An air conditioning device is provided. The device has a fresh air component and a control valve assembly. The fresh air component has a housing assembly and an air treatment assembly. The housing assembly has a ventilation cavity, a fresh air cavity and an exhaust cavity. The air treatment assembly is disposed in the exhaust cavity. The control valve assembly has a first valve assembly and a second valve assembly, which are independent of each other. An outlet of the ventilation cavity is in communication with an indoor space through the exhaust cavity and an air outlet when the first valve assembly is in an open state. The outlet of the ventilation cavity is in communication with the fresh air cavity when the second valve assembly is in an open state.

The disclosure provides a fabricating method of a QLED device and a QLED device. In the fabricating method of a QLED device, a mixed light-emitting layer is formed by doping a quantum dot material with a second hole transporting material having a valence band energy level between the quantum dot material and the first hole transporting material; a stepped barrier between the first hole transporting material and the doped second hole transporting material is used to enhance the hole injection; simultaneously, the first hole transporting material with a higher valence band energy level can block the electrons on one side of the hole transport layer close to the cathode to weaken the injection of electrons into the mixed light-emitting layer, thereby promoting the balance of carriers in the mixed light-emitting layer, improving the carrier recombination efficiency, and then improving the luminous efficiency and brightness of the QLED device.
