Near-to-eye display optical system and optical filter

Abstract

A near-to-eye display optical system includes a display assembly, an optical filter, a first optical assembly, and a second optical assembly. The display assembly is configured to emit light rays having image information. The optical filter is configured to transmit the light rays whose emergent angles meet a preset transmission condition and shield the light rays whose emergent angles do not meet the preset transmission condition. The first optical assembly is configured to receive and reflect the light rays transmitted through the optical filter, wherein the optical filter is disposed between the display assembly and the first optical assembly. The second optical assembly is configured to receive the light rays reflected by the first optical assembly and reflect the light rays to the first optical assembly. The present application further provides an optical filter and a near-to-eye display device.
