Toshiba OLED Video Wallpaper Powered By SF
Toshiba has been working on what science fiction writers call video wallpaper - a thin covering for large walls that could be used for illumination and color scheme (at a minimum) and full-wall, full-motion video at the far end of the scale.
The breakthrough in wall coverings is the result of improvements in organic electroluminscence (OLED) screen technology, according to Toshiba, that enables the paper to emit light.
"OLED is anticipated to become an important light-emitting device for the next generation," Toshiba said in a statement.
The problem that the scientists have had to overcome is increasing the efficiency of existing OLED devices, such as televisions that use the reduced-energy material. To achieve that, the wallpaper uses light that has been redirected by an ultra-fine grating that is fabricated by self-assembled nano particles, said Kaori Hiraki, a Toshiba spokesman.
Toshiba's work is still in the research phase; Toshiba says it is years away from a commercial product.
The first direct use of this idea that I know about is the video wallpaper from the 1999 novel A Deepness in the Sky by Vernor Vinge. Another example is the smart wallpaper from the 2003 novel Oryx and Crake by Margret Atwood.
Take a look at some of these other real-life efforts to make video wallpaper a viable commercial product:
- Shinoda Plasma Video Wallpaper
- Roll-to-Roll Processing OLEDs And Video Wallpaper
- Digital Daewoo Folding Screen DID-FS
