Description

Display device for indicating pointer movement between screens and display method thereof

[0001] The present disclosure relates to a display device and a display method thereof, and more particularly, to a display device and a display method thereof for displaying a movement state of a pointer between screens within a plurality of display devices or within one display device.

[0002] Advances in electronic technology have led to the development of electronic devices offering a variety of functions. In particular, various types of display devices have recently been developed, enhancing user convenience.

[0003] For example, a user may be able to split the entire screen of a single display device into multiple areas to display multiple pieces of information simultaneously on a single screen, or may be able to use multiple display devices with a single input device.

[0004] In this case, each display device can display a pointer corresponding to a single input device. For example, if a mouse is connected, the user can move the mouse to move the pointer to a different area on the screen or to another nearby display device.

[0005] However, depending on the characteristics of the display device or the content displayed on the display device, some display devices or content do not support the pointer display function. In these cases, users may not be able to accurately recognize the pointer's location when moving it.

[0006] According to the present disclosure, a display device according to at least one embodiment includes a display, a communication unit for communicating with an external display device to which an input device is connected, and a processor, wherein the processor receives information about the pointer from the external display device through the communication unit when the pointer corresponding to the input device is displayed on a screen on the external display device and the pointer leaves the screen due to movement of the input device.

[0007] The processor controls the display to display the pointer based on the information received through the communication unit when the display device is in a state capable of displaying a pointer, and controls the display to display a graphic object indicating a display restriction state when the display device is in a state in which pointer display is restricted.

[0008] A display device according to one or more embodiments of the present disclosure includes a display, a communication unit, and a processor, wherein the processor controls the display to divide the entire screen of the display into a plurality of split screens when a user operation for splitting the screen is input, and to display a movable pointer within one of the split screens according to an operation of an input device.

[0009] The processor controls the display to display a graphic object indicating a pointer display restriction state when the pointer moves to a split screen where the pointer display is restricted.

[0010] A display method of a display device according to at least one embodiment of the present disclosure includes the steps of: receiving information about a pointer from an external display device when the pointer corresponding to the input device is displayed on a screen on an external display device connected to the input device and the pointer moves off the screen due to movement of the input device; and displaying a graphic object indicating a pointer display restriction state when the display device is in a state where pointer display is restricted.

[0019] Hereinafter, the present disclosure will be described in detail with reference to the attached drawings.

[0020] The terms used in the embodiments of this disclosure have been selected from widely used, current terms, taking into account the functions of this disclosure. However, these terms may vary depending on the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Furthermore, in certain cases, terms may be arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the description of the relevant disclosure. Therefore, the terms used in this disclosure should not be defined simply as names of terms, but rather based on the meanings of the terms and the overall content of this disclosure.

[0021] In this specification, expressions such as “has,” “can have,” “includes,” or “may include” indicate the presence of a feature (e.g., a number, function, operation, or component such as a part), and do not exclude the presence of additional features.

[0023] As used herein, the expressions “first,” “second,” “first,” or “second,” etc., may describe various components, regardless of order and / or importance, and are only used to distinguish one component from another, but do not limit the components.

[0024] When it is said that a component (e.g., a first component) is “(operatively or communicatively) coupled with / to” or “connected to” another component (e.g., a second component), it should be understood that the component may be directly coupled to the other component, or may be connected through another component (e.g., a third component).

In this application, terms such as "comprise" or "consist of" are intended to indicate the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but should be understood not to preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0026] In the present disclosure, a "module" or "part" performs at least one function or operation and may be implemented as hardware or software, or as a combination of hardware and software. Furthermore, multiple "modules" or multiple "parts" may be integrated into at least one module and implemented as at least one processor (not shown), excluding any "modules" or "parts" that need to be implemented as specific hardware.

[0027] In this specification, the term user may refer to a person using an electronic device or a device using an electronic device (e.g., an artificial intelligence electronic device).

[0028] An embodiment of the present disclosure will be described in more detail with reference to the attached drawings below.

[0029] FIG. 1 and FIG. 2 are drawings schematically illustrating the operation of a display device according to various embodiments of the present disclosure.

[0030] Figure 1 illustrates a case where multiple display devices are connected and used to one input device.

[0031] Here, the input device (10) is a configuration for receiving various user operations for controlling the operation of each display device (100, 200). Specifically, various devices such as a mouse, a keyboard, a touch pad, a touch screen, a shape input panel, a shape processing panel, a joystick, and a pointing stick can be the input device (10). At least one of each display device (100, 200) can display a pointer corresponding to the input device (10). A pointer refers to an object displayed on the screen so that a user can specify a point on the screen. The pointer can be implemented in various forms such as a cursor, a thumbnail image, an icon, a photo, and a shape. In the present disclosure, a cursor using a mouse is described as a reference.

[0032] In FIG. 1, the input device (10) is shown as being connected to the second display device (200), but this is not necessarily limited to the present invention, and the second display device (200) may be connected to a separate terminal device (e.g., a PC, a laptop, a tablet, etc.) to which the input device (10) is connected.

[0033] The second display device (200) displays the position of the pointer at a point on the screen and then moves and displays the pointer according to the movement of the input device (10). When the user moves the input device (10) further while the pointer has reached the edge of the second display device (200), the second display device (200) controls the first display device (100) so that the pointer can be moved and displayed toward an external device, i.e., the first display device (100).

[0034] FIG. 2 illustrates a case where an input device (10) is connected to a first display device (100) and the entire screen within the first display device (100) is divided into multiple areas (101, 102, 103) for use. In FIG. 2, only one display device (100) is illustrated, but when a second display device (200) is connected to the input device (10) and the first display device (100) as in FIG. 1, the screen of the second display device (200) may be divided into multiple areas for use as in FIG. 2.

[0035] According to FIG. 2, when the user continues to move the input device (10) to the right while the pointer is displayed in one area (e.g., the first area (101)), the first display device (100) sequentially moves and displays the pointer in the direction from the first area (101) to the second area (102) and the third area (103).

