  • Patent number: 4652932
    Abstract: A television receiver employs a liquid crystal display panel mounted in a unit which can be set into either a closed position in which the display panel is disposed within a recessed portion of the case of the television set, and an opened position in which ambient light passes through the display panel to be reflected from a mirror towards the viewer. In conjunction with this arrangement, operating control members are positioned to facilitate one-hand operation of the receiver, and the largest circuit components and batteries are positioned with respect to the display panel and control members such as to minimize the overall size of the receiver.
