Abstract
The invention discloses a contact lens type amplification module and a near eye amplification system. The contact lens type amplification module comprises a contact lens, wherein the center of the contact lens is provided with a through hole which is provided with a transparent layer; a polarization membrane is attached to the transparent layer; and the outer side of the through hole is provided with an optical lens of which the focal length is positive. The contact lens type amplification module has the advantages that a pinhole imaging principle is used for enabling an optical image to imageon a retina through the through hole, a distance between the amplification module and eyes can be guaranteed to be the closest, in addition, optical problems of aberration, distortion and the like are avoided, meanwhile, the optical lens arranged in front of the through hole is used to enable more rays of light to enter the through hole, and finally, a clear image with high luminance is formed.
Description
technical field [0001] The invention relates to the technical field of optical magnification, in particular to a contact lens type magnification module and a near-eye magnification system. Background technique [0002] The existing near-eye magnification systems on the market, such as smart VR devices, smart AR devices or other head-mounted display devices, must increase the radius of curvature of the convex mirror or increase the The distance between the convex mirror and the display screen, and the improvement results of these two schemes often lead to a very thick magnifying lens or an excessive distance between the lens and the screen, resulting in the entire near-eye optical magnification system being too bulky, making the entire near-eye display device The volume of the device is also too large, and it feels uncomfortable during use and wearing, which directly affects the use effect. [0003] Therefore, in order to provide a relatively good customer experience and red...
