Abstract: The disclosure discloses a detection device and a detection method for detecting the curvature of a display panel, including a detection platform which carries and transfers the display panel; a distance sensor installed on the detection platform and detecting a first height value H1 of the height between the end of the display panel and the distance sensor; and a controller which electrically connects the distance sensor, the controller includes a processor and a memory, the memory stores an executable instruction, the processor executes the executable instruction, the executable instruction includes sending the first height value H1 to the controller, the controller compares the first height value H1 with a reference height value H2, and issues a warning if the difference value ?H between the first height value H1 and the reference height value H2 is greater than a preset threshold value H.
