FIG. 1 is a block diagram illustrating a configuration of a display apparatus 100 according to one or more embodiments of the disclosure.

The display apparatus 100 may automatically change a screen setting. For example, the display apparatus 100 may be implemented as a modular display, and change the screen setting based on another display apparatus connected with the display apparatus 100. However, the disclosure is not limited thereto, and the display apparatus 100 can be any apparatus that includes a display, and can be connected with another display apparatus, and can change the screen setting. For example, the display apparatus 100 may be an apparatus that includes a display, and is connected with another display apparatus, and changes the screen setting based on the another display apparatus such as a TV, a desktop PC, a laptop, a smartphone, a tablet PC, etc.

According to FIG. 1, the display apparatus 100 includes a memory 110, a display 120, and a processor 130.

The memory 110 may refer to hardware that stores information such as data, etc. in an electric or a magnetic form so that the processor 130, etc. can access the information. For this, the memory 110 may be implemented as at least one hardware among a non-volatile memory, a volatile memory, a flash memory, a hard disk drive (HDD) or a solid state drive (SSD), a RAM, a ROM, etc.

In the memory 110, at least one instruction necessary for the operations of the display apparatus 100 or the processor 130 may be stored. Here, the instruction is a code unit instructing the operation of the display apparatus 100 or the processor 130, and it may have been drafted in a machine language which is a language that can be understood by a computer. Alternatively, in the memory 110, a plurality of instructions that perform specific tasks of the display apparatus 100 or the processor 130 may be stored as an instruction set.

Also, in the memory 110, data which is information in bit or byte units that can indicate characters, numbers, images, etc. may be stored. For example, in the memory 110, a screen setting module, etc. may be stored.

The memory 110 may be accessed by the processor 130, and reading/recording/correction/deletion/update, etc. for an instruction, an instruction set, or data may be performed by the processor 130.

The display 120 is a component that displays images, and may be implemented as displays in various forms such as a liquid crystal display (LCD), an organic light emitting diodes (OLED) display, a plasma display panel (PDP), etc. Inside the display 120, a driving circuit that may be implemented in forms such as an a-si TFT, a low temperature poly silicon (LTPS) TFT, an organic TFT (OTFT), etc., and a backlight unit, etc. may also be included together. The display 120 may be implemented as a touch screen combined with a touch sensor, a flexible display, a 3D display, etc.

The processor controls the overall operations of the display apparatus 100. Specifically, the processor 130 may be connected with each component of the display apparatus 100 and control the overall operations of the display apparatus 100. For example, the processor 130 may be connected with components such as the memory 110, the display 120, a communication interface, etc., and control the operations of the display apparatus 100.

The at least one processor 130 may include one or more of a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a many integrated core (MIC), a neural processing unit (NPU), a hardware accelerator, or a machine learning accelerator. The at least one processor 130 may control one or a random combination of other components of the display apparatus 100, and perform operations regarding communication or data processing. The at least one processor 130 may execute one or more programs or instructions stored in the memory 110. For example, the at least one processor 130 may perform the method according to one or more embodiments of the disclosure by executing the one or more instructions stored in the memory 110.

In case the method according to one or more embodiments of the disclosure includes a plurality of operations, the plurality of operations may be performed by one processor, or performed by a plurality of processors. For example, when a first operation, a second operation, and a third operation are performed by the method according to one or more embodiments, all of the first operation, the second operation, and the third operation may be performed by a first processor, or the first operation and the second operation may be performed by the first processor (e.g., a generic-purpose processor), and the third operation may be performed by a second processor (e.g., an artificial intelligence-dedicated processor).

