Abstract
Disclosed is a method for precisely judging the number of touches. The method includes a step A of reading a touch sensing signal sensed by an iinfrared ray sensor module located at an icorner (i being a natural number not exceeding 3) of a touch panel, a step B of defining a portion of the touch sensing signal having a signal intensity lower than a predetermined touch recognition threshold signal as a touch recognition signal corresponding to the touches, and a step C of, when the touch recognition signal is recognized as representing one touch and the length of the overall section of the touch recognition signal is within a critical range as a result of analysis of the touch recognition signal, finally judging whether or not the touch recognition signal is recognized as one touch or two touches through re-analysis of the touch recognition signal.
