3D touch display device, its manufacturing method and driving method

摘要

The present disclosure provides a three-dimensional (3D) touch display device, its manufacturing method and driving method. Touch sensing electrodes and liquid crystal driving electrodes are arranged alternately at an identical layer and insulated from each other in a 3D grating cell. The touch sensing electrodes and the liquid crystal driving electrodes are arranged between an insulating layer and a second substrate, and the liquid crystal driving electrode is configured to drive liquid crystals between the liquid crystal driving electrode and a first substrate to deflect horizontally at a display stage. An electrode layer arranged on a third or fourth substrate is configured to receive a touch driving signal at a touch stage so as to detect a touch operation, and receive a first common electrode signal at the display stage so as to display an image.
