Abstract: A display apparatus is provided. The display apparatus includes a communication interface; a display; and a processor configured to control the communicator to receive a content image from a server, control a screen of the display to display the content image and a first image, determine a size of the first image as displayed on the screen of the display apparatus, generate a second image by resizing the first image in response to determining the size of the first image does not correspond to a sensible size, and control the screen of the display to display the content image and the second image.

Abstract: A video wall system for displaying a video wall image is provided. The video wall system includes a plurality of display apparatuses configured to display a video wall image, and each of the plurality of display apparatuses includes a signal processor, a display and a controller. The signal processor is configured to process an image signal of a video wall image. The display scans in one of a first scanning direction and a second scanning direction opposite the first scanning direction based on the processed image signal to display an individual image split from the video wall image. The controller controls the display to scan in one of the first scanning direction and the second scanning direction determined based on a scanning direction of an adjacent other display apparatus. With this, the video wall system may display the video wall image without generating steps caused by differences in screen playing speed between adjacent display apparatuses.

Abstract: A video wall system is provided. The video wall system includes a first display apparatus and a second display apparatus. The first display apparatus displays a first individual image which corresponds to a first area of a first video wall image, and transmits the first video wall image to the second display apparatus; and, in response to an execution condition for anti-screen burn operation being satisfied while the first individual image is displayed, generates a second video wall image by changing the first video wall image, displays a second individual image which corresponds to the first area of the generated second video wall image, and transmits the generated second video wall image to the second display apparatus. The second display apparatus displays a third individual image which corresponds to a second area of one video wall image of the first video wall image and the second video wall image received from the first display apparatus, wherein the second area is different from the first area.

Abstract: A display device configured to communicate with at least one other display device connected to a network is disclosed. The display device includes communication circuitry configured to receive unique information and a service set identifier (SSID) from each of the at least one other display device, the unique information for use in identification of each of the at least one other display device, and a controller configured to change an SSID based on a comparison between unique information of the display device and at least one piece of the received unique information.

Abstract: A display apparatus and a display method according to example embodiments are disclosed. The display apparatus according to an example embodiment includes a display and a processor configured to provide, on the display, a user interface for changing a configuration of a power saving mode such that the display apparatus consumes predefined power in a low-power mode, based on a low-power mode entering history of the display apparatus.

Abstract: A portable communication apparatus is provided. The portable communication apparatus includes: a camera module configured to capture a plurality of test images that are sequentially output from a display apparatus; a microphone module configured to record a test voice that is output from the display apparatus; a communication interface unit configured to communicate with the display apparatus; and a controller configured to control the communication interface unit to calculate an output time difference between the plurality of test images and the test voice to test a synchronization state of the display apparatus and transmit the test result to the display apparatus.

Abstract: A display device and methods thereof. A display device may include a current limit control signal generator to output a current limit control signal according to an input display data, a RGB common gamma adjuster to adjust a value of a RGB common gamma setting signal input via a current limit control signal, a gamma divider to divide a RGB common gamma setting signal having a value adjusted by a RGB common gamma adjuster, and/or a gray amplifier to output a gray signal to drive a display screen by amplifying a signal divided by a gamma divider. A display device may have an automatic current limit function applicable to substantially all kinds of display screen, substantially without additional circuits for data calculation.
