Abstract: A display panel includes a light-providing unit, a display panel and a panel driving unit. The display panel selectively displays an image corresponding to a first driving mode and a second driving mode using light from the light-providing unit. The panel driving unit includes a power supply, a data driver and a gate controller. The power supply includes a first power supply and a second power supply selectively outputting a first power voltage and a second power voltage corresponding to the first driving mode and the second driving mode. The second power voltage is smaller than the first power voltage. The data driver and the gate controller respectively output a data voltage and a gate controlling signal to the display panel corresponding to the driving mode.

Abstract: A home appliance control apparatus and method. The apparatus includes a wireless phone signal reception unit, a search unit, a home appliance control signal generation unit, and a network interface unit. The wireless phone signal reception unit receives a wireless phone signal from the handset of a wireless telephone set, and extracts key information contained in the wireless phone signal. The search unit searches a home appliance control command mapped to the extracted key information. The home appliance control signal generation unit generates a home appliance control signal, including the found home appliance control command. The network interface unit transmits the generated home appliance control signal.

Abstract: Disclosed herein is a system and method for controlling the degree of superheat of an air conditioner. The air conditioner includes a compressor controlled in a pulse width modulation manner according to duty control signals, a condenser, an electronic expansion valve and an evaporator so as to form a refrigeration cycle. An entrance temperature sensor situated at the entrance of the evaporator and an exit temperature sensor situated at the exit of the evaporator are connected to a control unit. The control unit calculates the degree of superheat of the evaporator using the difference between mean entrance and exit temperatures of the evaporator sensed by the entrance temperature sensor and the exit temperature sensor for a period of time corresponding to a duty cycle period of the compressor, and regulates the opening of the electronic expansion valve according to the calculated degree of superheat.

Abstract: An outdoor unit includes a pulse width modulation compressor, an outdoor heat exchanger. First and second outdoor fans are positioned near to the outdoor heat exchanger. The operation modes of the first and second outdoor fans are determined in accordance with the amount of refrigerant discharged from the compressor and external conditions. An outdoor temperature sensor is electrically connected to the input port of the outdoor control unit, and first and second outdoor fan operating units for respectively operating first and second outdoor fans are connected to the output port of the outdoor control unit. The outdoor control unit operates the first and second fans in a preset operation mode by confirming outdoor temperature data input from the outdoor temperature sensor and the loading time of the compressor and controlling the first and second outdoor fan operating units.

Abstract: A system for controlling the starting of an air conditioner includes a compressor controlled in a pulse width modulation according to a duty cycle control signal, an electronic expansion valve for expanding refrigerant compressed in the compressor, a high pressure conduit connecting the exit side of the compressor and the inlet side of the electronic expansion valve, a low pressure conduit connecting the exit side of the electronic expansion valve and the inlet side of the compressor, a bypass conduit connected at its first end to the high pressure conduit and at its second end to the low pressure conduit, and a flow rate regulating valve mounted on the bypass conduit for regulating a flow rate of fluid flowing through the bypass conduit. A control unit controls the compressor during the starting of the compressor in such a way that the electronic expansion valve is open, the flow rate regulating valve is open and a duty control signal shorter than a duty control signal during a normal operation is generated.