[0036] Specifically, when the display device (100) detects movement of the input device (10), it identifies the movement distance and direction. The display device (100) updates the pointer coordinate information on which the pointer is displayed based on the movement distance and direction.

[0037] Such pointer coordinate information may be generated by the display device (100) itself according to the present disclosure, but is not limited thereto. When a source device such as a PC body or a server is connected to the display device (100), pointer position information may be generated by the source device.

[0038] According to the example illustrated in FIG. 1, a pointer can be displayed on the first display device (100) or the second display device (200) depending on the operation of the input device (10).

[0039] The first display device (100) can communicate with the second display device (200) through various types of wired / wireless communication networks, broadcast communication networks, optical communication networks, cloud networks, etc. Alternatively, the first display device (100) can be connected to the second display device (200) through methods such as Wi-Fi, Bluetooth, NFC (Near Field Communication), etc. without a separate medium.

[0040] The first and second display devices (100, 200) may each be implemented as a TV, but are not limited thereto, and any device having a display and capable of receiving an input signal from an input device may be used. Specifically, the display device (100) is not limited to any device having a display function, such as a monitor for a desktop PC, a laptop, a smartphone, a tablet PC, a video wall, a large format display (LFD), a digital signage, a digital information display (DID), a projector, etc., and may be applied.

[0041] Each display device (100, 200) can display various contents according to the user's settings. For example, the user can set the second display device (200) to display a PC screen and the first display device (100) to display VOD (Video On Demand) contents received via the Internet. In addition, various contents such as TV broadcast screens, cable broadcast screens, application execution screens, playback screens of media players such as Blu-ray discs, and game screens of game consoles can be displayed on each display device (100, 200) according to the user's settings.

[0042] In addition, as shown in FIG. 2, when a single screen is divided into multiple screen areas (101, 102, 103), the user can set the content to be displayed in each area (101, 102, 103) in various ways as described above. Accordingly, multiple split screens can be displayed within a single display.

[0043] Some content may have restricted pointer display. Alternatively, the display device itself may not support pointer display. For example, certain over-the-top (OTT) channels may restrict pointer display because the pointer obscures the screen. Furthermore, console gaming systems may not support pointer display.

[0044] In FIG. 1, when the first display device (100) is in a state where pointer display is restricted, the first display device (100) displays a graphic object indicating that pointer display is restricted when a situation arises where the pointer must be moved from the second display device (200). The user can unconsciously move the pointer toward the first display device (100), check the aforementioned graphic object, and then control the input device (10) to move the pointer back toward the second display device (200) for display.

[0045] In addition, in FIG. 2, if the second area (102) is in a state where pointer display is restricted, the first display device (100) can display a graphic object indicating that the second area (102) is in a display restricted state when it is determined that the pointer display coordinates have moved into the second area (102).

[0046] A graphic object indicating a display restriction status can be expressed in various forms. For example, it can be a text message or graphic message informing that the pointer position cannot be displayed on the device or screen area, a virtual pointer that is expressed differently from a normal pointer, and various graphic effects or animation effects displayed on the edge so as not to obscure the screen. Here, a virtual pointer can be a pointer that is different from a normal pointer in at least one of color, size, shape, and transparency. A virtual pointer is a pointer that has at least some of the functions of a normal pointer restricted.

[0047] For example, assuming that an execution command is input when the user clicks the left mouse button while the pointer is displayed, the first display device (100) may not perform any action even if the left mouse button is clicked while the virtual pointer is displayed. In this case, the function assigned to the right mouse button for the virtual pointer may be supported in the same way as the normal pointer, but is not limited thereto, and the virtual pointer may be implemented so as to simply indicate the pointer position and not support any function. The virtual pointer may be called various other names such as a ghost pointer, a translucent pointer, a ghost cursor, a fake pointer, etc., but in the present disclosure, it is uniformly described as a virtual pointer.

[0048] As described above, graphic objects can be expressed in various forms to visually indicate a state in which the pointer display of the display device (100) is restricted, or to visually inform the user of the pointer's location by replacing the pointer. This will be described in detail again with reference to the drawings in the following section.

[0049] By displaying graphic objects, the user can easily determine the current location of the pointer.

[0050] FIG. 3 is a block diagram illustrating a configuration of a display device according to various embodiments of the present disclosure. According to FIG. 3, a display device (100) includes a display (110), a communication unit (120), and a processor (130). The display device (100) of FIG. 3 corresponds to the first display device (100) of FIGS. 1 and 2.

[0051] The display (110) may be implemented as a display including a self-luminous element or a display including a non-luminous element and a backlight. For example, it may be implemented as various types of displays such as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diodes) display, an LED (Light Emitting Diodes), a micro LED, a Mini LED, a PDP (Plasma Display Panel), a QD (Quantum dot) display, a QLED (Quantum dot light-emitting diodes), etc. The display (110) may also include a driving circuit, a backlight unit, etc., which may be implemented in a form such as an a-si TFT, an LTPS (low temperature poly silicon) TFT, an OTFT (organic TFT), etc.

[0052] The communication unit (120) can perform communication by being connected to various external devices via wires or wirelessly.

[0053] For example, the communication unit (120) may be connected to the input device (10) or the external display device (200) to which the input device (10) is connected, either wired or wirelessly, to receive a control signal of the input device (10) or receive information on the display coordinates of a pointer generated in the external display device (200).

[0054] When the input device (10) is directly connected to the display device (100), the communication unit (120) can transmit a control signal of the input device (10) to the external display device (200), or transmit information on the display coordinates of the pointer generated in the display device (100) to the external display device (200).

[0055] The communication unit (120) can transmit and receive various signals and data to and from external devices through communication methods such as Bluetooth, AP-based Wi-Fi (Wireless LAN network), Zigbee, wired / wireless LAN (Local Area Network), WAN (Wide Area Network), Ethernet, IEEE 1394, HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), MHL (Mobile High-Definition Link), AES / EBU (Audio Engineering Society / European Broadcasting Union), optical, and coaxial.

