Touch sensing device and image display device using the same

An image display device, comprising:

• an image display panel including a plurality of pixel arrays arranged thereon to display an image, the image display panel configured to sense a touch input through a plurality of touch sensors;
• a timing controller configured to control driving timings of gate and data drivers so that the image display panel displays an image;
• a touch sensing device configured to determine whether or not there is a touch sensing defect, delay a reset operation in a predetermined period unit and repeatedly perform the reset operation in a predetermined delay period unit when it is determined that there is a touch sensing defect, and drive a touch sensor of the image display panel and output touch coordinate information based on a touch sensing result when it is determined to be in a normal operation state;
• and
• a host system configured to supply image data and a plurality of timing signals to the timing controller, and execute an application program associated with touch coordinate information supplied from the touch sensing device.
