摘要： A driving circuit includes a power supply, a plurality of conductive paths and a plurality of driving controller. The power supply is configured for providing a predetermined voltage. The conductive paths are connected to the power supply to receive the predetermined voltage. The driving controllers are connected to the conductive paths correspondingly. A first driving controller of the driving controllers has a first internal circuit configured for employing an internal voltage to perform functions provided by the first driving controller, and a resistance adjustment unit. The resistance adjustment unit is connected between a special conductive path and the first internal circuit. The second driving controller has a second internal circuit configured for employing a second internal voltage to perform functions provided by the second driving controller. A resistance value of the resistance adjustment unit is adjustable to make the first internal voltage same to the second internal voltage.
