ABSTRACT:
An image display system includes an improved hinge for a micro-mirror device composed of a conductive-doped semiconductor and immune to plastic deformation at typical to extreme temperatures. The hinge is directly connected to the micro-mirror device and facilitates the manufacturing of an optically flat micro-mirror. This eliminates Fraunhofer diffraction due to recesses on the reflective surface of the micro-mirror. In addition, the hinge is hidden from incoming light thus improving contrast and fill-factor. The image display system further includes signal transmission metal traces formed on areas between the doped semiconductor hinges. The signal transmission metal traces are formed either before or after a high temperature crystallization process is applied to the hinges.
