Tecno's latest concept phone is lit by neon

"The Pova Neon includes genuine neon lighting, not just bright colors: it uses "ionized inert gas lighting technology" to create a glowing effect. By contrast the AI EInk builds color electronic ink into the rear of the phone, allowing you to change the phone's color on the fly."

"Perhaps more impressively, you're able to set the color using the camera, so you could make your phone match your outfit with a single snap. As with any concepts, there's no guarantee we'll ever see Tecno release a real phone with either design, and the neon feels particularly unlikely to ever hit the market."

Tecno introduced two innovative smartphone concepts with color-changing finishes. The Pova Neon incorporates genuine neon lighting through ionized inert gas technology to create a glowing effect on the device. The AI EInk model features color electronic ink on the rear, enabling users to change the phone's color dynamically. The E Ink version includes a camera-based color-matching feature, allowing users to photograph their outfit and automatically adjust the phone's color to match. While both designs represent forward-thinking concepts, the neon variant faces significant manufacturing challenges and market viability concerns, though the E Ink color-changing phone appears more feasible for eventual commercial release.
