Abstract
The present application discloses a display panel, a pixel circuit and a method for driving the pixel circuit. The pixel circuit includes a drive chip, a plurality of pixel circuit units and a plurality of detection circuit units, the pixel circuit unit including a first switch tube and an electroluminescent element. A first path end of the first switch tube is connected to an anode of the electroluminescent element. A control end of the first switch tube is connected to a scan signal end. The first path end of the second switch tube is connected to the anode of the electroluminescent elements via the pixel circuit unit.
