The present disclosure provides a display panel, a driving method and a display device. The display panel includes first data lines and first gate lines in an auxiliary display area, a first scanning unit, M second scanning units, M switch unit groups corresponding to the M second scanning units, M second data lines corresponding to the M switch unit groups, where M is an integer greater than 1. Each second scanning unit has output terminals and a control terminal connected to a main driving chip. Each switch unit group includes a plurality of switch units having a plurality of control terminals connected to the output terminals of the second scanning unit, a plurality of first terminals respectively connected to the first data lines, and second terminals. Each second data lines is connected to the main driving chip and the second terminals of the switch units.
