In a method of manufacturing an organic electroluminescent display, a substrate, in which a plurality of pixel areas is defined, is prepared, and first electrodes are formed in the pixel areas. The detectors operate on streams of image data, making them suitable for detecting certain types of patterns in documents and images passed between processes and devices. Further, the micro-devices andor micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds.
