LG Display Unveils FLiPP, an FMM‑Less OLED Pixel Patterning Method

The company says the photolithography and UV‑etch process can remove mask limits on large mother glass and cut material waste, potentially lowering panel cost and raising performance.

Overview

  • LG Display unveiled FLiPP at IMID on Wednesday, presenting a new FMM‑less pixel patterning process that the company developed after about a year of focused R&D.
  • FLiPP deposits RGB materials across a full substrate and uses photolithography with ultraviolet etching to form pixels instead of fine metal masks, allowing processing of an entire 8.5th‑generation mother glass as one piece.
  • The company reported that FLiPP raises aperture ratio by about 55% and can deliver up to 1.6× brightness, 2.4× longer panel life, and roughly 13% lower power use compared with FMM panels; these figures come from LG’s demonstrations and are vendor‑provided.
  • LG has filed FLiPP trademarks and plans a phased roll‑out starting with IT panels such as tablets and monitors, with independent yield data and broad mass‑production timing still unverified and industry observers estimating scale‑up no earlier than late 2027.
  • The move places LG in direct competition with alternative FMM‑less approaches, notably TCL’s inkjet printing work, and if FLiPP meets real‑world yield and cost targets it could cut material waste, lower prices for OLED monitors and TVs, and extend product lifespans for end users.
