The controller (280) can transmit a signal corresponding to a predetermined key operation of the user input interface (230) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor (240) to the display device (100) via the wireless communication unit (225).

[0112] Additionally, the microphone (290) of the remote control device (200) can acquire voice.

[0113] A plurality of microphones (290) may be provided.

[0114] Next, Figure 4 is described.

[0115] FIG. 4 shows an example of utilizing a remote control device according to an embodiment of the present disclosure.

[0116] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).

[0117] The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because, as shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space.

[0118] Figure 4 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left correspondingly.

[0119] 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.

[0120] Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.

[0121] Conversely, when the user moves the remote control device (200) closer to the display (180), the selection area within the display (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.

[0122] Meanwhile, when the remote control device (200) moves away from the display (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selection area may be zoomed in.

[0123] 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 (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).

[0124] 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).

[0125] Meanwhile, the pointer in this specification refers to an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, 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 (180), or may be displayed corresponding to multiple points such as lines or surfaces.

[0126] The display device (100) according to an embodiment of the present disclosure may be implemented in a movable form. That is, the display device (100) according to an embodiment of the present disclosure may be implemented as a portable display device that can be carried. For example, the display device (100) may further include a case that protects internal components and configurations including the display (180), and may be implemented so that images are played back when the case is open and can be moved when the case is closed.

[0127] Next, a movable display device (100) according to an embodiment of the present disclosure will be described with reference to FIGS. 5 to 7.

[0128] FIG. 5 is an exemplary drawing showing a closed state of a case of a display device according to an embodiment of the present disclosure, FIG. 6 is an exemplary drawing showing an open state of a case of a display device according to an embodiment of the present disclosure, and FIG. 7 is an exemplary drawing showing a display device and a remote control device according to an embodiment of the present disclosure.

[0129] As illustrated in the example of FIG. 5, the display device (100) according to an embodiment of the present disclosure may further include a case (310).

[0130] Various configurations of a display device (100) including a display (180) can be provided in the receiving space formed by the case (310) and inside the case (310).

[0131] The case (310) may include a main body (311) and a cover (313) covering the main body (311).

[0132] The accommodation space formed by the case (310) may refer to the space between the main body (311) and the cover (313). A display (180), remote control device (200), etc. may be placed in the accommodation space formed by the case (310).

[0133] The interior of the case (310) may refer to the interior of the main body (311) and the interior of the cover (313). That is, the interior of the case (310) may refer to the interior space of the main body (311) and the interior space of the cover (31) that are not visible to the user. A main mode (not shown) equipped with a controller (170), etc., may be accommodated inside the case (310).

[0134] Fig. 5 may show a closed state of the case (310). When the case (310) is closed, the display (180) and the like may not be visible from the outside.

[0135] Fig. 6 may show a case (310) in an open state.

[0136] The cover (313) can be connected to the main body (311) via a hinge (not shown) or the like.

[0137] The display (180) can be supported on the main body (311). The display (180) can be connected and fixed to the main body (311). The display (180) can be tilted at an angle while being supported on the main body (311). For example, the display (180) can be connected to the main body (311) via a hinge (not shown) or the like and can be tilted at various angles. The display (180) can be tilted at various angles based on a point connected to the main body (311). As illustrated in (a) of FIG. 6, the display (180) can be tilted to form 0 degrees with respect to the main body (311), and in this case, the display (180) can be completely accommodated in the accommodation space formed by the case (310). That is, when the display (180) is tilted to form 0 degrees with respect to the main body (311), the case (310) can be closed. Alternatively, as illustrated in (b) of FIG. 6, the display (180) may be tilted to form a right angle (90 degrees) with respect to the main body (311). Of course, the present invention is not limited to the example of FIG. 6, and the display (180) may be formed to be tilted within a range of 0 to 180 degrees with respect to the main body (311). In addition, the display (180) may be formed to be able to be tilted more than 180 degrees with respect to the main body (311).

