Projection Screens and Their Common Types

Whether for entertainment, education, or other purposes, projection screens are quite useful for displaying projected images for an audience. Projection screen equipment may be portable or permanent in installation, while others may even take advantage of inflatable screens for outdoor events. The screen that is used for projection will often differ depending on the application and environment, materials and designs being set to enhance how light is diffusely reflected.
For projection screens that are used for movie theaters, reflective screens are used, such materials either being aluminized or a white surface containing small glass beads. As projection screen accessories such as speakers and subwoofers are placed directly behind the assembly, evenly spaced holes are situated across the screen itself. Home theaters are fairly similar in geometry, often coming in the form of rigid wall-mounted screens or pull-down screens. Pull-down screens are quite beneficial for spaces where there is not enough space for a permanent installation, and such equipment is commonly produced with painted fabric.
In some instances, an electric screen may be used. These types are often situated on a wall, ceiling, or recessed within a ceiling. While typically being large in size, some may be available for home theater use. Often, these screens are raised and lowered with the use of electric motors that are controlled by a remote control or wall-mounted switch. Sometimes, the electric screen may even be automatic in deployment and retraction, operating when the projector itself is turned on or off.
Beyond such types, another common variation is the mobile screen. Generally, such equipment will come in the form of a pull-down screen placed on a free stand or a pull-up screen placed on a weighted base. Typically, such options are best when there is no wall or ceiling that the projector can feasibly be attached to. Alongside permanently installed pull-down screens, both types may either be tensioned or not tensioned. Non-tensioned screens often face the downside of constant movement if there is a current present, causing the image to be imperfect.
As visuals are simply projected onto the screen, rather than sourcing from the screen itself, as would be the case with a TV, image brightness and contrast will be dependent on ambient light conditions, the luminous power of the project, and the size of the projected image itself. Often, the larger a screen is, the less luminous the image will be when there is ambient light. To promote a clearer and higher quality image, the room should be kept as dark as possible. Furthermore, screen surfaces that direct light back at the source can also be beneficial. 
If a flat screen with high reflection is used, such equipment may suffer from hot spots where a brighter image is displayed in one area. High gain screens also suffer from a reduced viewing angle, meaning that one needs to be very selective on which screen they choose and where it will be placed.
