Test structure of display screen

The utility model relates to a test structure of a display screen. The test structure comprises a main body shell, a support structure and a contact mechanism, the sensor is arranged in the main body shell, one end of the flat cable is connected with the sensor, the other end of the flat cable penetrates through the mounting groove and the through hole to be fixedly connected with the detection block, the flat cable is further pressed by the pressing plate, and the bolt sequentially penetrates through the first threaded hole and the second threaded hole, so that the flat cable can be quickly fixed through the structure; the problem that a flat cable and a first detection block are disconnected due to frequent telescopic actions of a telescopic rod is effectively prevented, firstly, the display screen is placed in a placement groove, a driving structure is further driven to work, the driving structure drives the telescopic rod to contract towards the interior of a main body shell, and the detection block abuts
