Abstract

The invention discloses a near-to-eye display system and a head-mounted display device. The near-to-eye display system comprises a display, an imaging lens group, a light splitting part, a phase retarder and a polarization reflection film, the display is used for emitting light rays, the display is of a curved surface structure, and the bending direction of the display faces the propagation direction of the light rays; the imaging lens group is arranged in the light emitting direction of the display; the light splitting part is arranged on the light incident surface of the imaging lens group; the phase delayer is arranged on the light emitting surface of the imaging lens group; and the polarization reflection film is arranged on the side, away from the imaging lens set, of the phase retarder. According to the technical scheme, optical distortion can be reduced, and the imaging definition is improved.

Description

technical field [0001] The invention relates to the technical field of optical display, in particular to a near-eye display system and a head-mounted display device. Background technique [0002] The head mounted display device (Head Mount Display) sends optical signals to the user through various optical devices arranged inside, so as to display images at the position of human eyes, providing users with an immersive experience. During the transmission process of the light emitted by the display, the propagation path at the center of the display is different from the propagation path at the edge, so the final imaging picture at the position of the human eye is easily distorted and deformed. This distortion of the picture is distortion, and optical distortion will cause the picture The image resolution becomes lower. Contents of the invention [0003] Based on this, in view of the distortion of the imaging picture formed by the display in the current head-mounted display d...
