Abstract
The present invention discloses a distance sensing circuit and a touch-control electronic apparatus. The touch-control electronic apparatus includes a distance sensing circuit. The distance sensing circuit comprises a distance sensing unit, a capacitive sensing unit, and an operation unit. The distance sensing unit senses the distance between an object and the touch-control electronic apparatus and generates a first sensing signal. The capacitive sensing unit generates a second sensing signal corresponding to the object. The operation unit judges the distance between the touch-control electronic apparatus and the object according to the first and the second sensing signals. The touch-control electronic apparatus according to the present invention can truly judge the distance between itself and the object by means of the distance sensing unit and the capacitive sensing unit for controlling touch-control functions of the touch-control electronic apparatus.
