General Motors is pursuing a self-cleaning solution for car media displays that aims to reduce fingerprint smudges on touch screens. Autoevolution reports that this technology could keep in-cabin screens clearer with less maintenance, a welcome feature for drivers who rely on touch interfaces while on the road.
The proposed system would complement a multicolor LED setup that includes red, blue, and green diodes. In addition, GM is looking at purple diodes capable of emitting ultraviolet radiation that remains invisible to the eye. This combination of lighting elements could play a key role in the screen cleaning process, potentially enhancing how the display is refreshed during normal vehicle operation.
A major component of the plan is a photocatalytic coating applied to the screen surface. This coating would absorb light and trigger chemical reactions that help loosen and lift fingerprints and other contaminants. The result is a cleaner viewing area without the need for manual wiping. Importantly, the ultraviolet light from the diodes could be activated even when the vehicle is dark, adding a round-the-clock cleaning capability that would work with or without ambient lighting.
The report also mentions that Nissan has previously introduced features related to the Nismo variant of the Patrol, a reference that provides context for automakers exploring performance and feature-rich trims in popular SUV models. The broader takeaway is that major manufacturers continue to explore integrated display care technologies alongside vehicle design innovations to improve user experience and maintain display clarity over time.
