When it comes to displays you've got LCDs, LEDs, and OLEDs; now make way for Hairy-Ds.
Electronics giant Philips has filed a patent for an as-yet-unnamed "display fabric" that operates by controlling hairs. Each pixel is made of fabric of a certain color, and embedded with hairs of a different color. When the hairs lay flat, all you see is their color; apply an electrostatic charge and the hairs stand up, revealing the color of the fabric beneath.
The initial applications are forecasted to be clothing with changeable displays on them, as there doesn't seem to be any use in having furry flatpanels. So we can continue to clean our laptop screens with electrostatic rags rather than, say, Pantene Pro-V.
