Image display systems are provided, in which a touch sensing circuit includes at least one voltage storing unit to generate a corresponding voltage when a capacitance variation caused by a touch event occurs. The voltage storing unit includes a first capacitor having a first terminal coupled to an alternating current (AC) common voltage from a common electrode and a second terminal coupled to a first node, a first switching element having a first terminal coupled to the second terminal of the first capacitor and a second terminal coupled to the AC common voltage, and a second switching element having a first terminal coupled to the second terminal of the first capacitor. |
