The surface of the substrate is etched to form a cone shape and improve reflectivity. In addition, by forming an AlN Buffer layer, uniform crystal growth and a smooth surface can be achieved.
The EPI layer is formed by MOCVD and the transparent electric film (ITO) is formed by sputtering.
When processing ITO films, particle control is very important.
When the ITO film is formed by sputtering, negative ions accelerated in the electric field near the TG surface are incident on the substrate at a high speed, causing damage to the ITO film on the substrate. LVS is a method of lowering the sputtering voltage (negative ion acceleration electric field) and forming an ITO film in a low-damage manner.
The surface of the substrate is etched to form a cone shape to improve the light reflection efficiency.

The 8 inch displays might be affected and delay for an accident.
New iPhone 13 Series will use On-Cell OLED Displays. And it that will be launched in the second half of this year will be exclusively supplied by Samsung Display (SDC)
This is the project management of how sinocrystal handle your customized project relate to displays.
Speaking of liquid crystal display we must not be unfamiliar, but when it comes to industrial LCD Display may not have contact, with the continuous development of industry, the traditional ordinary LCD Display can not meet the requirements of the industrial industry, so there is an industrial control LCD Display, today I take you to understand the characteristics of the industrial LCD Display.
Now the application areas of LCD screens are becoming more and more widespread, often used for television and computer screen display, for different applications, LCD displays are also different, so what are the types of LCD displays?
LCD display usually have 2 types: positive display & negative display, Today we will take the following segment LCD as an example, to introduce the difference between these 2 types of display.
The Use And Maintenance of LCD Display Module
