LG Display has launched FLiPP, an OLED technology that eliminates the need for fine metal masks and uses photolithography to create RGB pixels.
LG Display launches FLiPP, a project aimed at producing OLED RGB panel This can provide several advantages compared to traditional processes based on Fine metal mask (FMMM). Origin of the name FLiPP “FMM-free innovative pixel pattern” and identified a system designed to eliminate the use of metal masks in the pixel pattern creation stage.
Traditional OLED manufacturing uses very thin metal masks to selectively deposit the organic materials responsible for color red, green, blue. LG Display has developed a photolithography-based process for FLiPP.
RGB materials are applied sequentially and then precisely exposed with UV light to remove unnecessary parts and allow Define pixel structure.
Advantages of LG and new technologies
According to LG Display, this approach allows Overcome some limitations of FMM. In fact, large metal masks can deform under their own weight, causing alignment issues and possible color rendering defects. Additionally, producing different photomasks for panels of different sizes and resolutions adds complexity to the production process.

One of the main advantages FLiPP focuses on Pixel apertureit is possible under the conditions indicated by LG Display Increase by about 55% Compared to panels made using FMM. This feature will help achieve superior performance in multiple aspects.
Data released by LG
The company claims brightness up to 1.6 timespanel life is long 2.4 times improvement and energy consumption 13% reduction Compared with FMM technology. In addition to these results, greater production flexibility is provided, especially when producing panels on large substrates.
In fact, FMM has the following limitations associated with it: Metal mask size When using large glass substrates. FLiPP does not rely on these components, instead allowing RGB patterns to be applied to larger surfaces.
LG Display showcases new technology Traveling to Busan during IMID 2026but has yet to announce a commercial product based on FLiPP or indicate when it might hit the market.
