  • Patent number: 10217391
    Abstract: Disclosed is a shift register unit, a gate driving circuit and a driving method, as well as a display apparatus. The shift register unit has a working cycle including an input phase, an output phase, a reset phase and a maintaining phase. In the reset phase, a clock signal is transmitted to an output terminal to pull a voltage of the output terminal down to a reference voltage, and the pulled-down voltage of the output terminal is subsequently changed from the reference voltage to a gate-off voltage. In the maintaining phase, the voltage of the output terminal is maintained at the gate-off voltage. The reference voltage is smaller than the gate-off voltage.

  • Publication number: 20180061340
    Abstract: Embodiments of the disclosure disclose a gate driving circuit, a driving method, and a display device. In the gate driving circuit, the input module transmits the input signal of the input signal terminal to the first node. The reset module resets the first node and the output terminal of the gate driving circuit. The pull-down module pulls down the signal of the first node and the signal of the output terminal of the gate driving circuit to low level signals. The pull-down control module generates a voltage signal of the second node based on the signal of the noise-canceling signal terminal, and controls the pull-down module to pull down a high level noise signal at the first node to a low level signal using the voltage signal. The pull-up module pulls up the signal of the output terminal of the gate driving circuit to a high level signal.

  • Patent number: 9083994
    Abstract: A method and system for resynchronizing an embedded multimedia system using bytes consumed in an audio decoder. The bytes consumed provides a mechanism to compensate for bit error handling and correction in a system that does not require re-transmission. The audio decoder keeps track of the bytes consumed and periodically reports the bytes consumed. A host microprocessor indexes the actual bytes consumed since bit errors may have been handled or corrected to a predetermined byte count to determine whether resynchronization is necessary.
