Near eye display prism optic assembly

A method for near-eye display based on a prism optic assembly, comprising:

• emitting light rays from a movable flat panel display surface based on a linear drive mechanism, the emitted light rays being referenced by an axis representing an axial principal ray;
• transmitting said emitted light rays through a first optical surface of an optical member, said first optical surface being a flat transmitting surface;
• first reflecting said transmitted tight rays by a first reflecting surface of said optical member;
• second reflecting said first reflected light rays by a second optical reflecting surface of said optical member;
• and
• second transmitting said second reflected light rays through a second transmitting surface for adjustable focusing towards an observer's eye, wherein said second transmitting surface and said first reflecting surface are provided by a common optical surface of said optical member, wherein a corrector lens grouping is movably configured along said axis to allow adjustment to diopter focus.

An optical assembly comprising:

• a color micro-display image source configured with linear drive mechanisms;
• a plastic prism with one flat surface to receive said color micro-display image;
• and
• a collimating optic lens to provide the capability of imaging said color micro-display to a viewer's eye, wherein said collimating optic lens and said flat prism surface are optically configured for aberration-free diopter adjustment of at least one of said color micro-display image source and said collimating optic lens towards reduced, nearly-symmetric distortion in said viewed image, wherein said collimating optic lens is movably disposed to allow a minor adjustment to diopter focus.
