 The new possibilities offered by these developments have prompted some designers and companies to research and develop proprietary LED wallpaper technologies, some of which are currently available for commercial purchase.Other solutions mainly exist as prototypes or are in the process of being further refined.The first use of the term "LED wallpaper" is found in the book "Wallpaper" by Lachlan Blackley, describing the work of textile designer Maria Yaschuk, who designed a flexible solution to incorporate LEDs into digitally printed wall covering material in 2004.
