[0194] In embodiments of the present invention, the "vehicle rear seat display device" can be configured as a display device arranged in the rear seat of the vehicle 100, and is capable of moving in different directions from each other. The vehicle rear seat display device can have a plurality of drive modules for moving in different directions from each other. In addition, the vehicle rear seat display device can be configured to tilt to a predetermined angle with respect to the vehicle ceiling.

[0195] Figure 2 This is a diagram showing a vehicle rear seat display device 800 installed inside a vehicle 100 according to an embodiment of the present invention.

[0196] like Figure 2As shown, the vehicle rear seat display device 800 can be configured such that a plurality of movable frames 840a and 840b are connected to a fixed frame 801 disposed on the ceiling of the vehicle 100 from the front seat 110 toward the rear seat, and a first display 820a and a second display 820 are respectively arranged on the front of the plurality of movable frames 840a and 840b.

[0197] On the other hand, an angle adjustment unit 860 can be installed on the back of the plurality of movable frames 840 to adjust the angle of the first display 820a and the second display 820b. Depending on the operation of the angle adjustment unit 860, the first display 820a and the second display 820b can be horizontally aligned with the fixed frame 801 or vertically aligned as shown in the figure.

[0198] A plurality of movable frames 840 are configured to move in different directions from each other. Thus, the first display 820a and the second display 820b arranged on the front of each of the plurality of movable frames 840 can move in different directions from each other.

[0199] Specifically, the plurality of movable frames 840 can move along the length of the fixed frame 801 provided on the ceiling toward the front of the front seat or toward the rear of the front seat (or the front of the rear seat). As a result, the first display 820a and the second display 820b move toward the front of the front seat or to the front of the rear seat of the vehicle 100.

[0200] Furthermore, the plurality of movable frames 840 can move closer to or further away from each other. Thus, the spacing between the first display 820a and the second display 820b is adjusted to be closer to (or in contact with) or further away from each other.

[0201] If the first display 820a and the second display 820b are located in front of the front seat as the plurality of movable frames 840 move to the front side of the front seat, the occupant of the front seat (driver and / or front passenger) can receive content services through the first display 820a and the second display 820b.

[0202] On the other hand, in multiple mobile frames 840, such as Figure 2 In such a configuration, the rear seat occupants of vehicle 100 can receive content services via the first display 820a and the second display 820b.

[0203] Furthermore, when the first display 820a and the second display 820b are separate from each other, the rear seat occupants of the vehicle 100 can use the first display 820a and the second display 820b as independent screens to receive content services. That is, the occupant on the left side of the rear seat can receive content services through the first display 820a, and the occupant on the right side of the rear seat can receive other content services through the second display 820b.

[0204] On the other hand, if the distance between the first display 820a and the second display 820b is adjusted to be close, the first display 820a and the second display 820b as a whole can operate in full-screen mode. That is, if the first display 820a and the second display 820b are close to each other and touch, they can switch to full-screen mode without additional screen control.

[0205] In another embodiment, if it is determined that there is no intention to use the first display 820a and the second display 820b, folding can be performed according to the action of the angle adjustment unit 860 so that the plurality of movable frames 840 are horizontal with the fixed frame 801 as a reference.

[0206] Figure 2 In the plurality of movable frames 840 shown, the state in which they are perpendicular to the fixed frame 801 is defined as the "unfolding state". Additionally, although not shown, the state in which the plurality of movable frames 840 are horizontal to the fixed frame 801 is defined as the "folding state".

[0207] Reference Figure 2 The portions of the plurality of movable frames 840 connected to the fixed frame 801 remain fixed, and the plurality of movable frames 840 rotate significantly toward the fixed frame 801 as if bending until they are horizontal with the fixed frame 801, thereby switching from the "unfolding state" to the "folding state".

[0208] As described above, the vehicle rear seat display device 800 of this embodiment of the invention is movable between the front seat and the rear seat, and the plurality of displays are movable toward or away from each other, so that all passengers in the vehicle 100 can receive content services through the rear seat display device 800.

[0209] Figure 3 This is a block diagram illustrating the detailed configuration of the vehicle rear seat display device 800 according to an embodiment of the present invention.

[0210] The vehicle rear seat display device 800 may include a communication unit 810, a first display 820a and a second display 820b, a first drive module 830a and a second drive module 830b, a plurality of movable frames 840, a control unit 850, an angle adjustment unit 860, and an input unit 870. Furthermore, the vehicle rear seat display device 800 can be communicatively connected to a system within the vehicle 100 via the communication unit 810.

[0211] The communication unit 810 communicates with the vehicle 100, the systems inside the vehicle 100, various sensors inside the vehicle 100, ADAS (Advanced Driver Assistance Systems), DMS (Driver Monitoring System), and other devices, thereby receiving vehicle data and vehicle driving data.

[0212] Additionally, the communication unit 810 can receive input signals corresponding to inputs applied to input devices installed within the vehicle 100 and transmit them to the control unit 850. For example, the communication unit 810 can receive signals related to the drive of at least one of the first drive module 830a and the second drive module 830b of the rear seat display device 800 from input devices linked within the vehicle 100.

[0213] The rear-seat vehicle display device 800 includes a first display 820a and a second display 820b, each with a separate frame. The first display 820a and the second display 820b can display different images, the same images, or a connected image, respectively.

[0214] The first display 820a and the second display 820b can be arranged on the front sides of a plurality of movable frames 840 arranged side by side. In other words, movable frames that are movably formed can be attached to the back sides of the first display 820a and the second display 820b, respectively. Thus, as the plurality of movable frames 840 move, the attached first display 820a and the second display 820b can also move together.

[0215] When the first display 820a and the second display 820b are used as independent screens, the screen can be controlled independently. Alternatively, when the first display 820a and the second display 820b are used as a full screen, unified screen control can be performed.

