Abstract (en)

[origin: TW202101063A] Disclosed herein are techniques for forming a thin-film circuit layer on an array of light-emitting diodes (LEDs). LEDs in the array of LEDs can be singulated by various processes, such as etching and ion implantation. Singulating LEDs can be performed before or after forming the thin-film circuit layer on the array of LEDs. The array of LEDs can be bonded to a transparent or non-transparent substrate.
