Touch glasses-free grating 3D display device and manufacturing and control methods thereof
A touch glasses-free grating 3D display device and manufacturing and control methods thereof. The touch glasses-free grating 3D display device includes a display panel and an electrochromic 3D glasses-free grating disposed on the display panel. The electrochromic 3D glasses-free grating includes a plurality of mutually parallel first grating electrodes, a plurality of mutually parallel second grating electrodes and an electrochromic material disposed between the plurality of mutually parallel first grating electrodes and the plurality of mutually parallel second grating electrodes. Both the plurality of first grating electrodes and the plurality of second grating electrodes are transparent conductive electrodes. The display panel is provided with or includes a plurality of touch electrodes which are intercrossed with and insulated from the plurality of first grating electrodes and the plurality of second grating electrodes. The first grating electrodes and the second grating electrodes not only can apply 3D driving voltage signals but also can apply touch driving signals or output touch sensing signals.
