Micro LED refers to LEDs with a size of less than 100 microns (the diameter of the human hair is about 100 microns), and the processing technology directly attached to the board after the substrate is removed. Most of the traditional LEDs are used for light bulbs, but the brightness is the same, but the Micro LEDs used for display are more uniform in color. Therefore, Taiwan LED manufacturers hope to use Micro LEDs to get rid of the existing LED market in the Red Sea.
The traditional LCD screen, behind it is an extra-large light box, which controls the color displayed by controlling the front LCD to control the displayed color.
However, OLED and Micro LED are self-illuminating technologies, which means that they do not need to be shielded. They can directly emit the specified color, which not only saves electricity but also makes the structure simpler. The circuits used by the two can communicate with each other, so Apple Longtan can use the same color. Group of technicians to study these two technologies.
However, Micro LED is superior to OLED because OLED is an organic material, it is easy to damage when it is in contact with water, and the yield of organic material is not easy to pull up. However, Micro LED does not have the problem of stability of organic materials, and the luminous efficiency is also three times that of OLED. The color gamut that can be expressed is also wider than OLED, and it is expected to enter mass production from a large-size screen.
