The Challenges of Micro LED Display Inspection and Repair

In the manufacturing process of Micro LED display, inspection and repair technologies are indispensable to enhance and assure production yield. But again, given the massive amount of Micro LED chips in tiny size, Micro LED display makers face a great challenge for the testing and repairing process. LED testing includes photoluminescence (PL) and electroluminescence (EL) test, the former method can test LED chips without touching and ruining them but it might not detect all the defects compared to EL test. On the contrary, EL test is able to identify more defec...
