Abstract
The present disclosure provides an optical polarizing device and a manufacturing method therefor, and a near-eye display apparatus. The optical polarizing device includes: a reflective polarizing film, a linear polarizing coating located on one side of the reflective polarizing film, and a phase retardation coating located on the other side of the reflective polarizing film. A distance between at least one of the linear polarizing coating and the phase retardation coating and a surface of the reflective polarizing film is less than 0.5 micrometers.

An optical polarizing device, comprising:
- a reflective polarizing film;
- a linear polarizing coating located on one side of the reflective polarizing film;
- and
- a phase retardation coating located on the other side of the reflective polarizing film,
- wherein a distance between at least one of the linear polarizing coating and the phase retardation coating and a surface of the reflective polarizing film is less than 0.5 micrometers.
A method for fabricating an optical polarizing device, comprising:
- preparing a reflective polarizing film;
- forming a linear polarizing coating on a surface of a first side of the reflective polarizing film;
- and
- forming a phase retardation coating on a surface of a second side of the reflective polarizing film opposite to the first side,
- wherein a distance between at least one of the linear polarizing coating and the phase retardation coating and a surface of the reflective polarizing film is less than 0.5 micrometers.
A near-eye display apparatus, comprising:
- a display device, and an optical component arranged on a light-exiting side of the display device, wherein the optical component comprises at least one lens and an optical polarizing device formed on a surface of the at least one lens, the optical polarizing device comprises:
- a reflective polarizing film;
- a linear polarizing coating located on one side of the reflective polarizing film;
- and
- a phase retardation coating located on the other side of the reflective polarizing film,
- wherein a distance between at least one of the linear polarizing coating and the phase retardation coating and a surface of the reflective polarizing film is less than 0.5 micrometers.
