1. A method of testing an organic light emitting diode array, which has a plurality of pixel units and each of the pixel units comprises a commonly shared power supply line and a commonly shared common line, the method comprising the steps of:

  • providing a current meter and a voltage source connected in series between the common line and power supply line;

    sequentially writing a first logic value to the pixel units and taking first current readings corresponding to the written pixel units by virtue of the current meter;

    determining whether the pixel units are defective according to the first current readings corresponding to the written pixel units.
