description The invention discloses a method and a device for detecting a display. The method is characterized by comprising the steps of controlling an image signal generator to generate a chessboard image, and controlling the image signal generator to send the chessboard image to the to-be-detected display, so that the display displays the received chessboard image; controlling a camera to shoot the chessboard image displayed on the display, and obtaining the chessboard image shot by the camera; judging whether the number of angular points of the obtained chessboard image is H, H=(N+1)*(M+1); if yes, judging the display does not exist an apparent display defect; and if no, judging the display exists the apparent display defect; and correspondingly, the invention further discloses a device for detecting the display. By adopting the method and the device disclosed by the embodiment of the invention, as an automation standard is adopted for detecting, the accuracy is high, and whether the display exists the display defect
