The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0023] The information display device 100 provided in this application is described in detail below, taking the application of the information display device 100 to a vehicle 1000 as an example.

[0024] Please refer to Figures 1 and 2. An embodiment of the present application provides an information display device 100, which is applied to a vehicle 1000. The vehicle 1000 includes an information display component 200. The information display device 100 includes a projection device 20. The projection device 20 is used to project projection light to the information display component 200 to display information on the information display component 200.

[0025] Among them, the information displayed by the information display component 200 can be at least one of the operating condition information of the vehicle 1000 (such as important information such as the braking operation, operating status, operating speed, turn instructions, etc. of the vehicle 1000), traffic prompt information based on the surrounding environment of the vehicle 1000 (such as displaying "give way to pedestrians" when the light is red), driving warning information of the vehicle 1000 (such as issuing "please keep distance from the vehicle behind" when it is detected that the vehicle behind is too close), and user display information provided by a terminal device connected to the vehicle 1000 (such as custom display information manually edited by the user, such as "I am single").

[0026] The information displayed by the information display component 200 may include the working condition information of the vehicle 1000 (such as the braking operation, running state, running speed, turning instructions and other important information of the vehicle 1000); or the information displayed by the information display component 200 may include the working condition information of the vehicle 1000 (such as the braking operation, running state, running speed, turning instructions and other important information of the vehicle 1000), traffic prompt information based on the surrounding environment of the vehicle 1000 (such as displaying "yield to pedestrians" when the light is red); or the information displayed by the information display component 200 may be the vehicle The operating condition information of vehicle 1000 (such as important information such as braking operation, operating status, operating speed, turn instructions of vehicle 1000), traffic prompt information based on the surrounding environment of vehicle 1000 (such as displaying "give way to pedestrians" when the light is red), driving warning information of vehicle 1000 (such as issuing "please keep distance from the vehicle behind" when it is detected that the vehicle behind is too close), and user display information provided by the terminal device connected to the vehicle 1000 for communication (such as custom display information manually edited by the user, such as "I am single"), are not limited in this application and are not listed here one by one.

[0027] The information display component 200 can be a component on the vehicle 1000 that can display information so that other traffic participants around the vehicle 1000 can see the displayed information. It can be, for example, the windshield, window, etc. of the vehicle 1000; the projection device 20 can be a device that can project corresponding projection light according to the control information of the vehicle 1000, and project it to the information display component for information display.

[0028] Specifically, vehicle 1000 includes an information display component 200. Information display device 100 can be installed on the body of vehicle 1000. Information display device 100 includes a projection device 20. Projection device 20 is used to project light onto information display component 200 of vehicle 1000. The projection light forms text, images, etc. on information display component 200 to display the desired information. For example, if information display component 200 of vehicle 1000 is the rear windshield of vehicle 1000, when vehicle 1000 intends to slow down, projection device 20 projects light onto information display component 200, thereby forming text or images such as "Vehicle is about to slow down. Please be careful about the distance between vehicles" on the rear windshield to display the information.

[0029] In this way, the vehicle 1000 includes an information display component 200, and the information display device 100 is applied to the vehicle 1000. The projection light is projected to the information display component 200 by the projection device 20 of the information display device 100. The projection light forms text, images, etc. on the information display component 200 of the vehicle to display information. The way of displaying information is not only diversified (such as displaying information through text, images, dynamic images, etc.), but also more conspicuous, and the effect of information display is better. Other traffic participants around the vehicle 1000 can obtain the displayed information (such as turning information, parking information, etc.) in time through the information display component 200 of the vehicle 1000 (such as the windshield), and make corresponding responses in time, thereby improving driving safety.

