Abstract
A scanning image display system which includes a plurality of scanning image displays each including a light source adapted to emit a laser beam, and a scan unit having a first scan section adapted to scan the laser beam emitted from the light source in a first direction on a projection surface, and a second scan section adapted to scan the laser beam in a second direction substantially perpendicular to the first direction. The first scan sections are resonant scan sections which are faster than the second scan sections in scan speed. The first scan sections are heated with light during the time that an image is formed and a reset period of the second scan sections in order to control resonant frequencies of the first scan sections.
