Abstract
Embodiments of the application provide a shift register comprising a shift signal generating circuit and at least two time-sharing controlling circuits. The shift signal generating circuit may be configured to generate a shift signal. Each of the time-sharing controlling circuits comprises a first driving sub-circuit and a second driving sub-circuit, wherein the first driving sub-circuit is configured to enable the time-sharing controlling circuit to output the shift signal during the preset period, and the second driving sub-circuit is configured to enable the time-sharing controlling circuit to output an invalid signal during the non-preset period. During a driving cycle, the first driving sub-circuits in each of the at least two time-sharing controlling circuits are turned on sequentially, so that each of the at least two time-dividing controlling circuits outputs the shift signal sequentially.
