摘要:
A portable terminal comprises a first body 104 on which the first display surface 102 is formed, a second body 108 on which the second display surface 106 is formed, and hinge units which combine the first body 104 and the second body 108 in a foldable way. The first display surface 102 and the second display surface 106 form a combined display 112 continuously at a time of opening the first body 104 and the second body 108, and it further comprises a display control unit which displays one information on the whole combined display 112. Two display screens respectively formed in the individual bodies are used effectively.
