Abstract: An OLED device includes a substrate including a display region including a pixel region and a peripheral region surrounding the pixel region. A pad region is spaced apart from the display region, and a bending region is disposed between the display region and the pad region. A plurality of pixel structures are disposed in the pixel region on the substrate. A touch screen structure is disposed on the pixel structures. A plurality of touch screen wirings are disposed in the bending region on the substrate. The touch screen wirings are electrically connected the touch screen structure. A connection structure is in the pad region. The connection structure electrically connects touch screen wirings to each other. A same touch sensing signal is applied to touch screen wirings that are connected to each other.

Abstract: A display device may include a display panel and an input sensor. Mesh lines of the input sensor may include first mesh lines extending in a first direction and second mesh lines extending in a second direction crossing the first direction. The first mesh lines and the second mesh lines may cross each other at a plurality of cross points. In a unit region of the sensing electrode, first cutting points may be defined in the first mesh lines and the second mesh lines, and second cutting points may be defined in the first mesh lines and the second mesh lines.
