1. A method for sensing two or more touch inputs, the method comprising:
- receiving sensing signals of the touch inputs from plural sensing electrodes;
calculating a value dependent on a distance between the touch inputs based on the received sensing signals; and
determining the existence of the two or more touch inputs if the calculated value is more than or equal to a threshold value.

Abstract
A method for sensing two or more touch inputs includes receiving sensing signals of the touch inputs from plural sensing electrodes, calculating a value dependent on a distance between the touch inputs based on the received sensing signals, and determining the existence of the two or more touch inputs if the calculated value is more than or equal to a threshold value. The plural sensor electrodes include a pair of sensing electrodes that correspond to same coordinates on a first axis, and the sensing signals are received from the pair of sending electrodes along the first axis.
