Will the display be printed in the future? This OLED technology is absolutely!

OLED can be said to be a very popular vocabulary in the current display field. OLED materials have the advantages of self-luminescence (without backlight), flexibility, lighter weight and low power consumption, and can realize arbitrary folding and bending, and the application space is very broad.

Will the display be printed in the future? This OLED technology is absolutely!

In recent years, OLED display technology has been popularized, especially in the small and medium-sized areas, and is gradually eroding the consumer-grade market. Although OLED TVs have been commercially available in large-size areas, in reality, due to higher production costs, the popularity is far lower. In the small and medium size field.

Printing OLED process

The high cost is mainly due to the manufacturing process. Our current OLED technology mainly depends on evaporation. The principle of operation is to add solid organic raw materials to the vacuum equipment, and then after heating and gasification, re-condense at the designated substrate position. Formed the OLED organic layer we need.

In fact, there is another kind of printing OLED technology, the use of solution processing materials using printing or coating technology, instead of traditional semiconductor technology or vacuum technology to produce display devices, similar to our current inkjet printers. The printing and display process steps are simple and 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 and popularization of large-size OLED products.

Compared with conventional evaporation OLED technology, printing OLED technology is not only simpler and more precise in manufacturing processes, but it is particularly suitable for large-scale applications, and has the advantages of thinness, flexibility, large area, low cost, and green manufacturing. It is considered as one of the important directions for the development of the new type of display industry in the future.

Printing OLED technology

In the field of printing and display, although the main patented technology is still in the hands of Japanese and South Korean manufacturers, in recent years, our country has also continued to carry out research and development. It is expected that by 2020, printed display products will be mass-produced. Perhaps we After the display screen is printed out?
