Abstract
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.
