LG Display introduces new OLED deposition technique that uses lithography instead of metal masks — "FLiPP" photolithography delivers 1.6x brightness and 2.4x longer lifespan
LG Display has just unveiled perhaps the biggest innovation in OLED manufacturing in a while, aptly called "FLiPP" or FMM-less Innovative Pixel Patterning. FMM stands for Fine Metal Masks, and they're required as a stencil to deposit organic LEDs onto a glass substrate. FLiPP gets rid of these and instead relies on photolithography to vaporize unneeded areas from an RGB subpixel to produce a brighter panel that takes less power to drive and is ultimately cheaper to produce.
