Claim 0:
1. A method of transferring light emitting diodes (LEDs), comprising:
providing first LEDs configured to emit first color light and located on a first substrate, and second LEDs configured to emit second color light different from the first color light and located on a second substrate;
transferring a first subset of the first LEDs to a first subset of bonding structures on a first backplane to form first subpixels in pixel regions and separating the first subset of the first LEDs from the first substrate;
transferring a first subset of the second LEDs to a second backplane and separating the first subset of the second LEDs from the second substrate to leave first vacancies on the second substrate;
forming an additional electrically conductive material on a second subset of second LEDs located on the second substrate after transferring the first subset of the second LEDs to the second backplane;
positioning the second substrate over the first backplane, such that the first subpixels are disposed in the first vacancies; and
transferring the second subset of the second LEDs to a second subset of bonding structures on the first backplane to form second subpixels in the pixel regions, while a gap exists between the first subpixels and the second substrate due to the presence of the additional electrically conductive material.
