Abstract
Device structures for sheets of light active material. A first substrate has a transparent first conductive layer. A pattern of light active semiconductor elements are fixed to the first substrate. The light active semiconductor elements have an n-side and a p-side. Each light active semiconductor element has either of the n-side or the p-side in electrical communication with the transparent conductive layer. A second substrate has a second conductive layer. An adhesive secures the second substrate to the first substrate 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 second conductive layer. Thus forming a solid-state light active device.
