摘要： The present invention provides a driving method and a driving circuit of a display panel and a display device. The display panel comprises: gate lines and data lines and pixel units, the data lines comprises: first data lines and second data lines, and a first predetermined number of first data line(s) and a second predetermined number of second data line(s) are alternately arranged. The driving method comprises a step of: scanning the gate lines in turn, wherein when scanning one gate line, a data voltage signal is applied to the first data lines or the second data lines. The driving method provided by the present invention can allow the pixel units on the OLED panel to display alternately, and since the area of each pixel unit is relatively small with respect to the area of the whole OLED panel, such alternate display manner has a relatively small effect on the image display quality of the OLED panel. Meanwhile, compared to the driving method in the prior art, the driving method provided by the present invention allows lower power consumption of the OLED panel when display at the same brightness is achieved.
