Abstract: A display apparatus is provided. The display apparatus includes a picture generation unit (110), a transflective member (120), and a curved mirror (130). The picture generation unit (110) is configured to generate imaging light including image information and project the imaging light to the transflective member (120), the transflective member (120) is configured to reflect the imaging light to the curved mirror (130), the curved mirror (130) is configured to reflect received imaging light to the transflective member (120), and the transflective member (120) is further configured to transmit the imaging light reflected by the curved mirror (130). Therefore, a light ray reflected by the curved mirror (130) may pass through the transflective member (120) and enter a human eye, and the human eye may capture a magnified virtual image via the light ray, thereby meeting a requirement for large-size viewing. Different from a real image display manner, the virtual image does not need to be borne by a specific screen, so that an effect of displaying a large-size image in a small space can be implemented.

Abstract: This application provides a display apparatus, an electronic device, and a vehicle. The display apparatus includes a picture generation unit, an imaging reflector, a detection unit, and a processing unit. The detection unit is deployed on a rear side of the imaging reflector. The picture generation unit is configured to generate an image, and send image light of the image to the imaging reflector. The imaging reflector is configured to reflect the image light to generate a virtual image of the image. The detection unit is configured to collect first signal light transmitted through the imaging reflector, where the first signal light is light reflected by an eye of a user viewing the virtual image. The processing unit is configured to determine a location of the eye of the user based on the first signal light collected by the detection unit, where a propagation direction of the image light reflected by the imaging reflector is parallel to a propagation direction of the first signal light. Therefore, the location of the eye of the user can be accurately detected when the user views the virtual image displayed by the display apparatus.
