Through the output unit (250), the user can recognize whether the user input unit (230) is being operated or whether the display device (100) is being controlled.

[0088] For example, the output unit (250) may be equipped with an LED module (251) that lights up when the user input unit (230) is operated or a signal is transmitted and received with the display device (100) through the wireless communication unit (220), a vibration module (253) that generates vibration, a sound output module (255) that outputs sound, or a display module (257) that outputs an image.

[0089] In addition, the power supply unit (260) supplies power to the remote control device (200), and can reduce power waste by stopping the power supply when the remote control device (200) is not moved for a predetermined period of time. The power supply unit (260) can resume the power supply when a predetermined key provided in the remote control device (200) is operated.

[0090] The storage unit (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200). If the remote control device (200) wirelessly transmits and receives signals through the display device (100) and the RF module (221), the remote control device (200) and the display device (100) transmit and receive signals through a predetermined frequency band.

[0091] The control unit (280) of the remote control device (200) can store and reference information regarding the frequency band, etc., that can wirelessly transmit and receive signals with the display device (100) paired with the remote control device (200), in the storage unit (270).

[0092] The control unit (280) controls all matters related to the control of the remote control device (200). The control unit (280) can transmit a signal corresponding to a predetermined key operation of the user input unit (230) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor unit (240) to the display device (100) via the wireless communication unit (220).

[0093] Additionally, the voice acquisition unit (290) of the remote control device (200) can acquire voice.

[0094] The voice acquisition unit (290) may include at least one microphone (291) and may acquire voice through the microphone (291).

[0095] Next, Figure 4 is described.

[0096] FIG. 4 shows an example of utilizing a remote control device according to an embodiment of the present disclosure.

[0097] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display unit (180).

[0098] The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display unit (180) of the display device (100) corresponds to the movement of the remote control device (200). As shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space, so the remote control device (200) can be called a space remote control.

[0099] Figure 4 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display unit (180) of the display device (100) also moves to the left in response.

[0100] Information about the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100). The display device (100) can calculate the coordinates of the pointer (205) from the information about the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

[0101] Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display unit (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display unit (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.

[0102] Conversely, when the user moves the remote control device (200) closer to the display unit (180), the selection area within the display unit (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.

[0103] Meanwhile, when the remote control device (200) moves away from the display unit (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display unit (180), the selection area may be zoomed in.

[0104] In addition, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device (200) moves away from or toward the display unit (180), up, down, left, and right movements may not be recognized, and only forward and backward movements may be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves in accordance with the up, down, left, and right movements of the remote control device (200).

[0105] Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).

[0106] Meanwhile, the pointer in this specification refers to an object displayed on the display unit (180) in response to the operation of the remote control device (200). Therefore, objects of various shapes other than the arrow shape illustrated in the drawing can be used as the pointer (205). For example, the pointer may be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) may be displayed corresponding to one point on the horizontal or vertical axis on the display unit (180), or may be displayed corresponding to multiple points such as lines or surfaces.

[0107] FIG. 5 (a) and FIG. 5 (b) are drawings for explaining the horizontal mode and vertical mode of a stand-type display device according to an embodiment of the present disclosure.

[0108] Referring to (a) and (b) of FIG. 5, a stand-type display device (100) is illustrated.

[0109] A shaft (103) and a stand base (105) can be connected to the display device (100).

[0110] The shaft (103) can connect the display device (100) and the stand base (105). The shaft (103) can extend vertically.

[0111] The lower end of the shaft (103) can be connected to the edge of the stand base (105).

[0112] The lower end of the shaft (103) can be rotatably connected to the periphery of the stand base (105).

[0113] The display device (100) and shaft (103) can rotate around a vertical axis with respect to the stand base (105).

[0114] The upper part of the shaft (103) can be connected to the rear of the display device (100).

[0115] The stand base (105) can serve to support the display device (100).

[0116] The display device (100) may be configured to include a shaft (103) and a stand base (105).

[0117] The display device (100) can rotate around the point where the upper part of the shaft (103) and the rear part of the display (180) meet.

[0118] Figure 5 (a) shows that the display (180) operates in a landscape mode in which the horizontal length is greater than the vertical length, and Figure 5 (b) shows that the display (180) operates in a landscape mode in which the vertical length is greater than the horizontal length.

[0119] The user can move the stand-type display device (100). That is, unlike a fixed device, the stand-type display device (100) has improved mobility, so the user is not restricted by the placement location.

