Problems solved by technology

At present, commonly used light-emitting displays include LCD (Liquid Crystal Display, liquid crystal display) and OLED (Organic Light-Emitting Diode, organic light-emitting diode display), among which LCD screen has high resolution (up to 4K resolution), but the response speed Slow, there is a considerable delay, and the application of virtual reality equipment will bring obvious dizziness to the user; the OLED screen responds quickly, but due to cost and process constraints, it is difficult to achieve a higher resolution, resulting in single-pixel correspondence The angular resolution is far greater than the angular resolution of the human eye, giving users a screen window feeling
[0004] In view of the above problems, the method of reducing the field of view of the virtual reality device is generally used to improve the angular resolution of the virtual reality device, but reducing the field of view will reduce the immersion of the human eye and reduce the user experience.

Embodiment 1

[0026] figure 1 This is a schematic diagram of a monocular display device of a virtual reality device according to Embodiment 1 of the present invention. The virtual reality device includes a monocular display device. The monocular display device includes: at least two first display screens 110 and a first lens 120.

[0027] The first lens 120 includes an exit surface 121 and at least two first entrance surfaces 122. The first entrance surface 122 is arranged corresponding to the first display screen 110 and is used to receive virtual image light emitted by the first display screen 110. The exit surface 121 is used for setting corresponding to the human eye; the first lens 120 is used for adjusting the optical path of at least two virtual image light rays that are incident, so that at least two virtual image light rays emitted from the exit surface 121 are superimposed on the human eye imaging surface. Virtual image.

[0028] Among them, the display screen refers to a display tool ...

Embodiment 2

[0048] figure 2 It is a schematic diagram of a monocular display device of a virtual reality device according to the second embodiment of the present invention. Based on the foregoing embodiment, the monocular display device 100 further includes: at least one second display screen 210 and at least one second lens 220; among them:

[0049] The second display screen 210 is used to emit virtual image light;

[0050] The first lens 120 further includes a second incident surface 123, which is spaced apart from the first incident surface 122;

[0051] The second lens 220 is located between the second incident surface 123 of the first lens 120 and the second display screen 210;

[0052] The second lens 220 and the first lens 120 are used to adjust the optical path of the virtual image light incident on the second display screen 210 so that the virtual image light emitted from the exit surface 121 forms a virtual image on the imaging surface of the human eye.

[0053] Optionally, each first ...

Abstract

An embodiment of the invention discloses virtual reality equipment. The virtual reality equipment comprises a monocular display device. The monocular display device comprises at least two first display screens and a first lens, wherein the first lens comprises an emergent face and at least two first incident faces, the first incident faces correspond to the first display screens and used for receiving virtual image light transmitted by the first display screens, and the emergent face corresponds to the human eye; the first lens is used for regulating the optical path of at least two incoming virtual image light to allow the at least two virtual image light going out from the emergent face to overlay on a human eye imaging face to form virtual images. The virtual reality equipment has the advantages that the problem that existing virtual reality equipment is high in screen window sense is solved, the resolution of the virtual reality equipment is increased, and the screen window sense is reduced.

Description

Technical field [0001] The embodiment of the present invention relates to optical technology, in particular to a virtual reality device. Background technique [0002] With the continuous development of virtual reality technology, virtual reality devices are increasingly accepted by users. [0003] Current virtual reality devices mostly adopt a design scheme in which both eyes share one display screen or one eye corresponds to one display screen. Currently commonly used light-emitting displays include LCD (Liquid Crystal Display, liquid crystal display) and OLED (Organic Light-Emitting Diode, organic light-emitting diode display). The LCD screen has high resolution (up to 4K resolution), but has a high response speed. Slow, there is a considerable delay. When applied to virtual reality devices, it will give users an obvious sense of vertigo; OLED screens respond quickly, but due to cost and process constraints, it is difficult to achieve higher resolution, resulting in single pixel...
