1. A driving circuit, comprising:
a segment display, comprising a plurality of light-emitting units;
a controller, configured to generate a control instruction for the segment display according to a configuration signal;
a digital driver, connected to the controller, and configured to generate a pulse driving signal according to the control instruction generated by the controller; and
an amplification circuit, with one end being connected to the digital driver and the other end being connected to the plurality of light-emitting units of the segment display, and configured to amplify the pulse driving signal, wherein the amplified pulse driving signal is used for driving the light-emitting units of the segment display to emit light,
wherein there are a plurality of segment displays, and each segment display comprises a plurality of light-emitting units,
wherein driving circuit further comprises:
a gating circuit, comprising a plurality of gating switches, wherein one end of each gating switch is connected to the digital driver, and the other end is connected to one segment display,

wherein the control instruction further comprises a gating instruction, and the digital driver is further configured to generate a gating pulse signal according to the gating instruction, to drive a target gating switch of a selected target segment display to be turned on, and
wherein the gating switch comprises:
a first triode and a second triode, wherein the first triode is connected to the digital driver, and the second triode is connected to one segment display; and
a first noise reduction circuit, connected between the first triode and the second triode, and configured to reduce a noise signal of the gating switch.
