Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, if there are descriptions involving "first", "second" and ...

Abstract

A Gamma voltage regulation circuit and a display apparatus. The Gamma voltage regulation circuit comprises: a Gamma voltage input end (Gma-in) and a Gamma voltage output end (Gma-out); a switching control circuit (10) configured to generate a first control signal or a second control signal according to a received timing control signal; a Gamma voltage output circuit (20) configured to be turned on when a first switching signal is received and to output a first Gamma voltage input from the Gamma voltage input end (Gma-in) to the Gamma voltage output end (Gma-out); and a Gamma voltage processing circuit (30) configured to convert, when the second control signal is received, the first Gamma voltage input from the Gamma voltage input end (Gma-in) into a second Gamma voltage and then output same to the Gamma voltage output end (Gma-out).

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: ...
