LG’s FLiPP Tech Could Finally Solve OLED Burn-In And Dim Screens
LG Display has unveiled a breakthrough manufacturing process dubbed FLiPP (FMM-Less innovative Pixel Patterning) that eliminates fine metal masks that have constrained OLED display production for over a decade. Could this be the end of dreaded burn-ins?
Essentially, FLiPP bypasses the traditional fine metal mask (FMM) construction whereby a stencil-like process in which red, green, and blue organic materials are evaporated through tiny physical apertures in metal sheets. Conventional FMM production suffers from significant mechanical limitations: mainly, physical metal masks tend to sag under their own weight when scaled to larger dimensions, causing alignment errors, color mixing defects, and severe panel size constraints. Furthermore, whenever a manufacturer alters panel dimensions or resolution, expensive new custom metal masks must be fabricated, driving up expenditure and reducing operational flexibility.
What FLiPP does is replaces said masks with precision photolithography via ultraviolet light etching to sequentially deposit and lock RGB subpixels into...
