Claim 10:
11. A method for making a micro LED display panel, comprising:
forming a blue LED layer, the blue LED layer comprising a plurality of blue micro LEDs spaced apart from each other, each of the plurality of blue micro LEDs defining a blue sub-pixel;
forming a green LED layer, the green LED layer comprising a plurality of green micro LEDs spaced apart from each other, each of the plurality of green micro LEDs defining a green sub-pixel;
forming a red LED layer, the red LED layer comprising a plurality of red micro LEDs spaced apart from each other, each of the plurality of red micro LEDs defining a red sub-pixel; and
stacking the blue LED layer, the green LED layer, and the red LED layer one by one along a direction; wherein each of the plurality of blue micro LEDs, each of the plurality of green micro LEDs, and each of the plurality of red micro LEDs are staggered from each other;
wherein the green LED layer comprises a second transparent conductive layer, a second light emitting layer, and a second electrode layer stacked one by one along the depth direction; the second light emitting layer is between the second transparent conductive layer and the second electrode layer; the second light emitting layer comprises a N-type doped inorganic light emitting layer, an active layer, and an P-type doped inorganic light emitting layer stacked one by one along the depth direction; the active layer is between the P-type doped inorganic light emitting layer and the N-type doped inorganic light emitting layer; the N-type doped inorganic light emitting layer comprises a plurality of N-type doped units spaced apart from each other; the second electrode layer comprises a plurality of electrodes spaced apart from each other; each of the plurality of N-type doped units is coupled to the second transparent conductive layer; the P-type doped inorganic light emitting layer is coupled to each of the plurality of electrodes; a projection of each of the plurality of N-type doped units on the second electrode layer overlaps with one of the plurality of electrodes; a portion of the green LED layer corresponding to one of the plurality of N-type doped units defines one green sub-pixel.
