Methods for forming a pixel of a light-emitting diode light source and a plurality of light-emitting diode pixels arranged in a two-dimensional array

A method for forming a pixel of a light-emitting diode light source, the method comprising:

• forming a first layer on a first substrate;
• forming a second layer and a first light-emitting active layer on the first layer;
• forming a first intermediate layer on the second layer;
• forming a third layer on a second substrate;
• forming a fourth layer and a second light-emitting active layer on the third layer;
• and
• placing the third layer, the fourth layer, and the second light-emitting active layer on the first intermediate layer,
• wherein the first light-emitting active layer and the second light-emitting active layer emit different colors of light.

A method for forming a plurality of light-emitting diode pixels arranged in a two-dimensional array, the method comprising:

• forming a plurality of first layers arranged in a two-dimensional array on a first substrate;
• forming a plurality of second layers and a plurality of first light-emitting active layers on the first layers correspondingly;
• forming a plurality of first intermediate layers on the second layers;
• forming a plurality of third layers arranged in a two-dimensional array on a second substrate;
• forming a plurality of fourth layers and a plurality of second light-emitting active layers on the third layers correspondingly;
• and
• placing the third layers, the fourth layers, and the second light-emitting active layers on the first intermediate layers,
• wherein the first light-emitting active layers and the second light-emitting active layers emit different colors of light.
