[0040] The information display device 100 provided in the present application is described in detail below, taking the application of the information display device 100 to a vehicle 1000 as an example for illustration.

[0041] See also Figure 1 and Figure 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.

[0042] 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 a safe 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 for communication (such as custom display information manually edited by the user, such as "I am single").

[0043] The information displayed by the information display component 200 may include the operating information of the vehicle 1000 (such as the braking operation, running status, running speed, turn indication and other important information of the vehicle 1000); or the information displayed by the information display component 200 may include the operating information of the vehicle 1000 (such as the braking operation, running status, running speed, turn indication 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 traffic 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, etc. 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 a terminal device connected to communication with vehicle 1000 (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.

[0044] 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, and can be such as 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 to display information.

[0045] Specifically, the vehicle 1000 includes an information display component 200, and the information display device 100 can be arranged on the body of the vehicle 1000. The information display device 100 includes a projection device 20, and the projection device 20 is used to project projection light to the information display component 200 of the vehicle 1000, and the projection light forms text, images, etc. on the information display component 200 to display the information to be displayed. For example, taking the information display component 200 of the vehicle 1000 as the rear windshield of the vehicle 1000 as an example, when the vehicle 1000 wants to slow down, the projection device 20 projects the projection light to the information display component 200, so as to form text or images of "the vehicle is about to slow down, please be careful of the distance between vehicles" on the rear windshield for information display.

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.

[0047] Furthermore, 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 limited by the distance between vehicles, ground environment, etc., thereby improving the scene adaptability of the information display device 100.

[0050] Specifically, the information display component 200 includes at least one of the front windshield, rear windshield, and window of the vehicle 1000. For example, the information display component 200 is the rear windshield 200 of the vehicle 1000.

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.

[0051] See also Figure 2 In some embodiments, the information display device 100 further includes a reflection device 60 , and the light projected by the projection device 20 is reflected by the reflection device 60 to the information display component 200 .

For example, see Figure 2 Taking the information display component 200 as the rear windshield 200 of the vehicle 1000, the information display device 100 is arranged on the outside of the vehicle body 1000, and the reflection device 60 is a reflector 60 as an example, the projection light projected by the projection device 20 of the information display device 100 is directed to the reflector 60, and the reflector 60 can reflect the projection light, and the reflected projection light is directed to the rear windshield 200, so that the projection light can form an image on the rear windshield 200, thereby realizing information display.

[0054] See also Figure 2 In some embodiments, the light projected by the projection device 20 passes through the information display component 200 and then is projected to the reflection device 60 , and is reflected by the reflection device 60 to the information display component 200 .

[0055] Specifically, taking the information display component 200 as the rear windshield 200 of the vehicle 1000 and the reflection device 60 being 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 onto the rear windshield 200 by the reflection device 60.

[0056] 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 to 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.

[0057] For details, please continue to see Figure 2 , taking the information display component 200 as a rear windshield 200, the rear windshield 200 includes a first area 201 and a second area 202 located below the first area 201 as an example, 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 to the reflection device 60, the reflection 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 to display information, and the second area 202 is used as the projection surface.

[0058] Optionally, the reflection device 60 is disposed inside the vehicle 1000 ; and / or the projection device 20 is disposed outside the vehicle 1000 .

[0059] Specifically, the projection device 20 is disposed 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 disposed on the inside of the vehicle 1000, and the projection device 20 is disposed 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.

[0060] See also Figure 1 and Figure 2 In some embodiments, the vehicle 1000 further includes a spoiler 400 disposed on the roof, the spoiler 400 is disposed close to the rear end 300 , and the projection device 20 is disposed on the spoiler 400 .

