[0191] In embodiments of the present invention, the 'vehicle rear seat display device' is a display device placed on the rear seat of a vehicle (100), and may be formed to be movable in different directions. The vehicle rear seat display device may be equipped with a plurality of drive modules for moving in different directions. In addition, the vehicle rear seat display device may be formed to be tiltable to have a predetermined angle with respect to the ceiling of the vehicle.

[0192] FIG. 2 is a drawing showing a vehicle rear seat display device (800) according to an embodiment of the present invention installed in a vehicle (100).

[0193] As illustrated in FIG. 2, a vehicle rear seat display device (800) may be formed such that a plurality of movable frames (840a, 840b) are connected to a fixed frame (801) installed on the ceiling facing the rear seat from the front seat (110) in the vehicle (100), and first and second displays (820a, 820) are arranged on the front of the plurality of movable frames (840a, 840b), respectively.

[0194] Meanwhile, an angle adjusting unit (860) may be mounted on the back surface of the plurality of movable frames (840) to adjust the angle of the first and second displays (820a, 820b). Depending on the operation of the angle adjusting unit (860), the first and second displays (820a, 820) may be horizontal to the fixed frame (801) or may be vertical as shown.

[0195] A plurality of movable frames (840) are formed to be movable in different directions. Accordingly, the first and second displays (820a, 820b) arranged on the front of each of the plurality of movable frames (840) can move in different directions.

[0196] Specifically, the plurality of movable frames (840) can move forward of the front seats or backward of the front seats (or forward of the rear seats) along the longitudinal direction of the fixed frame (801) installed on the ceiling. Accordingly, the first and second displays (820a, 820b) move forward of the front seats of the vehicle (100) or forward of the rear seats.

[0197] Additionally, the plurality of moving frames (840) can be moved closer to or further away from each other. Accordingly, the spacing between the first and second displays (820a, 820b) is adjusted so that they come closer to (or come into contact with) or further away from each other.

[0198] When the first and second displays (820a, 820b) are positioned in front of the front seats of the vehicle (100) as the plurality of moving frames (840) move to the front of the front seats, the passengers in the front seats (driver and / or passenger in the front seat) can receive content services through the first and second displays (820a, 820b).

[0199] Meanwhile, when a plurality of moving frames (840) are positioned behind the front seats as illustrated in FIG. 2, passengers in the rear seats of the vehicle (100) can receive content services through the first and second displays (820a, 820b).

[0200] In addition, when the first and second displays (820a, 820b) are spaced apart from each other, passengers in the rear seat of the vehicle (100) can receive content services through the first and second displays (820a, 820b) as independent screens. That is, the passenger in the left rear seat can receive content services through the first display (820a), and the passenger in the right rear seat can receive another content service through the second display (820b).

[0201] Meanwhile, if the spacing between the first and second displays (820a, 820b) is adjusted to become closer, the entire first and second displays (820a, 820b) can operate in full screen mode. That is, if the first and second displays (820a, 820b) become close to each other and come into contact, they can be switched to full screen mode without additional screen control.

[0202] In another embodiment, if it is determined that there is no intention to use the first and second displays (820a, 820b), folding may be performed so that the plurality of movable frames (840) form a horizontal line with respect to the fixed frame (801) according to the operation of the angle adjustment unit (860).

[0203] The state in which the plurality of movable frames (840) illustrated in FIG. 2 form a vertical line with the fixed frame (801) is defined as an "unfolding state." In addition, although not illustrated, the state in which the plurality of movable frames (840) form a horizontal line with the fixed frame (801) is defined as a "folding state."

[0204] Referring to FIG. 2, a portion of a plurality of movable frames (840) connected to a fixed frame (801) remains fixed, and the plurality of movable frames (840) can be rotated significantly toward the fixed frame (801) as if bending until they form a horizontal line with the fixed frame (801), thereby transitioning from an “unfolding state” to an “unfolding state.”

[0205] In this way, the vehicle rear seat display device (800) according to an embodiment of the present invention is movable between the front and rear seats, and multiple displays are movable to move closer or further away from each other, so that all passengers in the vehicle (100) can receive content services through the rear seat display device (800).

[0206] FIG. 3 is a block diagram for explaining the detailed configuration of a vehicle rear seat display device (800) according to an embodiment of the present invention.

[0207] A vehicle rear seat display device (800) may include a communication unit (810), first and second displays (820a, 820b), first and second driving modules (830a, 830b), a plurality of moving frames (840), a control unit (850), an angle adjustment unit (860), and an input unit (870). In addition, the vehicle rear seat display device (800) may be connected to a system within a vehicle (100) so as to be communicable therewith through the communication unit (810).

[0208] The communication unit (810) can receive vehicle data and vehicle driving data by communicating with the vehicle (100), the system within the vehicle (100), various sensors within the vehicle (100), and various devices such as ADAS (Advanced Driver Assistance Systems) and DMS (Driver Monitoring System).

[0209] In addition, the communication unit (810) can receive an input signal corresponding to an input applied to an input device installed in the vehicle (100) and transmit it to the control unit (850). For example, the communication unit (810) can receive a signal related to the driving of at least one of the first and second driving modules (830a, 830b) of the rear seat display device (800) from an input device linked in the vehicle (100).

[0210] The display of the rear seat vehicle display device (800) is configured to include first and second displays (820a, 820b), each having a separate frame. The first and second displays (820a, 820b) may each display different screens, the same screen, or a single connected screen.

[0211] The first and second displays (820a, 820b) may be arranged on the front surfaces of a plurality of movable frames (840) arranged side by side. In other words, the first and second displays (820a, 820b) may be arranged to be coupled to movable frames formed to be movable on the back surfaces of each of the first and second displays (820a, 820b). Accordingly, as the plurality of movable frames (840) move, the coupled first and second displays (820a, 820b) may also move together.

[0212] When the first and second displays (820a, 820b) are used as independent screens, each screen can be controlled independently. Furthermore, when the first and second displays (820a, 820b) are used as full screens, a single, integrated screen control can be performed.

