Control method of driving circuit, driving circuit and display device

The invention provides a control method of a driving circuit, the driving circuit and a display device. The control method of the driving circuit comprises the steps that when a display panel starts to be powered on, a first common voltage is output to a color film substrate through a power module, and a second common voltage is output to an array substrate through the power module; wherein the difference value between the second common voltage and the first common voltage is smaller than a preset voltage threshold value, so that the display panel does not emit light before entering a normal display stage; and when the display panel enters a normal display stage, outputting a third common voltage to the array substrate through the power supply module, and keeping outputting the first common voltage to the color film substrate, wherein the third common voltage is higher than the second common voltage and the first common voltage. The difference value between the first common voltage and the second common volta
