LG Display has introduced a next-generation patterning technology that eliminates the fine metal mask (FMM), a key component in traditional OLED production processes. This new technology increases the aperture ratio by 55% while reducing reliance on FMM during the pixel formation process. It is expected to enhance OLED brightness and lifespan while reducing power consumption, potentially becoming a cornerstone in the next generation of OLED competition.
On August 19, LG Display announced that it unveiled its independently developed OLED patterning technology, 'FLiPP,' at the International Meeting on Information Display (IMID) 2026, held at BEXCO in Busan.
FLiPP stands for 'FMM-Less innovative Pixel Patterning.' Unlike the traditional FMM method, this technology forms RGB pixels without a metal mask.
The FMM is a metal mask with tiny holes that is closely adhered to the OLED substrate, allowing for the deposition of red, green, and blue organic materials to create pixels. However, as display sizes and resolutions change, the need for separate FMM production increases costs.
LG Display's method involves sequentially applying RGB pixels across the entire substrate and then using ultraviolet light to remove unnecessary areas, thereby forming the pixels. This structure reduces the space between pixels and enhances luminous efficiency by not using FMM.
According to LG Display, the application of FLiPP increases the aperture ratio by approximately 55% compared to the existing FMM method. Under the same conditions, it can boost brightness by 1.6 times or extend lifespan by 2.4 times, while also reducing power consumption by 13%.
Industry experts believe that as OLED technology advances toward higher resolutions and larger sizes, the importance of process technologies that reduce FMM production costs and sagging issues will grow.
With this technology reveal, LG Display aims to differentiate not only its OLED materials and panels but also the processes used to create pixels. The company is also showcasing tandem technology and next-generation display technologies alongside large, medium, and automotive OLED products.
Additionally, LG Display introduced 'HDS,' a next-generation OLED TV panel driving technology that doubles data transmission speeds, improving the pixel driving method. This advancement has increased the refresh rate of OLED TV panels from 144Hz to 165Hz.
HDS received the 'IMID Display of the Year' award for outstanding display technology among commercial products this year. LG Display is applying HDS across all its OLED TV panel products for mass production.
At IMID, LG Display has themed its exhibition around 'OLED, the Core Technology Leading the AI Era.' The company plans to continue its technological differentiation in the premium display market by emphasizing next-generation OLED technology.
