Abstract
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.