[0213] In an embodiment, the screen control of the first and second displays (820a, 820b) may be performed based on the movement according to the driving of the first and second driving modules (830a, 830b). For example, if the first and second displays (820a, 820b) move toward the front or rear seats according to the driving of the first driving module (830a), the type of displayed content may change. In addition, for example, if the first and second displays (820a, 820b) move closer or farther away from each other according to the driving of the second driving module (830b), the screen mode (e.g., full screen mode) of the displays may change.

[0214] The first and second driving modules (830a, 830b) provide driving force to move the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in a first direction or a second direction. Specifically, the first driving module (830a) can transmit driving force to the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in the first direction, that is, in a direction toward the front seat or toward the rear seat together. In addition, the second driving module (830b) can provide driving force to the plurality of moving frames (840) so that the first and second displays (820a, 820b) move in the second direction, that is, in a direction toward or away from each other.

[0215] First and second displays (820a, 820b) are respectively arranged on the front of the plurality of movable frames (840). One side of the plurality of movable frames (840) is connected so as to be in contact with one side of a fixed frame (801, FIG. 2) connecting the front and rear seats of the vehicle ceiling. Accordingly, when the first driving module (830a) is driven, the plurality of movable frames (840) can be operated to move along the longitudinal direction of the fixed frame (801).

[0216] A plurality of moving frames (840) may be arranged side by side with a predetermined spacing distance between them, and may be formed to be supported by an identical support frame located on the rear surface. Accordingly, when the second driving module (830b) is driven, the plurality of moving frames (840) may move closer to each other or move again to have a predetermined spacing distance while being supported by the identical support frame.

[0217] The control unit (850) controls the overall operation of the vehicle rear seat display device (800). The control unit (850) may be referred to as a processor or a PC, and may be placed, for example, within a housing located between the front seats inside the vehicle (100).

[0218] The control unit (850) can control the driving of the first and second driving modules (830a, 830b) and the screens of the first and second displays (820a, 820b). In an embodiment, the control unit (850) can control the first driving module (830a) so that the first and second displays (820a, 820b) move together in a first direction in response to a first input signal. In addition, the control unit (850) can control the second driving module (830b) so that the first and second displays (820a, 820b) move in a second direction different from the first direction to move away from or toward each other in response to a second input signal different from the first input signal.

[0219] The angle adjustment unit (860) can be placed between a fixed frame located on the back of a plurality of moving frames (840) and a fixed frame (801, FIG. 2) formed on the ceiling of the vehicle.

[0220] The angle adjustment unit (860) is coupled to one side of a plurality of movable frames (840) and can operate to allow the plurality of movable frames (840) to form a predetermined angle with respect to the fixed frame (801). Specifically, the angle adjustment unit (860) provides a driving force for the plurality of movable frames (840) to rotate so that the plurality of movable frames (840) form a horizontal plane, a vertical plane, or a set angle between the horizontal and vertical planes with respect to the fixed frame (801).

[0221] The input unit (870) may be placed on one side of the vehicle (100) so as to be spaced apart from the first and second displays (820a, 820b). The input unit (870) may be configured to include a plurality of buttons corresponding to each direction or an operation unit that can be tilted / moved in a plurality of directions in order to control the movement direction of the first and second displays (820a, 820b).

[0222] In an embodiment, when a first input signal is generated based on a first input to the input unit (870), the control unit (850) can drive the first drive module (830a) to control the first and second displays (820a, 820b) to move together in a first direction. In addition, when a second input signal is generated based on a second input to the input unit (870), the control unit (850) can drive the second drive module (830b) to control the first and second displays (820a, 820b) to move in a second direction toward or away from each other.

[0223] FIG. 4 is a conceptual diagram for explaining the movement operation of a vehicle rear seat display device (800) and compatibility with a front seat display device according to an embodiment of the present invention.

[0224] The vehicle rear seat display device (800) can be used by a rear seat passenger, or can be moved toward the front seat and operated for use by a front seat passenger.

[0225] To this end, the vehicle rear seat display device (800) can communicate with other display devices located in the front seat via a router. In addition, the vehicle rear seat display device (800) can determine whether to move the vehicle rear seat display device (800) based on the results of communication with the other display devices.

[0226] Specifically, when an input is received through an input unit (870) of a rear-seat display device (800), such as a hard key or a touch screen, the first processor (850a) can transmit a signal corresponding to the received input to the second processor (850b) via a router. At this time, the first processor (850a) may be, for example, NVIDIA SYSTEM, and the second processor (850b) may be, for example, a mini PC.

[0227] As another example, the first processor (850a) can directly transmit a signal corresponding to the received input to the first drive module (830a) as a drive signal for moving the first and second displays (820a, 820b) in the forward / backward direction. Accordingly, the motor of the first drive module (830a) is driven, and a driving force is generated for moving the first and second displays (820a, 820) in the forward / backward direction.

[0228] Meanwhile, the functions of the first and second processors (850a, 850b) illustrated in FIG. 4 may be implemented by being swapped, performing some operations separately, or being performed by one processor (850).

[0229] In addition, an input of a request identical to the input to the input unit (870) may be made through the display or the operating unit of the front seat of the vehicle (100). In this case, similarly to the above-described case, a signal corresponding to the input is transmitted to the processor of the rear seat display device (800) of the vehicle through the router, thereby operating the motor of the first drive module (830a) so that the first and second displays (820a, 820b) move back and forth.

[0230] Additionally, the vehicle rear seat display device (800) can be used as multiple independent screens for each rear seat passenger to use, or as a full screen in which multiple screens are moved closer to each other to display a single connected image.

[0231] To this end, the vehicle rear seat display device (800) can drive the motor of the second drive module (830b) to move the first and second displays (820a, 820b) closer to or further away from each other based on a signal corresponding to another input applied to the input unit (870) as illustrated in FIG. 4 being transmitted to the first and / or second processors (850a, 850b) (or processor (850)).

