LOCATION DETECTION DEVICE AND METHOD FOR CONTROLLING SAME, AND SYSTEM COMPRISING SAME

摘要

An electrostatic capacitance-type touch panel (10) comprises, for example: a substrate (12) having a conductive film (14) formed on the surface thereof; nodes (A) and (B) on the X-axis of the conductive film (14), and nodes (A) and (D) on the Y-axis thereof; a reference clock generating circuit (20) for applying a clock signal to the nodes (A-D) by way of corresponding load resistors (R0); a location information extraction unit (30) for generating a differential voltage signal between the nodes (A) and (B), and between the nodes (A) and (D), for example; and a location detection unit (40) for detecting the X-axis and Y-axis coordinates on the basis of the location information generated.
