Abstract

The present invention provides a notebook computer. The notebook computer includes a secondary display screen that has a small size and a primary display screen that has a large size. The secondary display screen may be a touch display screen and is operable for solely displaying an image and conducting an input/output operation so that when the operation life of the notebook computer get short, the large-sized primary display screen can be shut down for reducing energy consumption, while the secondary display screen may be powered by the notebook computer or may be provided with an individual battery to supply electrical power thereto and may establish communication through a contact type connector with a main board of the notebook computer or communicate with the main body of the notebook computer through wireless communication modules, so that the notebook computer may possesses extended operation life and is also operable in multiple operation modes that can be selected and set by a user so as to improve user'"'"'s experience and production competition power.
