Abstract

A touch three-dimensional grating and a display device are provided. The touch three-dimensional grating includes an upper substrate, a lower substrate, a plurality of first strip electrodes, and a plurality of second strip electrodes, wherein in a touch time period, a part of the plurality of first strip electrodes serve as touch driving electrodes, and a part of the plurality of second strip electrodes serve as touch sensing electrodes, in a three-dimensional display time period, a part of the plurality of first strip electrodes serve as first three-dimensional driving electrodes, and all of the plurality of second strip electrodes serve as another three-dimensional driving electrode; or, a part of the plurality of second strip electrodes serve as second three-dimensional driving electrodes, and all of the plurality of first strip electrodes serve as another three-dimensional driving electrode.
