1. A level conversion circuit, comprising:
at least two level conversion sub-circuits; and
at least one first switch sub-circuit; wherein
each of the at least one first switch sub-circuit is connected to at least one of a plurality of input control terminals and at least one of the level conversion sub-circuits; and each of the at least one first switch sub-circuit is configured to provide an input control signal provided by each connected input control terminal to the connected level conversion sub-circuit in response to a first switch control signal; and
each of the level conversion sub-circuits is further connected to at least one first power supply terminal, at least one second power supply terminal and at least one of a plurality of output signal terminals, each of the output signal terminals being further connected to a gate driving circuit; and each of the level conversion sub-circuits is configured to transmit, in response to the received input control signal, a first power supply signal provided by one first power supply terminal or a second power supply signal provided by one second power supply terminal to each connected output signal terminal;
wherein the first power supply signals provided by the first power supply terminals connected to the at least two level conversion sub-circuits are at different levels, and the second power supply signals provided by the second power supply terminals connected to the at least two level conversion sub-circuits are at different levels.
