Abstract
A method and system for compensating for defects in a multi-light valve display allows for the compensation of defective pixels in a display. By sequentially illuminating all light valves in a multi-light valve system with all colors, or wavelengths, available in the display, each light valve modulates the full gamut of colors available in the system. In this manner, the remaining light valves can compensate for a defective pixel in one of the light valves. The invention also includes an active compensation feature, whereby defective pixels in the display are identified and are compensated for by an associated display driver.
