Huaxing Optoelectronics Plans to Build an 11 Generation LCD OLED TV Manufacturing Plant, Which Will

On May 22, csot (a subsidiary of TCL) announced that it planned to build an 11 generation LCD OLED TV manufacturing plant in Shenzhen. The second 11th generation line of Huaxing optoelectronics project aims to invest in the construction of a monthly processing 3370mm & Tides in Guangming New Area, Shenzhen; The 11th generation ultra-high definition new display device production line with about 90000 2940mm glass substrates mainly produces and sells 65 inch, 70 inch and 75 inch 8K ultra-high definition displays and 65 inch OLED and 75 inch OLED displays. The total investment of the project is about 42.683 billion yuan. The project is jointly invested by TCL group, Huaxing optoelectronics and Shenzhen major industrial development fund. It is planned to officially realize mass production in March 2021.

The latest news indicates that the new plant will adopt oxide TFT backplane, and the OLED business will also use 11th generation substrate (which may be cut into actual OLED front deposition). In the capacity of 90000 substrates per month, the OLED production line will use 20000. The plant will start mass production in 2021.

It is reported that Huaxing optoelectronics is making progress in the inkjet project and cooperating with kateeva, Sumitomo chemical, Merck, DuPont and Tianma, as well as the scientific research teams of Chinese universities. It is unclear whether these groups have joined Guangdong Juhua printing and display technology company established by Huaxing optoelectronics and Tianma in 2016.

Huaxing optoelectronics believes that the ink-jet printing technology of OLED TV will be available in the next 3-5 years, which means that it can be used in the new 11th generation factory, but the factory may adopt the evaporation process at the initial stage.

At present, the production capacity of OLED panels is mainly controlled by Korean panel factories. Small and medium-sized OLEDs, represented by Samsung, mainly produce RGB OLEDs by high-temperature evaporation. At present, the process technology is relatively mature and the yield is high. Domestic panel factories have followed up with investment; In terms of large-size OLEDs, w-oleds are mainly produced by LGD through high-temperature evaporation. At present, the production cost is much higher than LCD TV panels, and the market acceptance is low. In 2017, 1.7 million OLED TV panels were shipped, accounting for less than 1% of the TV panel market. The scientific community seeks to break through the bottleneck of large-scale OLED mass production in other ways. Printing display is one of the high hopes.

The printing display uses organic, inorganic and nano materials processed by soluble liquefaction, and uses printing or coating technology to replace the traditional semiconductor technology / vacuum technology to make the display. Compared with evaporated OLED, printed OLED has the characteristics of light, thin and flexible, large area, low cost and green manufacturing. It is a revolution of industrial technology and the development direction of new display industry in the future. Samsung in Korea, joled in Japan and Huaxing Optoelectronics in China are actively developing printing and display research and development, but Huaxing optoelectronics is the first enterprise in the world to invest in printing OLED panel production line.

Industry experts predict that the printed display will reach the conditions for mass production in 2020. When the key technologies of printed display are mature and industrialized, the production cost of large screen OLED will be greatly reduced and the rapid development of large-size OLED panel market will be promoted.
