摘要： A liquid crystal element, a packaging structure providing thermal and alignment control, a display device including the same, and methods of fabrication and assembly are provided. The liquid crystal element includes: a semiconductor wafer, having microcircuitry and an array of reflective pixels; a layer of electro-optical responsive liquid crystal medium, of uniform thickness, disposed on the reflective pixels; a transparent conductive layer positioned on the liquid crystal, being substantially parallel to the reflective layers, to ensure a uniform thickness of the liquid crystal; and an insulative transparent layer provided on the conductive layer. The liquid crystal element is laminated to an optically flat substrate to limit the out-of-plane distortions thereof. The structure formed by element and substrate are disposed in a substrate holder which is mounted to a wiring board, and coupled to voltage sources for actuating the liquid crystal. During mounting, an aligning fixture is used to ensure proper orientation of the element relative to the related optical elements. Once the element is positioned, a heat sink is coupled to the rear surface of the substrate holder to dissipate heat.

摘要： The present invention builds a metal electrode that is controlled by the common electrode in each pixel cell. During operation, a voltage is first applied to this metal electrode to transform the liquid crystal molecule over this metal electrode from the splay state to the bend state. Next, a voltage is applied to the pixel electrode to transform the liquid crystal molecule in the whole pixel region from the splay state to the bend state.

摘要： A liquid crystal (LC) lightvalve comprising a twisted nematic LC layer whose molecules are aligned with pixel edges at the mirror backplane, thereby providing improved contrast and efficiency, and reduced visibility of post spacers in black state. The present invention is directed to an LC structure wherein the backplane is rubbed in a direction rectilinear with pixel edges. The LC layer is given the same twist rotation and birefringence as in the conventional TN lightvalve. Polarization control is maintained by illuminating the lightvalve with light whose polarization is rotated by the twist angle relative to the x,y, pixel axes, and by collecting the orthogonally polarized component of the reflected light. The lightvalve top glass is thus rubbed in a direction which is rotated by the twist angle from the horizontal or vertical direction at which the backplane is rubbed.
