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.
LG Display has introduced a groundbreaking new OLED deposition technique called FLiPP, which stands for FMM-less Innovative Pixel Patterning. This innovative method replaces traditional metal masks with photolithography to vaporize unwanted areas from RGB subpixels, resulting in a brighter, longer-lasting panel that consumes less power.
By increasing the subpixel surface area in an OLED stack, FLiPP improves the aperture ratio by up to 55%, translating to 1.6 times brighter panels with 2.4 times longer lifespans. The process also eliminates the need for heavy metal masks, reducing panel uniformity and color blending issues. FLiPP's flexibility allows production of panels ranging from 1 to 100 inches for various devices and applications with any resolution in mind.
LG has already produced an OLED panel using an entire 8.5-Gen motherglass, and the company is investing 3 trillion Won, or $2.15 billion, to begin commercial production by late 2027. Laptops and monitors are expected to be the first recipients of FLiPP OLED screens, with potential applications expanding to smartwatches and ultra-large TVs.
