[{"type":"text","content":"BEIJING, June 28, 2023 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (\"WiMi\" or the \"Company\"), a leading global Hologram Augmented Reality (\"AR\") Technology provider, today announced the development of an ultra-thin interactive panel holographic display system based on the steering backlight unit (S-BLU) and the holographic video processor. It is planned for commercial display, which will completely change the application landscape of holographic displays.\nCurrently, conventional holographic display technology with narrow viewing angles, bulky optical components, and a lack of dedicated hologram computing units leads to the low processing capability of holograms. WiMi proposes an interactive ultra-thin panel holographic display system using an S-BLU and a holographic digital image processor to solve the above problems. WiMi's S-BLU greatly expands the viewing angle, and its diffractive waveguide architecture enables a slim display profile. The holographic video processor computes high-quality holograms in real-time on a single chip.\nThe holographic display system, which includes the S-BLU, consists of a coherent BLU and a beam deflector (BD). It increases the SBP (Spatial Bandwidth Product) multiple times using S-BLU. All optical components are designed and manufactured with ultra-thin structures. The 8K UHD hologram is achieved by dedicated holographic digital image processing through a single-chip FPGA processor. Its optical architecture consists of a beam deflector, a coherent backlight unit, a geometric phase lens, and a spatial light modulator. The principle is a coherent backlight unit configuration using waveguides: the first waveguide for the red and green light and the second waveguide for blue light are stacked together to improve the overall efficiency.\nThe system updates the 3D image based on the position of the viewer's eyes as detected by the eye-tracking sensors. A graphics rendering or 3D holographic camera generates a corresponding 3D holographic digital image. Based on the image on the retinal plane, the holographic digital image processor calculates the light field distribution on the eye lens plane. Then, based on the light field distribution on the eye lens, the holographic pattern of the optimal SLM is calculated to generate high-quality holographic images for the application scenario an...