[0061] Specifically, the vehicle 1000 includes a spoiler 400, which is located on the roof of the vehicle 1000 and is disposed near the rear end 300 of the vehicle 1000. The spoiler 400 can reduce the air resistance generated by the vehicle 1000 when driving and improve the driving stability of the vehicle 1000. For example, see Figure 2, taking the information display component 200 as the rear windshield 200 of the vehicle 1000 and the reflecting device 60 as the reflector 60 as an example, the projection device 20 is arranged on the spoiler 400 near the rear of the vehicle 300, and the projection light projected by the projection device 20 passes through the first area 201 of the rear windshield 200 and enters the reflector 60 in the vehicle, and the reflector 60 reflects the projection light to the second area 202 of the rear windshield 200.

[0062] See also Figure 3 In some embodiments, the information display device 100 further includes: an information display device 30 , which is disposed on the outer surface 201 of the information display component 200 .

[0063] 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.

[0064] Specifically, the information display device 100 further 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, see Figure 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 set on the rear windshield 200. When the vehicle 1000 wants to slow down, the projection light of the projection device 20 can be projected onto the screen 30, so that the words "the vehicle is about to slow down, please be careful of the distance between vehicles" are displayed on the screen 30 for information display. By setting the information display device 30, the information can be clearly displayed, and other traffic participants around can obtain the information of the vehicle 1000 in time through the information display device 30.

[0065] See also Figure 2 In some embodiments, the projection device 20 includes a light source 21 and a light modulation module 22, wherein the light source 21 is configured to emit light; and the light modulation module 22 is configured to modulate incoming light to generate projection light.

[0066] The light source 21 may include an LED light source 21 (Light Emitting Diode, LED) and the like; the light modulation module 22 may be a module that can reflect light from different angles and focus the light to a specific position to generate an image. For example, the light modulation module 22 may be a digital micromirror device (DMD). DMD is a type of optical switch that uses a rotating reflector to realize the opening and closing of the optical switch, and the opening and closing time is in the order of microseconds. The light is directed to the reflective lens of the DMD. When the DMD is turned on, the light can enter the other end of the optical fiber through a symmetrical optical path; when the DMD is turned off, that is, the reflector of the DMD produces a small rotation, the light cannot enter the other symmetrical end after reflection, and the effect of closing the optical switch is achieved.

[0067] Specifically, see Figure 1 and Figure 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. 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 projection image on the information display component 200 to display information. That is, 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 to display information. The content of the information display includes the working condition of the vehicle 1000, the road condition ahead, and the behavior intention of the vehicle 1000.

[0068] 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.

[0069] Specifically, the light is modulated into parallel light by the shaping lens, and the parallel light is injected into the light modulation module 22. Each area of ​​the light modulation module 22 can receive light of the same intensity and uniform distribution, so that the image formed by the projection light can have uniform brightness and color when projected; and the free curvature lens is used for focusing to improve the clarity of the projection, and the free curvature lens can also protect the light modulation module 22 and prevent dust.

[0070] 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.

[0071] Specifically, the information display device 100 also includes a processor 40, and the light modulation module 22 (taking DMD as an example) includes a plurality of microlenses, and the plurality of 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 a projection light directed toward the information display component 200. By controlling different deflection angles, it is controlled whether to generate a projection light directed toward the information display component 200 of the vehicle 1000.

[0072] 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.

[0073] 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.

[0074] Assume that the working state of the deflection angle of the microlens at the initial deflection angle is named "flat state", and it is considered that the microlens is not working at this time; the working state of the deflection angle of the microlens at the first deflection angle is named "on state", and it is considered that the microlens is working at this time, and the light can be modulated into a projection light directed to the information display component 200 through the microlens; the working state of the deflection angle of the microlens at the second deflection angle is named "off state", and it is considered that the microlens is working at this time, but does not generate a projection light directed to the information display component 200. Then, the processor 40 of the information display device can send a control signal to adjust the deflection angle of each microlens, and control the switching of the working state of the microlens to be "flat state", "on state" or "off state", so as to control whether to generate a projection light directed to the information display component 200, that is, control whether to project on the information display component 200 of the vehicle 1000.

[0075] 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.

