Touch grating cell and touch stereoscopic display device

Abstract

A touch grating cell and a touch stereoscopic display device are provided. The touch grating cell comprises: a first substrate () and a second substrate () arranged opposite to each other; a liquid crystal layer () arranged between the first substrate () and the second substrate (); a first transparent electrode structure (), arranged on the first substrate (); and a second transparent electrode structure (), arranged on the second substrate (), wherein each of the first transparent electrode structure () and the second transparent electrode structure () includes a plurality of multiplex electrodes (); in a touch period, the multiplex electrode () in the first transparent electrode structure () and the multiplex electrode () in the second transparent electrode structure () are used as a touch driving electrode and a touch sensing electrode, respectively, and are perpendicular to each other in extending directions; and in a display period, the multiplex electrode () in the first transparent electrode structure () and the multiplex electrode () in the second transparent electrode structure () are used as a common electrode and a grating electrode, respectively. Because a touch function is integrated in the grating cell, the grating electrode and the common electrode are shared with the touch driving electrode and the touch sensing electrode, respectively, so that a production process is reduced, cost is saved, and a purpose of thinning is achieved.
