6. A driving method of a display device, wherein the display device comprises a first electrode serving as a touch electrode, a second electrode, and a display medium layer, and the display medium layer is configured between the first electrode and the second electrode, the driving method comprising:
during a touch sensing period, providing a touch driving signal to the first electrode, and performing touch sensing by the first electrode based on the touch driving signal; and
configuring a first average voltage value of the first electrode to be equal to a second average voltage value of the second electrode,
wherein the display device further comprises an active element array substrate, and the active element array substrate comprises a scan line, a data line, a transistor, a pixel electrode, and the second electrode,
wherein the transistor comprises a gate terminal and a source terminal, the gate terminal is electrically connected to the corresponding scan line, and the source terminal is electrically connected to the corresponding data line,
wherein the pixel electrode is electrically connected to the transistor, and the second electrode and the pixel electrode form a storage capacitor,
wherein the display medium layer is configured between the first electrode and the active element array substrate.
