1. An electronic device, comprising:
a circuit board;
a first level shift integrated circuit disposed on the circuit board; and
a second level shift integrated circuit disposed on the circuit board;
wherein each of the first level shift integrated circuit and the second level shift integrated circuit includes a plurality of clock signal output pins and a common pin, and each clock signal output pin outputs a clock signal;
wherein the common pin of the first level shift integrated circuit is electrically connected to the common pin of the second level shift integrated circuit through a conductive wire on the circuit board;
wherein each clock signal includes a step-up phase and a step-down phase, and the step-down phase of a clock signal outputted from a clock signal output pin of the first level shift integrated circuit overlaps the step-up phase of a clock signal outputted from a clock signal output pin of the second level shift integrated circuit for realizing charge sharing between the first level shift integrated circuit and the second level shift integrated circuit.
