Abstract:
A pairing apparatus and method are provided. The pairing apparatus includes: a first communicator configured to broadcast a search signal over a first communication method, and to receive, from the external communication apparatus, a first response signal in response to the search signal; a second communicator configured to receive a second response signal via a second communication method having a shorter transmission range than the first communication method; and a controller configured to, in response to the first communicator receiving the first response signal and the second communicator receiving the second response signal, control to perform a pairing with the external communication apparatus, wherein the second communicator is periodically activated while the pairing apparatus is turned on, and an activation period of the second communicator is set adaptively according to a transmission period of the second response signal.
Abstract:
A power supplying apparatus, a power supplying method, an organic light-emitting diode (OLED) display apparatus are provided. The OLED display apparatus includes: a plurality of components which are to perform an operation of the OLED display apparatus; a power supplying unit; a rectifier which rectifies an input voltage supplied from the power supplying unit; and a voltage level converter which converts a level of the input voltage rectified by the rectifier and supplies the input voltage having the converted level to the plurality of components.
Abstract:
A user terminal apparatus including: a display; a communicator configured to communicate with a display apparatus; a state determiner configured to determine an arrangement state of the user terminal apparatus; and a controller configured to control, in response to the user terminal apparatus being changed to a predetermined arrangement state, the communicator to transmit information on the arrangement state to the display apparatus and receive information related to content currently displayed on the display apparatus, to divide a screen of the display into a plurality of display regions, and to control the display to display the received information on at least one of the plurality of display regions.
Abstract:
A user terminal apparatus includes: a first communicator configured to receive content information about a content displayed on a display apparatus; a second communicator configured to communicate with an external apparatus; a display configured to display a text input screen; an inputter configured to receive a text and a user command; and a controller configured to, in response to the content information being received through the first communicator, add tag information corresponding to the content information to the text input screen and display the tag information, and control the second communicator to transmit a text added with the tag information to the external apparatus.
Abstract:
A display apparatus constituting a video wall system is provided. The display apparatus includes a display, a first communicator configured to perform communication with at least one adjacent display apparatus, and a processor configured to allocate identification information corresponding to the display apparatus based on identification information received from the adjacent display apparatus and information on a location relationship of the display device relative to the adjacent display apparatus and display a sub-image of an image through the display based on the allocated identification information.
Abstract:
A broadcast receiving apparatus and a method for tuning a channel of a broadcast receiving apparatus is provided. The method includes displaying contents received through a broadcast channel, changing, if a channel zapping command is received, the broadcast channel, displaying, if the channel zapping command is consecutively received a plurality of times within a predetermined amount of time, a user interface (UI) using which a user can select a broadcast channel, and tuning, if a broadcast channel is selected from the UI, the selected broadcast channel.
Abstract:
A light emitting diode (LED) driving apparatus includes a DC-DC converter which provides a driving voltage to a plurality of LED arrays; a plurality of switching units, each of the switching units being connected in series to a corresponding LED array of the plurality of LED arrays and varying a size of a driving current to flow in the corresponding LED array of the plurality of LED arrays; and a control unit which, in order for each of the switching units to operate within a predetermined headroom voltage range, calculates a driving current of each of the plurality of LED arrays and a duty cycle of the switching units corresponding to each of the plurality of LED arrays, and controls the plurality of switching units based on the calculated driving current and the calculated duty cycle.
