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.

What constitutes a great phone display? Is it the high resolution and pixel density? Well, that, and great screen quality test numbers, that"s why the Sony Xperia 1 IV specs with the 1644p 4K panel top our list. What about the high brightness and contrast that offer good outdoor visibility in the sun outdoors? That"s certainly important, but most of today"s flagships have HDR-certified panels that breach the 1000-nit barrier upwards to fit the standard, and their OLED tech ensures practically infinite contrast ratio, so it"s hard to pick on that merit alone.

Ditto for credible color gamut presentation, as per-unit display calibration is no longer a prerogative of Apple"s iPhones, while said HDR display flagships now cover both the standard RGB, and the wide P3 color gamut. Is it the actual white balance and DeltaE numbers then? It"s getting warmer, but throw in dynamically-adjusted refresh rate based on the content displayed, and you"ve narrowed it down to only a few choices when it comes to the best phone displays that we round up below.

Not only does Sony make the only phones with 4K display resolution, but it also calibrates them to a near perfect level. The flagship Sony Xperia 1 IV carries a 6.5" 4K display with the whopping 643 PPI pixel density, and our display benchmarks returned class-beating brightness, white balance and wide gamut color representation credibility levels, some of the best we"ve measured. Add the high dynamic refresh rate, and the Sony Xperia 1 IV has probably the best panel on a phone so far.

The CIE 1931 xy color gamut chart represents the set (area) of colors that a display can reproduce, with the sRGB colorspace (the highlighted triangle) serving as reference. The chart also provides a visual representation of a display"s color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The "x: CIE31" and "y: CIE31" values in the table below the chart indicate the position of each measurement on the chart. "Y" shows the luminance (in nits) of each measured color, while "Target Y" is the desired luminance level for that color. Finally, "ΔE 2000" is the Delta E value of the measured color. Delta E values of below 2 are ideal.

The Color accuracy chart gives an idea of how close a display"s measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.

The Grayscale accuracy chart shows whether a display has a correct white balance (balance between red, green and blue) across different levels of grey (from dark to bright). The closer the Actual colors are to the Target ones, the better.

Pay attention to that "brightest" part and the 1Hz-120Hz specs at the full 1440p resolution. Yes, that means that the S22 Ultra is equipped with the newest LTPO OLED display technology that allowed for both the record 1750nits of peak brightness, 15% less battery consumption than what"s on the S21/S21+, and the dynamically-allocated refresh rate that can go down to 1Hz when you are looking at static images, or rev up all the way to 120Hz when you scroll.

This brightness is what makes the S22 Ultra display, in particular, stand out, as the granularly adaptive refresh rate has been on Oppo and OnePlus phones before it.

If you are looking for the best foldable phone display, it"s again Oppo that delivers with its Find N line, rather than Samsung. We tested the Find N2"s display to be one of the most color-credible panel among all phones, not only bendy ones, and the brightest on a foldable phone.

As usual with Oppo, ever since its partnership with Pixelworks, there is a per-unit factory Delta E calibration, color-blindness presets, and camera-to-display wide color management system. The LTPO panel is factory-calibrated and delivers one of the best color credibility Delta measurements we"ve ever taken, with only Google"s Pixels being better here.

Moreover, the Find X5 Pro has the best white balance score, nearest to the 6500K reference point that means the screens colors are spot on in terms of warmth, neither too yellowish, nor cold and blueish. Adding the high typical or peak brightness levels, the company has managed to beat its own best phone displays record.

To take full advantage of its excellent display panel"s abilities, the Find X5 Pro employs a "multi-brightness color calibration," meaning that the screen is as color-credible in all lighting conditions, be it on the beach or in the dark.

Google managed to catch up with factory calibration and its Pixel 6 Pro display now delivers not only one of the most feature-rich panels in the Android universe - 1440p resolution, dynamic 120Hz refresh rate, and high brightness, but it is also in the top three in terms of color representation in our display benchmark database.

Birds of a feather, the OnePlus 10 Pro and Oppo Find X5 Pro, as they sport the same 6.7" 1440p LTPO OLED panel with dynamic refresh rate and individual display calibration at the factory level courtesy of the imaging specialists from Pixelworks. Thus, you get a near-perfect color accuracy, wide gamut coverage, and high average brightness, all for less than $900 barring any running OnePlus 10 Pro deals.

These measurements are made using Portrait Displays" CalMAN calibration software.The high dynamic refresh rate is the best thing that happened to mobile displays since the introduction of the OLED technology, and there is no looking back once you"ve tried it while browsing and scrolling. Here"s the answers on our question how does it all work exactly:

The display is also basically able to do what MEMC TVs do, automatically increasing frames in video to up the rate, and take better advantage of the high refresh rate even with content that is usually shot with 24fps or 30fps. Detailing the panel"s virtues in a blog post, the OnePlus CEO also mentioned that:

In order to reach industry-leading color accuracy standards, we have added an additional automatic color calibration machine to the production line. By adding an extra 30 seconds to the production time, each display panel is automatically calibrated for color accuracy before it’s released.

Apple"s finest finally found the 120Hz refresh feature (say that 3 times quickly) and if you are already invested in the iOS ecosystem, there is nothing better than the brightest, toughest displays on an iPhone so far, the one on the iPhone 14 Pro Max and iPhone 14 Pro.

Apple advertises it as having a record for a phone peak brightness level of 2000 nits, or more typical brightness of 1600 nits when consuming HDR content and 1000 nits otherwise. This is exactly what we measured and these displays are so advanced that only Samsung can make them at the moment with its 12th-gen OLED technology.

As usual, Apple offers great individual color calibration and the Super Retina XDR panel is HDR certified to show 4K Dolby Vision HDR video recorded by the phone"s own cameras. The only ho-hum part is the just average greyscale representation, so while the iPhone 14 Pro Max may have the brightest phone screen it"s not the most accurate in terms of color credibility.

Say what you will about Google entering the fray here but the Pixels have very well calibrated displays and the new Pixel 6a is no exception. First off, its color credibility is better than the more established calibration champs here (just look at those DeltaE numbers below). It is also sufficiently bright, so if you are looking for a compact 5G Android phone with a great camera and display that won"t break the bank, the Pixel 6a would fit your narrative.
