Abstract
In a scrolling color projection system for displaying images represented by continuously updated frames of information, eg., video images, and employing a single, reflective electro-optic light modulator such as an AMLCD, flicker in the image caused by asymmetric electrical behavior of the light modulator is reduced without substantially reducing the brightness of the display, by addressing the modulator array at least twice during each frame period.
Claims12
A display system for displaying continuously updated image information signals arranged in successive frames representing full color frames, the system employing a reflective electro-optic light modulator comprised of a row-and-column matrix array of pixels, for modulating light in accordance with the image information signals during successive frame periods, and means for addressing the array with the image information signals, wherein each row of the array is addressed at least twice during each frame period.
