Abstract
A shift register and a shift register are provided. The shift register comprises the switch circuit, the latch circuit, and the inverter circuit. The shift register set, by alternately-serially connecting two types of shift registers, can receive two clock signals and an initial pulse signal to control the output waveform. The output of the present stage shift register can be used to control the turn-on time of the nest stage shift register. Further, by changing the circuit driving signal from the dynamic signal to the static signal, the circuit can operate only when the signal is '0' or '1' without being affected by the signal rising time and the falling time so that the circuit can operate in a more stable status.
