ABSTRACT:
A liquid crystal light pipe display for direct imaging onto photosensitive materials, having a non-conductive, transparent first sheet and a non-conductive substantially opaque second sheet, each having substantially planar inner and outer surfaces. The non-conductive sheets are disposed adjacent to one another with their inner surfaces opposing one another in spaced-apart relationship separated by a sealed-in, normally transparent, liquid crystal material. The non-conductive sheets each have a transparent conductive electrical coating disposed on their inner surface, of a plurality of discrete character forming segments with means connected thereto for electrically coupling said segments to an external power source. The second non-conductive sheet has a plurality of discrete transparent light pipes formed therethrough, each of which are aligned with one of said character forming segments. First and second linear polarizer sheets are secured to the outer surface of said first non-conductive sheet and to the outer surface of the second non-conductive sheet.
When the adjacent character forming segments are actuated by the power source, light from an external light source is transmitted through the liquid crystal element and through each of the corresponding light pipes for direct imaging onto photosensitive materials. The display may be a single row of dots capable of scrolling images onto the moving photosensitive drum of a photocopy machine, or a full screen of rows and columns of dot matrices for creating a full display of images onto planar photosensitive materials.
