Abstract: A display panel, a motherboard, and a mini LED display device. The display panel includes: a panel edge extending along a first direction, and a display region and a test region. The test region is between the display region and the panel edge and includes test pads. At least two test pads are arranged along the first direction, adjacent ones of which are spaced by at least two first electrostatic discharge protection wires extending from one side of the display region adjacent to the test region to the panel edge. Each first electrostatic discharge protection wire includes a first line segment located between two adjacent test pads and a second line segment adjacent to the panel edge. A distance between adjacent first line segments between two adjacent test pads in the first direction is less than a distance between adjacent second line segments in the first direction.

Abstract: An antenna and its fabrication method, and a display device are provided. The antenna includes a substrate, a radiation electrode, a first dummy electrode, and a feed line. The radiation electrode, the first dummy electrode, and the feed line are disposed on the substrate. The feed line is coupled and connected to the radiation electrode. The first dummy electrode and the radiation electrode are adjacent but not connected to each other. Along a first direction, an orthographic projection of the radiation electrode to a plane where the substrate is located is a first projection, and an orthographic projection of the first dummy electrode to the plane where the substrate is located is a second projection. There is a first interval between the first projection and the second projection; and the first direction is perpendicular to the plane where the substrate is located.

Abstract: A touch-control display panel, driving method, and a touch-control display device are provided. The touch-control display panel includes: a display area including a plurality of pixels; a non-display area; a first substrate; and a second substrate opposing the first substrate. A portion of the first substrate in the first region includes a pixel electrode layer and a first electrode layer. The first electrode layer is located on a side of the pixel electrode layer away from the second substrate and includes a plurality of first electrodes. The pixel electrode layer includes a plurality of pixel electrodes. A touch-control electrode layer is located on a side of the second substrate toward the first substrate and includes a plurality of touch-control electrodes. Along a direction perpendicular to the touch-control display panel, each touch-control electrode of the plurality of the touch-control electrode overlaps with and connects with one or more first electrode of the plurality of the first electrodes.
