Driving device and driving method of liquid crystal display module and liquid crystal display device

Abstract

The embodiment of the invention discloses a driving device and a driving method of a liquid crystal display module and a liquid crystal display device. In one specific embodiment, the driving method comprises the following steps: receiving a to-be-displayed picture frame signal, and judging whether at least part of a picture region, containing a picture region displayed by a first row of pixels, of a to-be-displayed picture is a row bright and dark alternated picture or not according to the picture frame signal; if yes, applying a gate driving signal based on a first conduction voltage to the TFT gate of the first row of pixels so as to pre-charge the first row of pixels according to the pixel voltage of the first row of pixels corresponding to the picture frame signal; if not, applying a gate driving signal based on a second conduction voltage to the TFT gate of the first row of pixels so as to pre-charge the first row of pixels according to the pixel voltage of the first row of pixels corresponding to the picture frame signal, wherein the first break-over voltage is smaller than the second break-over voltage. According to the embodiment, when the display module displays different pictures, the problem that display of the first row of pixels becomes dark or bright can be avoided.

Description

Technical field [0001] The present invention relates to the display of the technical field. More specifically, it relates to a driving device, a driving method, and a liquid crystal display device of a liquid crystal display module. Background technique [0002] At present, the liquid crystal display device typically implements the screen display in a driving method of progressive scanning. The display panel in the liquid crystal display device includes a plurality of pixels defined by a multi-line data line and a multi-line scan line. The first line of pixel drive is: the first line of scanning line is opened, the data cable is charged for charging the pixel of the first line, and the scan line of the second line is turned on, while the scan line of the first line is turned off, the data line is made to the pixels of the second line. Charging and pushing in this class. [0003] Since the size of the liquid crystal display device is, the higher the resolution, the refresh frequen...

Problems solved by technology

However, the pre-charging mode will cause the charging rate of the first row of pixels and the rest of the row of pixels to be uneven, which will lead to poor display of the first row of pixels
