ABSTRACT:
A rear-project video assembly with a foldable reflector includes a housing and a screen mounted in a first side of the housing. A reflector has one side pivotally connected to a second side of the housing for reflecting image to the screen. An overhead projector is mounted on a bottom of the housing for projecting image to the reflector and a drive device is mounted between the screen and the reflector for expanding the reflector when using the reflector and backward moving the reflector after using the reflector to reduce the volume of the rear-project video assembly. A bellows is mounted between the peripheries of the second side of the housing and the reflector to prevent the foreign matter and the light ray from entering the housing.
