1. A method for dark noise reduction in pulse width modulated (PWM) displays, comprising steps of: measuring brightness level differences between adjacent pixels in successive frames of video data; establishing a pixel brightness level threshold; defining said pixels in said successive frames of video data as bright image pixels or dark image pixels with respect to said brightness level threshold; for said successive frames of video data, separating said bright image pixels from said dark image pixels; generating from said dark image pixels first and second sets of corrected pixels having brightness levels corrected in accordance with said brightness level differences between adjacent pixels in successive frames of video data; combining said first set of corrected pixels, said second set of corrected pixels and said bright image pixels to form successive frames of corrected video data; and, displaying video images responsive to said successive frames of corrected video data.
