AMOLED panel test circuit
The invention relates to the field of electronic circuit design technology, more particularly, to an AMOLED panel test circuit, by integrating the second test unit, the first test unit and the data line output unit together, and respectively achieves the test of the first test unit and the second test unit of the panel through switching on and off the transistor, avoids the problem that one of the test circuit needs to pass around the end of the panel because the test circuit is not integrated in prior art, which causes big line impedance, and increases the detection rate, and saves the cost.
