METHOD FOR PREVENTING MALFUNCTIONS DUE TO EXTERNAL ENVIRONMENT CHANGE IN A TOUCH DETECTION METHOD OF MATRIX COMPOSITION, FOR PREVENTING THE MALFUNCTION OF A TOUCH SENSOR SWITCH AND NEIGHBORING SENSORS

摘要

PURPOSE: A method for preventing malfunction due to external environment change in a touch detection method of matrix composition is provided to prevent the malfunction of a touch sensor switch and neighboring sensors.;CONSTITUTION: A matrix type touch sensor switch includes a plurality of touch sensors. A time division switch detects the touch sensor in the touch sensor switch. Oscillators A and B(20,30) are connected with the time division switch. The oscillators A and B generate detection/reference clocks. A divider(40) sets reference time. Through the detection/reference clocks, a decision unit(50) decide touch sensing.;COPYRIGHT KIPO 2010
