-18. (canceled)
A method for fabricating a light-emitting diode (LED) display panel, comprising:
- forming a transparent processing layer over an LED array, the LED array including a plurality of LED dies;
- and
- processing a portion of the transparent processing layer to transform the portion into a micro lens array having a plurality of micro lenses, each of the micro lenses corresponding to and arranged over at least one of the LED dies.
A method for fabricating a light-emitting diode (LED) display panel, comprising:
- providing a semiconductor epitaxial wafer having a semiconductor epitaxial layer formed on a semiconductor substrate, the semiconductor epitaxial layer including a plurality of LED dies on one side of the semiconductor epitaxial layer;
- aligning and bonding the semiconductor epitaxial wafer onto a driver circuit wafer having a plurality of driver circuits, each of the LED dies being bonded to one of the driver circuits;
- removing the semiconductor substrate;
- and
- processing the semiconductor epitaxial layer from another side opposite to the LED dies to form a plurality of micro lenses, each of the micro lenses corresponding to and arranged over at least one of the LED dies.
