OLED is a self-luminous material, which does not require a backlight board. At the same time, the viewing angle is wide, the image quality is uniform, the reaction speed is fast, the color is easy to be colorized, and the simple driving circuit can be used to achieve illumination, simple process, and can be made into a flexible panel. In line with the principle of light and thin, the application range is small and medium size panels.

Display aspect: active illumination, large viewing angle range; fast response, stable image; high brightness, rich color and high resolution.

Working conditions: low driving voltage, low energy consumption, and can be matched with solar cells, integrated circuits, etc.

What are the characteristics of OLED display?

Wide adaptability: large-area flat panel display can be realized by using glass substrate; if it is made of flexible material, it can be made into a foldable display. Because OLED is an all-solid, non-vacuum device, it has the characteristics of anti-vibration and low temperature resistance (-40 °C). It also has important applications in military applications, such as display terminals for modern weapons such as tanks and airplanes.

Unlike traditional LCD displays, OLED display technology eliminates the need for backlights and uses very thin organic coatings and glass substrates that illuminate when current is passed through. And OLED display screen can be made lighter and thinner, larger viewing angle, and can significantly save power.

At present, in the two major technical systems of OLED, low-molecular OLED technology is mastered in Japan, and the so-called OEL of polymer PLEDLG mobile phone is this system. The technology and patents are mastered by British technology company CDT, compared with PLED products. There are still difficulties in colorization. Low molecular OLEDs are easier to colorize. However, although OLEDs with better technology will replace LCDs such as TFTs in the future, organic light-emitting display technologies have shortcomings such as short lifetime and large screen size.
