Abstract
An apparatus and associated method for high speed and/or mass transfer of electronic components onto a substrate comprises transferring, using an ejector assembly, electronics components (e.g., light emitting devices) from a die sheet onto an adhesive receiving structure to form a predefined pattern including electronic components thereon, and then transferring the electronic components defining the predefined pattern onto a substrate (e.g., a translucent superstrate) for light emission therethrough to create a high-density (e.g., high resolution) display device utilizing, for example, mini- or micro-LED display technologies.
