Abstract

The embodiment of the invention provides a gamma adjusting method and device for a display panel, a driving chip and a display device, which are used for performing gamma adjustment on the display panel and improving the brightness uniformity of different areas in the display process of the display panel. The display panel comprises a first display area and a second display area; the display brightness of the display panel has a plurality of brightness levels. The method for performing gamma adjustment under any brightness level comprises the following steps: acquiring a plurality of binding point gray scales corresponding to a second display area; enabling the first display area and the second display area to be displayed in the same binding point gray scale in sequence; under each binding point gray scale, taking the brightness of the second display area under the current binding point gray scale as a reference to obtain regulation and control parameters, corresponding to the binding point gray scales, of the first display area; wherein the absolute value of the difference value between the brightness of the first display area under the regulation and control parameters and the brightness of the second display area under the current binding point gray scale is smaller than or equal to a preset value.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a gamma adjustment method for a display panel, a gamma adjustment device, a driving chip, and a display device. 【Background technique】 [0002] Gamma adjustment is a process in the production process of display modules. At present, before the panel structure of the display module is manufactured and leaves the factory, the display module needs to be adjusted for gamma, the purpose of which is to adapt the display effect of the display module to the non-linear perception characteristics of brightness of the human eye. In related technologies, the overall gamma adjustment is usually performed on the entire display panel. After the relevant gamma parameters obtained after gamma adjustment are written into the driver chip, the display is driven according to the same set of gamma parameters in the subsequent display process. Multiple regions at different positions in the panel are...
