ABSTRACT:
A reflection type display device wherein the brightness of pixels is controlled by deflecting a reflecting surface corresponding to a pixel in the reflection type display device for a time proportional to a charge transmitted to the pixel. A reflecting surface capable of deflection is charged and a region adjacent the reflecting surface is charged with an initial charge which is proportional to the desired brightness of the pixel and of sufficient magnitude and polarity to deflect the reflecting surface to a reflection angle. The region adjacent the reflecting surface is discharged so as to maintain the magnitude of the charge of the region adjacent the reflecting surface above the magnitude of charge sufficient to deflect the reflecting surface so that the reflecting surface remains deflected for the time corresponding to the desired brightness of the pixel.
