the largest color LED display worldwide, & the first photo-voltaic system integrated into a glass curtain wall in China. the display requires zero external energy, as the facade harvests solar energy by day & uses it to illuminate the screen after dark. the display comprises of 2,292 color (RGB) LED's light points comparable to a 24,000 sq. ft. (2.200 m2) monitor screen for dynamic content display.

the polycrystalline photovoltaic cells are laminated within the glass of the curtain wall & placed with changing density on the entire building's skin. the density pattern increases building's performance, allowing natural light when required by interior program, while reducing heat gain & transforming excessive solar radiation into energy for the media wall.

you can play with the online simulator, or watch a movie after the break.

Nice one. But the animations do not look very exciting. One have seen this many times before.

Not sure why people are calling this the largest color LED screen in the world... it pales in comparison to http://en.wikipedia.org/wiki/Fremont_Street_Experience#Viva_Vision. 2,292 color LEDs is nothing compared to 12 million (even if you consider 4 LEDs per pixel).

Nice, but how long until it's 100% advertising?

It must be that having fewer leds/pixels per square foot makes the screen more energy efficient.

this is so awesome. all powered by solar energy.
now imagine how much energy we´d save if we´d use Solar powered LEDs as our street lighting.
it would be tremendous !

It would be great to see this technology integrated into new high-rise developments. It doesn't need to be the entire face of a building but perhaps just some esthetically pleasing accent lighting.
