Shift register

Abstract

The invention discloses a shift register, comprising a preceding-stage signal reception unit, a backward-stage signal reception unit, a control unit, and a voltage stabilization switch. The shift register controls signals to be output by virtue of continuous and stable voltage through the cooperative operation of circuits.

Description

technical field [0001] The present invention relates to a shift register, and in particular to a shift register (SHIFT REGISTER) with a stable output control voltage. Background technique [0002] The shift register is a widely used electronic component, and it can be seen in many electronic products. To put it simply, multiple shift register stages are generally connected together to form a shift register group, and an electronic signal is transmitted from the shift register of the previous stage to the shift register of the next stage. in the bit register. In this way, by shifting the delay time of signal transmission in the shift register group, an electronic signal can be made to perform correct functions at different times and at different positions. [0003] Please refer to Figure 1A and Figure 1B ,in Figure 1A is a circuit diagram of a common shift register, and Figure 1B It is a signal waveform diagram of each corresponding node of the shift register. Such a...

However, since the on / off operation of the transistor requires a transition time, when the P-type transistors P1 and P2 are turned on / off, the potential on the output signal N is likely to be unstable.
