TCL science and technology in the investor interactive platform, said the company’s 6-generation line OLED products and the world’s major phone brand factory have mass production cooperation, is expected to print OLED in 2024 to achieve small batch mass production.
Printing OLED is an inkjet printing technology, the three primary colours of coloured light-emitting semiconductor materials as inkjet materials and ink droplets will be sprayed onto the substrate at the designated location of direct patterning, the material utilization rate of about 90%, and is not subject to the limitations of the equipment and the large size of the fine metal mask plate.
Previously, China Optical and Optoelectronic Industry Association Liquid Crystal Branch Executive Vice President and Secretary General Liang Xinqing said in an interview that TCL Huaxing has made great progress in printing display technology through strategic cooperation with JOLED in the past few years, and is fully capable of taking the lead in realizing the industrialization of printing display in China.
From the industry manufacturers and supply chain upstream and downstream news, China’s printing OLED mass production technology has basically matured. According to the relevant industry sources to confirm, at present the domestic panel enterprises have completed the 274PPI with no colour mixing, no defects in the development of printing samples, yield and other mass production has been confirmed.
At the same time, high-precision printing technology is also being developed and verified, and it is expected that the resolution of the printing technology will exceed 300PPI next year, which can correspond to small and medium-sized OLED products, and become the OLED technology that can cover full-sized products.
