LG Display has received this year's Patent Technology Award for its technology that reduces the bezel of organic light-emitting diode (OLED) TVs by approximately 34%. By improving circuit structure, the company has enhanced both product design and production efficiency, achieving a cumulative cost improvement effect of about 385 billion won.
On November 10, LG Display announced that it won the Grand Prize, the Sejong the Great Award, at the '2026 Patent Technology Awards' ceremony organized by the Korean Intellectual Property Office for its 'High-Integration Gate Driving Circuit Patent for OLED TVs.'
This patent involves a technology that improves the structure of the gate driving circuit (GIP) that controls the pixels of the OLED panel. The GIP is located at the edge of the screen and transmits signals to the pixels. By reducing the area occupied by the circuit, the bezel can be made thinner.
LG Display has integrated parts that were redundantly used in the existing circuit into a common circuit, reducing the number of transistors by 74%. The area of the driving circuit has also been reduced by about 40%. As a result, the bezel width of a 65-inch OLED TV has been decreased from 6.5 mm to 4.3 mm.
The reduction in bezel size not only enhances the immersive experience of the screen but also increases the integration of internal panel circuits, improving manufacturing efficiency.
This technology was patented in 2020 in South Korea, the United States, Germany, and China. Since 2022, LG Display has applied it to all OLED TV panels ranging from 42 to 97 inches, achieving cumulative production of 28.3 million units to date.
Since last year, the application range has been expanded to high-performance gaming monitor OLED panels. The strategy is to enhance product competitiveness by extending the circuit design technology secured from OLED TVs to the monitor market.
Shin Hong-jae, the lead inventor and a researcher at LG Display, stated, "We will continue to secure technological competitive advantages and strive for market differentiation through ongoing research and development."
