TCL announced “Establishing large-area OLED panel production plant”, is solution processed RGB OLED mass production accelerated?

China TCL will invest RMB 42.8 billion (US$ 6.71 billion) in Shenzhen to establish a factory for large-area OLED panel production. According to South China Morning Post, TCL recently announced that it will produce 90,000 units on the basis of 70-inch panel in the new production line of Gen 11 (3370 mm x 2940 mm) with the goal of mass production in March 2021 in the data submitted to the Shenzhen Stock Exchange. The main products are to be known as 65-inch and 75-inch OLED panels, and 65-inch, 70-inch and 75-inch display panels with 8K resolution.

TCL will form a partnership with the China Development Fund for the necessary financing and will set up a new production line at TCL’s semiconductor subsidiary with RMB 20.3 billion.

Large-area OLED to be produced by TCL is expected to adopt solution process RGB. At the ‘4th OLED Korea conference’ hosted by UBI Research in March, James Lee, deputy chief engineer of TCL mentioned about the development of next-generation premium TV with the screen size of 70-inch or more and 8K resolution, based on the solution process.

Lee said, “The price difference between OLED TV and premium LCD TV is estimated to be reduced to 1.4 times when the price of large-area OLED panel is lowered by the operation of LG Display’s Gen 10.5 plant in 2020. We are developing solution process technology for large area OLED and it will be applicable to Gen11 factory. ”

Gen 11 production line is capable of producing six sheets of 75-inch OLED panels, being able to achieve a yield three times higher than Gen 8.5 production line and a cutting efficiency of over 95%. In addition, it is possible to produce large-area OLED panels with a real RGB structure instead of the WRGB structure when solution process is applied. Based on this, TCL emphasized that the construction of the Gen 11 solution process OLED mass production line is essential. Meanwhile, TCL has jointly established JUHUA Printing Display Technology with Tianma, a Chinese company, in 2016 through CSOT, which is a subsidiary of TCL, and is continuously developing the inkjet printing process by a Gen 4.5 R&D pilot plant.
