Description

Vehicle display device and its operating method

[0001] The present invention relates to a vehicle display device, and more specifically, to a vehicle display device implemented so as to form a plurality of screens using graphics output from one display module.

[0002] A vehicle is a device that allows the user to move in the desired direction. A representative example is an automobile.

[0003] Meanwhile, various sensors and electronic devices are being installed in vehicles to enhance the convenience of users. In particular, research is actively underway on Advanced Driver Assistance Systems (ADAS) to enhance user convenience. Furthermore, development of autonomous vehicles (AVs) is also actively underway.

[0004] Autonomous driving refers to a system that enables a vehicle to make its own decisions and drive accordingly. Autonomous driving can be categorized into stages ranging from non-automation to full automation, depending on the degree to which the system participates in driving and the degree to which the driver controls the vehicle.

[0005] Autonomous driving has transformed the perception of vehicles as spaces for dwelling, rather than simply a means of transportation. Furthermore, the trend toward installing larger displays in vehicles has become widespread, allowing drivers to freely enjoy a variety of infotainment options. Furthermore, research and development are being conducted to provide a more diverse user experience when using these displays.

[0006] The present invention aims to solve the above-mentioned problems and other problems.

[0012] To this end, the vehicle display device according to an embodiment of the present invention can adjust the viewing angle for a plurality of screens generated by refracting or reflecting graphics projected onto one display through different reflective modules.

[0013] Specifically, a vehicle display device according to an embodiment of the present invention includes: a housing having a recessed inner space formed therein; a display disposed on an upper portion of the inner space of the housing; a communication module for receiving status information from a vehicle; a first reflective module coupled to one side of the display in the inner space and arranged so that graphics emitted from a first area of ​​the display are refracted to form a first screen area; a second reflective module coupled to one side of the first reflective module in the inner space and arranged so that graphics emitted from a second area of ​​the display are reflected to form a second screen area; a viewing angle adjustment module disposed corresponding to a front surface of the display and adjusting a viewing angle so that light emitted from the display is emitted within a predetermined angular range; and a processor electrically coupled to the display, the first and second reflective modules, and the viewing angle adjustment module to control their respective operations.

[0194] FIG. 3 is an exemplary drawing showing a vehicle display device (800) installed and operated in a vehicle according to the present invention.

[0195] The vehicle display device (800) may be installed to correspond to the dashboard of the driver's seat of the vehicle (100) or may be installed in a rectangular shape extending from the dashboard of the driver's seat to the passenger seat.

[0196] A vehicle display device (800) includes a housing (801) having a recessed inner space formed therein, and a display may be placed on one side of the inner space of the housing (801). For example, the display of the vehicle display device (800) may be placed on the upper part of the inner space of the housing (801) with the front of the display facing downward.

[0197] The housing (801) is implemented to have an inner space recessed inward, thereby forming a natural darkroom space. Accordingly, the real and virtual images displayed on the first and second screen areas formed by the first and second reflective modules (820, 840) described below can be displayed more clearly.

[0198] The inner space of the housing (801) may be implemented in a shielded manner, while the outer space facing the driver's seat may be implemented in an open manner. In addition, the inner space of the housing (801) may be formed so that the space becomes narrower as it deepens toward the inside, and becomes wider as it goes toward the outside.

[0199] The housing (801) may have multiple screen areas formed in its inner space according to the operation of the display. In an embodiment, some of the multiple screen areas may be formed to extend beyond the inner space of the housing (801).

[0200] The plurality of screen areas may include a first screen area (821) formed above the inner space of the housing (801) and a second screen area (841) formed below the first screen area (821).

[0201] The first screen area (821) is a prism screen area formed by refracting graphics displayed in a portion of the display through a prism, thereby allowing a real image to be displayed. Furthermore, the second screen area (841) is a floating screen area formed by reflecting graphics displayed in another portion of the display through a 3D plate, thereby allowing a virtual image to be output.

[0202] In the prism screen area, a real image, for example, which is formed by polarized light refracted through a prism and reflected through a mirror, may be displayed on the prism. In addition, in the floating screen area, a 3D virtual image (AR) formed based on graphic light of a display reflected through a 3D plate, for example, may be displayed within the inner space of the recessed housing (801), or at least a portion of the image may be displayed outside the inner space.

In addition, the vehicle display device (800) may communicate with a vehicle (100) through the communication unit (830). In addition, the vehicle display device (800) may be implemented to form a first screen area (821) / second screen area (841) / multi-screen area (821, 841) through the first reflection module (820) and / or the second reflection module (840).

[0207] The housing (801) constitutes a frame of the vehicle display device (800) and is formed to include an inner space recessed therein.

[0208] The display (810) may be placed on one side of the inner space of the housing (801), for example, on the upper part of the inner space. At this time, the back surface of the display (810) may be coupled to the ceiling of the inner space of the housing (801), and the front surface of the display (810) may be placed facing the floor.

[0209] The display (810) may be arranged to be tilted at a predetermined angle so as not to be parallel to the floor. To this end, the ceiling of the inner space of the housing (801) may be formed to be tilted at a predetermined angle relative to the floor. In this way, by forming the display (810) to be tilted at a predetermined angle relative to the floor, the floating effect of the 3D AR image displayed on the second screen area formed by the second reflective module (840) is further maximized.

[0210] The communication unit (830) can receive data related to the vehicle status and driving from a vehicle (100) in which a vehicle display device (800) is installed. In addition, the communication unit (830) can transmit data related to the operating status and driving of the vehicle display device (800) to the vehicle (100). To this end, the communication unit (830) may be implemented to include a transmission module and a reception module, or a transceiver capable of both transmission and reception.

[0211] The first reflective module (820) may be arranged to be combined with one side of the display (810) in the inner space of the housing (801). The first reflective module (820) may be arranged so that light of graphics emitted from the first area of ​​the display (810) is refracted to form a first screen area. The first screen area refers to a prism area in which a real image of linearly polarized light corresponding to the graphics of the display (810) refracted through the prism is displayed. Hereinafter, the "first screen area" may be referred to as a 'prism area', a 'prism display', a 'prism screen', or a 'prism screen area'.

[0212] The first reflective module (820) may include a prism and a reflector to form a first screen area. The first screen area is formed above the second screen area described below, so that graphics emitted from the first area of ​​the display (810) can be output as real images.

[0213] The second reflective module (840) may be arranged to be combined with one side of the first reflective module (820) in the inner space of the housing (801). The second reflective module (840) may be arranged to reflect light of graphics emitted from the second area of ​​the display (810) to form a second screen area. The second screen area refers to an AR floating area in which a virtual (AR) image is displayed in the inner space of the housing (801) by being connected to the first screen area. Hereinafter, the “second screen area” may be referred to as a “floating area,” a “floating screen,” a “floating display,” a “floating screen area,” a “virtual screen area,” or an “AR floating area.”

[0214] The second reflective module (840) may include a 3D plate and a reflector to form a second screen area. In this case, the second screen area is formed below the first screen area, so that graphics emitted from the second area of ​​the display (810) can be output as a virtual image, i.e., a 3D AR image.

[0215] The processor (850) controls the overall operation of the display (810), the first reflective module (820), and the second reflective module (840). The processor (850) may be placed on the inner surface of the inner space of the housing (801) or on the outer surface of the back surface of the housing (801).

[0216] The processor (850) can control whether the display (810) is driven when the vehicle is started or based on a request. When the display (810) is driven, the processor (850) can control the operation of the first reflection module (820) and / or the second reflection module (840), so that the graphics displayed on the display (810) appear as real and / or virtual images through the first screen area and / or the second screen area.

[0217] When the display (810) is driven, the processor (850) can control the operation of at least one of the first and second reflective modules (820, 840) according to set conditions, thereby changing whether the first and second screen areas are activated. Accordingly, the occupants of the vehicle (100) can check the graphics displayed through the display (810) in the first screen area / second screen area / multi-screen area.

