Abstract: Display panel, display device and detection compensation method of display panel are disclosed herein. In one embodiment, a display panel includes: display pixels arranged in M rows and N columns and provided in a display area, where both M and N are both positive integers; first power supply lines provided in the display area; and an integrated circuit, a switch circuit and a voltage stabilization transistor provided in a border area. One row of display pixels is electrically connected to one first power supply line. The first power supply lines are electrically connected to a first pin of the integrated circuit. A detection pin of the integrated circuit is electrically connected to the switch circuit. The voltage stabilization transistor includes: a control electrode electrically connected to the second pin, a first electrode electrically connected to the detection pin, and a second electrode electrically connected to one row of display pixels.
