LG’s FLiPP Tech Could Finally Solve OLED Burn-In And Dim Screens

A New Approach to OLED Manufacturing

LG Display has introduced a new manufacturing method for OLED panels, dubbed FLiPP (FMM-Less innovative Pixel Patterning), which the company describes as a "dream next-generation OLED" patterning method. The technology aims to overcome longstanding limitations in OLED production, potentially leading to displays that are brighter, longer-lasting, and more efficient. As reported by both Hot Hardware and The Verge, FLiPP eliminates the fine metal mask (FMM), a metal plate with tiny holes used to stencil light-emitting materials during production—a process that has constrained OLED manufacturing for over a decade.

The Problem with Fine Metal Masks

Conventional FMM-based production has faced mechanical challenges. According to Hot Hardware, these masks tend to sag under their own weight when scaled to larger dimensions, causing alignment errors, color mixing defects, and severe panel size constraints. Additionally, manufacturing adjustments require custom masks, which are expensive and reduce operational flexibility. The Verge similarly notes that the FMM process can be costly, with larger panels suffering from sagging and alignment issues.

How FLiPP Works

FLiPP replaces metal masks with photolithography, using ultraviolet light to etch and deposit RGB subpixels in precise positions. Hot Hardware explains that this method removes the dead space previously needed to hold masks in place, expanding the display's aperture ratio—the area actively emitting light—by approximately 55%. The Verge reports that FLiPP positions RGB pixels in order and then uses UV light to remove unnecessary areas.

Claimed Performance Gains

Both outlets report LG Display's claims that FLiPP panels, when tested against FMM panels, achieve a 1.6 times boost in peak brightness, a 2.4 times extension in operational lifespan, and 13 percent lower power consumption. Hot Hardware adds that the more efficient light emission generates less heat during operation, which could substantially mitigate long-term image retention and burn-in risks. The Verge quotes LG Display as saying the method is "free from panel size and resolution constraints," making it suitable for virtual reality and augmented reality displays.

Manufacturing Efficiencies and Product Plans

Hot Hardware highlights additional manufacturing benefits. FLiPP is described as the industry's first process capable of patterning RGB OLEDs on an uncut, whole 8.5th-generation mother glass substrate. Using whole mother glass improves substrate utilization efficiency by up to 64% compared to divided-substrate methods. The technology can reportedly produce displays ranging from 1-inch wearable screens up to 100-inch television panels.

Both sources report that LG Display will initially apply FLiPP to "IT applications" such as tablets and monitors, before expanding to ultra-large TVs and 1-inch wearable devices. Hot Hardware adds that the company has secured global trademark filings and presented working prototypes at the IMID show in Busan. Neither outlet provided information on when production will begin or when the first consumer products will be available.
