A method for detecting a display panel

A method for detecting a display panel, the display panel includes an array substrate for driving, the electroluminescent device array substrate includes a pixel electrode arranged in an array and switch array for driving the pixels of the pixel electrode. The method comprises the steps of: S1, applied to the completed array substrate of the first drive signal, the first monitor the voltage on the pixel electrode; S2, a second electrode is formed on each pixel electrode array substrate; S3, is formed to have applying a second electrode of the array substrate of the second driving signal, monitoring a second current flowing through the second electrode; wherein the pixel electrode is a cathode and an anode electrically electroluminescent device of the second electrode is said electroluminescent another cathode and the anode of the device. The detection method that do not require an organic light emitting layer, so that the cost of the entire detection procedure is greatly reduced. It also excludes the interference new defects produced in the organic light emitting layer may be introduced brought simplifies the detection process of the display panel, reducing the complexity of testing, help to improve the detection efficiency.
