Abstract
In a display device in which one dimensional light emitted from a light emitting element driven by an image signal generating device is scanned by moving a reflecting member so as to provide a two-dimensional image to an observer utilizing after image phenomenon, in order to prevent variation in an amplitude or variation of the center of vibration of the reflecting member which may cause image deviation, angle of displacement of the reflection member is detected by a detector, a position signal from the detector is compared with a reference signal and based on the result of comparison, the image signal generating device is controlled.
