Claim:
1. An active matrix organic light-emitting display (AMOLED), comprising: a plurality of pixel structures arranged in a matrix, wherein each of the pixel structures comprises an upper substrate, a lower substrate and a buffer layer, a thin-film transistor (TFT) structure and an organic electroluminescent (EL) structure disposed on the lower substrate in order, and the TFT structure is configured to control the organic EL structure; and one layer of power supply signal electrode configured to provide a power supply voltage signal for the pixel structures, wherein the power supply signal electrode having a planar structure and is electrically connected with an active layer of the thin film transistor; wherein the power supply signal electrode is disposed between the buffer layer and the lower substrate, and the pixel structure is of a bottom emission type, in which case a pattern in which the power supply signal electrode is removed in an area of the power supply signal electrode is provided, corresponding to a light-emitting window of each pixel structure.
