[E-Daily Reporter JAEMIN SONG ] LG Display received this year’s Best Patent Technology Award for its circuit design technology that reduces the bezel width of organic light-emitting diode (OLED) TVs by approximately 34%.

LG Display announced on the 10th that it received the Daesang, the King Sejong Award, at the “2026 Patent Technology Awards” ceremony hosted by the Korean Intellectual Property Office for its “Patent for High-Density Gate Drive Circuits in OLED TVs.”

The Patent Technology Daesang recognizes outstanding inventions that contribute to strengthening industrial technology competitiveness. The awards evaluate patents registered with the Korean Intellectual Property Office within the last 10 years based on their technical and industrial achievements.

The core of the award-winning technology lies in improving the circuit structure that drives the OLED TV panel’s display, thereby reducing the space occupied by the bezel. The bezel area of a TV panel houses the Gate-in-Panel (GIP) circuits that control each pixel. Since pixels operate sequentially based on signals transmitted by the GIP, the circuit area is one of the key factors determining the bezel width.

LG Display independently developed a design structure that integrates circuits previously used redundantly in conventional GIPs into a common core circuit. By increasing circuit integration while maintaining screen drive performance, the company reduced the number of transistors by 74% compared to previous models and decreased the GIP circuit area by approximately 40%.

Applying this technology reduces the bezel width of a 65-inch OLED TV from the previous 6.5 mm to 4.3 mm—a reduction of approximately 34%. The company explains that the thinner screen bezel allows for a more distinctive product design and enhances the viewer’s immersion in the screen.

The technology has also yielded improvements in manufacturing efficiency. By increasing circuit integration and simplifying the production process, LG Display has achieved cumulative cost savings of approximately 385 billion won to date.

Patent applications for this technology were filed in 2020 in South Korea as well as major countries such as the United States, Germany, and China. LG Display has applied the technology to all OLED TV panels ranging from 42 to 97 inches since 2022, with cumulative mass production reaching 28.3 million units to date. Since last year, the company has been expanding the application to OLED panels for high-performance gaming monitors.

Shin Hong-jae, a research fellow at LG Display’s Large-Size Business Division and the lead inventor, said, “I feel a great sense of fulfillment that the results of our long-term research have been recognized through a patent and applied to actual products,” adding, “We will strive to differentiate ourselves in the market by building a technological moat that transcends current limits.”