[0138] And, when the display (180) forms a 0 degree angle with the main body (311), a storage space (S1) may be formed between the display (180) and the main body (311). The storage space (S1) may be a space in which a remote control device (200), a headset (not shown), etc. may be stored. Meanwhile, the name of the storage space is merely a name for convenience of explanation, and therefore, it is reasonable that the term is not limited thereto.

[0139] Figure 7 (a) shows a remote control device (200) accommodated in a storage space (S1), and Figure 7 (b) shows a remote control device (200) taken out from the storage space (S1) being used.

[0140] As illustrated in Fig. 7, the remote control device (200) can be accommodated in a storage space (S1). A user can open the case (310), tilt the display (180), and then take out the remote control device (200) accommodated in the storage space (S1).

[0141] The display device (100) described above is easy to move. However, when a user lifts the display device (100) to move it, the terminal or the cable connected to the terminal may be damaged.

[0142] In relation to this, it is explained with reference to Fig. 8.

[0143] FIG. 8 is a drawing for explaining a process of lifting a display device according to an embodiment of the present disclosure.

[0144] A handle (314) may be formed on a first surface of the case (310). The first surface may be a surface on which the case (310) opens.

[0145] At least one terminal (500) may be formed on the second side of the case (310). The first side may be a side on which a hinge (315) is arranged for opening and closing the case (310). The first side may be a side facing the second side.

[0146] A user can move the display device (100) by holding the handle (314). The user can lift the display device (100) by holding the handle (314). During this process, if a cable (510) is connected to at least one terminal (500), the cable (510) may bend before the second surface touches the floor. This may result in damage to the terminal (500) or the cable (510).

[0147] To prevent this, the present disclosure aims to output a cable removal notification when the movement status of the display device (100) is acquired, thereby allowing the user to remove the cable (510) connected to the terminal (500).

[0148] The display device (100) may be equipped with various terminals (500) to be connected to various external devices. In this regard, a detailed description will be given with reference to FIG. 9.

[0149] FIG. 9a is a drawing showing a closed state of a cover formed on a display device according to an embodiment of the present disclosure, and FIG. 9b is a drawing showing an open state of a cover formed on a display device according to an embodiment of the present disclosure.

[0150] Figures 9a and 9b are drawings showing the second side of the case (310).

[0151] The main body (311) may include at least one cover (400).

[0152] At least one terminal (500), an IR blaster (600), and a switch (700) may be arranged in the internal space of the case (310) covered by the cover (400). The cover (400) may protect the terminal (500), the IR blaster (600), and the switch (700) from the outside.

[0153] The main body (311) may include a first cover (410) and a second cover (420).

[0154] A first terminal (501), a second terminal (502), an IR blaster (600), and a switch (700) may be formed in the internal space of the main body (311) covered by the first cover (410).

[0155] The first terminal (501) and the second terminal (502) may be an HDMI terminal and a USB terminal, respectively.

[0156] An IR blaster (600) may be provided in the display device (100) to recognize the infrared signal of the remote control device (200).

[0157] The switch (700) may be a battery switch. The battery switch (700) may be a switch for controlling battery use. The display device (100) may receive power from the battery when the battery switch (700) is turned on. Accordingly, the display device (100) may be used wirelessly without being connected to a power source. The display device (100) may not receive power from the battery when the battery switch (700) is turned off. When the battery switch (700) is turned off, the remaining battery power is maintained even when the display device (100) is not used for a long period of time, thereby preventing battery discharge.

[0158] A third terminal (503) may be formed in the internal space of the main body (311) covered by the second cover (420). The third terminal (503) may be a power terminal. The display device (100) may be connected to a power supply device through the power terminal and may receive power from an external source. For example, the power supply device may be an AC power device.

[0159] A display device (100) according to an embodiment of the present disclosure can output a cable removal notification when it is determined that at least one terminal (500) and a cable (510) are connected in a moving situation.

[0160] At this time, the movement situation may include the actual movement situation and the movement preparation situation of the display device (100).

