  • Patent number: 10700142
    Abstract: The disclosure discloses an organic electroluminescent display panel and a display device. The display panel includes at least one touch sensing element located in a rounded corner display area of the display panel. An outline of the at least one touch sensing element includes an arc. The arc lies against an outline of the rounded corner of the rounded corner display area. In this way, difference between the outline of the touch pattern of the display panel and the outline of the abnormally shaped display panel can be minimized to reduce the size of parts of touch sensing element(s) going beyond the rounded corner display area that need to be cut off and integrity of the pattern of the touch sensing element(s) can be improved, thus improving quality of response signals and the touch performance at the abnormally shaped edge.
