Abstract
A touch naked-eye 3D grating and a display device are disclosed. The naked-eye 3D grating includes a touch electrode structure between the upper substrate and the plate electrode, and the touch electrode structure includes a plurality of first touch sense lines and a plurality of second touch sense lines arranged to intersect with and insulated from each other, and includes touch electrodes located within the areas defined by adjacent two first touch sense lines and adjacent two second touch sense lines; each touch electrode creates a capacitor with the plate electrode so as to achieve the touch function by way of detecting the signal changes over the first touch sense line and the second touch sense line connected with the touch electrode. The display device includes the aforesaid touch naked-eye 3D grating. This touch naked-eye 3D grating simplifies the assembly configuration as well as its production process, thus reducing overall cost for manufacturing the assembly.
