Abstract
An organic light-emitting diode (OLED) contact impedance testing device includes an organic light-emitting diode cathode material layer located in an organic light-emitting diode panel. A plurality of test points is located on an edge of the organic light-emitting diode panel. A plurality of connecting lines connects the organic light-emitting diode cathode material layer to the test points. Each test point is partially superimposed by one of the connecting lines. Each connecting line is partially superimposed by the organic light-emitting diode cathode material layer. The OLED contact impedance testing device can rapidly detect the contact impedances of different components in the OLED panel. Thus, problems in the complicated OLED panel can rapidly be located through measurement of the impedances.
