TECNO has brought a new technology to CES 2025 that, if popularized, could revolutionize smartphone design as we know it. In today’s industry, the standardized form factor of smartphones leaves very little room for creativity, so brands must carefully look for parts of the device to add their personal touch. With that in mind, the new Starry Optical Fiber technology is implemented in the rear cover of your phone.
Despite what its name might suggest, TECNO’s Starry Optical Fiber has nothing to do with the internet. It is a technology designed to implement intricate dynamic light patterns in phone designs. It is based on a combination of ultra-fine optical fibers with mini-LED lights. The output is a vibrant visual effect that can simulate the appearance of a galaxy, among other inspirations.

TECNO claims that its technology is compatible with both smartphones and tablets. The integration of the 150 ultra-thin optical fibers (0.125 mm in diameter) and 108 LED lights goes through more than 30 meticulous manufacturing processes to ensure their durability and correct functioning. The set of fibers forms a kind of “loom” on the rear cover of the device, threading through 36 micro holes with a diameter of 0.7 mm. A precise UV adhesive also ensures that everything stays where it should be.
You may be thinking that a system on the back of your phone that is always lit up can quickly drain its battery. However, TECNO asserts that they designed the light array with energy efficiency in mind. It consumes very little power without sacrificing performance. The firm also guarantees that it does not interfere with the heat dissipation systems of mobile devices.
TECNO showed a custom PHANTOM V Flip2 5G foldable phone at CES 2025 with the Starry Optical Fiber technology. Currently, the phone supports four lighting patterns: Tidal Waves, Rosy Sunset, Weekend Dusk, and Aurora. There are no details yet about the possible commercial availability of this variant of the device.
