Sumitomo Chemical Co. released a press release announcing that it has developed a technology for producing polymer OLED panels by inkjet method (printing method), which can produce OLED panels with a resolution of 423 ppi (using 370x470mm). The size of the glass substrate) is close to the OLED panel produced by the "vapor deposition production technology (depositing red green blue organic material on a glass substrate)".
Sumitomo Chemical pointed out that OLED materials can be applied only to the necessary places by "printing technology", so that in addition to the low-cost production of OLED panels, it can also be applied to the large size of panels, and the company will also Continuously improve the performance of polymer OLED materials and improve the process, in order to contribute to the mass production of polymer OLED panels.
Sony and Panasonic announced on June 25, 2012 that they will jointly develop next-generation OLED panels for TV/large-size displays, and the “printed†next-generation OLED technology jointly developed by the two companies will be suitable for low-cost mass production. Large-size, high-definition OLED panel technology.
It is understood that once Sony and Panasonic can establish the mass production technology of the above-mentioned "printed" OLED panel, large-size OLED panels can be produced at a cost of about half of the current liquid crystal panel (LCD), and printing technology will also be easy to be used in plastics, etc. An organic material film is formed on the film-form substrate, whereby an OLED panel having flexibility (flexibility) can be expected to be produced.
