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.

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. 18B, 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. [ For example, the proximity sensor 160 may be provided on each of the left side surface and the right side surface of the display device 100.

Next, when displaying the partial image of the content through the first display device 100_1 and displaying the remaining image of the content through the second display device 100_2 according to another embodiment of the present invention (i.e., Mode), a method for solving the problem that the brightness of each image is changed as the average picture level (APL) of the partial image is different from the APL of the remaining image will be described.
Figs. 62 to 64 are diagrams for explaining how the brightness of an image displayed on each display device varies in the twin mode in which two display devices are arranged adjacent to each other.
Referring to FIG. 62, the first display device 100_1 displays a partial image 6210 of the entire image of the content, and the second display device 100_2 displays the remaining image 6230 of the entire image of the content .
62, the brightness of the partial image 6210 of the content displayed by the first display device 100_1 is brighter than the brightness of the remaining image 6230 of the content displayed by the second display device 100_2 . This is because the average picture level (APL) of the picture input to each display device is changed and the corresponding peak luminance (peak luminance) is changed.
This is explained in more detail through the relationship between APL and Peak Luminance Control (PLC).
First, the APL will be described.
In order to effectively reduce the power consumption of the display device, it is necessary to lower the brightness of the screen which greatly affects power consumption. However, simply lowering the brightness can lower the power consumption, but the image quality may deteriorate. For example, if a user lowers the brightness of a display image, the brightness may be excessively lowered in a bright image having a high APL. The APL can be defined as the brightness average of the brightest color in one image frame, and can be expressed as Equation (1).
[Equation 1]
Here, R means red data, G means green data, and B means blue data. Max (R, G, B) is the maximum value among R, G, and B, and SUM {Max (R, G, B) An image having a large number of bright pixel data has a high average image level APL. On the other hand, a picture with a small number of bright pixel data has a low average picture level APL.
Describes the relationship between APL and Peak Luminance Control (PLC).
FIG. 63 is a graph showing a PLC curve for controlling luminance according to the APL, and FIG. 4 is a diagram showing a state in which a luminance value corresponding to each of a plurality of PLC points constituting a PLC curve is converted into a digital value.
Hereinafter, the luminance when APL = 25% is referred to as peak luminance, and the luminance with APL = 100% is referred to as full white luminance. The peak luminance is higher because the screen load is lower than the full white luminance. In the case of an OLED display, more current flows through the OLED of pixels at the peak luminance and emits brighter than full white luminance. The peak luminance control (PLC) method (hereinafter referred to as "PLC control method") reduces the power consumption by lowering the luminance as the APL is increased based on the PLC curve.
The PLC curve, shown in Figure 63, defines the maximum luminance of a pixel. The pixels of the display panel emit light below the maximum luminance limited by the PLC curve. The PLC curve increases the maximum luminance of the pixels at the low APL to the peak luminance level while defining the luminance values according to the APL to lower the maximum luminance of the pixels as the APL increases. The data including information on the PLC curve may include only data for a certain number of PLC points P0 to P7 to reduce the amount of data to be processed. Each PLC point can be a point located at the boundary between neighboring sections when the PLC curve is equally divided into N sections. Each PLC point can represent the corresponding point between APL and peak luminance. FIG. 64 shows an example in which the number of PLC points is eight. Referring to Fig. 4, the digital luminance values corresponding to each of the eight PLC points P0 to P7 are shown.
A timing controller (T-con), which will be described later, can lower the brightness of the display device based on the PLC curve, and thus the current flowing in the OLED of each pixel can be reduced.
As described above, the peak brightness of the display device can be changed according to the APL and the PLC curve of the input image. When the APL of the partial image 6210 displayed by the first display device 100_1 is 15% and the APL of the remaining video 6230 displayed by the second display device 100_2 is 60%, the peak luminance As shown in FIG. 63, a difference in brightness of each image occurs. This reduces the effect of viewing a single screen through the two display devices, which greatly hinders the user's viewing.