[0030] Moreover, compared with the current projection device 20 configured for the vehicle 1000 to project information onto the ground behind or around the vehicle 1000 to provide information to the following vehicles or other surrounding traffic participants, the present application does not use the ground as the projection surface, but uses the information display component 200 of the vehicle 1000 (such as the front windshield, rear windshield, etc. of the vehicle 1000) as the projection surface. When the following vehicles or other surrounding traffic participants obtain the displayed information, they are not restricted by the distance between vehicles, the ground environment, etc., thereby improving the scene adaptability of the information display device 100.

[0031] Optionally, the information display component 200 includes at least one of a front windshield, a rear windshield and a vehicle window.

[0032] Among them, the information display component 200 may include a rear windshield; or, the information display component 200 may include a front windshield and a rear windshield; or the information display component 200 may include a front windshield, a rear windshield and a car window, etc. This application does not limit this and will not list them one by one here.

[0033] Specifically, the information display component 200 includes at least one of the front windshield, rear windshield, and window of the vehicle 1000. For example, taking the rear windshield 200 of the vehicle 1000 as the information display component 200, the projection device 20 projects projection light onto the rear windshield 200 of the vehicle 1000, forming text, images, etc. on the rear windshield 200 of the vehicle 1000, thereby displaying information. When the vehicle 1000 is parked or driving, other traffic participants around the vehicle 1000 can obtain the information displayed by the vehicle 1000 through the rear windshield 200 of the vehicle 1000.

[0034] Please refer to FIG. 2 . In some embodiments, the information display device 100 further includes a reflection device 60 . The light projected by the projection device 20 is reflected by the reflection device 60 to the information display component 200 .

[0035] The reflecting device 60 may be a device capable of reflecting the projection light so that the projection light can be emitted to the information display component 200, such as a reflective mirror.

[0036] Specifically, the information display device 100 further includes a reflecting device 60. Light projected by the projection device 20 is reflected by the reflecting device 60 toward the information display component 200, thereby forming text or images on the information display component 200. For example, referring to FIG. 2 , assuming that the information display component 200 is the rear windshield 200 of the vehicle 1000, the information display device 100 is disposed on the exterior of the vehicle 1000, and the reflecting device 60 is a reflector 60, the projection light projected by the projection device 20 of the information display device 100 is directed toward the reflector 60. The reflector 60 can reflect the projection light, and the reflected projection light is directed toward the rear windshield 200, so that the projection light can form an image on the rear windshield 200, thereby realizing information display.

[0037] Please refer to FIG. 2 . In some embodiments, the light projected by the projection device 20 passes through the information display component 200 and then is projected onto the reflection device 60 . The light is then reflected by the reflection device 60 to the information display component 200 .

[0038] Specifically, taking the information display component 200 as the rear windshield 200 of the vehicle 1000 and the reflection device 60 located inside the vehicle as an example, the light projected by the projection device 20 passes through the rear windshield 200 of the vehicle 1000, is projected onto the reflection device 60, and is then reflected to the rear windshield 200 by the reflection device 60.

[0039] In some embodiments, the information display component 200 includes a first area 201 and a second area 202. The light projected by the projection device 20 passes through the first area 201 of the information display component 200 and is then projected onto the reflection device 60, and is reflected by the reflection device 60 to the second area 202 of the information display component 200, wherein the first area is located above the second area.

[0040] Specifically, please continue to refer to Figure 2, and take the information display component 200 as a rear windshield 200, and the rear windshield 200 includes a first area 201 and a second area 202 located below the first area 201 as an example for explanation. The light projected by the projection device 20 passes through the rear windshield 200 from the first area 201 of the rear windshield 200 and is projected onto the reflecting device 60. The reflecting device 60 reflects the light to the second area 202 of the information display component 200, and forms an image or text in the second area 202 for information display, with the second area 202 serving as the projection surface.

[0041] Optionally, the reflecting device 60 is disposed inside the vehicle 1000 ; and / or the projecting device 20 is disposed outside the vehicle 1000 .

