Abstract: A projection device configured to provide multiple projection modes is provided. The projection device includes a housing module and a projection module. The housing module includes a display screen and multiple protective walls. The display screen includes a display curved surface. The projection module includes an optomechanical assembly and a light guide assembly. In a first projection mode, the optomechanical assembly projects an image light beam to the light guide assembly along a first axis. The light guide assembly projects the image light beam to the display curved surface along a second axis, where the first axis and the second axis are not parallel to each other. In a second projection mode, the light guide assembly is moved out of a transmission path of the image light beam, so that the image light beam is directly projected out of the projection device.

Abstract: Medical imaging equipment and a medical imaging method are provided. The medical imaging equipment includes medical equipment, a controller, and a head-mounted display. The medical equipment is configured to investigate a body portion and output a first image signal corresponding to the body portion. The first image signal has a first resolution. The controller is coupled to the medical equipment to receive the first image signal and convert the first resolution of the first image signal to a second image signal having a second resolution. The head-mounted display is coupled to the controller to display a display image of the second image signal. The head-mounted display has a direction line. When the head-mounted display faces the body portion, the display image and the body portion are located along to the direction line.

Abstract: A display control method, a display control system, and a wearable device are provided. The display control system includes a display device and a wearable device. The wearable device includes a detector and a microcontroller. The display control method is suitable for the display control system. The method includes: establishing a connection with the display device by the wearable device; in response to the wearable device detecting a display activation operation, enabling a display function of the display device through the connection by the wearable device; and in response to the wearable device detecting a communication activation operation, activating a communication mode between the wearable device and the display device by the wearable device. By using the display control system and method provided by the invention, the user can remotely operate the display device under relatively unrestricted conditions, and that operation is conveniently performed.
