Abstract

The embodiments of the present invention provide a head-up display, a head-up display method and a vehicle-mounted display device. The head-up display includes: a digital light processing unit used for generating an imaging beam; a reflector unit used for reflecting the imaging beam to a reflective surface cooperating with the head-up display to form an image; and an adjusting unit used for adjusting a direction of the reflector unit, thereby providing a desired depth to the image. In the embodiments of the invention, by presenting an image with a desired depth, the displayed information can be fused together with the environment. In this way, information can be presented in the best mode, visual fatigue of the driver can also be effectively avoided, thereby avoiding danger.
