Abstract: A backlight module, a holographic display device and a holographic display method thereof are provided. The backlight module includes a semi-transparent layer and a reflective layer which are disposed opposite to each other, a light source, and a deflectable optical device. The light source is configured to emit a light beam, the deflectable optical device is configured to deflect a propagation direction of the light beam emitted from the light source and make the reflected light beam enter between the semi-transparent layer and the reflective layer in an angle, and is deflectable to change the angle.

Abstract: The disclosure discloses a display apparatus and an on-vehicle head-up display system. The display apparatus comprises two imaging devices apart by a set distance, an optical splitter, and a reflector; wherein the two imaging devices are configured to display a left eye image and a right eye image respectively; the optical splitter is configured to receive and transmit emergent light of the two imaging devices to the reflector and to reflect reflected light of the reflector to set positions, wherein the set positions are symmetric with exit pupil positions of the two imaging devices with respect to a light splitting surface of the optical splitter; and the reflector is configured to reflect incident light back along its incident path.
