Abstract
A display device, a method for producing a display device, and a gesture recognition method are disclosed. The display device includes a display module including a base and an array substrate, a resin layer, a first electrode layer, a pixel definition layer, a light-emitting unit layer, a second electrode layer disposed opposite to the first electrode layer, and an encapsulation layer. The light-emitting unit layer is between the first electrode layer and the second electrode layer and includes a plurality of light-emitting units respectively in a plurality of openings of the pixel definition layer, and an ultrasonic sensor including the second electrode layer, a piezoelectric material layer between the first electrode layer and the pixel definition layer, and a third electrode layer between the pixel definition layer and the resin layer. The piezoelectric material layer includes a plurality of piezoelectric material units separated by the plurality of light-emitting units.
