LIQUID CRYSTAL GRATING AND MANUFACTURING METHOD AND DRIVE METHOD THEREFOR, AND SPLICING SCREEN

摘要

A liquid crystal grating and a manufacturing method and drive method therefor, and a splicing screen comprising the liquid crystal grating. The liquid crystal grating comprises: a first substrate (11) and a second substrate (12) which are oppositely arranged; and liquid crystal molecules (15) filled between the first substrate (11) and the second substrate (12), wherein the first substrate (11), the second substrate (12) and the liquid crystal molecules (15) define at least one grating unit (2). Each grating unit (2) comprises: a display region (22); a frame region (21) surrounding the display region (22); a first frame electrode (131) located on the first substrate (11) and arranged corresponding to the frame region (21); and a second frame electrode (141) located on the second substrate (12) and arranged corresponding to the frame region (21). The first frame electrode (131) and the second frame electrode (141) are used for forming a voltage difference when displaying in the display region (22), so as to control the steering of the liquid crystal molecules (15) in the frame region (21), to enable light rays scattered in the frame region (21) to be emitted out from the frame region (21) of the second substrate (12). The liquid crystal grating enables a joint of a splicing screen to have a certain display brightness, thereby improving the display effect of the splicing screen.
