A rear projection screen is a type of screen which is designed to be used with rear projection presentations. In rear projection, the image passes through the screen to the eyes of the viewer, rather than being reflected against the front of the screen. There are some definite advantages and disadvantages to using rear projection for image displays. When a rear projection screen is used, the projector is mounted behind the screen. In rear projection, the light intensity generally needs to be quite high, as the light must pass clearly through the screen.

One of the big advantages to rear projection is that the lights in the room can be on when images are projected, and viewers will still be able to see clearly. This can be useful in presentations, where people may want to take notes or engage with the speaker, which can be hard to do when the lights are off.

It is also necessary to have ample space behind a rear projection screen for the projector. The projector cannot be butted directly up against the screen, especially in the case of a large screen, and this can cause space problems in a venue with limited working room.
