Projektionsflade

Projektionsflade is a German term that translates to "projection surface" or "screen" in English. It refers to any surface onto which an image or light is projected. The most common examples are the screens used in cinemas, theaters, or for presentations with projectors. These surfaces are typically designed to be flat and smooth, and often have a reflective or diffuse coating to ensure a clear and uniform image.

The properties of a projektionsflade are crucial for the quality of the projected image. Factors such as reflectivity, gain, viewing angle, and color reproduction all play a role. Different types of projektionsflade exist, each suited for specific applications. For instance, a matte white screen is common for general use due to its wide viewing angles and good color accuracy. High-gain screens are used when a brighter image is needed, while perforated screens allow sound to pass through from behind. The size and aspect ratio of the projektionsflade are also important considerations, determined by the projector's capabilities and the intended viewing environment. In essence, the projektionsflade is the final destination for the light from a projector, transforming the invisible beam into a visible picture.
