A projector to be simple and capable of being miniaturized. White light is decomposed by a color decomposition/composition device into red light, green light, and blue light, which are incident to a first, second, and third mirror deflection type light modulators and first effective reflected light to third effective reflected light obtained by the first, second, and third mirror deflection type light modulators are composed together, so that color decomposition/composition can be performed by the color decomposition/composition device eliminating the necessity of separately provided color decomposition and composition optical systems, and consequently it is possible to construct the optical system with ease, thereby realizing a projector which is simple and can be miniaturized.
A sequential color display system using three spatial light modulators and dichroic filters to sequentially provide a primary color light beam to a projection spatial light modulator. A set of dichroic filters separates a white light beam into primary colored light beams. Each primary colored light beam is modulated by a spatial light modulator to selectively allow it to travel to a second set of dichroic filters. The second set of dichroic filters recombines the primary color light beams--only one of which is typically active at any given time--to form a sequential color light beam. A projection spatial light modulator selectively modulates the sequential color light beam to form a sequential color image projected onto an image plane.
A field sequential color projection display system, which has high brightness, high accuracy and compact size, and is light and energy saving. The field sequential color projection system comprises: a field sequential beam splitting/combining light valve module including three light valves, which can be controlled by applied energy field, for outputting polarized light of three primary colors in time sequence; a frame sequential display module for respectively displaying frames of three primary colors corresponding to the polarized light of three primary colors output in time sequence, wherein the polarized light passes through the frame sequential display module; a projection lens module for projecting the polarized light passing through the frame sequential display module onto a screen to produce a full color image.
A projecting display system includes a light source (101) which produces light which is spatially modulated by a number of spatial light modulators (105, 107). A splitting means (103) is provided in the light path between the light source (101) and the spatial light modulators (105 and 107) such that the overall luminous flux produceable by the system is not determined by the maximum luminous flux which each spatial light modulators (105, 107) can accommodate.
A multi-array spatial light modulating (SLM) device and methods of fabricating such a device. The multi-array SLM device includes a number of addressable arrays of elements, and each of the addressable arrays is capable of modulating light to generate an image.