[0232] At this time, each of the moving frames (840, Fig. 2) on which the first and second displays (820a, 820b) are arranged moves toward or away from each other, and therefore each has a separate driving motor. In addition, the motors matching each moving frame (840) rotate in opposite directions, thereby causing the plurality of moving frames (840) to gradually approach or move away from each other.

[0233] In addition, in the embodiment, the vehicle rear seat display device (800) can adjust the angle adjustment unit (860) so that the first and second displays (820a, 820b) can form a predetermined angle with respect to the fixed frame (801, FIG. 2) arranged on the ceiling of the vehicle (100). The angle adjustment unit (860) can operate to tilt the first and second displays (820a, 820b) by driving a motor so that the plurality of movable frames (840) form an angle with the fixed frame (801) that is horizontal, vertical, or in a range therebetween.

[0234] For example, when the first and second displays (820a, 820b) of the vehicle rear seat display device (800) are moved to the front of the vehicle, the information is transmitted to the front seat display and the system through the router, and the angle adjustment unit (860) can operate so that the plurality of moving frames (840) form a predetermined angle between the horizontal and vertical with the fixed frame (801).

[0235] In addition, for example, before the first and second displays (820a, 820b) of the vehicle rear seat display device (800) move to the front of the front seat or the front of the rear seat of the vehicle, the angle adjustment unit (860) may operate so that the plurality of moving frames (840) form a horizontal line with the fixed frame (801).

[0236] Meanwhile, although not shown in detail, when the front seat display is in operation while the vehicle is in a driving state, the processor (850) can limit the operation of the first drive module (830a) so that the first and second displays (820a, 820b) of the vehicle rear seat display device (800) do not move toward the front of the vehicle's front seat. Accordingly, driving safety is prevented from being hindered.

[0237] Similarly, when the front seat display is in operation during manual driving of the vehicle, the processor (850) may limit the operation of the second driving module (830b) so that the first and second displays (820a, 820b) of the rear seat display device (800) of the vehicle do not move in a direction that brings them closer to each other. Accordingly, the first and second displays (820a, 820b) are prevented from blocking the rearview mirror during manual driving of the driver.

[0238] As described above, the vehicle rear seat display device (800) according to an embodiment of the present invention provides expanded usability by operating the first and second displays (820a, 820b) in different directions or forming a predetermined angle in conjunction with the vehicle's front seat display. In addition, by limiting the movement of the first and second displays (820a, 820b) according to the operation of the front seat display according to the vehicle's driving status, a service can be provided while taking vehicle driving safety into consideration.

[0239] Below, FIGS. 5a, 5b, 5c, and 5d are conceptual diagrams for explaining how the vehicle rear seat display device (800) moves in different directions and is angle-adjusted.

[0240] The vehicle rear seat display device (800) can be used as an integrated full screen or as multiple independent screens by moving in a direction closer or farther away from each other at a position corresponding to the rear seat of the vehicle.

[0241] In addition, the vehicle rear seat display device (800) provides expanded usability by allowing not only rear seat passengers but also front seat passengers to use multiple screens by moving to a position corresponding to the front seat of the vehicle or moving back to a position corresponding to the rear seat.

[0242] Furthermore, when the vehicle rear seat display device (800) is not used and is used by passengers in the front seats of the vehicle, it operates so that multiple screens form a set angle, thereby efficiently using the vehicle space and providing comfortable viewing and viewing to passengers in the front seats.

[0243] Figure 5a is an exemplary drawing showing the initial state of a vehicle rear seat display device (800).

[0244] In the initial state of the vehicle rear seat display device (800), the first and second displays (820a, 820b) are positioned at the rear of the front seat of the vehicle (or in front of the rear seat), and one side is coupled to a fixed frame (801, FIG. 2) of the ceiling to maintain a horizontal state. Accordingly, as shown in (a) of FIG. 5A, the plurality of movable frames (840a, 840b) face the ceiling of the vehicle, and as shown in (b) of FIG. 5A, the fronts of the first and second displays (820a, 820b) face the floor of the vehicle.

[0245] FIG. 5b is an exemplary drawing showing a state in which each passenger in the rear seat is using the vehicle rear seat display device (800). That is, this is an example in which the first and second displays (820a, 820b) of the vehicle rear seat display device (800) are used as multiple independent screens in the rear seat.

[0246] The first and second displays (820a, 820b) are kept apart from each other by a predetermined distance (L1) and are kept vertical with respect to the fixed frame (801, Fig. 5a) of the ceiling (a).

[0247] In this case, the first display (820a) is displayed for the passenger on the left side of the rear seat, and the second display (820b) is displayed for the passenger on the right side of the rear seat. Furthermore, only one of the first and second displays (820a, 820b) may be activated, while the other may remain inactive. Furthermore, the first and second displays (820a, 820b) may each be used as multiple independent screens, and may simultaneously display the same content screen. Furthermore, in an embodiment, the screen displayed on one of the first and second displays (820a, 820b) may be transmitted to the other.

[0248] Also, in FIG. 5b, a plurality of movable frames (840a, 840b) are positioned on the backs of the first and second displays (820a, 820b) and face the front seats of the vehicle (100) (b). Also, an angle adjusting unit (860) coupled to a portion of the plurality of movable frames (840a, 840b) and a portion of the fixed frame (801) supports the plurality of movable frames (840a, 840b) to maintain a horizontal state with respect to the fixed frame (801).

[0249] FIG. 5c is an exemplary drawing showing a state in which multiple screens of a rear seat display device (800) move closer to each other and operate in full screen.

[0250] Each of the plurality of moving frames (840a, 840b) has a motor, and the linked motors rotate in different directions (a) based on a control signal of the processor (850) so that the first and second displays (820a, 820b) move in a direction (L2) toward each other. When one side of the first and second displays (820a, 820b) contacts each other, the operation of each linked motor is stopped. The processor (850) can control the screen so that the first and second displays (820a, 820b) display one image in full screen or display execution screens of the same application on multiple screens.

[0251] While a plurality of moving frames (840a, 840b) move toward each other in a direction closer to each other according to the operation of the second driving module (830b) located on the rear surface, the fixed frame (801) on the ceiling, the angle adjustment unit (860) connected thereto, and the fixed frame on the rear surface included in the second driving module (830b) are formed to support the plurality of moving frames (840a, 840b) (b).