The at least one processor 130 may be implemented as a single core processor including one core, or it may be implemented as one or more multicore processors including a plurality of cores (e.g., multicores of the same kind or multicores of different kinds). In case the at least one processor 130 is implemented as multicore processors, each of the plurality of cores included in the multicore processors may include an internal memory of the processor such as a cache memory, an on-chip memory, etc., and a common cache shared by the plurality of cores may be included in the multicore processors. Also, each of the plurality of cores (or some of the plurality of cores) included in the multicore processors may independently read a program instruction for implementing the method according to one or more embodiments of the disclosure and perform the instruction, or the plurality of entire cores (or some of the cores) may be linked with one another, and read a program instruction for implementing the method according to one or more embodiments of the disclosure and perform the instruction.

In case the method according to one or more embodiments of the disclosure includes a plurality of operations, the plurality of operations may be performed by one core among the plurality of cores included in the multicore processors, or they may be implemented by the plurality of cores. For example, when the first operation, the second operation, and the third operation are performed by the method according to one or more embodiments, all of the first operation, the second operation, and the third operation may be performed by a first core included in the multicore processors, or the first operation and the second operation may be performed by the first core included in the multicore processors, and the third operation may be performed by a second core included in the multicore processors.

In the embodiments of the disclosure, the at least one processor 130 may mean a system on chip (SoC) wherein at least one processor and other electronic components are integrated, a single core processor, a multicore processor, or a core included in the single core processor or the multicore processor. Also, here, the core may be implemented as a CPU, a GPU, an APU, a MIC, an NPU, a hardware accelerator, or a machine learning accelerator, etc., but the embodiments of the disclosure are not limited thereto. However, from below, the operations of the display apparatus 100 will be explained with the expression ‘the processor 130,’ for the convenience of explanation.

If it is identified that the display apparatus 100 is connected with another display apparatus, the processor 130 may identify a past connection history with the another display apparatus stored in the memory 110, and change the screen setting of the display 120 based on screen setting information corresponding to the past connection history.

For example, the memory 110 may store a plurality of identification information of a plurality of electronic apparatuses and a plurality of screen setting information corresponding to each of the plurality of identification information as the past connection history. For example, in case the display apparatus 100 is connected to a first electronic apparatus, the processor 130 may map first identification information of the first electronic apparatus and first screen setting information of the display 120, and store the information in the memory 110. Also, in case the display apparatus 100 is connected to a second electronic apparatus after the connection with the first electronic apparatus was released, the processor 130 may map second identification information of the second electronic apparatus and second screen setting information of the display 120, and store the information in the memory 110.

If it is identified that the display apparatus 100 is connected with another display apparatus, the processor 130 may identify screen setting information corresponding to the another display apparatus among the plurality of screen setting information stored in the memory 110, and change the screen setting of the display 120 based on the identified screen setting information.

In the aforementioned embodiment, in case the display apparatus 100 is connected to the first electronic apparatus again after the connection with the second electronic apparatus was released, the processor 130 may identify the first electronic apparatus, and change the screen setting of the display 120 based on the first screen setting information mapped to the identification information of the first electronic apparatus. That is, the processor 130 may automatically change the screen setting of the display 120, and the user may use the display apparatus 100 with the previous screen setting without having to change the screen setting separately.

After the display apparatus 100 is connected with the first electronic apparatus, the processor 130 may change the screen setting of the display 120, and if the screen setting of the display 120 is re-changed according to the user's manipulation, the processor 130 may map the first identification information of the first electronic apparatus and the re-changed screen setting information of the display 120, and store the information in the memory 110. Here, the processor 130 may delete the past screen setting information that was mapped to the first identification information of the first electronic apparatus. Alternatively, if the screen setting of the display 120 is re-changed, the processor 130 may update the past screen setting information that was mapped to the first identification information to the current screen setting information.

The display apparatus 100 may further include a communication interface, and if another screen setting information of another display included in another display apparatus is received from the another display apparatus through the communication interface, the processor 130 may compare the screen setting information and the another screen setting information, and if it is identified that the screen setting information and the another screen setting information are different as a result of the comparison, the processor 130 may control the display 120 to display a message inducing to select one of the screen setting information or the another screen setting information.

