LG Display wins top patent technology award for OLED TV circuit that cut bezel width 34%
South Korea's Intellectual Property Office gave LG Display its top prize for a gate driver circuit that narrowed the bezel of a 65-inch OLED TV from 6.5 mm to 4.3 mm.
South Korea's Intellectual Property Office held the 2026 Patent Technology Award ceremony on 10 November. It gave its top prize, the King Sejong Award, to LG Display for a patent on a high-density gate driver circuit for OLED TVs, according to biz.heraldcorp.com biz.heraldcorp.com

Narrower bezel, fewer transistors
For a 65-inch OLED TV, the technology reduced the bezel width from 6.5 mm to 4.3 mm, about 34%. The bezel contains the GIP gate driver circuit, and the space this circuit occupies is a main factor in how wide the bezel is. The GIP delivers the signals that control each pixel in sequence, which forms the image on the screen.
LG Display merged duplicated circuits in the GIP into a common core circuit. According to the report, this kept the display drive performance while raising the integration density of the circuit. The number of transistors in the circuit fell by 74% compared with the previous design, and the GIP circuit area fell by about 40%.
Production and application
The company says the higher integration improved the process and raised manufacturing efficiency, and that this has produced a cumulative cost improvement to date. biz.heraldcorp.com

Shin Hong-jae, a research fellow in LG Display's large display business and the lead inventor, said he was proud that long-term research had been recognized as a patent and used in actual products. He added that the company will continue research and development to build a technological moat and differentiate itself in the market.
Hong Bu-seon, who heads intellectual property at LG Display, said the company's ultra-slim bezel OLED TV panel was recognized for both technical originality and industrial competitiveness. He said the company will focus on research into prior technology and on securing key patents.
