  • Publication number: 20150301346
    Abstract: A light source module for stereoscopic display includes multi-primary color lasers which output the light with the same polarization direction. Respective lasers are divided into two groups according to the wavelengths of the output light. A light combiner is provided in the output light path of each laser group and is used for combining the output light of all lasers in the group into one output light path. The light source module further includes a polarization conversion rotary member, and the polarization direction of the two output light is periodically and alternately rotated by 90 degree by self-rotation of the polarization conversion rotary member. An imaging device for stereoscopic display includes the light source module for stereoscopic display, the light combiner and a first optical imaging modulator and a second optical imaging modulator. A stereoscopic display system includes the imaging device for stereoscopic display and a projection lens sub-system.
