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.
