Production technology of mobile phone display screen

At present, the most widely used mobile phone manufacturer is organic light-emitting diode screen, and the production process of organic light-emitting diode panel can be roughly divided into three processes: back panel section, front panel section and module section. The light-emitting structure of organic light-emitting diode is the core component of OLED panel, and its preparation process is very complicated. The production flow chart of organic light-emitting diodes is as follows:

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.

At present, among the two technical systems of organic light-emitting diodes, the technology of low-molecular-weight organic light-emitting diodes 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.

Extended data:

Organic light-emitting diode (OLED) is an organic light-emitting display, which belongs to the new product of mobile phone OLED. 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.