[0076] Specifically, the deflection directions of the first deflection angle and the second deflection angle are opposite. Taking the initial deflection angle as the equilibrium state, the first deflection angle may be a first deflection angle that is deflected 12 degrees (12°) to the left or right compared with the initial deflection angle; or, a first deflection angle that is deflected 10° to the left or right. For example, taking the left deflection as the positive direction compared with the equilibrium state of the microlens as an example for explanation, when the first deflection angle is a deflection of 12° to the left, and the first deflection angle is recorded as 12°, the second deflection angle may be a deflection of 12° to the right, and the second deflection angle may be -12°; when the first deflection angle is a deflection of 10° to the right, and the first deflection angle is 10°, the second deflection angle may be a deflection of 10° to the left, and the second deflection angle may be -10°.

[0077] 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.

[0078] The preset frequency may be set according to the display time of the projection light on the information display component 200, etc.

[0079] Specifically, the processor 40 controls the deflection angle of each microlens to alternate between the first deflection angle and the second deflection angle at a preset frequency, and generates or does not generate projection light by controlling the deflection angle of each microlens to be the first deflection angle or the second deflection angle. The reflected light of multiple microlenses can form a complex image in a very short time; it takes a certain integration time for the image to be formed on the retina, and the inter-frame imaging can be superimposed on the retina during the integration time, and the human eye obtains the image superimposed during the integration time, that is, the visual persistence characteristic of the human eye; that is, by controlling the deflection angle of the microlens to generate or not generate projection light at a preset frequency, based on the visual persistence characteristic of the human eye, the display brightness of the display information in the human eye will change, which can improve the visual effect, and the higher the frequency of the deflection angle of the microlens alternating between the first deflection angle and the second deflection angle, the higher the grayscale of the projected image, for example, by controlling the flipping frequency of each microlens to gradually increase, the display effect of the display information in the human eye gradually becomes brighter; by controlling each microlens to flip at a lower flipping frequency, the display effect of the display information in the human eye is darker.

[0080] See also Figure 1 and Figure 6 In some embodiments, the light modulation module 22 further includes a plurality of filters, the filters include a plurality of regions, the wavelength bands of the light passing through each region are different, the filters and the microlenses are arranged in a one-to-one correspondence, and the processor 40 is further configured to rotate the filters so that the target area of ​​the filters is aligned with the corresponding microlens to adjust the color of the light emitted by the filters.

[0081] 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.

[0082] Specifically, the light modulation module 22 also includes a plurality of filters, and the filter includes a plurality of regions. The wavelengths of the light passing through each region are different, and the light of a specific wavelength band can be selectively transmitted or blocked according to the actual use requirements. In addition, each region of the filter can also have its own optical properties, such as different transmittances and reflectances, so as to achieve the control of the light of a specific wavelength band. The filters and microlenses are set in a one-to-one correspondence, and the processor 40 is also configured to rotate the filter so that the target area of ​​the filter is aligned with the corresponding microlens, so as to adjust the color of the light emitted by the filter. The target area can be determined according to the displayed information. For example, the filter includes a first area that turns the light into red light after passing through. In the case of requiring red projection light, the target area is the first area. In this way, the projection device 20 can achieve different display effects and enrich the display content when performing projection.

[0083] See also Figure 1 and Figure 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.

[0084] 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, etc.

[0085] Specifically, the information display device 100 also includes a register 50, which is configured to store information to be displayed. Since the filter can selectively transmit or block light of different wavelengths to generate projection light of different colors, the processor 40 can control the frequency and rotation speed of each filter according to the information to be displayed stored in the register 50, adjust the color of the projection light emitted by each filter, and thus generate projection light for displaying 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 information, marriage information, etc.), vehicle 1000 driving experience information, etc. For example, the user can store the yellow "the owner is in the internship stage, the driving level is poor, if there is any offense, please forgive me" vehicle 1000 driving experience information to be displayed in the register 50, and control the rotation of each filter through the processor 40, so that the information display device 100 can project the yellow "the owner is in the internship stage, the driving level is poor, if there is any offense, please forgive me" vehicle 1000 driving experience information.

