Abstract:
A method for manufacturing a display panel comprising light emitting device including micro LEDs includes providing multiple donor wafers having a surface region and forming an epitaxial material overlying the surface region. The epitaxial material includes an n-type region, an active region comprising at least one light emitting layer overlying the n-type region, and a p-type region overlying the active layer region. The multiple donor wafers are configured to emit different color emissions. The epitaxial material on the multiple donor wafers is patterned to form a plurality of dice, characterized by a first pitch between a pair of dice less than a design width. At least some of the dice are selectively transferred from the multiple donor wafers to a common carrier wafer such that the carrier wafer is configured with different color emitting LEDs. The different color LEDs could comprise red-green-blue LEDs to form a RGB display panel.
