How to choose the right projection screen

Screen plays a very important role for a slide show system, especially the home cinema system. Ultimate image quality that we observed was the decision by the projection screen. You can spend many thousands of dollars to purchase a projector. But all will not be promoted if the final image to be expressed by a poor quality screen. Can not underestimate its contribution in a sub-standard cinema systems.

Select Types of Screen
If your projection application is permanent, wall and ceiling screens are the best choice.

Decide on screen location
To get the best effect, it is important is to choose an optimal position for the screen. For meeting or conference rooms, it is recommended to not place the screen on the same side as the entrance as it may draw attention away from the audience when someone enters the room during the meeting. Secondly, the projection screen not only reflects the projected images but also the external light (ambient light), therefore any windows or electrical lamps should be positioned to minimize the influence of external light in order to get the best effect.

The projector is to project the images from the same side as the entrance and with no obstacles between the projector and the screen. It can be conducted smoothly without disruption.

The screen is placed on the same side as the entrance. This will cause interruption to the meeting when someone enters the room.

The external lights will be reflected as well. The relative position between the screen and windows is a determining factor in considering screen location.
Ensure good viewing angle
Projection screen with higher gain then more narrow viewing angle. The reason is because the high gain screen will reflect light in the direction opposite the source of light, as well as a mirror, instead of scattered light are off the side.

For the standard white screens, brightness decline also occurred on both sides of the screen, especially the large projection screen. To remedy this, the cinema used curved screen to reflect light more toward the audience. Typically the depth of the curved screen by 5% of the screen width. For example, the 20m wide screen 1m deep.

Determine the screen material surface
If the screen will be used for multiple types of projections, choose the screen surface that meets the requirements of the lesser performing projection method.