[0086] See also Figure 4 and Figure 5 The present application also proposes an electronic device 500 , which is connected to the information display device 100 . The electronic device 500 includes a controller 501 , and the processor 40 of the information display device 100 is integrated in the controller 501 .

[0087] Specifically, see Figure 5 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)] 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 (Micro controller Unit, MCU) on the vehicle 1000 be reduced, but also the data processing capability of the vehicle 1000 can be improved, with the advantages of centralization, high efficiency, and low cost.

[0088] See also Figure 1 and Figure 5Optionally, 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, and 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 a first editing operation received by the central control display screen of the vehicle 1000, and the second editing information is generated based on a second editing operation received by the mobile terminal 2000 that is communicatively connected to the electronic device 500.

[0089] 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.

[0090] Specifically, the electronic device 500 also includes a memory 502, which is used to store information to be displayed. The electronic device 500 can send the information to be displayed in the memory 502 to the register 50 for storage, and the controller 40 controls the information display device 100 to display information according to the information to be displayed in the register 50. The information to be displayed can be generated by the operation information of the vehicle 1000, for example, Figure 6 The controller 501 can obtain the operation information of the vehicle 1000 after performing information logic processing such as information interaction on the vehicle information received by the central control display screen (such as the vehicle's default settings, Over The Air (OTA) technology, user-defined information), the vehicle's unlocking status, automatic driving status, engine and motor status, and multimedia personal computer module (MPC module), and generate corresponding information to be displayed based on the operation information. The information to be displayed can be stored in the memory 502. The controller 501 can transmit the information to be displayed to the information display device 100 through the data channel, and the information display device 100 saves the information to be displayed through the register 50.

[0091] The information to be displayed may be first editing information generated by receiving a first editing operation performed by a 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, and generates 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.

[0092] The information to be displayed may also be a second editing operation performed by the user on the mobile terminal 2000 that is communicatively connected to 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.

[0093] It is understood that the mobile terminal 2000 and the electronic device 500 can communicate wirelessly (such as wireless LAN (Wireless Fidelity, wifi) 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 methods, and this application does not limit this.

[0094] In addition, when the information to be displayed needs to be changed, only the data in the memory 502 needs to be changed or updated, such as by communicating through a network to change or update the data in the memory 502. The present application does not limit the change or update mode, for example, the data in the memory 502 can be updated through an update mode such as a Controller Area Network (CAN), a high-speed CAN bus protocol (CAN with Flexible Data Rate, CAN FD) or Ethernet.

[0095] See also Figure 1 , Figure 2 and Figure 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, and the method includes:

[0096] Step 011 : Control the projection device 20 of the information display equipment 100 to project projection light to the information display component 200 , so as to display information on the information display component 200 .

[0097] Specifically, the vehicle 1000 includes an information display component 200 and an information display device 100. The projection light is projected toward the information display component 200 by controlling the projection device 20 of the information display device 100. 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.

[0098] See also Figure 8 In some embodiments, the information display method further includes:

[0099] Step 012: Obtain current operating condition information of vehicle 1000;

[0100] Step 013: Generate working condition display information based on current working condition information;

[0101] Step 011: Control the projection device 20 of the information display device 100 to project projection light to the information display component 200 to display information on the information display component 200, including:

[0102] Step 0111: Control the projection device 20 to project projection light to the information display component 200 to display working condition information on the information display component 200.

[0103] 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.).

