Abstract

See full text

A light source system and a projection display device comprising the light source system. The light source system comprises at least three light sources (10, 20, 30) used for generating at least two wide-spectrum light beams, a light splitting and combining device (40), and at least two spatial light modulators, i.e. a first spatial light modulator (50) and a second spatial light modulator (60), wherein a first wide-spectrum light beam and a second wide-spectrum light beam generate light with two colors and at least four primary wavelengths after being split by the light splitting and combining device (40), thereby expanding the color gamut range and improving the quality of image display. In addition, using two spatial light modulators to modulate light simultaneously takes account of the costs of products while guaranteeing the image display quality.
