[0040] Figure 1 is a block diagram illustrating a display apparatus of a vehicle according to an embodiment of the present disclosure.

[0041] Reference Figure 1 According to an embodiment of the present disclosure, a display apparatus 100 for a vehicle may include a first display device 110 , a second display device 120 , a first controller 130 , and a second controller 140 .

[0042] The first display device 110 may display information related to the vehicle. For example, the first display device 110 may include at least any one of a high-resolution LED, an LED array, an LED matrix, or a digital mirror device (DMD).

[0043] The first display device 110 may display an image including vehicle-related information in the first display area. For example, the first display device 110 may display an image including first information and second information related to the vehicle. For another example, the first information and the second information may include at least one of the vehicle's heading, vehicle speed, vehicle travel path, road speed limit, remaining distance to the destination, or information about obstacles, but the present disclosure is not limited thereto.

[0044] According to an embodiment, the first display device 110 may include a light. For example, the first display device 110 may include a left light of the vehicle.

[0045] The second display device 120 may display information related to the vehicle. For example, the second display device 120 may include at least any one of a high-resolution LED, an LED array, an LED matrix, or a digital mirror device (DMD).

[0046] The second display device 120 may display an image including vehicle-related information in the second display area. For example, the second display device 120 may display an image including first information and second information related to the vehicle. For another example, the first information and the second information may include at least one of the vehicle's heading, vehicle speed, vehicle travel path, road speed limit, remaining distance to the destination, or information about obstacles, but the present disclosure is not limited thereto.

[0047] According to an embodiment, the second display device 120 may be included in a lamp. For example, the second display device 120 may include a left lamp of a vehicle.

[0048] According to an embodiment, the first display device 110 and the second display device 120 may display images simultaneously. For example, the first display device 110 may display an image including first information related to the vehicle, while the second display device 120 may display an image including second information related to the vehicle.

[0049] According to another embodiment, only one of the first display device 110 and the second display device 120 may display an image. For example, the first display device 110 may display an image containing both the first information and the second information related to the vehicle, while the second display device 120 may not display an image. In this case, since only the first display device 110 displays the image, the image can be displayed without distortion even when the vehicle vibrates or impacts.

[0050] The first controller 130 may obtain information about the behavior of the vehicle (i.e., vehicle behavior information). For example, the information about the behavior of the vehicle may include at least one of information about vehicle vibration (i.e., vehicle vibration information) or information about expected vehicle vibration (i.e., vehicle vibration prediction information). For example, the information about the behavior of the vehicle may include at least one of information about a vehicle collision, information about an impact on the vehicle, information about an expected vehicle collision, or information about an expected impact on the vehicle.

[0051] The first controller 130 may control the operation of the first display device 110 based on the acquired information about the vehicle's behavior. For example, the first controller 130 may control whether to display an image through the first display device 110, and may control at least one of the direction, angle, position, height, range, brightness, luminance, color, time, and information used to display the image to be displayed through the first display device 110. For example, information about expected vehicle vibration may be acquired based on the vehicle's travel path, vehicle position, or traffic information.

[0052] The second controller 140 may acquire information about the behavior of the vehicle. For example, the information about the behavior of the vehicle may include at least one of information about vehicle vibration or information about expected vehicle vibration. For example, the information about the behavior of the vehicle may include at least one of information about a vehicle collision, information about an impact on the vehicle, information about an expected vehicle collision, or information about an expected impact on the vehicle.

[0053] The second controller 140 may control the operation of the second display device 120 based on the acquired information about the behavior of the vehicle. For example, the second controller 140 may control whether to display an image through the second display device 120, and may control at least one of the direction, angle, position, height, range, brightness, luminance, color, time, and information for displaying the image to be displayed through the second display device 120.

[0054] Figure 2 2 are diagrams illustrating two modes in which a display device of a vehicle displays an image according to an embodiment of the present disclosure.

[0055] Reference Figure 2 According to an embodiment of the present disclosure, the display device 100 of a vehicle may display an image in front of the vehicle in two modes.

[0056] “Mode 1” is a mode in which an image is displayed only by the first display device 110 included in the display apparatus 100 of the vehicle.

