Recently, because Apple will use AMOLED screen, the concept of OLED is a fire. The next-generation Micro-LED, which is considered to be an OLED display, does not seem to be low-key, and it is glory at the Taiwan Solid State Lighting International Symposium. Compared to OLED, Micro-LED technology is still relatively new to many people, but the focus is getting higher and higher. Today, Xiaobian explained the Micro-LED concept, advantages and disadvantages, current status and technical bottlenecks. What is wrong? Welcome to discuss the message.
What is Micro-LED?
MicroLED technology, namely LED miniaturization and matrixing technology. Refers to a high-density and small-sized LED array integrated on one chip. For example, each pixel of the LED display can be addressed and individually driven to light. It can be regarded as a miniature version of the outdoor LED display, and the pixel distance is from millimeters. The grade is reduced to the micron level.
The Micro LED display, on the other hand, uses the normal CMOS integrated circuit manufacturing process to make the LED display driver circuit, and then uses the MOCVD machine to fabricate the LED array on the integrated circuit, thereby realizing the micro display, that is, the LED display. A reduced version of the screen.

Prominent advantage
The advantages of Micro LED are obvious. It inherits the characteristics of high efficiency, high brightness, high reliability and fast response time of inorganic LED, and has the characteristics of self-illumination without backlight. It is more energy-saving, simple in mechanism and small in size. Thin and other advantages.
In addition, a major feature of the Micro LED is its high resolution. Because of the ultra-small performance, the resolution of the performance is extremely high; it is said that if the Apple iPhone 6S uses a micro LED, the resolution can easily reach 1500ppi or more, which is 3.75 times higher than the original ReTIna display of 400PPi.
Compared with OLED, the color is easier to accurately debug, has a longer luminous life and higher brightness, and has better material stability, long life, no image imprinting and the like. Therefore, another display technology with lightness and power saving advantages after OLED is common to OLEDs in that it needs to be driven by a TFT backplane, so the TFT technology grades are IGZO, LTPS, and Oxide.
