The control unit 170 of the first display device 100_1 receives a screen interlock request from the remote control device 200 (S109). The controller 170 of the first display device 100_1 may receive a screen link request from the remote control device 200 through the user input interface unit 150. [ The request for screen linkage is a request to display the first content displayed on the first display device 100_1 on the screen linked to the first display device 100_1 and the screen of the second display device 100_2 by interlocking the screen of the first display device 100_1 and the screen of the second display device 100_2 . The controller 170 of the first display device 100_1 transmits a part of the first content to the screen of the first display device 100_1 and the remaining part of the first content to the screen of the second display device 100_2 It is possible to control each display unit 180 to display it on the screen.
In the exemplary embodiment of the present invention, the first display apparatus 100_1 receives the screen link request, but the second display apparatus 100_2 is not limited thereto. The second display apparatus 100_2 may also receive the screen link request. When the second display apparatus 100_2 receives the screen link request, the controller 170 of the second display apparatus 100_2 displays a part of the second content on the screen of the second display apparatus 100_2, The display unit 180 can be controlled to display the remaining portion on the screen of the first display device 100_1.
The control unit 170 of the first display device 100_1 checks whether the second display device 100_2 is reproducing the same content as the first content after receiving the screen link request (S111). The control unit 170 of the first display device 100_1 receives the channel information from the device information received from the second display device 100_2, It is possible to confirm whether the first content being displayed and the second content are identical. More specifically, when the channel number corresponding to the first content is equal to the channel number corresponding to the second content, the controller 170 of the first display device 100_1 determines whether the second display device 100_2 is identical to the first content It can be confirmed that the content is being reproduced. On the contrary, when the channel number corresponding to the first content and the channel number corresponding to the second content are not identical, the controller 170 of the first display device 100_1 transmits the first content and the second content to the second display device 100_2, It can be confirmed that other contents are being reproduced.
If the second display apparatus 100_2 is reproducing the same content as the first content, the controller 170 of the first display apparatus 100_2 transmits a screen link request to the second display apparatus 100_2 S113).
If the second display device 100_2 is reproducing content different from the first content, the control unit 170 of the first display device 100_2 transmits a content switching request for requesting playback to the first content, And transmits the request to the second display device 100_2 (S115). In one embodiment, if the content is a broadcast program, the content change request may be a channel change request indicating a change in the channel. Specifically, when the channel number of the second content being reproduced in the second display device 100_2 is different from the channel number of the first content being reproduced in the first display device 100_1, The control unit 170 may transmit the channel change request to the second display device 100_2 to change the channel number of the first content through the communication unit 195. [ The second display device 100_2 may be tuned to the same channel as the first display device 100_1 in response to the channel switching request.
The control unit 170 of the first display device 100_1 and the control unit 170 of the second display device 100_2 synchronize and reproduce the first content in response to the received screen interlock request at step S117.
Hereinafter, an embodiment will be described in which contents are synchronized and reproduced in response to a screen interworking request.

The pointer 205 moving in correspondence with the movement of the remote control device 200 is positioned on the screen of the first display device 100_1. The control unit 170 of the first display device 100_1 may receive a screen link request from the remote control device 200. [ In one embodiment, the request for a screen link may be generated by a user pushing a button provided in the user input unit 230 of the remote control device 200 for a preset time.
When the first display device 100_1 receives a screen interlock request, the controller 170 of the first display device 100_1 can transmit a screen interlock request to the second display device 100_2. The control unit 170 of the first display device 100_1 transmits a partial image 311 of the first content 310 to the first display device 100_1 according to the received request for linking the screen, The second display device 100_2 may output the remaining image 313 of the first content 310 to the second display device 100_2 in response to the received screen interlock request, Through the display unit 180 of FIG. Accordingly, the entire image of the content can be output on the merged screen in which the screens of the two display devices 100 are combined into one. For example, when the user holds the pointer 205 on the screen of the first display device 100_1 and holds the button provided in the user input part 230 of the remote control device 200 for two seconds, 11 (b) can be provided. As the screens of the two display devices 100 are linked, the user can view the content on a larger screen.
The scaler 175 included in the control unit 170 of each display device 100 scales the image of the first content to a resolution that can be output from the display unit 180 and outputs the scaled image to the display unit 180 ).
