Driving circuit adaptable to an electrophoretic display

Abstract

A driving circuit adaptable to an electrophoretic display includes a first transistor and a second transistor electrically connected in series between a first positive voltage node and a first negative voltage node, the first transistor and the second transistor being interconnected at an output node; a third transistor electrically connected between the output node and a ground; a first voltage regulator that switchably provides one of a plurality of positive supply voltages to the first positive voltage node; a second voltage regulator that provides a negative supply voltage to the first negative voltage node; a switching circuit having a plurality of outputs electrically connected to the first transistor, the second transistor and the third transistor to turn on or off the first transistor, the second transistor and the third transistor respectively; and a controller that controls the first voltage regulator, the second voltage regulator and the switching circuit.
