1. A display apparatus, comprising:
a display screen;
a touch screen located at a light-emitting side of the display screen, wherein the touch screen comprises a tactile sensor configured to generate a standing wave on a surface of the touch screen when working; and
a fixing structure located between the display screen and the touch screen, wherein a Young's modulus of the fixing structure is less than 0.1 MPa, and the fixing structure is configured to maintain a gap between the touch screen and the display screen that is not less than an amplitude of the standing wave when the tactile sensor is turned off,
wherein the touch screen comprises a substrate, and a touch structure, a first insulation layer, the tactile sensor, and a planarization layer that are stacked in sequence on a side of the substrate facing the display screen.
