Title: METHOD FOR REMOVING NOISE INTRODUCED FROM NON-SENSING REGION IN TOUCH INPUT SENSING DEVICE
Abstract:
A touch input sensing device is disclosed, the device comprising: a sensing part having a touch sensing region including one or more touch nodes; a touch sensing signal output device for outputting information regarding touch inputs with respect to the one or more touch nodes; and a noise sensing electrode arranged on a non-sensing region that is formed between the sensing part and the touch sensing signal output device (30). A touch signal input port of the touch sensing signal output device is connected to wiring arranged on the non-sensing region, a noise signal input port of the touch sensing signal output device is connected to the noise sensing electrode and the touch sensing signal output device removes effects caused by noise introduced from the wiring, using a signal received from the noise sensing electrode.