[0120] Control of a display device (100) using a remote control device (200) is becoming more common. In the case of a set-top box (STB) connected to a display device (100), a remote control device search function is implemented with the concept of an always connection through direct advertising (ADV). In this case, even if the set-top box (STB) is off, the remote control device repeats direct advertising (Direct ADV) on its own. In this process, when the set-top box (STB) is turned on, the remote control device (200) reconnects with the set-top box (STB) through the repeating direct advertising (Direct ADV) and maintains the connection state.

[0121] Meanwhile, depending on the type of remote control device (200), for example, a remote control device (200) that can support a pointing function based on a gyro sensor has a higher current consumption than a remote control device (200) that does not. Therefore, when the always-connection concept is applied to such a remote control device (200), the usable time of the remote control device (200) is bound to be significantly reduced due to the high current consumption.

[0122] A typical remote control device, in an always-on state, typically consumes about 500uA to 1mA of current. However, a remote control device (200) equipped with various sensors and a wheel may have a higher standby current than a typical remote control device. As previously mentioned, this can shorten the usable time of the remote control device (200).

[0123] In the present disclosure, in the above-described situation, pairing can be performed between the remote control device (200) and the display device (100) only when a condition is satisfied, for example. Meanwhile, the condition in the above-described case may include, for example, a case where a remote control device search function is activated. This remote control device search function may be activated by an input such as a physical key (or button) (or local key) provided on the rear of the display device (100), remote voice recognition, etc. Therefore, according to the present disclosure, by controlling whether the display device (100) is connected to the remote control device (200), unnecessary power consumption of the remote control device (200) can be reduced, and further, the usable time of the remote control device (200) can be extended compared to the past.

[0124] Meanwhile, unlike the packet when pairing with the display device (100) for the first time, the remote control device (200) transmits an advertising packet so that it can be scanned only by the existing paired TV, thereby preventing malfunctions that may occur during the pairing process to find the remote control device (200).

[0125] According to at least one of the various embodiments of the present disclosure, before the display device (100) and the remote control device (200) are paired, a first data packet is received, and after the pairing, a second packet is received, so that the second packet is scanned only by the display device (100), and when an input for a remote control device search function is obtained, a pairing operation can be performed based on the second data packet.

[0126] In relation to this, the remote control device (200) can be equipped with an additional buzzer and advertise periodically in relation to the remote control device search function, but the display device unit can be controlled to search for the remote control device (200) while minimizing the increase in current consumption by implementing advertising packet filtering so that it does not connect when there is no request for the search function, thereby connecting only when the user requests to search for the remote control.

[0127] FIG. 6 is a block diagram illustrating a connection control operation between a display device and a remote control device according to one embodiment of the present disclosure.

[0128] Referring to FIG. 6, at least one of a server (300), a terminal (400), or an external device (500) may be further involved in the connection control operation between the display device (100) and the remote control device (200).

[0129] Here, the display device (100) may be equipped with, for example, a memory and a processor. Here, the memory may have the same configuration as the memory (140) of FIG. 1. In addition, the processor may have the same configuration as, or include, or be included in, the controller (170) of FIG. 1.

[0130] The remote control device (200) can transmit packets to the display device (100). At this time, the packets can be transmitted periodically.

[0131] When a packet is received from a remote control device (200), the display device (100) can check whether there is a pairing history with the remote control device (200). If, as a result of the check, there is no pairing history with the remote control device (200), i.e., if it is the first pairing request, the display device (100) can perform a pairing operation with the remote control device (200).

[0132] The present disclosure relates particularly to cases where a user wishes to locate a remote control device when the location of the device is unknown. As previously mentioned, conventional remote control device locating has been accomplished through the remote control device itself or a set-top box (STB), but this has presented the aforementioned problems. In particular, remote control devices that incorporate sensors or wheels, etc., have high standby currents, making it necessary to reduce unnecessary power consumption.

[0133] In this context, various embodiments of the present disclosure are described.

[0134] The remote control device (200) can continuously transmit packets periodically. At this time, transmitting packets from the remote control device (200) can be viewed as a broadcast.

[0135] The display device (100) can receive packets from the remote control device (200) even when power is not supplied at all, for example, in a standby state.

[0136] Unlike the conventional method, the display device (100) according to one embodiment of the present disclosure can connect to the remote control device (200) only when a condition is satisfied when a packet is received from the remote control device (200), and can ignore or filter the packet received from the remote control device (200) otherwise.

