Abstract

Disclosed is a device for reducing deterioration of image quality which can get rid of speckle by equalizing a laser from a light source on a screen by vibrating a reflective mirror installed between the light source and the screen at a predetermined amplitude. The device for reducing deterioration of image quality in a display system using a laser as a light source includes: a reflective mirror formed at the path of light positioned between the light source and a screen, for reflecting the laser; and a driving unit connected to the reflective mirror and vibrating the reflective mirror at a predetermined amplitude by using an electromagnetic force.
