TECNO has announced a new Starry Optical Fiber technology designed to revolutionize smartphone design. While not revealed at CES 2025, the technology is set to be fully unveiled at MWC 2025. This innovation aims to bring creativity back to smartphone design by implementing dynamic light patterns in the rear cover of devices. Contrary to its name, Starry Optical Fiber is not related to internet technology, but rather it combines ultra-fine optical fibers with mini-LED lights to create vibrant visual effects, like simulating a galaxy.
TECNO states the technology is suitable for both smartphones and tablets. The integration process involves 150 ultra-thin optical fibers, each 0.125 mm in diameter, and 108 LED lights. These components undergo over 30 manufacturing steps to ensure durability and proper function. The fibers are arranged in a loom-like structure on the phone’s rear cover, threading through 36 micro holes with a diameter of 0.7 mm and secured with a precise UV adhesive.
TECNO addresses potential battery drain concerns, asserting the light array is energy-efficient and consumes minimal power without compromising performance. The company also assures that the technology does not interfere with device heat dissipation systems. A customized PHANTOM V Flip2 5G foldable phone was showcased featuring the Starry Optical Fiber technology, demonstrating four lighting patterns: Tidal Waves, Rosy Sunset, Weekend Dusk, and Aurora. Details regarding the commercial availability of this phone variant are yet to be announced.