[0252] Meanwhile, the movement of the first and second displays (820a, 820b) to become closer to each other as shown in FIG. 5c may be performed before the first and second displays (820a, 820b) move toward the front of the vehicle's front seats. In other words, while the plurality of moving frames (840) move forward / backward along the longitudinal direction of the fixed frame (801) of the ceiling, the first and second displays (820a, 820b) move together while maintaining contact with each other.

[0253] Next, FIG. 5d is an exemplary drawing showing a state in which multiple screens of the rear seat display device (800) move toward the front seats and operate so that they are available to passengers in the front seats.

[0254] Referring to FIG. 5d, the first and second displays (820a, 820b) move toward the front seat (110) along the longitudinal direction (L3) of the fixed frame of the vehicle ceiling according to the driving of the first driving module (830a). At this time, the front of the first and second displays (820a, 820b) faces the floor, and the plurality of moving frames are tilted toward the ceiling and move in a folded state facing the fixed frame (801) of the ceiling (a).

[0255] When the movement is completed by reaching the end of the longitudinal direction (L3) of the fixed frame (801), the first and second displays (820a, 820b) are unfolded at an angle that can be viewed by the passengers in the front seats (110) and operate to form a predetermined angle with the fixed frame (801) of the ceiling (d).

[0256] Meanwhile, although not illustrated, a similar movement operation as described above may be performed when the first and second displays (820a, 820b) move from the front seat (110) toward the rear seat. Specifically, the first and second displays (820a, 820b) tilted for the occupants of the front seat (110) are folded to form a horizontal line again with the fixed frame (801) of the ceiling, and then move toward the rear seat along the longitudinal direction (L3) of the fixed frame (801). When the movement is completed by reaching the end of the longitudinal direction (L3) of the fixed frame (801), the initial state described with reference to FIG. 5a may be maintained, or the display may be unfolded to form a vertical line with the fixed frame (801) of the ceiling so that the occupants of the rear seat can use the display.

[0257] FIG. 6 is a representative flowchart for explaining an operation method of a vehicle rear seat display device (800) according to an embodiment of the present invention. Each operation illustrated in FIG. 6 may be performed by a control unit (850) (or a processor (850)) unless otherwise described. In addition, in some embodiments, when the vehicle rear seat display device (800) is included as part of a vehicle system, it may be performed by a control unit / processor of the vehicle system.

[0258] The rear seat display device (800) can be initially positioned at the rear of the front seat backrest of the vehicle. The rear seat display device (800) includes a first display (820a) and a second display (820b) arranged on the front of each of a plurality of movable frames (840) arranged side by side. At this time, one side of the plurality of movable frames (840) is coupled to one side of a fixed frame (801, FIG. 2) of the ceiling of the vehicle (100), so that the first and second displays (820a, 820b) located at the front can be supported by the fixed frame (801) when in use and when moving.

[0259] In the initial state, the first and second displays (820a, 820b) can be kept in a folded state so as to form a horizontal line with the fixed frame (801) of the ceiling in an inactive state. Thereafter, when a passenger in the rear seat of the vehicle (100) requests use of at least one of the first and second displays (820a, 820b), the first and second displays (820a, 820b) can be unfolded so as to form a vertical line with respect to the fixed frame (801).

[0260] In some embodiments, when the presence of a rear seat passenger of the vehicle is detected, it is determined that there is a request for use of at least one of the first and second displays (820a, 820b), and the first and second displays (820a, 820b) may be unfolded to form a vertical position with respect to the fixed frame (801).

[0261] The angle adjustment unit (860) of the vehicle rear seat display device (800) provides a driving force for an unfolding operation to the plurality of movable frames (840) so that the plurality of movable frames (840) form a vertical position with the fixed frame (801) of the ceiling in the aforementioned initial state. Accordingly, according to the unfolding operation of the plurality of movable frames (840), the first and second displays (820a, 820b) arranged at the front are unfolded so that the plurality of screens face the rear seat passengers.

[0262] The control unit (850) of the vehicle rear seat display device (800) controls the screen to display screen information on at least one of the first and second displays (820a, 820b) at a location corresponding to the rear seat of the vehicle (S10).

[0263] Once the unfolding of the first and second displays (820a, 820b) is completed, at least one of the first and second displays (820a, 820b) is switched from an inactive state to an active state. In some embodiments, the vehicle rear seat display device (800) may be activated through an interaction, such as touching the screen of the first and second displays (820a, 820b).

[0264] Next, the vehicle rear seat display device (800) controls the first drive module (830a) to move the first and second displays (820a, 820b) together in the first direction in response to the first input signal (S20).

[0265] Here, the first input signal may include a control signal for moving the first and second displays (820a, 820b) together from one of the front and rear seats to the other, or may be a signal that triggers the generation of such a control signal. This first input signal may be generated by touching a specific button forming the input unit (870) or by a preset operation input.

[0266] In addition, the first direction here refers to the longitudinal direction of the fixed frame (801) of the ceiling connecting the front and rear seats of the vehicle. Specifically, the first direction includes both the direction in which the plurality of movable frames (840) move from the rear seat to the front seat according to the driving of the first driving module (830a) and the direction in which the plurality of movable frames (840) move from the front seat to the rear seat according to the driving of the first driving module (830a).

[0267] The first driving unit (830a) is arranged to be movable together with a plurality of moving frames (840) along a guide rail (not shown) arranged on the first fixed frame (801) of the ceiling. In addition, the first driving unit (830a) may be equipped with a driving motor for providing driving force to the plurality of moving frames (840) for movement in the first direction.

[0268] Meanwhile, in another embodiment, the operation of the first drive module (830a) corresponding to the first input signal may be limited depending on the driving state of the vehicle. Specifically, the communication unit (810) of the vehicle rear seat display device (800) receives information on the state and driving state of the vehicle from the vehicle (100) and transmits the information to the control unit (850). Then, the control unit (850) determines whether to move the first and second displays (820a, 820b) together in the first direction based on the received information.

