Abstract
An electroluminescent apparatus includes a protection layer characterized by two or more non-overlapping regions and a back electrode layer which includes two or more back electrode regions. Each of the back electrode regions overlies a corresponding one of the non-overlapping regions in the protection layer. A bottom insulation layer includes two or more bottom insulation regions, each of which overlying a corresponding one of the back electrode regions. The apparatus includes two or more electroluminescent segments, each of which overlying a corresponding one of the back electrode layers. A transparent electrode layer includes two or more transparent electrode regions, each overlying a corresponding one of electroluminescent segments. The apparatus includes two or more power supply devices, each of which coupled to a corresponding one of the back electrode regions and to a corresponding one of the transparent electrode regions for providing luminescence over a corresponding one of the non-overlapping regions.
