Beschreibung
Zusammenfassung:	A liquid crystal handwriting board, comprising: a liquid crystal panel (001) and a driving assembly (002). The liquid crystal panel (001) comprises: a first substrate (100) and a second substrate (200) which are arranged opposite to each other, and a liquid crystal layer (300) located between the first substrate (100) and the second substrate (200). As pixel electrodes (101) in the first substrate (100) of the liquid crystal panel (001) are a plurality of block electrodes, when the liquid crystal handwriting board is in an erasing mode, the driving assembly (002) electrically connected to the liquid crystal panel (001) can apply, on the basis of position information of an area to be erased, a pixel voltage to a block pixel electrode (101) in said area, so that a voltage difference is formed between the pixel electrode (101) in said area and a common electrode (201), and thus liquid crystal molecules located in said area in the liquid crystal layer (300) is rearranged under the action of the voltage difference, achieving erasion of a local area of the liquid crystal handwriting board. Also provided are a handwriting apparatus, and a method for controlling the handwriting apparatus.