[0161] An actual moving situation may be a situation in which the display device (100) actually moves. The display device (100) may detect the movement of the display device (100) through a sensor (not shown). The sensor (not shown) may be an acceleration sensor. When the display device (100) detects the movement of the display device (100) while a cable (510) is connected to at least one terminal (500), the display device (100) may output a cable removal notification.

[0162] Movement of the display device (100) may include not only horizontal movement to a different location, but also vertical movement. For example, the movement situation of the display device (100) may include a situation in which the display device (100) is lifted.

[0163] The move preparation situation may be a situation in which preparations are made for moving the display device (100).

[0164] For example, the move preparation situation may include a situation in which a power-off input is obtained to turn off the power of the display device (100), a situation in which the case (310) is closed, a situation in which a move is recommended, a situation in which proximity control is initiated after remotely controlling the display device (100) for a preset number of times or a preset time, etc.

[0165] First, a situation in which the display device (100) obtains a power-off input will be described.

[0166] FIG. 10 is a flowchart illustrating a method for outputting a cable removal notification when a display device according to an embodiment of the present disclosure receives a power-off input.

[0167] The controller (170) can receive an input for selecting a cable removal notification (S110).

[0168] FIG. 11 is a drawing illustrating a screen displayed by a display device according to an embodiment of the present disclosure to select a cable removal notification.

[0169] Referring to FIG. 11, when the controller (170) enters a menu for changing the setting status of the display device (100), it may display a cable removal notification selection setting item (181). The cable removal notification may be a function to assist with the power shutdown mode. Accordingly, the cable removal notification setting item (181) may be displayed as 'power shutdown mode assistance.' The cable removal notification setting item (181) may include a 'yes' icon (182) and a 'no' icon (183).

[0170] The power shutdown mode may be a mode for selecting a function related to power shutdown when receiving a user input for power shutdown. For example, when entering the power shutdown mode, the controller (170) may display a power shutdown menu (330) as described later in FIG. 11. The power shutdown menu (330) may include items for providing functions related to power shutdown, such as 'power shutdown', 'restart', and 'cancel'.

[0171] An input that selects the 'Yes' icon (182) may be an input that selects the cable removal notification. An input that selects the 'No' icon (183) may be an input that does not select the cable removal notification.

[0172] When the controller (170) obtains an input for selecting the 'Yes' icon (182), and then obtains an input for turning off the power, it can enter the power off mode and output a cable removal notification.

[0173] Again, Figure 10 is explained.

[0174] The controller (170) can obtain an input to turn off the power of the display device (100) (S110).

[0175] There may be various input methods for turning off the power of the display device (100).

[0176] For example, the power-off input of the display device (100) may be an input of pressing the power button (231) of the remote control device (200). Alternatively, it may be an input of pressing the power button (not shown) provided in the display device (100), or an input of touching the power-off icon (not shown) through the display (180).

[0177] When the controller (170) receives an input to turn off the power, it can output a first notification (S130).

[0178] The controller (170) can output a cable removal notification through the display (180). The cable removal notification output by the controller (170) through the display (180) may be a first notification. Meanwhile, as described below, the controller (170) can output a cable removal notification through the speaker (185). The cable removal notification output by the controller (170) through the speaker (185) may be a second notification.

[0179] The controller (170) may enter a power-off mode when receiving an input to turn off the power. The controller (170) may enter the power-off mode and output a cable removal notification.

[0180] Referring to FIGS. 12 and 13, a method for a display device to output a cable removal notification according to an embodiment of the present disclosure is described.

[0181] FIG. 12 is a drawing illustrating a display device according to an embodiment of the present disclosure outputting a cable removal notification.

[0182] Additionally, FIG. 12 may be a screen displayed when the controller (170) enters power off mode.

[0183] When the controller (170) enters the power off mode, it can display a power off menu (330). The power off menu (330) can include items for providing functions related to power off, such as ‘power off,’ ‘restart,’ and ‘cancel.’

