A touch-type display panel includes an array substrate including a plurality of sub-pixels defined by gate lines and data lines; a plurality of touch electrodes disposed to cover the sub-pixels; two or more touch driving lines that electrically connect a touch driving circuit to a respective one of the touch electrodes; and a connection line disposed on both sides of the one of the touch electrodes and configured to electrically connect the two or more touch driving lines.

Touch-type display panel and short-repair method thereof

There is provided a touch display device including a display panel including a first electrode for touch sensing, a first support that covers a back surface of an edge area of the display panel, a second support on a back side of the first support and that covers an entirety of the back surface of the display panel, and a touch driver configured to: apply a first electrode driving signal to the first electrode, select one of the first support and the second support as a second electrode, and apply a second electrode driving signal to sense a user's touch pressure applied to the display panel.

Touch display device having a gap between electrodes that is variable

A touch display device. A touch display panel includes a source multiplexer switching the transfer of source signals to data lines. In a low power wake-up gesture (LPWG) mode in which a touch input is only sensed in a state in which a display function is off to reduce power consumption, a source multiplexer control signal is provided to set the source multiplexer in an on state, in synchronization with a touch sensing section in which a touch driving signal is provided. This can discharge electric charges generated within the display panel, thereby preventing display defects due to the electric charges.
