Abstract

See full text

A method for transferring micro light emitting diodes (micro-LEDs) includes forming a plurality of micro light emitting diode (micro-LED) chips having an epitaxial stacked layer and an electrode on a base; attaching the electrodes of the micro-LED chips to a temporary substrate and removing the base from the micro-LED chips; forming a light shielding layer on the temporary substrate; forming a light-transmissible packaging layer to cover the light shielding layer and the micro-LED chips; removing the temporary substrate to form a light emitting assembly; dividing the light emitting assembly to separate a plurality of pixels constituted by the micro-LEDs; and transferring the pixels to a permanent substrate.
