OLED can be said to be a very popular term in the current display field. OLED materials have the advantages of self-luminescence, flexibility, lighter weight and lower power consumption, and can realize arbitrary folding and bending, and the application space is very broad.
In recent years, OLED display technologies have become more and more popular, especially in the small- and medium-size fields, and they are gradually eroding the consumer market. Although OLED TVs are already available in large-scale areas, in reality, due to higher production costs, the speed of adoption is far lower. In the small and medium size field.
The high cost is mainly due to the manufacturing process. Our current OLED technology relies mainly on evaporation. The principle of operation is to add solid organic raw materials to the vacuum equipment, and then heat and gasify and recondense at the specified substrate position. Formed the OLED organic layer we need.
In fact, there is another, OLED printing technology, the use of solution processing materials using printing or coating technology, instead of traditional semiconductor technology or vacuum technology to create display devices, similar to our current inkjet printers. Print display process steps Simple, the material utilization rate is more efficient than the traditional process, which can effectively reduce the production cost, shorten the production cycle, and have more advantages in the application of large-size OLED products.
Compared with traditional OLED technology, printed OLED technology is not only simpler and more precise in manufacturing processes, but it is particularly suitable for large-scale applications, and is light, thin, flexible, large-area, low-cost, and green-manufacturable. It is considered as one of the important directions for the development of the new display industry in the future.
In the field of printing and display, although the main patented technologies are still held by Japanese and South Korean manufacturers, our country has continued to carry out research and development in recent years. It is expected that by 2020, the printed display products will be mass-produced. Perhaps we After the display screen is printed out?
