Display driving circuit, display device and display driving method

Abstract

The invention provides a display driving circuit, a display device and a display driving method. The display driving circuit comprises a timing control unit, a modulation unit and a beveling unit, wherein the timing control unit is connected with the modulation unit, and used for generating row selection signals, first control signals and second control signals based on a preset clock signal; the first control signals comprises a beveling width signal and a beveling depth signal; the second control signals comprise a width modulation signal and / or a depth modulation signal; the modulation unit is connected with the beveling unit, and used for modulating the row selection signals into the first control signals within an active level time period according to the second control signals; the beveling unit is used for beveling grid voltage signals according to the first control signals modulated by the modulation unit before outputting the grid voltage signals. Therefore, through adoption of the display driving circuit, the display device and the display driving method, the problem of a significant difference in charging effect among pixels connected to different rows of grid scanning lines in the prior art can be solved, and improvement of the display effect is facilitated.

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 a problem that the charging effect is significantly different between pixels connected by different row gate scanning lines. . For example 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 d...