[0216] In this embodiment, screen control of the first display 820a and the second display 820b can be performed based on movement driven by the first driving module 830a and the second driving module 830b. For example, when the first display 820a and the second display 820b move forward or backward according to the drive of the first driving module 830a, the type of content displayed can be changed. Additionally, for example, when the first display 820a and the second display 820b move closer to or further away from each other according to the drive of the second driving module 830b, the screen mode of the display (e.g., full-screen mode) can be changed.

[0217] The first drive module 830a and the second drive module 830b provide driving forces for moving the plurality of movable frames 840 to move the first display 820a and the second display 820b along a first direction or along a second direction. Specifically, the first drive module 830a can transmit driving forces to the plurality of movable frames 840 to move the first display 820a and the second display 820b together along the first direction, i.e., towards the front seat or towards the rear seat. Additionally, the second drive module 830b can provide driving forces to the plurality of movable frames 840 to move the first display 820a and the second display 820b along the second direction, i.e., towards each other or away from each other.

[0218] A first display 820a and a second display 820b are respectively arranged on the front of a plurality of movable frames 840. One side of the plurality of movable frames 840 is connected to the fixed frame 801 of the vehicle ceiling for the front and rear seats. Figure 2 One side of the fixed frame 801 is connected to the ground. Thus, when the first drive module 830a is driven, the plurality of movable frames 840 can move along the length direction of the fixed frame 801.

[0219] A plurality of movable frames 840 are arranged side by side at predetermined intervals and supported by the same support frame located at the rear. Thus, when the second drive module 830b is driven, the plurality of movable frames 840 can move closer to each other or move back to the predetermined intervals.

[0220] The control unit 850 controls the overall operation of the vehicle rear seat display device 800. The control unit 850 may be named a processor or PC, and may be arranged, for example, in a cover located between the front seats inside the vehicle 100.

[0221] The control unit 850 can control the driving of the first driving module 830a and the second driving module 830b, as well as the display screens of the first display 820a and the second display 820b. In an embodiment, the control unit 850 can control the first driving module 830a to move the first display 820a and the second display 820b together along a first direction in response to a first input signal. Additionally, the control unit 850 controls the second driving module 830b to move the first display 820a and the second display 820b along a second direction different from the first direction in response to a second input signal different from the first input signal, thereby moving them away from or closer to each other.

[0222] Angle adjustment unit 860 can be arranged on a fixed frame located behind the plurality of movable frames 840 and a fixed frame 801 formed in the ceiling of the vehicle. Figure 2 )between.

[0223] Angle adjustment unit 860 is coupled to one side of a plurality of movable frames 840, thereby enabling the plurality of movable frames 840 to move to form a predetermined angle with reference to fixed frame 801. Specifically, angle adjustment unit 860 provides a driving force for rotating the plurality of movable frames 840 so that the plurality of movable frames 840 form a horizontal, vertical, or a set angle between the plurality of movable frames 840 and fixed frame 801.

[0224] The input unit 870 may be arranged separately from the first display 820a and the second display 820b on one side of the vehicle 100. In order to control the movement direction of the first display 820a and the second display 820b, the input unit 870 may include a plurality of buttons corresponding to each direction or include an operating unit capable of tilting / moving in a plurality of directions.

[0225] In this embodiment, if a first input signal is generated based on a first input to the input unit 870, the control unit 850 can control the first drive module 830a to drive the first display 820a and the second display 820b together to move along a first direction. Alternatively, if a second input signal is generated based on a second input to the input unit 870, the control unit 850 can control the first display 820a and the second display 820b to move along a second direction, moving closer to or further away from each other, by driving the second drive module 830b.

[0226] Figure 4 This is a conceptual diagram illustrating the compatibility of the movement of the rear seat display device 800 and the front seat display device according to an embodiment of the present invention.

[0227] The rear seat display device 800 can be used by the rear seat occupants, or it can be moved towards the front seat for the front seat occupants to use.

[0228] Therefore, the rear seat display device 800 can communicate with other display devices located in the front seats via a router. Additionally, the rear seat display device 800 can determine whether to move based on the communication results with other display devices.

[0229] Specifically, if an input, such as a hard key or a touch screen, is received from the input section 870 of the rear display device 800, the first processor 850a can transmit the signal corresponding to the received input to the second processor 850b via a router. In this case, the first processor 850a can be, for example, an NVIDIA SYSTEM, and the second processor 850b can be, for example, a mini PC.

[0230] As another example, the first processor 850a can directly transmit the signal corresponding to the received input to the first drive module 830a as a drive signal for the forward / backward movement of the first display 820a and the second display 820b. This drives the motor of the first drive module 830a, thereby generating a driving force for moving the first display 820a and the second display 820b in the forward / backward direction.

[0231] on the other hand, Figure 4 The functions of the first processor 850a and the second processor 850b shown can be implemented such that they can be interchanged or separate to perform a portion of the action, or be performed by one processor 850.

[0232] Additionally, inputs with the same requests as those for the input unit 870 can also be made via the display in the front seat of the vehicle 100 or the operating unit in the front seat. In this case, similarly as described above, the signal corresponding to the input is transmitted via a router to the processor of the rear seat display device 800, thereby actuating the motor of the first drive module 830a to move the first display 820a and the second display 820b back and forth.

[0233] In addition, the vehicle rear seat display device 800 can be used as a plurality of independent screens for rear seat passengers to use individually, or it can be used as a full screen so that the plurality of screens can be moved close to each other to display a connected image.

[0234] Therefore, such as Figure 4 As shown, the vehicle rear seat display device 800 transmits signals corresponding to other inputs applied to the input unit 870 to the first processor 850a and / or the second processor 850b (or processor 850), which can drive the motor of the second drive module 830b to bring the first display 820a and the second display 820b closer to or further away from each other.

