AMOLED pixel driving circuit and pixel driving method

The invention provides an AMOLED pixel driving circuit and a pixel driving method. The AMOLED pixel driving circuit comprises an inner pixel circuit and an outer compensation circuit. The inner pixel circuit is provided with at least one sub-pixel circuit, which is provided with a first driving thin film transistor (T1 1, T1 2.. T1 N), a second switch thin film transistor (T2 1, T2 2.. T 2N), an inner capacitor (C1 1, C 1 2.. C1 N), and an organic light-emitting diode (OLE). The outer compensation circuit is provided with a third switch thin film transistor (T3), a fourth switch thin film transistor (T4), a fifth switch thin film transistor (T5), a sixth switch thin film transistor (T6), and an outer capacitor (C2). The single or sub-pixel circuit of the inner pixel circuit adopts a 2T1C circuit structure, and the outer compensation circuit is used to compensate the non-uniformity and the drifting of the threshold voltage of the driving thin film transistor, and therefore the long-term uniform light emission of the AMOLED is realized, the power consumption is reduced, and the resolution ratio is increased.
