Abstract: A method of testing a flat panel display including an array of pixels and a peripheral circuit configured to provide signals to the pixels is disclosed. The method includes applying at least one test signal to the peripheral circuit, acquiring one or more voltage images of the peripheral circuit, and detecting a defect in the peripheral circuit based on the acquired voltage images.
