Abstract: A method of fabricating a light emitting device for a display, the method including the steps of growing a first LED stack on a first growth substrate, the first LED stack including a first conductivity type semiconductor layer and a second conductivity type semiconductor layer, growing a second LED stack on a second growth substrate, the second LED stack including a first conductivity type semiconductor layer and a second conductivity type semiconductor layer, bonding the second LED stack to a first temporary substrate, removing the second growth substrate from the second LED stack, bonding the second LED stack to the first LED stack, and removing the first temporary substrate from the second LED stack.

Abstract: An air conditioner is disclosed to supply a room with oxygen as well as control temperature and humidity of the air. The present invention includes an outdoor module 10, an indoor module 20, a refrigerant tube 30, and an oxygen generating module. The oxygen generating module includes an oxygen generator 100 installed at the outdoor module 10 so as to generate oxygen by in-taking outdoor air, an oxygen exhauster 200 installed in the indoor module 20 so as to exhaust the oxygen, and an oxygen transport tube 300 transporting the oxygen generated from the oxygen generator 100 to the oxygen exhauster 200.

Abstract: Disclosed is an air conditioner enabling to supply a room with oxygen as well as control temperature and humidity of air therein. The present invention includes an outdoor module 10, an indoor module 20, a refrigerant tube 30, and an oxygen generating module. The outdoor module 10 includes a condenser 11, an outdoor fan 12, and a compressor 13 so as to compress and condense a refrigerant. The indoor module 20 includes an evaporator 21, an indoor fan 22, an inlet 23, and an outlet 24 so as to cool the air in the room. The refrigerant tube 30 connects the evaporator 21 of the indoor module 20 to the condenser 11 of the outdoor module 10 so as to circulate the refrigerant.
