Abstract
A head-up display is used for providing traffic information for a driver. The head-up display includes a projector, a reflector and a spherical mirror; the spherical mirror is a transparent concave mirror; a distance from the reflector to the spherical mirror is less than 1 * focal length of the spherical mirror; the projector is used to project an image of the traffic information to the reflector; after receiving the image of the traffic information, the reflector reflects the image of the traffic information to the spherical mirror; the spherical mirror is used for imaging the image of the traffic information reflected by the reflector. Because the spherical mirror is the transparent concave mirror, view of the driver cannot be affected when the driver looks over the traffic information through the spherical mirror; and the distance from the reflector to the spherical mirror is less than 1 * focal length of the spherical mirror of the spherical mirror, so that miniaturization of the head-up display can be achieved.
