评语：
With an ultra fine pitch of 0.065mm and vertical resolution of 20K lines (100-inch screen in 4:3 format), DNP's
Supernova front-projection screen provides markedly improved contrast in brightly illuminated rooms. The DNP
Supernova screen is ideal for conference rooms, POS environments, and home theater applications, according to the company. It is said to deliver an extraordinary 10X higher contrast and 2X brighter images than standard front screens.
In the demo, the Supernova screen was butted up alongside a competing screen with a projected image overlapping both, and contrast measurements were made under ambient light conditions. On the
Supernova screen, there were 1500 nits brightness in the white field and 18.2 nits in the dark area, giving a contrast ratio of 82.4:1. The competing screen alongside the
Supernova screen measured 750 nits in the white field and 52.3 nits in the dark field, giving a contrast ratio of just 14.3:1.