[0184] When the controller (170) enters power-off mode, it may display a cable removal notification (340). The cable removal notification (340) may include a message (341) requesting cable removal and a terminal list (342). The terminal list (342) may include at least one item corresponding to at least one terminal.

[0185] The message (341) for requesting cable removal may be 'You can turn off the device after checking the currently connected external connection terminal.', but this is only an example.

[0186] The terminal list (342) may include at least one terminal icon (520) corresponding to at least one terminal (500) and at least one name of the terminal (500).

[0187] At least one terminal icon (520) may include first to third terminal icons (521, 522, 523). The first to third terminal icons (521, 522, 523) may correspond to an HDMI terminal (501), a USB terminal (502), and a power terminal (503), respectively, but this is merely an example.

[0188] The controller (170) can display at least one terminal icon (500) based on the position at which each of the at least one terminals (500) is arranged.

[0189] For example, when viewed from the front of the second surface where the terminal (500) of the case (310) is formed, an HDMI terminal (501), a USB terminal (502), and a power terminal (503) may be formed sequentially from the left.

[0190] Accordingly, the controller (170) can sequentially display an icon (521) corresponding to an HDMI terminal, an icon (522) corresponding to a USB terminal, and an icon (523) corresponding to a power terminal on the display (180) from the left side of the display (180).

[0191] That is, the controller (170) can display terminal icons (500) in the same order as the order in which the terminals (500) are formed when the case (310) is viewed from the front of the second surface.

[0192] Meanwhile, the controller (170) may display an indicator (530) on a terminal icon (500) corresponding to a terminal connected to a cable. The indicator (530) may be displayed to distinguish a terminal icon corresponding to a terminal connected to a cable from a terminal icon corresponding to a terminal not connected to a cable.

[0193] According to an embodiment, the indicator (530) may be displayed in the form of an icon that changes the color of an icon corresponding to a terminal that is connected to a cable. For example, when a cable is connected to a USB terminal (502), the controller (170) may display the terminal icon (522) corresponding to the USB terminal by changing it to red, and display the icons (521, 523) corresponding to the remaining terminals in black and white.

[0194] Accordingly, the user can intuitively know which terminal (500) the cable must be removed from.

[0195] FIG. 13 is a drawing illustrating a display device according to another embodiment of the present disclosure outputting a cable removal notification.

[0196] The controller (170) can display at least one terminal icon (500) based on the position at which each of the at least one terminals (500) is arranged.

[0197] For example, when viewed from the front of the second surface where the terminal (500) of the case (310) is formed, an HDMI terminal (501), a USB terminal (502), and a power terminal (503) may be formed sequentially from the left.

[0198] At this time, when the display (180) is set up as shown in FIG. 6, when viewed from the front of the first side of the case (310), a power terminal (503), a USB terminal (502), and an HDMI terminal (501) may be formed sequentially from the left.

[0199] Accordingly, the controller (170) can sequentially display an icon (523) corresponding to the power terminal, an icon (522) corresponding to the USB terminal, and an icon (521) corresponding to the HDMI terminal on the display (180) from the left side of the display (180).

[0200] That is, the controller (170) can display the terminal icons (500) in the reverse order of the order in which the terminals (500) are formed when the case (310) is viewed from the front of the second side.

[0201] Additionally, the controller (170) can display a terminal icon (520) in an area of ​​the display (180) that corresponds to the actual location of the terminal (500). For example, the area where an icon (521) corresponding to an HDMI terminal is displayed may be an area corresponding to the location where the HDMI terminal (501) is placed in the case (310).

[0202] Accordingly, the user can remove the cable based on the position where the terminal icon (520) is displayed without having to rotate the display device (100) to check the position of the terminal (500) from which the cable of the display device (100) is to be removed.

[0203] Depending on the embodiment, the controller (170) may display only icons corresponding to the terminals to which the cables are connected. For example, if a cable is connected only to a USB terminal (502), the controller (170) may display only the terminal icon (522) corresponding to the USB terminal. Accordingly, the user can recognize the terminal to which the cable is connected and remove the cable connected to the corresponding terminal.

