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

OLED displays have long been manufacturer using a metal mask for deposition that wastes material, is expensive, and can sag under its own weight. LG Display's FLiPP solves this by using photolithography instead, relying on photomasks and photoresist layers to lock in the RGB subpixels.
