A multi optical-route Head Up Display (HUD), comprising: at least an image display unit, to generate at least two input images, and project them respectively to a plurality of relay lenses, which adjusts reflection angle of said input signals and then transmits them to a virtual image generation unit, said virtual image generation unit produces a plurality of virtual images, and transmits them to a plurality of transmission mirrors, which reflects said virtual images to form a large area virtual image. Based on technical contents mentioned above, size of optical elements of lens and mirrors can be reduced drastically, so that said multi optical-route HUD can be miniaturized, to achieve image display range of large area, thus the moving vehicle information frame required completely overlaps outside view, as such effectively solving defects of a conventional single optical-route image display device capable of only providing small area image display.

Multi optical-route head up display (HUD)

A Head Up Display (HUD), comprising: an image display unit, to generate input images; a virtual image generation unit, to receive said input images and generate at least a virtual image; a rotation mechanism, used to make said virtual image generation unit to change its projection angle, to project virtual images to a plurality of transmission mirrors; and a plurality of transmission mirrors, used to receive said virtual images and reflect them into a large area virtual image. Advantage of said HUD is that, size of lens and mirrors is reduced, so said HUD is miniaturized, while realizing large area image display, such that information frame of vehicle match that of outside view, hereby solving problems of single optical route display device of the prior art, that is only capable of displaying a small area image rather than a large area image.