According to another embodiment of the present invention, the resolution of the display unit 180 included in the first display device 100_1 may be different from the resolution of the display unit 180 included in the second display device 100_2 . The resolution of each device can be shared with each other in step S103 described in Fig. The control unit 170 of the first display device 100_1 controls the resolution of the display unit 180 included in the first display device 100_1 and the resolution of the display unit 180 included in the second display device 100_2, If it is determined that the content is different, the content can be controlled to be output based on the display unit 180 having a lower resolution. For example, if the resolution supported by the display unit 180 included in the first display device 100_1 is UDH (Ultra Definition) and the resolution supported by the display unit 180 included in the second display device 100_2 The control unit 170 of the first display device 100_1 outputs the content in the HD resolution in response to the request for screen interlocking so that the display unit 180 of the first display device 100_1 and the second The display unit 180_2 of the display device 100_2 can be controlled.

The pointer 205 moving in correspondence with the movement of the remote control device 200 is positioned on the screen of the first display device 100_1. The control unit 170 of the first display device 100_1 may receive a screen link request from the remote control device 200. [ The control unit 170 of the first display device 100_1 may transmit the content switching request and the screen interlocking request to the second display device 100_2 because the contents being reproduced on the respective screens are different from each other.
The second display device 100_2 can convert the content reproduced according to the received content change request from the second content to the first content.
The control unit 170 of the first display device 100_1 displays a partial image 311 of the first content on the display unit 180 of the first display device 100_1 in response to the screen interlocking request, The display unit 180 may display the remaining image 313 of the first content on the display unit 180 of the display unit 100_2.
The user can view any one of the contents on a large screen by simply inputting different contents through the screen of each display device.
Next, Fig. 13 will be described.
Referring to FIG. 13A, the first display device 100_1 displays the first content 310 on the screen, and the second display device 100_2 displays the second content 330 on the screen. . The pointer 205 moving in response to the movement of the remote control device 200 is positioned on the screen of the second display device 100_2. The controller 170 of the first display device 100_1 is configured such that the pointer 205 is positioned on the screen of the second display device 100_2 based on the size information of the first display device 100_1 and the size information of the second display device 100_2 It can be judged. This will be described later.
The controller 170 of the first display device 100_1 may receive the screen link request from the remote control device 200 while the pointer 205 is positioned on the screen of the second display device 100_2. The controller 170 of the first display device 100_1 may recognize that the contents being reproduced are different from each other on the respective screens and may convert the reproduced content from the first content 310 to the second content 330. [ That is, the content displayed according to the screen linkage can be determined based on the screen where the pointer 205 is located.
13B, the controller 170 of the first display apparatus 100_1 transmits a partial image of the second content to the display unit 180 of the first display apparatus 100_1 in response to a screen interlocking request, The display unit 180 may be controlled to display the first image 331 on the display unit 180 of the second display device 100_2 and display the remaining image 331 of the second content on the display unit 180 of the second display device 100_2.
The user can view any one of the contents on a large screen by simply inputting different contents through the screen of each display device.
Next, a process in which the pointer 205 is recognized as being located on the screen of the second display device 100_2 will be described with reference to Figs. 14 to 15. Fig.
14 is a flowchart illustrating a process of recognizing that a pointer is positioned on a screen of a second display device according to an embodiment of the present invention.
Referring to FIG. 14, the controller 170 of the first display device 100_1 obtains size information of the connected second display device 100_2 (S301). The size information of the second display device 100_2 may be obtained through the sharing step (S103) of the device information described in FIG. The size information may include inch information of the second display device 100_2.
The controller 170 of the first display device 100_1 generates a tween virtual area based on the size information of the acquired second display device 100_2 (S303). The tween virtual area may be a virtually created area to determine whether the pointer 205 is located on the screen of the second display device 100_2. The twin virtual area may include an actual area corresponding to the screen of the first display device 100_1 and a virtual area corresponding to the screen of the second display device 100_2. The virtual area can be generated using the size information of the second display device 100_2. The twin virtual area will be described with reference to Fig.
The controller 170 of the first display device 100_1 checks whether the pointer is located in the virtual area included in the twin virtual area (S305). If the pointer is located outside the actual area and is located in the virtual area, The coordinate values are calculated (S307).
The controller 170 of the first display device 100_1 transmits the calculated coordinate value to the second display device 100_2 (S309). Hereinafter, steps S301 to S309 will be described in detail with reference to FIG.
15 is a view for explaining an embodiment for detecting the position of a pointer through a twin virtual area according to an embodiment of the present invention.