[0269] For example, if the vehicle (100) is driving at the time when the first input signal is received, the control unit (850) can limit the operation of the first driving module (830a) so that the first and second displays (820a, 820b) do not move in the first direction toward the front seats. That is, the first driving module (830a) can be operated so that the first and second displays (820a, 820b) move in the first direction toward the front seats only when the vehicle (100) is stopped. Accordingly, the plurality of screens operate so as not to move toward the front seats while the vehicle is driving and thus not to interfere with driving safety.

[0270] Also, for example, based on the recognition that the vehicle (100) has started driving at a position corresponding to the front seat, the vehicle rear seat display device (800) can operate the first drive module (830a) to move the first and second displays (820a, 820b) in a first direction toward the rear seat, even if the first input signal is not received.

[0271] Also, for example, the control unit (850) can drive the first drive module (830a) to move the first and second displays (820a, 820b) in the first direction toward the rear seat regardless of the driving state of the vehicle. That is, the movement of the first and second displays (820a, 820b) in the first direction toward the rear seat can be performed without restriction.

[0272] Independently of the above step (S20), the vehicle rear seat display device (800) can control the second drive module (830b) to move the first and second displays (820a, 820b) in a second direction toward or away from each other in response to a second input signal (S30).

[0273] Here, the second input signal may include a control signal for moving the first and second displays (820a, 820b) closer to or farther away from each other, or may be a signal that triggers the generation of such a control signal. This second input signal may be generated by touching one of the specific buttons forming the input unit (870) (a button different from the specific button for generating the first input signal described above) or through a preset operation input.

[0274] In addition, the second direction here refers to a direction in which the gaps between the plurality of moving frames of the vehicle move closer or farther apart. Specifically, the second direction includes both a direction in which the plurality of moving frames (840) move closer to each other as a result of the driving of the second driving module (830b) and a direction in which the plurality of moving frames (840) that are in contact as a result of the driving of the second driving module (830b) move farther away from each other.

[0275] The second driving unit (830b) is arranged so that the plurality of moving frames (840) can move left and right (right and left) along guide rails (not shown) formed on the support frame on the back. In other words, the second driving unit (830b) is connected to one side of the fixed frame (801) of the ceiling and controls each of the moving frames (840a, 840b) arranged on the backs of the first and second displays (820a, 820b) so as to adjust the gap between the plurality of screens. In addition, the second driving unit (830b) may be equipped with a driving motor for providing driving force to the plurality of moving frames (840) for movement in the second direction.

[0276] In this way, after the first and second displays (820a, 820b) move independently in response to the first input signal and / or the second input signal, a plurality of screens are controlled based on each movement. That is, the rear seat display device (800) can control displayed screen information based on the movement of the first and second displays (820a, 820b) corresponding to at least one of the first and second input signals (S40).

[0277] Specifically, the vehicle rear seat display device (800) can operate to display different types of content based on the first and second displays (820a, 820b) moving forward and backward together in response to a first input signal. For example, when the first and second displays (820a, 820b) move to positions corresponding to the front seats, a content screen related to driving can be displayed with priority. In addition, when the first and second displays (820a, 820b) move to positions corresponding to the rear seats, an entertainment-related content screen can be displayed with priority. In addition, the vehicle rear seat display device (800) can operate to display different types of content based on the first and second displays (820a, 820b) moving left and right to get closer or farther apart in response to a second input signal.

[0278] Meanwhile, although not shown, the vehicle rear seat display device (800) according to an embodiment of the present invention can operate so that the first and second displays (820a, 820b) form a predetermined angle with respect to the fixed frame (801, FIG. 2) of the vehicle ceiling before and / or after the first and second displays (820a, 820b) move.

[0279] To this end, the vehicle rear seat display device (800) further includes an angle adjusting unit (860) that adjusts the degree of folding of the plurality of movable frames (840) so that the first and second displays (820a, 820b) form a predetermined angle with respect to the ceiling. Specifically, the control unit (850) can control the angle adjusting unit (860) to adjust the degree of folding of the plurality of movable frames so that the first and second displays (820a, 820b) form a predetermined angle between vertical and horizontal with respect to the ceiling of the vehicle in response to a first input signal.

[0280] In some embodiments, the control unit (850) of the vehicle rear seat display device (800) may control the angle adjustment unit to be driven at least at one point in time before and after the plurality of moving frames (840) move in response to the first input signal.

[0281] Specifically, the control unit (850) can adjust the angle adjustment unit (860) so that, in response to a first input signal, the plurality of moving frames (840) are folded to form a horizontal plane with respect to the ceiling, then move toward the front / rear seats while maintaining the folded state, and when the movement is completed, unfold to form a vertical plane or a predetermined angle with respect to the ceiling again.

[0282] To this end, the angle adjustment unit (860) may include a driving motor for performing folding / unfolding of the plurality of movable frames. The angle adjustment unit (860) may be disposed at a portion where the plurality of movable frames (840) are connected to the fixed frame (801) of the ceiling, specifically, at a connection portion where the support frame on the back of the plurality of movable frames (840) is connected to the fixed frame (801) of the ceiling. The angle adjustment unit (860) may move together with the plurality of movable frames (840) when the first and second displays (820a, 820b) move according to the first input signal.

[0283] In an embodiment, the control unit (850) of the vehicle rear seat display device (800) may control the operation of the angle adjustment unit (860) so that, in response to the first input signal, the plurality of moving frames (840) are folded before the first and second displays (820a, 820b) move in the first direction, and the plurality of moving frames (840) are unfolded after moving in the first direction.

[0284] While the first and second displays (820a, 820b) move in the first direction, the plurality of moving frames (840) can remain in a folded state. At this time, the first and second displays (820a, 820b) can remain in an inactive state.

