ABSTRACT:
A printer includes an active matrix liquid crystal display (AMLCD) light valve with a matrix of a plurality of filter elements, a backlight that emits a plurality of wavelengths of electromagnetic energy that correspond to the plurality of filter elements, and a multi-layer photoreceptor that is sensitive to the plurality of wavelengths of electromagnetic energy. The backlight flash exposes the AMLCD light valve. The distinct wavelengths of electromagnetic energy passing through each of the filter elements of the AMLCD light valve are focused onto the surface of the photoreceptor. Each layer of the photoreceptor is sensitive to only one of the distinct wavelengths of electromagnetic energy passing through the filter elements of the AMLCD light valve. Thus, a full color latent image is flash exposed onto the photoreceptor. A very compact lenslet array is used to focus the image onto the photoreceptor. This reduces the overall space requirements of the printer, making it readily suitable for desktop applications.
