ABSTRACT:
A digital printer for printing images in response to full-frame, two-dimensional digital image data input from an outside source. The digital printer is a novel combination of a two dimensional backlight for producing full frame illumination in a single flash, a photoreceptor sensitive to light emanating from the backlight, a two-dimensional, transmissive light valve, an imaging system, and a driver. The light valve is disposed between the backlight and the photoreceptor so that light from the backlight is transmitted through the light valve, producing a full-frame, two dimensional image on the photoreceptor in response to a single flash of the backlight. The full-frame, two dimensional image corresponds to a pattern formed on the light valve in response to the full-frame, two dimensional digital image data. The imaging system is disposed between the light valve and the photoreceptor, such that it focuses the full-frame, two dimensional image onto the photoreceptor. The driver is coupled to the light valve, the backlight and the outside source. The driver couples the full-frame, two dimensional digital image data from the outside source to the light valve. The driver also synchronizes the backlight with the light valve such that the backlight flash exposes the light valve after the pattern is set on the light valve in response to the full-frame, two dimensional digital image data.
