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...

The key for commercializing Micro LED technology is to holistically improve the manufacture process and to achieve cost-effective high volume production of Micro LED displays. Major industry players in the production chain from the LED chip makers, transfer technology developers to panel producers and end products brands have all dedicated themselves to work on solutions for the goal. Tesoro Scientific, established by Francois J. Henley in 2017, focuses on the enhancement of Micro LED production. Its research paper, titled “Novel In-Process Functional Tes...

The “Micro LED Technology Research Contest” held by LEDinside has received numerous articles providing innovative and practical solutions to enhance the manufacturing of Micro LED during June 6th – September 10th, 2018. LEDinside was very excited to learn all these novel ideas and technologies offered by different institutes and companies from all over the world. Selecting the winning articles was a tough task as most of them have proposed unique perspectives on how to solve the mass transfer issue of Micro LED or improve their yield rate.
