Abstract: An electronic device, a display panel, and a method for manufacturing the display panel are provided. The display panel includes a substrate, and data fan-out lines and a power supply fan-out line arranged in a step region of the substrate. An orthographic projection of an overlapping region between the power supply fan-out line and the encapsulating region on the substrate is non-overlapping with an orthographic projection of an overlapping region between each of the data fan-out lines and the encapsulating region on the substrate, thereby reducing the encapsulating failure of the sealant due to a common overlapping region of the to data fan-out lines and the power supply fan-out line in the encapsulating region, and improving the reliability of the display panel.

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.

Abstract: The present disclosure discloses a display panel, a manufacturing method thereof and a display device. By arranging positions of first transmission pads and second transmission pads, and setting areas of first film layers in the first transmission pads to be less than those of second film layers, when the first transmission pads and the second transmission pads are disposed oppositely, fully-opened openings are formed between the two pads, so that it is convenient to fill spaces between the first transmission pads and the second transmission pads with conductive components to allow the first transmission pads be electrically connected with the second transmission pads through the conductive components, guaranteeing an effective electrical connection between the first transmission pads and the second transmission pads and then ensuring signal transmission via first wires and second wires through the first transmission pads and the second transmission pads.
