Oled can be said to be a very hot word in the field of current display, OLED material has the advantages of self-luminous ( no backlight ), flexibility, thinner and lower energy consumption, can realize arbitrary folding bending, application space is very wide. In recent years, OLED display technology is becoming more and more popular, especially in the small and medium-sized areas, which is gradually encroaching on the consumer market. although OLED TV has been available in the large-sized areas, but in fact, due to the high production cost, the popularity rate is much lower than that in the small and medium-sized areas.
High cost, mainly due to manufacturing process problems, our current OLED technology mainly rely on vapor deposition, working principle is to add solid organic raw materials to the vacuum equipment, and then through heating gasification, in the specified substrate position to form the OLED organic layer we need.
In fact, there is another, printing OLED technology, using solvable processing materials using printing or coating technology, instead of traditional semiconductor technology or vacuum technology to make display devices, similar to our current inkjet printers. The prin display process is simple in step, that material utilization rate is more efficient than that of the traditional process, the production cost can be effectively reduced, the production period can be shortened, and the prin display process has more advantages in the application and popularization of large-size OLED products.
Compared with the traditional evaporation OLED technology, printing OLED technology is not only simpler and more accurate, especially suitable for large-size fields, but also has the advantages of light and thin, flexible, large area, low cost, green manufacturing and so on, so it is considered to be one of the important directions for the development of new display industry in the future.
In the field of printing and display, although the main patent technology is still in Japan and south Korea manufacturers, but in recent years, China is also in constant research and development, is expected to 2020, printing and display products will achieve mass production, maybe we later use the display screen are printed out?
