Description

Display device and brightness control method thereof

The present invention relates to a display device and a brightness control method thereof, and more particularly, to a method of controlling the brightness of each display device when implementing a large screen through two display devices.

Recently, various types of display devices have emerged. Among them, organic light emitting diode displays (hereinafter, referred to as "OLED display devices") are frequently used. Since the OLED display is a self-light emitting device, there is an advantage in that power consumption is lower and thinner than the liquid crystal display which requires a backlight. In addition, the OLED display device has a wide viewing angle and a fast response speed.

In addition, recently, a lot of services that provide an image of a content by combining OLED displays have emerged. That is, only one display device is limited in the size of the screen, and a large screen is implemented through several display devices to provide an image of content.

However, when a plurality of display apparatuses are attached to provide an image of content, the average image level of some images input to the timing controller of each display apparatus and the average image level of the remaining images may vary. Luminance and luminance of the remaining images may be different. That is, a difference in brightness of an image input to each display device may occur, which may interfere with user's viewing.

An object of the present invention is to adjust the brightness of each display device in order to eliminate the difference in brightness of an image input to each display device when displaying the same content through a plurality of display devices.

A brightness control method of a first display device which is connected to a second display device that displays a partial image of content according to an embodiment of the present invention and displays the remaining image of the content comprises: receiving an entire image of the content; Acquiring a first APL (Average Picture Level) value of some images and a second APL value of the remaining images, and based on a difference between the obtained first APL value and the second APL value; And adjusting the luminance of any one of the second display devices.

According to an embodiment of the present disclosure, a first display apparatus connected to a second display apparatus displaying a partial image of content may include a display unit displaying the remaining image of the content and a partial image of the entire image of the content input from the outside. Obtaining a first APL (Average Picture Level) value and a second APL value of the remaining image, and based on the difference between the obtained first APL value and the second APL value, the first display device and the first APL value; The luminance of any one of the two display apparatuses may be adjusted.

If the difference between the first APL value and the second APL value is greater than or equal to a threshold value, the controller is configured to display the first display device and the second display device at a luminance corresponding to a larger value of the first APL value and the second APL value. The luminance of any one of the display devices may be adjusted.

The controller may adjust the luminance by changing a default PLC (Peak Luminance Control) curve that defines the maximum luminance of the pixels according to APL to a horizontal PLC curve defined to have a constant luminance value according to the APL. It may be a luminance value corresponding to a larger value of the first APL value and the second APL value.

The controller may acquire a luminance value corresponding to a larger value of the first APL value and the second APL value by using a plurality of PLC points obtained by equally dividing the default PLC curve.

When the second APL value is larger than the first APL value, the controller may sequentially change the luminance value corresponding to the first APL value to adjust the luminance value corresponding to the second APL value.

The threshold value is a difference between the first APL value and the second APL value, which are used as a reference for adjusting the luminance of any one of the first display device and the second display device, and may have a range of 40 to 50.

The controller may adjust the luminance by changing a default PLC (Peak Luminance Control) curve that defines the maximum luminance of pixels according to the APL into a horizontal PLC curve having a constant luminance value according to a user command.

According to various embodiments of the present disclosure, a merge screen for displaying one image on a large screen may be easily implemented using a plurality of display devices.

In addition, the present invention allows a user to easily manipulate various operations performed by interlocking screens of a plurality of display apparatuses.

According to various embodiments of the present disclosure, as the screens of the plurality of display devices are linked to each other, the user may have an effect as if the user views content through one display device.

In addition, the competitiveness of the large screen may be enhanced by taking advantage of the thin bezel and the black area of each display device.

In addition, when dividing and displaying the same content through a plurality of display devices, as the brightness of each display device is adjusted, the brightness difference of the image input to each display device is reduced, so that the user who wants to watch the content through the large screen is displayed. You can maximize your satisfaction.

The time synchronization units 177_1 and 177_2 may synchronize the reproduction of each frame by using an 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, the time synchronization units 177_1 and 177_2 may output the corresponding frames to the display units 180. Accordingly, the timing of each frame is corrected, and as shown in FIG. 17D, an image of content may be displayed on one large screen.

Next, an embodiment in which the arrangement of each device is automatically or manually set for normal interworking between the screen of the first display device 100_1 and the screen of the second display device 100_2 will be described.

