Summary:Emerging microLED displays continue to demonstrate progress toward display performance improvements that include: higher dynamic range, higher brightness, wider color gamut, and borderless designs. These potential advantages are being pursued for applications such as large area tiled displays smartwatches, and automotive displays. With these advantages, though, challenges to mass production exist related to the unique assembly and integration for microLED displays. Using large-area tiled displays as an example, this paper will outline engineered substrate and electrical interconnect solutions to address the microLED transfer assembly and tiled display integration challenges. This includes precision edged glass substrates with integrated metallized vias for backplane control.