For example, in case the display apparatus 100 was connected to another display apparatus in the past, the screen of the display 120 of the display apparatus 100 and the screen of another display of the another display apparatus may be in a state of having been set based on the screen setting information. Afterwards, when the connection of the display apparatus 100 with the another display apparatus is released, and the screen setting of the another display apparatus is changed, even if the display apparatus 100 is re-connected to the another display apparatus, the screen settings of the two apparatuses may be different. In this case, the processor 130 may control the display 120 to display a message inducing to select one of the two kinds of screen setting information.

The display apparatus 100 may further include a user interface, and if a user instruction selecting one of screen setting information or another screen setting information is received through the user interface, the processor 130 may change the screen setting of the display 120 based on the screen setting information corresponding to the user instruction.

If a user instruction selecting screen setting information is received through the user interface, the processor 130 may change the screen setting of the display 120 based on the screen setting information, and control the communication interface to transmit the screen setting information to another display apparatus. Alternatively, if a user instruction selecting another screen setting information is received through the user interface, the processor 130 may change the screen setting of the display 120 based on the another screen setting information, and map the identification information of the another display apparatus and the another screen setting information, and store the memory in the memory 110.

In the above, one or more embodiments wherein the display apparatus 100 performs an operation of synchronizing the screen setting with another display apparatus was explained. However, the disclosure is not limited thereto, and another display apparatus which is not the display apparatus 100 may perform an operation of synchronizing the screen setting.

For example the display apparatus 100 may further include a communication interface, and the processor 130 may control the communication interface to transmit screen setting information to another display apparatus. In this case, the another display apparatus may compare the screen setting information received from the display apparatus 100 and the another screen setting information of the another display apparatus, and if it is identified that the screen setting information and the another screen setting information are different as a result of the comparison, control the another display to display a message inducing to select one of the screen setting information or the another screen setting information.

If a user instruction selecting the screen setting information is received, the another display apparatus may change the screen setting of the another display based on the screen setting information. In this case, the another display apparatus does not provide information related to the screen setting to the display apparatus 100, and thus the display apparatus 100 may not perform any additional operation. Alternatively, if a user instruction selecting the another screen setting information is received, the another display apparatus may transmit the another screen setting information to the display apparatus 100. In this case, the processor 130 may change the screen setting of the display 120 based on the another screen setting information, and map the identification information of the another display apparatus and the another screen setting information, and store the information in the memory 110.

In the above, it was explained that the processor 130 changes the screen of the display 120 based on a past connection history with another display apparatus, but the disclosure is not limited thereto. For example, the processor 130 may change the screen of the display 120 by further considering a communication standard with another display apparatus as well as the another display apparatus. For example, in case the display apparatus 100 is connected with another display apparatus in an HDMI standard, the processor 130 may change the screen setting of the display 120 based on the first screen setting information, and in case the display apparatus 100 is connected with another display apparatus in a Bluetooth standard, the processor 130 may change the screen setting of the display 120 based on the second screen setting information.

The display apparatus 100 may further include a power interface and a communication interface, and if the display apparatus 100 is connected with another display apparatus, the processor 130 may receive power from the another display apparatus through the power interface, and receive a content from the another display apparatus through the communication interface.

The processor 130 may change the screen of the display 120 by further considering the type of a content as well as another display apparatus. For example, if a content is received from another display apparatus, the processor 130 may identify the type of the content, and if the type of the content is a first type, the processor 130 may change the screen setting of the display 120 based on the first screen setting information, and if the type of the content is a second type, the processor 130 may change the screen setting of the display 120 based on the second screen setting information.

If connection with another display apparatus is released, the processor 130 may map the identification information of the another display apparatus and the screen setting information of the display 120 on a time point when the connection with the another display apparatus is released, and store the information in the memory 110.

The display apparatus 100 may further include a sensor, and the processor 130 may identify that the display apparatus 100 is connected with another display apparatus through the sensor. For example, the processor 130 may identify another display apparatus through a near field communication (NFC) function. However, the disclosure is not limited thereto, and any method that can identify another display apparatus can be used. For example, the display apparatus 100 may be connected with another display apparatus 200 through a pogo-pin connector or a USB-C type connector, and the processor 130 may identify whether the display apparatus 100 is connected with another display apparatus, identification information, etc. based on data received through the pogo-pin connector or the USB-C type connector.