[0235] At this time, the movable frames 840, which are equipped with the first display 820a and the second display 820b, are respectively arranged. Figure 2 Each of the moving frames 840 has an independent drive motor, and the multiple motors matched with each moving frame 840 rotate in opposite directions, causing the multiple moving frames 840 to gradually move closer to or further away from each other.

[0236] Additionally, in this embodiment, the rear seat display device 800 can adjust the angle adjustment section 860 so that the first display 820a and the second display 820b are arranged on the fixed frame 801 of the ceiling of the vehicle 100. Figure 2The reference is to form a predetermined angle. The angle adjustment unit 860 drives the motor to form an angle between the plurality of moving frames 840 and the fixed frame 801 in the range of horizontal, vertical or horizontal and vertical, so that the first display 820a and the second display 820b can be tilted.

[0237] For example, when the first display 820a and the second display 820b of the rear seat display device 800 are moved to the front side of the vehicle's front seat, the router can transmit the information to the front seat display and system to activate the angle adjustment unit 860 so that the plurality of movable frames 840 form a predetermined angle between the horizontal and vertical sides with the fixed frame 801.

[0238] Additionally, for example, before the first display 820a and the second display 820b of the vehicle rear seat display device 800 move toward the front of the front seat or the front of the rear seat of the vehicle, the angle adjustment unit 860 can be activated to make the plurality of movable frames 840 form a horizontal position with the fixed frame 801.

[0239] On the other hand, although not shown in detail, when the front seat display is activated while the vehicle is in motion, the processor 850 can limit the drive of the first drive module 830a to prevent the first display 820a and the second display 820b of the rear seat display device 800 from moving towards the front of the vehicle's front seats. This does not compromise driving safety.

[0240] Similarly, when the vehicle is in manual driving mode and the front seat display is activated, the processor 850 can restrict the drive of the second drive module 830b to prevent the first display 820a and the second display 820b of the rear seat display device 800 from moving closer to each other. Thus, when the driver is manually driving, the first display 820a and the second display 820b do not obstruct the rearview mirror.

[0241] As described above, the vehicle rear seat display device 800 of this embodiment is driven in conjunction with the vehicle's front seat display to move the first display 820a and the second display 820b in different directions or form a predetermined angle, thereby providing further expanded usability. Furthermore, by restricting the movement of the first display 820a and the second display 820b according to the operation of the front seat display based on the vehicle's driving state, services can be provided while considering vehicle driving safety.

[0242] the following, Figure 5a , Figure 5b , Figure 5c , Figure 5d This is a concept diagram for moving and adjusting the angle of the rear seat display devices 800 in different directions.

[0243] The rear seat display device 800 moves from a position corresponding to the rear seat of the vehicle toward or away from each other, so that a unified full screen or multiple independent screens can be used.

[0244] In addition, the rear seat display device 800 can be moved to a position corresponding to the front seats of the vehicle or moved back to a position corresponding to the rear seats, thereby providing expanded usability so that both rear seat occupants and front seat occupants can utilize multiple screens.

[0245] Furthermore, when the rear seat display device 800 is not in use and is used by the front seat occupant of the vehicle, it operates by forming multiple screens at a predetermined angle, thereby effectively utilizing the vehicle space and providing a convenient viewing angle for the front seat occupant.

[0246] Figure 5a This is an example diagram showing the initial state of the vehicle rear seat display device 800.

[0247] In the initial state of the vehicle rear seat display device 800, the first display 820a and the second display 820b are located behind the front seat (or in front of the rear seat) of the vehicle, with one side attached to the fixed frame 801 of the ceiling. Figure 2 They combine to maintain a horizontal state. Thus, as... Figure 5a As shown in (a), a plurality of movable frames 840a, 840b face the ceiling of the vehicle, as... Figure 5a As shown in (b), the front of the first display 820a and the second display 820b faces the bottom of the vehicle.

[0248] Figure 5b This is an example diagram showing the state in which rear seat passengers are using the vehicle rear seat display device 800. That is, it is an example of the first display 820a and the second display 820b of the vehicle rear seat display device 800 being used as independent multiple screens in the rear seat.

[0249] The first display 820a and the second display 820b are kept apart by a specified separation distance L1, and are held in place by the fixed frame 801 of the ceiling. Figure 5a (a) is the state of being perpendicular to the baseline.

[0250] In this configuration, the first display 820a is for the passenger on the left side of the rear seat, and the second display 820b is for the passenger on the right side of the rear seat. Furthermore, only one of the first display 820a and the second display 820b can be activated, while the other remains deactivated. Additionally, the first display 820a and the second display 820b can function as separate, multiple screens, and can also display the same content simultaneously. Furthermore, in this embodiment, the displayed image can be transmitted from one of the first display 820a and the second display 820b to the other.

[0251] in addition, Figure 5b In this configuration, a plurality of movable frames 840a and 840b are located behind the first display 820a and the second display 820b and face the front seat (b) of the vehicle 100. Furthermore, an angle adjustment unit 860, which is combined with a portion of the plurality of movable frames 840a and 840b and a portion of the fixed frame 801, is supported to maintain the plurality of movable frames 840a and 840b in a horizontal position relative to the fixed frame 801.

[0252] Figure 5c This is an example diagram showing the state in which multiple screens of the rear-mounted display device 800 move close to each other and operate in full-screen mode.

[0253] Each of the plurality of movable frames 840a, 840b has a motor, and the linked motors rotate in different directions according to the control signal of the processor 850, so that the first display 820a and the second display 820b move in a direction L2 toward each other (a). When one side of the first display 820a and the second display 820b comes into contact with each other, the driving of the linked motors is interrupted. The processor 850 can control the screen so that the first display 820a and the second display 820b display an image in full screen or display the execution screen of the same application on the plurality of screens.

