     Hereinafter, embodiments will be described in greater detail with reference to the drawings. 
     The terms used in the disclosure and the claims are general terms identified in consideration of the functions of embodiments. However, these terms may vary depending on intention, legal or technical interpretation, emergence of new technologies, and the like of those skilled in the related art. In addition, in some cases, a term may be selected by the applicant, in which case the term will be described in detail in the description of the corresponding disclosure. Thus, the term used in this disclosure should be defined based on the meaning of term, not a simple name of the term, and the contents throughout this disclosure. 
     In this disclosure, the expressions “have,” “may have,” “include,” or “may include” or the like represent presence of a corresponding feature (for example: components such as numbers, functions, operations, or parts) and does not exclude the presence of additional feature. 
     Expressions such as “at least one of,” and “at least one from among,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. For example, the expression, “at least one from among a, b, and c,” should be understood as including only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c. 
     In the disclosure, the terms “1st” or “first” and “2nd” or “second” may use corresponding components regardless of importance or order and are used to distinguish one component from another without limiting the components. 
     In addition, the description in the disclosure that one element (e.g., a first element) is “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element) should be interpreted to include both the case that the one element is directly coupled to the another element, and the case that the one element is coupled to the another element through still another intervening element (e.g., a third element). 
     A singular expression includes a plural expression, unless otherwise specified. It is to be understood that the terms such as “comprise” or “consist of” are used herein to designate a presence of a characteristic, number, step, operation, element, component, or a combination thereof, and not to preclude a presence or a possibility of adding one or more of other characteristics, numbers, steps, operations, elements, components or a combination thereof. 
     The term such as “module,” “unit,” “part,” and so on may be used to refer to an element that performs at least one function or operation, and such element may be implemented as hardware or software, or a combination of hardware and software. Further, except for when each of a plurality of “modules,” “units,” “parts,” and the like needs to be realized in an individual hardware, the components may be integrated in at least one module or chip and be realized in at least one processor.

     Hereinafter, various example embodiments will be described in greater detail with reference to the accompanying drawings. 
       FIG.  1    is a diagram illustrating a multi-view mode according to an embodiment. 
     As illustrated in  FIG.  1   , the display apparatus  100  may be implemented as a television (TV), but is not limited thereto, and may be applicable to any device having a display function such as a video wall, a large format display (LFD), a digital signage, and a digital information display (DID), a projector display, or the like. In addition, the display apparatus  100  may be implemented as various types displays, such as a liquid crystal display (LCD), an organic light-emitting diode (OLED), a liquid crystal on silicon (LCoS), a digital light processing (DLP), a quantum dot (QD) display panel, a quantum dot light-emitting diodes (QLED), micro light-emitting diodes (μLED), mini LED, or the like. The display apparatus  100  may be implemented as a touch screen coupled with a touch sensor, a flexible display, a rollable display, a three-dimensional (3D) display, a display in which a plurality of display modules are physically connected, or the like. 
     The display apparatus  100  may receive content from each of a plurality of source devices, and as illustrated in  FIG.  1   , may display a plurality of contents at the same time. 
     For example, the display apparatus  100  may provide a picture in picture (PIP) mode, a picture by picture (PBP) mode, or the like. For example, according to the PIP mode, the display apparatus  100  may display first content 1 received from a first source device  200 - 1  on a full screen, and overlay second content 2 received from a second source device  200 - 2  on one region within the full screen on which the first content 1 is displayed. Here, the position and size of the one region may be fixed, or the position and size of the one region may be adjusted according to a user command or the like. 
     As another example, according to the PBP mode, the display apparatus  100  may display the first content 1 received from the first source device  200 - 1  in one region within the full screen and display the second content 2 received from the second source device  200 - 2  in a remaining region within the full screen. Here, the position and size of the one region and the remaining region may be fixed, or may be adjusted according to a user command, content, or the like. 
     Hereinafter, a mode in which the display apparatus  100  displays a plurality of contents in a full screen such as the PIP mode and PBP mode will be referred to as a multi-view mode. 
     Referring to  FIG.  1   , for convenience of description, the display apparatus  100  may divide a full screen into four different regions in which four display contents are displayed, but this is provided as an example, and embodiments are not limited thereto. 
