Abstract

The invention provides a head-mounted display device. The device comprises a first positive lens, a second positive lens and a micro-display device which are coaxially arranged in sequence; the lightinlet surface of the first positive lens is close to the light outlet surface of the second positive lens, and the light inlet surface of the second positive lens is close to the micro-display device;the light outlet surface of the second positive lens is a convex Fresnel surface, and the light inlet surface of the first positive lens is a plane Fresnel surface. According to the head-mounted display device, the size can be reduced, and meanwhile the view field angle is effectively increased.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a head-mounted display device. Background technique [0002] VR (Virtual Reality, Virtual Reality) technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment, and through multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior The system simulation immerses the user in this simulated environment. With the development of technology, VR head-mounted display devices have been widely used in fields such as games, real estate, and tourism. [0003] At present, one type of VR head-mounted display device uses a mobile phone screen as a display screen, which is limited by the size of the mobile phone screen (2 to 5 inches), and the size of the VR head-mounted display device cannot be made small, which is not conducive to the user's long-term W...
