Our first reaction to this was to think just how wildly unnecessary "e-skins" are, but then we saw that slide up there and started to see the (electronic) light. Philips appears to have struck upon its own version of Kent Displays' electronic skins
, which requires no backlighting, operating by reflecting ambient light instead. Based on similar tech to e-books
, this invention is initially targeted at generating colorful covers for things like mobile phones and mp3 players, but it's said to be "highly scalable" and e-wallpapers and light-dimming windows could be on the cards if things continue developing. And of course, no "water cooker" would be left behind.
