Abstract
Provided is a liquid crystal handwriting board. The liquid crystal handwriting board includes: a liquid crystal panel, and a drive assembly electrically connected to the liquid crystal panel; wherein the liquid crystal panel includes: a first substrate and a second substrate that are opposite to each other, and a liquid crystal layer disposed between the first substrate and the second substrate; and the drive assembly is configured to apply, based on position information of a region to be erased, a pixel voltage to a pixel electrode in the region to be erased in the case that the liquid crystal handwriting board is in an erasing mode, such that a voltage difference is developed between the pixel electrode in the region to be erased and the common electrode.
