People may have become accustomed to LCD screens on mobile phones, computers, and televisions. Recently, a black technology display is gradually appearing in the eyes of the public and has the tendency to subvert LCD screens. It is a new generation of display material, OLED screen, which has many advantages such as being thinner, flexible and bendable. Like the LCD screen instead of the heavy CRT display technology, the rise of OLED will bring about the same impact, but this time may be mild. What is OLED screen Organic Light Emitting Diodes (OLEDs) or Organic Light Emitting Diodes (OLEDs) are new display technologies developed in the mid-20th century. The core is still in Light EmitTIng Diode, which is LED. Although LEDs are more common in daily life, each LED is very small in size on the screen and is divided into three sub-pixel groups of red, green and blue, and then forms a different color, and the arrangement of sub-pixels is different. The mode will also affect the entire display. The principle is that after the organic semiconductor thin film is injected by the positive load flow, light is generated by the composite. The first is the backlight module of the LCD panel. The backlight module accounts for 20% to 30% of the cost of small and medium size LCD panels, and can account for 50% of large size LCD panels. The global market is about 18 billion U.S. dollars. Since traditional LCD panels must use external backlights, and OLEDs are self-emission technologies, they do not require backlight modules. If OLEDs are used in large numbers to replace liquid crystals, then backlight modules will include a large number of reflective films, brightness enhancement films, and diffusions used in backlight modules. Optical films such as films form a strong impact. OLEDs are self-emissive materials, do not need to use backlight panels, and have a wide viewing angle, uniform image quality, fast response, easier colorization, simple light-emitting circuit, simple process, and flexible panels. In line with the principle of thin and light, the scope of application belongs to small and medium size panels. From the CRT era to the LCD era, domestic companies have been thrown away by Japanese and South Korean companies for a long distance. The LCD panel industry, represented by BOE, has been playing the role of a chaser, spending huge amounts of money, and LCD panels have been chasing the fourth-generation line. To the tenth generation line. In the OLED era, South Korean companies are now in the leading position, and Chinese companies have begun a new round of catch-up, but this time the gap does not seem to be as big as last time.
