COLOR DISPLAY DEVICE AND CIRCUITRY FOR ADDRESSING THE LIGHT VALVE OF SAID DEVICE |
摘要 |
<p>A color projection video system utilizing only a single light valve. A white light source is separated into red, green and blue bands. Scanning optics cause the RGB bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of panels on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. The sequence of lightbands occurs so quickly as to give the viewer an appearance of simultaneous full color. <IMAGE></p> |