FIG. 18A illustrates a state in which the first display device 100_1 and the second display device 100_2 are normally disposed, and FIG. 18B illustrates the first display device 100_1 and the second display device ( 100_2) is abnormally disposed. That is, it is assumed that the first display apparatus 100_1 is disposed at the left side and the second display apparatus 100_2 is disposed at the right side in a normal arrangement.

When the first display device 100_1 and the second display device 100_2 are abnormally arranged, screen interlocking is also abnormally performed, and as shown in FIG. 18B, content playback is performed on one large screen. May not be displayed smoothly.

Referring to FIG. 19, each of the first display apparatus 100_1 and the second display apparatus 100_2 may display a plurality of batch setting items for batch setting. The plurality of arrangement setting items may include a left arrangement setting item 710 and a right arrangement setting item 720. When the left arrangement setting item 710 displayed on the screen of the first display apparatus 100_1 is selected through a button input of the remote control apparatus 200, the first display apparatus 100_1 may be set to be arranged on the left side. have. When the right arrangement setting item 730 is selected through the button input of the remote control apparatus 200 on the screen of the second display apparatus 100_2, the second display apparatus 100_2 may be set to be disposed on the right side. .

According to an embodiment, the arrangement setting item may be displayed when each display apparatus 100 enters the twin mode.

Referring to FIG. 20, the first display apparatus 100_1 may include a first left speaker 185_1 and a first right speaker 185_2, and the second display apparatus 100_2 may include a second left speaker 185_3. And a second right speaker 185_4. The remote control apparatus 200 may be positioned in front of the first display apparatus 100_1 and the second display apparatus 100_2, and the first display apparatus 100_1 and the second display apparatus 100_2 may be in close contact with each other. Assume

The control unit 170 of each display apparatus 100 may sequentially output a test voice signal through the provided speaker. For example, the test voice signal may be output 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 strength of each test speech signal may be the same.

The microphone 291 of the remote control apparatus 200 may receive a test voice signal output from each speaker. The controller 280 of the remote control apparatus 200 may calculate a gain of each test voice signal based on the received test voice signal. For example, the gain G1 of the test voice signal output from the first left speaker 185_1 and the test voice signal output from the second right speaker 185_4 due to the distance difference between each speaker and the remote control apparatus 200. One of the gains G4 may be the highest gain and the other may be the lowest gain. In addition, since the first display apparatus 100_1 and the second display apparatus 100_2 are in close contact with each other, the gain G2 and the second left speaker 185_3 of the test voice signal output from the first right speaker 185_2 are output. The magnitude of the gain G3 of the tested test speech signal may be similar. The first display apparatus 100_1 may receive the gain of each test voice signal from the remote control apparatus 200, and may determine its own position and the position of the second display apparatus 100_2 based on the received gain. . For example, when the remote control apparatus 200 is located closest to the first left speaker 185_1, the test voice signal output from the first left speaker 185_1 has the largest magnitude, and the second right speaker ( The test voice signal output from 185_4 may be the smallest. Each of the first display apparatus 100_1 and the second display apparatus 100_2 recognizes a location of the provided speaker. Accordingly, since the test voice signal output from the first left speaker 185_1 has the largest magnitude, the first display apparatus 100_1 may recognize that the first display apparatus 100_1 is disposed on the left side of the second display apparatus 100_2. Since the test voice signal output from the speaker 185_4 is the smallest, it may be recognized that the second display apparatus 100_2 is disposed on the right side of the first display apparatus 100_2. In this case, the first display apparatus 100_1 may check that the arrangement of each display apparatus 100 is normal. If the first display apparatus 100_1 has an abnormal arrangement of each display apparatus 100, as shown in FIG. 22 to be described later, the first display apparatus 100_1 may display the screen arrangement guide window 731.

Description of the above-described input key is an example for description and is not limited thereto. Therefore, various keys may be displayed on the input key according to a user's or designer's selection.

Next, when some of the image of the content is displayed on the first display device 100_1 and the remaining image of the content is displayed on the second display device 100_2 according to another embodiment of the present invention (ie, a twin Mode, the brightness of each image is changed as the average picture level (APL) of some images and the APL of the remaining images are different from each other.

First, referring to FIG. 62, the first display apparatus 100_1 displays some images 6210 of the entire image of the content, and the second display apparatus 100_2 displays the remaining images 6230 among the entire images of the content. It is displaying.

