Head-mounted display apparatus and optical display system

A head-mounted display apparatus, comprising:

• a display assembly, adapted to output light of an image;
• a lens assembly, positioned in front of the display assembly and adapted to enlarge the image and produce a first aberration of a first direction;
• and
• a planar optical assembly, positioned between the display assembly and the lens assembly,
• wherein the planar optical assembly is adapted to produce a second aberration of a second direction opposite to the first direction to correct the first aberration,
• wherein the display assembly comprises:
• a display component;
• and a first circular polarizer, adapted to convert light from the display component into circular polarized light,
• wherein the planar optical assembly includes:
• polarization-dependent planar optics adapted to receive one or more of a right-handed or left-handed circular polarized light and convert at least a portion thereof into oppositely circular polarized light and leak any remaining light;
• and a polarization blocker, adapted to block the leaked light, and
• wherein the polarization blocker is a second circular polarizer, and the second circular polarizer blocks the leaked light with original handedness and passes the opposite handedness light.
