PROJECTION DISPLAY SYSTEM

摘要

A liquid crystal display system comprising: a. a dichroic mirror (2) arranged to direct first and second spectral components along a first processing path (A) and to direct a third spectral component along a second processing path (B); b. a first cubic polarizing beam splitter (4) arranged to direct the first and second components towards first and second liquid crystal on silicon (LCoS) panels (18, 22), respectively, and to direct the first and second components, after modulation, along a third processing path (C); c. a second cubic polarizing beam splitter (6) arranged to direct the third component towards a third LCoS panel (28), and to direct the third component, after modulation, along a fourth processing path (D); d. a cubic dichroic beam splitter (8) arranged to direct said first and second components and said third component along a fifth processing path (E); and e. three post analyzers (30, 32, 34) arranged on an external output face of the dichroic beam splitter.
