Silicon Based OLED: The Most Suitable Micro Display Technology for The near Eye Display Industry
2023-07-08
Silicon-based OLED microdisplay is an active organic light-emitting diode display device which combines CMOS technology and OLED technology and uses monocrystalline silicon as an active driving backplane. The mono-crystal silicon chip adopts mature integrated circuit CMOS technology, and combines the outstanding advantages of OLED fast response, large viewing Angle, low power consumption, etc., not only realizes the active addressing matrix of display pixels, but also realizes the drive control circuit of various functions such as SRAM memory, T-CON, and so on, reducing the external connection of the device. The reliability is increased, the lightweight is achieved, the pixel size is 1/10 of the traditional display device, and the precision is higher than the traditional device.
Silicon-based OLED is an important branch of active organic light-emitting display AMOLED. Compared with AMOLED display technology, silicon-based OLED display technology has the following outstanding features:
1)The substrate chip adopts mature integrated circuit technology, and the manufacturing yield is much higher than LTPS technology.
2) The use of monocrystalline silicon, high mobility, stable performance, high life.
3) 200mm ×200mm OLED evaporation packaging equipment can meet the manufacturing requirements, unlike AMOLED need to pursue a high generation production line.
4) Silicon-based OLED microdisplays are small in size and provide near-eye display effects that can be comparable to AMOLED displays.
The military field is the entry point of silicon-based OLED microdisplay related products in the early development stage, and the application mainly includes sighting system, helmet system and simulation training system, which is an important part of national defense modernization and information construction. Due to its high manufacturing yield, stable performance, long life, small size, low power consumption and other characteristics, it has become the main solution for wearable display such as helmet display, stereoscopic display and glasses display, and can be widely used in the field of high-resolution near-eye display such as VR/AR, industrial security, medical treatment, etc. Gradually become a new display industry wrestling point.
