Abstract

A display apparatus of a plurality of display apparatus constituting a wall display includes a first board, a second board, and a plurality of display modules. The first board includes a first communication interface including a circuitry for wireless transmission, and a timing controller configured to, in response to information on an image being received, generate a plurality of driving signals for driving the plurality of display modules based on the received information and transmit the plurality of driving signals to the second board through the first communication interface. The second board includes a second communication interface including circuitry for wireless reception, a plurality of interfaces electrically connected to the plurality of display modules, and an IC chip configured to, based on the plurality of driving signals being received through the second interface, provide each of the received driving signals to each of the display modules.

Claims (53)

1 . A display apparatus among a plurality of display apparatuses constituting a wall display, the display apparatus comprising:

a first communication interface configured to be connected with an external apparatus via a cable;

a second communication interface configured to be connected wirelessly with another display apparatus among the plurality of display apparatuses; and

one or more processors configured to:

receive image information from the external apparatus through the first communication interface;

based on the image information, generate a driving signal;

based on the generated driving signal, display a portion of the image information; and

control the second communication interface to provide the image information to the another display apparatus,

wherein the portion of the image information is a portion area corresponding to the display apparatus of an entire area according to the image information that is providable through the wall display, and

wherein the display apparatus corresponds to one of display apparatuses positioned at a lower part among the plurality of display apparatuses constituting the wall display.

2 . The display apparatus of claim 1 , wherein the one or more processors control the second communication interface to provide the image information only to the another display apparatus.

3 . The display apparatus of claim 1 , wherein the one or more processors are further configured to:

identify the portion area corresponding to identification information of the display apparatus, and

control the second communication interface to provide the image information to the another display apparatus to cause the another display apparatus to display another portion of the image information.

4 . The display apparatus of claim 1 , further comprising:

a first contact terminal; and

a second contact terminal configured to provide power received through the first contact terminal to the another display apparatus.

5 . The display apparatus of claim 1 , wherein the first communication interface is provided at a first side of the display apparatus, and

the second communication interface is provided at a second side of the display apparatus, the second side being adjacent to the another display apparatus and opposite to the first side of the display apparatus.

6 . The display apparatus of claim 1 , wherein the another display apparatus is coupled adjacent to the display apparatus.

7 . The display apparatus of claim 1 , further comprising:

at least one connecting part configured to couple to the another display apparatus.

8 . The display apparatus of claim 1 , further comprising:

a first display module; and

a second display module, and

wherein the one or more processors are further configured to:

display the portion of the image information by controlling the first display module based on a first driving signal corresponding to the first display module and controlling the second display module based on a second driving signal corresponding to the second display module.

9 . The display apparatus of claim 8 , wherein the second display module is separate from the first display module, and

wherein the first display module is physically connected to the second display module.

10 . A method of controlling a display apparatus among a plurality of display apparatuses constituting a wall display, the method comprising:

receiving image information from an external apparatus through a first communication interface connected by wire with the external apparatus;

based on the image information, generating a driving signal;

based on the generated driving signal, displaying a portion of the image information; and

providing the image information to another display apparatus among the plurality of display apparatuses through a second communication interface wirelessly connected with the another display apparatus wirelessly,

wherein the portion of the image information is a portion area corresponding to the display apparatus of an entire area according to the image information that is providable through the wall display, and

wherein the display apparatus corresponds to one of display apparatuses positioned at a lower part among the plurality of display apparatuses constituting the wall display.

11 . The method as claimed in claim 10 , wherein the providing the image information comprises providing the image information only to the another display apparatus.

12 . The method as claimed in claim 10 , further comprising:

identifying the portion area corresponding to identification information of the display apparatus, and

wherein the providing comprises providing the image information to the another display apparatus to cause the another display apparatus to display another portion of the image information.

13 . The method as claimed in claim 10 , further comprising:

based on receiving power through a first terminal, providing the power to the another display apparatus through a second terminal.

14 . The method as claimed in claim 10 , wherein the first communication interface is provided at a first side of the display apparatus, and

the second communication interface is provided at a second side of the display apparatus, the second side being adjacent to the another display apparatus and opposite to the first side of the display apparatus.

15 . The method as claimed in claim 10 , wherein the another display apparatus is coupled adjacent to the display apparatus.

16 . The method as claimed in claim 10 , wherein the display apparatus further comprises:

at least one connecting part configured to couple to the another display apparatus.

17 . The method as claimed in claim 10 , wherein the display apparatus further comprises:

a first display module; and

a second display module, and

wherein the displaying comprises displaying the portion of the image information by controlling the first display module based on a first driving signal corresponding to the first display module and controlling the second display module based on a second driving signal corresponding to the second display module.

18 . The display apparatus of claim 17 , wherein the second display module separate from the first display module, and

wherein the first display module is physically connected to the second display module.