[0285] In addition, when the first and second displays (820a, 820b) are completely moved in the first direction from the rear seat to the front seat, the plurality of moving frames (840) can be unfolded to have a predetermined angle (e.g., 60 to 45 degrees) between the horizontal and the vertical in consideration of the viewing angle of the passenger in the front seat. At this time, the predetermined angle means the angle formed between the back surface of the plurality of moving frames (840) and the ceiling (not the angle formed between the front surface of the plurality of screens and the ceiling). In addition, the predetermined angle may be a preset angle range in consideration of the viewing angle of the passenger in the front seat. When the angle adjustment for the first and second displays (820a, 820b) is completed in this way, the plurality of screens can be switched to an active state.

[0286] Additionally, when the first and second displays (820a, 820b) complete movement in the first direction from the front seat to the rear seat, the plurality of moving frames (840) can be unfolded to be perpendicular to the ceiling.

[0287] Also, in some embodiments, the first and second displays (820a, 820b) may be controlled to lean back the seat of the front seat (110) as they move in the first direction toward the front seat. Specifically, the control unit (850) of the vehicle rear seat display device (800) may generate a control signal for adjusting the seat angle of the front seat (110) of the vehicle and provide the control signal to the vehicle system in response to the first input signal when the first and second displays (820a, 820b) move together in the first direction. Meanwhile, as the first and second displays (820a, 820b) then move in the first direction toward the rear seat, the control signal for adjusting the seat angle of the front seat (110) of the vehicle may be generated and provided to the vehicle system so that the seat of the front seat (110) that was leaned back returns to its previous state.

[0288] In another embodiment, the control unit (850) of the vehicle rear seat display device (800) may receive information about the status and driving state of the vehicle through the communication unit (810), and determine whether to drive the second driving module (830b) in response to a second input signal based on the received information. Specifically, the control unit (850) may determine, based on the received vehicle status / driving state information, whether to move the first and second displays (820a, 820b) in a second direction toward each other in response to the second input signal. This is because, when the first and second displays (820a, 820b) move toward each other while forming a vertical position with the ceiling, the view of the rearview mirror of the driver's seat is blocked, making it difficult to check the rear vehicle. On the other hand, when the first and second displays (820a, 820b) move in the second direction away from each other, the control unit may be executed without limitation.

[0289] As described above, the vehicle rear seat display device (800) according to an embodiment of the present invention is implemented to move in different directions, so that rear seat passengers in the vehicle can use multiple screens independently or in full screen, and front seat passengers in the vehicle can also receive content services through multiple screens.

[0290] FIG. 7a, FIG. 7b, and FIG. 7c are drawings illustrating examples of an operation method when the first and second displays (820a, 820b) are used as independent screens.

[0291] In the initial state, the first and second displays (820a, 820b) may be horizontal with respect to the ceiling of the vehicle together with the plurality of movable frames (840). In this state, if there is a need for a rear seat passenger to use at least one of the first and second displays (820a, 820b) or if a second input signal is received, the plurality of movable frames (840) may be angle-adjusted to form a vertical position with respect to the ceiling. Thereafter, at least one screen of the first and second displays (820a, 820b) may be activated.

[0292] Referring to Fig. 7a, the first and second displays (820a, 820b) are arranged side by side behind the front seat (110) with a predetermined distance (L1) between them. While the first and second displays (820a, 820b) are separated by the distance (L1), each can be used as an independent screen. Accordingly, the first display (820a) can display a first screen (screen 1), and the second display (820b) can display a second screen (screen 2) that is different from the first screen.

[0293] Only one of the first and second displays (820a, 820b) may be activated, while the other one, which is not in use, may remain in an inactive state.

[0294] Referring to Fig. 7b, for example, if only the rear seat (left) passenger wishes to receive content services, the first display (820a) may remain activated, while the second display (820b) may be deactivated. At this time, a support frame (802) supporting a plurality of fixed frames is arranged on the rear surfaces of the spaced-apart first and second displays (820a, 820b). Furthermore, one side of the support frame (802) is connected to a fixed frame (801) on the vehicle ceiling.

[0295] In FIG. 7b, when a request for use is made to the second display (820b) while the first screen (701) is displayed on the activated first display (820a), the second display (820b) may also be switched to an activated state so that the second screen (702) may be displayed. At this time, the second screen (702) may be any type of content screen, regardless of the first screen (701).

[0296] FIG. 7c is an exemplary diagram illustrating a case where a screen is transmitted from an activated first display (820a) to an inactive second display (820b). For example, if a need arises to transmit the same screen to a passenger in the rear seat (right) while viewing the first screen (701) through the first display (820a), visual information (703) for accepting the screen transmission may be output to a portion of the second display (820b). In this case, based on a response to the visual information (703), the second display (820b) may be switched to an activated state, and the same screen as the first display (820a) may be output to the second display (820b).

[0297] Next, FIGS. 8a, 8b, 8c, and 8d are exemplary drawings for explaining a method of moving the first and second displays (820a, 820b) closer to each other and a screen control method accordingly.

[0298] When a second input signal is received while the first and second displays (820a, 820b) are spaced apart from each other by a predetermined distance, the first and second displays (820a, 820b) can move left and right to come closer to each other until their respective surfaces come into contact.

[0299] For example, referring to FIG. 8B, an input unit (870, FIG. 2) for receiving inputs for controlling movement of the first and second displays (820a, 820b) of the vehicle rear seat display device (800) may be disposed inside the vehicle (100) at a position spaced apart from the first and second displays (820a, 820b). The input unit (870) may be disposed, for example, in consideration of the distance and height that can be operated without changing the hand length, seat position, and posture of the passengers in the rear and front seats of the vehicle. In some embodiments, the input unit (870) may be disposed in each of the front and rear seats, or may be implemented as being included in a menu item of a touch screen.

[0300] For example, as illustrated in FIG. 8b, the input unit (870) may be implemented by including a plurality of buttons (e.g., “A, B, C, D, E”) that move the first and second displays (820a, 820b) in different directions or generate respective input signals for screen control.

[0301] For example, button 'A' can generate an input signal for operating the first and second displays (820a, 820b) in the initial state described above, button 'B' can generate an input signal for vertical tilting movement for screen use in the rear seat, button 'C' can generate a second input signal for moving multiple screens in a direction closer or farther away, button 'D' can generate an input signal for screen control for using multiple screens in full screen, and button 'E' can generate a first input signal including movement to the front seat (rear seat) and tilting movement of multiple screens.

