[0029] Fig. Figure 1 is a block diagram showing a display device of a vehicle according to an embodiment of the present disclosure.

[0030] Referring to Fig. 1 According to one embodiment of the present disclosure, a display device 100 of a vehicle may comprise a first display device 110, a second display device 120, a first control 130 and a second control 140.

[0031] The first display device 110 can display vehicle-related information. The first display device 110 can, for example, include a higher-resolution LED, an LED array, an LED matrix, and / or a digital display device (DMD).

[0032] The first display device 110 can display an image containing vehicle-related information in a first display area. For example, the first display device 110 can display an image that includes the first vehicle-related information and the second vehicle-related information. As another example, the first information and the second information can include at least one of the following: the vehicle's direction of travel, the vehicle's speed, the vehicle's route, the speed limit on the road, the remaining distance to a destination, or information about an obstacle, but the present disclosure is not limited to these.

[0033] According to one embodiment, the first display device 110 can be contained in a light. For example, the first display device 110 can be contained in a left-hand light of the vehicle.

[0034] The second display unit 120 can display vehicle-related information. The second display unit 120 can, for example, include a higher-resolution LED, an LED array, an LED matrix, and / or a digital display device (DMD).

[0035] The second display device 120 can display an image containing vehicle-related information in a second display area. For example, the second display device 120 can display an image that includes the first vehicle-related information and the second vehicle-related information. As another example, the first information and the second information can include at least one of the following: the vehicle's direction of travel, the vehicle's speed, the vehicle's route, the speed limit on the road, the remaining distance to a destination, or information about an obstacle, but the present disclosure is not limited to these.

[0036] According to one embodiment, the second display device 120 can be contained in a light. The second display device 120 can, for example, be contained in a left-hand light of the vehicle.

[0037] The first display unit 110 and the second display unit 120 can display the image simultaneously. For example, the first display unit 110 can display an image that includes the first vehicle-related information, and the second display unit 120 can display an image that includes the second vehicle-related information.

[0038] According to another embodiment, only one of the display devices, either the first display device 110 or the second display device 120, can display an image. For example, the first display device 110 can include an image that encompasses both the first and second vehicle-related information, while the second display device 120 cannot display an image. Since in this case only the first display device 110 displays the image, the image can be displayed without distortion, even in the event of vibration or impact of the vehicle.

[0039] The first control unit 130 can acquire information about the vehicle's behavior (i.e., vehicle behavior information). For example, vehicle behavior information can include information about the vehicle's vibration (i.e., vehicle vibration information) and / or information about the vehicle's expected vibration (i.e., vehicle vibration prediction information). For example, vehicle behavior information can include at least one of the following: information about the vehicle's collision, information about the impact on the vehicle, information about the vehicle's expected collision, or information about the vehicle's expected impact.

[0040] The first controller 130 can control the operation of the first display device 110 based on the information it receives about the vehicle's behavior. For example, the first controller 130 can control whether an image is displayed on the first display device 110, and it can control the direction, angle, position, height, area, brightness, luminance, color, time, and / or other information for displaying an image on the first display device 110. For example, information about the expected vibration of the vehicle can be received based on the vehicle's trajectory, position, or traffic information.

[0041] The second control unit 140 can acquire information about the vehicle's behavior. For example, this information can include information about the vehicle's vibration and / or information about the vehicle's expected vibration. The vehicle's behavior information can include, for example, at least one of the following: information about the vehicle's collision, information about the impact on the vehicle, information about the vehicle's expected collision, or information about the vehicle's expected impact.

[0042] The second controller 140 can control the operation of the second display device 120 based on the acquired information about the vehicle's behavior. For example, the second controller 140 can control whether an image is displayed via the second display device 120, and it can control a direction, angle, position, height, area, brightness, luminance, color, time, and / or information for displaying an image via the second display device 120.

[0043] Fig. Figure 2 is a view showing two modes of displaying an image by a display device of a vehicle according to an embodiment of the present disclosure.

[0044] As in Fig. As shown in Figure 2, according to one embodiment of the present disclosure, the display device 100 of the vehicle can display an image in front of the vehicle in two modes.

