BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the present disclosure relate to a touch panel and a touch device.

2. Description of the Related Art

As society develops into an information society, demand for a display device for displaying images is increasing, and various types of display devices such as a liquid crystal display device, a plasma display device, and an organic light-emitting display device are being utilized. In order to provide more various functions to a user, such display devices provide functions of recognizing a user's touch on a display panel and performing an input process based on the recognized touch.

For example, by disposing a touch sensor on a display panel and sensing a change in capacitance caused by a user's touch on the display panel, the presence or absence of the user's touch and a touch position on the display panel can be sensed. In addition, methods of sensing a change in capacitance by sensing a touch include a method of applying touch driving signals having the same voltage level to respective touch sensors and sensing a change in self-capacitance caused by a touch, and a method of applying touch driving signals having different voltage levels to adjacent touch sensors and sensing a change in mutual capacitance generated at the time of touch.

Here, in the method of sensing the change in mutual capacitance, a phenomenon may occur in which an electric field is formed between adjacent touch sensors and charges are concentrated to a portion where the electric field is formed. As the charges are concentrated, the repulsive force between the touch sensors in a specific area increases.

Thus, the touch sensors may be damaged in the portion where the repulsive force between the touch sensors increases as described above, and in that, due to the damage of the touch sensors, a touch driving signal may not be transmitted or touch sensing may not be performed in a specific region.
