Head-up display device for projecting information in field of view of driver in car, has transparent reflector partially reflecting light beam from curved light source to user, so as to perceive information in form of virtual image

摘要

The device (30) has a light source (31) intended to generate a light beam carrying information to be displayed. A transparent reflector (32) partially reflects the light beam from the light source to a user (35), so as to perceive the information in the form of a virtual image (34). An aspheric mirror is arranged to increase the size of the virtual image, where the light source is curved. The light source includes a laser projector emitting the light beam towards a convex face of a diffuser, so that light rays emitted by the projector are reflected by the diffuser.
