Claim Text:
1. A liquid crystal grating, comprising: a first substrate; a second substrate, disposed opposite to the first substrate; a liquid crystal layer, filled between the first substrate and the second substrate; a touch electrode layer, located on a side of the first substrate that faces the liquid crystal layer; and a planar electrode, located on a side of the second substrate that faces the liquid crystal layer, wherein the touch electrode layer includes a plurality of strip-shaped electrodes parallel to each other and arranged separately at a set distance, and the strip-shaped electrodes in the touch electrode layer are divided, based on a determined pattern segmentation rule, into at least two touch electrode units that are not electrically connected to each other, for any one of the touch electrode units, when an external conductive object touches different positions of the touch electrode unit by way of single-point touch, variation of capacitance formed between the touch electrode unit and the external conductive object differs from one another.
