LG Display announced that it will build a technological barrier that competitors will find difficult to overcome by promoting its next-generation organic light-emitting diode (OLED) manufacturing technology, “FLiPP.”

Chief Technology Officer (CTO) Youngseok Choi of LG Display said at the online “FLiPP Tech Seminar” held on the 8th, “FLiPP is the greatest process innovation in the existing 8th generation, and it will serve as a moat—a technology that the display industry finds challenging and intimidating to pursue.”

FLiPP is a technology that eliminates the fine metal mask (FMM), an ultra-precise metal mask used when depositing red, green, and blue (RGB) emitting materials onto OLED panels. FMM is a thin metal plate perforated with microscopic holes, and FLiPP instead uses light to form pixels with precision. By removing the metal plate, the distance between pixels is reduced, enabling screen luminance to increase by 1.6 times compared with existing methods or product lifetime to extend by 2.4 times. Power consumption can also be reduced by 13%.

Production efficiency has also been improved. Under the conventional 8th-generation FMM method, the sagging of the metal plate required cutting the large glass mother substrate in half, but FLiPP allows the substrate to be used intact without cutting. As a result, panel production efficiency per mother substrate has increased from 75% to more than 93%. The utilization efficiency of organic materials has improved from 40% to 74%, and deposition process time has been shortened by 40%.

LG Display plans to first apply FLiPP to panels for tablets and notebooks, and then expand its use to wearable devices and ultra-large TVs.