Alternatively, the communication interface 140 may include a wired communication interface such as an HDMI, a DP, a Thunderbolt, a USB, an RGB, a D-SUB, a DVI, etc.

Other than the above, the communication interface 140 may include at least one of a local area network (LAN) module, an Ethernet module, or a wired communication module that performs communication by using a pair cable, a coaxial cable, or an optical fiber cable, etc.

The user interface 150 may be implemented as a button, a touch pad, a mouse, and a keyboard, etc., or implemented as a touch screen that can perform both of a display function and a manipulation input function. Here, a button may be various types of buttons such as a mechanical button, a touch pad, a wheel, etc. formed in any areas such as the front surface part, the side surface part, the rear surface part, etc. of the exterior of the main body of the display apparatus 100.

The power interface 160 may be an interface for receiving power. However, the disclosure is not limited thereto, and the power interface 160 may be implemented in a form of being combined with the communication interface 140. For example in case the communication interface 140 is implemented in the HDMI standard, the communication interface 140 may include the power interface 160.

The sensor 170 may be a component for identifying another display apparatus. For example, the sensor 170 may include an NFC function, and the processor 130 may identify another display apparatus based on information received through the sensor. However, the disclosure is not limited thereto, and the sensor 170 can be any form if it is a component for identifying another display apparatus. Also, the processor 130 may receive identification information of another display apparatus directly from the another display apparatus through the communication interface 140.

The microphone 180 is a component for receiving input of a sound and converting the sound into an audio signal. The microphone 180 may be electrically connected with the processor 130, and may receive a sound by control by the processor 130.

For example, the microphone 180 may be formed as an integrated type integrated to the upper side or the front surface direction, the side surface direction, etc. of the display apparatus 100. Alternatively, the microphone 180 may be provided on a remote control, etc. separate from the display apparatus 100. In this case, the remote control may receive a sound through the microphone 180, and provide the received sound to the display apparatus 100.

The microphone 180 may include various components such as a microphone collecting a sound in an analog form, an amp circuit that amplifies the collected sound, an A/D conversion circuit that samples the amplified sound and converts the sound into a digital signal, a filter circuit that removes noise components from the converted digital signal, etc.

The microphone 180 may be implemented in the form of a sound sensor, and it can be in any type if it is a component that can collect sounds.

The speaker 190 is a component that outputs not only various kinds of audio data processed at the processor 130, but also various kinds of notification sounds or voice messages, etc.

The camera 195 is a component for photographing a still image or a moving image. The camera 195 may photograph a still image on a specific time point, but may also photograph a still image consecutively.

The camera 195 may photograph the front side of the display apparatus 100, and may thereby photograph the actual environment in front of the display apparatus 100. The processor 130 may also identify another display apparatus through the camera 195.

The camera 195 includes a lens, a shutter, an aperture, a solid state imaging element, an analog front end (AFE), and a timing generator (TG). The shutter adjusts the time when a light reflected on a subject enters the camera 195, and the aperture adjusts a light amount introduced into the lens by mechanically increasing or decreasing the size of an opening through which a light enters. When a light reflected on a subject is accumulated as photo charges, the solid state imaging element outputs a phase by the photo charges as an electric signal. The TG outputs a timing signal for reading out pixel data of the solid state imaging element, and the AFE samples the electric signal output from the solid state imaging element and digitalizes the signal.

As described above, the display apparatus can improve the user convenience by automatically changing the screen setting of the display 120.

Also, the display apparatus 100 can remove a sense of difference due to differences of screens as the user uses a plurality of displays by synchronizing the screen setting with another display apparatus connected with the display apparatus 100.

Hereinafter, operations of the display apparatus 100 will be described in more detail through FIG. 3 to FIG. 8.
