Currently, liquid crystal displays (LCDs) are dominant on the market. With this technology, each pixel is generated by three subpixels in the RGB colors, red, green, and blue. LEDs, which are light-emitting diodes, are here only used as white light variants as background color. Also colored LEDs can be manufactured, however, because of their size, they are only suitable for large-scale screens.
MicroLED displays are made of arrays of microscopically small red, green, and blue LEDs, where each LED corresponds to one pixel on the display. The pixels are self-luminescent, dimmable, and can be switched off completely, similar to OLED- and plasma displays, and therefore do not need any background illumination. In contrast to OLEDs, MicroLEDs are based on the gallium nitride technology, which offers a 30-times higher overall brightness as well as a higher efficiency in Lux/W and therefore a lower current consumption than OLEDs. Essential advantages of MicroLEDs are also the higher color saturation and lower sensitivity to oxygen and moisture, so that encapsulation is not required.
