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.

Abstract: The embodiments of the present disclosure disclose a gate driving circuit and a display panel. In the gate driving circuit, a control unit of a shift register may input a dual pulse control signal to a first control terminal of an output unit; and the output unit outputs a scanning signal having a pulse width equal to a pulse period of the dual pulse control signal to a corresponding gate line under the control of the dual pulse control signal. In this way, the output unit is controlled by the control unit to output a scanning signal of which a pulse width may be modulated, so as to output a gate signal of which a pulse width may be modulated.