[0254] During the movement of the plurality of movable frames 840a, 840b toward each other according to the action of the second drive module 830b located on the rear, the fixed frame 801 of the ceiling, the angle adjustment part 860 connected thereto, and the fixed frame on the rear of the second drive module 830b support the plurality of movable frames 840a, 840b(b).

[0255] On the other hand, such as Figure 5cAs shown, the movement of the first display 820a and the second display 820b closer to each other can be an action performed before the first display 820a and the second display 820b move towards the front side of the vehicle's front seat. In other words, during the forward / backward movement of the plurality of movable frames 840 along the length direction of the fixed frame 801 of the ceiling, the first display 820a and the second display 820b remain in contact with each other and move together.

[0256] then, Figure 5d This is an example diagram showing a state in which multiple screens of the rear seat display device 800 move toward the front seat and can be used by the occupant of the front seat.

[0257] Reference Figure 5d Driven by the first drive module 830a, the first display 820a and the second display 820b move toward the front seat 110 along the length direction L3 of the fixed frame of the vehicle ceiling. At this time, the front of the first display 820a and the second display 820b faces the bottom, and the plurality of moving frames are tilted toward the ceiling, moving in a folded state facing the fixed frame 801 of the ceiling (a).

[0258] If the movement is completed at the end of the length direction L3 of the fixed frame 801, the action is to unfold the first display 820a and the second display 820b at an angle that the occupant of the front seat 110 can see and hear, forming a predetermined angle (d) with the fixed frame 801 of the ceiling.

[0259] On the other hand, although not shown, a similar movement can be performed when the first display 820a and the second display 820b move from the front seat 110 toward the rear seat. Specifically, after the first display 820a and the second display 820b, which are tilted for the occupants of the front seat 110, are folded back into a horizontal position relative to the ceiling's fixed frame 801, they move toward the rear seat along the length L3 of the fixed frame 801. If the movement is completed at the end of the length L3 of the fixed frame 801, it can be unfolded perpendicularly to the ceiling's fixed frame 801 to maintain a reference position. Figure 5a The initial state of the description or the ability for rear-seat passengers to utilize it.

[0260] Figure 6 This is a representative flowchart illustrating the operation method of the vehicle rear seat display device 800 according to an embodiment of the present invention. Figure 6 The various actions shown can be performed by the control unit 850 (or processor 850) unless otherwise specified. Additionally, in some embodiments, where the vehicle rear seat display device 800 is included as part of the vehicle system, it can be performed by the vehicle system's control unit / processor.

[0261] The rear seat display device 800 can be initially positioned behind the back of the front seat 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 side-by-side movable frames 840. At this time, one side of the plurality of movable frames 840 is connected to a fixed frame 801 of the vehicle 100 ceiling. Figure 2 The first display 820a and the second display 820b located on the front are combined on one side and can be supported by the fixed frame 801 when using and moving.

[0262] In the initial state, the first display 820a and the second display 820b can remain folded in the deactivated state to form a horizontal alignment with the fixed frame 801 of the ceiling. Then, if a passenger in the rear seat of the vehicle 100 requests to use at least one of the first display 820a and the second display 820b, the first display 820a and the second display 820b can be unfolded to form a vertical alignment with the fixed frame 801.

[0263] In some embodiments, if a passenger in the back seat of the vehicle is sensed, it is determined that there is a use request for at least one of the first display 820a and the second display 820b, so that the first display 820a and the second display 820b can be unfolded to form a vertical arrangement with reference to the fixed frame 801.

[0264] In the aforementioned initial state, the angle adjustment unit 860 of the rear seat display device 800 provides driving force for the unfolding action to the plurality of movable frames 840 so that the plurality of movable frames 840 are perpendicular to the fixed frame 801 of the ceiling. As a result, according to the unfolding action of the plurality of movable frames 840, the first display 820a and the second display 820b arranged on the front unfold, so that the plurality of screens face the rear seat occupant.

[0265] The control unit 850 of the vehicle rear seat display device 800 controls the screen at a position corresponding to the rear seat of the vehicle to display screen information on at least one of the first display 820a and the second display 820b (S10).

[0266] Once the first display 820a and the second display 820b have been fully deployed, at least one of the first display 820a and the second display 820b switches from a deactivated state to an activated state. In some embodiments, the vehicle rear seat display device 800 can also be activated through interaction such as screen touch on the first display 820a and the second display 820b.

[0267] Next, in response to the first input signal, the vehicle rear seat display device 800 controls the first drive module 830a to move the first display 820a and the second display 820b together in the first direction (S20).

[0268] Here, the first input signal may include a control signal for moving the first display 820a and the second display 820b together from one of the front seat and the rear seat to the other, or a signal that triggers the generation of such a control signal. This first input signal is generated by touching a specific button forming the input section 870 or by a preset operation input.

[0269] Additionally, here, the first direction refers to the length direction of the fixed frame 801 connecting the ceiling of the front and rear seats of the vehicle. Specifically, the first direction includes the direction in which the plurality of movable frames 840 move from the rear seat to the front seat according to the drive of the first drive 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 drive of the first drive module 830a.

[0270] The first drive unit 830a is capable of moving along a guide rail (not shown) of a first fixed frame 801 arranged on the ceiling, together with a plurality of movable frames 840. Additionally, the first drive unit 830a may have a drive motor for providing a driving force to the plurality of movable frames 840 for movement in a first direction.

[0271] On the other hand, in another embodiment, the operation of the first drive module 830a corresponding to the first input signal can be limited according to the vehicle's driving state. Specifically, the communication unit 810 of the vehicle rear seat display device 800 receives information about the vehicle's status and driving state from the vehicle 100 and transmits it to the control unit 850. Then, the control unit 850 determines, based on the received information, whether to move the first display 820a and the second display 820b together along the first direction.