[0056] The processor (130) is connected to each component of the display device (100) and is configured to control the overall operation of the display device (100). The processor (130) may be implemented as a digital signal processor (DSP), a microprocessor, a GPU (Graphics Processing Unit), an AI (Artificial Intelligence) processor, an NPU (Neural Processing Unit), or a TCON (Time Controller) for processing a digital image signal. However, the present invention is not limited thereto, and may include one or more of a central processing unit (CPU), a MCU (Micro Controller Unit), an MPU (micro processing unit), a controller, an application processor (AP), a communication processor (CP), or an ARM processor, or may be defined by the relevant terminology. In addition, the processor (130) may be implemented as a SoC (System on Chip), an LSI (Large Scale Integration) having a built-in processing algorithm, or may be implemented in the form of an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array).

[0057] In addition, the processor (130) for executing the artificial intelligence model according to one embodiment may be implemented through a combination of a general-purpose processor such as a CPU, an AP, a DSP (Digital Signal Processor), a graphics-only processor such as a GPU, a VPU (Vision Processing Unit), or an artificial intelligence-only processor such as an NPU, and software. The processor (130) may be controlled to process input data according to predefined operation rules or an artificial intelligence model stored in a memory. Alternatively, if the processor (130) is a dedicated processor (or an artificial intelligence-only processor), it may be designed as a hardware structure specialized for processing a specific artificial intelligence model. For example, the hardware specialized for processing a specific artificial intelligence model may be designed as a hardware chip such as an ASIC or an FPGA.

[0058] When the processor (130) is implemented as a dedicated processor, it may be implemented to include a memory for implementing the embodiments of the present disclosure, or it may be implemented to include a memory processing function for utilizing external memory. The processor (130) may be implemented as one or more processors.

[0059] When an input device (10) is connected to an external display device (200) and an event occurs in which a user moves the input device (10) to move the pointer of the input device (10) from the screen of the external display device (200) to the screen of the display device (100), the external display device (200) can transmit information about the pointer. The information may include, but is not limited to, information about display coordinates, and various display options such as the size, shape, color, and transparency of the pointer, as well as information about functions matched to the pointer, can be added.

[0060] The processor (130) receives information about the pointer through the communication unit (120). In this case, information about the display coordinates of the pointer may be generated from an external display device (200) or an input device (10).

[0061] The processor (130) determines whether the display device (100) is in a state where pointer display is restricted. Whether display is restricted may be determined based on the characteristics of the content source displayed on the display device (100), the characteristics of the content channel, and the characteristics of the content itself. For example, if an external input source that does not support a mouse, such as a console device or a set-top box, is connected to the display device (100), the processor (130) may determine that pointer display is restricted. Alternatively, if an application or broadcast channel that does not support a mouse is set as a content source, or if various game screens are displayed, the processor (130) may determine that pointer display is restricted. Information on external input sources, content sources, game content, etc. for which pointer display is restricted may be stored in advance in the display device (100), or may be recognized by the processor (130) based on metadata or other related information of each content.

[0062] If the display device (100) is capable of displaying a pointer, the processor (130) can control the display (110) to display a pointer at a point on the display screen (110) based on the coordinate values ​​included in the pointer display coordinate information.

[0063] When the pointer display of the display device (100) is in a restricted state, the processor (130) controls the display (110) to display a graphic object indicating the restricted display state.

[0064] As described above, graphic objects can be implemented in various forms, such as text messages, graphic messages, virtual pointers, highlight indicators, blinking border indicators, border animation effects, cursor animation effects, translucent icons (e.g., translucent arrows), and combinations thereof.

[0065] When a graphic object is displayed in a movable form, such as a virtual pointer or a semi-transparent icon, the processor (130) can move the position of the graphic object based on the received pointer display coordinate information continuously received from the external display device (200) according to the movement of the input device (10). Accordingly, even if the user cannot utilize all the functions of the input device (10) as they are, the user can easily determine the current position of the pointer.

[0066] In the above, the case where the display device (100) of FIG. 3 is the first display device (100) that is not directly connected to the input device (10) has been described, but the second display device (200) may also be implemented with the same configuration as FIG. 3. In this case, when the processor of the second display device (200) detects the movement of the input device (10), it moves the pointer display on the display according to the movement. If it is detected that the input device (10) continues to move even when the pointer has reached the edge of the display, the processor of the second display device (200) may generate various pieces of information including the display coordinates of the pointer and then transmit the information to an external display device, i.e., the first display device (100), through the communication unit. The display coordinates of the pointer may be determined within a range exceeding the coordinate values ​​included in the entire screen of the display. That is, the processor (130) may generate the display coordinates of the pointer based on a single screen that includes all screens of the entire display devices.

[0067] For example, if the coordinate value of a point on the rightmost edge of the display of the second display device (200) is (x, y), the coordinate value of a point on the leftmost edge of the same line of the first display device (100) can be expressed as (x+1, y). However, this is only an example, and the coordinate value can be expressed in the same way, but a device ID or other identification information can be added. As described above, information on the display coordinates of the pointer can be implemented in various forms. Upon receiving such information, the first display device (100) can determine whether or not it is a situation in which a pointer should be displayed on its display (110).

[0068] When multiple display devices are connected to each other, the positions of other display devices based on the display device to which the input device (10) is connected can be determined according to the user's settings. The processor (130) can set the range of the pointer's display coordinate values ​​according to the user's settings. For example, in the example of FIG. 1, the first display device (100) is located on the right side of the second display device (200), but if the user has set it to the left, when the user moves the input device (10) all the way to the left, the pointer will move from the second display device (200) to the first display device (100). However, this is not limited to this, and if the second display device (200) or the first display device (100) is equipped with a camera or proximity sensor that can recognize the positions of each other, the settings may be changed according to the positions.

