What is MicroLED display? The great applications of MicroLED Displays in the future

MicroLED is a very popular display panel technology with the vast majority of users. However, do you really understand the application and characteristics of this type of monitor. Let’s find out with Tnhelearning.edu.vn through the article below!

What is MicroLED display?

In the display industry, the term MicroLED (flat screen panel technology) is not new, it appeared 4 years ago. MicroLED is also written under the name mLED or µLED.

MicroLED screens are screens composed of microscopic arrays of LEDs used to form basic pixels. Each of these pixels is made up of 3 sub-pixels with 3 basic colors red, blue and blue (RGB).

Compared to LCD technology, MicroLED screens offer higher contrast, higher frequency response and use less power.

Like OLED screen technology, each pixel in the MicroLED screen is capable of self-illuminating without the need for a sub-panel to illuminate underneath like LCD screens.

These arrays of LEDs are placed on a TFT panel, providing power to the screen as well as controlling when the pixels are bright and when they are not. At the same time, MicroLED technology can also produce curved screens like OLED technology.

What makes MicroLED stand out from LCD and OLED?

Similar to OLED panels, microLED panels are created with the aim of consuming less energy to equip smart watches, smartphones and ultra-thin TVs. Both OLED and MicroLED have lower power consumption compared to LCD.

According to Phonearena, the OLED screen delivers truer and deeper black areas than LCD. Similarly, MicroLED displays don’t come with a backlight, and instead rely entirely on tiny LEDs, each with 3 sub-pixels that can emit their own light. This makes MicroLED also deliver excellent similarity ratios and true blacks like OLED screens.

MicroLED panels are developed on GaN (Gallium nitride) LED technology, which is different from OLED screens because it delivers 30 times more brightness than OLED. It is this that makes the MicroLED screen will not have burn-in (the appearance of blurry images when the colors are displayed for too long).

In addition, MicroLED panels also have a longer lifespan than OLED, so it is assumed that MicroLED inherits the advantages of both OLED and LCD technologies .

MicroLED screens have molecules in size from 1 micron to 100 microns (microns are also known as micrometers – the unit for measuring the size of an impurity particle, it is one millionth of a meter). Thus, we can simply understand that this is a screen with a very small pixel size, so it produces a smoother, more beautiful image and a thinner and lighter size.

Future MicroLED display application

Although it has appeared since 2014, MicroLED technology does not seem to be popular in the display industry, but only at the research level and promises to thrive in the future.

The simple reason that can be thought of is that it is difficult to manufacture and much more expensive than LCD or even OLED. In particular, when producing on a very large scale for companies like Apple, Samsung, and LG, it becomes even more difficult.

And instead of mass-producing it, Apple has taken the first steps toward bringing the technology to a smaller scale for the Apple Watch. This is an independent step for the company to get rid of its dependence on its rivals for the supply of OLED and LCD screens.

However, the cost as well as the difficulty of mass production made the development of this technology more sluggish.

With great potential for image improvement and ultra-thin displays, MicroLED technology is always on the radar of the industry giants.

According to analysts, enough time for microLED to receive a lot of attention and interest, ready for mass production is about 4 to 5 years. Even then, the prices of products with this technology are still sky-high.
