The invention discloses a near-to-eye display system and virtual reality equipment. The near-to-eye display system comprises an image source, an electric control liquid crystal lens, a first beam splitting lens, a magnification ocular lens, an eye diopter detection device, a storage device and a processor. The eye diopter detection device is used for detecting the eye diopter of a current user. The storage device is used for storing a first corresponding relation between the eye diopter and voltage applied to the electric control liquid crystal lens. The processor is used for controlling voltage applied to the electric control liquid crystal lens to be voltage corresponding to the eye diopter of the current user according to the first corresponding relation when the eye diopter of a current user is determined. The near-to-eye display system adopts the technical scheme of automatically adjusting a focal length by controlling voltage applied to the electric control liquid crystal lens, so that the complexity of structural design is reduced, and the weight of the near-to-eye display system is reduced.
Description
technical field [0001] The invention relates to the field of virtual reality, in particular to a near-eye display system and virtual reality equipment. Background technique [0002] Virtual reality (English: Virtual Reality; abbreviation: VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Users are immersed in the environment, bringing users a sensory experience beyond the real life environment. In terms of vision, virtual reality technology uses computer equipment to generate images of virtual scenes, and transmits image light to human eyes through optical devices, so that users can fully experience the virtual scene visually. [0003] At present, virtual reality devices such as head-mounted displays adjust the distance between the display screen and the optical lens through a mechanical structure for myopic user groups, so that the focus of light emitted from the optical lens is diffe...