[0137] In the present disclosure, conditions include, for example, whether a remote control device search function is requested and activated as described above.

[0138] In the above, the remote control device search function can be requested and activated, for example, through a hard function key or physical function key provided on the display device (100), a virtual function key provided on the display panel, a terminal (400), or an external device (500). In the above, the remote control device search function through the terminal (400) can, for example, receive a signal including an input selected through an application screen executed in relation to the remote control device on the terminal (400) through the server (300) or directly, and activate the remote control device search function by identifying the signal. In addition, the remote control device search function through the external device (500) can, for example, when the external device is a voice recognition speaker or microphone, receive a voice input related to a user's request for the remote control device search function, and transmit a corresponding signal to the display device (100) through the server (300) or directly according to the received voice input, thereby activating the remote control device search function in the display device (100).

[0139] Figures 7 and 8 are flowcharts illustrating the connection operation of a display device (100) and a remote control device (200) according to embodiments of the present disclosure.

[0140] FIG. 7 may represent a connection operation during the initial pairing process between a display device (100) and a remote control device (200) or a connection operation in a general situation.

[0141] Additionally, FIG. 7 is described from the perspective of the display device (100) or the processor of the display device (100), but is not limited thereto.

[0142] The remote control device (200) related to the present disclosure can perform, for example, the following two types of advertising. One may be, for example, an undirect advertising (Un-direct ADV) type, and the other may be a direct advertising (Direct ADV) type. However, the present disclosure is not limited thereto.

[0143] As mentioned above, the undirect advertising type refers to packet advertising transmitted when, for example, the remote control device (200) is not paired with the display device (100), and this may be a type of broadcast concept. Therefore, in the undirect advertising type, since the packet is not advertised only to a specific device, it can be connected to all devices that receive the broadcast packet.

[0144] On the other hand, the direct advertising type may indicate a case where a packet is advertised when, for example, it has already been paired with a display device (100). In the case of the direct advertising type, the advertised packet may include, for example, a link key, so that it can only be connected with a display device (100) with which it has a connection history.

[0145] Referring to FIG. 7, the remote control device (200) can attempt to connect to the display device (100) when a key or sensor is moved. However, if the location of the remote control device (200) is unknown, the remote control device (200) must be able to attempt to connect on its own in order to find the remote control device. In other words, for the remote control device search function, the remote control device (200) can advertise to be able to always connect to the display device (100) (S110). At this time, the remote control device (200) can only perform advertising at a preset cycle, and the preset cycle can be arbitrarily changed.

[0146] The same applies even if the remote control device (200) is located near the user or the display device (100). This is because the remote control device (200) does not recognize its own state.

[0147] In addition, since the remote control device (200), which is basically a slave device, cannot know whether the power of the display device (100), which is a master device, is on or off, the remote control device (200) can continue to advertise packets.

[0148] If the display device (100), which is the master device, is turned off, the connection between the master and the slave continues to fail. Afterwards, if the display device (100), which is the master device, is turned on, the remote control device (200) that continues to advertise can be connected to the display device (100) (Connection Success) (S120 / S130).

[0149] If no movement is detected for a preset period of time after the remote control device (200) successfully connects to the display device (100), the remote control device (200) may automatically disconnect from the display device (100). In this case, the same may apply even if control of the display device (100) continues by receiving voice input through an application on the terminal (400) or an external device (500).

[0150] Therefore, since the remote control device (200) must advertise again to perform the remote control device search function, connection and disconnection may be performed repeatedly.

[0151] According to an embodiment, the remote control device (200) may broadcast a control signal to enable the display device (100) to find the remote control device (200) or to advertise the remote control device (200), for example, when a user activates a remote control device search function through the display device (100).

[0152] Therefore, since the remote control device (200) is like an always-connected device except when it is temporarily disconnected from the display device (100), the current consumption of the remote control device (200) continues to increase, and as a result, the usable time of the remote control device (200) is bound to decrease.

[0153] In the above, the disconnection may be performed not by the remote control device (200) itself, but under the control of the display device (100). In addition, the display device (100) may also be controlled by the server (300).

[0154] FIG. 8 is a drawing illustrating a detailed operation of a connection between a display device (100) and a remote control device (200) according to one embodiment of the present disclosure.

[0155] Referring to FIG. 8, the remote control device (200) can advertise a packet to the display device (100) (S210).

[0156] When a packet is advertised from a remote control device (200), the display device (100) can determine whether it is on (S220).

