A vehicular head-up display system provides a driver with two virtual images in different image distances, wherein each of the virtual images utilizes all pixels of a single image source. Linearly polarized light beams, which are emanated from the image source, pass through a dynamic polarization converter, whereby to form two image light beams with orthogonal polarization states that are switched fast for time-multiplexing. The two image light beams are selected by a polarization selection component for transmission and reflection respectively. The reflected image light beam is handled by an optical relay component to form an intermediate image. A curved mirror reflects the two image light beams to a virtual image reflecting surface to form two virtual images in different virtual image distances in respect to eyes of a driver in front of the virtual image reflecting surface.