[0272] For example, if the vehicle 100 is moving at the time the first input signal is received, the control unit 850 can restrict the drive of the first drive module 830a to prevent the first display 820a and the second display 820b from moving in the first direction toward the front seat. That is, the first drive module 830a can be activated only when the vehicle 100 is stationary, so that the first display 820a and the second display 820b move in the first direction toward the front seat. Thus, while the vehicle is moving, the plurality of screens do not move toward the front seat, thereby not interfering with driving safety.

[0273] Additionally, for example, at the position of the rear seat display device 800 corresponding to the front seat, based on the recognition that the vehicle 100 has started to move, even without receiving the first input signal, it can be operated to drive the first drive module 830a so that the first display 820a and the second display 820b move in a first direction toward the rear seat.

[0274] Furthermore, for example, the control unit 850 can execute the drive of the first drive module 830a for moving the first display 820a and the second display 820b in a first direction toward the rear seat, regardless of the vehicle's driving state. That is, the movement of the first display 820a and the second display 820b in the first direction toward the rear seat can be performed without restriction.

[0275] Independent of step S20 described above, the vehicle rear seat display device 800 may, in response to a second input signal, control the second drive module 830b to move the first display 820a and the second display 820b along a second direction that moves away from or closer to each other (S30).

[0276] Here, the second input signal may include a control signal for moving the first display 820a and the second display 820b closer to or further away from each other, or a signal triggered to generate such a control signal. This second input signal may be generated by touching one of the specific buttons forming the input section 870 (other buttons that are distinct from the specific button used to generate the aforementioned first input signal) or by a pre-set operation input.

[0277] Furthermore, here, the second direction refers to the direction in which the spacing between the plurality of movable frames of the vehicle moves away from or towards each other. Specifically, the second direction includes the movement direction in which the plurality of movable frames 840 move closer to each other according to the drive of the second drive module 830b, and the movement direction in which the plurality of contacting movable frames 840 move away from each other according to the drive of the second drive module 830b.

[0278] The second drive unit 830b is arranged such that a plurality of movable frames 840 can move left and right (right-left) respectively along guide rails (not shown) formed on the support frame on the back side. In other words, the second drive unit 830b is connected to one side of the fixed frame 801 of the ceiling, thereby adjusting the spacing between the plurality of screens by controlling the respective movable frames 840a, 840b arranged on the back of the first display 820a and the second display 820b. In addition, the second drive unit 830b may be provided with a drive motor that provides driving force to the plurality of movable frames 840 for movement in a second direction.

[0279] As described above, in response to the first input signal and / or the second input signal, after the first display 820a and the second display 820b move independently, a plurality of screens are controlled based on each movement. That is, the rear-seat display device 800 can control the displayed screen information according to the movement of the first display 820a and the second display 820b corresponding to at least one of the first input signal and the second input signal (S40).

[0280] Specifically, the rear-seat display device 800 can move together, with the first display 820a and the second display 820b moving back and forth based on a first input signal, to display different types of content. For example, if the first display 820a and the second display 820b move to a position corresponding to the front seats, driving-related content can be displayed first. Conversely, if the first display 820a and the second display 820b move to a position corresponding to the rear seats, entertainment-related content can be displayed first. Furthermore, the rear-seat display device 800 can also move left and right, with the first display 820a and the second display 820b moving closer or further apart, based on a second input signal, to display different types of content.

[0281] On the other hand, although not shown, the vehicle rear seat display device 800 of this embodiment can be operated such that, before and / or after the first display 820a and the second display 820b are moved, the first display 820a and the second display 820b are fixed to the vehicle ceiling frame 801 ( Figure 2 The specified angle is formed based on the reference.

[0282] To this end, the vehicle rear seat display device 800 also includes an angle adjustment unit 860 that adjusts the folding degree of a plurality of movable frames 840 so that the first display 820a and the second display 820b form a predetermined angle with respect to the ceiling. Specifically, in response to a first input signal, the control unit 850 can control the angle adjustment unit 860 to adjust the folding degree of the plurality of movable frames so that the first display 820a and the second display 820b form a predetermined angle between vertical and horizontal with respect to the vehicle ceiling.

[0283] In some embodiments, the control unit 850 of the vehicle rear seat display device 800, in response to a first input signal, controls the drive angle adjustment unit at at least one time point before and after the movement of the plurality of movable frames 840.

[0284] Specifically, in response to the first input signal, the control unit 850 causes the plurality of movable frames 840 to fold horizontally relative to the ceiling, maintain the folded state, and move toward the front / rear seat. Once the movement is complete, the angle adjustment unit 860 can be adjusted to unfold the frames and re-establish a vertical or predetermined angle relative to the ceiling.

[0285] For this purpose, the angle adjustment unit 860 may include a drive motor for performing the folding / unfolding of the plurality of movable frames. The angle adjustment unit 860 may be arranged at the portion where the plurality of movable frames 840 are joined to the ceiling's fixed frame 801, specifically at the connection portion where the support frame on the back of the plurality of movable frames 840 engages with the ceiling's fixed frame 801. The angle adjustment unit 860 may move together with the plurality of movable frames 840 when the first display 820a and the second display 820b move according to a first input signal.

[0286] In an embodiment, the control unit 850 of the vehicle rear seat display device 800 responds to a first input signal and controls the drive of the angle adjustment unit 860 so that a plurality of movable frames 840 are folded before the first display 820a and the second display 820b move in a first direction, and the plurality of movable frames 840 are unfolded after they move in the first direction.

[0287] During the movement of the first display 820a and the second display 820b along the first direction, the plurality of movable frames 840 can remain in a folded state. At this time, the first display 820a and the second display 820b can remain in a deactivated state.

