  • Dual gate pixel reset for a display device
    Patent number: 9459445
    Abstract: Electrowetting elements of a display device include a support plate, a bottom electrode, electrowetting oil and an electrolyte on the bottom electrode. The electrowetting oil is immiscible with the electrolyte, a top electrode is in electrical contact with the electrolyte, and the bottom electrode, the top electrode and the electrolyte form a portion of a circuit. The electrowetting elements each further include a first thin film transistor (TFT) that is switched on to select each of the electrowetting elements using active matrix addressing, and a second TFT that is switched on to provide a reset pulse to the portion of the circuit. The reset pulse can be used to reduce or eliminate backflow of the electrowetting oil.
