Abstract

The invention provides a display drive circuit and a display panel. The display drive circuit comprises a drive unit, wherein the drive unit comprises a drive signal output end and an enable signal input end, and the drive signal output end is electrically connected with a data line of the display panel; a detection unit which comprises a detection signal input end and an enable signal output end,wherein the detection signal input end is electrically connected with a grid signal end of a preset row of the display panel, and the enable signal output end is electrically connected with the enable signal input end of the driving unit; wherein the detection unit is used for detecting a grid signal of a preset row and outputting a corresponding enable signal according to a signal detection result, and the driving unit is used for outputting different driving signals according to different enable signals. By increasing the driving signals of the data lines after the preset row, the chargingeffect of the part, far away from the driving ends of the data lines, of the large-size display panel is improved, and then the display difference of the display panel is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving circuit and a display panel. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute exemplary techniques. [0003] With the development of science and technology, the requirements for LCD TVs are getting higher and higher, such as higher resolution requirements and larger size requirements. Due to the increasing size, when the data line is charging the display panel, the charging difference between the near end and the far end becomes more and more obvious. Due to the poor charging effect, the part farther from the end will have lower brightness, resulting in inconsistent display effects of the display panel. Contents of the invention [0004] The main purpose of the present invention is to provide a data driving circuit and a display panel, aiming to solv...