     For example, the display apparatus  100  may divide a full screen in two and may display content on each of two different regions. 
     The size (or ratio) of the different regions may be the same or different. 
     Referring to  FIG.  1   , the display apparatus  100  may receive content from each of the plurality of source devices  200 . For example, when the display apparatus  100  performs communication with n (n is a natural number) source devices  200  to receive content, the display apparatus  100  may obtain and output frames including each of the content in each of the n different regions on the screen by dividing the full screen by n. 
     For example, the display apparatus  100  may position first content 1 received from a first source device  200 - 1  in a first region, position second content 2 received from a second source device  200 - 2  in a second region, position third content 3 received from a third source device  200 - 3  in the third region, and position fourth content 4 received from a fourth source device  200 - 4  in a fourth region to provide a frame in which each of the content received from the first to fourth source devices  200 - 1 , . . . ,  200 - 4  is included. 
     For convenience, the number of source devices  200  providing the contents and the number of different regions provided with the contents within the full screen are unified, but this is provided as an example, and embodiments are not limited thereto. For example, the display apparatus  100  may receive content from each of the four source devices  200  and divide the full screen into two to display the first content 1 and the second content 2 in each of the two different regions. As another example, the display apparatus  100  may display the first content 1 and the fourth content 4 in each of the two different regions based on a user command or the like. 
     The plurality of source devices providing content to the display apparatus  100  each may have the same or different specification, format of provided content, size, resolution, contrast (e.g., high dynamic range (HDR) or standard dynamic range (SDR)), frame rate of content, or the like. 
     For example, the frame rate of the first content 1 received from the first source device  200 - 1  may be 60 Hz, and the frame rate of the second content 2 received from the second source device  200 - 2  may be 50 Hz. According to an embodiment, when the display apparatus  100  operates at one frame rate (e.g., 60 Hz), the display apparatus  100  may output each of the first content 1 and the second content 2 at 60 Hz. Accordingly, the frame rate of the second content 2 is 50 Hz, but the display apparatus  100  outputs the second content 2 at a frame rate of 60 Hz. 
     In a related multi-view mode for simultaneously providing a plurality of contents, a display apparatus changes a frame rate of each of a plurality of contents to a frame rate of the display apparatus, and then outputs a plurality of contents at the frame rate of the display apparatus, which causes several limitations in that the display apparatus fixes the content supporting variable refresh rate (VRR) to the frame rate of the display apparatus for outputting the content, and outputs a plurality of contents at a frame rate (e.g., frame rate of 60 Hz, if the maximum frame rate of the display apparatus is 120 Hz) lower than a maximum frame rate of the display apparatus. 
     For example, if the display apparatus operates at a maximum frame rate, the display apparatus may output a plurality of content after generating an interpolation frame using a motion estimation, motion compensation (ME/MC) such that each frame rate of the plurality of content corresponds to a maximum frame rate. In this case, the interpolation frame generated using ME/MC may generate an artifact, a distortion, an unnatural motion of an object in the content, and the like. 
     To address these issues, the display apparatus  100  according to an embodiment may concurrently provide each of a plurality of contents in a multi-view mode at different frame rates (e.g., frame rates of each of the plurality of contents). 
       FIG.  1    illustrates a case where each of a plurality of source devices  200  is identical or similar to each other for convenience of description, but this is provided as an example, and embodiments are not limited thereto. The source device  200  may be implemented with various kinds of electronic devices. For example, each of the plurality of source devices  200  may be implemented as various types of electronic devices that provide content such as Blu-Ray player, digital versatile disc (DVD) player, streaming content output device, set-top box, cloud server, over-the-top (OTT) media service server, personal computer (PC), video game console, etc. The display apparatus  100  may perform image processing according to various embodiments with respect to an image and output the image by itself, or may provide the image to another electronic device having a display. 
       FIG.  2    is a block diagram illustrating a configuration of a display apparatus according to an embodiment. 
     Referring to  FIG.  2   , the display apparatus  100  includes a communication interface  110 , a display  120 , and one or more processor  130 . 