[0218] The processor (850) can control the operation of the rotation control unit (860) to change the position of the second screen area formed through the second reflection module (840). Meanwhile, the rotation control unit (860) can also be implemented as a function of the processor (850).

[0219] The rotation control unit (860) can control the rotation of the second reflection module (840) so that the reflection angle or optical path length formed by the second reflection module (840) with the display (810) is changed. To this end, the second reflection module (840) can be implemented to be rotatable by being coupled to a rotation driving means on one side of the rotation control unit (860).

[0220] As the rotation of the second reflection module (840) is adjusted by the operation of the rotation control unit (860), the position of the second screen area formed through the second reflection module (840) can be changed. Accordingly, the 3D virtual image displayed on the second screen area can move back and forth.

[0221] The rotation control unit (860) may be configured to include a coupling means for coupling with the second reflection module (860), a rotation means for rotating the second reflection module (860), and a support means for supporting the plate when rotating the second reflection module (860).

[0222] The sensor (870) may include a sensor for detecting input to the display (810) and a sensor for detecting (hovering) input to the first and second screen areas. In addition, the sensor (870) may further include a camera sensor, an IR sensor, an IMS sensor, etc. for recognizing the subject performing the input or monitoring the status of the driver / passenger.

[0223] In some examples, the sensor (870) may include a vehicle camera sensor, an IR sensor, or an IMS sensor. The vehicle display device (800) may recognize the passenger's field of view through the sensor (870) and transmit information about the same to the processor (850). Then, the processor (850) may adjust the position at which the second screen area is formed by changing the position of the second reflective module (840) based on the passenger's field of view.

[0224] Meanwhile, the vehicle display device (800) may further include a front cover (802). In this case, the front cover (802) may be shielded so that the inner space of the housing (801) is not visible when the display (810) is not operated, and may be operated so that the inner space of the housing (801) is exposed when the display (810) is operated.

[0225] In this way, the vehicle display device (800) according to an embodiment of the present invention can selectively or simultaneously implement composite content of virtual and real images with one display module by refracting part of the graphics emitted from one display (810) placed on one side of the internal space of the housing (801) through the first reflection module and reflecting part of the graphics through the second reflection module.

[0226] FIG. 5 is a side cross-sectional view of a vehicle display device (800) according to the present invention. Specifically, FIG. 5 is a side view of a "package" configuration for outputting graphics displayed on a single display positioned above the vehicle display device (800) through a prism screen and a floating screen.

[0227] A display (810) tilted to form a predetermined angle with the floor may be placed on the upper part of the package. That is, the display (810) may be placed on the upper part in a state of being tilted at a predetermined angle so as not to be parallel to the floor. Accordingly, the floating effect of a 3D virtual image displayed on a floating area formed through a second reflective module (840) described later may be expressed more three-dimensionally and prominently. In addition, since the front of the display (810) is placed on the upper part so that it faces the floor, the graphic light emitted on the front of the display (810) when the display (810) is driven is emitted in a vertical direction.

[0228] A processor (850), for example, a PCB, for controlling the operation of a vehicle display device (800) is disposed on the back surface of the package. The processor (850) controls the operation of the display (810) and the activation and operation of the first and second reflective modules (820, 840). The processor (850) is electrically coupled to one side of the display (810) and may be disposed so as to form a vertical line with the display (810) disposed above.

[0229] The first reflective module (820) can operate to display a real-world image on the prism by refracting graphic light emitted to a portion of the display (810) through a prism vertically coupled to one side of the display (810).

[0230] The prism of the first reflection module (820) is a projection body made by cutting a transparent, transmissive material at a precise angle and plane, and disperses the light of the graphic output to the first area of ​​the display (810) to change the optical path. The prism of the first reflection module (820) is arranged to form a perpendicular shape to the display (810) and may have, for example, a triangular prism shape. Accordingly, the light of the graphic output to the first area of ​​the display (810) is refracted to form a first screen area (or prism area) (821) on the surface of the prism that forms a right angle to the display (810). In an embodiment, depending on the number of reflection mirrors coupled to the prism, the image of the graphic output to the first area of ​​the display (810) is inverted or displayed in the same shape on the first screen area.

[0231] The second reflective module (840) is coupled to one side of the first reflective module (820) and includes a 3D plate positioned to form a predetermined angle with the display (810). The 3D plate, for example, a 3D hologram plate, can reflect light of graphics projected to another area of ​​the display (810), for example, the second area, to display a virtual image, i.e., a 3D virtual image, at a location corresponding to the passenger's viewing angle.

[0232] At this time, the first screen area formed through the first reflection module (820) and the second screen area formed through the second reflection module (840) have different depths. Specifically, the first screen area (821) is formed on the front surface of the prism of the first reflection module (820), while the second screen area (841) is formed in a 3D space formed by reflection through the 3D plate of the second reflection module (840). At this time, a part of the second screen area may be located on the same plane as the first screen area.

[0233] Meanwhile, the package may be placed within a housing (801, FIG. 4) including a recessed inner space. With this housing (801) structure, the second reflective module (840) reflects the light of the graphic emitted from the display (810) through the 3D hologram plate and forms an image at the bottom, thereby naturally blocking external light.

[0234] Meanwhile, although not shown, the package may further include a light absorbing portion for absorbing light of graphics emitted from the display (810) and a back plate coupled to the back surface of the 3D plate of the second reflective module (840).

[0235] At this time, the material of the back plate may be a UTG (ultra-thin glass) plate material, and may perform the function of supporting the 3D hologram plate on the back.

[0236] In addition, the light absorption unit is arranged to form a dark room on the left and right sides of the housing (801) so as to absorb light scattered by the graphics emitted from the display (810). The light absorption unit reduces the reflected brightness of the light from the graphics, thereby improving the contrast of the 3D virtual image displayed on the second screen area (841).

[0237] The processor (850) of the package can control the rotation of the 3D plate of the second reflection module (840) to change the angle formed between the plate and the display (810). Based on the change in the angle formed between the 3D plate of the second reflection module (840) and the display (810), the position of the 3D virtual image displayed on the second screen area (841) can be changed. To this end, one side of the second reflection module (840) can be coupled with a rotation control unit (860, FIG. 4) and driven to rotate the 3D plate of the second reflection module (840) based on a signal transmitted from the processor (850).

[0238] In some embodiments, the package may have a rotatable structure or include a drive cover so that the configuration of the package is shielded when the display (810) is not operated, and at least a portion of the first and second screen areas (821, 841) formed by the first and second reflective modules (820, 840) is exposed when the display (810) is operated.

[0239] Continuing with reference to FIG. 5, the package may be implemented such that it is placed within a housing (801) having a recessed inner space, such that a floating area formed through the second reflective module (840) is displayed within the recessed inner space.

[0240] Additionally, as described above, a portion of the floating area whose position has changed as the 3D plate of the second reflective module (840) rotates may be implemented to be displayed beyond the recessed inner space. Accordingly, a portion of the 3D floating content displayed in the floating area may be imaged beyond the recessed inner space of the housing (801).

[0241] The vehicle display device (800) reflects / refracts graphics emitted from the display (810) positioned at the top through the first and second reflective modules (820, 840), which are prisms and 3D plates, to form 3D virtual and real images in the prism area (821) and the floating area (841), thereby enabling real and virtual images to be implemented independently or simultaneously with a single display.

[0242] The light of the graphic emitted from the display (810) may be refracted through one or more lenses and prisms to form an eye box. To this end, an incident optical module for forming a curvature and an optical path may be further included. For example, the lens and prism may be arranged at a predetermined angle (e.g., a right angle) with the display so as to have a curvature and an optical path for forming an eye box for the graphic displayed in the first area of ​​the display (810).

[0243] Additionally, the light of the graphic emitted from the display (810) may be reflected through the 3D plate and the reflective mirror to form an eye box for displaying a virtual image. At this time, a combiner for compensating for chromatic aberration and focal length may be combined. The combiner may include a 3D plate, for example, a 3D hologram plate, and a reflective mirror for reflecting the refracted light of the graphic emitted through the prism.