In order to solve such a problem, a method of setting the brightness of a part of the content to be displayed on the first display device 100_1 and the remaining images of the content to be displayed on the second display device 100_2 will be described in the following .
65 is a view for explaining another configuration of a control unit for controlling the brightness of each display apparatus according to an embodiment of the present invention.
In FIG. 65, the controller 170 is assumed to be included in the first display device 100_1. However, the present invention is not limited thereto and may be included in the second display device 100_2.
65, the control unit 170 may include an image frame division unit 6510, an APL calculation unit 6530, and a luminance control unit 6550.
The controller 170 can transmit and receive data to and from the timing controller 6570. The timing controller 6570 may be included in the controller 170.
The image frame dividing unit 6510 can divide an image frame input from the outside into a left image frame and a right image frame. The left image frame may be a frame to be displayed on the first display device 100_1, and the right image frame may be a frame to be displayed on the second display device 100_2. The image frame dividing unit 6510 may correspond to the configuration of the frame trimming unit 176_1 illustrated in FIG.
The APL calculation unit 6530 can calculate the APL of the left image frame and the APL of the right image frame. The APL may be an average luminance value for pixel data of one frame. The higher the APL, the brighter the image, and the lower the APL, the darker the image. The APL calculation unit 6530 can transmit the APL of the left image frame, the APL of the right image frame, and the PLC curve data to the luminance controller 6550. The PLC curve data may include data indicating a correspondence relationship between APL and peak luminance as a curve. The APL calculation unit 6530 can transmit the PLC curve data previously stored in the storage unit 140 (see FIG. 1) to the luminance control unit 6550. The PLC curve data may include only data for each of a specific number (eight) of the PLC points P0 to P7, as shown in FIG. 63, in order to reduce the amount of data operation.
The luminance controller 6550 controls the first display device 100_1 and the second display device 100_2 based on the first APL value of the left image frame and the second APL value of the right image frame received from the APL calculation unit 6530, The brightness of any one of them can be adjusted. Controlling the brightness may indicate controlling the brightness of the pixels constituting each display device.
The luminance controller 6550 can adjust the luminance of either the first display device 100_1 or the second display device 100_2 depending on whether the difference between the first APL value and the second APL value is equal to or greater than a threshold value.
The luminance controller 6550 can control the peak luminance so that the brightness of the partial image of the content to be displayed on the first display device 100_1 and the remaining image of the content to be displayed on the second display device 100_2 are equalized. This will be described in detail later.
The timing controller 6570 can receive pixel data of the input image, PLC curve data, and timing signals. The timing controller 6570 can modulate the gradation of the pixel data so that the luminance of the input image is limited below the peak luminance defined by the PLC curve. The timing controller 6570 generates a timing control signal for controlling the operation timing of the data driving circuit and the gate driving circuit based on the timing signal received together with the pixel data of the input image. The timing signal input to the timing controller 6570 may include a vertical synchronization signal, a horizontal synchronization signal, a main clock signal, a data enable signal, and the like.
The timing controller 6570 can adjust the brightness of the display device based on the PLC curve data. Accordingly, the current flowing in the OLDE of the pixel can be lowered.
FIG. 66 is a flowchart illustrating an operation method of a display apparatus according to another embodiment of the present invention.
Fig. 66 exemplifies the case where the first display device 100_1 sets the peak luminance control curve, but the present invention is not limited thereto, and the second display device 100_2 may set the peak luminance control curve.
Referring to FIG. 66, the controller 170 of the first display device 100_1 obtains an image frame of content input from the outside (S6501). In one embodiment, the controller 170 may receive an image frame of content from the distributor 171 described in FIG. In another embodiment, the control unit 170 may receive an image frame of the content through the external device interface unit 135. [
The control unit 170 may divide the image of the content input from the outside into a plurality of image frames. Each of the plurality of image frames may be a unit frame constituting an image of the content.
