[0113] The third example of the head-mounted display device provided by the embodiment of the present invention is suitable for application scenarios with a small exit pupil distance. The head-mounted display device includes: a casing, and an optical imaging system arranged in the casing, such as Figure 7 As shown, the optical imaging system includes: an image display S1, a lens part S2, a first reflection part S3 and a second reflection part S4, wherein the lens part S2 includes a meniscus lens 503 and a plano-convex lens 504, and the plano-convex lens 504 is located at the meniscus lens 503 between the image display S1. The internal space of the head-mounted display device also includes the space where the human eye that forms an optical path with the optical imaging system is located, and the space where the human eye is located is indicated by the exit pupil position S5. Wherein, the relative positional relationship between the second reflection part S4, the first reflect...

The invention discloses a head-mounted display device which comprises a housing, and an optical imaging system arranged in the housing. The optical imaging system comprises an image display, a lens portion, a first reflecting part and a second reflecting part, wherein the lens portion is arranged in front of the image display, the reflecting surface of the first reflecting part is arranged opposite to the light exit surface of the lens portion, and the reflecting surface of the second reflecting part is arranged opposite to the reflecting surface of the first reflecting part. Light emitting from an image display entering into the lens portion, and then into the eyes of the wearer of the head-mounted display device after being refracted by the lens portion and reflected by the first reflecting surface of the first reflecting part and the reflecting surface of the second reflecting part, so that the wearer can see the image. The optical imaging system of the head-mounted display device is flexible in design and easily realize large field angle. The installation positions of optical elements are scattered. The assembly is simple, and the head-mounted display device is easy to produce.
Description
technical field [0001] The present invention relates to the technical field of head-mounted display imaging, in particular to a head-mounted display device. Background technique [0002] In recent years, head-mounted display devices have developed rapidly along with the development of optics, electronics and other fields. The head-mounted display device has a built-in optical imaging system. The optical imaging system enables the wearer of the head-mounted display device to view the image information displayed on the display screen through the combination of optical components such as a display and an optical lens. [0003] In the current head-mounted display devices, in order to correct aberrations and ensure the quality of optical imaging, the optical imaging system has a large number of optical components, which have problems such as large size, heavy weight, and unfavorable wearing. Under the circumstances, the overall design of the optical imaging system is relatively ...
