Touch sensing device and image display device using the same
A touch sensing device and an image display device using the same are discussed. The touch sensing can include touch sensors included in an image display panel, a touch sensing circuit unit configured to supply a driving signal to the touch sensors, receive a touch voltage from the touch sensors and generate sensing data based on a touch sensing result of the image display panel, and a micro control unit configured to determine whether or not the plurality of touch sensors, the touch sensing circuit unit and a self-stored firmware operate normally when a power source of the touch sensing device is turned on, and allow a touch sensing operation to be operated normally or delay a reset operation in a predetermined period unit and repeatedly perform the reset operation in a predetermined delay period unit based on a result of previous determination.
