An apparatus for testing an organic electroluminescent display panel having a plurality of data and scan lines comprises a detecting control circuit, a gate de-multiplexer and a source de-multiplexer. The detecting control circuit generates a gate test signal and a source test signal respectively to the gate de-multiplexer and the source de-multiplexer according to the position coordinate of a testing pixel in the organic electroluminescent display panel. The gate de-multiplexer and the source de-multiplexer send a gate testing voltage and a source testing voltage to one of the scan lines and one of the data lines respectively according to the gate and source test signals. In addition, the detecting control circuit further records an output voltage of the testing pixel.