[0057] “Mode 2” is a mode in which an image is displayed by both the first display device 110 and the second display device 120 included in the display apparatus 100 of the vehicle.

[0058] With reference to "Mode 1" and "Mode 2," there is no difference between area 1 for displaying an image when only the first display device 110 displays an image and area 2 for displaying an image when both the first display device 110 and the second display device 120 display an image. In other words, even if only the first display device 110 displays an image, an image including information related to the vehicle can be displayed to the driver.

[0059] Although Figure 2 Although not shown, "Mode 3," which is a mode for displaying images only through the second display device 120, is also possible. When displaying images in "Mode 3," images including vehicle-related information can be displayed to the driver, similar to the comparison between "Mode 1" and "Mode 2." In other words, the vehicle's display device 100 can display images only through either the first display device 110 or the second display device 120. When compared to displaying images through both the first display device 110 and the second display device 120, displaying images through only one display device produces no difference in effect.

[0060] Figure 3 FIG. 1 is a diagram illustrating an example of an image displayed by one display device of a display apparatus of a vehicle according to an embodiment of the present disclosure. Figure 3 It is illustrated that the first display device 110 is located on the left side of the vehicle 10 and the second display device 120 is located on the right side of the vehicle 10 , but the present disclosure is not limited thereto.

[0061] Reference Figure 3 According to an embodiment of the present disclosure, the display device 100 of the vehicle can display an image through one display device. For example, the first display device 110 can display an image, while the second display device 120 may not display an image.

[0062] The first controller 130 may control the first display device 110 to display an image. For example, the first controller 130 may control only the first display device 110 to display an image by sending a control signal to the second controller 140 for controlling the second display device 120 not to display an image. For another example, each of the first controller 130 and the second controller 140 may determine that only the first display device 110 displays an image, the first controller 130 may control the first display device 110 to display an image, and the second controller 140 may control the second display device 120 not to display an image.

[0063] According to an embodiment, the display device 100 of the vehicle 10 may display an image through the second display device 120 and may not display the image through the first display device 110. In this case, the second controller 140 may control the second display device 120 to display the image, and the first controller 130 may control the first display device 110 not to display the image.

[0064] Figure 4 is a diagram illustrating two modes of alternately displaying images through a display device of a vehicle according to an embodiment of the present disclosure. Figure 4 It is illustrated that the first display device 110 is located on the left side of the vehicle 10 and the second display device 120 is located on the right side of the vehicle 10 , but the present disclosure is not limited thereto.

[0065] The first controller 130 and the second controller 140 may respectively control the first display device 110 and the second display device 120 to alternately display images. For example, alternately displaying images may mean displaying an image only through either the first display device 110 or the second display device 120.

[0066] According to an embodiment, the first controller 130 may determine which display device displays an image among the first display device 110 or the second display device 120. For example, the first controller 130 may determine which display device displays an image among the first display device 110 or the second display device 120 based on information about the behavior of the vehicle. According to an embodiment, in a default state, the first controller 130 may set the first display device 110 to display an image and may set the second display device 120 not to display an image. According to another embodiment, the second controller 140 may determine which display device displays an image among the first display device 110 or the second display device 120.

[0067] When the first display device 110 displays an image, the first controller 130 may send a control signal to the second controller 140 to prevent the second controller 140 from displaying the image. For example, when receiving the control signal from the first controller 130, the second controller 140 may control the second display device 120 to not display the image.

[0068] When it is determined that the first display device 110 fails to display an image, the first controller 130 may send a control signal to the second display device 120 so that the second display device 120 displays an image. For example, when receiving the control signal from the first controller 130, the second controller 140 may control the second display device 120 to display an image.

[0069] According to an embodiment, the first controller 130 may determine that the first display device 110 has failed to display an image in at least one of the following situations: a situation where vibration is expected relative to the first display device 110; a situation where an impact is expected relative to the first display device 110; a situation where vibration is expected relative to the first display device 110; and a situation where vibration is expected relative to the first display device 110 and an obstacle is present in front of the first display device 110. In this case, the first controller 130 may allow the second controller 140 to display an image through the second display device 120.

