At the 2025 World Artificial Intelligence Conference, Halliday unveiled its groundbreaking invisible display smart glasses and commenced pre-sales in Mainland China. These glasses stand out with their support for prescription lenses, a featherweight of just 28.5 grams, and an impressive battery life of up to 12 hours. Employing cutting-edge invisible display technology, these glasses appear indistinguishable from ordinary spectacles but offer a vivid 3.5-inch virtual screen. Designed with daily wearability in mind, they seamlessly integrate retro styling to cater to modern fashion trends. The glasses feature a myriad of functionalities, such as real-time translation, meeting summaries, and intelligent prompts, while an active AI assistant and an invisible control experience elevate their intelligence to new heights. Leveraging DigiWindow™ technology, they are priced at an initial cost of 2499 yuan, with anticipated shipments commencing in March 2026.