15, the twin virtual area 600 is an area generated based on the size information of the real area 610 and the second display device 100_2, which are areas corresponding to the screen of the first display device 100_1 And a virtual area 630. The controller 170 of the first display device 100_1 may use the coordinate values of the virtual area 630 obtained based on the coordinate values of the actual area 610 and the size information of the second display device 100_2, The coordinate values of the area 600 can be obtained. It is assumed that the maximum x-coordinate value of the real area 610 is x1 (i.e., 1920).
The controller 170 of the first display device 100_1 controls the pointer of the virtual area 630 of the tween virtual area 600 to be positioned in the virtual area 630 of the twin virtual area 600. In the case where the pointer 205 is located outside the actual area 610 and located in the virtual area 630, (X2, y2) = (2420, 200), which is the coordinate value of the coordinates (x, y) The controller 170 of the first display device 100_1 can detect the movement distance of the remote control device 200 while sensing that the pointer 205 is out of the real area 610. [ The control unit 170 of the first display device 100_1 uses the coordinate value corresponding to the moving distance of the remote control device 200 to calculate (x2, y2) = (2420, 200), which is the virtual coordinate value of the pointer 205 Can be obtained. The controller 170 of the first display device 100_1 can calculate the x coordinate value 500 obtained by subtracting the maximum x coordinate value 1920 of the actual area 610 from the obtained virtual x coordinate value 2420. [ That is, the controller 170 of the first display device 100_1 can obtain the calculated x-coordinate value 500 and the existing y-coordinate value 200, and can transmit it to the second display device 100_2. The first display device 100_1 and the second display device 100_2 can recognize the points 500 and 200 as points where the pointer 205 is located on the screen of the first display device 100_1 and the second display device 100_2.
16 to 17, a description will be given of a method of synchronizing the same content acquired by the first display device 100_1 and the second display device 100_2 in order to reproduce the same content on a merged screen in response to a screen interlocking request do.
FIG. 16 illustrates a configuration of a control unit according to another embodiment of the present invention, and FIG. 17 illustrates a process of performing synchronization to reproduce content.
In particular, Figs. 16 to 17 show an embodiment in which the first display device 100_1 and the second display device 100_2 acquire the same content through the distributor 171. Fig.
16, the control unit 170_1 of the first display device 100_1 includes an image division unit 172_1, a frame identifier insertion unit 174_1, a frame trimming unit 176_1, a scaler 175_1, a time synchronization unit 177_1. The control unit 170_2 of the second display device 100_2 also includes a video dividing unit 172_2, a frame identifier inserting unit 174_2, a frame trimming unit 176_2, a scaler 175_2, and a time synchronization unit 177_2 .
The image dividing units 172_1 and 172_2 may divide the image of the content received from the distributor 171 into a plurality of frames, as shown in FIG. 17A.
The frame identifier inserters 174_1 and 174_2 may insert a frame identifier capable of identifying each frame into each of a plurality of divided frames. Each frame identifier inserting unit can insert the same identifier into the same frame. As shown in FIG. 17B, the frame identifier inserters 174_1 and 174_2 can insert the same identifier in the same frame as T0, T1 and T2.
The frame trimming sections 176_1 and 176_2 may cut a frame to display only a part of each frame on the display section 180 of each display apparatus 100. [ Specifically, as shown in Fig. 17C, the frame trimming section 176_1 can cut the right half region while leaving only the left half region of each frame, and the frame trimming section 176_2 is located on the right side of each frame The left half area can be cut, leaving only the half area.
The scalers 175_1 and 175_2 can scale each frame that has been cut according to the resolution of each display unit 180. [ Specifically, as shown in FIG. 17C, the scaler 175_1 scales each of the frames that have been cut according to the resolution of the display unit 180_1, and the scaler 175_2 scans each of the frames that have been cut by the display unit 180_1 180_2).
The time synchronization units 177_1 and 177_2 can synchronize the reproduction of each frame using the identifier inserted in each scaled frame. That is, the time synchronization units 177_1 and 177_2 may compare the identifiers of the scaled frames through communication with each other, and if the identifiers of the frames are the same, output the frames to the respective display units 180. Accordingly, the timings of the respective frames are matched, and the video of the content can be displayed in one large screen as shown in Fig. 17 (d).
Next, an embodiment in which the arrangement of each device is automatically or manually set for normal interlocking of the screen of the first display device 100_1 and the screen of the second display device 100_2 will be described.
18 (a) shows a state in which the first display device 100_1 and the second display device 100_2 are normally disposed, FIG. 18 (b) shows a state in which the first display device 100_1 and the second display device 100_2 100_2 are arranged abnormally. That is, it is assumed that the first display device 100_1 is disposed on the left side and the second display device 100_2 is disposed on the right side to be a normal arrangement.
