A scanned video display system in which a stress wave propagating medium forms a viewing plane and scanning is accomplished in a first scanning direction by stress waves propagated along the medium, while scanning in a second scanning direction is accomplished by emitting light along a scan line in the second direction. The light emitted along the scan line in the second direction is modulated in intensity by a video signal and is incident upon each of the stress waves over the extent of the viewing plane so as to produce a video modulated beam of light scanned in the two dimensions or directions of the viewing plane. In one embodiment, the emitted light is polarized in a first direction and passes through the stress wave propagating medium. The light is again polarized after passing through the medium but in a direction orthogonal to the first direction. In another embodiment, a surface of the medium is reflective and the emitted light is parallel to the reflective surface of the medium such that the light strikes the propagated wave and is reflected away from the surface of the medium. A color embodiment and parallel output feature are also disclosed.
