Touch liquid crystal grating, manufacturing method thereof and touch 3D display device
First Claim
1. A touch liquid crystal grating, comprising:
- a first substrate;
a second substrate, cell-assembled with the first substrate;
a liquid crystal layer, filled between the first substrate and the second substrate;
a plurality of first electrodes, disposed on a side of the first substrate facing the liquid crystal layer parallel to and spaced apart from each other;
an insulating layer, covering the plurality of first electrodes;
a plurality of second electrodes, disposed on a side of the insulating layer facing the liquid crystal layer spaced apart from each other and extending parallel to the plurality of first electrodes, each of the plurality of second electrodes directly corresponding to each of the plurality of first electrodes and comprising at least two second sub-electrodes, a spacing region being between adjacent two second electrodes;
wherein the plurality of first electrodes are disposed on a different layer from the plurality of second electrodes separated by the insulating layer such that the first electrodes serve as a shielding layer for shielding electrical signals emitted from the underlying second electrodes;
a plurality of second touch electrodes, parallel to each other and disposed in the same layer with the plurality of second electrodes, each of the second touch electrodes being located in one spacing region;
a plurality of first touch electrodes, disposed parallel to each other on a side of the first substrate opposite to the liquid crystal layer,wherein when the touch liquid crystal grating is powered on, the first touch electrodes and the second touch electrodes function to realize a touch function;
liquid crystal molecules in regions under the plurality of second electrodes rotate, and liquid crystal molecules in regions under the plurality of second touch electrodes do not rotate, forming the liquid crystal grating.