[0069] In FIG. 3, the display device (100) is illustrated and described based on the case where it includes basic configurations for displaying a screen area where the use of a pointer is not possible on the display (110), but depending on the embodiment, the display device (100) may further include additional configurations.

[0070] Figure 4 is a block diagram showing a detailed configuration of a display device according to various embodiments.

[0071] According to FIG. 4, the display device (100) may include a display (110), a communication unit (120), a processor (130), a memory (140), a sensor unit (150), and a light source unit (160). Among the configurations illustrated in FIG. 4, a detailed description of configurations that overlap with those illustrated in FIG. 3 will be omitted.

[0072] The memory (140) can store at least one command required for the operation of the display device (100) or the processor (130). The memory (140) can store various data such as information on the display coordinates of the pointer, information on the pointer coordinate value range of the entire screen of the display (110), setting information for setting whether the pointer display is limited, and information for expressing a graphic object. For example, the memory (140) can store information on the pointer received from the external display device (200) through the communication unit (120). The memory (140) can also store coordinate information of the pointer that changes according to the movement direction and distance of the input device (10).

[0073] The memory (140) may be implemented in the form of memory embedded in the display device (100) or in the form of memory detachable from the display device (100) depending on the purpose of data storage. For example, data for driving the display device (100) may be stored in a memory embedded in the display device (100), and data for the expansion function of the display device (100) may be stored in a memory detachable from the display device (100).

[0074] Meanwhile, the memory embedded in the display device (100) may be implemented as at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)), non-volatile memory (e.g., one time programmable ROM (OTPROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard drive, or solid state drive (SSD)).

[0075] The memory (140) may be implemented as a single memory that stores data generated from various operations according to the present disclosure. However, according to another embodiment, the memory (140) may be implemented to include multiple memories that each store different types of data or each store data generated at different stages.

[0076] The sensor unit (150) may be configured to identify the position or direction of the external display device (200). For example, if the input device (10) moves to an extent that the pointer leaves the entire screen area of ​​the display (110), the processor (130) identifies the position or direction of the external display device (200) based on the sensing value acquired through the sensor unit (150). The processor (130) may determine whether to transmit information about the pointer to the external display device (200) based on the identified position or direction information and the movement direction of the pointer. That is, if it is identified that the user is moving the pointer in the right direction, the processor (130) may move the pointer to the external display device (200) located in the right direction with respect to the display device (100).

[0077] The sensor unit (150) may include various sensors depending on the type of display device (100). For example, if the display device (100) is a mobile device, it may include at least one of a proximity sensor, a distance sensor, a gyro sensor, an acceleration sensor, a geomagnetic sensor, and a location information sensor (GPS). The sensor unit (150) may have any form as long as it is configured to identify the position or direction of the external display device (200).

[0078] The light source unit (160) is configured to display lighting effects to the user. The light source unit (150) may include at least one light source selected from the group consisting of a lamp, an LED, and a laser. The light source unit (150) may be placed in various external parts of the display device (100), such as the bezel area, the rear of the housing, or the side.

[0079] The processor (130) can provide the user with pointer-related information by using a dimming function to adjust the intensity of the light source or by changing the color of the light source. When the display device (100) has a pointer display function and the pointer moves within the display screen of the display device (100), the processor (130) controls the light source unit (160) to provide a lighting effect, such as displaying a backlight on the back of the display device (100). By visually checking the device that is blinking or brightly displayed, the user can intuitively know which device the pointer is currently located on.

[0080] Alternatively, the processor (130) may be implemented to control the light source (160) when the pointer is moved while the pointer display function is limited. Alternatively, the color (e.g., green) when the pointer display function is enabled may be implemented to be expressed differently from the color (e.g., red) when the pointer display function is limited.

[0081] FIGS. 5 to 9 are diagrams for explaining a state in which pointer display is restricted when a pointer is moved between display devices according to various embodiments of the present disclosure. Specifically, FIGS. 5 to 9 illustrate a case in which a pointer is moved from an external display device (200) to a display device (100) in which pointer display is restricted.

[0082] In FIG. 5, the second display device (200) is implemented as a mobile phone to which an input device (10) is connected, and the first display device (100) is implemented as a TV to which an external source device (50) is connected. If the external source device (50) is a console game machine or a set-top box, it does not support a pointer display function. Therefore, the processor (130) of the first display device (100) can recognize that the display device (100) is in a state in which pointer display is restricted, based on the type of the external source device (50). When the user moves the input device (10), the pointer (501) moves within the screen of the second display device (200). In this state, when the user inputs a user operation to move the pointer (501) to the first display device (100) (i.e., an operation to move the input device (10), the second display device (200) can control the display (110) to display a graphic object to guide the user of the pointer display restriction state. Figure 5 illustrates a case where a graphic object is implemented in the form of a guide window (510) containing text.

[0083] The guidance window (510) may include a message indicating that the display device (100) is currently connected to an external source device (50) that cannot display a pointer, i.e., a content source. Additionally, various other information may be displayed, such as information indicating content sources that can use a pointer, and information indicating how to control the display device (10) or other devices without a pointer.

[0084] For example, according to FIG. 5, the processor (130) can control the display (110) to display a message guiding a state in which keyboard use is possible, a message guiding keyboard usage, and user menu information controllable using a mouse cursor on the screen of the display (110) in a state in which pointer display is restricted.

[0085] In this case, the processor (130) can control the display (110) to enable the use of a pointer (501) in the guidance window (510) so that the user can use the user menu displayed in the guidance window (510).

[0086] Figure 6 illustrates a case where a graphic object is implemented as a virtual pointer.

[0087] As illustrated in FIG. 6, the processor (130) displays a virtual pointer (610), which is a graphic object that replaces the pointer (601), when the pointer (601) displayed on the external display device (200) moves to the display device (100) and the display device (100) is in a state where pointer display is restricted.

[0088] Referring to FIG. 6, a virtual pointer (610) is a graphic object that is displayed translucently on the display (110) and can be moved according to the operation of the input device (10). The virtual pointer (610) may have some or all of its functions limited.

