LG Unveils Mask-Free OLED Manufacturing Process

LG has introduced a manufacturing breakthrough for OLED panels called FLiPP, or FMM-less Innovative Pixel Patterning, which removes the need for the fine metal masks (FMMs) typically used to stencil organic LEDs into pixel patterns, according to Engadget.

Traditional metal masks are expensive to produce and prone to sagging, which creates alignment challenges for larger television panels. LG's FLiPP system instead stencils RGB pixels directly onto panels and utilizes UV light and photolithography to remove unnecessary areas during the patterning process.

LG reports that this shift in production results in panels that are 1.6 times brighter and last 2.4 times longer, while cutting power consumption by 13 percent. The company also noted that the process is free from resolution and size constraints, making it applicable to devices ranging from 1-inch wearables and VR headsets to ultra-large TVs.

In practical application, LG stated that the technology allows for better utilization of mother glass—up to 64 percent higher when producing laptop panels—which reduces substrate waste and lowers manufacturing costs. LG plans to deploy the technology first in monitors and tablets before expanding to other product categories, though Engadget notes that LG has not yet provided a specific market release date.