[0070] According to an embodiment, even if the image display by the first display device 110 does not fail, when the image display by the second display device is more efficient, the first controller 130 may send a control signal to the second controller 140 to display the image by the second display device 120. For example, when the vehicle 10 turns in the direction in which the second display device 120 is provided, the first controller 130 may determine that the image display by the second display device 120 is more efficient in any of the following cases: the second display device 120 displays the image more smoothly than the first display device 110; or a part of the first display device 110 is faulty.

[0071] According to an embodiment of the present disclosure, the display device 100 of the vehicle 10 can control the first display device 110 or the second display device 120 based on information about the behavior to alternately display images including information related to the vehicle, thereby providing the driver with images without image distortion and matching the vehicle condition.

[0072] Figure 5 2 is a diagram illustrating that a display device of a vehicle simultaneously displays images according to an embodiment of the present disclosure.

[0073] Reference Figure 5 According to an embodiment of the present disclosure, the display device 100 of the vehicle 10 can simultaneously display images through the first display device 110 and the second display device 120. For example, the first controller 130 and the second controller 140 can control the first display device 110 and the second display device 120 to simultaneously display images based on information about the behavior of the vehicle 10.

[0074] When displaying images simultaneously, the display device 100 of the vehicle 10 allows the first display device 110 and the second display device 120 to synchronize with each other to display images, thereby reducing image distortion. To this end, the first controller 130 can generate a clock signal and can send the generated clock signal to the second controller 140. In this case, the first controller 130 can control the first display device 110 to display the image based on the generated clock signal, and the second controller 140 can control the second display device 120 to display the image based on the clock signal received from the first controller 130. In other words, the second controller 140 can synchronize to display the image based on the received clock signal. According to an embodiment, the second controller 140 can generate a clock signal and can send the clock signal to the first controller 130 to synchronize with the first controller 130 to display the image.

[0075] Reference Figure 6 When simultaneously displaying images and upon acquiring specific information, the display device 100 of the vehicle 10 may perform a control operation to cause one display device to display an image. For example, the specific information may be information regarding the behavior of the vehicle 10. The information regarding the behavior of the vehicle 10 may include at least any one of information regarding vibration of the vehicle 10, information regarding expected vibration of the vehicle 10, information regarding collisions of the vehicle 10, information regarding impacts to the vehicle 10, and information regarding expected impacts to the vehicle 10. When, based on the information regarding the behavior of the vehicle 10, it is determined that vehicle vibration is present or is expected, the first controller 130 may send a control signal to the second controller 140 to prevent the second display device 120 from simultaneously displaying an image. For example, upon receiving the control signal, the second controller 140 may stop the second display device 120 from displaying an image. Therefore, since the first display device 110 displays the entire image, distortion of the displayed image can be reduced.

[0076] According to another embodiment, the first controller 130 and the second controller 140 may acquire information about the behavior of the vehicle 10. When there is vibration of the vehicle 10 or when vibration of the vehicle 10 is expected, the first controller 130 may control the first display device 110 to display all images, and the second controller 140 may control the second display device 120 to not display any images.

[0077] Figure 7 is a flowchart illustrating a method for operating a display device of a vehicle according to an embodiment of the present disclosure.

[0078] Reference Figure 7According to an embodiment of the present disclosure, a method for operating a display device 100 of a vehicle 10 may include: controlling the operation of a first display device to display an image including first information and second information related to the vehicle to a first display area based on information acquired about the behavior of the vehicle (S110); and controlling the operation of a second display device to display an image to a second display area based on information acquired about the behavior of the vehicle (S120).

[0079] In controlling the operation of the first display device to display an image including first and second information related to the vehicle on the first display area based on the acquired information about the vehicle's behavior (S110), the first controller 130 may control the operation of the first display device 110. For example, the first controller 130 may control the first display device 110 to display an image including first and second information related to the vehicle on the first display area. For another example, the first and second information related to the vehicle may include at least one of the vehicle's heading, the vehicle's speed, the vehicle's driving path, the road's speed limit, the remaining distance to the destination, or information about obstacles.