[0104] Specifically, the current working condition information of the vehicle 1000 can be obtained by obtaining information of the steering transmission system, the braking system, the mobile system, etc. of the vehicle 1000, and the working condition display information can be generated based on the current working condition information, and then the projection device 20 can be controlled to project projection light toward the information display component 200 to display the working condition display information. For example, taking the information display component 200 as the rear windshield 200 of the vehicle 1000 as an example, the current working condition information of the vehicle 1000 obtained through the braking system of the vehicle 1000 is deceleration, and the working condition display information of "the vehicle is decelerating, please pay attention to the distance between vehicles" is generated according to the working condition information of deceleration, and then the projection device 20 can be controlled to project projection light toward the information display component 200 to display the working condition display information of "the vehicle is decelerating, please pay attention to the distance between vehicles" on the rear windshield 200 of the vehicle 1000.

[0105] See also Fig. 9In some embodiments, the information display method further includes:

[0106] Step 014: Obtaining environmental information around the vehicle 1000;

[0107] Step 015: Generate traffic prompt information based on environmental information;

[0108] Step 011: Control the projection device 20 of the information display device 100 to project projection light to the information display component 200 to display information on the information display component 200, including:

[0109] 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.

[0110] The environmental information around the vehicle 1000 may include location information and movement information of pedestrians, the vehicle 1000 or other traffic participants.

[0111] Specifically, environmental information around the vehicle 1000, such as whether there are pedestrians passing by the vehicle 1000, can be collected through sensors (such as radar, camera, ultrasonic sensor, etc.) on the vehicle 1000, and then traffic prompt information is generated based on the environmental information, and the projection device 20 is controlled to project projection 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 the information display component 200, environmental information that there are pedestrians crossing the road in front of the vehicle 1000 is obtained through the sensor, and traffic prompt information of "give way to pedestrians" is generated based on this environmental information, and the projection device 20 is controlled to project projection light toward the information display component 200 to display the traffic prompt information of "give way to pedestrians" on the rear windshield 200 of the vehicle 1000, reminding other traffic participants around and increasing information interaction during the traffic process.

[0112] See also Fig.10 In some embodiments, the information display method further includes:

[0113] Step 016: Obtain the distance between the object behind the vehicle 1000 and the vehicle 1000;

[0114] Step 017: When the distance is within a preset distance range, generating a warning message;

[0115] Step 011: Control the projection device 20 of the information display device 100 to project projection light to the information display component 200 to display information on the information display component 200, including:

[0116] Step 0113: Control the projection device 20 to project projection light to the information display component 200 to display warning information on the information display component 200.

[0117] 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.

[0118] Specifically, the distance between the object behind the vehicle 1000 and the vehicle 1000 can be obtained through sensors (such as radar, camera, ultrasonic sensor, etc.) on the vehicle 1000. For example, an ultrasonic sensor can be set on the vehicle 1000, and ultrasonic waves are generated and echoes are received by the ultrasonic sensor. The distance between the vehicle 1000 and the object behind the vehicle 1000 is calculated based on the time difference of 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 around, and then the projection device 20 is controlled to project projection light toward the information display component 200 to display the warning message.

[0119] Optionally, the preset distance range includes multiple ones, and the warning information corresponding to each of the multiple preset distance ranges is different from each other.

[0120] Specifically, by setting a plurality of preset distance ranges, each preset distance range corresponds to different warning information, and different warnings are made according to the distance between the vehicle 1000 and the object behind. For example, when the maximum value of the distance range is smaller, the grayscale of the corresponding warning information is set to be larger, the color of the warning information is set to be brighter, or the projection light of the warning information is set to flash, etc., so as to warn the rear vehicle 1000, reduce the probability of traffic accidents, and improve driving safety.

[0121] For example, taking the information display component 200 as the rear windshield 200 of the vehicle 1000, and the preset distance ranges include two, the first preset distance range is 1m to 1.2m, and the second preset distance range is 0.8m to 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, a first warning message of "the distance between the vehicles is small, please maintain a safe following distance" is generated, and the projection device 20 is controlled 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, a second warning message is generated, and the second warning message may include a flashing image of "the distance between the vehicles is small, please maintain a safe following distance!", and the projection device 20 is controlled to project corresponding projection light toward the rear windshield 200, thereby displaying the second warning message to warn the rear vehicle.