[0157] If the display device (100) is not turned on, it can wait to receive the next packet advertised from the remote control device (200).

[0158] On the other hand, if the display device (100) is in the on state, it can then determine whether the condition is satisfied (S230). Here, the condition is, as described above, for example, whether the remote control device search function is activated.

[0159] The display device (100) may reject a connection with the remote control device (200) if, as a result of the S230 operation judgment, the display device (100) is turned on but the preset conditions are not yet satisfied. At this time, the connection rejection may be achieved, for example, by the display device (100) ignoring or filtering the packet advertised by the remote control device (200). Alternatively, the display device (100) may directly transmit a control signal including a control command indicating a connection rejection to the remote control device (200) that advertised the packet in order to reject the connection.

[0160] On the other hand, if the display device (100) is turned on and the preset conditions are satisfied as a result of the S230 operation judgment, the display device (100) can approve the connection with the remote control device (200) (S240) and perform the connection (connection success) (S250).

[0161] If the display device (100) is successfully connected to a remote control device (200) that advertised a packet through operation S250, the display device (100) can transmit a control signal to enable the user to find the connected remote control device (200) in accordance with the condition, i.e., the remote control device search function (S260).

[0162] Here, the control signal may include a control command that controls or requests the remote control device (200) to output sound. The control signal may include a control command that commands or requests the remote control device (200) to transmit at least one of its own battery status, location information related to location identification information, etc. to the display device (100).

[0163] Accordingly, the remote control device (200) can output, for example, an alarm (S270). To this end, the remote control device (200) may include an output unit (not shown). In this case, the output unit may include, for example, a buzzer.

[0164] Meanwhile, in cases where the remote control device (200) does not transmit a simple alarm signal through a buzzer, it may output information on the display device (100) or output information through a terminal (400) or an external device (500).

[0165] Afterwards, the remote control device (200) can perform normal operation (S280).

[0166] And the remote control device (200) can maintain the connection with the display device (100) (S290) and then release the connection (S300).

[0167] Maintaining the connection as described above may be accomplished when a user input is obtained on the remote control device (200) within a preset time or movement of the remote control device (200) is detected. Conversely, the connection between the display device (100) and the remote control device (200) may be disconnected when no user input is obtained for a preset time or more or movement of the remote control device (200) is detected.

[0168] Although in Fig. 8, the subject of connection maintenance and connection release is described as a remote control device (200), at least one of the two may be performed under the control of the display device (100).

[0169] In the above, when the connection between the display device (100) and the remote control device (200) is disconnected, the remote control device (200) advertises a packet again as described above, and the display device (100) can receive it.

[0170] The above-described operation can be performed repeatedly.

[0171] In FIGS. 7 and 8, some operations of the display device (100) may not be determined or performed by the display device (100) itself, but may be performed based on control commands obtained from at least one of the server (300), the terminal (400), and the external device (500).

[0172] FIGS. 9 and 10 are diagrams illustrating an advertising filter policy according to an embodiment of the present disclosure.

[0173] Figure 9 shows the definition of the advertising filter policy (Advertising_Filter_Policy) related to the present disclosure.

[0174] At this time, FIG. 9 may define an advertising filter policy in relation to the aforementioned undirect advertising packet between the display device (100) and the remote control device (200).

[0175] Referring to Figure 9, the parameter values ​​of the advertising filter policy are defined from 0x00 to 0x03, for example, and the remaining values ​​are reserved for future use.

[0176] When the advertising filter policy parameter value is 0x00, the display device (100) can process scan and connection requests from all devices by default. In this case, all devices may include a remote control device (200). Additionally, all devices may also include devices not included in the white list described below.

[0177] In other words, the remote control device (200) can advertise that the advertising filter policy can be connected to all display devices belonging to the network when pairing by transmitting an undirect advertising packet (0x00).

[0178] As described above, the remote control device (200) can change the parameter value from 0x00 to 0x03 to perform or prepare for the remote control device search function after pairing with the display device (100) by transmitting an undirect advertising packet with the parameter value set to 0x00. Accordingly, the parameter of the packet periodically undirectly advertised from the remote control device (200) thereafter can be 0x03. According to one embodiment, this parameter value can be maintained until the connection is disconnected or pairing is interrupted.

[0179] That is, both the display device (100) and the remote control device (200) change the advertising filter policy to 0x00, and after the change, only the paired display device (100) can be scanned and connected. To this end, the display device (100) can create and store a white list for paired devices. At this time, the white list includes the paired remote control device (200).

