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: An electronic device includes a transparent first display panel, a second display panel and a processor electrically connected to the two panels. The first display panel is movable with respect to the second display panel. The processor is configured to switch between a plurality of display modes based on relative positioning of the two panels and to provide video signals to the two panels based on a current display mode. When the first display panel is parallel to the second display panel and faces a display area of the second display panel, the processor executes a stereoscopic display mode. When an angle between the two panels is between 0 and 180 degrees, exclusive, the processor executes an augmented reality display mode. When the display areas of the two panels are oriented away from each other, the processor executes a dual display mode.
