Abstract
A shift register, gate drive circuit and display panel are provided. The shift register includes a latch unit, a NAND gate unit, a buffer unit and a switch unit. The latch unit, the NAND gate unit and the buffer unit are configured to produce a scanning driving signal and a scanning stopping signal. The latch unit is configured to control the switch unit to be turned on so as to output the scanning driving signal or the scanning stopping signal from the output terminal of the shift register, or control the switch unit to be turned off so as to enable the output terminal of the shift register to float.