[0288] Furthermore, once the first display 820a and the second display 820b have completed their movement along a first direction from the rear seat to the front seat, the plurality of movable frames 840 can be deployed to a predetermined angle (e.g., 60-45 degrees) between the horizontal and vertical, taking into account the viewing angle of the front seat occupant. In this case, the predetermined angle (not the angle formed by the front of the plurality of screens and the ceiling) refers to the angle formed between the back of the plurality of movable frames 840 and the ceiling. Additionally, considering the viewing angle of the front seat occupant, the predetermined angle can be a pre-set angle range. As described above, once the angle adjustment for the first display 820a and the second display 820b is completed, the plurality of screens can be switched to an active state.

[0289] Additionally, if the first display 820a and the second display 820b complete the movement along the first direction from the front seat to the rear seat, the plurality of movable frames 840 can be deployed to form a perpendicular shape with the ceiling.

[0290] Additionally, in some embodiments, the tilt of the front seat 110 can be controlled as the first display 820a and the second display 820b move along a first direction toward the front seat. Specifically, the control unit 850 of the vehicle rear seat display device 800, in response to a first input signal, can generate a control signal for adjusting the seat angle of the front seat 110 and provide it to the vehicle system when the first display 820a and the second display 820b move together along the first direction. On the other hand, subsequently, a control signal for adjusting the seat angle of the front seat 110 can be generated and provided to the vehicle system so that the tilted front seat 110 returns to its previous state as the first display 820a and the second display 820b move again along the first direction toward the rear seat.

[0291] In another embodiment, the control unit 850 of the vehicle rear seat display device 800 can receive information about the vehicle's status and driving status via the communication unit 810, and determine whether to drive the second drive module 830b in response to a second input signal based on the received information. Specifically, the control unit 850 can determine whether to move the first display 820a and the second display 820b in a second direction that brings them closer together in response to the second input signal, based on the received vehicle status / driving status information. This is because when the first display 820a and the second display 820b move closer together while perpendicular to the ceiling, they obstruct the driver's rearview mirror's view, making it difficult to confirm vehicles behind. On the other hand, when the first display 820a and the second display 820b move in a second direction that moves them further apart, the operation can be performed without restriction.

[0292] As described above, the vehicle rear seat display device 800 of the present invention is implemented to move in different directions from each other, 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.

[0293] Figure 7a , Figure 7b , Figure 7c This is a diagram illustrating an example of the operation method when the first display 820a and the second display 820b are used as independent screens.

[0294] In its initial state, the first display 820a and the second display 820b can be in a horizontal position relative to the vehicle ceiling, together with a plurality of movable frames 840. In this state, if a rear-seat passenger needs to use at least one of the first display 820a and the second display 820b, or if a second input signal is received, the angle can be adjusted so that the plurality of movable frames 840 are perpendicular to the ceiling. Then, the image of at least one of the first display 820a and the second display 820b can be activated.

[0295] Reference Figure 7a The first display 820a and the second display 820b are arranged side by side in the rear seat of the front seat 110, separated by a predetermined separation distance L1. While the first display 820a and the second display 820b are separated by the separation distance L1, each can be used as an independent screen. Thus, the first display 820a can display a first image (screen1), and the second display 820b can display a second image (screen2) that is different from the first image.

[0296] Only one of the first display 820a and the second display 820b is active, while the unused other can remain in an inactive state.

[0297] Reference Figure 7b For example, if only the rear seat (left side) passenger wants to receive content services, the first display 820a can remain active, while the second display 820b can be deactivated. In this case, a support frame 802 supporting a plurality of fixed frames is arranged on the back of the separate first display 820a and second display 820b. Furthermore, one side of the support frame 802 is connected to a fixed frame 801 on the vehicle ceiling.

[0298] Figure 7b If a request to use the second display 820b occurs while the first display 820a is displaying the first screen 701, the second display 820b will also switch to an active state, thereby displaying the second screen 702. At this time, the second screen 702 can be any type of content screen unrelated to the first screen 701.

[0299] Figure 7cThis is an example diagram illustrating a scenario where image transmission occurs from an activated first display 820a to a deactivated second display 820b. For instance, while viewing a first image 701 on the first display 820a, if there is a need to transmit the same image to a passenger in the rear seat (right side), a portion of the second display 820b can output visual information 703 for receiving the image transmission. In this case, based on the response to the visual information 703, the second display 820b can be activated, and the same image as that on the first display 820a can be output to the second display 820b.

[0300] then, Figure 8a , 8b , Figure 8c , Figure 8d This is an example diagram illustrating a method for moving the first display 820a and the second display 820b closer to each other, and a screen control method based thereon.

[0301] If the first display 820a and the second display 820b receive the second input signal while maintaining a predetermined separation distance, they can move left and right closer to each other until one side of the first display 820a and the second display 820b touches each other.

[0302] For example, refer to Figure 8b Inside the vehicle 100, an input unit 870 receives inputs for controlling the movement of the first display 820a and the second display 820b of the rear seat display device 800. Figure 2 The input unit 870 can be positioned separately from the first display 820a and the second display 820b. For example, the input unit 870 can be arranged with consideration for the distance and height at which it can be operated without changing the arm length, seat position, and posture of the rear and front seat occupants of the vehicle. As some embodiments, the input unit 870 can be implemented as being arranged in the front and rear seats respectively or included in the menu items of the touch screen.

[0303] As an example, such as Figure 8b As shown, the input unit 870 can be implemented as including a plurality of buttons (e.g., "A, B, C, D, E") that move the first display 820a and the second display 820b in different directions or generate various input signals for screen control.

[0304] For example, button "A" can generate an input signal for operating in the initial state of the aforementioned first display 820a and second display 820b, and button "B" can generate an input signal for vertical tilt movement of the screen in the rear seat. Additionally, button "C" can generate a second input signal for moving the plurality of screens in a direction of approach or distance, and button "D" can generate an input signal for controlling the screen display of the plurality of screens in full-screen mode. Furthermore, button "E" can generate a first input signal including movement along the front seat (rear seat) and tilt movement of the plurality of screens.

