    摘要： Disclosed herein is method of operating a device that comprises an array of micromirrors. The method comprises a process usable for repairing stuck micromirrors of the micromirror array during the operation. The reparation process applies, at the ON state, two consecutive refresh voltages to the mirror plates of the micromirrors in the array with the pulses being separated in time longer than the characteristic oscillation time of the micromirrors. The reparation process can be applied independently to the micromirrors. Alternatively, the reparation process can be incorporated with a bias inversion process.

    摘要： The present invention provides a method and apparatus of converting a stream of pixel data representing an image in the first orientation in space and time into a stream of bitplane data representing an image in the second orientation. The second orientation can be a horizontal, vertical, or a combination of thereof of the first orientation. The method of the invention can be performed in a “real-time” fashion, and dynamically performs predefined transformation, or alternatively performed in by a functional module implemented in a computer readable medium stored in a computing device.

    摘要： The invention provides a method and apparatus for evaluating the product quality and performances of micromirror array devices through measurements of the electromechanical responses of the individual micromirrors to the driving forces of electric fields. The electromechanical responses of the micromirrors according to the present invention are described in terms of the rotational angles associated with the operational states, such as the ON and OFF state angles of the ON and OFF state when the micromirror array device is operated in the binary-state mode, and the response speed (i.e. the time interval required for a micromirror device to transit form one state to another) of the individual micromirrors to the driving fields.

    摘要： A method and apparatus of the present invention is particularly for use in display systems having spatial light modulators in which the pixels present asymmetrical switching delays. For a desired illumination intensity of a pixel, a series of pulse-width-modulation bit values for the pixel is determined based at least in part upon a parameter that characterizes the asymmetrical transition behavior of the pixel between states.
