Abstract:
1. A folding electronic apparatus, comprising a body and a cover, with a keyboard being disposed on the body and a capacitive touch screen being disposed on the cover, wherein a plurality of physically separate, spaced apart metal detection points are disposed on the body; and a sensor connected to the capacitive touch screen on the cover determines open and closed modes of the folding electronic apparatus according to the sensed change of a capacitance value resulting from the capacitive effect between the plurality of metal detection points and the capacitive touch screen, wherein when the folding electronic apparatus is closed, the plurality of metal detection points are close to the cover, the capacitance value resulting from the capacitive effect between a first predefined number of metal detection points and the capacitive touch screen changes, and the sensor senses that the capacitance value between the first predefined number of metal detection points and the capacitive touch screen changes, and determines that the folding electronic apparatus is in a closed mode; wherein when the folding electronic apparatus is open, the plurality of metal detection points are away from the cover, the capacitance value resulting from the capacitive effect between a second predefined number of metal detection points and the capacitive touch screen changes, and the sensor senses that the capacitance value between the second predefined number of metal detection points and the capacitive touch screen changes, and determines that the folding electronic apparatus is in an open mode; wherein the first predefined number is greater than the second predefined number; wherein the first predefined number defines a range, and the upper limit of the range is equal to the number of the metal detection points; and wherein the second predefined number defines a range, and the lower limit of the range is zero.
