Wincomn Technology has completed a complex rear projection upgrade in a command room at a military base in Guangdong Province, South China. They achieved this with the aid of advanced displays from dnp denmark, the world's leading supplier of optical projection screen technology. The display wall comprises three central 200” GWA (Giant Wide Angle) screens, butted together using narrow bezels, and flanked by a pair of GWA 150" screens.
The screens are projected onto by five EIKI projectors — creating a wide field of vision over a massive digital landscape, for military personnel assembled in the large 30m x 20m meeting room. The customer needed to present a large volume of information being streamed in different formats, including data, graphics, crystal clear high-resolution images, video and real-time signals. Existing switchers and processors were redeployed for the purpose and multiple windows and PIP’s can be presented across the screen. The display needed to be seamless, and although the client reviewed other options they favoured the high visual acuity and colour rendering of the GWA, as well as the uniformity over the large digital canvas. Purpose designed for the projection of large, high-quality images in conference and control rooms with long viewing distances, dnp’s 200” GWA became the world’s first optical rear projection screen when it was introduced. The single element optical system has two active lens surfaces, and due to its lens design offers good brightness uniformity and contrast levels. A spokesperson for the Command Hall said, “The screens perform excellently and look virtually seamless. “The climate in South China is severe, insofar as screens are subject to high temperature and high humidity. Every three months Wincomn will provide engineer site visits to check and adjust the alignment where the screens butt together, and this will ensure they remain in good condition.”
