X Display Company (XDC) has launched a revolutionary display with a speed of one million frames per second, the fastest reported so far. This innovation paves the way for advanced optical wireless communication systems, enhancing connectivity in AI data centers with scalable, cable-free, and energy-efficient display-camera links.
XDC displays are engineered for machine-to-machine communication, utilising thousands of ultrafast, multi-wavelength and parallelly transmitting emitters. The system dynamically writes and controls data across discrete sequential frames, each frame optically transmitted by the display and then read by a high-speed camera receiver. Modelling of the link’s energy efficiency shows a roadmap for 2–3x improvement in power-per-bit (pJ/bit) compared to 800G optical transceivers — a significant advantage for hyperscale data centres seeking greener and more reconfigurable infrastructure.
“We’re seeing concepts and elements of microLED display technologies getting ready to serve the data centre optical communications market and positioning to transform the interconnectivity inside data centres,” said Eric Virey, PhD, Principal Display Market and Technologies Analyst within the Photonics, Sensing and Display division at Yole Group. With the advent of AI and the rise of neural networks, more scalable and sustainable connectivity solutions will alleviate the burden on energy, networking infrastructure and the total cost of ownership (TCO) for hyperscale data centres. XDC’s display-based optical link enables data to fly — quite literally — through air, eliminating the need for physical fibre bundles to form xPU clusters, while also adapting dynamically in real-time to changes in bandwidth demand.
“This breakthrough ushers in a wholly new paradigm where displays transcend their traditional role as mere interfaces for humans, evolving into optical data transmitters between machines,” said Nikhil Jain, Director of OptoElectronics and Strategic Partnerships at X Display. “The capacity to dynamically transmit data at megahertz speeds through the air holds transformative promise for cloud infrastructure. Looking ahead, with continued innovation, terabit-per-second and beyond bandwidths are within reach—facilitating scalable, modular, and energy-efficient optical communication, and paving the way for pioneering applications such as optical computing.”
The platform is not only a compelling optical data communication solution but also offers building blocks for applications spanning LiFi, digital media broadcasting, visible light communication (VLC), vehicular ad hoc networks (VANET) and energy-efficient optical compute.
