Displays or displays for smartphones, in general, have grown over the years. There was a time when no matter how expensive your phone was, it would have the same display technology as mid-range phones – the base LCD screen. Yes, the distinction and quality will be different, but the basic technology will be the same.

By 2022, most of your phones now have an OLED display. Not only have we seen that the separation of displays, especially in mobile phones, tablets and laptops, has increased dramatically, but we have also seen that the quality of displays has improved much over the years. Saturated and bright colors, proper ink-black, low response time, high contrast and incredible brightness – we have OLED displays, which should be thanked for all these benefits.

OLED panels have been around since the 2000s, when they were introduced to the car stereo. Later, when it became a bit mainstream, we saw it in some phones, but since it wasn’t cost effective and didn’t look at all like modern OLEDs, we soon got rid of them. After many improvements and developments, began to manage the best TVs that could be bought for money. Now display technology is returning to our phones and personal devices, albeit in three different forms – OLED, AMOLED and P-OLED.

What are OLED displays?

OLED or organic LED is a display technology that passes current through organic diodes on a glass substrate to create an image. The light-emitting pixels of the OLED display emit blue and yellow light. Yellow and blue lights combine into white light, which then passes through red, green and blue subpixels to get one pixel. Unlike LCD panels, OLED panels do not need separate backlighting. This is one of the many reasons why OLED displays consume much less power, especially when they show a dark image.

OLED displays have a deep, ink-black color and exceptionally good contrast. If the color is not displayed, no light is emitted from this part of the display. It also allows them to create an “infinite contrast” or a contrast ratio of 1,000,000: 1. This means that the darkest part of the display will be a million times darker than the brightest. It gives us bright colors and a better viewing experience.

OLED panels also have a much longer response time, which essentially means that each pixel responds to signal changes much faster than traditional IR. This is the refresh rate that manufacturers refer to. Basically, this means that the OLED panel will be able to change color 120 times per second. This gives the images you are looking at much clearer and smoother.

OLED panels also take up much less space than LCD panels because they do not use a panel for backlighting. It also makes them cheaper to manufacture. And because they do not require backlighting, OLED displays can sometimes be transparent. This allowed manufacturers to develop built-in fingerprint readers and cameras under the display.

However, OLED displays are not perfect. They are prone to much faster degradation with age and exposure to ultraviolet light. Because images and colors are very bright, you can often see remnants or “ghosts” of an image on certain parts of the screen, even if it is not displayed. This is called burnout, and it is the biggest phenomenon that makes OLED panels useless after a short period of continuous use.

OLED panels are cheaper to manufacture, but because they are very thin and fragile, in order to make them a proper display, as in a TV or mobile phone, you need to use reinforced glass or metal frames. Also, at peak brightness OLEDs consume more power than conventional IR.

What are AMOLED displays?

If you are buying a premium smartphone with an OLED display, chances are you are really buying an AMOLED display. AMOLED stands for Active Matrix OLED, and modern OLED displays found in consumer electronics use the active matrix as opposed to passive matrices found in older OLED displays.

The active matrix or thin-film transistor arrays used in AMOLED displays are more energy efficient than most older OLED displays. Samsung dominates the AMOLED display market and has named the best of the best they produce as the Super AMOLED display. AMOLED displays typically combine the benefits of P-OLED displays and conventional OLED displays. They are very durable and versatile, which means they are more expensive.

What are P-OLED displays?

P-OLED stands for Organic Polymer LED. In its most basic form, it is a twist on the modern OLED panel, which eliminates most of the disadvantages that can be obtained with an OLED panel.

P OLED displays replace glass substrates with substrates made of polymers or plastic. This makes the panel more impact resistant and less prone to breakage. Depending on the type of polymer used, P OLED displays can also be flexible, so they can be used in complex and roll devices. Because polymer sheets can be made with higher tolerances than glass, polymer OLED or P OLED displays can be much thinner.

P OLED displays have several drawbacks. They are usually not as sharp as modern OLED displays; with this in mind the difference is seldom noticeable. P OLED displays have a higher tendency to burn out
