Abstract:
1. A light emitting unit array, comprising: a plurality of micro-light emitting diodes arranged in an array on a substrate, each of the micro-light emitting diodes comprising: a reflection layer; a light emitting structure disposed on the reflection layer, and the light emitting structure comprising a first type doped semiconductor layer, an active layer, and a second type doped semiconductor layer that are stacked sequentially; and a light collimation structure, wherein at least a portion of the first type doped semiconductor layer, the active layer, and the second type doped semiconductor layer are sandwiched between the reflection layer and the light collimation structure, and the light collimation structure of each of the micro-light emitting diodes is buried in the first type doped semiconductor layer.
