METHOD AND SYSTEM OF TESTING FLAT PANEL DISPLAY INCLUDING ARRAY OF PIXELS AND PERIPHERAL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a method for ensuring proper functionality of a panel prior to LC material injection or OLED material deposition to maximize productivity.SOLUTION: 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 registering 710 a VIOS test head to a panel, applying at least one test signal to the peripheral circuit, acquiring 720 one or more voltage images of the peripheral circuit, and detecting 740 a defect in the peripheral circuit on the basis of the acquired voltage images.
