Abstract

A driving circuit for a display panel, a display device, and a driving method are provided. The driving circuit includes a common voltage feedback line and N common voltage detection units. The N common voltage detection units are electrically connected to N common voltage collection points of a common electrode of the display panel in one-to-one correspondence. Each common voltage detection unit includes a switch module and a logic circuit. The switch module has a first connection end electrically connected to a common voltage collection point corresponding to the common voltage detection unit and a second connection end is electrically connected to the common voltage feedback line. N logic circuits sequentially output control signals to corresponding switch modules, and control N switch modules to sequentially turn on, to make the N common voltage collection points sequentially output N common voltages through the turned-on switch modules and common voltage feedback line.
