New type of LEDs will increase the resolution of displays three times

Joint work of scientists from severaluniversities in the world led to the fact that they were able to create LEDs that can independently change their color. This seemed impossible, since the hue of LED lamps directly depends on the semiconductor material used in it, but thanks to the new composition they began to change color depending on the electrical voltage applied to them. A new discovery may be the basis for creating displays with previously unimaginable resolution.

Many could think that LEDs have long beencan transfuse themselves in different colors - otherwise how can you explain the fact that many “smart” lamps change their shade so easily? The fact is that inside them there are a lot of red, blue and green LEDs. The radiation from these three types of LEDs is mixed in a different ratio, and due to this the lamp can take on purple, orange and other colors.

LCD work in the same way.displays, each pixel of which is created using three tiny LEDs. All of them, of course, take up space and if they could be replaced with a single LED, manufacturers would be able to create a completely new type of display with a three-fold increased resolution. Thanks to the new composition of LEDs it is quite possible.

The novelty consists of two chemical elements: rare earth europium and gallium nitride. They allow you to change the color of the LED on the fly, due to the change in the intensity of the supplied current. It is believed that reducing the number of LEDs from three to one, manufacturers can significantly reduce the cost of their devices. It is noteworthy that it will be almost impossible to see the pixels on TVs manufactured using the new technology.