[0305] The first display 820a and the second display 820b can move closer to each other in a second direction according to the second input signal. For this purpose, the control unit 850 can, when at least one of the first display 820a and the second display 820b is activated, control the screen to make the first display 820a and the second display 820b move closer to each other in the second direction in response to the received second input signal, so that the first display 820a and the second display 820b operate in full screen mode.

[0306] On the other hand, when the first display 820a and the second display 820b move close to each other and come into contact, they can be driven to maintain independent control and display the same application screen. As an example, see [reference needed]. Figure 8a and Figure 8b When input is applied to the aforementioned button "C" by the input unit 870, multiple screens can be displayed as a battle screen mode. Specifically, the first display 820a and the second display 820b can each display the execution screen of the same game application. Each screen is displayed in accordance with the field of view of the matched rider, and each rider can control the screen independently. 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.

[0307] Next, with the first display 820a and the second display 820b in contact, the plurality of screens can collectively display a full-screen image. For example, refer to... Figure 8b and Figure 8c When input is applied to the aforementioned button "D" from the input unit 870, it is possible to switch to a full-screen display of a single image across multiple screens. Thus, as... Figure 8c As shown, an image 903 is connected and displayed on a first display 820a and a second display 820b. At this time, due to the right border of the first display 820a and the left border of the second display 820b, a portion of the frames within an image 903 may be obscured or repeated.

[0308] Figure 8d When the first display 820a and the second display 820b operate in full-screen mode, the screen obstruction / disconnection caused by the bezel is eliminated, and the image is displayed. To this end, the bezel portion that contacts the first display 820a and the second display 820b is constructed in the shape of an LED strip, and the screen can be controlled so that the image output to the area above the bezel is obscured by the same image frame. Thus, during full-screen operation, the first display 820a and the second display 820b can operate to display a single image 904 without any gaps.

[0309] On the other hand, when the first display 820a and the second display 820b operate independently and display different images, upon receiving a request to operate in full screen, the control unit 850 can be configured to output the image to one of the displays in full screen to the entire first display 820a and the second display 820b according to a preset reference.

[0310] Here, the pre-set criteria can be determined based on at least one of the following: a full-screen request, a priority order of displayed content, a priority order of control by seat, a default setting state, and user settings. For example, if the selection is based on a priority order of displayed content, a certain screen information can be selectively displayed in full screen according to the content type and execution state corresponding to the first screen information and the second screen information displayed on the first display 820a and the second display 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 on the first display 820a can be selected as a full-screen image.

[0311] On the other hand, although not shown, during the period when the first display 820a and the second display 820b are in contact and operating in full-screen mode, the control unit 850 can control the screen to make the first display 820a and the second display 820b each operate as an independent screen again, based on the movement of the first display 820a and the second display 820b in a second direction away from each other in response to the received second input signal.

[0312] For example, the control unit 850 can operate to re-display or restore the previously displayed screen information on multiple screens to a previous state (e.g., deactivation state). Alternatively, for example, depending on the content type of the full screen (e.g., game content) and the execution state (e.g., battle mode in game content), the screen can be controlled to output the screen that was output as a single image to two screens simultaneously.

[0313] In addition, in the embodiment, the control unit 850 can control the screen to switch the other display back to a deactivated state when only one of the first display 820a and the second display 820b is activated, the first display 820a and the second display 820b move in a second direction toward each other in response to a received second input signal, and the first display 820a and the second display 820b move in a second direction away from each other in response to a subsequent second input signal.

[0314] As described above, the vehicle rear seat display device 800 of the present invention can perform multiple screens moving closer or further apart from each other, thereby controlling the content or screen state of the display to change adaptively, and thus providing a display mode service that meets the needs of rear seat passengers.

[0315] Next, Figure 9a and Figure 9b This is an example diagram illustrating the method of moving the first display 820a and the second display 820b to a position corresponding to the front seat of the vehicle, the screen control method based thereon, and the operation of the vehicle system.

[0316] The control unit 850 of the vehicle rear seat display device 800 can adjust the folding degree of the plurality of movable frames 840 in response to a first input signal, so that the first display 820a and the second display 820b form a predetermined angle between vertical and horizontal with the ceiling as a reference.

[0317] Specifically, the control unit 850 identifies the current positions of the first display 820a and the second display 820b based on the received first input signal, and determines whether to move the plurality of movable frames 840 towards the front seat or the rear seat based on the received first input signal. Furthermore, if the first display 820a and the second display 820b are not in a horizontal position relative to the fixed frame 801 of the ceiling, a folding action is performed to make the plurality of movable frames 840 horizontal with the fixed frame 801. Then, based on the determined direction, the drive of the first drive module 830a is controlled to move the folded plurality of movable frames 840 along the length direction of the fixed frame 801 of the ceiling. Driven by the motor included in the first drive module 830a, a driving force is transmitted to the plurality of movable frames 840, thereby causing the plurality of movable frames 840 to move along a first direction. Once the movement of the plurality of movable frames 840 is completed, an unfolding action is performed so that the plurality of movable frames 840 are perpendicular to the fixed frame 801 or the back of the plurality of movable frames 840 are at a specified angle (e.g., 60°) to the ceiling.

[0318] On the other hand, the control unit 850 of the vehicle rear seat display device 800 can control the display to show a first type of screen while the first display 820a and the second display 820b are in positions corresponding to the rear seats of the vehicle. Then, driven by the first drive module 830a, the first display 820a and the second display 820b move to positions corresponding to the front seats of the vehicle, changing the first type of screen to a second type of screen related to the vehicle's movement. Here, the first type of screen can be any type of content selected by the rear seat occupant. Additionally, the second type of screen can include, for example, the vehicle's navigation screen.

