1. A display panel, wherein a demultiplexing circuit is disposed in the display panel, and the demultiplexing circuit comprises at least:
an N−1th stage demultiplexing subcircuit, wherein the N−1th stage demultiplexing subcircuit comprises at least M N−1th stage demultiplexing units configured to respond to N−1th stage control signals to time-sharingly output corresponding N−1th stage data signals; and
an Nth stage demultiplexing subcircuit, wherein the Nth stage demultiplexing subcircuit comprises at least M+1 Nth stage demultiplexing units, and an input terminal of the Nth stage demultiplexing subcircuit is connected to an output terminal of the N−1th stage demultiplexing subcircuit configured to respond to Nth stage control signals to time-sharingly output corresponding Nth stage data signals,
wherein an output terminal of one N−1th stage demultiplexing unit is connected to at least two input terminals of the Nth stage demultiplexing units, and M and N are both integers not less than 2.
