Embodiment Construction

[0036] Next, the technical solutions in the embodiments of the present invention will be described in contemplation in the embodiments of the present invention, and clearly, as described herein is merely, not all of the embodiments of the present invention. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention without all other embodiments obtained without creative labor.

[0037] It should be noted that all directional indications (such as above, lower, left, right, front, and then ...) are intended to be interpreted between the components under a particular attitude (as shown in the drawings). The relative positional relationship, the movement condition, etc., if the specific posture changes, the directional indication is also correspondingly changed.

[0038] In addition, as described in the present invention, as described in the present invention, it is only for the purpose of describing purposes...

Abstract

The invention discloses an optical module and a head-mounted display device, the optical module comprises a display, a cemented lens, a light splitting member, a quarter-wave plate and a polarization reflection film, wherein the display emits light for imaging display; the cemented lens is arranged in the light emitting direction of the display and comprises a first lens and a second lens, the first lens and the second lens are sequentially arranged in the propagation direction of a light path, the second surface of the first lens and the third surface of the second lens are arranged in a cemented mode, and the third surface protrudes towards the direction of the display. The fourth surface of the second lens protrudes towards the direction away from the display; the light splitting member is arranged on the first surface of the first lens; the quarter-wave plate is arranged between the first lens and the second lens; the polarization reflection film is arranged between the quarter-wave plate and the second lens. According to the technical scheme, the total optical length of the optical system can be reduced, the size of the head-mounted display device is reduced, and a user can wear the head-mounted display device conveniently.

Description

Technical field [0001] The present invention relates to the field of optical display, and more particularly to an optical module and a header display device. Background technique [0002] With advanced optical design and processing technology, display technology and processor development and upgrade, virtual reality (VR) products have emerged, and their application is also more extensive. The main working principle of the virtual reality product is that the image displayed by the display is received by the human eye by the transmission and amplification of the optical lens, and the human eye observed is an enlarged virtual image. The image is enlarged, and it takes a long enough optical path. Therefore, the optical system has a long optical system, resulting in a large size of the head-wear display device, not convenient to wear. Inventive content [0003] Based on this, the optical system of the existing head-wear display device is long, the head wear display device is large, a...
