A driving circuit applied to a LCD apparatus includes N driver chips, a signal source, a WOA wire, a COF wire. Each driver chip is COF-packaged and correspondingly coupled to L output channels. N and L are positive integers and N≥2. The signal source is coupled to L output channels of the first driver chip. One terminal of WOA wire is coupled to L output channels of the second driver chip. One terminal of the COF wire is coupled between the signal source and a first output channel of the first driver chip and another terminal of the COF wire is coupled to another terminal of WOA wire. The resistance of COF wire is far smaller than a first internal resistance between the first output channel and L-th output channel of first driver chip and the resistance of WOA wire is substantially equal to first internal resistance.
