What is an OLED screen

OLED: Organic Light EmitTIng Display, that is, organic light-emitting display, which is a newly emerging category on the LCD of mobile phones, is known as "dream display". The OLED display technology is different from the traditional LCD display method. No backlight is needed, and a very thin organic material coating and glass substrate are used. When an electric current passes through, these organic materials will emit light. And the OLED display screen can be made lighter and thinner, the viewing angle is larger, and can significantly save power.

At present, in the two major OLED technology systems, low-molecular OLED technology is mastered in Japan, and the so-called OEL of polymer PLEDLG mobile phones is this system, and the technology and patents are mastered by the British technology company CDT. Compared with PLED products There are still difficulties in colorization. Low-molecular OLEDs are easier to colorize. Not long ago, Samsung released 65530-color OLEDs for mobile phones.

However, although more advanced OLEDs will replace LCDs such as TFTs in the future, organic light-emitting display technology still has shortcomings such as short service life and difficulty in increasing the screen size. At present, OLED is mainly used by Samsung, such as the newly listed SCH-X339, which uses 256-color OLED. As for OEL, it is mainly used by LG on its CU8180 8280.
