  • Patent number: 10600492
    Abstract: The present invention discloses a high stability shift register with adjustable pulse width to be achieved by a circuit structure through purely N-type transistors or purely P-type transistors. The structure comprises eight thin film transistors and a capacitor, and uses the 8T1C structure as a repeating unit. The invention can obtain an output signal from an input signal, two DC signals and two AC signals. The AC signal is a two line-time frequency pulse wherein the pulse width is smaller or equal to the line-time. The output signal will shift a line-time on the time axis with the input signal, and as an input signal to the next shift register in sequence. Compared with the conventional technique, the invention reduces the amount of the components to obtain a high stability and adjustable pulse width shift register.
