US 2016/0253013 A1 · TOUCH THREE-DIMENSIONAL GRATING AND DISPLAY DEVICE

Abstract

A touch three-dimensional grating and a display device are provided. The touch three-dimensional grating comprises an upper substrate (01) and a lower substrate (02) opposed to each other; a plurality of first strip electrodes (03), arranged on a side of the lower substrate (02) facing the upper substrate (01); a plurality of second strip electrodes (04), intersecting with the plurality of first strip electrodes (03) on a side of the upper substrate (01) facing the lower substrate (02), wherein in a touch time period, a part of the plurality of first strip electrodes (03) any adjacent two of which are spaced by one first strip electrode of the other part of the plurality of first strip electrodes (03) serve as touch driving electrodes (031), and a part of the plurality of second strip electrodes (04) any adjacent two of which are spaced by one second strip electrode of the other part of the plurality of second strip electrodes (04) serve as touch sensing electrodes (042), in a three-dimensional display time period, a part of the plurality of first strip electrodes (03) any adjacent two of which are spaced by one first strip electrode of the other part of the plurality of first strip electrodes (03) serve as first three-dimensional driving electrodes (032), and all of the plurality of second strip electrodes (04) serve as another three-dimensional driving electrode; or, a part of the plurality of second strip electrodes (04) any adjacent two of which are spaced by one second strip electrode of the other part of the plurality of second strip electrodes (04) serve as second three-dimensional driving electrodes (032), and all of the plurality of first strip electrodes (03) serve as another three-dimensional driving electrode. The display device with the above structure can realize the touch control function and the bidirectional three-dimensional display function in a time-sequence manner; moreover, an assembly structure and a production process are simplified and a manufacturing cost and an assembly thickness are reduced.
