Abstract
A shift register includes a shift module configured for causing the cascade signal output end to output a cascade signal in response to a signal of the input signal end; an reverse output module configured for causing the reverse signal output end to output a signal reverse to the cascade signal output end in response to a signal of the cascade signal output end; a latch module configured for causing an output end of the latch module to output a control signal of the masking signal end in response to signals of the cascade signal output end and the reverse signal output end of a previous level; and a selection output module configured for providing a signal of the first power supply end or the second power supply end to the driving signal output end in response to a signal of the output end of the latch module.
