ABSTRACT:
A projector includes a light diffusing unit that is vibratably provided to diffuse incident light by a vibration and to emit diffused light, the light diffusing unit having a unique resonance frequency, a vibration generating unit that has a piezoelectric element for vibrating the light diffusing unit, and a control unit that controls the vibration generating unit to vibrate the light diffusing unit at a frequency corresponding to the unique resonance frequency of the light diffusing unit. An image is displayed using the diffused light emitted from the light diffusing unit.
