Abstract

The invention discloses a gamma voltage adjusting circuit and a display device; the gamma voltage adjusting circuit comprises the following parts: a gamma voltage input end and a gamma voltage outputend; a switch control circuit configured to form a first control signal or a second control signal according to a received sequential control signal; a gamma voltage output circuit configured to conduct when receiving a first switch signal, and to output a first gamma voltage inputted by the gamma voltage input end to the gamma voltage output end; a gamma voltage processing circuit configured to convert the first gamma voltage inputted by the gamma voltage input end into a second gamma voltage when receiving a second control signal, and to output the second gamma voltage to the gamma voltage output end. The gamma voltage adjusting circuit can improve the image quality of a display panel.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a gamma voltage regulating circuit and a display device. Background technique [0002] With the development of display technology, display devices are increasingly developing toward low cost and high image quality. For example, gate drivers can be added and the number of source drive circuits can be reduced to reduce costs. However, this makes the charging rate of the display panel unable to be consistent, which makes the display panel pixels prone to color shift and other picture quality problems. Contents of the invention [0003] The main purpose of the present invention is to provide a gamma voltage adjustment circuit and a display device, aiming at improving the picture quality of the display panel. [0004] In order to achieve the above object, the present invention proposes a gamma voltage regulation circuit, the gamma voltage regulation circuit includes: ...
