pixels             …everywhere.

Big beautiful blurry pixelized walls…

My friend Jordan Priede told me about a recent announcement from Philips about LED-illuminated wall coverings which they worked on with Kvadrat Soft Cells. Think of it as LED-illuminated wallpaper targeted at commercial spaces, and it could be a very important step toward the digital light future.

What they’ve done is embed addressable LEDs — I’m guessing pretty low resolution– into a semi-opaque wall covering. Now ordinarily low res LEDs look really awful, especially close up. All you normally would see close up are bright LED points of light that are way too bright–  I certainly wouldn’t want them in a restaurant or lobby.

The clever thing with the Kvadrat/Philips product is that the fabric on the wallpaper blurs the LEDs. Conventional thinking is that blurring is bad, but in this case it makes the image look continuous. Contrast is low and it’s no good as-is for text, but it looks like it might actually work nicely for combining illumination with mood. The video below shows the idea better than the photos do.

If it’s as good as the photos and video in the announcement make it appear, this could actually be useful even in bright environments. This really is a kind of digital light.  I’m sure it won’t be low-cost initially, but low resolution LED displays are dropping in price fast and that bodes well for this sort of application.

Energy Use for Large Outdoor Displays Improving

by on Jul.12, 2011, under energy use, LED/OLED

I’ve commented several times that pixels won’t be everywhere unless power consumption significantly drops. David Haynes over at the sixteen:nine blog wrote an interesting article about energy consumption improvements in electronic billboards. The good news is that the industry claims a significant improvement (in part based on using them in smarter ways); the bad news is that energy consumption is still very high.
