Is the production getting complicated with all the scaffolding, rain-shelters, media-servers, cable and security works?
The screen also has hundreds of small, evenly spaced holes to allow air to and from the speakers and subwoofer, which often are directly behind it.
Rigid wall-mounted screens maintain their geometry perfectly just like the big movie screens, which makes them suitable for applications that demand exact reproduction of image geometry. Such screens are often used in home theatersalong with the pull-down screens.
An overhead projector projecting onto a pull-down screen Pull-down screens also known as manual wall screens are often used in spaces where a permanently installed screen would require too much space. These commonly use painted fabric that is rolled in the screen case when not Projection screen paint, making them less obtrusive when the screen is not in use.
Fixed-frame screens provide the greatest level of uniform tension on the screens surface, resulting in the optimal image quality.
They are often used in home theater and professional environments where the screen does not need to be recessed into the case. Electric screens can be wall mounted, ceiling mounted or ceiling recessed. These are often larger screens, though electric screens are available for home theater use as well.
Electric screens are similar to pull-down screens, but instead of the screen being pulled down manually, an electric motor raises and lowers the screen.
Electric screens are usually raised or lowered using either a remote control or wall-mounted switch, although some projectors are equipped with an interface that connects to the screen and automatically lowers Projection screen paint screen when the projector is switched on and raises it when the projector is switched off.
Switchable projection screens can be switched between opaque and clear. In the opaque state, projected image on the screen can be viewed from both sides. It is very good for advertising on store windows.
Inflatable movie screen Mobile screens usually use either a pull-down screen on a free stand, or pull up from a weighted base. These can be used when it is impossible or impractical to mount the screen to a wall or a ceiling.
Both mobile and permanently installed pull-down screens may be of tensioned or not tensioned variety. Tensioned models attempt to keep the fabric flat and immobile, whereas the not tensioned models have the fabric of the screen hanging freely from their support structures.
In the latter screens the fabric can rarely stay immobile if there are currents of air in the room, giving imperfections to the projected image. These include non-solid screens, inflatable screens and others. See the respective articles for more information.
Screen gain[ edit ] One of the most often quoted properties in a home theater screen is the gain. This is a measure of reflectivity of light compared to a screen coated with magnesium carbonate titanium dioxide or barium sulfate  when the measurement is taken for light targeted and reflected perpendicular to the screen.
Titanium dioxide is a bright white colour, but greater gains can be accomplished with materials that reflect more of the light parallel to projection axis and less off-axis. Frequently quoted gain levels of various materials range from 0.
Very high gain levels could be attained simply by using a mirror surface, although the audience would then just see a reflection of the projector, defeating the purpose of using a screen. This is possible because humans have greater sensitivity to contrast in smaller details, but less so in luminosity variations as great as half of the screen.
Other screens with higher gain are semi-retroreflective. Unlike mirrors, retroreflective surfaces reflect light back toward the source. Hot spotting is less of a problem with retroreflective high gain screens. Unfortunately, at the perpendicular direction used for gain measurement, mirror reflection and retroreflection are indistinguishable, and this has sown confusion about the behavior of high gain screens.
A second common confusion about screen gain arises for grey colored screens. If a screen material looks grey on casual examination then its total reflectance is much less than 1.
However, the grey screen can have measured gain of 1 or even much greater than 1. The geometric behavior of a grey screen is different from that of a white screen of identical gain. Therefore, since geometry is important in screen applications, screen materials should be at least specified by their gain and their total reflectance.
Instead of total reflectance, "geometric gain" equal to the gain divided by the total reflectance can be the second specification. Curved screens can be made highly reflective without introducing any visible hot spots, if the curvature of the screen, placement of the projector and the seating arrangement are designed correctly.
The object of this design is to have the screen reflect the projected light back to the audience, effectively making the entire screen a giant "hot spot".ChromaFlux ScreenPaint5DS2 - Sprayed is a water-based projection screen paint for 2D and 3D applications.
