HoloDark Rear Projection Film is an ultra-high contrast rear projection material. Not only are viewing angles not affected by this added contrast, but we also have higher ambient light rejection from the front and rear of the film. HoloDark Rear Projection Film is the latest in professional grade rear projection films, offering the highest contrast, light rejection and viewing angles of any rear projection film. HoloDark Film is available in large, seamless sizes up to 122-inch diagonally and in a choice of either 4:3 or 16:9 aspect ratios. Tiled installation allows for even larger digital displays. Create an instant rear projection display by applying HoloDark Film to any glass or acrylic surface. Built-in adhesives expedite the installation process.