In the case where the first display device 100_1 and the second display device 100_2 are disposed abnormally, the screen interlocking is also performed abnormally, and as shown in FIG. 18 (b), the playback of the content becomes a single large screen It may not be displayed smoothly.
19 is a view for explaining an example of setting the arrangement of the first display device and the second display device manually according to an embodiment of the present invention.
Referring to FIG. 19, each of the first display device 100_1 and the second display device 100_2 may display a plurality of layout setting items for setting a layout. The plurality of layout setting items may include a left layout setting item 710 and a right layout setting item 720. [ When the left positioning setting item 710 displayed on the screen of the first display device 100_1 is selected through the button input of the remote control device 200, the first display device 100_1 can be set to be positioned on the left have. The second display device 100_2 may be set to be positioned on the right side when the right placement setting item 730 is selected on the screen of the second display device 100_2 through the button input of the remote control device 200 .
In one embodiment, the placement setting item may be displayed when each display device 100 enters the twin mode.
20 is a view for explaining a method of confirming the arrangement state of a display device through a speaker provided in each display device and a microphone provided in the remote control device according to another embodiment of the present invention.
20, the first display device 100_1 may include a first left speaker 185_1 and a first right speaker 185_2, the second display device 100_2 may include a second left speaker 185_3, And a second right speaker 185_4. The remote control device 200 is located in front of the first display device 100_1 and the second display device 100_2 and the first display device 100_1 and the second display device 100_2 are disposed in close contact with each other I suppose.
The control unit 170 of each display device 100 can sequentially output test voice signals through the provided loudspeakers. For example, the test voice signal may be outputted in the order of the first left speaker 185_1, the first right speaker 185_2, the second left speaker 185_3, and the second right speaker 185_4. The intensity of each test voice signal may be the same.
The microphone 291 of the remote control device 200 can receive the test voice signal output from each speaker. The control unit 280 of the remote control device 200 can calculate the gain of each test audio signal based on the inputted test audio signal. For example, the gain G1 of the test voice signal output from the first left speaker 185_1 and the gain G1 of the test voice signal output from the second right speaker 185_4 due to the difference in distance between each speaker and the remote controller 200 One of the gains G4 may be the highest gain, and the other may be the lowest gain. Since the first display device 100_1 and the second display device 100_2 are in close contact with each other, the gain G2 of the test audio signal output from the first right speaker 185_2 and the gain G2 of the test audio signal output from the second left speaker 185_3 The magnitude of the gain G3 of the test voice signal may be similar. The first display device 100_1 can receive the gain of each test voice signal from the remote control device 200 and can grasp the position of itself and the position of the second display device 100_2 based on the received gain . For example, when the remote control device 200 is located at a distance closest to the first left speaker 185_1, the test voice signal output from the first left speaker 185_1 is the largest, and the second right speaker 185_1 The size of the test voice signal outputted from the test voice signal 185_4 may be the smallest. Each of the first display device 100_1 and the second display device 100_2 recognizes the position of the speaker. Therefore, the first display device 100_1 can recognize that the test voice signal output from the first left speaker 185_1 is the largest, so that it is disposed on the left side of the second display device 100_2, It can be recognized that the second display device 100_2 is disposed on the right side of the first display device 100_2 since the test voice signal output from the speaker 185_4 is the smallest. In this case, the first display device 100_1 can confirm that the arrangement of the display devices 100 is normal. If the arrangement of each display device 100 is abnormal, the first display device 100_1 displays the screen layout guide window 731 as shown in FIG. 22 to be described later .
Next, Fig. 21 will be described.
FIG. 21 is a view for explaining a method of confirming the arrangement state of a display device through a camera provided in each display device according to another embodiment of the present invention.
Referring to FIG. 21, the first display device 100_1 may include a first camera 191_1, and the second display device 100_2 may include a second camera 191_2 on the upper side. The first camera 191_1 and the second camera 191_2 can take an object A located at the front. The first display device 100_1 can analyze the images photographed by the respective cameras to grasp the arrangement of the display devices 100. FIG. That is, since the first image of the object A photographed by the first camera 191_1 and the second image of the object A photographed by the second camera 191_2 are taken at different angles, (100_1) can analyze the first image and the second image to check the arrangement state of each display device (100).