[0045] “Mode 1” is a mode in which an image is displayed only via the first display device 110, which is contained in the display device 100 of the vehicle.

[0046] “Mode 2” is a mode in which an image is displayed via both the first display unit 110 and the second display unit 120, which are contained in the display device 100 of the vehicle.

[0047] Regarding "Mode 1" and "Mode 2," there is no difference between Area 1 for displaying an image when only the first display unit 110 is showing an image, and Area 2 for displaying an image when both the first display unit 110 and the second display unit 120 are showing an image. In other words, even if only the first display unit 110 is showing the image, the image can still display vehicle-related information for the driver.

[0048] Although this in Fig. If display 2 is not shown, "Mode 3" is possible, i.e., a mode for displaying an image only via the second display unit 120. When the image is displayed in "Mode 3," the driver can see an image with vehicle-related information similar to the comparison result between "Mode 1" and "Mode 2." In other words, the vehicle's display unit 100 can only display an image via one of the two display units, either display unit 110 or display unit 120. Even if the image is displayed via only one display unit, there is no difference in effect compared to the case where the image is displayed via both the first display unit 110 and the second display unit 120.

[0049] Fig. Figure 3 is a view showing that a display device of a vehicle according to an embodiment of the present disclosure displays an image. Although Fig. Figure 3 shows that the first display device 110 is positioned on the left side of the vehicle 10 and the second display device 120 is positioned on the right side of the vehicle 10; the present disclosure is not limited thereto.

[0050] Referring to Fig. 3. According to one embodiment of the present disclosure, the vehicle's display device 100 can display an image via a display unit. For example, the first display unit 110 can contain an image, and the second display unit 120 can not display an image.

[0051] The first controller 130 can control the first display unit 110 to display an image. For example, the first controller 130 can control only the first display unit 110 to display the image by sending a control signal to the second controller 140 that controls the second display unit 120 so that it does not display the image. In another example, both the first controller 130 and the second controller 140 can determine that only the first display unit 110 displays an image; the first controller 130 can control the first display unit 110 to display an image, and the second controller 140 can control the second display unit 120 so that it does not display the image.

[0052] According to one embodiment, the display device 100 of the vehicle 10 can display an image via the second display device 120 and not display the image via the first display device 110. In this case, the second controller 140 can control the second display device 120 to display the image, and the first controller 130 can control the first display device 110 to not display the image.

[0053] Fig. Figure 4 is a view showing two modes of alternating display of images by a display device of a vehicle according to an embodiment of the present disclosure. Although Fig. Figure 4 shows that the first display device 110 is positioned on the left side of the vehicle 10 and the second display device 120 is positioned on the right side of the vehicle 10; the present disclosure is not limited thereto.

[0054] The first controller 130 and the second controller 140 can control the first display unit 110 and the second display unit 120, respectively, so that they display images alternately. For example, the alternating display of the image can refer to the image being displayed only via one display unit, either the first display unit 110 or the second display unit 120.

[0055] According to one embodiment, the first controller 130 can select a display device that shows an image from either the first display device 110 or the second display device 120. For example, based on information about the vehicle's behavior, the first controller 130 can select a display device that shows an image from either the first display device 110 or the second display device 120. According to one embodiment, the first controller 130 can configure the first display device 110 to show an image and configure the second display device 120 not to show an image in a default state. According to another embodiment, the second controller 140 can select a display device that shows an image from either the first display device 110 or the second display device 120.

[0056] The first controller 130 can transmit a control signal to the second controller 140, preventing the second controller 140 from displaying an image when the first display device 110 is displaying an image. For example, when the second controller 140 receives the control signal from the first controller 130, it can control the second display device 120 so that it does not display an image.

[0057] The first controller 130 can transmit a control signal to the second display unit 120, so that the second display unit 120 displays an image when it is determined that the first display unit 110 is not displaying an image. For example, when the control signal is received from the first controller 130, the second controller 140 can control the second display unit 120 to display the image.

