Abstract

The invention discloses a time sequence controller. The time sequence controller comprises a detection unit, a control unit and a compensation unit, the compensation code value is called through the change amount of the refresh frequency, and the second basic code value in the white balance data driving table is correspondingly compensated based on the first basic code value, so that the problem of picture flicker caused by overlarge corresponding gray-scale voltage difference before and after refresh frequency switching can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to the technical field of timing controllers, and in particular to a timing controller, a gray scale voltage adjustment method and a liquid crystal display panel. Background technique [0002] FreeSync (picture adaptive synchronization technology) monitors allow graphics cards and accelerator processors to directly and dynamically control the refresh rate of the monitors connected to them. For monitors that support FreeSync, the refresh rate of the monitor can be adjusted down or up, and it will automatically keep consistent with the frame rate of the game, which can avoid the phenomenon of screen tearing. [0003] However, when the refresh rate of the above-mentioned display is automatically switched, due to the delay in the detection response and liquid crystal response, the code value in the wrong white balance data drive table is called at the moment of ...
