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.
The main benefit of FLiPP is how it increases the subpixel surface area in an OLED stack. Instead of the metal mask taking up space, the subpixels are spread out much closer to each other, which improves their "aperture ratio" by up to 55%. In reality, that translates to 1.6x brighter panels with 2.4x longer lifespans. Since the panel doesn't have to work as hard to drive the pixels, its power consumption drops by 13% as well.
