ABSTRACT:
A display and a driving method for the same capable of constructing clear visual images 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. Control signals are supplied to the conductive pads through complimentary transistors comprise a p-channel field effect transistor and an n-channel field effect transistor connected between VDDand VSSlines of a control circuit, which also supplies a bias voltage to the back electrode and gate control signals to the gate terminals of the p-channel field effect transistor and the n-channel field effect transistor. During operation, the bias voltage is inverted in order to invert the polarity of control signal applied across the light influencing medium.
