Abstract
An apparatus for driving an electro-optic display may comprise a first switch designed to supply a voltage to the electro-optic display during a first driving phase, a second switch designed to control the voltage during a second driving phase and a resistor coupled to the first and second switches for controlling the rate of decay of the voltage during the second driving phase.
