Title:
SCATTERING ELEMENT, LIGHT SOURCE SYSTEM AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/103784
Kind Code:
A1
Abstract:
A scattering element (250), a light source system (20) and a display device, the scattering element (250) comprising a substrate (251), a surface of the substrate (251) being provided with: a reflection scattering layer, disposed in a first area (252) of the surface of the substrate (251), used to perform reflection scattering of light rays; and a transmission scattering layer, disposed in a second area (253) of the surface of the substrate (251), used to perform transmission scattering of light rays; the first area (252) and the second area (253) not overlapping. The reflection scattering layer and the transmission scattering layer of the scattering element (250) perform scattering of light rays, helping to eliminate coherence of incident light rays, and can thoroughly eliminate speckles formed by a laser in incident light rays.
