LG Display Unveils FLiPP: A Groundbreaking Evolution in OLED Technology

LG Display, a global leader in display technology innovation, made headlines recently with the announcement of its latest development, FLiPP (FMM-Less innovative Pixel Patterning). This revolutionary manufacturing method eliminates the traditional fine metal mask (FMM) process, offering significant advancements in the production of OLED panels.

A New Era for Manufacturing OLEDs

The unveiling is scheduled for the International Meeting on Information Display (IMID) 2026 in Busan, and LG Display will showcase its innovative technology over three days starting August 19. The FLiPP method addresses longstanding challenges associated with conventional FMM techniques, enhancing production flexibility, increasing panel brightness, extending lifespan, and cutting power consumption.

Compared to traditional FMM-produced displays, FLiPP panels boast an impressive increase in brightness by 1.6 times, a lifespan extension of 2.4 times, and a reduction in power consumption by 13%. This dramatic improvement is achieved by significantly enhancing the aperture ratio — the proportion of the total display area occupied by the RGB pixels — by around 55%.

Overcoming FMM Limitations

For years, the FMM approach has driven the production of OLED technology, but it comes with certain drawbacks. Each shift in panel size or resolution necessitates the creation of new expensive FMMs, and larger metal masks face structural challenges that can lead to misalignment during manufacturing. FLiPP eliminates these limitations by introducing a new paradigm in OLED production, relying on RGB pixel coating and precision photolithography techniques to create high-quality displays without the downsides of larger metal plates.

LG Display's R&D efforts culminated in the development of FLiPP as a modern solution to these obstacles. Unlike the stencil-like FMM process that involves the evaporation of organic materials through minute holes in metal plates, FLiPP coats RGB pixels sequentially and secures them in precise formation, leading to superior quality and performance.

Innovations in Efficiency and Sustainability

Thanks to its proprietary Tandem WOLED production infrastructure and experience, LG Display has become a pioneer in FMM-less OLED manufacturing using 8.5th-generation mother glass in its entirety. This new process can achieve up to 64% higher mother glass utilization efficiency compared to other methods that require divided substrates. The impact is twofold — not only is there a substantial reduction in waste material, but production output and cost efficiency are also significantly boosted.

FLiPP's versatility is another strong point. Its design is free from constraints associated with panel size and resolution, allowing for displays from a mere 1 inch to a massive 100 inches. The technology is applicable across a wide range of products, extending from smaller devices like wearables to large televisions, catering to diverse consumer needs.

Choi Young-seok, CTO of LG Display, expressed pride in achieving this 'dream technology': “We merged our proprietary WOLED technologies and expertise to materialize FLiPP. Participating in IMID helps us to cement our leadership in next-generation OLED technologies and enhance market differentiation.”

Moreover, alongside the FLiPP announcement, LG Display's advanced OLED TV technology known as Hyper Double Scanning (HDS) has also received accolades by winning the IMID