[0244] At this time, the reflective mirror can be configured in the form of a flat plate or film. The reflective surface of the reflective mirror is formed on the front surface of the 3D plate facing the user's eyes, thereby compensating for chromatic aberration and focal length. In addition, in the present invention, since the graphic light of the display (810) positioned on the upper part of the package is refracted through a prism or directly irradiated onto the 3D plate, chromatic aberration due to wavelength separation hardly occurs.

[0245] FIG. 6 is a side view of a prism display area (821) and a floating display area (841) formed according to the operation of a display device (800).

[0246] As illustrated in FIG. 6, the prism display area (821) may be formed on the upper portion of the recessed inner space of the housing (801), and the floating display area (841) may be formed on the lower portion of the recessed inner space of the housing (801).

[0247] The size of the floating display area (841) may be formed to be larger than the size of the prism display area (821). A real image may be displayed in the prism display area (821), and a virtual image with depth, i.e., a 3D AR image, may be displayed in the floating display area (841).

[0248] The prism display area (821) and the floating display area (841) can be used selectively or driven simultaneously.

[0249] To this end, the processor (850) of the vehicle display device (800) can change whether the first and second screen areas, i.e., the prism display area (821) and the floating display area (841), are activated by controlling the operation of at least one of the first and second reflective modules (820, 840) according to preset conditions when the display (810) is driven.

[0250] At this time, the preset conditions are related to the driving status of the vehicle (100) in which the vehicle display device (800) is installed. For example, the preset conditions may be matched to various situations in which the driving status of the vehicle requires a warning / alarm.

[0251] The processor (850) can activate the first reflection module (820) while the vehicle is in the first driving state based on information related to the vehicle driving state received through the communication unit (830) to display the vehicle driving state in the prism display area (821).

[0252] Here, the first driving state refers to a normal driving state after the vehicle is started, and is a general driving situation that does not require a warning / alarm.

[0253] Continuing, when the vehicle changes from the first driving state to the second driving state according to information related to the vehicle driving state received through the communication unit (830), both the first and second reflective modules (820, 840) can be activated to control the first and second reflective modules (820, 840) to display the vehicle driving state together in the prism display area (821) and the AR floating display area (840).

[0254] Here, the second driving state refers to a driving situation requiring a warning / alarm while the vehicle is driving. For example, the processor (850) may determine that the second driving state is in effect when a warning / alarm is required due to a violation of the speed limit, a sharp curve ahead, or the appearance of an object around the vehicle. Once the situation is resolved, the processor may determine that the vehicle has transitioned to the first driving state.

[0255] In addition, according to information related to the vehicle driving state received through the communication unit (830), the second reflection module (840) can be activated while the vehicle (100) is in the third driving state to display an AR virtual image in the AR floating display area (840) and control to display a graphic object related to the AR virtual image in the prism display area (821).

[0256] Here, the third driving state may mean a state in which the entertainment function is executed while the vehicle is stopped.

[0257] In another embodiment, the processor (850) of the vehicle display device (800) may determine to display either one of the prism display area (821) and the AR floating display area (840), or both, depending on the type of content output to the display (810). For example, a content type related to a vehicle status may be displayed in the prism display area (821), and an entertainment content type may be displayed in the AR floating display area (840).

[0258] In another embodiment, the processor (850) of the vehicle display device (800) may decide to display either the prism display area (821) or the AR floating display area (840), or both, based on a user's input / request.

[0259] As described above, the vehicle display device (800) according to an embodiment of the present invention can selectively provide a usage environment of multiple displays with one display.

[0260] FIG. 7 is an exemplary drawing for explaining multiple display areas according to the display mode of the vehicle display device (800).

[0261] The vehicle display device (800) can operate in a 'prism display mode' that displays a real image in a prism screen area, a 'floating display mode' that displays a virtual image in a floating screen area, or a 'multi-display mode' that displays a real image and a virtual image simultaneously in the prism screen area and the floating screen area, depending on the set conditions.

[0262] Here, the set conditions may be related to the driving status of the vehicle, as described above, or may be associated with the type of content to be captured, or may correspond to user input / request.

[0263] Meanwhile, the vehicle display device (800) can control the floating screen area (841) formed through the second reflective module (840) to be displayed at positions corresponding to the driver's seat and the passenger's seat, respectively, in the recessed inner space of the housing (801).

[0264] Specifically, referring to FIG. 7, the floating screen area (841) can be divided into a first floating area (841a) positioned to correspond to the driver's seat, a third floating area (841c) positioned to correspond to the passenger seat, and a second floating area (841b) positioned to correspond between the driver's seat and the passenger seat.

[0265] The first floating area (841a) may be an area used by the driver's seat passenger, and the third floating area (841c) may be a display area used by the passenger in the passenger seat. Additionally, the second floating area (841b) may be a display area shared by the driver's seat and passenger in the passenger seat.

[0266] The first floating area (841a) displays a 3D AR image that is floated to correspond to the viewing angle of the driver's seat passenger. Furthermore, the third floating area (841c) displays a 3D AR image that is floated to correspond to the viewing angle of the passenger in the passenger seat. Furthermore, the second floating area (841b) displays a 3D AR image that is floated to correspond to a preset viewing angle, for example, a viewing angle set to correspond to the driver's seat or the passenger seat.

[0267] The contents displayed in the first to third floating areas (841a, 841b, 841c) can be independently controlled for display.

[0268] Additionally, the vehicle can operate in SPM (Switchable Privacy Mode, SPM) mode so that the first floating area (841a) is not visible from the passenger seat, and the content displayed in the third floating area (841c) is not visible from the driver's seat. At this time, 3D content can be displayed in the second floating area (841b) at a viewing angle that can be viewed from both the driver's seat and the passenger seat.

[0269] FIG. 8 is a side view of a vehicle display device (800) disposed in a cluster / CID area of ​​a vehicle (100) according to the present invention. As illustrated in FIG. 8, a housing (801) of the vehicle display device may be disposed at a position corresponding to the dashboard of the driver's seat. The housing (801) may be formed to have an inner space recessed inwardly, for example, such that the basic volume is approximately 23 liters.

[0270] Although not shown in detail, when the vehicle display device (800) is driven, a prism display area (821) in which a real image is displayed and a floating display area (841) in which a virtual image, i.e. a 3D AR image, is displayed are formed in the inner space of the housing (801) open toward the passenger's visual angle, and can be provided to the user's eye box.

[0271] When the vehicle display device (800) is not in operation, the housing (801) can be rotated or shielded through the front cover so that the inner space of the housing (801) is hidden.

[0272] The vehicle display device (800) can selectively activate a prism display area (821) and a floating display area (841) to provide graphics illuminated on a display (810) positioned on the upper portion of the inner space of the housing (801) to a user's viewing angle.

[0273] To this end, the vehicle display device (800) can be controlled so that graphics emitted in the first area of ​​the display (810) are refracted through a prism and then a real image is displayed on the surface of the prism.

[0274] In addition, the vehicle display device (800) can be controlled to display a 3D AR image in the inner space of the housing (801) that matches the user's eye level after the graphic emitted in the second area of ​​the display (810) is refracted through a prism, reflected through a 3D plate, and then passes through a reflective polarizing plate and / or an absorbent polarizing plate.

[0275] Below, FIG. 9 is an exemplary flowchart for explaining the operation method of a vehicle display device (800) according to the present invention.

[0276] Referring to FIG. 9, the operating method of a vehicle display device (800) according to an embodiment of the present invention begins with a step of driving a display positioned on one side of the inner space of a housing (801, FIG. 4) (S10). As the display (810) is driven, graphics are emitted on the front surface.

[0277] To this end, the display (810) of the vehicle display device (800) may be formed with a structure in which the front is positioned on the inner upper part of the inner space of the housing (801) with the front facing the ground, but has an inclination that is not parallel to the ground.

