WiMi announced the patent of holographic AR head-mounted display , by using retina scanning display (RSD) and semi-permeable membrane array planar waveguide technology

BEIJING, April 27, 2021 /PRNewswire/ -- WiMi Hologram Cloud Inc. (Nasdaq: WIMI) ("WiMi" or the "Company"), a leading Hologram Augmented Reality ("AR") Technology provider, today announced that it has obtained a patent for head-mounted display (HMD) for holographic AR systems. This patent is the result of the independent research and development, which is conducive to further improve the intellectual property protection system, maintain the leading position in technology and enhance the core competitiveness of the Company.


This patent proposes a HMD for holographic AR system, which realizes the immersion required by holographic application and can send head movement data and external image information to the upper computer. It comprises a holographic data collection and transmission module and a micro-display module. The holographic data collection and transmission module includes an image sensor, a gyroscope, an accelerometer, a Bluetooth module and a processor. It completes the collection of head movement data and holographic image information of a real scene, and transmits the collected holographic data to the micro-display module for further data processing. The micro-display module includes a micro-control module as the holographic AR data output of the system.


In this patent, a holographic exit pupil expander is used to effectively expand the holographic exit pupil in two dimensions, which can improve the system performance and realize portability while meeting the visual requirements of human eyes. This patent calculates the physical law of holographic exit pupil expansion through the holographic exit pupil expansion algorithm technology of retinal scanning display (RSD) and semi-permeable membrane array slab waveguide, which obtains an effective dynamic algorithm for expanding holographic exit pupil. The physical mechanism of limiting holographic exit pupil is calculated from the perspective of optical system design. The diffraction integral transformation method is used to process the diffraction grating holographic exit pupil expander and the micro-lens array holographic exit pupil expander, which provides data support for the movement of the holographic exit pupil expander. By using optical simulation algorithm modeling, dynamic calculation of holographic exit pupil expansion trajectory of hexagonal single lens array and double lens array, accurate algorithm of color display RSD holographic exit pupil expansion are realized combined with double lens array, and finally the immersion high-definition holographic AR data imaging are applied.


This patent uses a HMD optical system to digitize and holographically image the output of a computer-generated holographic AR image source in the user's field of vision, which realizes the simulation technology of reproducing a specific environment. The patented immersive head-mounted AR display technology has the advantages of large field of view, low power consumption, wearability, modularization, stereoscopic display, high degree of customization, etc. It will be widely used in telemedicine, industrial construction, environmental simulation, traffic indication, virtual education, holographic communication, 3D printing, assisted driving, etc. in the future.
