Disclosed herein are a system and apparatus for operating a device that comprises an array of micromirrors. The system and apparatus are usable for repairing stuck micromirrors of the micromirror array during the operation. The reparation 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 can be applied independently to the micromirrors. Alternatively, the reparation can be incorporated with a bias inversion process.

Method of repairing micromirrors in spatial light modulators

A method and apparatus for operating spatial light modulator have been disclosed herein. The spatial light modulator comprises an array of micromirror devices, each of which further comprises a reflective deflectable mirror plate attached to a deformable hinge, and an addressing electrode for addressing and deflecting the mirror plate.

Deflection mechanisms in micromirror devices

A method and a color rendering filter for compensating for deficiency in illumination light from a light source in display systems are provided. The color rendering filter has a color that is determined based upon the spectrum, sensitivity of viewer's eyes over the visible light range, and a pre-determined waveband threshold.

Color rendering of illumination light in display systems

A method and apparatus for compensating for deficiency in the illumination light from a light source is provided, where the spectrum in the visible range of light from the light source is determined, and a deficiency at a wavelength or band of wavelengths in the visible range of light is determined therefrom, a color sequencing device is provided having a set of filters comprising red, green and blue filter segments, and an additional color balancing filter segment, and wherein a the color balancing segment is constructed so as to preferentially pass a band or bands of wavelengths, which band or bands are determined based on the determined deficiency of the light source.

A method for generating an updated path metric includes combining each of first and second provisional path metric first portions with an associated branch metric first portion to produce a first provisional updated path metric first portion candidate and a second provisional updated path metric first portion candidate, respectively. The method also includes selecting one of the provisional first portion updated path metric candidates to produce an updated path metric first portion candidate and combining any carry component of the selected updated path metric first portion candidate with a path metric second portion and a branch metric second portion to produce a first updated path metric second portion candidate. The method also includes comparing the updated path metric second portion candidate to at least one other updated path metric second portion candidate; and selecting one of the updated path metric second portion candidates to produce an updated path metric second portion.
