Abstract
The embodiments of the present invention provide a folding electronic apparatus and a method for detecting open and closed modes thereof. The folding electronic apparatus includes a body and a cover, with a keyboard being disposed on the body and a capacitive touch screen being disposed on the cover. A plurality of metal detection points is disposed on the body. A sensor connected to the capacitive touch screen senses change of a capacitance value resulting from capacitive effect between the plurality of metal detection points and the capacitive touch screen, and determines open and closed modes of the folding electronic apparatus. The embodiments of the present invention detect open and closed modes of a folding electronic apparatus using a sensor connected to a capacitive touch screen by predefining a plurality of metal detection points on a keyboard or physical structure of the folding electronic apparatus.
