TOUCH SENSOR WITH RESISTIVE PATTERN FORMED IN ONE CONTINUOUS LINE, AND METHOD FOR SENSING TOUCH POINT USING TOUCH SENSOR

摘要

The present invention relates to a touch sensor. More specifically the invention concerns the touch sensor with a resistive pattern and a method for measuring coordinates of a touch point. The touch sensor according to the invention comprises: a lower substrate, a flexible upper sheet that is spaced a certain length from the upper plane of the lower substrate, plural spacers that are installed between the lower substrate and the flexible sheet, a resistive pattern where conductive materials are arranged in one continuous line on the upper plane of the lower substrate not to overlap, a conductive film that is arranged on the lower plane of the flexible sheet, and a pair of resistors that are connected with each other in serial at both ends of the resistive pattern. The invention enables the fabrication of a resistive touch sensor (screen) that has no opaque segments or dead zones caused by the electrode printing at the edge of the touch sensor. In addition, the touch sensor according to the invention senses a touch point as well as touch strength (touched area).
