ABSTRACT:
A scanning display device directly scans a light source along at least one scanning path, rather than scanning a light beam emitted from such source along such scanning path. By scanning the light source a smaller, lighter weight scanner without a mirror can be used to achieve light source scanning along the desired scan path. A resonant cantilever translates one or more point sources (e.g., one for a monochromatic display; red, green and blue for an RGB display). The cantilever motion is driven by an electromagnetic drive circuit or by a piezoelectric drive actuator. The light source is one or more light emitting diode point sources, one or more a fiber optic point sources, or one or more light emitting polymer light sources.