The controller 170 of the first display device 100_1 divides the acquired image frame into a left image frame and a right image frame (S6503). In one embodiment, the left image frame may be a frame to be displayed through the first display device 100_1, and the right image frame may be a frame to be displayed through the second display device 100_2, or vice versa.
The image frame dividing unit 6510 of the control unit 170 may divide the input image into a plurality of image frames.
The controller 170 of the first display device 100_1 calculates the first APL value of the divided left image frame and the second APL value of the right image frame (S6505). The controller 170 may calculate the first APL value corresponding to the left image frame and the second APL value corresponding to the right image frame through Equation 1 described in FIG.
In one embodiment, the controller 170 may calculate the APL for two image frames at 30 ms time intervals, but this is only an example.
The controller 170 of the first display device 100_1 checks whether the difference between the first APL value and the second APL value is equal to or greater than a threshold value (S6507). In one embodiment, the threshold may be a value that is a reference for changing the first peak luminance control mode (first PLC mode) to the second peak control mode (second PLC control mode). The threshold value may have a certain numerical range. For example, the threshold can be in the range of 40 to 50, but this is only an example.
The first peak luminance control mode (the first PLC mode) may be a mode for controlling the peak luminance using the default PLC curve described in FIG. Each of the first display device 100_1 and the second display device 100_2 can basically operate in the first PLC mode.
The second peak luminance control mode (second PLC mode) is a mode in which the brightness of the partial image of the content to be displayed on the first display device 100_1 is equal to the brightness of the remaining image of the content to be displayed on the second display device 100_2 As shown in FIG. In one embodiment, the second PLC mode may be a mode for controlling the peak brightness based on the larger of the first APL value and the second APL value. This will be described later.
The controller 170 of the first display device 100_1 determines the operation mode of the first display device 100_1 and the second display device 100_2 when the difference between the first APL value and the second APL value is less than the threshold value The first PLC mode is set (S6509). The first PLC mode may be a mode for controlling the peak luminance according to the APL through the PLC curve described in FIG. If the difference between the first APL value and the second APL value is less than the threshold value, It can be judged that the difference in brightness between the left image frame and the right image frame does not largely occur. The controller 170 can control the brightness of the screen of each display device according to the PLC curve set as the default. If the difference between the first APL value and the second APL value is less than the threshold value, the control unit 170 may transmit an instruction to the second display device 100_2 to operate in the first PLC mode.
In one embodiment, each of the first display device 100_1 and the second display device 100_2 may be in the first PLC mode before step S6501.
The control unit 170 of the first display device 100_1 determines the operation mode of the first display device 100_1 and the second display device 100_2 when the difference between the first APL value and the second APL value is equal to or greater than the threshold value The second PLC mode is set (S6511). The second PLC mode may be a mode for controlling the peak luminance so that the brightness between the partial image of the content to be displayed on the first display device 100_1 and the remaining image of the content to be displayed on the second display device 100_2 is equalized. Specifically, the second PLC mode may be a mode for controlling the brightness of each display device based on any one of the first APL value and the second APL value. This will be described with reference to FIG.
67 is a flowchart specifically illustrating a process of setting a second PLC mode according to an embodiment of the present invention.
67, if the difference between the first APL value and the second APL value is equal to or greater than the threshold value, the controller 170 acquires the first APL value and the second APL value as the reference APL value (S6601 ). In one embodiment, the controller 170 may select a larger value among the first APL value and the second APL value as the reference APL value. For example, when the first APL value of the left image frame is 15% and the second APL value of the right image frame is 60%, the controller 170 can confirm that the difference in the APL value is equal to or greater than the threshold value, The second APL value (60%) corresponding to the frame can be selected as the reference APL value.
The reason why the larger APL value is selected as the reference APL value is that the smaller the APL value, the higher the corresponding peak brightness and the higher the power consumption, as shown in FIG.
