    摘要： 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 ith infrared ray sensor module located at an ith corner (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.

    摘要： A touch panel display device includes a liquid crystal panel to display an image by regulating transmittance of light supplied from a back light unit, and a touch sensing part provided on upper edges of the liquid crystal panel in order to detect a position touched by a user or an object. The touch sensing part includes infrared lamps to generate and emit infrared light, infrared light reflecting tubes mounted with the infrared lamps, and image sensors to sense the infrared light output from the light output regions of the infrared light reflecting tubes. Each of the infrared light reflecting tubes has light output regions and non-output regions evenly formed at a surface facing an upper surface of the liquid crystal panel so that the infrared light emitted from the infrared lamps is evenly irradiated on the upper surface of the liquid crystal panel.
