Abstract
A display apparatus may be constructed by imparting motion to the light from a small light source to give the appearance of a line, causing the light to be 'off' and 'on' as desired during traverse of a line length, using as many light sources as needed for a two-dimensional display and precorrecting the light timing to compensate for the apparent change in movement rate during the motion.
