摘要： A light-emitting substrate includes a substrate, a plurality of power supply lines disposed on the substrate, a plurality of light-emitting devices disposed on the substrate and a plurality of resistance lines disposed on the substrate. Each light-emitting device includes, in a direction perpendicular to the substrate, a first electrode and a second electrode that are disposed sequentially, and a light-emitting functional layer disposed between the first electrode and the second electrode. The first electrode is closer to the substrate than the second electrode. An end of each resistance line is coupled to a power supply line, and another end of each resistance line is coupled to a first electrode of a light-emitting device. Each resistance line and the first electrode coupled thereto are disposed in a same layer.

摘要： A display panel includes a display area (DA) and a peripheral area (PA) surrounding the display area (DA). The display area (DA) includes a second area and a first area that includes first pixel units disposed around holes, where the second area includes second pixel units and K data lines. The second pixel units include M columns*N rows of light emitting devices, M*N bottom drive circuits located at lower layers of the light emitting devices, and M*N anode leads connecting the light emitting devices to the bottom drive circuits. Intervals between some or all of the adjacent light emitting devices are greater than dimensions of the bottom drive circuits corresponding to the light emitting devices, and therefore there are gaps between the some or all of the second pixel units.
