Driving circuit

摘要

A driving circuit includes several first electrostatic current limiting resistors and several digital to analog converter (DAC) units. First ends of these first electrostatic current limiting resistors common coupled to a global path to receive a reference voltage. These DAC units respectively coupled to second ends of the first electrostatic current limiting resistors one-on-one to receive the reference voltage through the first electrostatic current limiting resistors.