[0058] According to one embodiment, the first controller 130 can determine that the first display device 110 does not display an image in at least one of the following cases: the case where a vibration is expected with respect to the first display device 110; the case where an impact is expected with respect to the first display device 110; the case where a vibration occurs with respect to the first display device 110; and the case where the vibration is expected with respect 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 can allow the second controller 140 to display an image via the second display device 120.

[0059] According to one embodiment, the first controller 130 can transmit a control signal to the second controller 140 so that the image is displayed via the second display device 120 if it is more effective to display the image via the second display device, even if the display of the image via the first display device 110 has not failed. For example, if the vehicle 10 is rotating in a direction in which the second display device 120 is located, the first controller 130 can determine that it is more effective for the second display device 120 to display an image, either because the second display device 120 displays the image more consistently than the first display device 110, or because part of the first display device 110 has failed.

[0060] According to one 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 to alternately display an image, based on information about the behavior, which includes vehicle-related information in order to provide the driver with an image that has no image distortion and is adapted to a vehicle situation.

[0061] Fig. Figure 5 is a view showing that a vehicle's display device simultaneously displays an image.

[0062] Referring to Fig. 5. The display device 100 of the vehicle 10 can simultaneously display images via 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 display the images simultaneously based on information about the behavior of the vehicle 10.

[0063] When the images are displayed simultaneously, the display device 100 of the vehicle 10 enables the first display device 110 and the second display device 120 to be synchronized with each other for displaying images, thereby reducing image distortion. For this purpose, the first controller 130 can generate a clock signal and transmit 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 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 clock signal received from the first controller 130. In other words, the second controller 140 can be synchronized to display an image based on the received clock signal.According to one embodiment, the second controller 140 can generate a clock signal and transmit the clock signal to the first controller 130 in order to be synchronized with the first controller 130 so that the image is displayed.

[0064] Referring to Fig. 6. The display device 100 of the vehicle 10 can perform a control operation such that a display device shows an image when the images are displayed simultaneously and when specific information is acquired. The specific information may be, for example, information about the behavior of the vehicle 10. The information about the behavior of the vehicle 10 may include at least one of the following: information about the vibration of the vehicle 10, information about the vibration expected by the vehicle 10, information about the collision of the vehicle 10, information about the impact of the vehicle 10, and information about an expected impact of the vehicle 10.The first controller 130 can transmit a control signal to the second controller 140, preventing the second display unit 120 from displaying an image simultaneously if, based on information about the vehicle 10's behavior, it is determined that vibration of the vehicle 10 is present or expected. For example, the second controller 140 can stop the second display unit 120 from displaying the image when it receives the control signal. Since the first display unit 110 displays all images, the distortion of the displayed images can be reduced accordingly.

[0065] According to another embodiment, the first controller 130 and the second controller 140 can acquire information about the behavior of the vehicle 10. If vibration of the vehicle 10 is present or expected, the first controller 130 can control the first display device 110 to display all images, and the second controller 140 can control the second display device 120 to display no images.

[0066] Fig. Figure 7 is a flowchart showing a method for operating a vehicle display device according to an embodiment of the present disclosure.

[0067] Referring to Fig. 7 According to an embodiment of the present disclosure, the method for operating the display device 100 of the vehicle 10 may comprise controlling the operation of the first display device for displaying an image comprising first vehicle-related information and second vehicle-related information in a first display area based on the acquired information about the behavior of the vehicle (S110) and controlling the operation of the second display device for displaying an image in a second display area based on the acquired information about the behavior of the vehicle (S120).

[0068] When controlling the operation of the first display device to display the image comprising the first vehicle-related information and the second vehicle-related information in the first display area based on the acquired information about the vehicle's behavior (S110), the first controller 130 can control the operation of the first display device 110. For example, the first controller 130 can control the first display device 110 to display the image comprising the first vehicle-related information and the second vehicle-related information in the first display area.In another example, the first vehicle-related information and the second vehicle-related information may include at least one of the following: the direction of travel of the vehicle, the speed of the vehicle, the route taken by the vehicle, the speed limit on the road, the remaining distance to a destination, or information about an obstacle.

