Abstract: An optical display system and an electronic device are disclosed. The optical display system comprises: a controllable optical image-generating display apparatus, generating circularly polarized image output; a beam scanning unit, adjusting a direction of the circularly polarized image output; an exit pupil steering apparatus, including diffractive liquid crystal lenses, each of which focuses the circularly polarized image output of one circular polarization state to a distinct focus point and let light with the other circular polarization state pass directly through; and an eye-tracking apparatus, detecting position information of a viewer's eye pupil and providing the position information to the beam scanning unit. The beam scanning unit adjusts the direction of the circularly polarized image output according to the position information, so that the circularly polarized image output is diffracted by one of the diffractive liquid crystal lenses.
