Title:
LIGHT SOURCE DEVICE, PROJECTION APPARATUS AND 3D APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/000797
Kind Code:
A1
Abstract:
A light source device, comprising a laser generation unit (21), a light modification member (22), a light guide unit (23) and a dodging unit (24). The light modification member (22) may enable the laser beam angle to be uniformly distributed. The 3D apparatus comprises a polarized beam splitting device (26), a light engine device (25) and a light source device, such a design may weaken the spatial coherence of the laser so as to make the laser beam angle to be distributed uniformly and continuously, thereby weakening the diffraction phenomena caused by the laser irradiating at a seam of the polarized beam splitting prism in a 3D device and greatly improving the viewing effect.
