    Abstract: A projection television includes a video projector for projecting a video image, electrical circuit for supplying a video signal to the video projector, and screen on which the video image projected from the video projector is formed. At least the screen is arranged in a first housing and at least the video projector is arranged in a second housing. The projection television is adapted to be disassembled either into two separate housings or into one overall assembly where a housing of a smaller volume of the two housings is completely accommodated within a housing of a larger volume. The second housing may be pivotally coupled to the first housing so that the second housing pivots out of the first housing to a first position to project the video image onto the screen when assembled for viewing, and into the first housing to a second position to be completely accommodated in the first housing.
