Abstract:
The present invention relates to a touch panel. A capacitive touch panel, in which a location of a touch is sensed based on a variation in capacitance which is generated in an electrode upon a touch, includes one or more electrodes each configured to have an uniform resistance component in one direction on a substrate, and to pass a reference signal therethrough from a first side portion thereof to a second side portion thereof; and a location detection unit configured to apply the reference signal to the first side portion of the electrode, to receive a reference signal, altered by a resistance and a capacitance formed in the electrode upon a touch while passing through the electrode, via the second side portion of the electrode, and to determine a location of the touch by comparing the reference signal and the received altered reference signal.
