  • Patent number: 11942054
    Abstract: A driving method of a display device and a display device are disclosed, the driving method including: detecting current pixel inversion mode; determining pixel polarities and first data signals for a next frame based on pixel polarities of a current frame and the inversion mode; determining whether the next frame is an overload image based on pixel bright-or-dark values and grayscale values corresponding to the next frame and those corresponding to the overload image; when the next frame is an overload image, modifying a pixel polarity order corresponding to the first data signals, and generating and outputting second data signals to drive the display device to display the next frame; otherwise outputting the first data signals to drive the display device to display the next frame. The pixel polarities corresponding to the first data signals are in a different order than those corresponding to the second data signals.
