Abstract
A thin film transistor (TFT) backplane comprising a plurality of electrodes. Each of the plurality of electrodes is coupled to circuitry comprising: a first thin film transistor (TFT) coupled to the electrode for transmitting waveforms to the electrode, and a second TFT coupled to the electrode for discharging remnant charges from the electrode, wherein the second TFT is activated subsequent to the first TFT being deactivated.