[0302] The first and second displays (820a, 820b) can be operated to move in a second direction toward each other based on a second input signal. To this end, the control unit (850) can control the screen so that the first and second displays (820a, 820b) operate in full screen based on the fact that the first and second displays (820a, 820b) move in the second direction toward each other in response to the received second input signal while at least one of the first and second displays (820a, 820b) is activated.

[0303] Meanwhile, when the first and second displays (820a, 820b) move closer to each other and come into contact, for example, independent control can be driven to display screens of the same application maintained. For example, referring to FIGS. 8a and 8b, when an input is applied to the button 'C' described above in the input unit (870), multiple screens can be displayed in a battle screen mode. Specifically, the execution screens of the same game application can be displayed on the first and second displays (820a, 820b). Each screen is displayed according to the viewing angle of the matching passenger, and each passenger can independently control the screen. For example, the first display (820a) can display the game screen (901) of the first player, and the second display (820b) can display the game screen (902) of the second player of the same game.

[0304] Continuing, when the first and second displays (820a, 820b) are in contact, the plurality of screens can operate as a full screen displaying a single image. For example, referring to FIGS. 8b and 8c, when an input is applied to the button 'D' described above in the input unit (870), the plurality of screens can be switched to a full screen displaying a single image. Accordingly, as shown in FIG. 8c, a single image (903) is connected to and displayed on the first and second displays (820a, 820b). At this time, some frames within the single image (903) may be obscured or overlapped due to the right bezel of the first display (820a) and the left bezel of the second display (820b).

[0305] FIG. 8d illustrates a display that eliminates screen obscuration / discontinuity caused by the bezel when the first and second displays (820a, 820b) operate in full screen mode. To this end, the bezel portion that contacts the first and second displays (820a, 820b) is configured in the form of an LED bar, so that the screen can be controlled to cover the image output on the bezel with the same image frame. Accordingly, even when the first and second displays (820a, 820b) operate in full screen mode, a single image (904) can be displayed seamlessly.

[0306] Meanwhile, when a request is received to operate independently on the first and second displays (820a, 820b) and operate in full screen while different screens are displayed, the control unit (850) may be implemented to output an image output on one display in full screen on the entire first and second displays (820a, 820b) according to preset criteria.

[0307] Here, the preset criteria may be determined based on at least one of a display requesting a full screen, a priority of displayed content, a priority of control rights by seat, a default setting status, and a user setting. In the case where selection is determined based on the priority of displayed content, one of the screen information may be selectively displayed in full screen depending on the content type and execution status corresponding to the first screen information and the second screen information displayed on the first and second displays (820a, 820b), respectively. For example, if the first screen information displayed on the first display (820a) is a movie screen and the second screen information displayed on the second display (820b) is a menu screen, the movie screen of the first display (820a) may be selected as the full screen image.

[0308] Meanwhile, although not shown, the control unit (850) may control the screen so that each of the first and second displays (820a, 820b) operates as an independent screen again based on the fact that the first and second displays (820a, 820b) move away from each other in a second direction in response to a received second input signal while the first and second displays (820a, 820b) are operating in full screen while in contact.

[0309] For example, the control unit (850) may operate to re-display previous screen information that was previously displayed on each of the multiple screens or to return to a previous state (e.g., an inactive state). Alternatively, for example, depending on the content type (e.g., game content) and execution state (e.g., a battle mode in game content) of the full screen, the control unit may control the screens so that a screen that was previously being output as a single image is output equally on both screens.

[0310] In addition, in an embodiment, the control unit (850) may control the screen so that when only one of the first and second displays (820a, 820b) is activated, the other display is switched to an activated state based on the first and second displays (820a, 820b) moving in a second direction toward each other in response to a received second input signal, and the other display is switched back to an inactive state based on the first and second displays (820a, 820b) moving in a second direction away from each other in response to a subsequent second input signal.

[0311] In this way, the vehicle rear seat display device (800) according to an embodiment of the present invention can perform a movement motion in which multiple screens move closer or farther away from each other, and control the displayed content or screen status to adaptively change accordingly, thereby providing a display mode service that meets the needs of rear seat passengers.

[0312] Continuing, FIGS. 9a and 9b are exemplary drawings for explaining a method for moving the first and second displays (820a, 820b) to positions corresponding to the front seats of a vehicle, a screen control method according to the method, and an operation of a vehicle system.

[0313] The control unit (850) of the vehicle rear seat display device (800) can adjust the degree of folding of the plurality of moving frames (840) in response to the first input signal so that the first and second displays (820a, 820b) form a predetermined angle between vertical and horizontal with respect to the ceiling.

[0314] Specifically, the control unit (850) recognizes the current positions of the first and second displays (820a, 820b) based on the received first input signal, and determines whether to move the plurality of moving frames (840) toward the front seats or the rear seats according to the received first input signal. Then, if the first and second displays (820a, 820b) are not in a state of forming a horizontal plane with the fixed frame (801) of the ceiling, the control unit performs a folding operation so that the plurality of moving frames (840) form a horizontal plane with the fixed frame (801). Then, the control unit controls the operation of the first driving module (830a) so that the plurality of moving frames (840) in a folded state according to the determined direction move along the longitudinal direction of the fixed frame (801) of the ceiling. According to the driving of the motor included in the first driving module (830a), driving force is transmitted to the plurality of moving frames (840), and the plurality of moving frames (840) move in the first direction. When the movement of the plurality of moving frames (840) is completed, the plurality of moving frames (840) perform an unfolding operation so that the plurality of moving frames (840) form a vertical line with the fixed frame (801) or the back surface and the ceiling of the plurality of moving frames (840) form a predetermined angle (e.g., 60).

