A 220in dnp Supernova Infinity Screen has been used for a vandal-resistant outdoor display at the University of Southern California (USC). California-based CommCinema created the display, which faces due south and has to withstand bright natural light, not only from direct sunlight, but also from light reflecting from adjacent buildings.
CommCinema specialises in outdoor AV projects, but president Scott Tallal described the installation as: “one of the most challenging we have ever faced”. Physical constraints ruled out rear projection, and the bottom edge of the screen had to be 4.3m above viewing level, which restricted other projection options.
Tallal commented: “The conventional LED solution was way beyond the budget, so we had to draw on our experience of suitable ALR materials. We discovered that only dnp would warrant their product for a semi-protected outdoor installation. Other manufacturers were concerned about screen discolouration in direct sunlight.”
Ultimately, the 5 x 2.7 metre (2 x 2) dnp Supernova Infinity Screen was mounted in an open-fronted shadow box enclosure, tilted forward by five degrees to help compensate for the extreme viewing and projection angles. Setting the vertical lens shift to its maximum position on the Panasonic PT-DW11K projector all but eliminated the need for keystone correction.
