Description
technical field [0001] The present invention relates to the field of liquid crystal display, in particular to an array substrate, a display device and a method for driving the array substrate. Background technique [0002] The liquid crystal display device is a device widely used in various electronic devices. Its display principle is to apply a voltage difference to the liquid crystal molecules. The voltage difference generates an electric field to drive the liquid crystal molecules to deflect. The degree of deflection of the liquid crystal molecules is controlled by the magnitude of the applied voltage difference. , so as to control the brightness and darkness of the light emitted through the liquid crystal layer to display images, and the voltage difference (driving voltage difference) applied to the liquid crystal molecules must be reversed at regular intervals to avoid polarization of the liquid crystal material. Cause permanent damage, and also to avoid image residual ...
