What could be the latest breakthrough in OLED production has just been announced, with LG Display claiming its new FLiPP production method vastly lengthens the lifespan of new panels while also increasing brightness.
FLiPP stands for FMM-less Innovative Pixel Patterning, as the new method eliminates the need of fine metal masks (FMMs) to deposit RGB pixels. FLiPP instead coats RGB pixels in order, secures them in precise positions, and incorporates photolithography — employing precision UV light etching to erase unnecessary areas during OLED pixel patterning. This allows each subpixel to sit more closely together, increasing its surface area and creating a host of benefits including an increased brightness of 1.6x and an extended lifespan.
LG Display says that eliminating the need of fine metal masks for production also saves money when it comes to panel production, meaning that the FLiPP method is also more cost-effective.
“Compared with panels produced using FMMs under identical conditions, FLiPP enables displays to increase brightness by 1.6 times, extend lifespan by 2.4 times, and reduce power consumption by 13%,” says LG. “This is because FLiPP improves the aperture ratio – the proportion of the total display area occupied by RGB pixels – by approximately 55%.”
