    Abstract: Discussed is a display device including a substrate, semiconductor light-emitting elements on the substrate, flip-flops which can apply an electrical signal to the semiconductor light-emitting elements to maintain the semiconductor light-emitting elements in a light-emitting state for a predetermined time interval, scan electrodes and data electrodes electrically connected to the flip-flops, respectively, and a driver. When a frame synchronization signal is generated during a time interval from a time point of the generation of a sub field signal to a time point of the generation of a subsequent sub field signal, the driver can prevent a voltage from being applied to the data electrodes for the time interval.

    Abstract: Disclosed is a method of controlling an air conditioner including a step of sensing the capacitance of condensed water through any one of a plurality of electrode pads to sense the level of the condensed water during cooling, and a step of operating a drainage pump based on the level of the condensed water sensed through any one of the electrode pads to drain the condensed water stored in the condensed water storage part. A water level detecting device of the air conditioner more accurately senses the level of condensed water based on the capacitance of the condensed water, thereby effectively controlling the drainage pump.

    Abstract: Disclosed is an air conditioner. The air conditioner of the present disclosure includes: an outdoor unit; at least one indoor unit configured to cool and heat an indoor space while repeating operation (Thermo-ON) and operation stop (Thermo-OFF); a sensor unit configured to measure a temperature and humidity of each indoor space where the at least one indoor unit is located; and a controller, wherein the controller calculates a sensible heat load and a latent heat load of each indoor space, based on a time when the operation stop occurs, a time when the operation starts again after the operation stop occurs, and temperature and humidity information of each indoor space, derives target sensible heat and target latent heat based on the calculated sensible heat load and latent heat load, and derives a target refrigerant temperature and an air volume of the at least one indoor unit based on the target sensible heat and the target latent heat. Accordingly, indoor sensible heat and latent heat loads can be accurately derived, and the operation efficiency of the air conditioner can be improved.
