Patent ID: 7427782

Claim:
A light active sheet comprising: a bottom substrate flexible sheet having an electrically conductive surface; a top transparent substrate flexible sheet having a transparent conductive layer disposed thereon; an electrically insulative adhesive flexible sheet; light active semiconductor elements fixed to the electrically insulative adhesive sheet, said light active semiconductor elements each having an n-side and a p-side, the electrically insulative adhesive sheet having the light active semiconductor elements fixed thereon being inserted between the electrically conductive surface and the transparent conductive layer to form a lamination and activated so that the electrically insulative adhesive electrically insulates and binds the top substrate sheet to the bottom substrate sheet so that one of said n-side or said p-side of the light active semiconductor elements is in electrical communication with the transparent conductive layer of the top substrate sheet and so that the other of said n-side or said p-side of each said light active semiconductor element is in electrical communication with the electrically conductive surface of the bottom substrate sheet to form a light active device, wherein the bottom substrate, the electrically insulative adhesive and the top substrate are provided as respective rolls of material; and the step of inserting comprising bringing the bottom substrate, the electrically insulative adhesive and the top substrate together in a continuous roll fabrication process.
