  • Patent number: 8923934
    Abstract: A dual display folder type terminal having a hinge includes a manipulation unit formed in the hinge, wherein the inventive implementation of the hinge provides various function commands without the need of an additional space in the terminal. As a result, the size of the terminal doesn't suffer when implementing the manipulation unit. Further, the dual display folder type terminal can operate different modes based on the opening angle of a folder relative to the other folder.
