Organic light emitting display (OLED) is a new product on mobile phone LCD, which is called "dream display".
Organic light emitting diode display technology is different from the traditional liquid crystal display mode. It does not need backlight, and uses very thin organic material coating and glass substrate. These organic materials will emit light when current passes through them. In addition, the OLED display screen can be made lighter and thinner, with a larger viewing angle, and can significantly save power consumption.
Among the two major organic light-emitting diode technology systems, the low-molecular-weight organic light-emitting diode technology is mastered by Japan, while the technology and patents of polymer PLED (the so-called OEL of LG mobile phone is the product of this system) are mastered by British technology company CDT. Compared with PLED products, colorization is still difficult.
However, although organic light-emitting diodes with better technology may replace LCD such as TFT in the future, organic light-emitting display technology still has shortcomings such as short service life and difficult screen enlargement.
The new generation of organic light-emitting diode display technology has overcome the problems of short service life (more than 30,000 hours) and difficult screen enlargement (more than 3.0 inches).