[0089] In FIG. 6, it is illustrated that the processor (130) controls the display (110) to display a semi-transparent arrow (620) for indicating the direction of pointer movement in addition to the virtual pointer (610), but this may be omitted depending on the embodiment, or only the semi-transparent arrow (620) may be displayed.

[0090] If the pointer is not displayed on the display (110) screen, the user cannot recognize the current position of the pointer. In particular, when three or more display devices are used and the pointer display is restricted on the middle display device, when a user operation is performed, the pointer may move from the first display device to the third display device and be displayed. In this case, the user is likely to lose track of the pointer's position.

[0091] Accordingly, the processor (130) cannot use the pointer function, but can control the display (110) to display a virtual pointer (610) that can check the current pointer location.

[0092] In this case, the processor (130) may apply a blinking effect to the virtual pointer (610) to clearly indicate to the user that the pointer display is restricted on the display device (100), or may control the display (110) to repeatedly display a graphic object (e.g., an X mark) indicating that the pointer cannot be used and the virtual pointer (610) in cross-section or display them together on one side of the virtual pointer (610).

[0093] Figure 7 illustrates a case where a graphic object is expressed in the form of a marker (710). A marker (710) refers to a graphic object that is displayed on at least one of the upper, lower, left, and right borders of the screen of a display device (100) and can move along the border.

[0094] As illustrated in FIGS. 7 to 9, when information including the display coordinates of a pointer is received from an external display device (200) through a communication unit (120), and the display device (100) is in a state where pointer display is restricted, the processor (130) may display a marker (710) on at least one of the upper, lower, left, and right border portions of the content being displayed on the display (110). In this case, when the display coordinates of the pointer change, the processor (130) may move the position of at least one marker (710) according to the display coordinates.

[0095] According to FIG. 7, when a pointer enters through the left side of the display device (100), the processor (130) displays a marker (710) at a height corresponding to the y-axis coordinate value among the coordinate values ​​of the pointer. In this state, when the pointer moves to point K, the processor (130) moves and displays the marker (710) at a height corresponding to the y-axis coordinate value among the coordinate values ​​of point K. That is, instead of displaying the actual position of the pointer on the screen, the processor (130) uses a marker (710) that moves along the border to enable the user to know where the pointer is on the screen.

[0096] Since the movement position of the pointer is within a preset threshold value on the x-axis from the left edge of the display device (100) into which the pointer has entered, the processor (130) can control the display (110) so that the marker (710) moves up and down only in the y-axis direction of the left edge according to the movement of the pointer.

[0097] If the position K of the pointer is located less than the critical distance from the left border corresponding to 0 on the x-axis, the position of the marker (710) moves up and down only along the left border according to the y-axis value among the positions of the pointer.

[0098] In FIG. 7, when the actual position k of the pointer falls beyond a threshold distance on the x-axis with respect to the left edge, the processor (130) can move and display the marker (710) to at least one of the upper edge and the lower edge. When the y-axis is closer to the upper side with respect to the center of the screen area, the processor (130) can display the marker (710) on the upper edge, and thereafter, move the marker (710) in the horizontal direction according to the movement of the pointer's position. In the above embodiment, the position of the pointer can be intuitively notified to the user using one marker, but this is merely an example, and the display position and number of markers can be variously modified.

[0099] For example, it could be implemented by displaying one marker each in the horizontal and vertical directions, so that the user can see that their intersection is the actual location of the pointer.

[0100] According to FIG. 8, when a pointer enters through the left side of the display device (100), the processor (130) displays markers (810, 820) at positions corresponding to the x-axis value and y-axis value corresponding to the entry point, respectively. The processor (130) can control the display (110) to move the first marker (810) displayed on the left edge portion in the vertical direction and the second marker (820) displayed on the upper edge portion in the horizontal direction.

[0101] Accordingly, if the pointer has moved to point K, the processor (130) can control the display (110) to move the second marker (820) according to the x-axis value corresponding to point K and to move the first marker (810) according to the y-axis value corresponding to point K. By visually identifying the positions of the first marker (810) and the second marker (820), the user can intuitively know that the actual pointer is located at the intersection of the virtual vertical lines extending from the markers (810, 820).

[0102] Fig. 9 illustrates a state in which a first marker and a second marker (910, 920) are displayed on the upper and lower edges, respectively. According to Fig. 9, when a pointer enters the screen of the display device (100), the processor (130) controls the display (110) to display a first marker and a second marker (910, 920) on the upper and lower edges, respectively. The first marker and the second marker (910, 920) may be arranged to face each other with respect to the center of the screen so as to have the same x-axis value.

[0103] The processor (130) may control the display (110) to simultaneously move the positions of the first marker and the second marker (910, 920) along the upper and lower edges to positions corresponding to the actual positions of the pointer as the actual position K point of the pointer moves. In addition, according to an embodiment, the first and second markers (910, 920) may be displayed on the left and right edges and implemented to move simultaneously in the upper and lower directions.

[0104] FIGS. 10 to 15 are diagrams for explaining the operation of a display device according to various embodiments of the present disclosure. Specifically, FIGS. 10 to 15 illustrate a case in which the entire screen of a display (110) in a display device (100) is divided into multiple split screens and used. The processor (130) can display screens of different content sources for each of the multiple split screens. For example, a PC screen can be displayed on a first split screen (1010), and a console game screen can be displayed on a second split screen (1020). FIGS. 10 to 15 illustrate a case in which a pointer moves to a split screen in which pointer display is restricted among these split screens.

[0105] When a user operation for splitting the screen of the display device (100) is input, the processor (130) can split the entire screen of the display (110) into multiple parts and display different screens in each of the split areas. In the present disclosure, the screens of each of the split areas are referred to as split screens. In addition, the processor (130) can control the display (110) to display a pointer at a point within one of the split screens among the entire screens of the split display (110).

