Transfer Printing Enabling Micro-LED Assembly for Flexible Displays

Transfer printing technology offers significant advancements for the electronics and display industry by enabling the precise transfer and integration of microscale devices and materials onto various substrates. This technology has enhanced the fabrication of high-performance electronic components, including flexible, stretchable, and wearable electronic devices. It also supports the high-resolution assembly of micro-LED arrays, crucial for creating displays with superior brightness, color accuracy, and energy efficiency. The speaker will discuss the results of his most recent research into transfer printing for micro-LED assembly in this talk. In particular, he presents a shape memory polymer (SMP)-based transfer printing that mimics the transfer of micro-LED pixels of a comparable size by transferring a large area array of 5 um scale micro-objects and related challenges towards flexible and stretchable display manufacturing.
