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.

Abstract: A virtual reality display system of reduced size and depth but with a point of focus electronically changeable to suit different human eyes includes a display device and a focusing structure. The display device emits light for images, the focusing structure on the light path includes a first electrode layer, a second electrode layer, and a first liquid crystal layer between the first electrode layer and the second electrode layer, these two electrode layers receiving different voltages. The first liquid crystal layer is configured to converge the image light as necessary for the viewer and enlarge images as desired by the viewer. The image light after being focused displays a virtual reality image.
