Display panel and display apparatus

Abstract

A display panel includes a base substrate having a first surface and a second surface arranged opposite each other. The display panel further includes a plurality of light-emitting units on the first surface of the base substrate, and a plurality of sound-generating units on the first surface of the base substrate and between adjacent light-emitting units. The sound-generating unit includes: a piezoelectric device on the first surface of the base substrate; a sound focusing structure arranged on the first surface of the base substrate and surrounding the piezoelectric device; and a back cavity arranged on the second surface of the base substrate and recessed towards the first surface. The back cavity is arranged corresponding to the piezoelectric device.