[0042] Specifically, the projection device 20 is arranged on the outside of the vehicle 1000 and projects projection light to the information display component 200 to display information on the information display component 200; or, the reflection device 60 is arranged on the inside of the vehicle 1000, and the projection device 20 is arranged on the outside of the vehicle 1000, and the projection light of the projection device 20 passes through the information display component 200 of the vehicle 1000 and enters the reflection device 60, and the reflection device 60 reflects the light to the information display component 200.

[0043] Referring to FIG. 1 and FIG. 2 , in some embodiments, the vehicle 1000 further includes a spoiler 400 disposed on the roof. The spoiler 400 is disposed near the rear end 300 , and the projection device 20 is disposed on the spoiler 400 .

[0044] Specifically, vehicle 1000 includes a spoiler 400 located on the roof of vehicle 1000 and near the rear end 300 of vehicle 1000. Spoiler 400 can reduce air resistance generated by vehicle 1000 during driving, thereby improving the driving stability of vehicle 1000. For example, referring to FIG. 2 , the information display component 200 is the rear windshield 200 of vehicle 1000, and the reflective device 60 is a reflective mirror 60. Projection device 20 is located on spoiler 400 near the rear end 300. Projection light from projection device 20 passes through first region 201 of rear windshield 200 and enters reflective mirror 60 inside the vehicle. Mirror 60 then reflects the projection light toward second region 202 of rear windshield 200.

[0045] Please refer to FIG. 3 . In some embodiments, the information display device 100 further includes an information display device 30 . The information display device 30 is disposed on the outer surface 201 of the information display component 200 .

[0046] The information display device 30 may be a device capable of displaying an image formed by projection light, such as a curtain, a projection screen, and the like.

[0047] Specifically, the information display device 100 also includes an information display device 30, which is disposed on the outer surface of the information display component 200. When the projection device 20 projects projection light toward the information display component 200, the projection light forms an image on the information display device 30 disposed on the outer surface of the information display component 200. For example, referring to FIG. 3 , the information display device 30 is a screen 30, and the information display component 200 is a rear windshield 200. The screen 30 is disposed on the rear windshield 200. When the vehicle 1000 decelerates, the projection light from the projection device 20 can be projected onto the screen 30, thereby displaying the message "Vehicle is about to decelerate, please be careful about the distance between vehicles" on the screen 30 for information display. By providing the information display device 30, information can be clearly displayed, and other traffic participants can obtain information about the vehicle 1000 in a timely manner through the information display device 30.

[0048] Referring to FIG. 2 , in some embodiments, a projection device 20 includes a light source 21 and a light modulation module 22 . The light source 21 is configured to emit light; the light modulation module 22 is configured to modulate incoming light to generate projection light.

[0049] The light source 21 may include an LED (Light Emitting Diode) 21, etc. The light modulation module 22 may be a module capable of reflecting light from different angles and focusing the light to a specific position to generate an image. For example, the light modulation module 22 may be a digital micromirror device (DMD). The DMD is a type of optical switch that uses a rotating reflector to open and close the optical switch, with an opening and closing time of the order of microseconds. When light is directed toward the reflective lens of the DMD, when the DMD is on, the light can enter the other end of the optical fiber through a symmetrical optical path. When the DMD is off, that is, the DMD's reflector produces a small rotation, the light cannot enter the other symmetrical end after reflection, thus achieving the effect of closing the optical switch.

[0050] Specifically, referring to Figures 1 and 2, the projection device 20 includes a light source 21 and a light modulation module 22. The light source 21 is configured to emit light, and the light modulation module 22 is configured to modulate the light emitted from the light source 21 and entering the light modulation module 22 to generate projection light. The generated projection light is projected toward the information display component 200 and forms a projected image on the information display component 200 for information display. In other words, the light source 21 of the projection device 20 emits light, and after the light enters the light modulation module 22, projection light is generated. The projection light forms text, images, etc. on the information display component 200 for information display. The information displayed includes the operating condition of the vehicle 1000, the road conditions ahead, and the vehicle 1000's behavioral intentions.

