  • Publication number: 20120092291
    Abstract: The present invention relates to a resistive touchscreen for recognizing touch coordinates through a capacitor charging time constant, and more specifically, the invention comprises: an equal resistance line operating means for obtaining the same resistance line according to an (Rv+Ry+) value and the same resistance line according to an (Rv+Ry?) value by using the charge time constant after a charge time constant measuring means measures charge time constants of capacitors CconL and CconR; and a coordinate calculating means for obtaining intersecting points of the resistance lines, thereby perceiving the intersecting points as touch positions. According to the present invention, a conventional ADC (analog to digital converter) is not used because the touch positions can be perceived through the capacitor charging time constants, whereby the invention is advantageous for IC integration.
