Field
Exemplary embodiments relate to a display device, and, more particularly, to a display device integrated with a touch sensor.
Discussion of the Background
A touch sensor, which allows a user to input information by contacting a screen using a finger, a pen, etc., may be applied as an input device of a display device. Among various sensing types of the touch sensor, a capacitive type utilizes two electrodes spaced apart from each other, to sense a position where the capacitance has changed from a contact.
To implement a flexible display device, a display device may be formed to have a thin thickness. To this end, a touch sensor may be integrated into a display device. An on-cell type touch sensor may not include a substrate for the touch sensor, and, thus a sensing electrode may be directly formed on any one component of the display device.
A touch driving unit controls an operation of the touch sensor. The touch driving unit may transmit a sensing input signal to the touch sensor, or may receive a sensing output signal to process it. The touch driving unit may process the sensing output signal to generate touch information, such as the occurrence of a touch, a touch position, and the like. The touch driving unit may be disposed on a separate printed circuit board (PCB), and may be connected to a touch pad portion. However, in the touch pad portion, a portion of touch wires connected to the touch electrodes may be exposed. When the touch wires are exposed to the outside, corrosion may occur on the touch wires from moisture and the like.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept, and, therefore, it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.