As illustrated in FIG. 62, the brightness of the partial image 6210 of the content displayed by the first display apparatus 100_1 is higher than the brightness of the remaining image 6230 of the content displayed by the second display apparatus 100_2. . This is because an average picture level (APL) of an image input to each display device is changed so that a peak luminance corresponding thereto 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 the power consumption. However, simply lowering the brightness may lower power consumption, but the image quality may deteriorate. For example, when the user lowers the luminance of the display image, the luminance may be excessively lowered in a bright image having a high APL. The APL may be defined as an average of luminance of the brightest colors in one image frame, and may be represented by Equation 1 below.

[Equation 1]

Here, R means red data, G means green data, and B means blue data. Max (R, G, B) is the maximum of R, G, and B, and SUM {Max (R, G, B)} is the sum of the maximum of R, G, and B. An image having a large number of bright pixel data has a high average image level (APL). On the other hand, an image having a small number of bright pixel data has a low average image level (APL).

The relationship between APL and Peak Luminance Control (PLC) is discussed.

FIG. 63 is a graph illustrating a PLC curve for controlling luminance according to APL, and FIG. 4 is a diagram illustrating a state in which luminance values corresponding to each of the plurality of PLC points constituting the PLC curve are converted into digital values.

Hereinafter, luminance when APL = 25% is called peak luminance, and luminance of APL = 100% is called full white luminance. Peak luminance is higher because of the lower load on the screen compared to full white luminance. In the case of OLED displays, more current flows into the OLEDs of the pixels at peak luminance, emitting light brighter than full white luminance. Peak Luminance Control (PLC) method (hereinafter referred to as "PLC control method") lowers power consumption by lowering luminance as APL increases based on a PLC curve.

The PLC curve, shown in FIG. 63, defines the maximum luminance of the pixel. The pixels of the display panel emit light below the maximum luminance limited by the PLC curve. The PLC curve defines the luminance values according to APL so that the maximum luminance of the pixels is increased to the peak luminance level at low APL, while the maximum luminance of the pixels is lowered at higher APL. The data including information on the PLC curve may include only data for a certain number of PLC points P0 to P7 in order to reduce the amount of computation of the data. Each PLC point may be a point located at a boundary between neighboring sections when the PLC curve is equally divided into N sections. Each PLC point may represent a corresponding point between APL and peak luminance. 64 shows an example in which the number of PLC points is eight. Referring to FIG. 4, digital luminance values corresponding to each of the eight PLC points P0 to P7 are illustrated.

The timing controller (T-con), which will be described later, may lower the brightness of the display device based on the PLC curve, and thus the current flowing through the OLED of each pixel may be reduced.

As such, the display apparatus may have a peak luminance that varies according to the APL and PLC curves of the input image. When the APL of the partial image 6210 displayed by the first display apparatus 100_1 is 15% and the APL of the remaining image 6230 displayed by the second display apparatus 100_2 is 60%, the peak luminance is accordingly 63, the difference in brightness of each image occurs. This reduces the effect of viewing one screen through two display devices, which greatly disturbs the user's viewing.

Hereinafter, to solve this problem, a method of setting the same brightness between the partial image of the content to be displayed on the first display apparatus 100_1 and the remaining image of the content to be displayed on the second display apparatus 100_2 will be described. .

In FIG. 65, the controller 170 is described on the premise that the configuration is included in the first display apparatus 100_1. However, the controller 170 is not limited thereto and may be a configuration included in the second display apparatus 100_2.

Referring to FIG. 65, the controller 170 may include an image frame divider 6510, an APL calculator 6630, and a luminance controller 6550.

The controller 170 may exchange data with the timing controller 6708. The timing controller 6050 may be a component included in the controller 170.

The image frame dividing unit 6510 may divide the 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 apparatus 100_1, and the right image frame may be a frame to be displayed on the second display apparatus 100_2. The image frame dividing unit 6510 may correspond to the configuration of the frame cutting unit 176_1 described with reference to FIG. 16.

The APL calculator 6530 may 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 calculator 6530 may transfer the calculated APL of the left image frame, APL of the right image frame, and PLC curve data to the luminance controller 6550. The PLC curve data may include data representing a correspondence relationship between the APL and the peak luminance. The APL calculator 6530 may transmit the PLC curve data pre-stored in the storage 140 (see FIG. 1) to the luminance controller 6550. PLC curve data may include only data for each of a specific number (eight) of the PLC points (P0 to P7), as shown in Figure 63 in order to reduce the amount of calculation of the data.