[0278] In this way, by placing the display (810) on the inner upper part of the inner space of the housing (801), the light of the emitted graphic can have a curvature and an optical path for forming an eye box. Accordingly, an optical path is formed so that the light of the graphic emitted by the display (810) is directed toward the 3D plate of the second reflective module (840) without being dispersed.

[0279] In addition, since the display (810) placed on the top is formed in a structure that is not parallel to the ground but rather inclined, the floating effect of the 3D AR image appearing in the floating display area (841) formed through the second reflective module (840) is maximized.

[0280] Continuing, the vehicle display device (800) can operate so that the graphics emitted in the first area of ​​the display (810) are refracted through the first reflective module (820) to form a first screen area (S20).

[0281] In addition, the vehicle display device (800) can operate so that graphics emitted from the second area of ​​the display (810) are reflected through the second reflection module (840) to form a second screen area (S30).

[0282] The formation of the first and second screen areas in this way can be said to mean that the graphics emitted by the display (810) are ready to be imaged in either the first or second screen areas.

[0283] In this way, when the preparation for focusing on one or all of the plurality of screen areas is completed, the vehicle display device (800) can control at least one of the first and second screen areas formed through the first and second reflective modules (820, 840) to be activated based on whether the set conditions are satisfied (S40).

[0284] Specifically, for example, a first screen area formed through a first reflective module (820) may be activated to display only a vehicle driving status, so that a real-world image may be displayed on the surface of the prism. In addition, for example, a second screen area formed through a second reflective module (840) may be activated to display a warning / alarm during vehicle driving or to provide guidance on a dangerous situation, so that a floating 3D AR image may be displayed in the recessed inner space of the housing (801). At this time, the recessed inner space of the housing (801) with its side shielded naturally provides a darkroom effect, so that the floating 3D AR image may be displayed more clearly.

[0285] Meanwhile, FIGS. 10, 11, and 12 are various structural examples of a vehicle display device (100) for implementing multiple display modes with one display according to an embodiment of the present invention.

[0286] FIG. 10 is a basic structure of a housing (801) of a vehicle display device (800), in which a display (810) is arranged on the upper portion of a recessed inner space of the housing (801), and a processor (850) may be included on the back surface of the inner space. In addition, a first reflective module (820) coupled to one side of the display (810) and including a prism is arranged to be perpendicular to the display (810) in the same vertical direction in which light is emitted from the display (810). In addition, a second reflective module (840) coupled to one side of the first reflective module (820) and reflecting light refracted through the prism of the first reflective module (820) may be arranged to form a predetermined angle with the display (810). At this time, the second reflective module (840) may be formed by including a 3D hologram plate and a reflective mirror (not shown) that are placed in the inner space of the housing (801) and formed to face the front of the display (810).

[0287] In an embodiment, the processor (850) can control the prism of the first reflection module (820) to refract linear polarization corresponding to graphics emitted in the first area of ​​the display (810) to form a first screen area while the first reflection module (820) is activated.

[0288] In addition, the processor (850) can control the 3D plate of the second reflection module (840) to reflect the linear polarization refracted through the graphic or prism emitted to the second area of ​​the display (810) while the second reflection module (840) is activated to form a second screen area that displays a 3D virtual (AR) image.

[0289] The first screen area formed through the first reflective module (820) is formed on top of the second screen area formed through the second reflective module (840) and extends to the first area of ​​the display (810).

[0290] In addition, the second screen area formed through the second reflection module (840) is formed below the first screen area formed through the first reflection module (820), and the 3D AR content displayed in the second screen area may be formed only within the inner space of the housing (801) or may be formed so that a portion thereof extends beyond the inner space.

[0291] FIG. 11(a) is an exemplary structure in which only the first screen area formed through the prism of the first reflective module (820) is used when the vehicle display device (800) is driven by the display (810). In FIG. 11(a), the housing (801') is folded or rotated so that the 3D hologram plate is parallel to the display (810), so that the volume of the housing (801') can be minimized. This housing (801') structure can be called a minimum slim package, and the graphic emitted by the display (810) is refracted through the prism and displayed as a real image on the front surface. For example, when the 3D hologram plate of the second reflective module rotates so that the inner space of the housing (801') is reduced to a minimum, the volume of the minimum slim package can be changed to 9 liters.

[0292] Meanwhile, (b) of FIG. 11 shows a state in which both the first and second reflective modules (820, 840) are operated and the corresponding first and second screen areas are activated in accordance with the operation of the display (810) of the vehicle display device (800). At this time, the processor (850) may be arranged on the outer rear surface of the housing (801") so as to be coupled to one side of the display (810).

[0293] Additionally, according to an embodiment, a UTG plate may be combined on the front side of the 3D plate of the second reflective module (840) to form an optical path of the eye box. Additionally, although not shown, a light absorption plate may be further provided adjacent to the 3D plate of the second reflective module (840) to further absorb linearly polarized light not reflected through the 3D plate.

[0294] Continuing with reference to FIG. 12, the package of the vehicle display device (800) can be implemented with a slimmer structure by being formed integrally with the air duct of the driver's seat of the vehicle (100) on the dashboard. In this way, when modularized together with the vehicle's air purifier, the package and housing can be implemented to have a volume of 11 liters, which is slightly larger than the volume of the minimum slim package described above.

[0295] In the above, examples and structures of a vehicle display device (800) according to an embodiment of the present invention that displays graphics of different types in multiple display areas through one display have been examined.

[0296] Hereinafter, with reference to FIG. 13, a method for changing the position of an AR image displayed in a floating display area in a vehicle display device (800) according to the present invention will be specifically described.

[0297] A real image can be displayed on the surface of a prism in the first screen area formed through the first reflection module (820), and a 3D virtual (AR) image with depth can be displayed in the second screen area formed through the second reflection module (840).

[0298] In an embodiment of the present invention, a 3D virtual (AR) image displayed in the second screen area can be displayed while moving in the x-axis, y-axis, and z-axis directions within the inner space of the housing (801). To this end, the 3D hologram plate of the second reflection module (840) is implemented to be rotatable so that the angle formed between it and the display (810) can be adjusted.

[0299] Specifically, as illustrated in FIG. 13, the first reflective module (820) is fixed to one side of the display (810), and the second reflective module (840) is arranged in a rotatable structure in the inner space of the housing (801). One side of the second reflective module (840) is fixed adjacent to the first reflective module (820), and is formed so that the distance from the display (810) increases from the one side to the other side. In addition, the second reflective module (840) is formed so that the angle between it and the facing display (810) can be changed according to the operation of the rotation control unit (860).

[0300] The processor (850) of the vehicle display device (800) can transmit a signal to the rotation control unit (860) to adjust the rotation of the second reflection module (840) so that the angle between the second reflection module (840) and the display (810) is changed.

[0301] The rotation control unit (860) may include a coupling means coupled to one side of the 3D plate of the second reflection module (840), a driving means providing a driving force for rotation to the 3D plate, and a support means supporting the 3D plate while the 3D plate rotates.

[0302] When the rotation control unit (860) operates according to the driving signal transmitted from the processor (850), the 3D plate of the second reflection module (840) can rotate by a set angle in a clockwise or counterclockwise direction based on the information included in the driving signal.

[0303] This is an exemplary drawing showing the basic position of the second reflective module (840) in the inner space of the housing (801) of Fig. 13 (a). When the 3D plate of the second reflective module (840) is placed in a predetermined basic position, the second screen area (841) where 3D AR content is displayed can be displayed, for example, at the entrance of the inner space of the housing (801).

[0304] In an embodiment, the processor (850) can control the rotation of the second reflection module (840) through the rotation control unit (860) to change the angle between the display (810) and the 3D plate, and based on this, control the position of the second screen area (841) where 3D AR content is displayed to move forward and backward based on the inner space of the housing (801).

[0305] Figure 13 (b) is an example in which the 3D plate of the second reflective module (840) is rotated clockwise by a certain angle from the basic position so that the angle between the display (810) and the 3D plate becomes larger.

