Abstract

The present application provides an adjustment method and an adjustment device for a display panel. A method for adjusting a display panel includes the following steps: obtaining a minimum refresh rate and a maximum refresh rate of the display panel; calculating a standard parameter value of the display panel based on the minimum refresh rate and the maximum refresh rate; judging the standard Whether the parameter value meets the preset condition; when the standard parameter value does not meet the preset condition, increase the pixel charging time at the lowest refresh rate, and / or decrease the pixel charging time at the highest refresh rate. The present application increases the pixel charging time at the lowest refresh rate and / or reduces the pixel charging time at the highest refresh rate, so that the brightness during the display period at the lowest refresh rate is higher than that at the highest refresh rate, so as to offset the leakage caused by the leakage current. The difference in brightness between the lowest refresh rate and the highest refresh rate during non-display periods. Thereby reducing the standard parameter value and making the standard parameter value as close to the standard as possible.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an adjustment method and an adjustment device for a display panel. Background technique [0002] Frame synchronization (FreeSync) technology is a technology used in the display industry to dynamically adjust the refresh rate of the display to solve problems such as screen freezes and frame errors. FreeSync technology allows the monitor to communicate with the graphics card, allowing the monitor to dynamically change its refresh rate, synchronizing with the current frame generated by the Graphics Processing Unit (GPU), ensuring that no new frames are formed during the refresh period, thus avoiding screen shots torn. At the same time, because the refresh rate is locked at the rate at which new frames are generated, FreeSync technology does not cause the picture to "stutter". [0003] The industry mainly judges whether the display complies with the FreeSync standar...
