Abstract: A cleaner includes: a suction motor that generates suction force; a dust separation unit that is disposed behind the suction motor and separates dust from air sucked by the suction force of the suction motor; a dust container that stores dust separated by the dust separation unit; a handle disposed behind the dust separation unit; a battery housing disposed under the handle; and a battery that is detachably coupled to the battery housing and is separable downward from the battery housing.

Abstract: A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

Abstract: A cleaner includes: a suction unit; a suction motor that generates suction force for sucking air through the suction unit and includes an impeller; a dust separation unit that includes one or more cyclone units generating cyclonic flow to separate dust from air flowing inside through the suction unit; a dust container that stores dust separated by the dust separation unit and is disposed under the suction motor; a battery disposed behind the dust container to supply power to the suction motor; and a handle disposed behind the suction motor, wherein a rotational axis of the impeller and an axis of the cyclonic flow vertically extend and an extension line from the rotational axis of the impeller passes through the one or more cyclone units.

Abstract: In some embodiments, the effect of uniformly dispersing carbon nanotubes in the material is achieved by including Ag in the carbon nanotubes to suppress the aggregation of carbon nanotubes when the electrical contacts are prepared.

Abstract: A display apparatus includes: a display panel; a deformation sensor configured to sense a bending of the display panel; and a controller configured to control the display panel, wherein the controller is configured to: control displaying a plurality of objects on the display panel; detect the bending of the display panel through the deformation sensor; divide the display panel into a first area and a second area with respect to a bending line defined by the bending; divide the objects into a first object corresponding to the first area and a second object corresponding to the second area according to the bending; and move the first and second objects in first and second directions, respectively, according to the bending.

Abstract: An automotive display device on which an image may be displayed, the automotive display device being for a vehicle interior, the automotive display device including an automotive frame, at least part of the automotive frame being bendable; and a bending controller to control bending of the automotive frame.
