ABSTRACT:
A method and a system for testing a plurality of driver circuits of an AMOLED before OLEDs are formed are provided. Each driver circuit includes a terminal, which is connected to an OLED after the OLED is formed, and is connected to a test element to form an electrical loop during the test. The system selects one specific driver circuit to test. The method and the system measure the value of a current signal flowing through the test element, and then analyze it to determine the status of the driver circuit. The said steps executed repeatedly, all driver circuits of the AMOLED are tested efficiently and precisely.
