Display driving circuit, display device and display driving method

Abstract

The present invention provides a display driving circuit, a display device and a display driving method, wherein the display driving circuit includes: a timing control unit, a modulating unit, and a chamfering unit, wherein: the timing controlling unit is connected to the modulating unit, and is used to The signal generates a line selection signal, a first control signal including a chamfer width signal and a chamfer depth signal, and a second control signal including a width modulation signal and / or a depth modulation signal; the modulating unit is connected to the chamfer unit, for according to the first The second control signal modulates the first control signal in the period when the line selection signal is at an effective level; the chamfering unit is used to perform the grid voltage signal according to the first control signal modulated by the modulation unit before outputting the grid voltage signal Chamfered treatment. Based on this, the present invention can solve the problem in the prior art that there is a significant difference in charging effect between pixels connected by different row gate scanning lines, which is beneficial to the improvement of display effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving circuit, a display device and a display driving method. Background technique [0002] In the existing liquid crystal display (Liquid Crystal Display, LCD), due to the difference in the arrangement of the pixel electrode array and the type of polarity inversion, there may be significant differences in the charging effect between pixels connected by different row gate scan lines The problem. E.g figure 1 In the prior art shown in a Z inversion charging mode under a double-gate structure, the charging polarities of the data lines in the first column between the pixels in the first two rows are "+", "+", "-", "-". Among them, such as figure 1 As shown by the oblique arrow in , when the charging polarity of the data line in the first column is changed from "+" to "-", the voltage amplitude span is too large and the parasitic capacitance on the data line will mak...
