Description
Technical Field
The invention relates to the technical field of display equipment, in particular to an optical waveguide component and display equipment.
Background
Augmented Reality (AR) technology is a technology that skillfully fuses virtual information and the real world, and can be used in the real world after simulating virtual information such as characters, images, three-dimensional models, music, videos and the like generated by a computer, so as to supplement the real information in the real world and realize the 'enhancement' of the real world. The head-mounted display utilizing the augmented reality technology can enable people to project virtual images to human eyes while looking up the surrounding environment, and has important significance in the fields of military, industry, entertainment, medical treatment, transportation and the like.
In transmissive head-mounted displays currently used for augmented reality, the main technologies include: the Birdbath, prism, free form surface, and optical waveguide technologies, compared to other technologies, a head-mounted display using optical waveguide technology is smaller in volume. The optical waveguide technology mainly includes an array optical waveguide, a surface relief grating waveguide and a volume holographic waveguide, wherein the color expression and the light energy utilization rate of the array optical waveguide are superior to those of a diffraction optical waveguide and the volume holographic waveguide, and the array optical waveguide is widely applied.
In general, as shown in fig. 1, a one-dimensional array waveguide sheet includes a plurality of parallelogram prisms 1 'and a trapezoidal prism 2', and the plurality of parallelogram prisms 1 'and the trapezoidal prism 2' are arranged in a trapezoidal structure, and the trapezoidal structure has two parallel planes, one of which is an exit surface of the optical waveguide sheet. In actual processing, the parallelogram prism 1 'and the trapezoid prism 2' need to be glued together through optical cement, and then two parallel surfaces of the trapezoid structure are cut and polished until the height of the trapezoid structure reaches the product requirement. Due to the limitation of the processing technology, the optical cement between the parallelogram prism 1 'and the trapezoid prism 2' is oxidized by air and is affected by each device in the cutting and polishing processes, so that the optical performance of the surface layer of the optical cement on the emergent surface is different from the optical performance of the middle part of the optical cement, light rays incident to the surface layer of the emergent surface of the optical cement are scattered out of the optical waveguide sheet, and the phenomenon of 'propagation direction stray light' is not generated like pure reflection or transmission at other positions, so that the phenomenon of smearing (two sides of an image formed by the optical waveguide assembly are provided with fuzzy bright strips) is generated, and the imaging quality is reduced.
Accordingly, there is a need for an optical waveguide assembly and a display device to solve the above-mentioned problems.