[0051] Optionally, the projection device also includes a shaping lens and a free curvature lens. The shaping lens is arranged between the light source 21 and the light modulation module 22, and is used to modulate the light of the light source 21 to generate parallel light. The free curvature lens is arranged between the light modulation module 22 and the information display component 200, and is used to focus the projection light.

[0052] Specifically, the light is modulated into parallel light by the shaping lens, and the parallel light is then incident on the light modulation module 22. This allows each area of ​​the light modulation module 22 to receive light of equal intensity and uniform distribution, resulting in an image with uniform brightness and color when projected. The free-curvature lens then provides focus to improve projection clarity, and the free-curvature lens also protects the light modulation module 22 from dust.

[0053] In some embodiments, the information display device 100 further includes a processor 40 , the light modulation module 22 includes a plurality of micro lenses, and the processor 40 is configured to adjust the deflection angle of each micro lens to generate projection light.

[0054] Specifically, the information display device 100 also includes a processor 40, and the light modulation module 22 (taking DMD as an example) includes multiple microlenses, and the multiple microlenses form a microlens array, such as an n*n array, etc. The processor 40 can control and adjust the deflection angle of each microlens to generate projection light directed toward the information display component 200. By controlling different deflection angles, it controls whether to generate projection light directed toward the information display component 200 of the vehicle 1000.

[0055] Optionally, the deflection angle includes a first deflection angle and a second deflection angle, and the deflection directions of the first deflection angle and the second deflection angle are opposite; when the deflection angle of the microlens is the first deflection angle, the microlens reflects light; when the deflection angle of the microlens is the second deflection angle, the microlens transmits light.

[0056] Specifically, the deflection angle of each microlens may include an initial deflection angle, a first deflection angle and a second deflection angle. When the deflection angle of the microlens is the initial deflection angle, the optical axis of the microlens is parallel to the optical axis of the light source 21, that is, the microlens does not modulate the light of the light source 21 into a projection light directed toward the information display component 200 at this time; when the deflection angle of the microlens is the first deflection angle, the light of the light source 21 enters the microlens, and the microlens reflects the light of the light source 21 to generate a projection light directed toward the information display component 200; when the deflection angle of the microlens is the second deflection angle, the light of the light source 21 enters the microlens, and the microlens transmits the light of the light source 21, and does not generate a projection light directed toward the information display component 200.

[0057] Assume that the operating state of the microlens at the initial deflection angle is designated as the "flat state," in which the microlens is considered to be non-operating; the operating state of the microlens at the first deflection angle is designated as the "on state," in which the microlens is considered to be operating and can modulate light into projection light directed toward the information display component 200; and the operating state of the microlens at the second deflection angle is designated as the "off state," in which the microlens is considered to be operating but does not generate projection light directed toward the information display component 200. Therefore, the processor 40 of the information display device can send a control signal to adjust the deflection angle of each microlens, thereby switching the operating state of the microlens between the "flat state," the "on state," or the "off state," thereby controlling whether projection light is generated toward the information display component 200, i.e., controlling whether projection is performed on the information display component 200 of the vehicle 1000.

[0058] Optionally, the first deflection angle is 12 degrees and the second deflection angle is -12 degrees; or, the first deflection angle is 10 degrees and the second deflection angle is -10 degrees.

[0059] Specifically, the first deflection angle and the second deflection angle have opposite deflection directions. Taking the initial deflection angle as the equilibrium state, the first deflection angle can be a 12-degree (12°) deflection to the left or right compared to the initial deflection angle; or, a first deflection angle that is a 10° deflection to the left or right. For example, taking a leftward deflection as a positive direction compared to the equilibrium state of the microlens as an example, if the first deflection angle is a 12° deflection to the left, denoted as 12°, the second deflection angle can be a 12° deflection to the right, denoted as -12°; if the first deflection angle is a 10° deflection to the right, denoted as 10°, the second deflection angle can be a 10° deflection to the left, denoted as -10°.