[0319] Figure 9a This illustrates an example of how the images displayed on the first display 820a and the second display 820b change after a plurality of movable frames 840 move from the rear seat to the front seat. For example, as... Figure 8d As shown, when the first display 820a and the second display 820b in the back seat display the movie image 904 in full screen and then move towards the front seat, the vehicle's driving image 905 can be displayed in full screen.

[0320] On the other hand, when the first display 820a and the second display 820b move toward the front seat or after the movement is completed, the vehicle rear seat display device 800 communicates with the vehicle system, thereby transmitting control signals from the vehicle rear seat display device 800 to the vehicle system to tilt the back of the front seat.

[0321] Reference Figure 9b If the first display 820a and the second display 820b move towards a position corresponding to the front seat according to the first input signal, the angle adjustment unit 860 performs an unfolding action of the plurality of frames 840. According to the unfolding action, the plurality of frames 840 rotate backward toward the vehicle's windshield, thereby adjusting so that the back of the plurality of frames 840 forms a predetermined angle with the vehicle's ceiling, for example, approximately 60 degrees. As described above, at the point in time when the first display 820a and the second display 820b move toward the front seat and pass through the intermediate position, or after the movement is completed, the seat back of the front seat 110 is tilted by the vehicle system, thereby forming a predetermined angle L4. Here, the predetermined angle L4 can be, for example, in the range of 20 to 30 degrees, and this value can vary depending on the current angle of the seat back and the sensing value of a sensor (e.g., a weight sensor) installed in the seat. Furthermore, if the front seat 110 is already in a tilted-back state, the tilting action can be omitted.

[0322] Figure 10 This is a flowchart illustrating the operation of the screen control and vehicle system when the first display 820a and the second display 820b move to a position corresponding to the front seat of the vehicle. Figure 10All or part of the actions shown can be related to Figure 6 The flowchart actions are combined and executed. Additionally, unless otherwise specified, Figure 10 The operation is premised on being executed by the control unit 850 (or processor 850) of the vehicle rear seat display device 800.

[0323] Reference Figure 10 In response to the first input signal, 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 display 820a and the second display 820b move together in the first direction (S25).

[0324] Specifically, when the first display 820a and the second display 820b move toward the front seat of the vehicle, the control unit 850 can provide the vehicle system with a first control signal for adjusting the tilt of the front seat 110. The vehicle system can control the backrest of the front seat 110 to tilt from vertical to approximately 20 to 30 degrees based on the first control signal.

[0325] Similarly, when the first display 820a and the second display 820b move toward the rear seat of the vehicle, the control unit 850 can provide a second control signal for adjusting the front seat 110 to pull forward and return to its previous state. The vehicle system can then act according to the second control signal to restore the backrest of the front seat 110 from a reclined state to an upright or initial set state.

[0326] On the other hand, although not described in detail, the rear seats of the vehicle can also be adjusted to tilt backward when the first display 820a and the second display 820b move toward the rear seats of the vehicle. In this case, when the first display 820a and the second display 820b move toward the front seats of the vehicle or fold horizontally with the fixed frame 801 of the ceiling, the tilted rear seat back can be returned to its initial state.

[0327] Independent of step S25 above, the vehicle rear seat display device 800 responds to the second input signal and automatically changes the display mode of the first display 820a and the second display 820b according to the movement of the first display 820a and the second display 820b closer to or further away from each other in the second direction (S45).

[0328] Specifically, as the first display 820a and the second display 820b move in a second direction that brings them closer to each other, the control unit 850 can control the screen to make the first display 820a and the second display 820b operate in a battle mode or a full-screen mode.

[0329] For example, when one of the first display 820a and the second display 820b is running a game application, if the first display 820a and the second display 820b move closer to each other and touch one side, the screens of each display 820a and the second display 820b can switch to a game battle mode screen. Alternatively, when one of the first display 820a and the second display 820b is displaying a movie screen, if the first display 820a and the second display 820b move closer to each other and touch one side, the movie screen can be displayed in full screen on both displays 820a and the second display 820b.

[0330] As described above, according to embodiments of the vehicle rear-seat display device and its operation method, as multiple screens located in the rear seats of the vehicle move toward or away from each other, the display mode of the screen changes, allowing them to be used as independent screens or multiple screens according to the needs of the rear-seat occupants. This further expands the user experience utilizing multiple screens. Furthermore, the multiple screens located in the rear seats of the vehicle are implemented such that they can move toward the front seats or back toward the rear seats, allowing front-seat occupants to use the rear-seat screens together when needed. This allows more occupants to share a limited number of displays, thereby expanding the user experience while maintaining a clean interior design for the vehicle. Moreover, the display mode automatically changes to match the audiovisual intentions of the vehicle occupants based on the movement of the multiple screens, and the seat tilting action is performed in parallel, enabling more comfortable audiovisual content viewing within the vehicle. Additionally, considering vehicle driving safety, the multiple screens are restricted from moving toward the front seats while the vehicle is in motion, and the combination of multiple screens in the rear seats is limited during manual driving, thus simultaneously meeting the needs of the occupants and ensuring driving safety.

[0331] The aforementioned invention can be implemented using computer-readable code stored in a medium containing a program. Computer-readable media include all types of storage devices storing data that can be read by a computer system. Examples of computer-readable media include HDDs (Hard Disk Drives), SSDs (Solid State Disks), SDDs (Silicon Disk Drives), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc., and can also be implemented in the form of a carrier wave (e.g., internet-based transmission). Additionally, the computer may also include a controller / processor for the vehicle display device 800. Therefore, the detailed description above should not be construed as limiting in all respects, but rather as exemplary. The scope of this specification should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of this specification should fall within the scope of this invention.
