Abstract:
1. A device, comprising: a first conductive layer deposited over a substrate; an active layer deposited over said first conductive layer and configured to convert electrical energy to light; a second conductive layer having a first surface overlying said active layer and a second surface opposite to said first surface; an electrically conductive and optically transparent or semi-transparent layer having a first surface and a second surface, wherein said first surface of said electrically conductive and optically transparent or semi-transparent layer directly or indirectly overlies said second surface of said second conductive layer, wherein said second surface of said electrically conductive and optically transparent or semi-transparent layer includes a pattern having a plurality of pre-defined geometric shaped thick regions and a plurality of thin regions, wherein the plurality of thin regions occupies approximately fifty percent (50%) of the pattern, wherein said plurality of pre-defined geometric shaped thick regions are configured to distribute at least a portion of electric current to said plurality of thin regions; a first electrode coupled to said second surface of said electrically conductive and optically transparent or semi-transparent layer; and a second electrode coupled to said first conductive layer.
