Boston: Phone, ho or computer companies are trying to get better displays, and a major development in this regard has been in the United States. MIT experts have created microLED pixels that can be arranged vertically instead of horizontally. Thus displays come out deeper, clearer and richer.
If you look closely at an old picture in your home, different points in it combine to make this picture. Now the finer and more the dots, the more beautiful and clear the image will be. In the same way, millions and millions of dots on a computer screen combine to form an image. Now the more pixels in less space, the brighter and clearer the display will be.
Each pixel of an OLED display is composed of three sub-pixels, including one red, one green and one blue sub-pixel. These pixels are arranged one after the other in a horizontal row. Then by emitting different colors they form a point or image. Modern displays are using micro-LEDs instead of traditional OLEDs.
According to Massachusetts Institute of Technology experts, if a micro LED pixel is reduced to just one sub-pixel, three times more pixels can be placed in the same place. This will make the quality of the display outstanding, if not revolutionary, but the MIT experts have arranged it vertically, which can increase the quality even more. So in a few years we will be able to see smartphones and TVs with extraordinary and realistic appearance.
For this, experts have created hardware in which three-color LED sheets are placed one on top of the other like layers of a cake. In the next step, it is broken down into a grid pattern, resulting in ultra-fine pixels that are only four microns wide.
In the laboratory, experts observed that just one pixel could emit rainbow-like colors and create stunning patterns. In this way, the display can be optimized by increasing the capacity of millions of pixels.
The research has been published in the journal Nature.
