An AMOLED display panel is provided. The AMOLED display panel includes a plurality of pixel structures arranged in a matrix and a plurality of power lines, configured to provide a driving power to the pixel structures, wherein two adjacent rows or two adjacent columns of the pixel structures is a period unit, each period unit is disposed corresponding to one of the power lines, the one of the power lines is disposed between the two adjacent rows or the two adjacent columns of the pixel structures, and the one of the power lines provides the driving power to the two adjacent rows or the two adjacent columns of the pixel structures disposed at two side of the one of the power lines. By practice of the disclosure, the amount of the power lines could be decreased, so high PPI (Pixels Per Inch) of the display panel could be achieved.
