    Abstract: A method for driving an electro-optic display having a front electrode and a rear electrode, a display medium position between the front and rear electrode, and a transistor coupled to the rear electrode, the driving method may include applying a first voltage to the front electrode and a second voltage to the rear electrode, applying a third voltage to the front and rear electrodes to create a substantially zero volt potential across the display medium, wherein the third voltage is of a magnitude insufficient to create a leakage current of sufficient magnitude in the transistor to cause an optical effect on the display, and applying a fourth voltage to the front electrode and a fifth voltage to the rear electrode.

    Abstract: The invention provides methods and related apparatuses for driving an electro-optic display having an electrophoretic display medium electrically coupled between a common electrode and a display pixel associated with a display pixel electrode and an n-type transistor electrically coupled to a display controller circuit capable of applying waveforms comprising frames to the display pixel by applying voltages to the common electrode and the display pixel electrode via the n-type transistor. The method includes applying one or more waveforms to the display pixel to drive the electrophoretic display medium in proximity to the display pixel to a first optical state, and discharging a remnant voltage from the electrophoretic display medium utilizing a leakage conduction effect of the n-type transistor. The method can also include maintaining the display pixel in the first optical state for a hold period comprising one or more frames, and placing the display pixel in a floating state.

    Abstract: An electro-optic display including a first subpixel electrode and a second subpixel electrode associated with a display pixel, and an electrophoretic display medium disposed between a common electrode and the first and second subpixel electrodes. The electro-optic display also includes a display controller circuit in electrical communication with the common electrode and a first transistor associated with the display pixel. The display controller circuit is capable of applying waveforms to the display pixel by applying one or more time-dependent voltages between the common electrode and the first subpixel electrode via the first transistor, where the one or more time-dependent voltages are applied to the first subpixel electrode. The electro-optic display also includes a second transistor in electrical communication with the first subpixel electrode and the second subpixel electrode. A first enable signal activates the second transistor to place the first subpixel electrode and the second subpixel electrode into electrical communication.
