An active matrix electroluminescence light emitting display, such as active matrix organic light emitting display, including an active matrix electroluminescence display panel and a power supply circuit is provided. The active matrix electroluminescence display panel includes a pixel array and an electrode for driving the pixel array. The electrode includes a first and a second electric connecting node. The power supply circuit includes a feedback circuit, a power system, a power input line and a regulating reference line. The power system includes a feedback end and an output end. The power system outputs a bias voltage according to a feedback voltage. The power input line has one end electrically connected with the first connecting electric node and another end used for receiving the bias voltage. The regulating reference line has one end electrically connected with the second electric connecting node and another end used for outputting the feedback voltage.