[0060] Optionally, the processor 40 is configured to control the deflection angle of each microlens to alternate between a first deflection angle and a second deflection angle at a preset frequency.

[0061] The preset frequency may be set according to the display time of the projection light on the information display component 200, etc.

[0062] Specifically, the processor 40 controls the deflection angle of each microlens to alternate between a first deflection angle and a second deflection angle at a preset frequency. By controlling the deflection angle of each microlens to be at the first deflection angle or the second deflection angle, projection light is generated or not generated. The reflected light from multiple microlenses can form a complex image in a very short time. The image formation on the retina requires a certain integration time. During this integration time, the inter-frame images can be superimposed on the retina. The human eye only perceives the superimposed image during the integration time, which is the persistence of vision characteristic of the human eye. In other words, by controlling the deflection angle of the microlens to generate or not generate projection light at a preset frequency, the brightness of the displayed information in the human eye will change based on the persistence of vision characteristic of the human eye, which can improve the visual effect. The higher the frequency of the alternating change of the deflection angle of the microlens between the first deflection angle and the second deflection angle, the higher the grayscale of the projected image. For example, by gradually increasing the flipping frequency of each microlens, the display effect of the displayed information in the human eye appears to be gradually brighter. By controlling the flipping of each microlens at a lower flipping frequency, the display effect of the displayed information in the human eye appears to be darker.

[0063] Referring to Figures 1 and 6, in some embodiments, the light modulation module 22 further includes a plurality of filters, each of which includes a plurality of regions, each of which passes light of a different wavelength band, and the filters and microlenses are arranged in a one-to-one correspondence. The processor 40 is further configured to rotate the filter so that the target region of the filter is aligned with the corresponding microlens to adjust the color of the light emitted by the filter.

[0064] The filter may be any filter such as a visible filter that can filter the wavelength of the light incident on the light modulation module 22 . For example, the filter may be a color wheel.

[0065] Specifically, the light modulation module 22 also includes multiple filters, each of which includes multiple regions. Each region transmits light of a different wavelength band, and can selectively transmit or block light of a specific wavelength band according to actual usage requirements. In addition, each region of the filter can also have its own optical properties, such as different transmittances and reflectances, thereby achieving control of light of a specific wavelength band. The filters and microlenses are set in a one-to-one correspondence. The processor 40 is also configured to rotate the filter so that the target area of ​​the filter is aligned with the corresponding microlens, thereby adjusting the color of the light emitted by the filter. The target area can be determined based on the displayed information. For example, if the filter includes a first area that turns light red after passing through, then when red projection light is required, the target area is the first area. In this way, the projection device 20 can achieve different display effects and enrich the displayed content when projecting.

[0066] Referring to Figures 1 and 6, in some embodiments, the information display device 100 also includes a register 50, which is configured to store information to be displayed. The processor 40 is also configured to rotate each filter according to the information to be displayed to adjust the color of the light emitted by each filter to generate projection light for displaying the information to be displayed.

[0067] The information to be displayed may be information that the user wants to project on the information display component 200 of the vehicle 1000 through the information display device 100 , including the information content, the color of the information content, and the like.

[0068] Specifically, the information display device 100 also includes a register 50 configured to store information to be displayed. Since the filters can selectively transmit or block light of different wavelengths, thereby generating projection light of different colors, the processor 40 can control the frequency and rotation speed of the rotation of each filter based on the information to be displayed stored in the register 50, thereby adjusting the color of the projection light emitted by each filter, thereby generating projection light that displays the information to be displayed. The information to be displayed stored in the register 50 can also be user-defined information, such as advertising information (such as investment promotion information, marriage proposal information, etc.) or driving experience information of the vehicle 1000. For example, a user can store yellow driving experience information of the vehicle 1000 in the register 50 to be displayed, such as "The owner is in the apprenticeship stage, the driving skills are poor, and any offense is apologized." The processor 40 can then control the rotation of the filters so that the information display device 100 can project the yellow driving experience information of the vehicle 1000, such as "The owner is in the apprenticeship stage, the driving skills are poor, and any offense is apologized."

