Unleashing microLED’s Future: The Power of Electroluminescence Testing

Despite their promise, microLED displays have yet to achieve mass commercialization, with yield improvement being a critical hurdle. Effective testing is essential to overcoming this challenge. This talk will explore the two major functional testing methodologies—photoluminescence (PL) and electroluminescence (EL)—and demonstrate why EL is the superior approach for accurate defect detection and performance assessment. We will discuss the key advantages of EL testing and examine what the industry needs in order to adopt this methodology at scale, ultimately driving microLED technology toward widespread adoption.
