TOUCH GRATING CELL AND TOUCH STEREOSCOPIC DISPLAY DEVICE

摘要

A touch grating cell and a touch stereoscopic display device are provided. The touch grating cell comprises: a first substrate (10) and a second substrate (20) arranged opposite to each other; a liquid crystal layer (30) arranged between the first substrate (10) and the second substrate (20); a first transparent electrode structure (40), arranged on the first substrate (10); and a second transparent electrode structure (50), arranged on the second substrate (20), wherein each of the first transparent electrode structure (40) and the second transparent electrode structure (50) includes a plurality of multiplex electrodes (41, 51); in a touch period, the multiplex electrode (41) in the first transparent electrode structure (40) and the multiplex electrode (51) in the second transparent electrode structure (50) 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 (41) in the first transparent electrode structure (40) and the multiplex electrode (51) in the second transparent electrode structure (50) 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.
