Abstract: The present application discloses a method for driving a display panel for displaying images. The method includes determining multiple subpixels in a bright area of an image to be displayed by the display panel. The bright area is an image display area having a luminance value maintained greater than a threshold luminance value for a duration longer than a threshold duration. Additionally, the method includes driving the multiple subpixels to emit light alternatingly in a period of alternate light-emission for displaying the image. Furthermore, the method includes driving all adjacent subpixels surrounding any one subpixel that is not emitting light during the period of alternate light-emission to provide luminance rendering to the one subpixel such that the luminance value of the bright area is greater than the threshold luminance value.