[0069] Please refer to Figures 4 and 5. The present application further proposes an electronic device 500. The electronic device 500 is connected to the information display device 100. The electronic device 500 includes a controller 501. The processor 40 of the information display device 100 is integrated in the controller 501.

[0070] Specifically, referring to FIG5 , the vehicle of the present application includes an electronic device 500, an information display component 200, and an information display device 100. The electronic device 500 can be installed in the vehicle 1000. The electronic device 500 can integrate the information of the vehicle 1000 and process the information in a unified manner (such as outputting information or forwarding information, etc.). The controller 501 of the electronic device 500 transmits the processed information to the sub-controller on the vehicle 1000 through protocol transmission [such as the Transmission Control Protocol (TCP), etc.] to drive the corresponding sub-controller. For example, the controller 501 of the electronic device 500 can drive the processor 40 to control the information display device 100 to display information. In this way, not only can the length of the wiring harness of the vehicle 1000 and the number of microcontrollers (MCUs) on the vehicle 1000 be reduced, but the data processing capability of the vehicle 1000 can also be improved, with the advantages of centralization, high efficiency, and low cost.

[0071] Please refer to Figures 1 and 5. Optionally, the electronic device 500 also includes a memory 502, which is used to store information to be displayed. The information display device 100 is used to display the information to be displayed. The information to be displayed is generated based on at least one of the operating information of the vehicle 1000, the first editing information, and the second editing information, wherein the first editing information is generated based on the first editing operation received by the central control display screen of the vehicle 1000, and the second editing information is generated based on the second editing operation received by the mobile terminal 2000 that is communicatively connected to the electronic device 500.

[0072] Among them, the information to be displayed can be generated based on the operating information of vehicle 1000; or, the information to be displayed can be generated based on the operating information of vehicle 1000 and the first editing information; or, the information to be displayed can be generated based on the operating information of vehicle 1000, the first editing information and the second editing information. They are not listed one by one here, and this application does not impose any restrictions on this.

[0073] Specifically, the electronic device 500 further includes a memory 502 for storing information to be displayed. The electronic device 500 may send the information to be displayed in the memory 502 to the register 50 for storage. The controller 40 controls the information display device 100 to display the information based on the information to be displayed in the register 50. The information to be displayed may be generated based on the operating information of the vehicle 1000. For example, referring to FIG6 , the controller 501 may process information such as vehicle information received from the central control display (e.g., vehicle default settings, over-the-air (OTA) technology, user-defined information), vehicle unlocking status, autonomous driving status, engine and motor status, and multimedia personal computer (MPC) module, etc., through information interaction and other information logic processing to obtain the operating information of the vehicle 1000. The corresponding information to be displayed is generated based on the operating information. The information to be displayed may be stored in the memory 502. The controller 501 may transmit the information to be displayed to the information display device 100 via a data channel. The information display device 100 stores the information to be displayed through the register 50.

[0074] The information to be displayed may be the first editing information generated by receiving the first editing operation performed by the user on the central control display screen of the vehicle 1000. For example, the mobile terminal 2000 of the vehicle 1000 receives the first editing operation of the user, such as editing the displayed text content, text color or displayed image, etc., and generates the first editing information corresponding to the text content, text color (such as red) or displayed image edited by the user according to the first editing operation.

[0075] The information to be displayed may also be a second editing operation performed by the user on the mobile terminal 2000 that is in communication with the electronic device 500. The electronic device 500 receives the second editing operation information sent by the mobile terminal 2000 and generates second editing information. For example, the mobile terminal 2000 receives the user's second editing operation, such as editing the displayed text content, text color or displayed image, etc. The electronic device 500 communicates with the mobile terminal 2000, receives the second editing operation information, and generates second editing information corresponding to the text content, text color (such as red) or displayed image edited by the user.