[0306] As the size of the angle between the 3D plate of the display (810) and the second reflective module (840) increases, the position of the second screen area (841) formed through the second reflective module (840), i.e., the floating display area, protrudes forward. Accordingly, at least a portion of the 3D AR image displayed on the second screen area (841) may be displayed outside the inner space of the housing (801).

[0307] Meanwhile, (c) of FIG. 13 is an example in which the 3D plate of the second reflective module (840) is rotated counterclockwise by a certain angle from the basic position so that the angle between the display (810) and the 3D plate becomes smaller.

[0308] As the size of the angle between the display (810) and the 3D plate of the second reflective module (840) decreases, the position of the second screen area (841) formed through the second reflective module (840), i.e., the floating display area, is pushed rearward and displayed. Accordingly, the 3D AR image displayed on the second screen area (841) can be displayed further inside the inner space of the housing (801).

[0309] Figure 13 (d) illustrates a 3D AR image (1301) displayed on the second screen area, i.e., the floating display area (841), moving forward and backward (1302) in the inner space of the housing (801) according to the rotation of the 3D plate of the second reflective module (840). At this time, the graphics displayed on the first screen area, i.e., the prism display area, formed through the first reflective module (820) are continuously displayed on the same plane.

[0310] In this way, movement of the 3D AR image according to a change in the position of the 3D plate of the second reflection module (840) can be performed based on various conditions.

[0311] In an embodiment, the processor (850) of the vehicle display device (800) may adjust the rotation of the second reflective module (840) so that the position of the second screen area is variable based on the view angle information (e.g., eye box / eye level) of the passenger detected by the IMS (internal camera) or DMS sensor of the vehicle (100) received from the vehicle (100). To this end, the processor (850) may calculate the refraction, curvature, and optical path matching the view angle information of the passenger detected through the IMS / DMS sensor, and adjust the position of the 3D plate of the second reflective module (840) when the display (810) is driven.

[0312] In addition, in the embodiment, the processor (850) of the vehicle display device (800) may activate the first and second screen areas formed through the first and second reflective modules (820, 840) when the display (810) is driven. Next, the processor (850) may display a real first graphic image on the first screen area (821), i.e., the prism display area, and may adjust the rotation of the second reflective module (840) so that the position of the floating display area adaptively changes based on the movement of the virtual second graphic image displayed on the second screen area (841), i.e., the floating display area.

[0313] For example, if the 3D AR image displayed on the floating display area is a 3D content type implemented to move back and forth, the 3D plate of the second reflective module (840) can rotate to correspond to such a movement pattern. Accordingly, the 3D virtual (AR) image can operate to move back and forth based on the recessed inner space of the housing (801), as shown in (d) of FIG. 13. To this end, the 3D plate of the second reflective module (840) can be driven to rotate according to a pattern preset for each content.

[0314] Also, for example, in the case of content where it is effective to display a 3D (AR) virtual image so that it protrudes toward the driver, the position may be changed in a direction where the angle between the 3D plate of the second reflective module (840) and the display (810) increases. Similarly, in the case of content where it is effective to display a 3D virtual (AR) image so that it is retracted into the housing (801), the position may be changed in a direction where the angle between the 3D plate of the second reflective module (840) and the display (810) decreases. For example, the 3D plate of the second reflective module (840) may rotate clockwise / counterclockwise to exhibit the effect of the 3D virtual (AR) image zooming in / out. Alternatively, the 3D plate of the second reflective module (840) may remain fixed and the housing including the package may rotate in a specific direction to exhibit the same / similar effect.

[0315] Meanwhile, the aforementioned package may be formed to have a structure that can rotate together with the dashboard of the vehicle (100). In this case, the recessed inner space of the housing (801) may be exposed or shielded in response to the rotation of the package. As another example, a front cover may be further provided to shield the recessed inner space of the housing (801).

[0316] Hereinafter, a method for adjusting a user's viewing angle for a plurality of screens, i.e., a prism region and a floating region, formed by reflection / refracting from a display (810) in a vehicle display device (800) according to an embodiment of the present invention will be specifically examined.

[0317] As described with reference to FIG. 7, the floating area (841) can be divided into multiple sub-areas. Specifically, it can be subdivided into a first floating area corresponding to the driver's seat, a second floating area shared by the driver and passenger, and a third floating area corresponding to the passenger seat.

[0318] At this time, the first and third floating areas can operate in SPM (Switchable Privacy Mode, SPM) mode. Specifically, 3D content displayed in the first floating area can operate in SPM mode so that only the driver can see it and the front passenger cannot. Additionally, 3D content displayed in the third floating area can operate in SPM mode so that only the front passenger can see it and the driver cannot see it.

[0319] Meanwhile, in the present invention, whether to operate the SPM mode for a segmented floating area can be determined based on the state of the vehicle.

[0320] Also, as another example, in the present invention, whether or not the SPM mode is driven and / or changed for a segmented floating area may vary depending on the shape (e.g., size, display area, etc.) and type of the 3D content being displayed.

[0321] Furthermore, in the present invention, not only the floating area, but also the prism area (821) formed on the upper part of the floating area may be driven in SPM mode depending on the vehicle status and / or the SPM mode operation may be changed depending on the shape, status, and type of the displayed content.

[0322] In this regard, FIG. 14 is an example for explaining that the viewing angle of the prism area (821) and the floating area (841) corresponding to the driver's seat and the passenger's seat in the vehicle display device (800) according to the present invention is adjusted.

[0323] In Fig. 14, the left area of ​​the prism area (821), the "Driver Essential Zone," can display driving-related information such as vehicle driving warnings and driving speed. When the SPM mode for the driver's seat is activated in the prism area (821), the viewing angle (1410) for the "Driver Essential Zone" is reduced to a certain range. Accordingly, the passenger in the passenger seat cannot view the driving-related information displayed in the prism area (821).

[0324] In the continuation, the 'control zone', which is the right area of ​​the prism area (821), may display menu icons, environmental control menus such as HVAC control, etc. When the SPM mode for the passenger seat is executed in the prism area (821), the viewing angle (1420) for the 'control zone' is reduced to a certain range. Accordingly, the environmental control menu displayed in the prism area (821) cannot be confirmed from the driver's seat.

[0325] Meanwhile, whether to execute the SPM mode for the prism area (821) can be determined independently from the floating area (841). In other words, in the vehicle display device (800) according to the embodiment of the present invention, whether to execute the SPM mode for the driver's seat and the SPM mode for the passenger seat in the prism area (821), and whether to execute the SPM mode for the driver's seat and the SPM mode for the passenger seat in the floating area (841) can be determined and performed independently.

[0326] Continuing, the left area of ​​the floating area (841) in FIG. 14 can be used as a 'Driver Private Zone', where vehicle driving-related warnings, vehicle status warnings, driver profiles, driver personal information (e.g., personal login information), etc. can be displayed as virtual 3D content. The displayed 3D content can have a variable display position or a changed depth depending on preset conditions (e.g., content type, whether it is linked to information displayed in the prism area, etc.). When the SPM mode for the driver's seat in the floating area (841) is executed, the viewing angle for the 'Driver Private Zone' is adjusted to a viewing angle (1410) that is reduced within a certain range. Accordingly, the passenger in the passenger seat cannot check the 3D content information displayed in the driver's private zone of the floating area (841).

[0327] The right area of ​​the floating area (841) can be used as a 'passenger private zone', where passenger personal information and profile, and content execution screens executed by the passenger can be displayed as 3D content types. The displayed 3D content can have a variable display position or a changed depth depending on preset conditions (e.g., content type, whether it is linked to information displayed in the prism area, etc.). When the SPM mode for the passenger seat is executed in the floating area (841), the viewing angle for the 'passenger private zone' is adjusted to have a viewing angle (1420) reduced within a certain range. Accordingly, the driver cannot check the 3D content information displayed in the passenger private zone of the floating area (841).

