Japan's JOLED has developed the world's first 65-inch printed OLED screen

Japan’s JOLED company (formed by the integration of Panasonic and Sony’s OLED business) used its own printing technology to develop a printed 65-inch OLED screen for the first time in the world.

JOLED has jointly trial-produced the product with China Star Optoelectronics Technology Co.Ltd. (CSOT), a subsidiary of China TCL, which will start a capital business cooperation in 2020. CSOT will be responsible for mass production and sales in the future.

The maximum size of the product was 32 inches before, and this time the product has increased the size by using low-resistance copper for wiring.

The printing method that JOLED is good at is using a device similar to an inkjet printer to coat the luminescent material on the panel substrate. Compared with the evaporation method which uses an expensive mask to attach the luminescent material to the substrate, the production of the printing method equipment is simple and suitable for manufacturing large-size screens. According to survey companies and other statistics, production costs can generally be reduced by about 30%.

Screen quality: The color accuracy of the printing method is also high, which can add depth to the image. 

JOLED President Yoshishi Ishibashi said, the technology inherited from Panasonic and Sony laid the foundation for this breakthrough.

JOLED was established in 2015 under the leadership of the Japanese government, with the goal of developing OLED screens in Japan, but the company's performance has been in a downturn. Although JOLED's factory in Ishikawa Prefecture mass-produced OLED screens by printing for the first time in the world in 2020, there will still be a final loss of 23.9 billion yen (currently about 1.214 billion yuan) in the fiscal year 2021 (as of March 2022).

In the global OLED market, South Korea's Samsung Electronics and LG Display have a high share. According to statistics from British research firm Omdia, Samsung’s share of shipments in 2021 will be 60.1%, and LG’s share will be 22.1%. JOLED hopes to use this technology to break the monopoly of Korean companies.
