Demultiplexer and method of controlling the same, and display device

A demultiplexer, comprising:

• a voltage boost circuit, wherein the voltage boost circuit is coupled to N second-stage selection signal input terminals and N first-stage selection signal input terminals, the N second-stage selection signal input terminals are in one-to-one correspondence with the N first-stage selection signal input terminals, and the voltage boost circuit is configured to successively boost voltages input via the N second-stage selection signal input terminals and output boosted voltages to corresponding first-stage selection signal input terminals, wherein N is greater than or equal to 2, and N is a positive integer;
• and
• at least one data selection output circuit, wherein each data selection output circuit is coupled to a data input terminal, N data output terminals and the N first-stage selection signal input terminals, and the data selection output circuit is configured to successively output data signals from the data input terminal to the N data output terminals under control of the N first-stage selection signal input terminals.
