Abstract
A projection display system having a projector, the projector includes a laser light source, a lighting system, and a control circuit. The laser light source has a first laser light source module and a second laser light source module. The first and second laser light source modules provide laser light. The lighting system converts the laser light into image light for displaying an image. The image light includes first polarized light and second polarized light. The control circuit controls the laser light source and the lighting system. The control circuit independently controls the light energy output by the first and second laser light source modules to change the intensity of the first and second polarized light.
