Innovation Summary:
This invention relates to methods and devices for transceiving light via display devices, enabling bidirectional optical communication. The light source array can operate in multiple duplexing modes: full-space-division, half-space-division, and time-division duplexing. By integrating communication functions into display devices, the invention allows them to double as data transmitters and receivers. The design includes pixel-level or group-level control, allowing scalability and flexibility in implementation. This approach supports high-speed optical communication, enabling devices like smartphones, monitors, or AR/VR headsets to communicate directly using their displays. The innovation merges display and communication technologies, opening new possibilities for compact, energy-efficient devices.

Challenges / Opportunities:
Challenges involve miniaturization of control electronics and integration without compromising display quality. Battery efficiency and managing heat in compact devices are also critical. Standardization for optical communication protocols will be necessary. Opportunities include enabling new communication paradigms where displays function as communication nodes. It could reduce reliance on radiofrequency spectrum, offering secure, high-bandwidth connections. Potential applications include device-to-device communication, IoT systems, augmented reality, and smart environments. By merging optical communication with everyday displays, this technology could become widely adopted in consumer electronics.
