OLED is a device based on organic semiconductor materials. The materials used in OLEDs are small molecules and macromolecules. At present, industrialization mainly uses small molecular organic materials. It is currently widely used in mobile devices and even on television. It has ultra-fast response speed and light weight advantages, simple manufacturing process and lower cost. It can be fabricated on different materials and can be made into a flexible display that can be bent.
In addition, because OLED is an all-solid, non-vacuum device, it has anti-vibration, low-temperature resistance and other characteristics, and also has important applications in the military.
However, OLED displays have the disadvantages of longevity and insufficient support for large sizes. On the whole, the industrialization of OLED has begun. Monochromatic, multi-color and color devices have reached mass production levels. Large-size full-color devices are still in the research and development stage, but the production capacity is still low.
OLED display has self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, flexible panel, wide temperature range, simple structure and simple process. It is considered to be the next generation of flat panel display emerging application technology.
