Abstract
A calibration method for a grating light modulator includes calibrating light reflective ribbons on the modulator on a pixel-by-pixel basis. The method further includes performing a dark-state calibration and a bright-state calibration for each pixel. Once completed, the results of the dark-state calibration and the bright-state calibration may be combined to ensure a smooth transition between a dark state and a bright state for each pixel.