Meanwhile, the display device 100 may further include a proximity sensor 160 on the side of the display device 100. The proximity sensor 160 may be provided on one side of the display device 100 corresponding to the other display device 100.

Since the first identification screen 1402_1 is displayed on the left side of the captured image, the controller 1060 can determine that the first display device 100_1 is located on the left side. Since the second identification screen 1402_2 is displayed on the right side of the captured image, the controller 1060 can determine that the second display device 100_2 is located on the right side.
67 is an exemplary view of an interface screen displayed on an electronic device when the first display device and the second display device are connected to the electronic device, respectively.
Referring to FIG. 67, when the display devices 100_1 and 100_2 are connected to the electronic device 1000, the control unit 1060 can display the interface screen 1042 on the display unit 1040. FIG. The interface screen 1042 can display a list of the currently connected display devices 100_1 and 100_2 and configurable functions.
In FIG. 67, video position adjustment, menu position setting, and image quality setting are displayed as one example of the configurable functions, but the types of functions that can be set are not limited thereto.
For example, the image position adjustment function may be used to move, adjust the size of the image of the content provided on the merged screen of the first display device 100_1 and the second display device 100_2 or to adjust the position of the image of the content provided between the display devices 100_1 and 100_2 And a function of setting whether or not to display an image of a portion corresponding to the interval of the display area. This will be described in detail with reference to Figs. 71 to 73. Fig.

The image quality setting function means a function of correcting the image quality difference between the image displayed on the first display device 100_1 and the image displayed on the second display device 100_2, Will be described in detail.
The control unit 1060 receives an input for selecting one of the functions from the user input unit 1030 based on the displayed interface screen 1042 and displays a screen for executing one of the functions based on the received input can do.
64 is described again.
Referring to FIG. 64, the electronic device 1000 transmits an image display request for correcting the image quality of the image displayed on the first display device 100_1 and the second display device 100_2 to the first display device 100_1 and the second display device 100_2. 2 display device 100_2 (S1010).
The video display request may be transmitted in response to an input for selecting the image quality setting function displayed on the interface screen 1042 in Fig. 67, and in step S1000, each of the display devices 100_1 and 100_2 and the electronic device 1000 are connected It may be automatically transmitted.
Each of the first display device 100_1 and the second display device 100_2 may display an image in response to the received image display request (S1020). For convenience of explanation, the image displayed on the first display device 100_1 is referred to as a first image quality comparison image, and the image displayed on the second display device 100_2 is referred to as a second image quality comparison image. In this case, in order to compare the image quality of the display devices 100_1 and 100_2, the first image quality comparison image and the second image quality comparison image may be the same image.
The first image quality comparison image and the second image quality comparison image are obtained by comparing the difference in brightness (or brightness) or color (R, G, B) between the first display device 100_1 and the second display device 100_2 And may be a kind of test image including various patterns for correction, but the present invention is not limited thereto.
According to the embodiment, when each of the display devices 100_1 and 100_2 is connected to the electronic device 1000 in step S1000, each of the display devices 100_1 and 100_2 may automatically display a picture quality comparison image.
The control unit 1060 can capture images displayed on the display devices 100_1 and 100_2 using the camera module 1020 (S1030). That is, the control unit 1060 can simultaneously capture the first image quality comparison image displayed on the first display device 100_1 and the second image quality comparison image displayed on the second display device 100_2.
According to the embodiment, before capturing the first image quality comparison image and the second image quality comparison image, the controller 1060 determines whether the first display device 100_1 and the second display device 100_2 are in close contact with each other, The position of the edge of each display unit 180 can be determined.
For example, when the first display device 100_1 is located on the left side and the second display device 100_2 is located on the right side, the right edge of the display portion 180 of the first display device 100_1, The left edges of the display unit 180 of the display unit 100_2 may be adjacent to each other. The control unit 1060 controls the right edge of the display unit 180 of the first display device 100_1 and the left edge of the display unit 180 of the second display device 100_2 using the camera module 1020 The close position or the close position of the edge can be captured to determine the exact position of each edge.
Based on the determination result, the control unit 1060 can distinguish the display units 180 of the display devices 100_1 and 100_2 and can distinguish the first image quality of the display devices 100_1 and 100_2 The comparison image and the second image quality comparison image can be captured.
There is a high possibility that an image quality difference, that is, an unevenness in image quality, may occur partially in the display unit 180 of the display device 100, and in particular, the image quality is unbalanced as the size of the display unit 180 increases. However, in general, the image quality imbalance in the display unit 180 is not easily recognized by the user.