     The communication interface  110  may receive various data. For example, the communication interface  110  may receive various data, for example, content from at least one source device  200 , external storage medium (e.g., USB memory), an external server (e.g., webhard) through a communication method such as AP-based wireless fidelity (WI-FI, wireless LAN network), a Bluetooth (BT), ZigBee, wired/wireless local area network (LAN), wide area network (WAN), IEEE 1394, high definition multimedia interface (HDMI), universal serial bus (USB), mobile high-definition link (MHL), advanced encryption standard (AES)/European broadcasting union (EBU), optical, and coaxial. 
     The communication interface  110  according to an embodiment may receive content by performing wired or wireless communication with each of the plurality of source devices  200 . 
     The display  120  may be implemented as a display including a self-emitting element or a display including a non-self-limiting element and a backlight. For example, the display  120  may be implemented as a display of various types such as, for example, and without limitation, a liquid crystal display (LCD), organic light emitting diodes (OLED) display, light emitting diodes (LED), micro LED, mini LED, plasma display panel (PDP), quantum dot (QD) display, quantum dot light-emitting diodes (QLED), or the like. In the display  120 , a backlight unit, a driving circuit which may be implemented as an A-Si TFT, low temperature poly silicon (LTPS) TFT, organic TFT (OTFT), or the like, may be included as well. The display  120  may be implemented as a touch screen coupled to a touch sensor, a flexible display, a rollable display, a third-dimensional (3D) display, a display in which a plurality of display modules are physically connected, or the like. 
     The one or more processor  130  according to an embodiment control overall operations of the display apparatus  100 . 
     The one or more processor  130  according to an embodiment may be implemented with, for example, and without limitation, a digital signal processor (DSP) for image-processing of a digital image signal, a microprocessor, a graphics processor (GPU), an artificial intelligence (AI) processor, a neural processor (NPU), a timing controller (T-CON), or the like, but the one or more processor are not limited thereto. The one or more processor  110  may include, for example, and without limitation, one or more among a central processor (CPU), a micro controller unit (MCU), a microprocessor (MPU), a controller, an application processor (AP), a communication processor (CP), an advanced reduced instruction set computing (RISC) machine (ARM) processor, a dedicated processor, or may be defined as a corresponding term. The one or more processor  130  may be implemented in a system on chip (SoC) type or a large scale integration (LSI) type which a processing algorithm is built therein, application specific integrated circuit (ASIC), or in a field programmable gate array (FPGA) type. The one or more processor  130  may perform various functions by executing computer executable instructions stored in a memory. 
     The one or more processor, when content is received from each of the plurality of source devices  200  through the communication interface in a multi-view mode, may obtain a frame including each of the content received at different regions. 
     A specific description will refer to  FIG.  3   . 
       FIG.  3    is a diagram illustrating a frame rate of each content according to an embodiment. 
     The display  120  according to an embodiment may be implemented to include a plurality of display modules  10 - 1  . . .  10 - n.    
     For example, as illustrated in  FIG.  3   , a plurality of display modules  10 - 1 , . . . ,  10 - n  may be coupled to implement one display apparatus (that is, display system). 
     Each of the plurality of display modules  10 - 1  and  10 - n  may include a plurality of self-emissive elements. Here, the self-emissive elements may be at least one of a light emitting diode (LED) or a micro LED. 
     In addition, each of the plurality of display modules  10 - 1 , . . .  10 - n  may be implemented as an LED cabinet including a plurality of light emitting diode (LED) elements. Each LED element may be implemented as an RGB LED, and the RGB LED may include a red LED, a green LED, and a blue LED. The LED elements may additionally include a white LED other than the RGB LED. 
     According to an example, the LED element may be implemented as a micro LED. The micro LED is an LED of a size of about 5-100 micrometers, and is a micro light-emitting element. The micro LED may emit light of a corresponding color (i.e., red, green, blue and white), and therefore may not require a color filter. 
     Each of the plurality of display modules  10 - 1 , . . . , and  10 - n  may include a timing controller (T-CON). The T-CON may include circuitry for adjusting the amount of data delivered/transmitted to a display driver integrated circuit (IC) (DDI). For example, the T-CON may convert the data signal received from the one or more processor  130  into a signal required by a gate IC and source IC of the DDI, and the DDI may drive each of the plurality of pixels included in the display module  10 . 