[0328] The area between the 'Driver Private Zone' and the 'Passenger Private Zone' in the floating area (841) can be used as a 'Sharing Zone', where 3D content for the driver and passenger to view together, such as a navigation execution screen, can be displayed. The displayed 3D content can have its display position changed or its depth changed according to preset conditions (e.g., type of content, whether it is linked to information displayed in the prism area, etc.). The 'Sharing Zone' is an area that is always shared regardless of whether the SPM mode for the passenger seat and / or the driver's seat is executed in the floating area (841). Therefore, both the driver and the passenger can always check the 3D content information displayed in the 'Sharing Zone'.

[0329] From now on, we will examine a structure that independently performs the various SPM modes described above in multiple areas. For this purpose, we will additionally refer to Figures 3 and 4 described above.

[0330] The housing (801) of the vehicle display device (800) has a display (810) positioned on the upper portion of the recessed inner space, and the display (810) may be positioned so as to be inclined at a certain angle rather than being parallel to the ceiling.

[0331] The communication unit (830) of the vehicle display device (800) can communicate with the vehicle (100) to receive status information. At this time, the status information includes not only the status information of the vehicle itself and the driving status information of the vehicle, but also the situation information inside the vehicle detected through sensors installed in the vehicle and the situation information outside (surrounding) the vehicle. For example, the presence, emotional state, facial expression, gesture, etc. of the driver and passengers detected through the vehicle's internal camera are also included as status information received through the communication unit (830).

[0332] As described above, the prism area (821) is a first screen area formed by refracting light emitted from the display (810) through the prism of the first reflection module (820). The prism area (821) can be operated in SPM mode at each position of the driver and passenger, so that each viewing angle can be reduced to within a certain range (SPM mode operation) or adjusted to exceed a certain range.

[0333] As described above, the floating area (841) is a second screen area formed by light emitted from the display (810) being reflected through the 3D plate of the second reflection module (840) or being refracted by a prism and then reflected through the 3D plate. The floating area (841) can be operated in SPM mode at each position of the driver and passenger, so that each viewing angle can be adjusted to be reduced within a certain range (SPM mode operation) or to be above a certain range.

[0334] Meanwhile, although not directly illustrated in FIGS. 3 and 4, the processor (850) may include a viewing angle adjustment module for adjusting the viewing angle according to the user's position in multiple screen areas. Specifically, some of the viewing angle adjustment modules may be included in the processor (850), and some / all of the modules may operate in conjunction with the processor (850).

[0335] The viewing angle adjustment module (1510 or 1710) may be formed in a partition-type structure as illustrated in FIG. 15 or in a film-type structure as illustrated in FIG. 17. A more detailed description thereof will be provided below with reference to FIG. 15 and FIG. 17.

[0336] The viewing angle adjustment module may be arranged to correspond to the front surface of the display (810). Here, being arranged to correspond to the front surface of the display (810) means that at least a portion of the viewing angle adjustment module is attached to the front surface of the display (810) (a), is arranged on the front surface of the 3D plate (b), or is arranged to be perpendicular to or inclined to the front surface of the display (810) (c). That is, the viewing angle adjustment module may be arranged to block some / all of the light (e.g., side light) emitted from the display (810) in a specific direction.

[0337] The viewing angle adjustment module can adjust the viewing angle so that light emitted from the display (810) is emitted within a certain angle range based on the operation of the processor (850).

[0338] Specifically, the processor (850) can control the operation of the viewing angle adjustment module so that the viewing angles for the first and second screen areas, i.e., the prism area and the floating area, change based on status information received from the vehicle (100) when the display (810) is driven.

[0339] At this time, the viewing angle adjustment module can independently adjust the viewing angles of the multiple sub-areas of the first reflection module (820) and the multiple sub-areas of the second reflection module (840) for each of the driver and the passenger, according to a driving signal from the processor (850).

[0340] In an embodiment, the viewing angle adjustment module may be a structure combined with a prism of the first reflection module (820) or a 3D plate of the second reflection module (840) in the form of a partition or film.

[0341] In another embodiment, the viewing angle adjustment module may be configured to include a plurality of viewing angle adjustment modules, for example, a first viewing angle adjustment module and a second viewing angle adjustment module, to independently perform the SPM mode (hereinafter, 'private mode') for each of a plurality of screen areas.

[0342] Specifically, in the embodiment, the viewing angle adjustment module may include a first viewing angle adjustment module arranged to correspond to a first sub-area corresponding to the driver's seat in the 3D plate of the second reflective module (840), and a second viewing angle adjustment module arranged to correspond to a second sub-area corresponding to the passenger seat in the 3D plate.

[0343] In this case, the processor (850) controls the first and second viewing angle adjustment modules, respectively, based on the status information received from the vehicle (100), so that the viewing angle for each of the first and second sub-areas is within or above a certain angle range. To this end, the processor (850) may be formed with a structure including first and second processors corresponding to the control of the first and second viewing angle adjustment modules, respectively.

[0344] In addition, in an embodiment, the processor (850) controls the viewing angle adjustment module based on the received vehicle status information, so as to adjust the viewing angle for a plurality of screen areas corresponding to the driver's seat and / or the passenger seat to be within a certain range or to be above a certain range.

[0345] In an embodiment, the processor (850) may control the viewing angle adjustment module so that light emitted from the display (810) in the first vehicle state is emitted over a certain angle range. Specifically, the processor (850) may control the first and second viewing angle adjustment modules so that light emitted from the display (810) in the first vehicle state is emitted over a certain angle range from a prism region and / or a floating region corresponding to the driver's seat and / or a prism region and / or a floating region corresponding to the passenger seat.

[0346] Here, the first vehicle state may be one in which the privacy of the driver and / or passengers is not required and / or driving is not disrupted. For example, this may be the case when only the driver or front passenger is in the vehicle, or when the vehicle is in autonomous driving mode.

[0347] In addition, in an embodiment, the processor (850) may control the viewing angle adjustment module so that the light emitted from the display (810) in the second vehicle state is emitted only within a certain angular range. Specifically, the processor (850) may control the first and second viewing angle adjustment modules so that the light emitted from the display (810) in the second vehicle state is emitted within a certain angular range from the prism region and / or floating region corresponding to the driver's seat and / or the prism region and / or floating region corresponding to the passenger seat.

[0348] Here, the second vehicle state may be one that requires privacy protection for the driver and / or passengers and / or poses a risk of interference with driving. For example, this may be the case when both the driver and passenger are in the vehicle when the display (810) is operating, or when the vehicle is in manual driving mode.

[0349] As described above, vehicle status information may be included as one of the conditions for driving the viewing angle adjustment module.

[0350] In an embodiment, vehicle status information received from the vehicle (100) may include passenger information sensed through the vehicle's internal camera. In this case, the first vehicle status described above may be a state in which the vehicle's passenger seat is not detected, and the second vehicle status described above may be a state in which the vehicle's passenger seat is detected.

[0351] The processor (850) may control the viewing angle adjustment module so that, based on the detection of a passenger in the vehicle's front seat, the viewing angle of the prism area and / or floating area corresponding to the passenger seat and / or the prism area and / or floating area corresponding to the driver's seat is adjusted to a predetermined range when the display (810) is driven. Here, the predetermined range may be, for example, ±45 to ±60 degrees up and down and / or left and right.

[0352] In another embodiment, vehicle status information received from the vehicle (100) may include information regarding the vehicle's driving mode. In this case, the aforementioned first vehicle status may be an autonomous driving mode or a stopped state, and the aforementioned second vehicle status may be a state in which the vehicle is operating in a manual driving mode.

[0353] The processor (850) may control the viewing angle adjustment module so that the viewing angle for the prism area and / or floating area corresponding to the passenger seat is adjusted within a certain range for safe driving when the display (810) is driven based on the vehicle operating in manual driving mode. Here, the certain angle range may be, for example, ±45 to ±60 degrees up and down and / or left and right. Meanwhile, the certain angle range may be stored in advance in the memory and may be varied according to settings / inputs or control of the processor (850).

[0354] As described above, the vehicle display device according to an embodiment of the present invention can selectively perform a privacy mode for real and virtual images displayed on the driver's seat and the passenger's seat, respectively, based on the vehicle status.

