Abstract
An electro-optic display having a plurality of display pixels, each of the plurality of display pixels comprising: a pixel electrode for driving the display pixel; a thin film transistor (TFT) coupled to the pixel electrode for transmitting waveforms to the pixel electrode; a resistor coupled to the pixel electrode for discharging remnant charges from the display subsequent to the TFT being de-activated; and a storage capacitor coupled to the pixel electrode and placed in parallel with the resistor. A time constant of a circuit comprising the pixel electrode, the resistor, and the storage capacitor is larger than a driving frame time of the electro-optic display.
