Great Chinese monitor.
GreenPix - the so-called grandiose building, built in Beijing for the Olympic Games - 2008.
According to the official website of the project, this is the world's largest display with a total area of 2,200 m 2 , consisting of 2.292 RGB LEDs. The screen is mounted on the facade of the Xicui Entertainment Complex, which opened on June 24, 2008.
But the most curious is not even in size. The full name of the project is “GreenPix - Zero Energy Media Wall”. According to US-German developers, the glass contains "polycrystalline photovoltaic cells" with a variable density model. This allows them to pass light during the day, collecting excess heat, and at night emit the same energy in the form of a glow. Thus, the building is protected from overheating, and the wall works in non-volatile mode.
True, talking about high resolution is not necessary - one pixel takes a little less than a square meter. But the creators of the new technology are not discouraged, believing that it “provides specific artistic opportunities compared to conventional high-resolution media facades”