[0076] It is understood that the mobile terminal 2000 and the electronic device 500 can communicate with each other via wireless means (such as wireless LAN (Wireless Fidelity, Wi-Fi) communication, Bluetooth communication, infrared communication, etc.). The communication between the mobile terminal 2000 and the electronic device 500 is not limited to the above communication means, and this application does not impose any restrictions on this.

[0077] Furthermore, if the information to be displayed needs to be modified, only the data in the memory 502 needs to be modified or updated, such as by communicating over a network to modify or update the data in the memory 502. This application does not limit the modification or update mode; for example, the data in the memory 502 can be updated via an upgrade mode such as a Controller Area Network (CAN), a high-speed CAN bus protocol (CAN with Flexible Data Rate, CAN FD), or Ethernet.

[0078] Referring to FIG. 1 , FIG. 2 and FIG. 7 , the information display method of the present application is applied to a vehicle 1000 . The vehicle 1000 includes an information display component 200 and an information display device 100 . The method includes:

[0079] Step 011 : Control the projection device 20 of the information display apparatus 100 to project projection light onto the information display component 200 , so as to display information on the information display component 200 .

[0080] Specifically, the vehicle 1000 includes an information display component 200 and an information display device 100. By controlling the projection device 20 of the information display device 100 to project projection light toward the information display component 200, the projection light forms an image on the information display component 200. The image is the content to be displayed by the information display. The way of displaying information is not only diversified (such as displaying information through text, images, dynamic images, etc.), but also more conspicuous, and the effect of information display is better. Other traffic participants around the vehicle 1000 can obtain the displayed information (such as turning information, parking information, etc.) in time through the information display component 200 of the vehicle 1000 (such as the windshield), and make corresponding responses in time, thereby improving driving safety.

[0081] Referring to FIG8 , in some embodiments, the information display method further includes:

[0082] Step 012: Obtain current operating condition information of vehicle 1000;

[0083] Step 013: Generate working condition display information based on current working condition information;

[0084] Step 011: Controlling the projection device 20 of the information display device 100 to project projection light onto the information display component 200 to display information on the information display component 200, including:

[0085] Step 0111 : Control the projection device 20 to project projection light onto the information display component 200 , so as to display working condition information on the information display component 200 .

[0086] The operating condition information of the vehicle 1000 may be information indicating the moving state of the vehicle 1000 (such as acceleration, deceleration, or turning, etc.).

[0087] Specifically, the current operating condition information of the vehicle 1000 can be obtained by acquiring information about the steering transmission system, braking system, and mobile system of the vehicle 1000. Based on the current operating condition information, operating condition display information is generated. The projection device 20 is then controlled to project light toward the information display component 200 to display the operating condition display information. For example, taking the rear windshield 200 of the vehicle 1000 as the information display component 200, the current operating condition information of the vehicle 1000 is deceleration, acquired through the braking system of the vehicle 1000. Based on this deceleration operating condition information, operating condition display information such as "The vehicle is decelerating. Please pay attention to the distance between vehicles" is generated. The projection device 20 is then controlled to project light toward the information display component 200 to display the operating condition display information such as "The vehicle is decelerating. Please pay attention to the distance between vehicles" on the rear windshield 200 of the vehicle 1000.

[0088] Referring to FIG9 , in some embodiments, the information display method further includes:

[0089] Step 014: Acquire environmental information around the vehicle 1000;

[0090] Step 015: Generate traffic prompt information based on environmental information;

[0091] Step 011: Controlling the projection device 20 of the information display device 100 to project projection light onto the information display component 200 to display information on the information display component 200, including:

[0092] Step 0112: Control the projection device 20 to project projection light onto the information display component 200 to display traffic prompt information on the information display component 200.