On the other hand, when the display devices 100_1 and 100_2 are in close contact with each other, the image quality difference between the display devices 100_1 and 100_2 on the adjacent surfaces can be more clearly revealed, It can cause inconvenience to the city hall. Accordingly, it is possible to determine the position of each of the edges corresponding to the adjacent portions of the display devices 100_1 and 100_2, and to estimate the image quality difference between the display devices 100_1 and 100_2 based on the position of each of the determined edges The correction is more effective, and the processing performance can also be improved. This will be described in detail with reference to FIG.
68 is an exemplary view illustrating an operation of determining the position of each of edges corresponding to a portion where the first display device and the second display device are adjacent to each other. The images 1403_1 and 1403_2 shown in FIG. 68 are provided for convenience of explanation, and the form of the image is not limited thereto.
Referring to FIG. 68, each of the first display device 100_1 and the second display device 100_2 can display different images. For example, an image displayed on the display unit 180 of the first display device 100_1 is referred to as a first edge image 1403_1 and an image displayed on the display unit 180 of the second display device 100_2 is referred to as a second edge image 1403_1. The first edge image 1403_1 and the second edge image 1403_2 may be displayed on an edge corresponding to a portion where the display devices 100_1 and 100_2 are adjacent to each other. The first edge image 1403_1 and the second edge image 1403_2 may have different colors or patterns to clearly distinguish positions of the display units.
The control unit 1060 of the electronic device 1000 can capture an image including the first edge image 1403_1 and the second edge image 1403_2 using the camera module 1020. [ The control unit 1060 enlarges the first edge image 1403_1 and the second edge image 1403_2 to determine the precise position of the first edge image 1403_1 and the second edge image 1403_2 according to the embodiment. Or may display a message on the display unit 1040 for capturing in close proximity.
The control unit 1060 can determine the position of each of the edges corresponding to the adjacent portions of the display devices 100_1 and 100_2 based on the captured first edge image 1403_1 and the second edge image 1403_2 have. According to the determination result, the controller 1060 can recognize that the image displayed on the left side of the edge corresponding to the adjacent surface of the first display device 100_1 is the image displayed on the first display device 100_1, It can be recognized that the image displayed on the right side of the edge corresponding to the adjacent surface of the second display device 100_2 is the image displayed on the second display device 100_2. Also, the control unit 1060 can recognize that no image is displayed between the edges of the adjacent portions of the display devices 100_1 and 100_2.
64 is described again.
The control unit 1060 of the electronic device 1000 displays the image (first image quality comparison image) displayed on the first display device 100_1 and the image (second image quality comparison image) displayed on the second display device 100_2 The image quality can be compared (S1040). According to the embodiment, the control unit 1060 may display the first image quality comparison image displayed on each of the edges and the second image quality comparison image displayed on each of the edges, based on the positions of the edges corresponding to the adjacent surfaces of the display devices 100_1 and 100_2 determined in FIG. The image quality can be compared with the image quality comparison image.
As a result of the comparison, if the image quality of the first image quality comparison image and the second image quality comparison image are not identical (NO in S1050), the control unit 1060 determines whether any one of the first display device 100_1 and the second display device 100_2 The image quality change signal for changing the image quality setting value of the image quality change signal may be generated, and the generated image quality change signal may be transmitted to any one of the display devices (S1060).
The fact that the image quality of the first image quality comparison image and the second image quality comparison image are not the same may mean that the image quality difference between the first image quality comparison image and the second image quality comparison image is larger than a preset reference range. For example, when the difference between the brightness of the first image quality comparison image and the brightness of the second image quality comparison image is larger than the reference range, the controller 1060 determines that the image quality of the first image quality comparison image and the second image quality comparison image are not the same can do. Accordingly, the controller 1060 may generate an image quality change signal for changing the brightness setting value of any one of the display devices, and may transmit the generated image quality change signal to any of the display devices. The image quality change signal may be generated automatically by the control unit 1060 or may be generated in response to a user input through the user input unit 1030. [
The controller 170 included in the display device receiving the image quality change signal changes the image quality setting value based on the image quality change signal (S1070), and returns to step S1020 to display the image quality comparison image having the changed image quality .
For example, when the image quality difference between the first image quality comparison image and the second image quality comparison image is the brightness difference, the control unit 1060 of the electronic device 1000 displays a high-brightness image, An image quality change signal can be transmitted. The maximum value of the brightness setting value of any one of the display devices may be lower than the maximum value of the brightness setting value of the other display device due to the difference in performance between the display devices.
