Description

Head display active type light transmittance adjusting MR glasses

Technical Field

The utility model belongs to the technical field of mixed reality technique and specifically relates to a head shows active regulation luminousness MR glasses.

Background

With the rapid development of the field of augmented reality and virtual reality, near-to-eye display equipment begins to be gradually popularized, but because the volume and the power limitation of the near-to-eye display equipment are limited at present, and the optical technology is not mature, the augmented reality equipment widely has insufficient brightness, and is difficult to clearly display when ambient light is strong (especially outdoors), so that a user can have a clear visual effect for ensuring that the user has, most of equipment adopts a shade with lower light transmittance, the influence of external ambient light on the display brightness is reduced, but the user is difficult to clearly see the real environment under the low-light environment, and the use experience is influenced.

The visual field of the user is completely sealed by the virtual reality equipment, the user cannot directly observe the real environment, and the visual field is transmitted through the camera to generate a serious diving goggles effect (as if the diving goggles are worn, the visual field is distorted and deformed, and the visual field is not matched with the space sense of naked eyes). Mixed reality experiences require users to observe the real physical world on the one hand, and on the other hand, require rich, clear images, interactive presentations at the same time. At present, because the display brightness of the optical module is not enough, the mixed reality scheme based on the augmented reality head display is very easily influenced by ambient light, and the optical module and the ambient light are difficult to combine.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a first active regulation luminousness MR glasses that shows solves current MR glasses's lens and receives the big problem of external light influence.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a head display active type light transmittance adjusting MR glasses comprises a glasses frame, lenses and an optical assembly, wherein the lenses comprise electrochromic layers, and transparent coating films are arranged on the surfaces of the two sides of each electrochromic layer; an optical sensor and a camera are embedded at the front end of the spectacle frame and are positioned right above the lenses; the embedded drive module that has of spectacle frame front end, drive module are connected with optical sensor, electrochromic layer, camera, optical component electricity respectively.

Preferably, the eyeglass frame is a one-piece assembly.

Preferably, the optical assembly is bonded to the lens and the spectacle frame respectively.

The utility model adopts the above structure MR glasses have following advantage:

1. the method can ensure that under different ambient light conditions, the real content can be simultaneously and clearly presented, and meanwhile, the sight of the user is not shielded.

2. The system can be supported to actively adjust the transmittance, and free control can be performed between the closed state and the perspective state by matching with the display content and the interaction requirement.

3. Because the transmittance can be adjusted, the real environment can be observed, and the vertigo and the discomfort brought to the user by the equipment can be greatly reduced.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

A head-display active transmittance adjustment MR eyeglasses as shown in the figure comprises an eyeglass frame 1, a lens 4 and an optical assembly 6. Spectacle frame 1 sets up to the integral type subassembly, and mirror leg 5 does not set up to folding mode, prolongs glasses life as far as possible.

The lens 4 includes an electrochromic layer 10, and both side surfaces of the electrochromic layer 10 are provided with transparent plating films 11. The front end of the spectacle frame 1 is inlaid with an optical sensor 2 and a camera 3, and the optical sensor 2 and the camera 3 are positioned right above the lens 4. The front end of the spectacle frame 1 is embedded with a driving module 8, and the driving module 8 is respectively electrically connected with the optical sensor 2, the electrochromic layer 10, the camera 3 and the optical component 6.

In this embodiment, the lens 4 is designed as a single piece, the lens 4 directly covers both eye sockets, and the inner electrochromic layer 10 is also provided as a single piece. Of course, the electrochromic layer 10 may be provided in two pieces, each piece of the electrochromic layer 10 being separately adjusted.

The optical assembly 6 is respectively bonded with the lens 4 and the spectacle frame 1. A certain space is reserved between the front end of the spectacle frame 1 and the front end of the optical component 6, so that the front ends of the lenses 4 are aligned with the front end of the spectacle frame 1, and the aesthetic degree of the spectacles is improved.

When a user 9 wears the glasses, the optical sensor 2 automatically collects the ambient brightness and transmits the signal to the driving module 8, and the computing unit in the driving module 8 analyzes the ambient brightness, so that the transmittance of the electrochromic layer 10 and the display brightness of the optical module 6 are adjusted, and the virtual image and the sight of the user 9 are not influenced.

To sum up, the utility model adopts the above structure head shows active regulation luminousness MR glasses, and the active lens transmissivity of adjusting does not take place to shield user's sight, has improved user's use comfort.

The above are specific embodiments of the present invention, but the scope of protection of the present invention should not be limited thereto. Any changes or substitutions which can be easily conceived by those skilled in the art within the technical scope of the present invention are covered by the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the claims.
