  • Piezoelectric light shutter
    Patent number: 5781333
    Abstract: A piezoelectric actuatable array of light shutters is disclosed wherein each pixel aperture in the array is selectively opened and closed by way of an opaque piezoelectric shutter. Upon application of a voltage, each piezoelectric shutter extends laterally so as to close the corresponding pixel aperture and prevent light from passing therethrough. The pizeoelectric shutters contract, opening the corresponding pixel aperture, upon removal of the above-threshold voltage.
