Abstract
A display system and a vehicular head-up display system using the same is disclosed. The display system includes an image generating device, a polarization reflection film, a light-transmitting substrate, a curved wave plate, a curved reflector and a transparent substrate. The image generating device emits polarized light. The curved wave plate adheres to the reflective curved surface of the curved reflector through an optical adhesive. The curved wave plate and the reflective surface have the same curvatures. The reflective curved surface faces towards the polarization reflection film. When the curved reflector reflects the polarized light sequentially passing through the polarization reflection film and the curved wave plate to the polarization reflection film through the curved wave plate, the curved wave plate converts the polarization direction of the polarized light. Finally, the polarization reflection film reflects the polarized light to the transparent substrate to generate a virtual image.
