Abstract: An AMOLED comprises a plurality of pixel structures arranged in a matrix and one layer of power supply signal electrode configured to provide a power supply voltage signal for the pixel structures, and the power supply signal electrode has a planar structure. The planar power supply signal electrode can greatly reduce its resistance and hence can reduce the IR drop of power supply voltage signals that are transmitted over the power supply signal electrode, effectively reduce the impact of the IR drop on the display effect, and remarkably reduce the power consumption of a panel.
