Patent ID: 8405651

Claim:
A driving circuit, comprising: a power supply for providing a predetermined voltage; a plurality of conductive paths electrically connected to the power supply to receive the predetermined voltage; and a plurality of driving controllers, each of the driving controllers being electrically connected to one corresponding conductive path, the driving controllers comprising: a first driving controller having: a first internal circuit employing a first internal voltage to perform functions provided by the first driving controller; a resistance adjustment unit electrically connected between a special conductive path of the conductive paths and the first internal circuit; and at least one resistance adjustment circuit, one terminal thereof being electrically connected to gate terminal of at least one of the first transistors and gate terminal of at least one of the second transistors, and another terminal of the resistance adjustment circuit being electrically connected to the adjustment pad, such that the resistance adjustment circuit is configured for transmitting the predetermined potential to control on/off states of the at least one of the first transistors and the at least one of the second transistors electrically connected to the resistance adjustment circuit; and a second driving controller having a second internal circuit employing a second internal voltage to perform functions provided by the second driving controller; wherein a resistance value of the resistance adjustment unit is adjustable to make the first internal voltage same to the second internal voltage when the length of the conductive path corresponding to the first driving controller is different from the length of the conductive path corresponding to the second driving controller.