[0355] Hereinafter, with reference to FIGS. 15 and 16, a method for adjusting the viewing angle of the prism area and the floating area through a viewing angle adjustment module (1510) formed in a bulkhead type will be specifically described.

[0356] Referring to FIG. 15, a plurality of transparent partition walls (1510a, 1510b) for adjusting the viewing angle from the driver's seat and the passenger's seat can be combined with the 3D plate of the second reflective module (840). Referring to FIG. 15 and FIG. 16 together, the plurality of transparent partition walls (1510a, 1510b) can be arranged to not only divide the 3D plate of the second reflective module (840) into a plurality of sub-regions, but also divide the prism of the first reflective module (820) into a plurality of sub-regions.

[0357] A plurality of transparent partition walls (1510a, 1510b) are arranged to correspond to the front surface of the display (810), and are formed at a certain interval in the longitudinal direction. Referring to FIG. 15, the first transparent partition wall (1510a) is arranged at a 1 / 3 point (or 2 / 3 point) of the display (810), and the second transparent partition wall (1510b) is arranged at a 2 / 3 point (or 1 / 3 point) of the display (810).

[0358] One side of the plurality of transparent partition walls (1510a, 1510b) may be arranged to contact the display (801), and the other side may be arranged to contact parts of the first and second reflective modules (820, 840).

[0359] The processor (850) determines whether to drive each of the viewing angle adjustment module and the plurality of transparent partitions (1510a, 1510b) based on the status information received from the vehicle (100). According to a drive signal (e.g., a voltage application signal, etc.) determined by the processor (850), each of the plurality of transparent partitions (1510a, 1510b) blocks the side light emitted from the display (810) to control the light to be emitted within a certain angle range or to be emitted beyond a certain angle range.

[0360] In an embodiment, one side of each of the plurality of transparent partition walls (1510a, 1510b) is coupled to the display (810), and at this time, a protective layer or adhesive may be additionally placed between the display (810) and the plurality of transparent partition walls (1510a, 1510b).

[0361] In an embodiment, a first transparent partition (1510a) of the plurality of transparent partitions (1510a, 1510b) may be arranged between a first sub-region for the driver's seat and a second sub-region for the passenger seat in the second screen area, i.e., the floating area. In addition, a second transparent partition (1510b) of the plurality of transparent partitions (1510a, 1510b) may be arranged between the second sub-region and a third sub-region for the passenger seat in the second screen area, i.e., the floating area.

[0362] In this case, the processor (850) can control the viewing angle adjustment module to adjust the viewing angle of at least one of the first and third sub-areas by blocking side light emitted from the display (810) through at least one of the first and second transparent partitions (1510a, 1510b) based on the status information received from the vehicle (100).

[0363] In an embodiment, the interior of a plurality of transparent partitions (1510a, 1510b) may be filled with a light-blocking material. Each of the plurality of transparent partitions (1510a, 1510b) may open a path for light emitted from the display (810) or block a path for light in a specific direction under the control of the processor (850).

[0364] When the sides corresponding to the driver's seat and / or passenger seat are blocked by multiple transparent partitions (1510a, 1510b), only the driver can view the information displayed in the prism area and floating area in the driver's seat, and the information displayed cannot be viewed by those around him / her. Similarly, in the passenger seat, only the passenger can view the information displayed in the prism area and floating area, and the information displayed cannot be viewed by those around him / her.

[0365] Referring to FIGS. 15 and 16, the first processor (850a) is linked to the first transparent partition (1510a) to determine whether to perform the SPM mode for the screen area (prism area and / or floating area) corresponding to the driver's seat and to perform an operation according to the determination.

[0366] The second processor (850b) is linked to the second transparent partition (1510b) to determine whether to perform the SPM mode for the screen area (prism area and / or floating area) corresponding to the auxiliary seat, and to perform an operation according to the determination.

[0367] The first and second transparent partitions (1510a, 1510b) may have predetermined widths and heights and may be arranged at predetermined intervals.

[0368] The first and second transparent partition walls (1510a, 1510b) may be formed of a transparent resin. To this end, the first and second transparent partition walls (1510a, 1510b) may be manufactured through processes such as silkscreening, embossing, photolithography, and / or imprinting.

[0369] The first and second transparent partition walls (1510a, 1510b) may be composed of a transparent light-transmitting material. At this time, the light-transmitting material may be composed of, for example, a photocurable resin such as a UV resin or a photoresist resin, or may be composed of at least one of a urethane resin and an acrylic resin.

[0370] The first and second transparent partitions (1510a, 1510b) are shown as being arranged perpendicular to the display (810), but are not limited thereto and may be arranged to be inclined to form a certain angle with the display (810).

[0371] The processor (850) can operate to easily transmit light incident on the first and second transparent partitions (1510a, 1510b) or to block a portion of light emitted in a specific direction. Specifically, the first processor (850a) can be linked to the first transparent partition (1510a) to block side light so that information displayed on the prism region and floating region corresponding to the driver's seat has a viewing angle within a certain angular range. In addition, the second processor (850b) can be linked to the second transparent partition (1510b) to block side light so that information displayed on the prism region and floating region corresponding to the passenger seat has a viewing angle within a certain angular range. Meanwhile, information displayed on the prism region and floating region corresponding to the sharing region between the first and second transparent partitions (1510a, 1510b) is not blocked and can be confirmed at both locations corresponding to the driver's seat and the passenger seat.

[0372] In this way, independent driving of the first and second transparent partitions (1510a, 1510b) by the first and second processors (850a, 850b) can be performed based on status information received from the vehicle (e.g., whether a passenger in the passenger seat is detected, the vehicle's driving mode, etc.).

[0373] Additionally, in some embodiments, independent driving of the first and second transparent partitions (1510a, 1510b) by the first and second processors (850a, 850b) may be performed differently based on the type of content displayed in the plurality of prism areas and floating areas formed by the first and second reflective modules (820, 840).

[0374] Hereinafter, with reference to FIGS. 17 and 18, a method for adjusting the viewing angle of the prism area and the floating area through a viewing angle adjustment module (1520) formed in a film type will be specifically described.

[0375] Referring to Fig. 17, a viewing angle adjustment film (1710) for adjusting the viewing angle in the driver's seat and the passenger's seat can be combined with the 3D plate of the second reflective module (840). Referring to Figs. 17 and 18 together, the viewing angle adjustment film (1710) is formed to be divided into a plurality of sub-regions, so that not only the 3D plate of the second reflective module (840) is divided into a plurality of sub-regions, but also the prism of the first reflective module (820) can be arranged to be divided into a plurality of sub-regions. In this case, the viewing angle adjustment films matching the divided plurality of sub-regions can be linked to different processors, for example, the first and second processors (850a, 850b).

[0376] In an embodiment, the viewing angle adjustment module, i.e., the viewing angle adjustment film (1710), can adjust the viewing angle so that light emitted from the display (810) is emitted within or above a certain angle range based on a voltage applied to a plurality of electrodes disposed on the display (810).

[0377] To this end, the processor (850) determines whether to block light outside a certain angle range, i.e., whether to perform SPM mode, based on status information received from the vehicle (100), and can control to apply a variable voltage to multiple electrodes of the viewing angle adjustment module according to the determination.

[0378] The viewing angle adjustment film arranged for viewing angle adjustment can be formed with a structure in which a plurality of films, for example, first and second films, a light conversion layer, and an adhesive layer are deposited.

[0379] The processor (850) may be operable to control the size of the electric field by applying / not applying a voltage to the light conversion layer. To this end, a first film may include a first electrode, a light conversion layer and a plurality of adhesive layers may be deposited on the first film, and a second film including a second electrode may be sequentially arranged on the first film so as to face the first film. In this case, the first and second electrodes may each include a transparent conductive material.

[0380] Through this film structure, it is possible to block a portion of the light emitted in a specific direction, for example, side light, so that the light emitted from the display (810) is emitted only within a certain angle range.