[0204] Again, Figure 10 is explained.

[0205] When the controller (170) determines that the case (310) is closed (S140), it can output a second notification (S150).

[0206] When the case (310) is closed, the user cannot confirm the first notification displayed on the display (180). Therefore, the controller (170) can audibly output a cable removal notification through the speaker (185).

[0207] The cable removal notification output through the speaker (185) may be a notification that outputs a message included in the cable removal notification output through the display (180) as a voice. Alternatively, the cable removal notification output through the speaker (185) may be output as a notification sound.

[0208] The controller (170) can output a cable removal notification to the first volume after a preset time has elapsed after the case (310) is closed.

[0209] The preset waiting time may be longer than the waiting time when the case (310) is not closed. For example, the waiting time when the case (310) is not closed may be 1 minute, and the preset waiting time may be 2 minutes.

[0210] The preset time may be a time set to be longer than the standby time when the case (310) is not closed, taking into account the case where a user who has not removed the cable resumes using the display device (100).

[0211] Next, the controller (170) can output a cable removal notification to the second volume when it detects movement of the display device (100).

[0212] In situations where the display device (100) is actually moving, it is necessary to clearly inform the user that the cable needs to be removed.

[0213] Accordingly, when the controller (170) detects movement of the display device (100), it can output a cable removal notification in a second volume that is larger than the first volume.

[0214] To summarize FIGS. 10 to 13, when a display device (100) according to an embodiment of the present disclosure obtains a power-off input, it can display at least one terminal icon (520) corresponding to each of at least one terminal (500), and display an indicator (530) for a terminal icon corresponding to a terminal connected to a cable among at least one terminal icon (520).

[0215] Accordingly, the user can recognize that there is a terminal (500) to which a cable is connected and intuitively check which terminal (500) the cable (510) is connected to. Accordingly, the user can easily remove the cable (510) connected to the terminal (500), thereby preventing damage to the terminal (500) or the cable (510).

[0216] Meanwhile, the display device (100) according to the embodiment of the present disclosure can output a cable removal notification considering the remaining battery level and output a message recommending turning off the battery switch (700). In this regard, a description will be given with reference to FIGS. 14 and 15.

[0217] FIG. 14 is a flowchart illustrating a method for a display device according to an embodiment of the present disclosure to output a cable removal notification by taking into account the remaining battery capacity.

[0218] FIG. 14 may be a flowchart specifically explaining another embodiment of step S130 of FIG. 10.

[0219] The controller (170) can obtain the remaining battery capacity when the power cable is connected to the power terminal (503) in a moving situation (S210).

[0220] The controller (170) can output a cable removal notification (S230) when the remaining battery level exceeds a preset first reference remaining level (S220).

[0221] The preset first reference remaining amount may be a remaining amount set to be sufficient to use the display device (100) for a predetermined period of time or longer. For example, the preset first reference remaining amount may be 85%.

[0222] After the controller (170) outputs a cable removal notification, it can be determined that the cable connected to the power terminal (503) has been removed (S240).

[0223] The controller (170) can re-acquire the remaining battery capacity when it determines that the cable connected to the power terminal (503) has been removed (S250). If the remaining battery capacity is lower than a preset second reference remaining capacity (S260), the controller (170) can recommend turning off the battery switch (S270).

[0224] Referring to FIG. 15, an operation of a display device according to an embodiment of the present disclosure to output a message recommending turning off a battery switch is described.

[0225] FIG. 15 is a drawing illustrating a display device according to an embodiment of the present disclosure recommending that the battery switch be turned off.

[0226] The controller (170) can display a message (351) recommending turning off the battery switch and an icon (720) corresponding to the battery switch when the remaining battery level is less than a preset second reference remaining level.

[0227] A message recommending turning off the battery switch (351) may be "Your current battery level is 15%. Please turn off the battery switch before turning off the device." This is only an example.

