    • A thin low power, paper white, direct-view display includes an array of bistable micromirrors that are deflected between two stable states, a dark state in which the mirror covers a portion of the background and a white state in which the mirror uncovers the background. The drive electronics are similar to those used in multiplexed LDCs but are modified in order to drive the micromirrors to one of their two stable states. The micromirrors in the enabled row are attracted up or down with sufficient force to exceed the micromirrors' bistable threshold and deflect the micromirrors to their dark and white states, respectively. The attractive forces on the micromirrors in the remaining non-enabled rows are insufficient to exceed the micromirrors' bistable threshold so that the micromirrors remain in their current stable state.

    • The present invention provides a Schlieren projection system with a large aperture reflective imager. The combination of a beam-addressed CCM design with flat-panel manufacturing techniques configuration produces a large aperture imager that overcomes the problems of limited deflection range, high beam current, electrostatic instability and limited resolution associated with known electrostatically-actuated micromirror targets. The CCM imager includes a thin insulating membrane that decouples the electron beam from the micromirror array. Decoupling also allows the mirror to be designed to optimize reflectivity, exhibit a higher resonant frequency for better video performance, and be fabricated simultaneously with the hinges. The CCM imager is fabricated using flat-panel manufacturing techniques that are ideally suited to producing large aperture devices at low cost.
    • 本发明提供了一种具有大孔径反射成像器的施利伦投影系统。 光束寻址CCM设计与平板制造技术配置的组合产生大孔径成像器,其克服了有限的偏转范围,远光束电流,静电不稳定性以及与已知的静电致动微镜靶相关的有限分辨率的问题。 CCM成像器包括使电子束与微镜阵列分离的薄绝缘膜。 去耦还允许将反射镜设计成优化反射率,展现更高的谐振频率以获得更好的视频性能,并与铰链同时制作。 CCM成像仪采用平板制造技术制造,非常适合以低成本生产大孔径器件。
