A1
Abstract:
A liquid crystal handwriting board (000), comprising: a first substrate (100), a second substrate (200) and a liquid crystal layer (300), wherein a transistor (102) in the first substrate (100) is electrically connected to a pixel electrode (103). The area of a channel region (102a) of the transistor (102) is relatively large, and therefore the transistor (102) is relatively sensitive to light, and can be turned on more easily after being irradiated by target light.
