$Appotronics: Single-Engine Binocular LCoS Light Engine for AR Glasses Appotronics presents its single-engine binocular display LCoS (Liquid Crystal on Silicon) light engine for AR glasses. This architecture uses a single LCoS panel and light engine to drive a display for both eyes, which can reduce cost, power consumption, and size. The system can be configured for full-color RGB or single-color (e.g., green) output, suitable for different applications from 3D content to simple daily reminders. 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 single-engine design achieves binocular vision by splitting the pixels of the display panel. Half of the panels pixels are directed to the left eye and the other half to the right eye. This allows for the display of stereoscopic 3D content, as each eye receives a slightly different image, similar to the effect used in 3D cinemas. The system is also capable of showing the same image to both eyes for applications like reading text where clarity is paramount. The switch between 3D and 2D modes is managed by the video stream sent to the glasses. The demonstrated prototype features a 25-degree diagonal field of view with a resolution of 640x200 pixels, paired with a diffractive waveguide. Appotronics emphasizes that for AR applications, pixels per degree (PPD) is a more critical metric than raw resolution. While 4K resolution in a compact AR form factor is challenging with current technology, the company sees a path to full HD before targeting 4K. The design allows for digital adjustment of the display area if a larger panel is used. Appotronics focuses on the system architecture and light engine design, partnering with other companies for waveguide manufacturing. The technology is compatible with various waveguide types, including diffractive and geometric waveguides. The light source for the engine can be either LED or laser-based, with laser versions being developed in partnership with other firms. The primary benefits for the end-user are cited as cost-effectiveness, thinness, and light weight. Based in Shenzhen, Appotronics positions its technology as a key enabler for consumer-grade, everyday AR glasses. The company notes that while MicroLED and LCoS technologies will likely coexist to serve different segments of the AR market, their single-engine LCoS approach offers a compelling solution for creating affordable and accessible binocular AR experiences. The cost of the dual waveguides remains a factor, but the single engine helps offset the overall system cost.$
