Embodiment Construction

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] In the present invention, two structures "set in the same layer" means that the two structures are formed by the same material layer, so they are in the same layer in the layered relationship, but it does not mean that the distance between them and the substrate is equal, nor It means that they have the same structure as other layers between the substrates.

[0040] In the present invention, "patterning process" refers to the step of forming a structure with a specific pattern, which can be a photolithography process. The photolithography process includes forming a material layer, coating photoresist, exposure, development, etching, photolithography, etc. One or more steps in steps such as resist stripping; of cours...

Abstract

The invention provides a near-to-eye display device, a preparation method and wearable equipment, particularly relates to the technical field of near-to-eye display, and can at least partially solve the problem that the field angle of an existing near-to-eye display device is fixed and limited. The near-to-eye display device of the present invention comprises: a display panel; and a super lens unit which is located on the light-emitting surface side of the display panel. The super lens unit comprises a liquid crystal structure and a micro-nano structure layer, and liquid crystal molecules in the liquid crystal structure can deflect, so that the focus of the super lens unit can move within a first range; and the focuses of the super lens units fall into the plane where the panel is located.

Description

[0001] The invention belongs to the technical field of near-eye display, and in particular relates to a near-eye display device, a preparation method, and a wearable device. Background technique [0002] The AR / VR display headsets currently on the market are all very bulky and bulky. The metalens unit combined with the advantages of ultra-small size, high resolution, and high dynamic modulation range will be well applied in AR / VR systems, which can reduce the volume and weight of AR / VR display heads, become lighter. [0003] The existing AR / VR display headgear design is based on the combination of hyperlens unit and fiber optic scanning technology, which can be used to display complex and large-scale graphics larger than the focus range, but the ability to improve the field of view of AR / VR display headgear is limited. Contents of the invention [0004] The present invention at least partly solves the problem of limited viewing angle of the existing near-eye display device,...
