The OLED display is a display made using organic electroluminescent diodes. Due to the self-emissive organic electroluminescent diode, it does not need backlight source, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, wide operating temperature range, simple structure and process, etc. It is considered as the emerging application technology for the next generation of flat panel displays.
Organic light emitting display technology consists of a very thin organic material coating and a glass substrate. These organic materials emit light when electric charges pass through them. The color of the OLED light emission depends on the material of the organic light-emitting layer, so the manufacturer can obtain the desired color by changing the material of the light-emitting layer. The active array organic light emitting display has a built-in electronic circuit system so that each pixel is independently driven by a corresponding circuit. OLED has the advantages of simple structure, self-illumination without backlight source, high contrast, thin thickness, wide viewing angle, fast response, flexibility for use in panels, wide temperature range, etc. Technology provides the best for viewing photos and videos. Ways and less restrictions on the design of the camera.
