Abstract

A liquid crystal display device and a drive method thereof. The liquid crystal display device comprises a scanning drive module (710), a data drive module, a pixel (720), a data line (730), a shift register module (740) and a scanning line (750). The scanning line (750) comprises a first type of scanning line (GATE_N) and a second type of scanning line (SHARING_N). The first type of scanning line (GATE_N) is connected to the scanning drive module (710) and the pixel (720), and is used for controlling charging time of the pixel (720) according to a first scanning signal; the second type of scanning line (SHARING_N) is connected to the shift register module (740) and the pixel (720), and is used for controlling drive time of sub-pixels of the pixel (720) according to a second scanning signal. Reverse scanning is implemented without increasing the device cost, thereby solving the technical problem that a due drive effect cannot be ensured when an existing liquid crystal display device uses reverse scanning drive.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device capable of realizing reverse scanning without increasing cost and a driving method thereof. Background technique [0002] Current liquid crystal display devices generally use figure 1 The connection between the scan line and the pixel shown in the drive, figure 2 for figure 1 The driving signal waveform diagram of the scan line is shown. Such as figure 1 As shown, each pixel is connected to a scan line (such as GATE_N, GATE_N+1, GATE_N+2), and the driving waveform of the scan line is as follows figure 2 As shown, the scan lines are turned on sequentially, and the waveform width of each scan line is about 10-20 μs. [0003] When the liquid crystal display device has a multi-domain design, the connection mode between the scan line and the pixel is as follows: image 3 As shown, each pixel in the figure is connected to two scan lines, one...