[0069] When controlling the operation of the second display device to display the image in the second display area, the second controller 140 can control the operation of the second display device 120 based on the acquired information about the vehicle's behavior (S120). For example, the second controller 140 can control the second display device 120 to display an image in the second display area.

[0070] Fig. 8 and Fig. Figure 9 are flowcharts that show in detail a method for operating a display device of a vehicle according to an embodiment of the present disclosure.

[0071] Referring to Fig. Section 8 comprises the method for operating the vehicle's display device 100 according to an embodiment of the present disclosure, the individual control of a first display device and a second display device such that the first display device and the second display device alternately display the image (S210), the transmission of a control signal to prevent the second display device from displaying the image (S220), and the transmission of the control signal such that the second display device displays an image when it is detected that the first display device is not displaying an image (S230). According to one embodiment, S210 to S230 can be in a configuration of S110 to S120. Fig. It should contain 7.

[0072] When individually controlling the first and second display units so that the first or second display unit alternately shows the image (S210), the first controller 130 and the second controller 140 can control the first display unit 110 and the second display unit 120, respectively, so that the first display unit 110 and the second display unit 120 alternately display an image. For example, if the first controller 130 controls the first display unit 110 to display an image, the second controller 140 can control the second display unit 120 so that it does not display an image. If the first controller 130 controls the first display unit 110 so that it does not display an image, the second controller 140 can control the second display unit 120 so that it displays an image.In other words, the first controller 130 and the second controller 140 can perform control operations, so that only one display unit, the first display unit 110 or the second display unit 120, displays an image.

[0073] When transmitting the control signal to prevent the second display unit from displaying the image (S220), if the first controller 130 controls the first display unit 110 to display an image, the first controller 130 can transmit the control signal to the second controller 140 so that the second display unit 120 is prevented from displaying the image. For example, the second controller 140 can control the second display unit 120 based on the control signal received from the first controller 130 so that the second display unit 120 is prevented from displaying an image. According to one embodiment, if S230 is executed, S220 cannot be executed. According to another embodiment, S220 cannot be executed if the first display unit 110 and the second display unit 120 are displaying an image simultaneously.

[0074] When transmitting the control signal so that the second display unit shows an image when it is determined that the first display unit is not showing an image (S230), the first controller 130 can transmit the control signal to the second controller 140 so that the second display unit 120 shows an image. For example, the second controller 140 can control the second display unit 120 to display an image based on the control signal received from the first controller 130. According to one embodiment, S230 cannot be executed when S220 is executed. According to another embodiment, S230 cannot be executed when the first display unit 110 and the second display unit 120 are displaying an image simultaneously.

[0075] Referring to Fig. According to one embodiment of the present disclosure, the method for operating the vehicle's display device 100 may further comprise: individually controlling a first display device and a second display device based on information about the vehicle's behavior so that images are projected simultaneously (S310); transmitting a clock signal (S320); synchronizing to display an image based on the clock signal (S330); and transmitting a control signal so that the second display device is prevented from projecting the image simultaneously when vehicle vibration is present or expected (S340). According to one embodiment, S310 to S340 may be combined in at least one of S110 to S120. Fig. It should contain 7.

[0076] The first controller 130 and the second controller 140 can control the first display unit 110 and the second display unit 120 to project images simultaneously based on information about the behavior of the vehicle 10, by individually controlling the first and second display units based on the information about the vehicle's behavior, so that images are projected simultaneously (S310). The information about the behavior of the vehicle 10 can include at least one of the following: information about the vibration of the vehicle 10, information about the expected vibration of the vehicle 10, information about the collision of the vehicle 10, information about the impact of the vehicle 10, information about the expected collision of the vehicle 10, and information about the expected impact of the vehicle 10.

[0077] The first controller 130 can generate a clock signal and can transmit the generated clock signal to the second controller 140 when transmitting the clock signal (S320).

[0078] The second controller 140 can be synchronized to display an image based on the received clock signal during synchronization (S330). For example, the first controller 130 can control the first display unit 110 to display an image based on the generated clock signal, and the second controller 140 can control the second display unit 120 to display an image based on the received clock signal, so that the first display unit 110 and the second display unit 120 are synchronized with each other to display images simultaneously.

