Rayprus, a manufacturer and integrator within the Foxconn group, showcases its light engine modules for AR smart glasses. The company focuses on the assembly and packaging of core components to create compact and thermally efficient light engines for both monochrome and full-color applications. Rayprus works with partners who supply the microLEDs and others who perform the final waveguide assembly, positioning itself as a key integrator in the AR display module supply chain.

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The company highlights its expertise in advanced packaging technologies designed to reduce the form factor of AR modules. One key technology is flip-chip assembly, which Rayprus claims can produce a module that is 50% smaller than traditional Chip-on-Board (COB) methods while offering superior heat dissipation. The demonstration included comparisons between a monochrome flip-chip module and a COB module, illustrating the size reduction achieved.
For achieving full-color displays, Rayprus combines RGB panels with a lens and what is referred to as an SQP assembly to create a full-color light module. The ultimate goal is to enable full-color AR smart glasses, which the company sees as the future of the market. The process involves integrating microLEDs from partners with a prism and lens into a compact module ready for waveguide integration.
In addition to its work on AR light engines, Rayprus is also a manufacturer of cameras and projectors. The company reports having existing customers for its camera modules, indicating a broader capability in optical and imaging system production. Their focus at Display Week is on promoting their integration capabilities for AR display modules, targeting potential customers developing next-generation smart glasses.
