Shift register unit, display panel and display apparatus

A shift register unit, comprising:

• a latch circuit, configured to
• process a clock signal received by a first clock signal end of the shift register unit and a low level signal by a NOR operation to obtain a signal, and output the obtained signal, during a time period where a selection signal is of a high level, wherein the clock signal received by the first clock signal end is of a low level when the selection signal is of a high level;
• process the signal outputted by the latch circuit when the selection signal is of a high level by a NOT operation, then process the resultant signal with a feedback signal by a NOR operation to obtain a signal, and output the obtained signal, during a first time period where the selection signal is of a low level;
• and
• output a low level signal, during a time period where the selection signal is of a low level other than the first time period where the selection signal is of a first low level;
• and
• a transmission circuit, configured to
• output a signal related to the clock signal received by the first clock signal end when the signal outputted by the latch circuit is of a high level;
• and
• output a corresponding signal when the signal outputted by the latch circuit is of a low level;
• wherein, the feedback signal is able to make the signal outputted by the latch circuit during the time period where the selection signal is of a high level and the signal outputted by the latch circuit during the first time period where the selection signal is of a low level be the same;
• the feedback signal is converted from being of a low level to being of a high level, at an end time point of the first time period where the selection signal is of a low level;
• and
• the first time period where the selection signal is of a low level is a time period from a time point when the selection signal is converted from being of a low level to being of a high level to a time point when a signal outputted by a next stage shift register unit with respect to the shift register unit jumps from being of a low level to being of a high level.
