Abstract

The invention provides an LCD and the driving method thereof. The LCD comprises a liquid crystal display panel including a plurality of pixels arranged in a matrix form, a plurality of grid lines extended in the row direction and a plurality of data lines intersecting with the grid lines, first and second grid drivers which are located on the two sides of the liquid crystal display panel respectively and apply grid signals onto the grid lines, and a data driver which applies data voltage to the data lines, wherein the grid lines comprise a first grid line and a second grid line, a first pixel among the pixels is connected with the first grid driver through the first grid line, a second pixel among the pixels is connected with the second grid driver through the second grid line, and the data driver is configured to apply data voltage with opposite polarities to the first pixel and the second pixel connected to a same data line in one frame period.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and more specifically relates to a liquid crystal display and a driving method thereof. Background technique [0002] Liquid crystal displays are popular for their small size, light weight, low power consumption, and high display quality. The driving principle of the liquid crystal display is to control the rotation angle of the liquid crystal molecules by changing the voltage applied to the electrodes at both ends of the liquid crystal layer, thereby controlling the amount of light transmitted through the liquid crystal panel. [0003] Generally, if the liquid crystal molecules have been working at a fixed voltage, the characteristics of the liquid crystal molecules will be polarized. After canceling the fixed voltage, the liquid crystal molecules can no longer respond to the change of the applied voltage and deflect accordingly, so the signal voltage driving the liquid crystal ...
