Types of roll down projector screens
A roll down projector screen is designed to roll down when in use and roll up for convenient storage. Variations include cases that are mounted in the ceiling and wall-mounted cases. The screens can be rolled down from the case for use. Some screens are autonomous and have to be mounted on a wall manually.
Roll-down projector screens are favored because they can be concealed and also tend to be unobtrusive. They also allow for great viewing experiences as they can offer large images. The screens can be retracted to save room sometimes, and the screens offer much better contrast and brightness than walls or ceilings.
Roll-down projector screens come in a variety of types, which can be classified based on how they are controlled or activated. These include manual, motorized, and rechargeable screens:
- Manual roll down screens: These are controlled manually, and the rollout and rolling back up is a physical task. A crank or pull-down tab usually operates the screens. The screens are beneficial for users who prefer a hands-on approach or do not mind rolling the screen back up. They are also less expensive than other options.
- Motorized screens: These screens are operated using a remote motor that rolls the screen either down or up. They are convenient because they allow for easy operation of the screens without having to do it physically. The screens are, however, more expensive than manual screens.
- Rechargeable screens: These screens are cordless and are usually powered by a rechargeable battery. Rechargeable screens offer the convenience of wireless operation while being powerful using rechargeable batteries instead of being plugged into a power source. They are less cluttered than other motorized screens that need to be plugged into a power source. The screens are, however, heavier because of the batteries and are generally more expensive.
Other categorization methods include classifying the screens based on what is controlling the rollup and rollout mechanism. Three main types are largely popular and used, which include a handheld remote, an electric switch, and a wired IN/OUT control:
- Handheld remote: A remote control that is usually in the form of a wand controls the rolling up or down of the screen. The wand controls the screen's movement through either RF (radio frequency) or IR (infrared) technology.
- Electric switch: An electric switch that resembles a light switch that can be toggled on or off controls some rollup screens. The electric switch operates the screen's movement through an electric motor.
- Wired IN/OUT control: This control system allows the user to use a wired IN/OUT control system to roll the screen up and down. The system is connected to a power source through a port that is either an AC outlet or a specific power port.
