Light-emitting unit array

A light-emitting unit array, comprising:

• a plurality of light-emitting units arranged and integrated monolithically in an array, each of the light-emitting units comprising:
• a first doped type layer;
• a second doped type layer;
• and
• a light emission layer disposed between the first doped type layer and the second doped type layer;
• a micro collimation array fabricated on the light emitting units, wherein the micro collimation array includes a plurality of micro collimation devices;
• and
• a circuit substrate disposed under the light-emitting units, wherein the circuit substrate comprises a plurality of transistors respectively electrically connected to the light-emitting units.
