<p>PROBLEM TO BE SOLVED: To improve a gray scale and resolution by converting a video signal into signal charges and transmitting them to respective pixels, and reflecting light on a specific position on a screen for a time which is proportional to the amount of the signal charges. SOLUTION: The CCD consists of transmission channels 42 which are arranged horizontally and vertically and horizontal and vertical transfer electrodes 46 and 48 which are formed thereupon, and a pixel is composed of a capacitor 52 which stores signal charges from the transmission channels 42, a reflecting plate 58 which determines a reflection time according to the amount of accumulated signal charges, a base 56 which determines the maximum tilt angle of the reflecting plate 58, and a charge reset which decreases the signal charges as the time passes. Then an input part converts the inputted video signal into electric charges, and the CCD is controlled by a clock and transmit the converted electric charges to respective pixels, which irradiate specific positions on the screen with the light reflected by the reflecting plate 58 for a necessary time.</p> |
