1. A detection device of a display panel, comprising:
an image receiver configured to receive a detection image of a display panel to be detected; and
a detector configured to input the detection image of the display panel to be detected into a detection model and generate a detection result by the detection model, the detection model being pre-constructed and configured to detect the display panel;
wherein the detection model comprises:
a defect classification identification sub-model configured to identify a classification of a defect of the display panel to be detected;
a defect position identification sub-model configured to mark a position of the defect of the display panel to be detected;
wherein the defect classification identification sub-model comprises a plurality of base models and a secondary model;
the plurality of base models are configured to determine an initial classification of the defect of the display panel to be detected; and
the secondary model is configured to determine a final classification of the defect of the display panel to be detected according to input data obtained by integrating output data of the plurality of base models.
