsung even revolutionized the LED backlighting to be QLED (quantum dot) to switch off LEDs wherever light is not needed to produce deeper blacks.

– Twisted Nematic Display: The TN (Twisted Nematic) LCDs production can be done most frequently and used different kinds of displays all over the industries. These displays are most frequently used by gamers as they are cheap & have quick response time as compared with other displays. The main disadvantage of these displays is that they have low quality as well as partial contrast ratios, viewing angles & reproduction of color. But, these devices are sufficient for daily operations.

– In-Plane Switching Display:IPS displays are considered to be the best LCD because they provide good image quality, higher viewing angles, vibrant color precision & difference. These displays are mostly used by graphic designers & in some other applications, LCDs need the maximum potential standards for the reproduction of image & color.

– Vertical Alignment Panel: The vertical alignment (VA) panels drop anywhere in the center among Twisted Nematic and in-plane switching panel technology. These panels have the best viewing angles as well as color reproduction with higher quality features as compared with TN type displays. These panels have a low response time. But, these are much more reasonable and appropriate for daily use.

– The structure of this panel generates deeper blacks as well as better colors as compared with the twisted nematic display. And several crystal alignments can permit for better viewing angles as compared with TN type displays. These displays arrive with a tradeoff because they are expensive as compared with other displays. And also they have slow response times & low refresh rates.

– Advanced Fringe Field Switching (AFFS): AFFS LCDs offer the best performance & a wide range of color reproduction as compared with IPS displays. The applications of AFFS are very advanced because they can reduce the distortion of color without compromising on the broad viewing angle. Usually, this display is used in highly advanced as well as professional surroundings like in the viable airplane cockpits.

– Passive and Active Matrix Displays: The Passive-matrix type LCDs works with a simple grid so that charge can be supplied to a specific pixel on the LCD. One glass layer gives columns whereas the other one gives rows that are designed by using a clear conductive material like indium-tin-oxide. The passive-matrix system has major drawbacks particularly response time is slow & inaccurate voltage control. The response time of the display mainly refers to the capability of the display to refresh the displayed image.

– Active-matrix type LCDs mainly depend on TFT (thin-film transistors). These transistors are small switching transistors as well as capacitors which are placed within a matrix over a glass substrate. When the proper row is activated then a charge can be transmitted down the exact column so that a specific pixel can be addressed, because all of the additional rows that the column intersects are switched OFF, simply the capacitor next to the designated pixel gets a charge.

LCD technologies have great advantages of light, thin, low power consumption which made wall TVs, laptops, smartphones, pad possible. On its way to progress, it wiped out the competition of many display technologies. We don’t see CRT monitors on our desks and plasma displays TV at our home anymore. LCD Technologies dominant the display market now. But any technology has the limitations.

LCD technologies have slow response times especially at low temperature, limited viewing angles, backlighting is needed. Focus on LCD drawbacks, OLED (Organic Light Emitting Diodes) technology was developed. Some high-end TV and mobile phones start to use AMOLED (Active Matrix Organic Light Emitting Diodes) displays.

This cutting-edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology. Please note, OLED displays include AMOLED and PMOLED (Passive Matrix Organic Light Emitting Diodes). What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED.

The display industry has come a long way in recent years. With so many competing standards on the market today, it’s often hard to tell if an emerging technology is worth paying extra for. OLED and QLED, for instance, sound similar enough on the surface but are, in fact, completely different display types.

To help with that decision, we’ve summarized all mainstream display types in this article, along with the pros and cons of each. Consider bookmarking this page and returning to it the next time you’re in the market for a new television, monitor, or smartphone.

LCDs, or liquid crystal displays, are the oldest of all display types on this list. They are made up of two primary components: a backlight and a liquid crystal layer.

Since liquid crystals don’t produce any light by themselves, LCDs rely on a white (or sometimes blue) backlight. The liquid crystal layer then simply has to let this light pass through, depending on the image that needs to be displayed.

You may have noticed that the term LCD has started to disappear of late, especially in the television industry. Instead, many manufacturers now prefer branding their televisions as LED models instead of LCD. Don’t be fooled, though — this is just a marketing ploy.

These so-called LED displays still use a liquid crystal layer. The only difference is that the backlights used to illuminate the display now use LEDs instead of cathode fluorescent lamps, or CFLs. LEDs are a better light source than CFLs in almost every way. They are smaller, consume lesser power, and last longer. However, the displays are still fundamentally LCDs.

Twisted nematic, or TN, was the very first LCD technology. Developed in the late 20th century, it paved the way for the display industry to transition away from CRT.

TN panels have been around for decades in devices like handheld calculators and digital watches. In these applications, you only need to power sections of the display where you don’t want light. In other words, it is an incredibly energy-efficient technology. Twisted nematic panels are also cheap to manufacture.

In the early 2010s, many smartphone manufacturers used TN panels as a way to keep costs down. However, the industry has almost entirely moved away from it. The same holds true for televisions, where wide viewing angles are a critical selling point, if not a necessity.

