Disclosed are an organometallic compound represented by Formula 1, an organic light-emitting device including the same, and an electronic device including the organic light-emitting device: The detailed description of Formula 1 is the same as described in the present specification.

Organometallic compound, organic light-emitting device including the same, and electronic apparatus including the organic light-emitting device

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

Vacuum cleaner station, vacuum cleaner system, and method for controlling vacuum cleaner station

A cleaner system includes: a cleaner which includes a dust bin having one openable side thereof; and a cleaner station on which the cleaner is mounted. The cleaner includes: a first discharge cover which covers a portion of the open side of the dust bin; and a second discharge cover which covers the rest portion of the open side of the dust bin. The cleaner station includes a dust collection motor which generates a suction force sucking dust within the dust bin. Therefore, the suction force of the dust collection motor is concentrated by opening the second discharge cover first, so that adsorbed small dust is more easily sucked. Large dust is sucked by opening the first discharge cover after the small dust is sufficiently sucked, so that dust is efficiently discharged under the general power of the dust collection motor.

Cleaner system

A cleaner can include a cleaner main body including a suction motor configured to generate a suction force to suction air containing dust on a cleaning surface, the cleaner main body being configured to separate the dust from the air suctioned; a nozzle placed on the cleaning surface and configured to suck the air containing dust on the cleaning surface; and an extension tube to which the nozzle is detachably connected, one end connected to the nozzle and the other end connected to the cleaner main body to guide the air containing dust from the cleaning surface to the cleaner main body.

Nozzle for cleaner

A photodetector includes a gate electrode extending in a first direction, a ferroelectric layer on the gate electrode and maintaining a state of polarization formed by a gate voltage applied to the gate electrode, a light absorbing layer on the ferroelectric layer and extending in a second direction intersecting the gate electrode, the light absorbing layer including a two-dimensional (2D) material of a layered structure, a source electrode on the ferroelectric layer and connected to a first end of the light absorbing layer, and a drain electrode on the ferroelectric layer and connected to the a second end of the light absorbing layer.

Photodetector and image sensor including the same

A negative differential resistance device includes a dielectric layer having a first surface and a second surface opposing the first surface, a first semiconductor layer that includes a first degenerated layer that is on the first surface of the dielectric layer and has a first polarity, a second semiconductor layer that includes a second degenerated layer that has a region that overlaps the first semiconductor layer and has a second polarity, a first electrode electrically connected to the first semiconductor layer, a second electrode electrically connected to the second semiconductor layer, and a third electrode on the second surface of the dielectric layer and which has a region overlapping at least one of the first semiconductor layer or the second semiconductor layer.

Negative differential resistance device

Provided are an organometallic compound represented by Formula 1, an organic light-emitting device including the organometallic compound, and a diagnostic composition including the organometallic compound:M(L)(L)  Formula 1wherein M, L, L, n1 and n2 are each independently the same as defined in the specification.

Organometallic compound, organic light-emitting device including the organometallic compound, and diagnostic composition including the organometallic compound

An embodiment of the disclosure relates to a foldable electronic device including a plurality of cameras, providing a preview image of a camera in response to folding or unfolding of the device and an operating method thereof. A foldable electronic device according to an embodiment of the disclosure may include: a plurality of cameras, at least one display, at least one processor operatively connected with the plurality of the cameras and the at least one display, and at least one memory operatively connected with the at least one processor, and the at least one memory may store instructions which, when executed, cause the at least one processor to: while a first preview image corresponding to a first camera among the plurality of the cameras is displayed on the at least one display, select at least one other camera, based on an analysis result of at least one object included in the first preview image, in response to detecting folding or unfolding of the electronic device, display a second preview image corresponding to the selected at least one other camera, and obtain a captured image based on the displayed second preview image.
