Array substrate, drive method thereof, liquid crystal display panel and display device

Abstract

The invention discloses an array substrate, a drive method thereof, a liquid crystal display panel and a display device. The array substrate comprises a substrate, pixel electrodes, compensation capacitors, control lines and a control circuit. The pixel electrodes are in a floating state after being charged, and the control circuit applies voltage with polarity identical to that of voltage on the pixel electrodes to the compensation capacitors. According to the capacitance and charge conservation principle, the voltage difference at two ends of each compensation capacitor is to keep the state when the pixel electrodes are charged, so that the voltage at the other end of the compensation capacitor changes identically when the control circuit applies voltage to one end of the compensation capacitor, and the voltage amplitude of the pixel electrodes is increased. When the array substrate is applied to the liquid crystal display panel, the voltage amplitude of the pixel electrodes is increased, the electric field controlling liquid crystal molecules to turn over is enhanced, and accordingly, response time of the liquid crystal molecules is shortened. The array substrate provided by the embodiment solves the problem of reduced liquid crystal response speed at a low temperature in the prior art, and the liquid crystal display quality is improved.

Description

technical field [0001] The present invention relates to a display device, in particular to an array substrate, a driving method thereof, a liquid crystal display panel and a display device. Background technique [0002] A liquid crystal display generally includes an upper substrate and a lower substrate of a cell, and a layer of liquid crystal molecules filled between the upper substrate and the lower substrate. When displaying a picture, due to the formation of an electric field between the driving voltage loaded on the pixel electrode of each pixel and the common electrode voltage on the common electrode, the liquid crystal molecules will deflect under the action of the electric field, and the degree of deflection is different, resulting in different transmittance. , so as to realize the screen display. [0003] However, due to the viscous effect of the liquid crystal molecules, there will be a time course for the liquid crystal molecules to deflect to the expected state,...