[0106] When a user operation is input to move a pointer displayed in one of a plurality of split screens to another split screen where pointer display is restricted, the processor (130) can control the display (110) to display a graphic object indicating that the other split screen is in a state where pointer display is restricted.

[0107] As illustrated in FIG. 10, when the pointer (1011) moves from the first split screen (1010) to another split screen where pointer display is restricted, i.e., the second split screen (1020), the processor (130) can control the display (110) to display a graphic object.

[0108] A graphic object may include a display effect (1030) and a guide message (1040) that can visually inform the user of the display limitation status of the pointer. FIG. 10 illustrates a display effect (1030) in which the border portion of the second split screen (1020) blinks, but is not limited thereto.

[0109] The processor (130) can control the display (110) to display the pointer (1011) as if it is bouncing while remaining at the edge of the first split screen (1010). Accordingly, the user can intuitively know that the pointer (1011) cannot move to the second split screen (1020).

[0110] According to FIG. 11, when a user operation is input to move a pointer displayed on a first split screen (1110) among the split screens of the display device (100) to a second split screen (1120) in which pointer display is restricted, the processor (130) can control the display (110) to display a graphic object that replaces the pointer on the second split screen (1120). FIG. 11 illustrates a case in which a virtual pointer (1130) is displayed. The virtual pointer (1130) may have some or all of its functions restricted compared to a normal pointer. When some functions are supported, when a user inputs a control operation using an input device, the processor (130) can control the display (110) to display a user menu (1140) that can be selected using the input device.

[0111] For example, when a user inputs a control signal through a right-click or wheel operation of a mouse while a virtual pointer (1130) is displayed on a second split screen (1120) where pointer display is restricted, the processor (130) can control the display (110) to display a user menu (1140) that can be controlled by the user on the second split screen (1120).

[0112] Meanwhile, when a user clicks the left mouse button on the second split screen (1120) where the pointer display is limited, the processor (130) may control the display (110) to display a tooltip or pop-up window that guides the user to available information within the second split screen (1120).

[0113] In FIGS. 12 to 15, the entire screen of the display (110) is divided into three screen areas, and among the divided screen areas, two screen areas located on either side are areas where pointer display is possible, and the area located in the middle represents a screen area where pointer display is restricted.

[0114] For example, according to FIG. 12, the display (110) is divided into three screen areas, and different split screens can be displayed for each area. Among the divided screen areas, the first screen area (1210) and the third screen area (1230) are areas where pointer display is possible, and the second screen area (1220) represents a screen area where pointer display is restricted.

[0115] In the past, when a user attempted to move a pointer from a first screen area (1210) where pointer display is possible to a third screen area (1230) where pointer display is possible, the pointer was not displayed in the second screen area (1220) where pointer display was restricted, so the user was unable to recognize the current position of the pointer and thus was unable to smoothly move the pointer.

[0116] According to one or more embodiments of the present disclosure, when a user operation is input to move a pointer (1201) displayed in a first region (1210) where pointer display is possible among a plurality of divided screen regions to a second region (1220) where pointer display is restricted, the processor (130) can control the display (110) to display a graphic object replacing the pointer (1201) on the second region (1220) where pointer display is restricted.

[0117] For example, FIG. 12 shows a virtual pointer (1240) applied to a graphic object.

[0118] Similarly, in FIG. 13, among the three screen areas divided into three, the first screen area (1310) and the third screen area (1330) are areas where pointer display is possible, and the second screen area (1320) represents a screen area where pointer display is restricted.

[0119] In this case, when a user inputs a user operation to move a pointer (1301) displayed in a first area (1310) where pointer display is possible among multiple divided screen areas to a third area (1330) where pointer display is possible through a second area (1320) where pointer display is restricted, the processor (130) may control the display (110) to display a semi-transparent arrow (1340) replacing the pointer (1301) on the second area (1320) where pointer display is restricted.

[0120] The virtual pointer (1240) and the translucent arrow (1340) are displayed translucently in the screen area where the pointer display is restricted, and can be moved according to the operation of the input device (10), and the function of the pointer may be restricted.

[0121] However, when a user attempts to manipulate a pointer in a screen area where pointer display is restricted, the processor (130) may control the display (110) to display a tooltip or pop-up window that guides the user to available information in the area where pointer display is restricted, as described above.

[0122] Accordingly, when a user attempts to perform an operation to move a pointer from a first screen area (1210, 1310) where pointer display is possible to a third screen area (1230, 1330) where pointer display is possible, the pointer can smoothly pass through the second screen area (1220, 1320) where pointer display is restricted and enter the third screen area (1230, 1330), and at this time, the user can check the path along which the pointer moves in the second screen area (1220, 1320) where pointer display is restricted.

[0123] Among the three screen areas divided in FIGS. 14 and 15, the first screen area (1410, 1510) and the third screen area (1430, 1530) are areas where pointer display is possible, and the second screen area (1420, 1520) represents a screen area where pointer display is restricted.

[0124] When a user inputs a user operation to move a pointer (1401, 1501) displayed in a first area (1410, 1510) of a screen divided into multiple areas where pointer display is possible, through a second area (1420, 1520) where pointer display is restricted, to a third area (1430, 1530) where pointer display is possible, the processor (130) may control the display (110) to display a border blinking display (1440) on the screen to indicate that the pointer cannot be used in the second area (1420, 1520) where pointer display is restricted, or to display a marker (1450) that replaces the pointer (1401, 1501).

[0125] In FIG. 14, a marker (1450) indicates a point in time when a pointer (1401) enters a second area (1420) where pointer display is restricted, and FIG. 15 indicates a marker (1540) where a pointer (1501) located in a second area (1520) where pointer display is restricted has moved its position beyond a preset threshold value from the left border, which is the pointer entry direction.

[0126] When a user operation is input to move a pointer displayed in one of the divided screen areas of the display (110) to another area where pointer display is restricted, as in the above-described FIGS. 7 to 9, the processor (130) may display at least one marker that moves along at least one of the upper, lower, left, and right borders of the other area. Here, the processor (130) may move the position of at least one marker according to the operating direction and distance of the input device (10).

