Abstract
In a matrix display of light reflecting elements, each element is duty cycle modulated into one of two states represented by successive bits of a digital display code to produce a luminance level represented by the code. In order to correct a visual artifact which occurs when the human eye views the element during only part of the modulation cycle for the code, the element is repeatedly sequentially activated for short periods into optical states represented by the most significant bits of the code.
