ABSTRACT:
A linear array of liquid crystal shutters mounted near a photoreceptor surface and arranged transversely to the direction of travel of the photoreceptor surface, an array of thin film transistors connected to the array of liquid crystal shutters for electrically driving the shutters and logic means connected to the array of thin film transistors selectively pulsing the liquid crystal shutters to selectively expose the photoreceptor surface a line at a time. The system further includes circuit means for producing an electric field between the opposed electrodes of each of the liquid crystal shutters to prevent passage of light through the shutters and means for selectively de-energizing each of the pairs of electrodes for predetermined time period in response to the receipt of input data signals.
