TOUCH LIQUID CRYSTAL GRATING, 3D TOUCH DISPLAY DEVICE AND DRIVING METHOD OF TOUCH LIQUID CRYSTAL GRATING
First Claim
1. A touch liquid crystal grating, comprising:
- a first substrate;
a second substrate, cell-assembled with the first substrate; and
a liquid crystal layer, filled between the first substrate and the second substrate;
a plurality of grating electrodes, which are located on a side of the first substrate that faces the liquid crystal layer and extend along a first direction, each of the plurality of grating electrodes being located within each of strip-like regions with spacing regions being provided therebetween;
a plurality of touch driving electrodes, which extend along the first direction and are located on the side of the first substrate facing the liquid crystal layer, the touch driving electrodes being located within the spacing regions between adjacent strip-like regions; and
a plurality of touch sensing electrodes, which extend along a second direction and are located on a side of the first substrate opposed to the liquid crystal layer,wherein the first direction is different from the second direction, and in a condition that the plurality of grating electrodes are electrified, liquid crystal molecules corresponding to each of the strip-like regions are deflected, and liquid crystal molecules corresponding to each of the spacing regions are not deflected.
