摘要： 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.

摘要： In active driving of liquid crystal panels (R, G, and B) corresponding to R, G, and B color by X shift registers (R, G, and B) and Y shift registers (R, G, and B), alternating-current driving is performed such that signals to be written to the R color and B color liquid crystal panels are opposite in polarity to a signal to be written to the G color liquid crystal panel and also Vcom voltage of each of the liquid crystal panels is adjusted to thereby reduce flicker. The Vcom voltage supplied to the B color liquid crystal panel, for example, is finely adjusted to reduce flicker of a synthetic image of the liquid crystal panels.

摘要： In an image display system capable of displaying an M.times.N number of pixels based on optical projection, a light source emits a white light, the white light being reflected on a total mirror at a predetermined angle. An optical filter splits the white light reflected from the total mirror into a trinity of primary light beams, i.e., a red, green and blue light beam. Each of a trinity of arrays of M.times.N actuated mirrors generates an optical pixel signal by reflecting the primary light beams impinging thereon, each of the actuated mirrors in the arrays being capable of changing the optical path of the primary light beams reflected therefrom, wherein a driver circuit controls each actuated mirror based on an input image signal. A projection stopper partially transmits the optical pixel signal and a projection screen displays the optical pixel signals passing through the projection stopper.

摘要： A projective display system includes a light source, a display surface, and a two dimensional light modulator array in an optical path between the light source and the display surface. The two dimensional light modulator array has a plurality of light modulators arranged in rows to modulate light from the light source, with at least one row being susceptible to failure. To compensate for any failed rows, an optical element redirects modulated light from presenting a first row of virtual pixels on the display surface to substantially occupy a second row of virtual pixels on the display surface. In conjunction with various image processing techniques for deblurring, this permits partial or complete correction for faulty rows of light modulators.

摘要： A spatial light modulator in the form of a deformable mirror device receives from a frame store data which has been formatted by a data formatter subsequent to gamma correction in a ROM look-up table. The DMD displays different light levels by being ON for selected periods of a series of durations 4, 8, 16, - - - , 1024 varying in proportion to a basic period multiplied by powers of two. The shortest duration 4 for which the DMD can be turned on is a multiple of the basic period, and the series includes additional durations 5, 6, and 7 in the series between the shortest displayable duration 4 and the next power of two 8. Durations 1, 2, and 3 of less than the shortest displayable duration can be displayed by adjusting the turn-on time of a proportion of the adjacent mirrors. The longest duration for which the mirror can be turned on can be employed twice.

摘要： A color video projector system has separate light sources for producing separate beams of light which are passed each first through color filters to provide separate color beams before being processed by video-controlled light shutter matrices and then combined into a single beam projectable to provide a full-color video display with superimposed color spots rather then side-by-side color spots. In a preferred embodiment the color beams are red, green, and blue.
