Abstract
A multi-DMD projection system uses an extended X-cube color splitting/recombining prism to implement splitting and recombining functions at different sections of the cube. Light directed from a white light source is split into red, green and blue components in a lower section of the cube. The components are directed to respective first, second and third DMDs for separate modulations and reentered into the X-cube prism by TIR prism for recombining at an upper section of the cube.
