Abstract
An imaging module includes a display element, a prism and an image displacement device. The display element includes an active display surface. The prism includes an optical surface. The image displacement device is disposed between the display element and the prism. The image displacement device includes an optical element, a carrier, a base and at least one actuator. The optical element is disposed on the carrier. The at least one actuator drives the optical element on the carrier to swing relative to the base.
Claims26
An imaging module, comprising:
- a display element, comprising an active display surface;
- a prism, comprising an optical surface;
- and
- an image displacement device, disposed between the display element and the prism, wherein the image displacement device comprises:
