Abstract

Generally, the present disclosure relates to illumination modules and image projectors using the illumination modules. The present disclosure provides a technique to reduce the degradation of the reflective polarizer used in such illumination modules, and therefore can lead to improving the total efficiency of an image projector without undue lifetime limitations.