[0079] The first controller 130 can transmit a control signal to the second controller 140 upon transmission of the control signal, preventing the second display unit 120 from simultaneously projecting an image if, based on information about the vehicle's behavior 10, it is determined that vehicle vibration is present or expected (S340). For example, the second controller 140 can control the second display unit 120 based on the received control signal so that the second display unit 120 is prevented from displaying an image, and the first display unit 110 can display all images.

[0080] Fig. Figure 10 is a view showing a vehicle according to one embodiment of the present disclosure.

[0081] According to Fig. 10. A vehicle 1000 according to an embodiment of the present disclosure may comprise a sensor 1100 and a display device 1200.

[0082] The sensor 1100 can acquire information about the vehicle 1000. For example, the sensor 1100 can acquire information about the vehicle's behavior. According to another example, the sensor 1100 can acquire at least one of the following: information about the vibration of the vehicle 1000, information about an expected vibration of the vehicle 1000, information about a collision of the vehicle 1000, information about the impact of the vehicle 1000, information about an expected collision of the vehicle, and information about an expected impact of the vehicle 1000. According to one embodiment, the sensor 1100 can include an accelerometer and / or a lidar sensor and / or a camera sensor and / or a radar sensor. The sensor 1100 can transmit the acquired information to the display device 1200.

[0083] The display device 1200 can comprise a display unit 1210 and a control unit 1220. The display device 1200 can display an image in front of the vehicle 1000. The display device 1200 can, for example, be connected to a headlight, either the left or the right headlight, of the vehicle 1000. According to another example, the display device 1200 can be contained within the headlight of the vehicle 1000.

[0084] According to one embodiment, the display device 1200 can be contained in only one of the headlights of the vehicle 1000. In other words, the display device 1200 cannot be contained in any headlight other than the one containing the display device 1200. For example, the display device 1200 can be contained in the left headlight of the vehicle 1000 and not in the right headlight of the vehicle 1000. Although Fig.Figure 10 shows that the display device 1200 can be contained in the left headlight of the vehicle 1000; however, the present disclosure is not limited to this. For example, the display device 1200 can be contained in the right headlight of the vehicle 1000. In this case, the display device 1200 cannot be contained in the left headlight.

[0085] For example, the display unit 1210 can show an image that includes the first vehicle-related information and the second vehicle-related information. In another example, the first vehicle-related information and the second vehicle-related information can include at least one of the following: the vehicle's direction of travel, the vehicle's speed, the vehicle's route, the speed limit on the road, the remaining distance to a destination, or information about an obstacle.

[0086] The controller 1220 can control the operation of the display unit 1210. For example, the controller 1220 can control the display unit 1210 based on information about the vehicle's behavior so that it displays an image.

[0087] According to one embodiment, in the vehicle 1000, the indicator device 1200 cannot be mounted in any headlight other than the headlight with the indicator device 1200, and the headlight with the indicator device 1200 can be operated as a dummy. In this case, providing the headlight with the indicator device 1200 as a dummy reduces the manufacturing costs of the vehicle 1000.

[0088] According to one embodiment of the present disclosure, since the display is controlled based on behavioral information of the vehicle, the image can be output without distortion in the vehicle's display device, even if vibration and / or impact occur in the vehicle.

[0089] According to one embodiment of the present disclosure, the vehicle's display device can perform a control operation such that images are displayed alternately by opposing display devices. Accordingly, the images can be displayed effectively depending on the vehicle's driving situation.

[0090] According to one embodiment of the present disclosure, the vehicle's display device can, based on a clock signal, perform a synchronization to display the images when images are simultaneously displayed via opposing display devices, and can perform a control operation to display an image via a display device when the vehicle vibrates. Accordingly, the image can be displayed without distortion.

[0091] Furthermore, a variety of effects can be provided directly or indirectly through this disclosure.

[0092] Although the present disclosure has been described with reference to exemplary embodiments and the accompanying drawings, the present disclosure is not limited thereto, but can be modified and altered in various ways by those skilled in the art who are knowledgeable in the field of the present disclosure without departing from the spirit and scope of the present disclosure claimed in the following claims.
