Abstract
The invention discloses a laser speckle suppression device, a laser speckle suppression device and display equipment. The laser speckle suppression device comprises a piezoelectric ceramic element and a reflector plate, wherein the reflector plate is fixed on the first surface of the piezoelectric ceramic element; the piezoelectric ceramic element comprises at least one piezoelectric ceramic body and an electrode. The reflector plate is driven by the piezoelectric ceramic element to vibrate, so that coherence of laser is reduced, speckle suppression is achieved, a motor is not needed, high stability and reliability are achieved, the overall size of an optical machine is reduced, the service life of the optical machine is prolonged, working noise of the optical machine is reduced, and the service life of the optical machine is prolonged. And the use comfort of the user is improved.
