1. An optical display system, comprising:
a display panel, adapted to generate a first image light and a second image light in a time division multiplexed manner, wherein the first image light and the second image light are generated by the same display panel,
a polarization modulator, arranged optically downstream of the display panel, and adapted to modulate the first image light and the second image light into a first polarization state and a second polarization state in a time division multiplexed manner corresponding to that of the display panel,
a resolution enhancement optic unit, arranged optically downstream of the polarization modulator, and adapted to enhance a resolution of the first image light with respect to the second image light;
a magnifying optic unit, arranged optically downstream of the resolution enhancement optic unit, and adapted to magnify the first and second image lights from the resolution enhancement optic unit; and
a polarized deflector, placed before the magnifying optic unit,
wherein the resolution enhancement optic unit includes a partial reflector, a first optic unit and a polarized reflector,
wherein the partial reflector is adapted to transmit the first image light and the second image light without changing their polarization states and reverse the polarization states thereof when reflecting them,
wherein the first optic unit includes at least one refractive lens to provide needed resolution enhancement for the first image light,
wherein the polarized reflector is adapted to reflect an image light of a first polarization with keeping its polarization state and transmit an image light of a second polarization without changing its polarization state,
wherein the polarized deflector comprises two Pancharatnam-Berry deflectors arranged on both sides of the polarized reflector, and
wherein the polarized deflector is electronically controlled and adapted to deflect an image with designed angle, thereby shifting a position of a foveated area formed by the first image light to match a position of a viewer's eye.