[0180] In this regard, when the remote control device (200) is paired with the display device (100), the MAC address of the display device can be registered in the white list. On the other hand, in this case, in the case of direct advertising, the advertising filter policy may not be used.

[0181] If the parameter value of the advertising filter policy is 0x01, connection requests can be received from all devices, but scan requests can be received and processed only from devices included in the white list.

[0182] Additionally, if the parameter value of the advertising filter policy is 0x02, scan requests can be received from all devices, but connection requests can be received and processed only from devices included in the white list.

[0183] In connection with the present disclosure, advertising settings can be changed based on the remote control device (200). All advertising filter policies are non-direct advertising, and a parameter value of 0x00 can be used for initial pairing, and 0x03 can be used to enable scanning and connection only to paired devices when the remote control device search function is activated.

[0184] In this way, the present disclosure can add an advertising type related to a remote control device search function.

[0185] That is, when the remote control device search function is set by defining the parameter value 0x03, an advertising filter policy can be set and applied (i.e., a white list can be configured) so that scanning and connection processing are only possible on the paired display device (100). Accordingly, even if the remote control device (200) performs non-direct advertising, it is possible to control so that only the paired display device (100) can be connected to the remote control device (200).

[0186] As mentioned above, when implementing remote control device discovery through direct advertising, advertising filter policies may not apply because connections are unconditionally established. Therefore, the effectiveness of remote control device discovery through direct advertising may be reduced.

[0187] By including specific information in the advertising data packet, the display device (100) can determine whether the data packet is an advertising data packet related to the remote control device search function and reject the connection if the condition, i.e., the remote control device search function is not activated. Here, rejection may be concepts such as ignoring or filtering, as described above. If the data packet is advertised without the corresponding information, it is direct advertising and can therefore be connected in the same manner as in the conventional method.

[0188] The remote control device search function may be activated by at least one of a specific key input, a combination of special keys, utterance of a remote activation word, etc., in which case the display device (100) may scan and then connect to the remote control device (200).

[0189] Figure 10 (a) represents passive scan, and Figure 10 (b) represents active scan.

[0190] Referring to (a) of Fig. 10, manual scanning represents a case where only a direct advertising device can be connected. The advertiser (i.e., a remote control device) unilaterally advertises a data packet (ADV_IND) including an indicator to a scanner (i.e., a display device (100)).

[0191] On the other hand, referring to (b) of FIG. 10, active scanning indicates that all non-direct advertising devices are connectable. The advertiser (remote control device (200)) advertises a data packet (ADV_IND) including an indicator, and the scanner (display device (100)) transmits a scan request (SCAN_REQ) to the advertiser when the advertised data packet (ADV_IND) is received, and the advertiser can return a scan response (SCAN_RSP) in response.

[0192] In this disclosure, the operation when changing the advertising filter policy is described as follows.

[0193] The remote control device (200) can perform a scan response whenever another device makes a scan request when the parameter value is set to 0x00. Here, the other device may include, for example, a display device (100).

[0194] When the parameter value of the remote control device (200) is set to 0x03, it may not respond to a scan even if another device makes a scan request.

[0195] Since a remote control device (200) that is performing undirect advertising is searched, an unpaired display device can also make a scan request.

[0196] However, the remote control device (200) may not respond to the scan because the display device that requested the scan is not a MAC address registered in the white list.

[0197] That is, even if a scan request, connection request, etc. is received, the remote control device (200) can only respond to devices registered in the white list.

[0198] Meanwhile, when an event or interrupt such as a key, motion, wheel, etc. occurs in the remote control device (200) while undirect advertising is being performed for the remote control device search function, this corresponds to direct advertising, so a connection operation can be performed immediately and normal operation can be performed.

[0199] In the present disclosure, for the remote control device search function, the remote control device (200) advertises at a preset cycle so that it can be connected to the display device (100) at any time.

[0200] In this case, if the display device (100), which is the master device, is turned off, the connection will continue to fail. Afterwards, when the display device (100) is turned on, the display device (100) can be connected to the advertising device from that time on.

[0201] The display device (100) can be configured to check whether a special key related to the remote control device search function among local keys (e.g., pressing the volume button for more than 5 seconds) is activated or the remote control device search function is activated through remote voice recognition such as a remote activation word, for example, and to reject the connection if the special key is N (if the key is not pressed), and to allow the connection for a predetermined period of time if the key is Y (if the key is pressed). Here, the predetermined period of time can be set to, for example, 15 seconds to 1 minute, but is not limited thereto and can be arbitrarily changed.

