Abstract
A mobile display apparatus using an optical modulator is disclosed, comprising: a sensor sensing a light reflected from a side of a scanning device and then generating a scanning device reference signal specifying a position of the scanning device; and a driving signal control unit generating such scanning device control signal and optical modulator control signal that allow a light emitted from an optical modulator to be reflected in a predetermined area of the scanning device, by synchronizing the scanning device reference signal transferred from the sensor with an image synchronization signal.