[0093] The environmental information around the vehicle 1000 may include location information and movement information of pedestrians, the vehicle 1000 or other traffic participants.

[0094] Specifically, environmental information surrounding the vehicle 1000, such as whether there are pedestrians passing by the vehicle 1000, can be collected through sensors on the vehicle 1000 (e.g., radar, camera, ultrasonic sensor, etc.). Traffic prompt information is then generated based on the environmental information, and the projection device 20 is controlled to project light toward the information display component 200 to display the traffic prompt information. For example, taking the rear windshield 200 of the vehicle 1000 as an example, the sensor acquires environmental information that a pedestrian is crossing the road in front of the vehicle 1000. Based on this environmental information, a traffic prompt message "yield to pedestrians" is generated, and the projection device 20 is controlled to project light toward the information display component 200 to display the traffic prompt message "yield to pedestrians" on the rear windshield 200 of the vehicle 1000, thereby alerting other traffic participants and increasing information exchange during traffic.

[0095] Referring to FIG. 10 , in some embodiments, the information display method further includes:

[0096] Step 016: Obtain the distance between the object behind the vehicle 1000 and the vehicle 1000;

[0097] Step 017: When the distance is within the preset distance range, generate a warning message;

[0098] Step 011: Controlling the projection device 20 of the information display device 100 to project projection light onto the information display component 200 to display information on the information display component 200, including:

[0099] Step 0113: Control the projection device 20 to project the projection light onto the information display component 200 to display the warning information on the information display component 200.

[0100] Among them, the object can be a traffic participant, such as a pedestrian, an animal, a vehicle 1000, etc.; the preset distance can be 1.5 meters (m), 1.3m, 1.1m, 1m, 0.9m, 0.8m, 0.5m, etc., which are not listed here one by one.

[0101] Specifically, the distance between the object behind the vehicle 1000 and the vehicle 1000 can be acquired through sensors on the vehicle 1000 (such as radar, camera, ultrasonic sensor, etc.). For example, an ultrasonic sensor can be provided on the vehicle 1000 to generate ultrasonic waves and receive echoes. The distance between the vehicle 1000 and the object behind the vehicle 1000 is calculated based on the time difference between the echoes. When the distance between the vehicle 1000 and the object behind the vehicle 1000 is within a preset distance range, a warning message is generated to warn other traffic participants, and the projection device 20 is controlled to project light toward the information display component 200 to display the warning message.

[0102] Optionally, the preset distance range includes multiple ones, and the warning information corresponding to each of the multiple preset distance ranges is different.

[0103] Specifically, by setting multiple preset distance ranges, each corresponding to a different warning message, different warnings can be issued based on the distance between vehicle 1000 and the object behind it. For example, as the maximum value of the distance range decreases, the corresponding warning message can be set to a higher grayscale, a brighter color, or a flashing light. This alerts the vehicle behind 1000, reduces the probability of traffic accidents, and improves driving safety.

[0104] For example, taking the information display component 200 as the rear windshield 200 of the vehicle 1000, the preset distance range includes two, the first preset distance range is 1m~1.2m, and the second preset distance range is 0.8m~1m. For example, the sensor continuously obtains the distance between the rear vehicle and the vehicle 1000. When the distance decreases to less than 1.2m and greater than 1m, it generates a first warning message of "The distance between the vehicles is small, please maintain a safe following distance" and controls the projection device 20 to project projection light toward the rear windshield 200, thereby displaying the first warning message to warn the rear vehicle; when the sensor obtains that the distance between the vehicles is still decreasing, until the distance decreases to less than 1m and greater than 0.8m, it generates a second warning message, which may include a flashing image of "The distance between the vehicles is small, please maintain a safe following distance!", and controls the projection device 20 to project corresponding projection light toward the rear windshield 200, thereby displaying the second warning message to warn the rear vehicle.
