  • Shift register units, display panels utilizing the same, and methods for improving current leakage thereof
    Patent number: 7916114
    Abstract: A shift register comprising at least one shift register unit. The shift register unit comprises an input unit, at least one first TFT, and at least one second TFT. The input unit receives an input signal from the input terminal and outputs a switching control signal in accordance with a first clock signal. The gate of the first TFT is for receiving the switching control signal, the drain of the first TFT is for receiving a second clock signal, and the source of the first TFT is coupled to the output terminal. The gate and drain of the second TFT are coupled to the output terminal, and the source of the second TFT is coupled to the input unit.

  • Voltage level shifter and sequential pulse generator
    Patent number: 7088165
    Abstract: A voltage level shifter. The voltage level shifter comprises a shifter unit and a controller. The shifter unit outputs a third signal according to a first signal and a second signal. When the first signal remains at a first level a current path is formed in the shifter unit. The controller is coupled to the shifter unit and stops the current path when the first signal remains at the first level.