[0127] FIGS. 16 and 17 are diagrams for explaining pointer movement display effects between display devices according to various embodiments of the present disclosure. As shown in FIGS. 16 and 17, when a user operation for moving a pointer (1610) from an external display device (200) to a display device (100) is input and the display device (100) is capable of displaying a pointer, the processor (130) can control the display (110) to display a graphic object to notify the user that the pointer's location has moved to another device at the point where the pointer (1610) enters the display device (100).

[0128] According to FIG. 16, the processor (130) can control the display (110) to display a highlight (1620) on a border portion corresponding to the movement direction of the pointer (1610) among the upper, lower, left, and right border portions of the external display device (200) and the display device (100) at the point of movement when the pointer (1610) enters the display device (100) from the external display device (200).

[0129] Alternatively, when a user operation is input to move a pointer (1610) displayed on an external display device (200) according to an operation of an input device (10), the processor (130) may control the display (110) to display various graphic effects, such as a screen border fluctuating or bulging for a certain period of time and then returning to the edge area of ​​the display (110) on the edge portion of the external display device (200).

[0130] In this case, pointer coordinate information can be received from an external display device (200) through the communication unit (120).

[0131] As shown in the lower drawing of FIG. 16, when the pointer (1610) crosses a preset threshold from the boundary between screen areas, the processor (130) can control the display device (100) to display a lighting effect (1630) of the display device (100) to notify the user that the mouse operation target has changed.

[0132] Referring to FIG. 17, when a pointer (1710) enters the display device (100) from an external display device (200) and exceeds a preset threshold from the boundary between screen areas, the processor (130) may control the display (110) to display a border blinking effect of the display (110).

[0133] However, the present invention is not limited thereto, and the processor (130) may control the display (110) to display at least one of a highlight display, a border animation effect, a cursor animation effect, a virtual pointer, and a translucent icon added to the display (110) screen where the pointer is located to notify the user that the mouse operation target has changed.

[0134] FIGS. 18 to 21 are diagrams for explaining pointer movement display effects between screens according to various embodiments of the present disclosure. As shown in FIGS. 18 to 21, when a user inputs a user operation for moving a pointer between screens where pointer use is possible within a display device (100), the processor (130) may control the display (110) to visually indicate the screen area where the pointer is located at the time of movement when the pointer enters the target screen area, or to display a graphic object to notify the user that the mouse operation target has changed.

[0135] According to FIG. 18, both the split screen area (1810) and the screen area (1820) of the display device (100) represent screen areas where a pointer can be displayed. When a user inputs a user operation to move a pointer (1801) located in the screen area (1810) to the screen area (1820), the processor (130) can control the display (110) to display a border blinking effect (1830) in the screen area (1820) where the pointer (1801) is located.

[0136] Alternatively, the processor (130) may control the display (110) to display a virtual pointer (1840) or a translucent icon (1850) on the screen area (1820) where the pointer (1801) is located to visually indicate the screen area (1820) where the pointer (1801) is located at the point of pointer movement between screen areas where pointer use is possible.

[0137] According to FIG. 19, when a user inputs a user operation to move a pointer (1930) located on a screen (1910) where pointer use is possible to a screen (1920) where pointer use is possible, the processor (130) can control the display (110) to display an effect (1940) in which a part of the screen area (1910) flows into the screen area (1920) at the point where the pointer (1930) moves past the boundary of the screen area.

[0138] In this case, when the pointer (1930) crosses a preset threshold from the boundary between screen areas, the display (110) screen returns to the original normal screen as shown in the lower drawing of FIG. 19.

[0139] According to FIG. 20, when a user inputs a user operation to move a pointer (2030) located on a screen (2010) where pointer use is possible to a screen (2020) where pointer use is possible, the processor (130) can control the display (110) to display a graphic object to visually indicate the point of movement of the pointer (2030) at the boundary of the screen area at the point of movement when the pointer (2030) passes the boundary of the screen area.

[0140] In FIG. 20, the processor (130) controls the display (110) to display a graphic object in the shape of an ellipse (2040) at the boundary of the screen area when the pointer (2030) moves past the boundary of the screen area. Even in this case, when the pointer (2030) crosses a preset threshold from the boundary between the screen areas, the display (110) screen returns to the original normal screen, as shown in the lower drawing of FIG. 20.

[0141] According to FIG. 21, when a user inputs a user operation to move a pointer (2130) located on a screen (2110) capable of using a pointer to a screen (2120) capable of using a pointer, the processor (130) can control the display (110) to display a marker (2140) corresponding to the position of the pointer (2130) at the point of movement when the pointer (2130) passes the boundary of the screen area.

[0142] In addition, the processor (130) can control the display (110) to display a graphic object in the shape of an arc (2150) with the coordinate position of the screen boundary that the pointer (2130) first entered as the origin and the current coordinate position of the marker (2140) as the radius at the time when the pointer (2130) moves past the boundary of the screen area.

[0143] As shown in the rightmost drawing of Fig. 21, when the pointer (2130) crosses a preset threshold from the boundary between screen areas, the display (110) screen returns to the original normal screen.

[0144] In the present disclosure, embodiments that visually indicate the screen area where the pointer is located at the time of pointer movement between screens where pointer use is possible, or display a graphic object to notify the user that the target of mouse operation has changed, are not limited to the examples described above.

[0145] The processor (130) according to the present disclosure can control the display (110) to display a graphic object including a highlight display, a border blink display, a border animation effect, a cursor animation effect, a virtual pointer, a translucent icon, at least one marker moving along at least one of the upper, lower, left, and right borders of the screen area where the pointer is positioned, to inform the user that the mouse operation target has changed at the time of pointer movement between screens where the pointer can be used.

[0146] As described above, the display device (100) can easily identify the current position of the pointer and confirm the pointer control target screen even when the user moves the pointer to a screen area where pointer display is not possible.