     According to an embodiment, the one or more processor  130  may provide each of the contents received from a plurality of source devices  200  through different regions on the display  120 . 
     For example, the one or more processor  130  may display the first content 1 received from the first source device  200 - 1  in the first region. The first region may include the first display module  10 - 1 . In this case, the one or more processor  130  may provide a data signal corresponding to the first content 1 to the T-CON corresponding to the first display module  10 - 1 . 
     As shown in  FIG.  3   , the one or more processor  130  may provide a data signal corresponding to the second content 2 to the T-CON corresponding to the second display module  10 - 2  included in the second region  20  to display the second content 2 received from the second source device  200 - 2  in the second region. 
     As illustrated in  FIG.  3   , the contents received from each of the plurality of source devices  200  may have different frame rates. 
     As illustrated above, the one or more processor  130  may adjust the frame rate of the display module  10  in order to maintain the frame rate of the content when outputting the content. 
     The frame rate of the display module may be referred to as a refresh rate, a frequency, or a scanning rate, but will hereinafter be referred to as a frame rate for convenience of description. The frame rate of the display module  10  may be expressed in a unit of Hz. For example, if the frame rate of the display module  10  is 60 Hz, the display module  10  may provide 60 frames per second. As another example, if the frame rate of the display module  10  is 120 Hz, the display module  10  may provide 120 frames per second. The example that the frame rate of the display module  10  is driven to 60 Hz and 120 Hz is provided as an example, and embodiments are not limited thereto. For example, the display module  10  may be driven at various frame rates such as 75 Hz, 120 Hz, 144 Hz, 240 Hz, etc. 
     Referring to  FIG.  3   , when content is received from each of the plurality of source devices  200  through the communication interface  110  in the multi-view mode, the one or more processor  130  may display the received content through different regions on the display  120 . 
     The one or more processor  130  according to an embodiment may identify the frame rate of the first content 1 displayed on the first region among different regions. 
     As an example, the image content (e.g., video) may refer to a set of temporally continuous still images, and one still image may be a frame. The frame rate of the image may be expressed in a unit of frames per second (FPS). The frame rate of the content may indicate the number of frames constituting the image for one second. The frame rate of an image may be referred to as a frame speed, a frame rate, but will hereinafter be referred to as a frame rate for convenience of description. 
     For example, if a content of at least 24 FPS is provided, the user may determine the corresponding content as a soft and smooth image. Generally, as the frame rate of the content increases, a user may feel that a soft and smooth image is provided, but embodiments are not limited thereto. 
     The display apparatus  100  according to various embodiments may receive and display content of various frame rates such as 60 FPS, 120 FPS, 1000 FPS, and the like, such as a game (e.g., first-person shooter game, racing game) content, sports content, and slow motion content, or the like. 
     The one or more processor  130  according to an embodiment may identify a frame rate of the first content 1 when the first content 1 is received from the first source device  200 - 1  through the communication interface  110 . As an example, a frame rate of an image (e.g., FPS of an image) may be identified based on metadata of the received content. The configuration that the one or more processor  130  identify the frame rate of the image based on the metadata of the content is provided as an example, and embodiments are not limited thereto. For example, the one or more processor  130  may identify the frame rate of the corresponding content based on the number of frames constituting the content for one second among the plurality of frames constituting the content. 
     The one or more processor  130  may then control the T-CON corresponding to the first display module  10 - 1  such that the first display module  10 - 1  included in the first region in which the first content 1 is displayed operates at the identified frame rate, i.e., the frame rate of the first content 1. 
     As an example, if the frame rate of the first content is a variable frame rate (VRR), the one or more processor  130  may control the T-CON of the first display module  10 - 1  such that the frame rate of the first display module  10 - 1  is variably changed in accordance with the frame rate of the first content. As another example, if the frame rate of the first content is 60 FPS, the one or more processor  130  may control the T-CON of the first display module  10 - 1  such that the first display module  10 - 1  included in the first region displaying the first content operates at a frame rate of 60 Hz corresponding to 60 FPS. 
