DISPLAY SYSTEM

摘要

44 The present invention is directed to display systems, useful for projection video and television systems, performing with high efficiency and good color rendition. In these systems, color may be provided, as one example, by various light valves, such as liquid crystal displays, each of which are positioned at equal path distances from an illuminating subsystem, as well as having equal path distances from the light valves to a projection subsystem. This enables optimum illumination of each of the light valves. Various embodiments of arranging the light valves, as well as providing illumination are described.
