  • Patent number: 11983368
    Abstract: A display panel and a touch display device are disclosed. The display panel includes a first touch electrode positioned in the first area, a second touch electrode positioned in the second area, a third touch electrode positioned in the third area, a fourth touch electrode positioned in the fourth area, and a first connection pattern electrically connecting the first touch electrode and the second touch electrode. A connection portion between the third touch electrode and the fourth touch electrode may pass through an intermediate area between the first area and the second area. The first connection pattern may pass through the intermediate area between the first area and the second area and may cross the connection portion between the third and fourth touch electrodes. Each of the first, second, third and fourth touch electrodes may include a first metal layer and a second metal layer, the first metal layer and the second metal layer may be separated by a touch-interlayer insulating layer.

  • Patent number: 11194436
    Abstract: Provided is a touch display device having a hole provided in an active area. Touch electrodes are disposed in at least a portion of the active area, in which the hole is provided and no images are displayed. The touch electrodes disposed in surrounding areas of the hole are easily connected. In a case in which a plurality of holes are disposed in the active area, a structure disposed in the area between the holes to increase the number of the touch electrode connecting lines is provided. This structure increases capacitance-generating areas between the intersecting touch electrode lines, thereby improving the performance of touch sensing in the area between the holes.

  • Patent number: 10860124
    Abstract: The electroluminescence display device and the method of manufacturing the same are disclosed. The electroluminescence display device may include an on-cell type touch screen panel and a flexible printed circuit (FPC) for slimming down and cost reduction. It is possible to suppress cracks from being generated in the pad portion of the touch screen panel during film on glass (FOG) bonding by arranging the lower layer of the FPC at a certain distance away from the end of the touch screen panel.
