Description

AR optical module shading structure and AR glasses
Technical Field

The utility model also relates to AR glasses with the AR optical module shading structure.
Background
The AR technology, english Augmented Real ity Chinese, is an augmented reality technology, which is a technology that calculates the position and angle of a camera image in real time and adds a corresponding image. The method is a technology for fusing virtual content and real content in real time to form interaction between virtual and reality.
And VR technology english is Virtual Real, chinese is Virtual reality, which is a technology for providing immersion feeling in an interactable three-dimensional environment generated on a computer by comprehensively utilizing a computer graphics system and various interface devices such as reality and control.
With the progress of imaging technology, there is an increasing demand for immersive experience, and in recent years, development of VR/AR technology gradually satisfies pursuit of people for visual experience. The head-mounted device can liberate hands of people, reduce dependence on a screen and create better visual effects. For head-mounted devices, near-eye display is a key to its technology, and imaging quality and thinness are major considerations. Near-eye display systems generally consist of an image high-low beam transmission system, through which an image frame emitted by an image source is transmitted to the human eye. In this case, unlike VR, which requires an external environment, AR needs to be used outdoors, so that the wearer needs to protect external glare while viewing the image.
There are many schemes for shielding the light of the optical module. More common is external black lens structure, and external color-changing lens is externally added on the outermost side of AR lens, and when the external black lens structure is used outdoors, the external color-changing lens structure can be used for protecting the AR lens from strong light, and if the external color-changing lens structure is not used outdoors or is not needed in the weather, the external color-changing lens structure can be removed to cancel the protection from strong light, so that the AR lens is lighter and thinner. The external color-changing lens such as the external sunglasses lens has the advantage of reliable structure, is obviously superior to the structure without shading, and becomes a main flow path of various large companies.
The disadvantage that most AR products at present adopt the shading structure of the externally hung ink lens is also existed, firstly, a gap is arranged between the externally hung ink lens and the optical waveguide lens, and the gap is easy to accumulate dust and then influence the imaging effect. The other disadvantage is that the installation of the externally hung ink lens during use can influence wearing comfort and experience, optical distortion possibly occurs due to gaps, the weight of the AR glasses is increased as a whole, and the externally hung ink lens is too large in action and falls off during wearing.
