Abstract
Abstract A composite display is provided having display panels which move into and out of a viewing position. While in the viewing position the display panels form a concatenated display screen. The display panels are stored within a display housing with respective viewing areas being at least partially overlapped to reduce storage space. The display panels automatically move out of the storage position into the viewing position in a notebook computer configuration when opening the computer. Similarly, the display panels automatically move into the storage position when closing the computer. The display unit includes a post. A system unit includes a cam. The cam defines a track within which the post moves. While the display unit rotates from the closed position to the open position the post moves along the track causing a display to move into its viewing position.
