Problems solved by technology
[0004] However, in actual situations, the signal waveform of the scan line will be affected by the line load (RC Delay) as follows: Figure 1a The distortion shown is such that there is a period in which the charging scan line and the shared scan line are turned on at the same time in the timing
The effect of charging sharing is abnormal, and there may be color shift and uneven display
[0005] Therefore, there is an urgent need to provide a new type of liquid crystal display panel to avoid the abnormal charge sharing effect caused by the scan line load

The invention discloses a liquid crystal display panel, a driving method thereof, and a liquid crystal display device. The liquid crystal display panel includes a plurality of sub-pixels, and each sub-pixel includes first and second display areas, and the first and second display areas receive a scan signal of a charging line, and further receive a data signal of a data line to Having a first potential, the second display area receives a scan signal of a shared line after a delay period, so as to pull down the first potential of the second display area to a second potential; wherein, the delay The time period is at least three scanning cycles, so as to avoid that the scanning signals of the charging line and the sharing line are valid at the same time.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel, a driving method thereof, and a liquid crystal display device. Background technique [0002] In order to improve the color shift phenomenon of the vertically aligned liquid crystal display at large viewing angles, a charge sharing (Charge Sharing) sub-pixel design is usually adopted. The sub-pixel is divided into two regions, the main pixel (Main Pixel) and the sub-pixel (SubPixel), and the voltage of the sub-pixel region is pulled down by sharing the thin film transistor (TFT) and the pull-down capacitor, so that the potential of the sub-pixel region is lower than that of the main pixel region potential. Different potentials make the distribution of liquid crystal molecules in the two display areas different, thus having the effect of improving the angle deviation of large viewing angles. [0003] In order to realize the above-mentioned chargin...
