LGD OLED TV ultra-slim bezel technology patent technology award grand prize

LG Display announced on the 10th that it received the grand prize, the King Sejong Award, for the 'organic light-emitting diode (OLED) TV high-integration gate driving circuit patent' at the '2026 Patent Technology Award' ceremony held by the Ministry of Intellectual Property.

The Patent Technology Award is given to excellent invention technology among patents registered with the Intellectual Property Office within the past 10 years.

LG Display's OLED TV highly integrated gate driving circuit patent is an innovative circuit structure design technology that dramatically reduces the bezel size of the OLED TV screen. Patents were applied for in Korea and major overseas countries such as the United States, Germany, and China in 2020.

The bezel part of the TV panel has a GIP (gate in panel), a driving circuit that controls each pixel. Each pixel is controlled sequentially according to the signal transmitted by the GIP, and the image is displayed on the screen. The space occupied by the GIP circuit is one of the main factors that determines the width of the TV bezel. As this space is reduced, a thinner bezel can be realized.

LG Display developed its own design structure that integrates circuits used repeatedly in existing GIPs into a common core circuit and applied for a patent. Through this, the degree of circuit integration was increased while maintaining stable screen driving performance. As a result, the number of transistors that make up the circuit was reduced by 74% and the GIP circuit area was reduced by about 40% compared to the previous version.

If this technology is applied, the bezel width for a 65-inch OLED TV will be reduced from the existing 6.5 mm to 4.3 mm, or about 34%. As the bezel at the edge of the screen becomes thinner, the product design becomes neater and screen immersion increases, improving the completeness of the product.

This patent also contributed greatly to productivity innovation. As a result of improving the process and increasing manufacturing efficiency by increasing circuit integration, the cumulative cost improvement effect of approximately 385 billion won has been achieved to date.

LG Display has been applying this technology to all 42- to 97-inch OLED TV panel products since 2022 and has achieved a cumulative mass production of 28.3 million units. Since last year, the scope of application has been expanded to include OLED panels for high-performance gaming monitors.

Shin Hong-jae, a research fellow at LG Display's large division and the main inventor of this technology, said, "Through continuous research and development, we will build a technological moat that goes beyond limitations and strive to differentiate ourselves in the market."