The luminance controller 6550 is 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 calculator 6630, and the first display apparatus 100_1 and the second display apparatus 100_2. Any one of the brightness can be adjusted. Controlling the luminance may refer to controlling the luminance of the pixels constituting each display device.

The luminance controller 6550 may adjust the luminance of any one of the first display apparatus 100_1 and the second display apparatus 100_2 according to whether the difference between the first APL value and the second APL value is greater than or equal to a threshold value.

The luminance controller 6550 may control the peak luminance to equalize 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. This will be described later in detail.

The timing controller 6708 may receive pixel data, PLC curve data, and timing signals of an input image. The timing controller 6708 may modulate the gray level of the pixel data such that the luminance of the input image is limited to be equal to or less than the peak luminance defined by the PLC curve. The timing controller 6708 also 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 6050 may include a vertical synchronization signal, a horizontal synchronization signal, a main clock signal, a data enable signal, and the like.

The timing controller 6708 may adjust the brightness of the display device based on the PLC curve data. As a result, the current flowing in the OLDE of the pixel may be lowered.

66 illustrates an example in which the first display apparatus 100_1 sets the peak luminance control curve. However, the present invention is not limited thereto, and the second display apparatus 100_2 may set the peak luminance control curve.

Referring to FIG. 66, the controller 170 of the first display apparatus 100_1 obtains an image frame of content input from the outside (S6501). According to an embodiment, the controller 170 may receive an image frame of content from the distributor 171 described in FIG. 1. In another embodiment, the controller 170 may receive an image frame of content through the external device interface 135.

The controller 170 may divide an image of 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 content.

The controller 170 of the first display apparatus 100_1 divides the obtained image frame into a left image frame and a right image frame (S6503). According to an 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 controller 170 may divide the input image into a plurality of image frames.

The controller 170 of the first display apparatus 100_1 calculates a first APL value of the divided left image frame and a 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 with reference to FIG. 64.

According to an embodiment, the controller 170 may calculate APL for two image frames at 30 ms time intervals, but this is only an example.

The controller 170 of the first display apparatus 100_1 checks whether a difference between the first APL value and the second APL value is greater than or equal to a threshold value (S6507). In an embodiment, the threshold value may be a reference value for changing the first peak luminance control mode (first PLC mode) to the second peak control mode (second PLC control mode). The threshold may have a specific numerical range. For example, the threshold may be in the range between 40 and 50, but this is only an example.

The first peak luminance control mode (Peak Luminance Control mode, 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 apparatus 100_1 and the second display apparatus 100_2 may basically operate in the first PLC mode.

In the second peak luminance control mode (second PLC mode), the peak luminance is set to equalize the brightness between the partial image of the content to be displayed on the first display apparatus 100_1 and the remaining image of the content to be displayed on the second display apparatus 100_2. It may be a mode for controlling. According to an embodiment, the second PLC mode may be a mode for controlling peak luminance based on a larger value of the first APL value and the second APL value. This will be described later.

When the difference between the first APL value and the second APL value is less than the threshold value, the controller 170 of the first display apparatus 100_1 may select an operation mode of the first display apparatus 100_1 and the second display apparatus 100_2. Set to the first PLC mode (S6509). The first PLC mode may be a mode for controlling peak luminance according to APL through the PLC curve described in FIG. 63. When the difference between the first APL value and the second APL value is less than the threshold value, the controller 170 may determine that the difference in brightness between the left image frame and the right image frame does not occur significantly. The controller 170 may control the brightness of the screen of each display device according to the PLC curve set as a default. When the difference between the first APL value and the second APL value is less than the threshold value, the controller 170 may transmit a command to the second display apparatus 100_2 to operate in the first PLC mode.

According to an exemplary embodiment, each of the first display device 100_1 and the second display device 100_2 may be operating in the first PLC mode before step S6501.

When the difference between the first APL value and the second APL value is greater than or equal to the threshold value, the controller 170 of the first display apparatus 100_1 may determine the operation modes of the first display apparatus 100_1 and the second display apparatus 100_2. Set to the second PLC mode (S6511). The second PLC mode may be a mode in which the peak luminance is controlled to equalize 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. In detail, the second PLC mode may be a mode for controlling the brightness of each display device based on one of the first APL value and the second APL value. This will be described with reference to FIG. 67.

