Abstract

The invention discloses a display panel picture improvement method and device, a server and a memory; the method comprises the steps: obtaining and judging the target number of target pixels in a preset gray scale range in a gray scale histogram corresponding to a frame image which is not outputted and displayed in two adjacent and matched frames of images to be displayed of a display panel; and judging whether one frame of image which is not output and displayed meets a frequency reduction condition or not according to the target number, if so, reducing the display frequency of the image, and outputting the frame of image after the display frequency is reduced. According to the display panel picture improvement method provided by the embodiment of the invention, the output display frequency of the matched two adjacent frames of images is reduced while picture flicker of the display panel is avoided, and the power consumption of the display panel is reduced.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method, device and memory for improving the picture of a display panel. Background technique [0002] With the development of display technology, people have higher and higher requirements on the appearance of display screens. Among them, in order to pursue the ultimate display experience, various display manufacturers are committed to the research and development of high refresh rate products. With the increase of refresh rate, the power consumption of modules increases and becomes more and more obvious; although the current dynamic display frequency is reduced ( The Dynamic Frame Rate (DFR) method can reduce power consumption, because the dynamically reduced display frequency is based on the judgment result of the data of the current frame and the previous frame (that is, if the current frame matches the data of the previous frame, the display frequency is redu...
