  • Method and circuit for compensating pixel drift in active matrix displays
    Patent number: 8847942
    Abstract: An apparatus includes a circuit branch electrically connected to a voltage rail and including a light emitting device connected in series with a drain of a dual gate transistor, a switching transistor configured to apply a data voltage to a first gate of the dual gate transistor in response to a scan signal, a capacitor connected between the first gate of the dual gate transistor and the drain of the dual gate transistor, and a conductor for supplying a control voltage to a second gate of the dual gate transistor. A method of operating the circuit is also described.
    Type: Grant
