Description: Universal smartphone holder exploits the hardened organic glass to prevent scratch and project navigation information onto the panel based on optical reflection theorem. When placed on the center console, drivers don't need to bow to see because it will not block sight. Thus drivers could pay more attention to the road conditions nearby. Meanwhile, the design avoids the drivers observing the distant road conditions, which makes the navigation information more visualized and thereby improves the driving safety.
