Emissive displays using microLEDs will be bright, rugged, and efficient. Realization of microLED displays requires high‐yield mass transfer processes that rapidly assemble millions of micron‐scale devices onto non‐native display substrates. A candidate mass transfer process uses polydimethylsiloxane (PDMS) elastomer stamps to retrieve and transfer large arrays of microLEDs. This paper will review the fundamentals of elastomer stamp mass transfer and will examine paths to satisfy the demanding throughput requirements for display manufacturing.
