Embodiment Construction
[0039] The inventors found that in the existing thin-film transistor liquid crystal display device adopting a double scanning line structure, each scanning line is turned on sequentially according to the natural order, and then the data line is turned on correspondingly to charge each sub-pixel. The above-mentioned driving method will cause differences in the charging time of the sub-pixels of adjacent columns sharing the same data line due to the delay effect of the signal, and will produce linear unevenness of light and dark stripes between columns on the final displayed image, Affects the display of images.
[0040] The present invention provides a method for driving a liquid crystal display device. The liquid crystal display device is a thin film transistor liquid crystal display device adopting a double scanning line structure, and each thin film transistor is coupled to a scanning line and a data line. The driving method includes: When any frame of image is displayed, th...

The invention provides a liquid crystal display device, as well as a drive method and a drive circuit thereof. The liquid crystal display device is a thin film transistor liquid crystal display device of a double scan line structure, and each thin film transistor is coupled to scan lines and a data line; the drive method comprises the following steps of sequentially switching on each scan line ina first scan sequence when an L frame image is displayed; sequentially switching on each scan line in a second scan sequence which is different from the first scan sequence when an L+1 frame image isdisplayed, wherein two sub pixel points which share the data line adopt a first data writing sequence in the first scan sequence and adopt a second data writing sequence in the second scan sequence, and the first data writing sequence is reverse to the second data writing sequence, therefore, the charging time of each pixel point in two adjacent frame images is neutralized, and the phenomenon of uneven linearity is reduced and even eliminated.
Description
technical field [0001] The invention relates to liquid crystal display technology, in particular to a liquid crystal display device, a driving method and a driving circuit thereof. Background technique [0002] Due to the advantages of lightness, thinness, small footprint, low power consumption, and low radiation, liquid crystal display devices are widely used in various data processing equipment, such as televisions, notebook computers, mobile phones, and personal digital assistants. With the continuous development of the electronic industry, the performance of liquid crystal display devices is getting higher and higher. [0003] Taking a common thin film transistor LCD (Thin Film Transistor LCD, TFT-LCD) as an example, it is a kind of active matrix liquid crystal display. The main feature of TFT-LCD is that each pixel is equipped with a semiconductor switching device, and each pixel is an independent transistor isolated from each other. Since each pixel can be directly co...
