  • Device for high resolution recording of liquid crystal display images
    Patent number: 4782348
    Abstract: A photosensitive recording medium is arranged in contact with the outside surface of a curved liquid crystal display cell forming a partial or complete cylinder. Both the liquid crystal display cell and the photosensitive member are arranged concentric to the axis of a linear radiation source. The linear radiation source is segmented by a number of nonreflective fins along its length. By controlling the radius of the cylinder or cylindrical section, the thickness of the liquid crystal display cell, the diameter of the linear radiation source and the spacing and depth of the segmentation fins surrounding the radiation source, a projection of the image displayed on the liquid crystal display cell may be obtained and recorded on the surface of the photosensitive medium with sufficient resolution to enable high resolution recording of the displayed information.