The controller 170 changes the peak luminance of either the first display device 100_1 or the second display device 100_2 based on the obtained reference APL value (S6603). In one embodiment, the controller 170 may change the PLC curve applied to any one of the two display devices to have a constant luminance corresponding to the obtained reference APL value. If the obtained reference APL value is 60% and the luminance value corresponding to 60% is 175 as described above, the controller 170 controls the first display device 100_1 so that the peak luminance of the left image frame is 175 ) Can be adjusted. In one embodiment, the controller 170 may change the predetermined default PLC curve to a horizontal PLC curve in order to set the luminance value of the left image frame to 175. [ The horizontal PLC curve may be a curve used to make the luminance of the left image frame the same as the right image frame. This will be described with reference to FIGS. 68 to 69. FIG.
68 to 69 are views for explaining an example of controlling the brightness of the first display device by adjusting the PLC curve according to the reference APL.
In the PLC curves of Figs. 68 and 69, the digital luminance values are used for the vertical axis.
Figure 68 shows a default PLC curve 6800 that includes eight PLC points (P0 through P7). Assuming that the first APL value of the left image frame to be displayed on the first display device 100_1 is 15% and the second APL value of the right image frame to be displayed on the second display device 100_2 is 60%, the reference APL The value is 60% corresponding to the display device 100_2. The luminance value corresponding to the APL 15% is 255, and the luminance value corresponding to the APL 60% is 175. In FIG. 68, the PLC points corresponding to the APL 15% and the luminance value 255 are denoted by P9, the PLC points corresponding to the APL 60% and the luminance value 175 are denoted by P8.
Before the luminance is controlled according to the reference APL value (60%), each of the first display device 100_1 and the second display device 100_2 is in a state of controlling the luminance according to the default PLC curve 6800 shown in FIG. 63 . When the reference APL value is obtained, the control unit 170 can use the PLC points P0 to P7 to calculate the brightness corresponding to the reference APL value (60%). Specifically, the controller 170 may extract the PLC point P8 located between the PLC points P0 to P7 using a linear interpolation method. The controller 170 may calculate the luminance value 175 corresponding to the reference APL value (60%) using a linear interpolation method.
The control unit 170 may change the default PLC curve 6800 to the horizontal PLC curve 6910 as shown in Fig. 69 according to the calculated luminance value. The horizontal PLC curve 6910 may be a curve that keeps the peak luminance constant according to the APL. The horizontal PLC curve 6910 may include data on the luminance corresponding to the reference APL value.
That is, the controller 170 can adjust the luminance of the left image frame to the luminance corresponding to 60% of the APL.
Meanwhile, the controller 170 may adjust the brightness of the first display device 100_1 and the brightness of the second display device 100_2 within the range of 25% to 100% of the reference APL value. That is, the horizontal PLC curve can be moved between a horizontal PLC curve 6920 corresponding to APL 25% and a horizontal PLC curve 6930 corresponding to APL 100%.
According to the embodiment of the present invention, the controller 170 may compare the current luminance value with the target luminance value to prevent a flicker of the image, and sequentially adjust the current luminance value to reach the target luminance value . The flicker of the image is a phenomenon that the image flickers when the luminance is changed excessively. Assume that the current luminance value is 255 corresponding to APL 15% and the target luminance value is 175 corresponding to APL 60%. The controller 170 decreases the luminance by one and can adjust the current luminance value 255 to the target luminance value 175. [
According to another embodiment of the present invention, the luminance of the first display device 100_2 may be adjusted according to a user input. That is, the first display device 100_1 can display an interface screen for adjusting the brightness, and can adjust the PLC curve according to a command input through the interface screen. The interface screen for adjusting the luminance changes the APL value of a part of the content displayed on the first display device 100_1, the APL value of the remaining image of the content displayed on the second display device 100_2, and the PLC curve of each display device And a PLC curve adjustment input window for setting the PLC curve. The user can confirm the APL value of the image displayed on each display device and adjust the PLC curve set in any one of the display devices through user input.
According to various embodiments of the present invention, the PLC curve of the display device is adjusted according to the reference APL value so that the brightness of the left image frame can be the same as the brightness of the right image frame, and the user feels inconvenience .