[0228] The controller (170) can display an icon (720) and indicator corresponding to the battery switch. For example, the controller (170) can display an icon (720) corresponding to the battery switch so that it flashes red.

[0229] The controller (170) may display only an icon (720) corresponding to the battery switch as shown in FIG. 14, but may also display an icon (520) corresponding to the terminal, depending on the embodiment.

[0230] The preset second reference remaining amount may be set to a remaining amount at which the display device (100) is at risk of discharge if the display device (100) is not used or charged for a predetermined period of time. For example, the preset second reference remaining amount may be 25%.

[0231] To summarize FIGS. 14 and 15, the display device (100) according to an embodiment of the present disclosure may output a cable removal notification for the power cable when the remaining battery level exceeds a preset first reference remaining level when a power cable is connected to the power terminal (503). In addition, the display device (100) according to an embodiment of the present disclosure may output a message recommending turning off the battery switch (700) when the power cable is removed and the remaining battery level is below a preset second reference remaining level.

[0232] Accordingly, the display device (100) according to the embodiment of the present disclosure can prevent damage to the cable (510) or terminal (500) while minimizing battery power in a standby state.

[0233] Meanwhile, depending on the embodiment, the movement preparation situation may include a situation in which input is obtained through a remote control device (200) for a preset number of times or a preset time or more and then input is obtained through a display device (100).

[0234] The display device (100) can be remotely controlled via a remote control device (200). Remote control can be performed in a situation where the user is at a predetermined distance from the display device (100) to view content of the display device (100).

[0235] Additionally, the display device (100) can be proximity controlled via a physical button or touch input via the display (180). Proximity control can be performed when a user approaches the display device (100) to end use of the display device (100) and move to another location.

[0236] Accordingly, the controller (170) can output a cable removal notification in a situation where the display device (100) is controlled remotely for a preset number of times or for a preset time or more and proximity control is initiated.

[0237] The preset number of times and preset time can be determined by considering the usage time of the user's display device (100), the length of the content, etc.

[0238] According to an embodiment, the display device (100) may output a notification when the cover (400) is opened. This is because when the cover (400) is moved while open, the terminals (500) formed inside the space covered by the cover (400) may be exposed to the outside and damaged.

[0239] Depending on the embodiment, the move preparation situation may include a situation in which the case (310) is closed.

[0240] In relation to this, it is explained with reference to Fig. 16.

[0241] FIG. 16 is a drawing illustrating a display device according to an embodiment of the present disclosure.

[0242] The case (310) may include a fastening portion (312). The fastening portion (312) may be provided on the main body (311) to secure the case (310) in a closed state. The fastening portion (312) may be secured to a fastening groove (not shown) formed in the cover (313) after the case (310) is closed, thereby securing the case (310) in a closed state. The controller (170) may obtain whether the fastening portion (312) is fastened through a Hall sensor (not shown) placed in the fastening portion (312) or the fastening groove (not shown).

[0243] The controller (170) can determine that the case (310) is closed when the fastening part (312) is fastened and output a cable removal notification.

[0244] According to an embodiment, the controller (170) may obtain that the case (310) is closed through a hall sensor (not shown) disposed in at least one of the main body (311) and the cover (313), and output a cable removal notification.

[0245] According to an embodiment, the movement preparation situation may include a situation in which the display device (100) recommends movement. In this regard, this will be described with reference to FIG. 17.

[0246] FIG. 17 is a drawing illustrating a display device according to an embodiment of the present disclosure recommending movement.

[0247] The controller (170) can recommend movement based on weather information received from an external source (not shown).

[0248] The movable display device (100) is highly mobile and can be used outdoors, so it can recommend movement based on weather information. For example, if the controller (170) obtains weather information indicating a storm is expected in 15 minutes, it can display a message (341) recommending movement.

[0249] A message recommending a move might be 'Storm expected in 15 minutes, remove external devices and prepare to move', but this is just an example.

[0250] The controller (170) can display a weather information icon (343). The weather information icon (343) may be an icon for intuitively informing weather information.