     The frame rate (e.g., FPS unit) of content may indicate the number of frames constituting an image during one second, and the frame rate (e.g., Hz unit) of the display module  10  may indicate the number of frames provided by the display module  10  for one second. 
     As an example, if the frame rate of the content is low compared to the frame rate of the display module  10 , the display module  10  may repeatedly display some of the frames that make up the content, which may cause an image to appear to be slow to a user. 
     As another example, if the frame rate of the content is higher than the frame rate of the display module  10 , several new frames may be created before the display module  10  displays a next frame, which may cause some frames constituting the content to be lost or not be displayed 
     For convenience of description, only embodiments in which the frame rate of the first display module  10 - 1  is changed based on the first content 1 received from the first source device  200 - 1  have been described, but the embodiments are not limited thereto, and the one or more processor  130  may identify the frame rate of the contents received from each of the plurality of source devices  200 , and may control the corresponding T-CONs of the display modules  10  to operate at the identified frame rates corresponding to the different regions in which each of the plurality of content is displayed. 
     For convenience of description,  FIG.  3    has been described under the assumption that the first to fourth display modules  10 - 1 , . . . ,  10 - 4  constitute the display apparatus  100 , and that each of the four different contents is displayed in the first to fourth display modules  10 - 1 , . . . ,  10 - 4 , but this is provided as an example and embodiments are not limited thereto. Hereinafter, various configurations of the display apparatus  100  will be described. 
       FIG.  4    is a diagram illustrating a display module and a timing controller (T-CON) according to an embodiment. 
       FIG.  4    is a diagram illustrating a case in which the display apparatus  100  is composed of a total of eight display modules  10  and eight T-CONs, and each of the plurality of display modules  10 - 1 , . . . ,  10 - n  is implemented at a resolution of 960×1080. The T-CON of each of the plurality of display modules  10 - 1 , . . . ,  10 - n  may receive control signals, data signals, etc., from the one or more processor  130 . In this case, the display apparatus  100  may have a resolution of 3840×2160. This is provided as an example, and according to embodiments, the number of display modules  10  included by the display apparatus  100  may be variously changed, and resolution of the display apparatus  100  may also be variously changed as the resolution of each of the plurality of display modules  10 - 1 , . . . ,  10 - n  is variously changed. 
     According to one embodiment, processor  130  may transmit control signals, data signals, etc., corresponding to content received from the source device to a plurality of T-CONs each. Each of the plurality of T-CONs may then be controlled by the corresponding display module  10  to display all or part of the content at a frame rate of the content based on the signal received from the one or more processor  130 . The specific numbers in the above-described embodiment are provided as an example, and embodiments are not limited thereto. 
     Referring to  FIG.  4   , for convenience of description, the display module  10  is described as being driven at a frame rate of up to 120 Hz, but this is only an example and embodiments are not limited thereto. For example, the maximum frame rate of the display module  10  may vary from 144 Hz to 240 Hz, and the like. 
       FIG.  5    is a diagram illustrating content displayed on one region according to an embodiment. 
     Referring to  FIG.  5   , the first source device  200 - 1  may provide the first content 1, the third source device  200 - 3  may provide the second content 2, and the fourth source device  200 - 4  may provide the third content 3. 
     Here, each of the first to third contents 1, 2, and 3 may have a different frame rate. For example, the frame rate of the first content 1 may be a variable frame rate (VRR), the frame rate of the second content 2 may be 24 Hz, and the frame rate of the third content 3 may be 60 Hz. 
     In this case, the one or more processor  130  may control the display modules included in the first region in which the first content 1 is displayed (e.g., the first display module  10 - 1 , the second display module  10 - 2 , the third display module  10 - 3 , the fifth display module  10 - 5 , the sixth display module  10 - 6 , and the seventh display module  10 - 7 ) to operate the corresponding display modules at a variable frame rate. 
     Additionally, the one or more processor  130  may control the T-CON corresponding to the at least one display module (e.g., the fourth display module  10 - 4 ) included in the second region in which the second content 2 is displayed to operate the corresponding display module at 24 Hz. 
     Additionally, the one or more processor  130  may control the T-CON corresponding to the at least one display module (e.g., the eighth display module  10 - 8 ) included in the third region in which the third content 3 is displayed to operate the corresponding display module at 60 Hz. 
