Abstract
A touch grating, a display device and a method of realizing stereoscopic display and touch functions. The touch grating includes: a first substrate (101); a second substrate (102), disposed in opposition to the first substrate (101); a planar electrode (103), disposed at an inner side of the first substrate (101) facing the second substrate (102); a plurality of strip-shaped electrodes (104), being parallel to each other and disposed at an inner side of the second substrate (102) facing the first substrate (101); and liquid crystal (108), disposed between the first substrate (101) and the second substrate (102) and driven by the planar electrode (103) and the strip-shaped electrodes (104), wherein wirings (105) are provided at four terminals of the planar electrode (103), respectively, and the wirings (105) provided at the four terminals are used to determine a touch position.
