A power supply device according to the disclosure is disposed so as to be spaced apart from a display device and supplies power to the display device, and includes a first power supplier which supplies power to the display device through a cable in a wired manner, a second power supplier which supplies power to the display device in a wireless manner, a detector for detecting whether the power supply device is connected to the display device through the cable, and a processor configured to control the second power supplier in a state in which the display device and the power supply device are disconnected, such that power is supplied in the wireless manner, and control the first power supplier based on detecting connection between the display device and the power supply device, such that power is supplied in the wired manner.

Power supply device for display device by a wired or wireless manner, display system including same, and power selection method for power supply device

An apparatus and method for sensing body information is provided. The apparatus includes: a light-emitting device configured to emit a light signal toward an object that is to be sensed; a light-receiving device configured to detect a reflected light signal reflected from the object; an image sensor configured to detect the reflected light signal reflected from the object; and a controller configured to selectively drive at least one of the light-receiving device and the image sensor according to a distance between the object and the light-emitting device and to sense volume information or blood flow information of the object by using the reflected light signal.

Sensing body information apparatus for volume and blood flow via light reflectance

A display apparatus is provided. The display apparatus includes: a display panel; a backlight unit configured to provide light to the display panel; a signal processor configured to obtain a PWM signal corresponding to a grayscale of an input image; and a driver including a switching element, the driver being configured to control a current applied to the backlight unit by alternately turning the switching element on/off during a section in which the PWM signal provided from the signal processor is in an on-state, and the driver is configured to, based on the grayscale of the input image being greater than or equal to a threshold value, alternately turn the switching element on/off based on a first period, and, based on the grayscale of the input image being less than the threshold value, to alternately turn the switching element on-off based on a second period shorter than the first period.

Display apparatus and control method thereof

A development cartridge for an image forming apparatus includes a photoconductive unit including a photoconductive drum, a developing unit including a developing roller having a rotation shaft and coupled to the photoconductive unit to be rotatable to a release position where the developing roller is separated from the photoconductive drum, and to a development position where the developing roller contacts the photoconductive drum, and a coupler located between and couplable to the rotation shaft of the developing roller and a rotational power transmission member. When the coupler is coupled to the rotational power transmission member, the coupler is selectively rotatable in a first rotation direction or a second rotation direction by a rotational force from the rotational power transmission member. When the coupler is rotated in the first rotation direction and then in the second rotation direction, transmission of the rotational force to the developing roller is partially interrupted.

Development cartridge having a switch member to rotate developing unit to a development position

Provided is a development cartridge mounted on a main body of an image forming apparatus. The development cartridge includes a photoconductive unit, a developing unit coupled to the photoconductive unit so as to rotate to a development position and a release position, and an elastic member that provides an elastic force to maintain the developing unit at the development position. A switching member is mounted on a rotation shaft of the developing roller to be rotatable about a rotation shaft of a developing roller. The switching member is switched to a first state where the switching member contacts an interfering portion of the photoconductive unit and rotates the developing unit to the release position and to a second state where the switching member is separated from the interfering portion and allows the developing unit to rotate to the development position due to the elastic force of the elastic member.

A view sensor, a home control system including the view sensor, and a method of controlling the home control system are provided. The view sensor includes: a lens unit configured to receive light in order to capture an image or project light in order to display the image; an image acquirer configured to acquire the image by using the light received from the lens unit; a projector configured to provide light to the lens unit in order to display the image; a beam splitter configured to provide the image acquirer with the light received from the lens unit or transmit the light generated by the projector to the lens unit; and a controller configured to, in response to the image being captured, control the beam splitter to provide the image acquirer with the light received from the lens and, in response to the image being displayed, control the beam splitter to provide the lens unit with the light generated by the projector.

View sensor, home control system including view sensor, and method of controlling home control system

A development cartridge detachable from a main body of an image forming apparatus includes a photosensitive unit including a photosensitive drum and a developing unit including a developing roller.