     As shown in  FIG.  5   , the unit capable of changing the frame rate may be a display module unit controlled by one T-CON. The minimum size of one region capable of displaying the content may correspond to the size of the display module  10  controlled by one T-CON. 
     The one or more processor  130  may control the T-CON corresponding to the at least one display module  10  included in the region in which the content is displayed to maintain the frame rate of the content at the time of outputting the content. 
     For example, the one or more processor  130  may change and output the frame rate of the display module  10  according to the type of the content. 
     For example, the one or more processor  130  may identify the type of the first content 1 displayed in the first region among the different regions on the display  120 . 
     The one or more processor  130  may obtain a frame rate corresponding to the identified type. For example, the one or more processor  130  may identify whether the first content 1 corresponds to movie content, game content, streaming content, or image content. 
     The one or more processor  130  may generate an interpolation frame or the like so that image processing to increase the frame rate of content. However, such image processing may cause delay. In the case of a first-person shooter game content for which it is important to minimize delay, the one or more processor  130  may control the T-CON of the display module (e.g., the first display module  10 - 1 , the second display module  10 - 2 , the third display module  10 - 3 , the fifth display module  10 - 5 , the sixth display module  10 - 6 , and the seventh display module  10 - 7 ) included in the first region so that the frame rate of the first content 1 is maintained (i.e., not perform the image processing to generate the interpolation frame or the like), to minimize delay when outputting the first content 1. 
     As another example, when the second content 2 is identified as the movie content, the one or more processor  130  may perform image processing to increase the frame rate of the content by generating the interpolation frame, or the like, and may control the T-CON of the display module (e.g., the fourth display module  10 - 4 ) included in the second region so that the second content 2 is displayed at a predetermined frame rate. For example, the one or more processor  130  may display the second content 2 having a frame rate of 24 Hz using a display module operating at 120 Hz. Here, a specific number is for convenience of description and is not limited thereto. 
     As another example, the one or more processor  130  may display content displayed in a particular region of the different regions at a predetermined frame rate. 
     For example, the one or more processor  130  may control the T-CON to operate at least one display module included in the second region of the different regions at a preset frame rate, and display the second content 2 in the second region. For example, when different regions on the display  120  are classified into a center region, a left top, a left bottom, a right top, and a right side, the center region may be displayed with the main interest content (hereinafter, main content) of the user, and content which is not the main content of the user but including additional information and the like (hereinafter referred to as sub-content) may be displayed. 
     According to an embodiment, the one or more processor  130  may identify the frame rate of the content displayed in the center region, and may control the T-CON included in the display module corresponding to the center region such that the display module (e.g., second display module  10 - 2 , the third display module  10 - 3 , the sixth display module  10 - 6 , and the second display module  10 - 7  of  FIG.  5   ) to operate at the identified frame rate. 
     The one or more processor  130  may control the T-CON so that the display module corresponding to the upper left region (e.g., the first display module  10 - 1  in  FIG.  5   ), the display module corresponding to the lower left region (e.g., the fifth display module  10 - 5  in  FIG.  5   ), the display module corresponding to the upper right end region (e.g., the fourth display module  10 - 4  in  FIG.  5   ) and the display module corresponding to the right bottom region (e.g., the 8th display module  10 - 8  in  FIG.  5   ) may operate at a predetermined frame rate to display the sub-content at a predetermined frame rate. 
     The above-described embodiments are provided as examples, and embodiments are not limited thereto. For example, the one or more processor  130  may display the main content at a predetermined frame rate, and may display the sub-content by maintaining the frame rate of the sub-content. 
     As another example, the one or more processor  130  may identify a region having a magnitude greater than or equal to a threshold value of the different regions. 
     The display module included in the identified region may control the T-CON to operate at a preset frame rate. For example, a region having a largest magnitude or a magnitude greater than a threshold value on the display  120  may be displayed with the user&#39;s main interest content (i.e., main content). 
     The one or more processor  130  may maintain and display the frame rate of the main content. As another example, the one or more processor  130  may control the T-CON of the display module included in the region in which the main content is displayed so that the main content is displayed at a predetermined frame rate.
