LASER DISPLAY DEVICE AND METHOD THEREOF

摘要

The present invention relates to a laser display device and a method thereof, which can reduce a speckle pattern and a flickering phenomenon together by generating mutually different circularly polarized lights (for example, a right circularly polarized light and a left circularly polarized light) having mutually different phases. To this end, a laser display device according to one embodiment of the present invention composes a plurality of linearly polarized lights having mutually different color light incidents from laser light sources, sequentially generates mutually different circularly polarized lights having mutually different phases on the basis of the composed linearly polarized light, and can display an image on the basis of the mutually different circularly polarized lights.
