Abstract
A two-channel field sequential display system utilizes both simultaneous and sequential color display methods to display full color images in a way that is less complex, smaller in size and less costly than prior art additive color systems, while exhibiting higher light output and fewer temporal visual effects than prior art single-channel field sequential color display systems. The two-channel field sequential display system displays two of three primary colors that make up the image simultaneously during a portion of a display frame and displays the third primary color sequentially during a subsequent part of the display frame. The two-channel field sequential color display concept may be applied to any projection system which combines individual monochrome projector outputs to form an image on a screen or to any display technique that is capable of superimposing two images. The projectors can be implemented with any reflective or transmissive light valve based projection system, or any appropriately color modulated emissive source.
