Abstract
One embodiment disclosed relates to a method for bi-directional progressive scanning in a display system. The method includes receiving image data for an image to be displayed, forward scanning the image data in a first direction using a linear array of controllable light elements, and reverse scanning the image data in a second direction opposite to the first direction using the linear array. Another embodiment disclosed relates to an apparatus for bi-directional progressive scanning. The apparatus includes a linear array of controllable light elements, and a scanner driver that drives a scanner apparatus using a drive signal that is applied to drive both forward and reverse optical scanning of an image by the linear array.
