Abstract

A light source system and projection system, the light source system comprising: a first light source (1) producing first wide spectrum light, a second light source (103) producing second wavelength light, a light splitting and light combining device (2) used to split and combine light, a first spatial light modulator (106), a second spatial light modulator (107), and a controller (108) controlling the first light source (1) and the second light source (103) and modulating the first spatial light modulator (106) and the second spatial light modulator (107). The projection system comprises the light source system. The light source system and projection system have high brightness and wide color gamut, effectively eliminating rainbow effect, and also have a simple structure and low cost.

Description

technical field [0001] The invention relates to the field of optical display, more specifically, to a light source system and a projection system. Background technique [0002] With the maturity of projection display technology, the market has gradually developed from the original single-chip DMD projection technology to three-chip DMD projection display system. [0003] In the traditional single-chip DMD projection technology, the light source adopts white light source. After the white light source passes through the spectral filter, the three primary colors of red, green, and blue are sequentially generated, and the three primary colors of red, green, and blue reach the DMD in sequence. Exit after DMD treatment. Although this single-chip DMD projection system has a simple structure, the utilization rate of the light source is very low, and most of the light is lost after passing through the spectral filter, which leads to low brightness of the projection system. Moreover...
