METHOD AND DEVICE FOR DRIVING MULTI-TOUCH PANEL, AND MULTI-TOUCH PANEL DEVICE USING THE SAME

摘要

PURPOSE: A method and a device for driving a multi-touch panel, and a multi-touch panel device using the same are provided to continuously use the touch panel by precisely recognizing a touch position in case that the touch panel is damaged, and offer a 3-dimensional effect to a character displayed on the touch panel by using a z-axis value except an x and y-axis value. CONSTITUTION: The first and the second ADC(Analog Digital Converter)(58,60) respective receive/convert an analog signal detected from the first and the second touch panel(54,56). A comparator(62) outputs a signal representing the identity between the signals by comparing the signal output from the first and the second ADC. A CPU(64) calculates a coordinates value based on the signal output from the first and the second ADC depending on the signal output from the comparator. To display an image matched with touch through a display device, the CPU outputs the coordinates value to a system.
