Abstract

The invention discloses a liquid crystal handwriting board, a handwriting device and a method for controlling the handwriting device, and belongs to the technical field of display. The liquid crystalhandwriting board comprises a liquid crystal panel and a driving assembly. The liquid crystal panel comprises a first substrate, a second substrate, a liquid crystal layer, and a liquid crystal layerlocated between the first substrate and the second substrate, wherein the first substrate and the second substrate are oppositely arranged, . The pixel electrodes in the first substrate in the liquidcrystal panel are the plurality of blocky electrodes, so that when the liquid crystal handwriting board is in the erasing mode, the driving assembly electrically connected with the liquid crystal panel can apply pixel voltage to the blocky pixel electrodes in the to-be-erased area based on the position information of the to-be-erased area; so that a voltage difference is formed between the pixel electrode in the to-be-erased area and the common electrode, liquid crystal molecules in the to-be-erased area in the liquid crystal layer are rearranged under the action of the voltage difference, thelocal area of the liquid crystal handwriting board can be erased, and the use flexibility of the liquid crystal handwriting board is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal tablet, a handwriting device and a control method for the handwriting device. Background technique [0002] A tablet is an electronic device used for writing and drawing. Among them, the liquid crystal tablet has the advantages of low power consumption and clear handwriting, and has occupied a large market share in China in recent years. However, the current liquid crystal tablet can only realize the erasing of the whole surface, and the flexibility of use is low. Contents of the invention [0003] Embodiments of the present application provide a liquid crystal tablet, a handwriting device, and a control method for the handwriting device. It can solve the problem of low flexibility of use of the liquid crystal tablet in the prior art, and the technical scheme is as follows: [0004] On the one hand, a liquid crystal tablet is provided, and the liq...
