Consistently white or grey screens are used just about exclusively as to keep away from any discoloration to the image, while the mainly preferred brightness of the screen depends on a number of variables, such as the ambient light level and the luminous power of the image basis.

Flat or warped screens may be used depending on the optics used to project the representation and the desired geometrical accurateness of the image production, flat screens being the more familiar of the two. Screens can be additional planned for front or back projection, the more frequent front projection systems having the representation source positioned on the same side of the screen as the audience.

Dissimilar markets survive for screens targeted for make use of with digital projectors, movie projectors, overhead projectors and slide projectors, even though the basic plan for each of them is very much the same: front projection screens effort on diffusely reflecting the light projected on to them, whereas back projection screens work by diffusely send out the light throughout them.

Certain screens are intended to selectively reproduce the narrow wavelengths of projector light at the same time as absorbing other wavelengths in the visual spectrum. One screen prepared by Sony, which appears grey when viewed in common room light, is designed to decrease the consequence of ambient light.

This works by preferentially engrossing ambient light of colors not used by the projector, at the same time as preferentially dazzling the colors of red, green and blue light the projector uses. A contrast-enhancing screen has been established by Dai Nippon Printing (DNP) and Screen Innovations which is foundation on thin layers of black louvers rather than wavelength-selective reflection properties.