[0315] Meanwhile, the control unit (850) of the vehicle rear seat display device (800) can control the display of the first type of screen while the first and second displays (820a, 820b) are at positions corresponding to the rear seats of the vehicle, and change the first type of screen to a second type of screen related to driving of the vehicle based on the first and second displays (820a, 820b) moving to positions corresponding to the front seats of the vehicle according to the driving of the first driving module (830a). Here, the first type of screen can be any type of content selected by the rear seat passenger. In addition, the second type of screen can include, for example, the vehicle's navigation screen.

[0316] FIG. 9a is an example showing that the screens displayed on the first and second displays (820a, 820b) change after the plurality of moving frames (840) move from the rear seats toward the front seats. For example, as shown in FIG. 8d, when a movie screen (904) is displayed in full screen on the first and second displays (820a, 820b) in the rear seats and then moves toward the front seats, the vehicle's driving screen (905) can be displayed in full screen.

[0317] Meanwhile, when the first and second displays (820a, 820b) move toward the front seat or after the movement is completed, the vehicle rear seat display device (800) communicates with the vehicle system so that a control signal can be transmitted from the vehicle rear seat display device (800) to the vehicle system so that the front seat backrest is leaned back.

[0318] Referring to FIG. 9B, when the first and second displays (820a, 820b) move to positions corresponding to the front seats in response to the first input signal, an unfolding operation of the plurality of frames (840) is performed by the angle adjusting unit (860). According to the unfolding operation, the plurality of frames (840) are rotated to bend backward toward the windshield of the vehicle, and the rear surfaces of the plurality of frames (840) and the ceiling of the vehicle are adjusted to form a predetermined angle, for example, about 60 degrees. In this way, when the first and second displays (820a, 820b) move toward the front seats and pass the midpoint or after the movement is completed, the seat back of the front seats (110) is leaned back by the vehicle system to form a predetermined angle (L4). Here, the predetermined angle (L4) may range, for example, from 20 to 30 degrees, and this value may vary depending on the current angle of the seat backrest and the sensing value of a sensor (e.g., a weight sensor) mounted on the seat. In addition, if the front seat (110) is already reclined, the lean-back operation may be omitted.

[0319] FIG. 10 is a flowchart illustrating the screen control and the operation process of the vehicle system when the first and second displays (820a, 820b) are moved to positions corresponding to the front seats of the vehicle. All or part of the operations illustrated in FIG. 10 may be combined with and performed in conjunction with the operations of the flowchart of FIG. 6. In addition, unless otherwise stated, it is assumed that the operations of FIG. 10 are performed by the control unit (850) (or processor (850)) of the vehicle rear seat display device (800).

[0320] Referring to FIG. 10, the vehicle rear seat display device (800) can generate a control signal for adjusting the seat angle of the front seat of the vehicle and provide it to the vehicle system when the first and second displays (820a, 820b) move together in the first direction in response to the first input signal (S25).

[0321] Specifically, the control unit (850) can provide a first control signal to the vehicle system to adjust the seat of the front seat (110) to be tilted backward when the first and second displays (820a, 820b) move toward the front seat of the vehicle. The vehicle system can control the backrest seat of the front seat (110) of the vehicle to be tilted back about 20 to 30 degrees from the vertical based on the first control signal.

[0322] Similarly, when the first and second displays (820a, 820b) move toward the rear of the vehicle, the control unit (850) may provide a second control signal to adjust the seat of the front seat (110) to be pulled forward and restored to its previous state. The vehicle system may operate the seat back of the front seat (110) of the vehicle to be restored to its vertical position or to its initial setting state from its lean-back state based on the second control signal.

[0323] Meanwhile, although not described in detail, when the first and second displays (820a, 820b) are moved toward the rear of the vehicle, the rear seat of the vehicle may be adjusted to recline backward. In this case, when the first and second displays (820a, 820b) are moved toward the front of the vehicle or folded to form a level with the fixed frame (801) of the ceiling, the lean-backed rear seat backrest may be restored to its original state.

[0324] Independently of the above step (S25), the vehicle rear seat display device (800) can operate to automatically change the display mode of the first and second displays (820a, 820b) based on the first and second displays (820a, 820b) moving in the second direction to get closer or farther away from each other in response to the second input signal (S45).

[0325] Specifically, based on the first and second displays (820a, 820b) moving in a second direction toward each other, the control unit (850) can control the screen so that the first and second displays (820a, 820b) operate in a match mode or a full screen mode.

[0326] For example, when a game application is running on one of the first and second displays (820a, 820b), and the first and second displays (820a, 820b) move closer to each other and one side touches, the screens of each of the first and second displays (820a, 820b) may be switched to a game battle mode screen. Alternatively, when a movie screen is displayed on one of the first and second displays (820a, 820b), and the first and second displays (820a, 820b) move closer to each other and one side touches, the movie screen may be displayed in full screen on the first and second displays (820a, 820b).

[0327] As described above, according to the vehicle rear seat display device and its operating method according to an embodiment of the present invention, as the multiple screens located in the rear seat of the vehicle move toward or away from each other, the display modes of the screens change, allowing the rear seat passengers to use them as independent screens or multi-screens according to their needs. Accordingly, the user experience utilizing the multiple screens is further expanded. Furthermore, by implementing the multiple screens located in the rear seat of the vehicle to be able to move toward or back toward the front seats, the rear seat screens can also be used by the front seat passengers when necessary. Accordingly, the limited number of displays can be shared by more passengers, expanding the user experience and maintaining a simple vehicle interior design. Furthermore, as the multiple screens move, the display mode automatically changes to match the viewing intent of the vehicle passengers, and the seat leans back in parallel, enabling more comfortable content viewing in the vehicle. In addition, in consideration of the driving safety of the vehicle, the movement of multiple screens to the front seats while the vehicle is in motion is restricted, and the combination of multiple screens in the rear seats is restricted during manual driving, thereby satisfying both the needs of passengers and driving safety.

[0328] The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc., and also includes media implemented in the form of carrier waves (e.g., transmission via the Internet). In addition, the computer may include a controller / processor of a vehicle display device (800). Therefore, the above detailed description should not be construed as limiting in all respects, but should be considered as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are intended to be included in the scope of the present invention.