[0147] FIGS. 22 to 26 are flowcharts for explaining a display method of a display device according to various embodiments of the present disclosure.

[0148] According to one or more embodiments, when the display device displays a pointer corresponding to the input device on a screen on an external display device to which the input device is connected, and the pointer moves off the screen due to movement of the input device, the display device receives information about the pointer from the external display device (S2210).

[0149] If the display device generates information about the display coordinates of the pointer in response to the input device's operation, the generated pointer coordinate information can be transmitted to the external display device. The display device and the external display device share the generated pointer coordinate information with each other, and the display device's screen and the external display device's screen are regarded as being connected to each other with continuous coordinates, and the pointer is displayed.

[0150] If the display device is in a state where pointer display is restricted, the display device displays a graphic object indicating the pointer display restriction state (S2220).

[0151] Even if the display device natively supports pointer use, if you use an application, streaming service, or program that does not support pointer use, pointer use may not be possible in that display screen area.

[0152] If the display device can display a pointer in the screen area indicated by the pointer coordinate information, it displays the pointer according to the pointer coordinate information. If the pointer display is restricted, it visually indicates that the pointer display is restricted, or displays a graphic object that replaces the pointer.

[0153] A graphic object may be displayed translucently on the display, move in response to the movement of the input device, and may include a virtual pointer that limits the functionality of the input device. A graphic object may also include a highlight that is added to the edge area of ​​the content being displayed.

[0154] According to FIG. 23, the display device receives information about a pointer from an external display device to which an input device is connected (S2210), and if the display device is in a state where pointer display is limited, it may display at least one marker on at least one of the upper, lower, left, and right borders of the content being displayed on the display (S2310).

[0155] Additionally, the display device can move at least one marker along at least one border according to the movement of the input device (S2320).

[0156] For example, the display device may display a marker on the content border in the direction the pointer entered when the pointer enters the display. Alternatively, the display device may generate markers on the upper and lower borders of the content when the pointer enters, and control the display so that the markers move along the upper and lower borders according to the display coordinate position of the pointer.

[0157] Alternatively, the display device may display a first marker on at least one of the upper and lower edges of the content and a second marker on at least one of the left and right edges of the content when a pointer enters the display device. In this case, the display device may control the display so that when the display coordinates of the pointer move, the first marker and the second marker move to a position where the virtual intersection of the first marker and the second marker corresponds to the display coordinates of the pointer.

[0158] The display device may control the display so that if the changed position of the pointer is within a preset threshold from the entered side, the marker is positioned at the entered border portion, and if the changed position of the pointer is greater than or equal to the preset threshold from the entered side, the marker moves to a position corresponding to the display coordinates of the pointer.

[0159] According to FIG. 24, the display device receives information about a pointer from an external display device to which an input device is connected (S2210), and when the display device is in a state where pointer display is restricted, the display device can display a graphic effect for a preset time on an edge portion of the display on the side of the external display device among the edge areas of the display (S2410).

[0160] In this case, the display device can display a graphic effect on the display edge portion in the pointer entry direction where the external display device is located based on pointer coordinate information received from the external display device.

[0161] The display device may highlight an edge portion of the external display device when the pointer enters the display, or may display a virtual pointer that replaces the pointer.

[0162] According to FIG. 25, when a user operation for screen splitting is input, the display device can divide the entire screen of the display into multiple split screens and display a pointer within one of the multiple split screens (S2510).

[0163] When a pointer displayed in one of the divided areas moves to another divided area where pointer display is restricted, the display device can display a graphic object indicating a pointer display restriction state on the other area (S2520).

[0164] These graphic objects may include display effects and guide messages that visually inform the user of the pointer's display constraints.

[0165] According to FIG. 26, the display device displays a pointer within one of a plurality of split screens (S2510), and when the pointer displayed in one of the split areas moves to another split area where pointer display is restricted, the display device can display at least one marker on at least one of the upper, lower, left, and right borders of the other split area (S2610).

[0166] The display device can move at least one marker along at least one border according to the movement of the input device (S2620).

[0167] For example, the display device can move the position of a marker depending on the direction in which the pointer enters the display and the distance from the border surface of the content into which the pointer enters.

[0168] Various embodiments of these graphic objects have been specifically described in the display device described above, so further description is omitted.

[0169] Meanwhile, in the above-described embodiments, the case where multiple display devices are connected and used and the case where multiple split screens are displayed on one display device are illustrated and described separately, but at least some of these embodiments may be combined with each other.

[0170] For example, when a first display device (100) or a second display device (200) of FIG. 1 displays multiple split screens (101, 102, 103) as in FIG. 2, if there is a screen among the split screens where pointer display is restricted, the device can provide various types of graphic objects as described above when the pointer moves into that screen. Alternatively, embodiments such as FIG. 2 may be implemented to be executed independently on a single display device that is not connected to other display devices.

[0171] In addition, although the above various embodiments have described cases where graphic objects are used to be displayed visually, in addition, the location of the pointer may be notified to the user using acoustic information such as various signal sounds or voice messages.

[0172] Meanwhile, according to another embodiment of the present invention, when a user shakes the input device (10), presses a specific button, or inputs a specific voice input or motion input while the pointer of the input device (10) is positioned within the display screen of any device, an operation may be performed to immediately return the pointer to a default position on the input device (10) or on a terminal device to which the input device (10) is connected.

[0173] According to the above various embodiments, when connected to multiple external display devices or providing multiple split screens, the position of the pointer displayed when the user moves the input device can be easily determined.

[0174] Additionally, a non-transitory readable medium storing program codes or computer commands for executing the various display methods described above may be provided.

[0175] These non-transitory computer-readable media, when mounted on a specific device, allow the device to perform display methods according to various embodiments. A non-transitory computer-readable medium refers to a medium that permanently stores data and can be read by the device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specific examples of non-transitory computer-readable media include CDs, DVDs, hard disks, Blu-ray discs, USBs, memory cards, and ROMs.

[0176] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
