Abstract
The present embodiment may provide a touch sensing circuit including: an analog signal processing circuit including one or more adjustable filters configured to receive a touch sensing signal from a touch electrode of a panel and to transmit some of a frequency region of the touch sensing signal; and a touch control circuit configured to determine a change in capacitance of the touch electrode attributable to an object approaching the panel and to transmit a controlling signal to control the adjustable filters of the analog signal processing circuit. The adjustable filter of the present embodiment may include a variable resistor or a variable capacitor. A resistance value or capacitance value of the adjustable filter may be changed in response to the controlling signal, thus changing a frequency pass band of the touch sensing signal.
