Micro LED Hetero-integration Paves the Way for Innovative Display Applications

The ultimate display technology Micro LED has improved significantly in wafer technology, full color performance and mass transferring recently. Taiwan-based industry players have shared their insights of the technology at an industry gathering last week.

Jennifer Y-C Lin, Senior Associate Vice President of AUO, indicated that Micro LED will be a key technology to drive innovative applications in the era of 5G connection and IoT, especially as the world heavily impacted by the COVID-19 pandemic. She explained that in addition to excellent display performance, Micro LED can be integrated with sensors and driver ICs to create a wide range of human-machine interface enabling various smart interactions between people. Moreover, Micro LED displays are more robust comparing to OLED displays and can be deployed in different scenarios without affected by environmental factors like heat, humidity and more. Therefore, the goal of “Display Everywhere” is more likely to be achieved with Micro LED technology.

Dr. Yen-Hsiang Fang of Electronics and Optoelectronic System Research Laboratories at ITR addressed the edge of adopting Micro LED display technology for AR applications. He pointed out that the hetero-integration connecting Micro LED, Micro sensors and Micro ICs will fully realize next-gen AR applications. AR displays for the future will need to track the movement of eyeballs with lens-free cameras and transmit the real-time data for further information process and interaction with other devices.

“We have to change our mindset when facing Micro LED technology,” highlighted Fang. He considered it more efficiency to first look into the requirements of applications with system and product developers and then trace back to optimize the production for such advanced display technology. Recently ITRI presented a flexible full color Micro LED display module targeting wearable applications and continues to develop Micro LED for AR products.
