LG Display unveiled FLiPP, a maskless OLED patterning process that eliminates fine metal masks on 8.5-generation mother glass. Debuting in August 2026 at IMID, the technology increases aperture ratios by 55 percent, boosts brightness 1.6 times, extends lifespan 2.4 times, and cuts power consumption by 13 percent.
Display manufacturing has long chased what engineers call the “dream process”—a way to pattern organic light-emitting diode displays without the physical stencils that have constrained the industry for over a decade. LG Display has broken through that barrier by introducing a proprietary technique that bypasses traditional metal plates entirely, setting the stage for commercial production targeted for late 2027.
How FLiPP Replaces Fine Metal Masks
Conventional red, green, and blue pixel production relies on fine metal masks, or FMMs. Manufacturers press a metal plate featuring microscopic holes against a glass substrate, evaporating emissive materials through those openings to form individual subpixels. While effective, the method hits severe physical limits as screen sizes scale upward. Large metal plates inevitably sag under their own weight, causing pixel misalignment, color-mixing defects, and heavy manufacturing overhead whenever a resolution or panel size changes.
LG Display’s new FMM-Less innovative Pixel Patterning process discards the metal plate by adapting semiconductor manufacturing techniques. Instead of depositing material only through mask openings, the company coats RGB emissive materials sequentially across an entire substrate and then uses precision ultraviolet photolithography to remove material everywhere except where each color’s pixels remain.
“By concentrating our proprietary technologies and know-how, we have succeeded in realizing FLiPP, long called the ‘dream technology.’ We will lead next-generation OLED technology and accelerate market differentiation.”

Measuring the Performance Gains
The removal of the metal mask alters the physical geometry of the panel. By eliminating the dead space required by mask structures, the aperture ratio—the proportion of the total screen area that actually emits light—increases by approximately 55 percent compared to conventional methods.
That expanded light-emitting surface translates directly into measurable efficiency and durability gains under identical operating conditions. According to company disclosures, FLiPP enables displays to increase brightness by 1.6 times, extend lifespan by 2.4 times, and reduce power consumption by 13%. Lower power draw generates less internal heat, which simultaneously helps mitigate the risk of thermal panel degradation and burn-in over extended use.
Manufacturing on Whole 8.5-Generation Mother Glass
Beyond pixel-level performance, the maskless technique changes how large glass sheets move through factory floors. Traditional FMM production requires dividing massive 8.5-generation and 8.6-generation mother glass substrates—measuring roughly 2,200 by 2,500 millimeters—into smaller half-cut pieces because sagging FMM sticks cannot span the entire sheet reliably.
FLiPP allows manufacturers to process an entire 8.5-generation mother glass substrate as a single piece. For laptop and monitor production, LG Display reports that this whole-glass approach achieves up to 64 percent higher mother-glass utilization efficiency compared with conventional FMM production and rival maskless processes that still rely on divided substrates.
From Wearables to Ultra-Large Displays
Because the process is free from the mechanical constraints of metal stencils, it removes traditional size and resolution boundaries. In theory, the technology can support displays ranging from 1 inch to 100 inches, opening applications across virtual reality and augmented reality headsets, wearable devices, IT monitors, tablets, and ultra-large televisions.
Initial commercial deployment will focus on IT products such as tablets and monitors before expanding across the broader display catalog.
Commercial Rollout Timelines and Industry Rivalries
Mass production is slated to begin as early as late 2027 at the earliest, meaning consumer devices featuring FLiPP panels will likely populate 2028 and 2029 product lineups.
LG is not alone in searching for mask-free production methods. Competitors have explored alternative approaches, such as inkjet printing methods for RGB displays, though scaling those techniques to massive television formats remains an ongoing engineering challenge.
