Abstract: An illumination device includes a housing, a first light-emitting element, a second light-emitting element, a substrate, and a reflector. The housing has a first light-outlet portion and a second light-outlet portion separated from each other. The first light-emitting element is disposed in the housing and suitable for emitting a first beam. The second light-emitting element is disposed in the housing and suitable for emitting a second beam emitted from the second light-outlet portion. The substrate is disposed in the housing and electrically connected to the first light-emitting element and the second light-emitting element. The reflector is disposed in the housing and located on a transmission path of the first beam. The reflector is suitable for reflecting the first beam to the first light-outlet portion.

Abstract: A screen illumination device includes a body, a first light source, and a second light source. The body includes a first housing and a second housing. The second housing is detachably connected to the first housing. The first light source is connected to the body and adapted to generate a first light beam. The second light source is connected to the body and adapted to generate a second light beam. The first housing is adapted to allow the first light beam to emit out along a first direction, the second housing is adapted to allow the second light beam to emit out along a second direction, and the second direction is different from the first direction.

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.
