LG Display unveiled FLiPP (FMM-less Innovative Pixel Patterning), a photolithography-based OLED manufacturing process that replaces the fine metal mask (FMM) stencil used for 25+ years. Tested in identical conditions, FLiPP enables OLED panels that are 1.6 times brighter, 2.4 times longer-lasting, and consume 13% less power, thanks to a 55% improvement in aperture ratio—the light-emitting area of each pixel. LG has already produced a full 8.5-generation mother glass (2,200×2,500 mm) panel using FLiPP without dividing the substrate, delivering 64% higher material utilization versus FMM.
The key breakthrough is scalability: FLiPP uses UV photolithography to etch away unwanted organic material after depositing all RGB pixels in order—a process adapted from semiconductor manufacturing. Unlike FMM, which requires a new custom mask for each panel size and resolution, FLiPP can theoretically produce displays from 1 inch to 100 inches on one production line. LG plans to invest ₩3 trillion (≈$2.15 billion) and begin volume production by late 2027, initially targeting IT products (tablets, monitors) before expanding to wearables and TVs.
For display architects and AI system designers, FLiPP matters because the efficiency gains—especially 13% power reduction and 2.4× lifespan—directly cut inference costs on edge displays and reduce thermal load. The ability to use undivided substrates also means lower manufacturing waste, lower cost, and faster time-to-shelf. Competing maskless processes (Japan Display's eLEAP, China's Visionox) have faced commercialization delays; LG's Gen 8.5 full-substrate success is the first credible scaling path for RGB OLED TVs, not just smartphone displays.
