Nikkei News reported on the 30th, Sumitomo Chemical (Sumitomo Chemical) has developed a new technology to enhance the accuracy of OLED panel light-emitting device, and through this new technology will be able to significantly reduce the cost of OLED panel manufacturing, the goal is to panel manufacturing costs It is half a cut from the current level, and this is expected to drive down the price of OLED TVs and promote their popularity.
The new technology developed by Sumitomo Chemical Co., Ltd. uses a printing method to form a polymer material for a light-emitting device and blows a material like an ink-jet printer to form a light-emitting device.
The current OLED panel manufacturing technology is based on the principle of “vapor deposition (vaporization of red, green, and blue light-emitting materials on a substrate under vacuum)â€. However, the vapor deposition technology requires high-level equipment and it is easy to waste too much. The material and cost are high; while the printing technology (the liquid luminescent material is precisely applied on the substrate like a printer) has a low cost, it is difficult to uniformly coat the luminescent material when producing a large-sized panel. According to reports, the goal of “uniform coating†can be achieved with new materials developed by Sumitomo Chemical Co., Ltd., and Sumitomo Chemical has also developed special manufacturing equipment for new materials.
The report pointed out that the new materials mentioned above were jointly developed by Sumitomo Chemical and overseas panel makers and JOLED, an affiliate of Japan Display Inc (JDI). JOLED is expected to start selling the 21.6-inch medical OLED panels this autumn, and Sumitomo Chemical will take the lead. South Korea’s LG Display (LGD) and other manufacturers will also be called upon to adopt the new technology, with the goal of mass production in 2019 and application on large-size TVs.