However, the image quality change signal is not only a signal for lowering the brightness setting value of the display device displaying a high brightness image, but may also be a signal for raising the brightness setting value of the display device for displaying a low brightness image.
If the image quality of the first image quality comparison image is the same as that of the second image quality comparison image (YES in step S1050), the controller 1060 transmits the image quality setting signal to the first display device 100_1 and the second display device 100_2, (S1080). The same image quality of the first image quality comparison image and the second image quality comparison image means that the image quality of the first image quality comparison image and the second image quality comparison image are completely equal to each other, It may mean that the image quality difference between the comparison images is within the preset reference range.
Each of the first display device 100_1 and the second display device 100_2 may store the current image quality setting value in response to the received image quality setting signal (S1090). That is, each of the first display device 100_1 and the second display device 100_2 can correct the image quality difference based on the image quality comparison result of the electronic device 1000.
The steps from S1030 to S1090 will be described in more detail with reference to FIG. 69 to FIG.
69 is an illustration of an image comparison image displayed on each display device to correct a difference in image quality between the first display device and the second display device, Fig. 2 is a diagram illustrating an example of an operation for correcting a defective area; Fig.
69 and FIG. 70 are assumed to be images for comparing brightness differences, the image quality comparison of the display devices 100_1 and 100_2 according to the embodiment of the present invention is limited to brightness comparison 69 and FIG. 70 may be similarly applied in the case of color (R, G, B) comparison of the display devices 100_1 and 100_2.
The first image quality comparison image and the second image quality comparison image displayed on the first display device 100_1 and the second display device 100_2 are displayed on the entire display 180 as shown in Figure 69 (a) Or may be displayed on a part of the display unit 180 as shown in Figure 69 (b). In particular, the first image quality comparison image 1405_1 and the second image quality comparison image 1405_2 displayed on a part of the display unit 180 may be displayed adjacent to each other.
The first image quality comparison image 1405_1 and the second image quality comparison image 1405_2 may be made up of white, gray, and black patterns to compare brightness differences, but the present invention is not limited thereto. For example, when comparing color differences, the first image quality comparison image 1405_1 and the second image quality comparison image 1405_2 may be red (R), green (G), and blue (B) ≪ / RTI >

The control unit 1060 can compare the image quality (brightness) of the captured first image quality comparison image 1404_1 or 1405_1 with that of the second image quality comparison image 1404_2 or 1405_2.
70 (a), when the brightness of the first image quality comparison image 1404_1 or 1405_1 is higher than that of the second image quality comparison image 1404_2 or 1405_2 (in a bright display), the control unit 1060 It can be determined that the brightness of the first display device 100_1 is not the same as the brightness of the second display device 100_2. Accordingly, the control unit 1060 can generate the image quality change signal S1 for lowering the brightness setting value of the first display device 100_1 and transmit the generated image quality change signal S1 to the first display device 100_1 have. According to the embodiment, the controller 1060 may generate an image quality change signal for increasing the brightness setting value of the second display device 100_2, and may transmit the generated image quality change signal to the second display device 100_2.
The image quality change signal S1 may simply be a signal requesting to lower the brightness setting value and may include specific information on the brightness setting value to be changed. The image quality change signal S1 may be generated automatically by the control unit 1060 or may be generated by a request input from the user based on the captured image quality comparison images displayed on the display unit 1040 of the electronic device 1000 .
The controller 170 of the first display device 100_1 may lower the brightness setting value of the first display device 100_1 in response to the received image quality change signal S1. The control unit 170 may display the first image quality comparison image 1404_1 or 1405_1 based on the changed brightness setting value and the control unit 1060 of the electronic device 1000 may use the camera module 1020 to display the first image quality The image including the comparison image 1404_1 or 1405_1 and the second image quality comparison image 1404_2 or 1405_2 can be captured again.
70B, if the brightness of the first image quality comparison image 1404_1 or 1405_1 and the second image quality comparison image 1404_2 or 1405_2 is the same (or the brightness difference is within the preset reference range) The control unit 1060 generates an image quality setting signal S2 for setting (or storing) the current brightness setting value of each of the display devices 100_1 and 100_2 and outputs the generated image quality setting signal S2 to the display devices 100_1, and 100_2, respectively.
Each of the display devices 100_1 and 100_2 can set (store) the current brightness setting value in response to the received image quality setting signal S2.