[0202] Meanwhile, in the above, when speaking about the remote control device search function, for example, through long-distance voice recognition, the display device (100) allows the connection. The spoken words may include, for example, “Find the remote control device” or “Where is the remote control device?”

[0203] When the display device (100) approves the connection with the remote control device (200), the display device (100) can transmit an alarm signal, for example, a buzzer enable command (Buzzer Enable CMD), to the remote control device (200), and accordingly, the remote control device (200) can sound a buzzer to reveal the location of the remote control device.

[0204] A user can identify and find the location of the remote control device (200) by the buzzer sound of the remote control device (200). When the user lifts the remote control device (200) by hand and moves it, the search for the remote control device is recognized as complete due to an event or interrupt that occurs at this time, and the buzzer can be stopped. At this time, the buzzer of the remote control device (200) can be stopped, for example, by generating and transmitting a buzzer stop command from the display device (100) after receiving and identifying the interrupt, thereby stopping the buzzer of the remote control device (200).

[0205] When the remote control device search is completed, the remote control device (200) operates in the same manner as before.

[0206] In relation to this, FIG. 13 is a drawing showing an example of a user interface provided by a display device when a remote control device search function is activated according to one embodiment of the present disclosure.

[0207] In (a) of Fig. 13, information on the expected positions of the display device (100) and the remote control device (200) can be provided through a pop-up window on the display or in an area of ​​the display. The same applies to (c) of Fig. 13. However, in the case of (c) of Fig. 13, information on the expected positions of the remote control device (200) can be provided only on the front panel of the display device (100), the left side (L) of the panel, or the right side® of the panel.

[0208] In the case of (a) and (c) of FIG. 13, the display device (100) can configure and provide information on the expected location of the remote control device (200) based on the strength of the scan request signal or scan response signal or the signal reception direction. In this case, according to another embodiment, the display device (100) can configure and provide information on the location of the remote control device (200) using a ToF (Time of Flight) sensor or a lidar sensor. Alternatively, the remote control device (200) can provide its own location information (e.g., GPS information, etc.), and the display device (100) can compare the location information provided by the remote control device (200) with its own location information to provide information on the expected location of the remote control device (200).

[0209] FIG. 13(b) is similar to FIG. 13(a), in that the display device (100) can divide the peripheral area of ​​the display device and provide information on which area among the divided areas the remote control device (200) can be found. In this case, the display device (100) can also provide information on the probability of occurrence of the remote control device (200) (possibly in the form of text or digits) through color, color concentration or saturation in the case of the same color, etc., for the expected location of some of the divided areas.

[0210] In (d) of FIG. 13, information is provided in combination with or independently from (a) to (c) of FIG. 13, and provides information on the distance or signal intensity between the remote control device (200) and the display device (100) based on the aforementioned signal intensity, etc. For example, in (d) of FIG. 13, a signal level or distance level is displayed in two levels in the form of a bar graph, and when this is a signal level, the signal level is low, indicating that the distance between the two components is far, and when this is a distance level, the distance level is low, indicating that the distance between the two components is close.

[0211] FIGS. 11 and 12 are flowcharts illustrating a connection operation of a display device and a remote control device according to another embodiment of the present disclosure.

[0212] Referring to FIG. 11, the display device (100) can receive a packet from the remote control device (200) (S310).

[0213] The display device (100) can determine whether the parameter value of the packet received from the remote control device (200) is the first value (S320).

[0214] If, as a result of the S320 operation judgment, the parameter value of the packet received from the remote control device (200) is not the first value, the display device (100) can be paired with the remote control device (200) (S325). At this time, the first parameter value may be, for example, 0x03 of FIG. 9. Accordingly, the pairing may be the first pairing between the remote control device (200) and the display device (100).

[0215] If the parameter value of the packet received from the remote control device (200) is the first value as a result of the S320 operation judgment, the display device (100) can determine whether a preset condition is satisfied (S330).

[0216] If the display device (100) determines that a preset condition is not satisfied as a result of the S330 operation, i.e., if the remote control device search function is not activated, the display device (100) can ignore or filter the packet received from the remote control device (200) in the S310 operation (S335).

[0217] If the display device (100) determines that the S330 operation result satisfies a preset condition, it can transmit a scan signal to the remote control device (200) and connect (S340).
