Abstract:
1. A shift register unit comprising at least a pull-up drive module, a first pull-down drive module, a second pull-down drive module and an output module: the pull-up drive module being used for outputting a received high level signal to the output module when a received scan trigger signal is of high level; the output module being used for receiving and storing the signal outputted by the pull-up drive module, and outputting a received clock blocking signal through an output end of the shift register unit when the stored signal is of high level; when the scan trigger signal is of high level, the clock blocking signal being of low level; the first pull-down drive module being used for connecting the output end of the shift register unit with a low level signal end when a received clock signal is of high level, or when the received clock signal is of low level, and the output end of the shift register unit is of low level; and disconnecting the output end of the shift register unit from the low level signal end when the output end of the shift register unit is of high level; the clock signal being contrary to the clock blocking signal; the second pull-down drive module being used for outputting a low level signal to the output module when a received enable signal is of high level so as to set the signal stored by the output module to be of low level; when displaying a frame of images, the enable signal being of high level in periods of time other than the period of time when the scan trigger signal is of high level and the period of time when the output end of the shift register unit is of high level.