[0080] In controlling the operation of the second display device to display an image in the second display area based on the acquired information about the behavior of the vehicle (S120), the second controller 140 may control the operation of the second display device 120. For example, the second controller 140 may control the second display device 120 to display an image in the second display area.

[0081] Figure 8 and Figure 9 is a flowchart illustrating in detail a method for operating a display device of a vehicle according to an embodiment of the present disclosure.

[0082] Reference Figure 8 According to an embodiment of the present disclosure, a method for operating a display device 100 for a vehicle includes: individually controlling a first display device and a second display device so that the first display device and the second display device alternately display images (S210); sending a control signal to prevent the second display device from displaying an image (S220); and when it is determined that the first display device fails to display an image, sending a control signal to cause the second display device to display an image (S230). According to an embodiment, S210 to S230 may include Figure 7 Any one of S110 to S120.

[0083] In individually controlling the first display device and the second display device so that the first display device or the second display device alternately displays an image (S210), the first controller 130 and the second controller 140 may respectively control the first display device 110 and the second display device 120 so that the first display device 110 and the second display device 120 alternately display images. For example, when the first controller 130 controls the first display device 110 to display an image, the second controller 140 may control the second display device 120 not to display an image. When the first controller 130 controls the first display device 110 not to display an image, the second controller 140 may control the second display device 120 to display an image. In other words, the first controller 130 and the second controller 140 may perform a control operation so that only one of the first display device 110 and the second display device 120 displays an image.

[0084] In transmitting a control signal to prevent the second display device from displaying an image (S220), when the first controller 130 controls the first display device 110 to display an image, the first controller 130 may transmit a control signal to the second controller 140 to prevent the second display device 120 from displaying an image. For example, based on the control signal received from the first controller 130, the second controller 140 may control the second display device 120 to prevent the second display device 120 from displaying an image. Depending on the embodiment, when S230 is executed, S220 may not be executed. According to another embodiment, when the first display device 110 and the second display device 120 are displaying images simultaneously, S220 may not be executed.

[0085] When it is determined that the first display device has failed to display an image, in the step of transmitting a control signal to cause the second display device to display an image (S230), the first controller 130 may transmit a control signal to the second controller 140 to cause the second display device 120 to display an image. For example, the second controller 140 may control the second display device 120 to display an image based on the control signal received from the first controller 130. Depending on the embodiment, S230 may not be executed when S220 is executed. According to another embodiment, S230 may not be executed when the first display device 110 and the second display device 120 are displaying images simultaneously.

[0086] Reference Figure 9According to an embodiment of the present disclosure, the method for operating the display device 100 of a vehicle may further include: based on information about the behavior of the vehicle, individually controlling the first display device and the second display device so that an image is projected simultaneously (S310); sending a clock signal (S320); synchronizing to display an image based on the clock signal (S330); and sending a control signal when there is vehicle vibration or when vehicle vibration is expected, so that the second display device is prevented from projecting an image simultaneously (S340). According to an embodiment, S310 to S340 may include Figure 7 At least any one of S110 to S120.

[0087] In the step of individually controlling the first and second display devices based on the information about the behavior of the vehicle so that images are projected simultaneously (S310), the first controller 130 and the second controller 140 may control the first and second display devices 110 and 120 based on the information about the behavior of the vehicle 10 so as to project images simultaneously. The information about the behavior of the vehicle 10 may include at least any one of information about vibration of the vehicle 10, information about expected vibration of the vehicle 10, information about a collision of the vehicle 10, information about an impact on the vehicle 10, information about an expected collision of the vehicle, and information about an expected impact on the vehicle 10.

[0088] In transmitting the clock signal ( S320 ), the first controller 130 may generate a clock signal and may transmit the generated clock signal to the second controller 140 .

[0089] In synchronization based on a clock signal to display an image (S330), the second controller 140 can synchronize to display an image based on the received clock signal, for example, the first controller 130 can control the first display device 110 to display an image based on the generated clock signal, and the second controller 140 can control the second display device 120 to display an image based on the received clock signal, so that the first display device 110 and the second display device 120 are synchronized with each other to display images simultaneously.

