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...

Epitaxy Wafer: The Fundamental Phase for Micro LED Display

In the latest report of LEDinside, titled “LEDinside 2019 Micro LED Next Generation Display Key Technology Report,” Micro LED technology not only features excellent performance in brightness and contrast that surpass OLED, its fast response time, low power consumption and reliability make it a perfect option for mobile and automotive applications. However, complicated production process which leads to low yield and high production cost has slowed down the commercial progress of Micro LED display. One of the challenges lies in the quality of Micr...
