Abstract: A display device includes a display and a detection module. The display includes a display surface and a casing, and the casing exposes the display surface. The detection module includes a pivoting component and a sensing component. The pivoting component is disposed on the casing and includes a bearing. The sensing component includes a sensor and a sensing surface. The sensing component is disposed on the bearing and is configured to rotate about an axis of the bearing so that the sensing surface faces the display surface. The sensor is configured to provide a position sensing signal for determining whether the sensing component has rotated to a detection position. A display calibration method is also provided.