According to the embodiment, when each of the display devices 100_1 and 100_2 includes a plurality of screen display modes (for example, a movie mode, a standard mode, and the like), the picture quality difference correction operation shown in FIG. 70 can be executed for each mode And each of the display devices 100_1 and 100_2 can store picture quality setting values (brightness setting value, color setting value, color temperature setting value, and the like) for each mode.

The control unit 1060 of the electronic device 1000 captures an image including the first response speed comparison image and the second response speed comparison image displayed on the display devices 100_1 and 100_2 using the camera module 1020 (S1130). The control unit 1060 may capture only a part of the first response speed comparison image and a part of the second response speed comparison image but may capture the entire first response speed comparison image and the entire second response speed comparison image It is possible.
The controller 1060 may compare the response speed (latency) of the first response speed comparison image photographed by the camera module 1020 with the second response speed comparison image (S1140).
The response speed comparison operation of the response speed comparison image and the control unit 1060 will be described in detail with reference to FIGS. 75 and 76. FIG.
75 and 76 show embodiments of the response speed comparison operation between the first display device and the second display device.
75, the controller 1060 captures an image including the first response speed comparison image 1409_1 and the second response speed comparison image 1409_2 using the camera module 1020, and displays the captured response speed It is possible to compare the response speed between the comparison images 1409_1 and 1409_2. Specifically, the control unit 1060 compares the frame of the first response speed comparison image 1409_1 displayed at the same time with the frame of the second response speed comparison image 1409_2 to determine the response speed of the first display device 100_1 And the response speed of the second display device 100_2 can be compared.
The control unit 1060 captures only the response speed comparison images 1409_1 and 1409_2 displayed on the adjacent surfaces of the display devices 100_1 and 100_2 using the camera module 1020 and compares the response speeds , The processing speed of the control unit 1060 can be improved. In this case, as shown in FIG. 75, the second display device 100_2 displays the first response speed comparison image 1409_1 displayed on the first display device 100_1, (1409_2) can be displayed. The first response speed comparison image 1409_1 and the second response speed comparison image 1409_2 may be displayed symmetrically with respect to the adjacent surfaces of the display devices 100_1 and 100_2 so that the response of the controller 1060 The speed comparison operation can be performed more efficiently.
Based on whether the response speed comparison images 1409_1 and 1409_2 display the same frame at the same time as the comparison result, the controller 1060 determines whether or not the response speed of the first display 100_1 and the response of the second display 100_2 It is possible to judge whether or not the speeds are the same.
Referring to FIG. 76, each of the display devices 100_1 and 100_2 may display each of the response speed comparison images in which different pattern frames are inserted between frames of the image. The control unit 1060 can determine whether the response speeds are the same based on the difference in the display time of the same pattern frame in each of the display devices 100_1 and 100_2.
For example, when the second display device 100_2 displays the first pattern frame at the first time point T1 and the first display device 100_1 displays the first pattern frame at the second time point T2, The controller 1060 can determine that the response speed of the second display device 100_2 is faster than the response speed of the first display device 100_1.
74 will be described again.
As a result of the comparison, if the response speed is not the same (NO in S1150), the control unit 1060 sets the response speed for changing the response speed setting value of either the first display device 100_1 or the second display device 100_2 Generates a change signal, and transmits the generated response speed change signal to one of the display devices (S1160).
For example, if it is assumed that the response speed of the first response speed comparison image is faster than the response speed of the second response speed comparison image, the controller 1060 controls the delay of the response speed of the first display device 100_1 A response speed change signal may be generated, and the generated response speed change signal may be transmitted to the first display device 100_1.
The control unit 170 included in any display device that has received the response speed change signal can change the response speed setting value based on the response speed change signal and display the response speed comparison image with the changed response speed ( S1170). For example, when the first display device 100_1 receives the response speed change signal, the controller 170 of the first display device 100_1 may change the response speed setting value to delay (slow down) the response speed .
As a result of the comparison, if the response speed is the same (YES in S1150), the control unit 1060 can transmit a response speed setting signal to each of the first display device 100_1 and the second display device 100_2 (S1180). The response speeds of the first response speed comparison image and the second response speed comparison image are the same when the response speed difference between the first response speed comparison image and the second response speed comparison image is set to a predetermined May be included within the reference range.
Each of the first display device 100_1 and the second display device 100_2 may store the current response speed setting value in response to the received response speed setting signal (S1190). The first display device 100_1 and the second display device 100_2 can display the merged images of the content at a response speed corresponding to the response speed setting value stored in each of the first display device 100_1 and the second display device 100_2.
