Abstract: A display device includes pixels connected to scan lines and data lines, each pixel including a driving transistor and at least one light emitting element, and a timing controller configured to generate output data using external input data. The timing controller includes a first compensator configured generate first data by correcting the external input data using at least one of optical measurement information, a threshold voltage of each of the driving transistors, mobility information, dimming information, and temperature information, and an afterimage compensator configured to generate second data based on age information of each light emitting element and the first data, generate third data based on a current amount corresponding to the first data and a current amount corresponding to the second data, and generate the age information by accumulating the third data.

Abstract: A refrigerator includes a storage chamber; an evaporator; an evaporator receiving portion and a defrost water tray slantingly arranged at a lower side of the evaporator receiving portion; a machinery chamber having an evaporation tray; an upper hose communicated with the defrost water tray; a lower hose connected to the upper hose while extending to the evaporation tray, the lower hose being provided, at one side thereof, with an air inlet hole to introduce outside air. The air inlet hole is formed at a slanted mounting surface protruding inside of a vertically-extending portion of the lower hose while being slanted downward. An opening and closing unit is provided in the vertically-extending portion of the lower hose that is configured to open the air inlet hole by an internal pressure of the storage chamber during opening of the door, and to close the air inlet hole by gravity.

Abstract: A refrigerator may include a drain hose assembly. The refrigerator includes an upper hose, a lower hose connected to the upper hose while being arranged in a machinery chamber, the lower hose being provided with an air inlet hole to introduce outside air, and an opening and closing unit provided at the lower hose to be upwardly pivoted by negative pressure in a storage chamber and to be downwardly pivoted by gravity, in order to open and close the air inlet hole, respectively. As a result, it may be possible to achieve an enhancement in energy efficiency and to reduce the force required to open door according to an improvement of sealing-tightness.
