People see a lot of movies every weeks later to understand that investing in one of these screens for home use will be less costly in the long term, but also evening meetings film.

It is a lot of issues involving technology and design techniques involved in the formulation of the screen shows better. Basically, the surface is generally used heavy white vinyl. However, one of the most important factors that must be submitted for consideration is the index refractory projector screen used in the manufacture of the outer surface of the screen. the exact amount of light a special screen material projector may reflect mainly determines the quality and cost. The surface must be balanced in terms of reflection that provides superlative resolution.
Basically, materials used for the manufacture of surfaces can be divided into four main types: white matte pearl, silver and glass beads. white matte surface that essentially reflects 5% of the light that is subject to, and therefore transmit the image of the screen is very bright. In addition, pearlescent screens according to an index of reflectivity total of about 15%, which is also one of the best materials around the projector screen.

Similarly, the issue based silver screens provide 30% reflectivity and why the image seems a bit brighter than normal. Colors like black appears as a medium gray and dark colors seem like a little boring. Finally, glass beads is another material used for making these screens. This type of surface materials to the results that have the most high reflectivity with respect to the light and the projected image appears to be very bright. surfaces glass beads are used in ordinary circumstances of projections that require special conditions.
In essence, pearl or silver surfaces can be made adding a further reflection of white vinyl enamel, while a glass bead screen consists of a large amount of molten glass beads minute.
