摘要： A micromirror device, which makes an image display with digital image data, comprises pixel elements each of which makes pulse width modulation for incident light depending on the deflection state of light and which are arranged in the form of an array. The array of the pixel elements is composed of B subsets each including pixel elements of Ms (COLUMNs)×Ns (ROWs) (Ms, Ns, and B are natural numbers). Each of the pixel elements has a mirror, and at least one memory cell. The memory cell has a transistor of an input gate capacity Ct[F]. Each memory cell is connected by a ROW line having a wiring resistance R[Ω], and a wiring capacity C[F].

摘要： A micromirror device with a lower driving voltage is disclosed. The lower driving voltage is achieved by projecting a partial light for image display during a micromirror is oscillating from fully on state to a fully off state. The micromirror device includes a reflective element supported on a hinge for oscillating and positioning at least three states. These three states are a fully on state, a fully off state, and a partially ON angular positions in responding to a digital control signal. The oscillation of the micromirrors is controlled in responding to a digital control signal wherein the digital control signal is controlled for writing into display pixels in an interleave-and-jump sequence to jump multiple lines to non-sequential lines of a display image.

摘要： 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.

摘要： An alignment system for aligning the print plates of a two-sided contact printing station includes expanding pin assemblies each having an expanding collet and a mandrel for engaging and aligning match drilled holes in each of the print plates. An expansion cylinder moves the mandrel into and out of engagement with the expanding collet to cause the collet to expand into engagement with the match drilled holes. The outside profile of the expanding collet forms a straight-pin diameter which corresponds to the diameter of the match drilled holes when expanded. The expanding pin assemblies may be contracted to facilitate moving the print plates apart for advancing the working material.
