Abstract

PURPOSE: To accomplish a high-quality and uniform picture display all over a picture element by synthesizing light beams emitted from three light emitting bodies having different color respectively to one point, performing two-dimensional scanning with the synthesized light beam and displaying a two-dimensional image.
CONSTITUTION: A light emitting body driving means 2 fetches picture element data 102, 103 and 104 according to a picture element data transfer control signal 105 and allows a light emitting means 3 to emit the light beam in timing that a light emitting timing signal 101 is given. The light emitting means 3 is constituted of three light emitting bodies 4 which output red, green and blue, and the respective light emitting bodies 4 emit the light beams according to the data 102, 103 and 104. An image-formation optical means 5 receives the respective output light beams from the means 3, synthesizes them to the spot light corresponding to one picture element and forms an image. A 1st deflecting means 6 controls its deflection angle like a galvano mirror or a polygon mirror by a synchronizing control means 8 so as to perform linear scanning with the spot light. This action corresponds to horizontal scanning by comparing to a CRT.
