Abstract
An image display system may include a host device, a touch-sensing device connected to the host device, and a display device connected to the host device. A method of operating the image display system may include the following steps: determining, using the host device, a required-touch quantity; selecting, using at least one of the host device and the touch-sensing device, a designated area based on the required-touch quantity, wherein the designated area corresponds to a plurality of designated driving electrodes that is a subset of driving electrodes of the touch-sensing device; detecting, using the designated driving electrodes without using other driving electrodes of the touch-sensing device, touch input provided in the designated area; and responding to the touch input using at least one of the host device and the display device.
