Abstract
A display device including a display module and a calibration module is provided. The display module has a light exit surface. The calibration module includes a detecting component and a connecting component. The connecting component is configured to connect the detecting component and display module. The connecting component includes a connecting rod, a guiding rail and a rotating unit. The detecting component is disposed on one side of the connecting rod. The sliding rail has a guiding hole, and the connecting rod passes through the guiding hole. The rotating unit is connected to the other end of the connecting rod. When the rotating unit rotates, the connecting rod moves along the guiding hole between a first end and a second end of the guiding hole, so that the detecting component moves between a detection position and a stowed position. The detection position is located on the light exit surface.
