Embodiment 1

[0032] Such as Figure 1~4 As shown, the head-mounted display provided by this embodiment includes a glasses case 1 , dichroic prisms 2 respectively located in the glasses case 1 and two sets of lens groups 3 for imaging.

[0033] The cross section of the dichroic prism 2 is an isosceles triangle.

[0034] Each lens group 3 includes a concave lens 4 and a convex lens 5 , and the convex lens 5 is located right behind the concave lens 4 .

[0035] The end of the spectacle housing 1 facing the face of the human body is the viewing end, and the end far away from the human face is the projection end, and the dichroic prism 2 and the lens group 3 are sequentially arranged between the projection end and the viewing end. Wherein, two sets of lens groups 3 are arranged symmetrically along the median vertical line of the cross-section of the dichroic prism 2, and the two convex lenses 5 are respectively arranged on the viewing end.

[0036] Such as figure 1 As shown, the glasses casi...

Abstract

The invention discloses a head-mounted display. The pair of glasses comprises a glasses shell, a beam splitter prism and two lens groups, the cross section of the beam splitter prism is an isosceles triangle; each lens group comprises a concave lens and a convex lens; the convex lens is positioned right behind the concave lens; the end, facing the human face, of the glasses shell is a viewing end,the end, away from the human face, of the glasses shell is a projection end, a beam splitter prism and lens sets are sequentially arranged between the projection end and the viewing end, the two lenssets are symmetrically arranged along the perpendicular bisector of the cross section of the beam splitter prism, and the two convex lenses are arranged at the viewing end. According to the invention, the projected video does not need to be recorded and adjusted by professional equipment, the video playing cost is reduced, the universality is relatively high, and the application range of use is expanded; besides, light is directly projected to the retinas of the human eyes through the beam splitter prism and the lens group to form virtual images, people with myopia and hyperopia can also watch the virtual images with naked eyes, and the use experience is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality head-mounted display devices, in particular to a head-mounted display. Background technique [0002] Virtual reality head-mounted display equipment, referred to as VR head-mounted display VR glasses, is a product that uses simulation technology and computer graphics man-machine interface technology multimedia technology sensor technology network technology and other technologies. It is created with the help of computers and the latest sensor technology. A brand-new means of human-computer interaction. [0003] The existing VR glasses are mainly equipped with a display screen and a pair of lenses, which are used to directly project the displayed content into the human eyes, so as to achieve the effect of visually immersive. The development of VR glasses has gradually matured, but there are still the following deficiencies in display: (1) At present, most VR glasses can only display the con...
