Problems solved by technology

[0004] However, the source driver is generally arranged at the lower border of the display panel, so that equal resistance cannot be set between each data line and the source driver, that is, the wiring between the data line near the source driver and the source driver Shorter, lower resistance, longer traces and higher resistance between the data line and the source driver at the position away from the side edge, resulting in uneven charging of the area away from the source driver and the area close to the source driver on the panel The problem

Embodiment Construction

[0037] 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.

[0038] 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 configured 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.

[0039] In addition, if there are descriptions involving "first", "second...

Abstract

The invention discloses a display module, a gamma voltage regulation method thereof and a display device. The display module comprises a display panel, a time sequence controller, a gamma circuit anda source driver, wherein the display panel is internally provided with a pixel array; the time sequence controller is configured to count enabling signals completing the charge for each row of sub-pixels in the pixel array when the display module is in operation and output a corresponding control signal according to the counting times; the gamma circuit is configured to generate multiple sets of gamma reference voltage according to the corresponding control signal, wherein the multiple sets of gamma reference voltage sequentially increase in voltage value; and the source driver is configured to drive the corresponding row of sub-pixels to operate according to the corresponding gamma reference voltage. The display module improves the brightness uniformity of an area away from the source driver and an area close to the source driver of the display panel.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a display module, a gamma voltage adjustment method thereof, and a display device. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. [0003] In order to comply with the development of large-scale and high-resolution LCD TVs, more and more liquid crystal display panels adopt a narrow bezel design. [0004] However, the source driver is generally arranged at the lower border of the display panel, so that equal resistance cannot be set between each data line and the source driver, that is, the wiring between the data line near the source driver and the source driver Shorter, lower resistance, longer traces and higher resistance between the data line and the source driver at the position away from the side edge, resulting in uneven charging of the area...
