14 DAY TRIAL // We all love big screens? the bigger, the better. But what do you think about one that has the size of three tennis courts put side by side? It?s great, isn?t it?
But someone really created it - Mitsubishi Electric ? which announced that it has delivered and installed it?s screen, the world?s largest high-definition video screen. Moreover, the screen was divided into 35 pieces in order to be delivered from Mitsubishi?s Nagasaki-based factory to the Tokyo Racecourse in Fuchu, Tokyo.
?The screen employs Mitsubishi?s Aurora Vision LED technology and measures 11.2 meters (37 feet) x 66.4 meters (218 feet), giving it a surface area of 744 square meters (8,000+ square feet), or the equivalent of 3 tennis courts. The bright, high-definition display is 3 times larger than what was previously installed at the horse track, and the screen?s three sections allow the audience to take in the action at other tracks. Total cost is reported to be 3.2 billion yen (US$28 million),? informed Pink Tentacle web site.
But this is not the sole innovative screen, as the German researchers from the Technical University of Braunschweig have conceived in their labs an entirely transparent OLED (organic light emitting diode).
Their approach is to use transparent TFTs (thin-film transistors) made of a 100-nanometer-thick layer of zinc-tin-oxide, which transmits more than 90 percent of visible light. Such transistors are more often made of silicon, which is used for LCDs (liquid crystal displays) but is highly absorptive in the visible part of the spectrum.
Transparent displays could have numerous applications, including screens that supply surgeons with additional information in their field of view or car windshields that allow drivers to view directions, according to Riedl.
