1. A device for displaying an image having first and second image portions in response to an image signal, comprising: a scanning mirror mounted for periodic motion through a selected scanning angle; a driver coupled to the scanning mirror and operative to sweep the scanning mirror through the selected scan pattern; a first light source responsive to a first input signal to emit a first modulated light beam along a first light path relative to the first light source, the first light source being oriented such that the first light path strikes the scanning mirror at a first angle at which the scanning mirror reflects the first modulated light beam to a first image region in which the first modulated light beam defines the first image portion; a second light source responsive to a second input signal to emit a second modulated light beam along a second light path relative to the second light source, the second light source being oriented such that the second light path strikes the scanning mirror at a second angle at which the scanning mirror reflects the second modulated light beam toward a second image region in which the second modulated light beam defines the second image portion, and wherein the orientation of the first and second light sources is selected such that the first and second regions are substantially non-overlapping, and electronic control circuitry having an input port for receiving the input signal and first and second outputs coupled to the first and second light sources respectively, the control circuitry being responsive to the image signal to produce the first and second input signals.