[0381] Specifically, when voltage is applied to the first and second electrodes through the processor (850) and an electric field is formed between the first and second films, light emitted from the display (810) becomes within a certain angular range or more. In addition, when voltage is controlled not to be applied to the first and second electrodes through the processor (850) and an electric field is not formed between the first and second films, light emitted from the display (810) becomes within a certain angular range and operates in the SPM mode.

[0382] In this way, when no electric field is formed between the first and second films, the prism region and / or the floating region operate in SPM mode. This is because the orphan blocking particles contained in the first and second films block light (e.g., side light) emitted from the display (810) in a specific direction.

[0383] The light conversion layer disposed between the first and second films includes light-blocking particles. These light-blocking particles allow the light-absorbing carbon particles to block light, thereby enabling operation in SPM mode. These light-blocking particles move in one direction when an electric field is formed. Thus, the carbon particles are unable to block light, allowing light emitted from the display (810) to have a viewing angle exceeding a certain angle range.

[0384] In the present invention, a plurality of independently controllable films are formed for each of the plurality of sub-regions of the prism region (821) and / or each of the sub-regions corresponding to the driver's seat and the passenger's seat of the floating region (841), so that when the display (810) is driven, the SPM mode can be operated or not operated for each of the sub-regions.

[0385] In another embodiment, the processor (850) can adjust the voltage applied to the electrodes of each viewing angle adjustment module corresponding to multiple sub-regions of the prism region (821) and the floating region (841) in different magnitudes. Accordingly, the viewing angle range for the screen region linked to each viewing angle adjustment module can be independently adjusted to vary.

[0386] In an embodiment, the processor (850) operates so as not to apply voltage to a plurality of electrodes matching the viewing angle adjustment film in a first operation mode (i.e., SPM) that blocks light outside the predetermined angle range based on status information received from the vehicle.

[0387] In addition, the processor (850) can control to apply a preset voltage (or variable voltage) to a plurality of electrodes matching the viewing angle adjustment film in a second operation mode that does not block light outside the predetermined angle range based on status information received from the vehicle.

[0388] Meanwhile, as described above, the first and second screen areas formed through the first and second reflective modules (820, 840) can be divided into a first sub-area for the driver's seat, a second sub-area for the share, and a third sub-area for the passenger seat.

[0389] In this case, the viewing angle adjustment module, i.e., the viewing angle adjustment film (1710), may be formed to include a first plurality of electrodes for adjusting the viewing angle for the first sub-region and a second plurality of electrodes for adjusting the viewing angle for the third sub-region.

[0390] Additionally, in an embodiment, the processor (850) can independently control the voltages applied to the first and second plurality of electrodes so that the viewing angles for the first and third sub-regions are controlled, respectively, based on status information received from the vehicle.

[0391] Specifically, as illustrated in FIGS. 17 and 18, the first processor (850a) is linked to the left side of the viewing angle adjustment film (1710) to determine whether to perform the SPM mode for the screen area (prism area and / or floating area) corresponding to the driver's seat and to perform an operation according to the determination.

[0392] For example, the first processor (850a) can control the viewing angle for the screen area (prism area and / or floating area) corresponding to the driver's seat to be within a certain angular range or more by applying voltage to the plurality of electrodes arranged on the left side of the viewing angle adjustment film (1710) to form an electric field. In addition, for example, the first processor (850a) can control the viewing angle for the screen area (prism area and / or floating area) corresponding to the driver's seat to be within a certain angular range and operate in the SPM mode by not applying voltage to the plurality of electrodes arranged on the left side of the viewing angle adjustment film (1710).

[0393] In addition, for example, the second processor (850b) can control the viewing angle for the screen area (prism area and / or floating area) corresponding to the auxiliary seat to be within a certain angular range or more by applying voltage to the plurality of electrodes arranged on the right side of the viewing angle adjustment film (1710) to form an electric field. In addition, for example, the second processor (850b) can control the viewing angle for the screen area (prism area and / or floating area) corresponding to the auxiliary seat to be within a certain angular range and operate in the SPM mode by not applying voltage to the plurality of electrodes arranged on the right side of the viewing angle adjustment film (1710).

[0394] As described above, the vehicle display device according to an embodiment of the present invention can independently and selectively perform a privacy mode for real and virtual images displayed on the driver's seat and the passenger's seat, respectively, based on the vehicle status, by using a bulkhead-type viewing angle adjustment module and a film-type viewing angle adjustment module.

[0395] Below, FIG. 19 is an example of adjusting the viewing angle from the driver's seat through a vehicle display device according to an embodiment of the present invention, and FIG. 20 is an example of adjusting the viewing angle from the passenger seat through a vehicle display device.

[0396] Specifically, Fig. 19 illustrates the viewing angle range that can be seen by the passenger in the driver's seat depending on whether the SPM mode for the passenger seat is activated. Furthermore, Fig. 20 illustrates the viewing angle range that can be seen by the passenger in the passenger seat depending on whether the SPM mode for the driver's seat is activated.

[0397] Referring to FIG. 19, when the SPM mode is executed for the prism area (821) and / or the floating area (841) corresponding to the passenger seat, the driver can check the information displayed on the prism area (821) and / or the floating area (841) within a certain angle range of view (1910). In this case, the driver cannot view the information displayed on the prism area (821) and / or the floating area (841) corresponding to the passenger seat from his / her position.

[0398] Similarly, while the SPM mode for the prism area (821) and / or the floating area (841) corresponding to the passenger seat is not running, the driver can check the information displayed on the prism area (821) and / or the floating area (841) at a viewing angle (1920) greater than a certain angular range. In this case, the driver can view the information displayed on the prism area (821) and / or the floating area (841) corresponding to the passenger seat from his / her own position.

[0399] Continuing with reference to FIG. 20, when the SPM mode is executed for the prism area (821) and / or the floating area (841) corresponding to the driver's seat, the passenger in the passenger seat can check the information displayed in the prism area (821) and / or the floating area (841) within a certain angle range of view (2010). In this case, the passenger in the passenger seat cannot view the information displayed in the prism area (821) and / or the floating area (841) corresponding to the driver's seat from his / her position.

[0400] Similarly, while the SPM mode for the prism area (821) and / or the floating area (841) corresponding to the driver's seat is not running, the passenger in the passenger seat can check the information displayed in the prism area (821) and / or the floating area (841) at a viewing angle (2020) greater than a certain angular range. In this case, the passenger in the passenger seat can view the information displayed in the prism area (821) and / or the floating area (841) corresponding to the driver's seat from his / her own position.

[0401] Meanwhile, the processor (850) can adjust the above-described angle range to match the position and posture of the driver in the driver's seat and the passenger in the passenger seat based on the passenger information received from the vehicle (100).

[0402] As described above, the vehicle display device according to an embodiment of the present invention can selectively or simultaneously perform multiple different display modes with a single display module. For example, real and virtual images can be selectively or simultaneously displayed with a single display. Furthermore, the position of the floating 3D virtual image can be varied based on the user's viewing angle, content type, or movement, thereby displaying graphic images that match the user's field of view and maximize immersion and floating effects. Furthermore, privacy mode can be selectively performed for real and virtual images displayed on the driver's seat and passenger's seat, respectively, based on vehicle status. Specifically, privacy mode can be performed on multiple screens displayed on the passenger seat when a passenger is detected and the display is activated. Furthermore, privacy mode can be performed on multiple screens displayed on the passenger seat during manual driving to ensure that the driver's driving is not interrupted. Furthermore, privacy mode can be performed on multiple screens displayed on the driver's seat during driving to protect the driver's privacy. In this way, by adjusting the viewing angle for each of the driver's seat and passenger seat to a certain range or above depending on the vehicle condition, the user's privacy is protected and a variety of user environments are provided.

[0403] The present invention described above can be implemented as computer-readable code on a medium in which a program is recorded. Computer-readable media include 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 include media implemented in the form of carrier waves (e.g., transmission via the Internet). In addition, the computer may include a 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.
