Abstract: A light-emitting panel and a display device are provided. The light-emitting panel includes a base substrate, and a plurality of driving transistors and a plurality of light-emitting elements. One driving transistor is electrically connected to at least one light-emitting element. The plurality of light-emitting elements are arranged in an array to form one or more light-emitting element rows along a first direction and to form one or more light-emitting element columns along a second direction. In a direction parallel to a plane of the base substrate, the first direction intersects the second direction. In the direction parallel to the plane of the base substrate, a quantity of driving transistors adjacent to one light-emitting element is A, where A

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.