[0090] In the step of transmitting a control signal when vehicle vibration is present or expected to prevent the second display device from simultaneously projecting an image (S340), when the first controller 130 determines based on the information about the behavior of the vehicle 10 that vehicle vibration is present or expected, the first controller 130 may transmit a control signal to the second controller 140 to prevent the second display device 120 from simultaneously projecting an image. For example, the second controller 140 may control the second display device 120 based on the received control signal to prevent the second display device 120 from displaying an image and allow the first display device 110 to display the entire image.

[0092] Reference Figure 10 According to an embodiment of the present disclosure, a vehicle 1000 may include a sensor 1100 and a display device 1200 .

[0093] The sensor 1100 may sense information about the vehicle 1000. For example, the sensor 1100 may acquire information about the behavior of the vehicle. As another example, the sensor 1100 may sense at least any one of information about the vibration of the vehicle 1000, information about expected vibration of the vehicle 1000, information about a collision of the vehicle 1000, information about an impact on the vehicle 1000, information about an expected collision of the vehicle, and information about an expected impact on the vehicle 1000. Depending on the embodiment, the sensor 1100 may include at least one of an acceleration sensor, a lidar sensor, a camera sensor, and a radar sensor. The sensor 1100 may transmit the sensed information to the display device 1200.

[0094] The display device 1200 may include a display apparatus 1210 and a controller 1220. The display device 1200 may display an image in front of the vehicle 1000. For example, the display device 1200 may be associated with either the left headlight or the right headlight of the vehicle 1000. For another example, the display device 1200 may be included in the headlight of the vehicle 1000.

[0095] According to an embodiment, the display device 1200 may be included in only one of the headlights of the vehicle 1000. In other words, the display device 1200 may not be included in a headlight different from the headlight including the display device 1200. For example, the display device 1200 may be included in the left headlight of the vehicle 1000, but may not be included in the right headlight of the vehicle 1000. Although Figure 10 The display device 1200 is illustrated as being included in the left headlight of the vehicle 1000, but the present disclosure is not limited thereto. For example, the display device 1200 may be included in the right headlight of the vehicle 1000. In this case, the display device 1200 may not be included in the left headlight.

[0096] For example, the display device 1210 may display an image including first information and second information related to the vehicle. For another example, the first information and second information related to the vehicle may include at least one of the vehicle's heading, vehicle speed, vehicle travel path, road speed limit, remaining distance to the destination, or information about obstacles.

[0097] The controller 1220 may control the operation of the display device 1210. For example, the controller 1220 may control the display device 1210 to display an image based on information about the behavior of the vehicle.

[0098] According to an embodiment, in the vehicle 1000, the display device 1200 may not be installed in a headlamp other than the headlamp including the display device 1200, and the headlamp including the display device 1200 may be treated as a dummy. In this case, when the headlamp including the display device 1200 is treated as a dummy, the manufacturing cost of the vehicle 1000 can be reduced.

[0099] According to an embodiment of the present disclosure, in a display device of a vehicle, since display is controlled based on behavior information of the vehicle, an image can be output without image distortion even when vibration and / or shock occurs in the vehicle.

[0100] According to an embodiment of the present disclosure, a display device of a vehicle can perform a control operation so that images are alternately displayed through opposing display devices, thereby effectively displaying images according to the driving condition of the vehicle.

[0101] According to an embodiment of the present disclosure, when images are displayed simultaneously on opposing display devices, the display devices of a vehicle can synchronize the images based on a clock signal, and when the vehicle vibrates, a control operation can be performed to display the image on one display device. Therefore, images can be displayed without distortion.

[0102] Furthermore, various effects directly or indirectly understood through the present disclosure can be provided.

[0103] Although the present disclosure has been described above with reference to exemplary embodiments and the accompanying drawings, the present disclosure is not limited thereto, but various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the present disclosure as claimed in the appended claims.

[0104] Therefore, the embodiments of the present disclosure are provided to explain the spirit and scope of the present disclosure rather than to limit the spirit and scope of the present disclosure. Therefore, the spirit and scope of the present disclosure are not limited by the embodiments. The scope of the present disclosure should be interpreted on the basis of the appended claims, and all technical concepts that fall within the scope equivalent to the claims should be included in the scope of the present disclosure.
