Abstract

The invention provides a scattering element, a light source system and a display device, the scattering element comprises a substrate, and the surface of the substrate is provided with a reflection scattering layer which is arranged in a first area of the surface of the substrate and is used for performing reflection type scattering on light; a transmission scattering layer arranged in the secondarea on the surface of the substrate and is used for carrying out transmission scattering on light rays; wherein the first area and the second area are not overlapped. According to the scattering element provided by the invention, the reflection scattering layer and the transmission scattering layer scatter light rays, so that the coherence of incident light rays is favorably eliminated, and the speckle phenomenon formed by laser in the incident light rays can be well eliminated.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a scattering element, a light source system and a display device. Background technique [0002] This section is intended to provide a background or context to a detailed description of the invention that is recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, according to the requirements of the human eye for image color reproduction, it can be divided into various color gamut standards, such as Rec709, DCI-P3 and Rec2020 and other color gamut standards. see figure 1 , is a schematic diagram of multiple color gamut ranges in the CIE1931 coordinate system. Such as figure 1 As shown, in the CIE1931 coordinate system, the range covered by various color gamut triangles represents the range of colors that can be displayed, that is, the color gamut. In image color restoration, images of different color ...