Instead of a twisted orientation, liquid crystals in an IPS display are oriented parallel to the panel. In this default state, light is blocked — the exact opposite of what happens in a TN display. Then, when a voltage is applied, the crystals simply rotate in the same plane and let light through. As a side note, this is why the technology is called in-plane switching.

IPS displays were originally developed to deliver wider viewing angles than TN. However, they also offer a myriad of other benefits, including higher color accuracy and bit-depth. While most TN panels are limited to the sRGB color space, IPS can support more expansive gamuts. These parameters are important for playing back HDR content and are downright necessary for creative professionals.

In a VA panel, liquid crystals are oriented vertically instead of horizontally. In other words, they are perpendicular to the panel, and not parallel like in IPS.

This default vertical arrangement blocks a lot more of the backlight from coming through to the front of the display. Consequently, VA panels are known for producing deeper blacks and offering better contrast compared to other LCD display types. As for bit-depth and color gamut coverage, VA is capable of doing just as well as IPS.

On the downside, the technology is still relatively immature. Early VA implementations suffered from extremely slow response times. This led to ghosting, or shadows behind fast-moving objects. The reason for this is simple — it takes longer for VA’s perpendicular arrangement of crystals to change orientation.

However, VA displays also have narrower viewing angles than IPS panels. Still, most VAs come out on top when compared to even the best TN implementations.

OLED stands for Organic Light Emitting Diode. The organic part here simply refers to carbon-based chemical compounds. These compounds are electroluminescent, which means that they emit light in response to an electric current.

From this description alone, it’s easy to see how OLED differs from LCD and prior display types. Since the compounds used in OLEDs emit their own light, they are an emissive technology. In other words, you don’t need a backlight for OLEDs. This is why OLEDs are universally thinner and lighter than LCD panels.

Since each organic molecule in an OLED panel is emissive, you can control whether a particular pixel is lit up or not. Take away the current and the pixel turns off. This simple principle allows OLEDs to achieve remarkable black levels, outperforming LCDs that are forced to use an always-on backlight. Besides delivering a high contrast ratio, turning off pixels also reduces power consumption.

The contrast alone would make the technology worth it, but other benefits exist too. OLEDs boast high color accuracy and are extremely versatile. Foldable smartphones such as the Samsung Galaxy Flip series simply wouldn’t exist without AMOLED’s physical flexibility.

OLED’s Achilles heel is that it is prone to permanent image retention or screen burn-in. This is the phenomenon where a static image on the screen can become embossed, burned-in, or simply age differently over time. Having said that, manufacturers now employ several mitigation strategies to prevent burn-in.

The AM bit in AMOLED refers to the use of an active matrix circuit for supplying current, as opposed to the more primitive passive matrix (PM) approach. The P in POLED, meanwhile, indicates the use of a plastic substrate at the base. Plastic is thinner, lighter, and more flexible than glass. There’s also Super AMOLED, which is just fancy branding for a display that has an integrated touch screen digitizer.

Even though Samsung uses the Super AMOLED branding, many of its displays use a plastic substrate too. Smartphones with curved screens would not be possible without the flexibility of plastic. Similarly, almost every POLED display uses an active matrix. The distinction between AMOLED vs POLED has diminished greatly in recent times.

In summary, OLED subtypes aren’t nearly as varied as LCDs. Furthermore, only a handful of companies manufacture OLEDs so there’s even less quality variance than you’d expect. Samsung manufactures the majority of OLEDs in the smartphone industry. Meanwhile, LG Display has a near-monopoly on the large-sized OLED market. It supplies panels to Sony, Vizio, and other giants in the television industry.

In the section on LCDs, we saw how the technology can vary based on differences in the liquid crystal layer. Mini-LED, however, attempts to improve contrast and image quality at the backlight level instead.

The backlights in conventional LCDs have only two modes of operation — on and off. This means that the display has to rely on the liquid crystal layer to adequately block light in darker scenes. Failing to do that results in the display producing grays instead of true black.

Some displays, however, have adopted a better approach recently: they divide the backlight into zones of LEDs. These can then be individually controlled — either dimmed or turned off completely. Consequently, these displays deliver much deeper black levels and higher contrast. The difference is immediately apparent in darker scenes.

This technique, known as full array local dimming, has become ubiquitous in higher-end LCD televisions. Until recently, though, it wasn’t viable for smaller displays like those found in laptops or smartphones. And even in larger devices like monitors and TVs, you run the risk of not having enough dimming zones.

Enter mini-LED. Like the title suggests, these are significantly smaller than the LEDs you’d find in conventional backlights. More specifically, each mini-LED measures just 0.008 inches or 200 microns across.

Mini-LEDs allow display manufacturers to increase the number of local dimming zones from a few hundred to several thousand. As you’d expect, more zones equals granular control over the backlight. Their smaller footprint also makes them perfect for smaller devices like smartphones, tablets, and laptops. Finally, the abundance of LEDs also helps to boost the overall brightness of the display.