Referring to FIG. 67, when the difference between the first APL value and the second APL value is greater than or equal to the threshold value, the controller 170 obtains one of the first APL value and the second APL value as the reference APL value (S6601). ). According to an 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 may determine that the difference between the APL values is greater than or equal to a threshold value and the right image. The second APL value (60%) corresponding to the frame may be selected as the reference APL value.

The reason why the value of the larger APL value is selected as the reference APL value is that, as shown in FIG. 63, the smaller the APL value, the higher the corresponding peak luminance may be and power consumption may increase.

The controller 170 changes the peak luminance of any one of the first display apparatus 100_1 and the second display apparatus 100_2 based on the obtained reference APL value (S6603). According to an embodiment, the controller 170 may change the PLC curve applied to any one of the two display apparatuses so as to have a constant luminance corresponding to the obtained reference APL value. As an example, when the obtained reference APL value is 60% and the luminance value corresponding to 60% is 175, the controller 170 may display the first display apparatus 100_1 such that the peak luminance of the left image frame is 175. You can adjust the PLC curve applied to). According to an embodiment, the controller 170 may change the preset default PLC curve into a horizontal PLC curve to set the luminance value of the left image frame to 175. FIG. The horizontal PLC curve may be a curve used for equalizing the luminance of the left image frame with the right image frame. This will be described with reference to FIGS. 68 to 69.

In the PLC curves of FIGS. 68 and 69, the vertical axis used digital luminance values.

68 shows a default PLC curve 6800 that includes eight PLC points P0 to 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 first display device 100_2. Assume that the luminance value corresponding to APL 15% is 255 and the luminance value corresponding to APL 60% is 175. In FIG. 68, a PLC point corresponding to APL 15% and luminance value 255 is P9, and a PLC point corresponding to APL 60% and luminance value 175 is P8.

Before the luminance is controlled according to the reference APL value (60%), each of the first display apparatus 100_1 and the second display apparatus 100_2 is in a state in which the luminance is controlled according to the default PLC curve 6800 shown in FIG. 63. Is in. When the reference APL value is obtained, the controller 170 may use the PLC points P0 to P7 to calculate the luminance corresponding to the reference APL value (60%). In detail, the controller 170 may extract the PLC point P8 located between the PLC points P0 to P7 by using a linear interpolation method. The controller 170 may calculate a luminance value 175 corresponding to the reference APL value (60%) by using a linear interpolation method.

As illustrated in FIG. 69, the controller 170 may change the default PLC curve 6800 to the horizontal PLC curve 6910 according to the calculated luminance value. The horizontal PLC curve 6910 may be a curve that makes the peak luminance constant according to the APL. The horizontal PLC curve 6910 may include data about luminance corresponding to the reference APL value.

That is, the controller 170 may adjust the luminance of the left image frame to the luminance corresponding to 60% of the APL.

The controller 170 may adjust one of the luminance of the first display apparatus 100_1 and the luminance of the second display apparatus 100_2 within a range of 25% to 100% of the reference APL value. That is, the horizontal PLC curve may be moved between the horizontal PLC curve 6920 corresponding to APL 25% and the horizontal PLC curve 6930 corresponding to APL 100%.

According to an embodiment of the present disclosure, the controller 170 may compare the current luminance value with the target luminance value to prevent flicker of the image, and sequentially adjust the current luminance value to reach the target luminance value. Can be. Image flickering is a phenomenon in which the image flickers when the brightness 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 adjusts the current luminance value 255 to the target luminance value 175.

According to another embodiment of the present disclosure, the luminance of the first display apparatus 100_2 may be adjusted according to a user input. That is, the first display apparatus 100_1 may display an interface screen for adjusting the brightness and may adjust the PLC curve according to a command input through the interface screen. The interface screen for adjusting the brightness changes the APL value of some images of the content displayed on the first display device 100_1, the APL value of the remaining images of the content displayed on the second display device 100_2, and the PLC curve of each display device. It can include a PLC curve adjustment input window. A user may check an APL value of an image displayed by each display device and adjust a PLC curve set in any one display device through a user input.

According to various embodiments of the present disclosure, the PLC curve of the display apparatus may be adjusted according to the reference APL value, such that the brightness of the left image frame may be the same as the brightness of the right image frame, and the user may not feel inconvenience in viewing the image. You may not.

Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The display device described above may not be limitedly applied to the configuration and method of the above-described embodiments, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications may be made. It may be.
