摘要
A judging method of array test reliability, comprising: Step 1, taking at least one of organic light emitting backplanes subjected to an array test as a sample substrate; Step 2, performing a scan on pixels of the sample substrate row by row and providing a data voltage signal; Step 3, detecting a current that is output to an anode of each pixel from a pixel circuit layer; Step 4, comparing the current that is output to the anode of each pixel from the pixel circuit layer with a predefined current, judging that the pixel is a defective pixel when the two are inconsistent; Step 5, comparing a judgment result of each pixel with a test result of the array test, judging that the array test is reliable when the two are consistent, judging that the array test is unreliable when the two are inconsistent.
