Abstract
The present invention provides an active matrix organic light-emitting diode display substrate and a display device. The active matrix organic light-emitting diode display substrate comprises a substrate and a plurality of pixel structures arranged in a matrix on the substrate, and further comprises a power signal structure for providing a power signal to each pixel structure, wherein the power signal structure comprises one layer of power signal electrode having a planar structure. By designing the power signal structure to include a power signal electrode having a planar structure, resistance of the power signal structure is reduced, and accordingly voltage drop of VDD decreases, thus the difference in driving voltage among organic light-emitting diodes is relatively small, and uniformity of display brightness of a display panel is ensured.
