MUMBAI, India, June 20 -- Intellectual Property India has published a patent application (202414033970 A) filed by Shenzhen China Star Optoelectronics Semiconductor Display Technology Co. Ltd., Guangdong, China, on April 29, 2024, for 'driving method for display panel, driving chip, and display device.'
Inventor(s) include He, Jhenwei.
The application for the patent was published on June 20, under issue no. 25/2025.
According to the abstract released by the Intellectual Property India: "A driving method for a display panel, a driving chip, and a display device are provided. By driving sub-pixels for display across multiple frames, and ensuring each sub-pixel in every frame possesses either a high or low grayscale data compensation state, and either a positive or negative polarity, it's ensured that within the same frame, among the sub-pixels with the same display color and in the high grayscale data compensation state in two neighboring sub-pixel columns, at least one sub-pixel has a different polarity from the others. Under the Tri-Gate driving architecture, pixel polarities flip at intervals of an odd number of sub-pixels in each pixel column. This reduces polarity differences between the sub-pixels with the same display color and in the high grayscale data compensation state in four adjacent sub-pixel columns. This improves the perception of brightness changes when head movement occurs and reduces the risk of nodding lines."
