Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A non-contact light emitting display for a vehicle is disclosed as having at least: a light emitting unit, a first induction coil to supply electric power for the light emitting unit; the first induction coil generates electric power by non-contact induction with an inductor of the vehicle for executing one way or two way signal transmission. Thereby, the non-contact light emitting display can save the provision of exposed electric conductors or conducting pins, it can obtain electric power from the vehicle to execute one way or two way signal transmission, or can be used on an aeronautic, a space or a sea vehicle for illumination with the effect of water proofness and dust proofness.
