At first glance, these walls look like they are reflecting light instead of actually producing it. The designer Jonas Sampson explained that the technology behind light emitting wallpaper is an old one, just applied in a different way. “The back layer is a silver-based solution that conducts electricity, while the layer above this contains phosphorous pigments that light up. On top of this is a flexible, transparent ITO conductor layer, with regular wallpaper placed on top to act as the final, outwardly visual layer.”
Neat as it maybe, I wonder how usable this type of wallpaper actually is. When the wallpaper is turned ‘off’, it looks just like a regular wall. Maybe the designer could add visual detail to it as well, when it is in off mode. Either way, it looks like a fun thing to have on your walls.
