Problems solved by technology

[0003] In order to solve the problem of crosstalk (Crosstalk) in the panel, a solution in the prior art is to set the polarity automatic selection function in the timing controller (TCON), however, this equal sharing method does not refer to the above polarity The polarity determined during the automatic selection of the polarity, so that when the polarity is changed, the same pattern will still be used, resulting in a very likely side effect or flicker of the pattern after switching the polarity

Abstract

The invention relates to a time schedule controller for a liquid crystal display panel. A datum processing module is provided with an automatic polarity selection unit and a dithering unit, wherein the automatic polarity selection unit is used for receiving an input datum and selecting and outputting a polarity result according to the input datum; the dithering unit is coupled to the automatic polarity selection unit and used for receiving the input datum and the polarity result, and determining an output datum corresponding to the input datum. An inversion control module is provided with a line driving control unit and a column driving control unit, wherein the line driving control unit is used for receiving the polarity result and outputting a line driving signal corresponding to the polarity result; the column driving control unit is used for outputting a column driving signal corresponding to each subpixel. Compared with the prior art, the time schedule controller disclosed by the invention has the advantages that the dithering unit can receive the input datum and the polarity result output by the automatic polarity selection unit, thus determining the output datum corresponding to the polarity result; according to the time sequence controller, dithering pictures can be changed according to different polarity results, and further the boundary effect or sparkling problem can be solved.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a timing controller for a liquid crystal display panel. Background technique [0002] Currently, in the field of thin film transistor liquid crystal displays (TFT-LCD), the color extension (Color Extension) method is often used in conjunction with the gamma curve (Gamma curve), mainly using the principle of energy equalization to make the original brightness of a specific gray scale Increased to obtain additional gray levels for color description. Specifically, the method of dithering mainly includes temporal dithering and spatial dithering. Among them, the equalization in time is changed by the patterns of 4 different frames (Frame), and the equalization in space will have patterns of different dithering levels, and this information is determined by Gamma Curve . [0003] In order to solve the problem of crosstalk (Crosstalk) in the panel, a solution in the prior art is to...
