In the past, OLED has not been popularized in the market. The main problem is that most of the OLED samples developed in the early technology are mostly monochromatic. Even if the multi-color design is adopted, its color materials and production technology often limit the diversity of OLED color development. . In fact, the image generation method of OLED is the same as that of CRT display, which uses three-color RGB pixels to form a color pixel; because the OLED material reacts linearly to the current, it can display different colors and grays under different driving currents. Order. The characteristic of OLED is that its core can be very thin, and the thickness is one third of that of current liquid crystal. OLED is a solid component with good impact resistance and adaptability to harsh conditions. OLED is mainly self-learning, so there is almost no problem of viewing angle. Compared with LCD technology, the display screen is clearly visible even when observing in detail. OLED components are self-explanatory and control voltage. The reaction rate is much faster than using liquid crystal elements. It is more suitable for high-definition TV. At the end of 2007, SONY launched the 11-dimensional OLED TV XEL-1 response speed. The LCD display is 1000 times faster. Another feature of OLED is its ability to adapt to low temperatures. The old liquid crystal technology drops to minus 75 degrees, and OLED can display normally until the circuit is damaged. In addition, OLED has higher efficiency than liquid crystal, lower power consumption, and can be manufactured on substrates of various materials, and can even be changed to a flexible display, and the application range is increased. Compared with LCD, OLED is more dominant. A few years ago, the service life of OLED was still difficult to meet the requirements of consumer products (such as PDA, mobile phone, digital camera, etc.). However, there have been significant breakthroughs in recent years. Many mobile phones OLED screen has been adopted, but the price is still much more expensive than LCD, which is also waiting for breakthrough in mass production technology in the future.
