Abstract:
A method of transferring light-emitting diodes including picking up the light-emitting diodes from a base substrate by using a first stamper; rotating the light-emitting diodes by about 90 degrees and arranging the light-emitting diodes over the first stamper or a sacrificial substrate; picking up the rotated light-emitting diodes arranged over the first stamper or the sacrificial substrate by using a second stamper; and releasing the light-emitting diodes from the second stamper towards a display substrate.
