摘要：A display and a driving method for the same capable of constructing clear visualimages is described. In the display, a plurality of conductive pads are opposed to a back

electrode with a light influencing medium, such as a liquid crystal layer, disposedtherebetween. Control signals are supplied to the conductive pads throughcomplementary transistors comprising a p-channel field effect transistor and an n-channel field effect transistor connected between VDD and VSS lines of a control circuit,which also supplies a bias voltage to the back electrode and gate control signals to thegate terminals of the p-channel field effect transistor and the n-channel field effecttransistor. During operation, the bias voltage is inverted in order to invert the polarity ofcontrol signals applied across the light influencing medium.
