Organic electroluminescent display panel, display device, and detection method

An organic electroluminescent display panel, comprising a display area and a non-display area surrounding the display area, the display area comprises a hole area;

• wherein,
• the non-display area comprises two light-emitting control circuits, and the two light-emitting control circuits are respectively located on two sides of the display area;
• the display area comprises a plurality of light-emitting control lines, and the light-emitting control lines comprise a first light-emitting control line electrically connected to the two light-emitting control circuits;
• and
• the first light-emitting control line comprises:
• a surrounding portion surrounding the hole area, and a connecting portion respectively electrically connecting both ends of the surrounding portion to the two light-emitting control circuits, wherein the connecting portion is electrically connected one light-emitting control circuit through by a control component, and the control component is configured to disconnect the light-emitting control circuit from the connecting portion when defect detection is performed, to determine a cracking state of the hole area according to a light-emitting state of pixels driven by the connecting portion between the control component and the hole area.
