Abstract: When producing an image in an optical scanning device, such as an optical scanning device employing pulse width modulation, for example, a pixel or its adjacent pixels are illuminated over a period at least as a function of a sequence of illumination data. Such pixel or its adjacent pixels are illuminated, however, at different locations within the pixel or its adjacent pixels over the period. This varying of the illumination-location within pixels over time reduces the “screen-door effect” present in conventional displays.
