SEQUENCIAL COLOUR ILLUMINATION IN DISPLAY SYSTEMS EMPLOYING LIGHT MODULATORS

摘要

The present invention provides an illumination system (101) for providing sequential colour light beams for display systems (100) employing light modulators. The illumination system (101) comprises a light source (102), a lightpipe (104), and a colour filter (106) that is positioned after the lightpipe (104) on the propagation path of the illumination light such that primary colour light beams shining on the light modulator have defined boundaries during colour transition periods.
