An air conditioner including: a compressor; a heat exchanger fluidly connected to the compressor; a pressure sensor provided in a first flow path connecting an outlet of the compressor to an inlet of the first heat exchanger; a temperature sensor provided in a second flow path connected to an outlet of the heat exchanger; and a processor connected to the compressor, the pressure sensor, and the temperature sensor. The processor configured to: acquire a reference index value based on a first reference pressure measured by the pressure sensor and a first reference temperature measured by the temperature sensor, acquire a measurement index value based on a first measurement pressure measured by the pressure sensor and a first measurement temperature measured by the temperature sensor, and display a shortage of a refrigerant of the air conditioner based on the reference index value and the measurement index value.

Air conditioner and controlling method thereof

Various embodiments of the disclosure disclose a method for manufacturing a micro Light Emitting Diode (LED) display. The disclosed manufacturing method may include coating a face of a substrate including a circuit portion with a first thickness of a polymer adhesive solution containing a plurality of metal particles, attaching an array of micro LED chips on the polymer adhesive solution, physically connecting a connection pad for each of the array of micro LED chips to the metal particles through heating and pressing the attached plurality of micro LED chips to descend through the polymer adhesive solution, and chemically bonding the metal particles to the connection pad and the circuit portion through heating and pressing so that the micro LED chips are electrically connected to the circuit portion. Various other embodiments are also possible.

Micro LED display and manufacturing method therefor

An air conditioner and control method for reducing power consumption by controlling pressure or temperature of a refrigerant. The air conditioner includes a compressor compressing a refrigerant and discharging a high pressure refrigerant gas; an outdoor heat exchanger in which the high pressure refrigerant gas is changed to a refrigerant fluid; an outdoor fan to blow outdoor air to the outdoor heat exchanger; a decompressor decompressing the refrigerant fluid into a low pressure state; an indoor heat exchanger changing the decompressed low pressure refrigerant fluid to a refrigerant gas; and a controller configured to control pressure or temperature of the refrigerant based on an operation condition including at least two of a first condition determined based on an installation environment, a second condition determined based on an optimal compression ratio of the compressor, a third condition determined based on outdoor temperature, and a fourth condition set as a default value.