Tiny, bright objects against a black background look much better on a mini-LED display as compared to one with conventional LED backlighting. However, the contrast ratio still isn’t in the same ballpark as OLED.

Take the 2021 iPad Pro, for example. It was among the first consumer devices to adopt mini-LED technology. Even with 2,500 zones across 12.9 inches, however, some users reported blooming or halos around bright objects.

Still, it’s not hard to see how mini-LEDs can eventually deliver better contrast than conventional local dimming implementations. Furthermore, since mini-LED displays still rely on traditional LCD technologies, they aren’t prone to burn-in like OLEDs.

Quantum dot technology has become increasingly common — usually positioned as a key selling point for many mid-range televisions. You may also know it by Samsung’s marketing shorthand: QLED. Similar to mini-LED, however, it isn’t some radically new panel technology. Instead, quantum dot displays are basically conventional LCDs with an additional layer sandwiched in between.

Many older display types are capable of fully covering the decades-old standard RGB (sRGB) color gamut. However, the same cannot be said for wider gamuts like DCI-P3. Coverage of the latter is important because that’s the color gamut predominantly used in HDR content.

When combined with traditional LCD color filters, quantum dot displays can cover a greater percentage of the visible light spectrum. Put simply, you get richer and ore accurate colors — enough to deliver a satisfactory HDR experience. And since the crystals emit their own light, you also get a tangible bump in brightness compared to traditional LCDs.

However, quantum dot technology does not improve other pain points of LCDs such as contrast and viewing angles. For that, you’d have to combine quantum dots with local dimming or mini-LED technologies. Samsung’s high-end Neo QLED TVs, for example, combine QLED with Mini-LED tech to match OLED’s deep blacks.

Quantum-dot OLED, or QD-OLED, is an amalgamation of two existing technologies — quantum dots and OLED. More specifically, it aims to eliminate the drawbacks of both traditional OLEDs and LCD-based quantum dot displays.

In a traditional OLED panel, each pixel is composed of four white sub-pixels. The idea is rather simple: since white contains the entire color spectrum, you can use red, green, and blue color filters to obtain an image. However, this process is rather inefficient. As you’d expect, blocking large portions of the original light source leads to significant brightness loss by the time the image reaches your eyes.

Modern OLED implementations combat this by leaving the fourth sub-pixel white (without any color filters) to improve the perception of brightness. However, they still usually fall short in terms of brightness, especially against high-end LCDs with larger backlights.

QD-OLED, on the other hand, uses a completely different subpixel arrangement — these displays start with blue emitters instead of white. And instead of color filters, they use quantum dots. In the previous section on QLED, we discussed how quantum dots are capable of producing extremely specific shades of green and red. The same property comes into play here as well. Put simply, quantum dots convert the original blue light into various colors instead of destructively filtering it, preserving the display’s overall brightness.

According to Samsung Display, another advantage QD-OLED brings to the table comes in the form of better color accuracy. Since these displays don’t have a fourth white sub-pixel, color information is rendered correctly even at higher brightness levels. Finally, quantum dots allow displays to achieve higher color gamut coverage and offer wider viewing angles than color filters.

However, it’s still early days for the technology as a whole. Traditional OLEDs have enjoyed a nearly decade-long head start yet remain relatively unaffordable. It remains to be seen if QD-OLED televisions and monitors can compete in terms of price and durability, especially considering the risks of image retention or burn-in with organic compounds.

MicroLED is the newest display type on this list and, as you’d expect, also the most exciting. Put simply, microLED displays use LEDs that are even smaller than those used in mini-LED backlights. While most mini-LEDs are around 200 microns in size, microLEDs are as small as 50 microns. For context, human hair is thicker than that at 75 microns.

Their small size means that you can build an entire display out of microLEDs alone. The result is an emissive display — much like OLED, but without the drawbacks of that technology’s organic component. There’s no backlight either, so each pixel can be turned off completely to represent black. All in all, the technology delivers an exceptionally high contrast ratio and wide viewing angles.

Brightness is another aspect in which microLED displays manage to surpass existing technologies. Even the highest-end OLED displays on the market today, for instance, top out at 2,000 nits. On the other hand, manufacturers claim that microLED can eventually deliver a peak brightness output of 10,000 nits.

Finally, MicroLED displays can also be modular. Even some of the earliest demonstrations of the technology had manufacturers creating giant video walls using a grid of smaller microLED panels.

Samsung offers its flagship The Wall microLED display (pictured above) in configurations ranging from 72 inches all the way to 300 inches and beyond. With a million-dollar price tag, though, it is clearly not a consumer product. Still, it offers a glimpse into the future of televisions and display technology in general.

It’s almost certain that microLED displays will become more accessible and cheaper in the coming years. After all, OLED is only a decade old at this point and has already become ubiquitous.

And with that, you’re now up to speed on every display technology on the market today! Display types can vary significantly and the best option depends on the characteristics you deem important or require the most.
