Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The following describes an exemplary vehicle-mounted LED display system provided in the present application with reference to the accompanying drawings.

The vehicle-mounted LED display system provided by the application may include the vehicle-mounted module 1 and the LED display panel 301 shown in fig. 1, where the vehicle-mounted module 1 is electrically connected with the LED display panel 301, and the LED display panel 301 may perform image display according to control of the vehicle-mounted module 1. For example, the vehicle module 1 may control the LED display panel 301 to display a corresponding animation according to the running state of the vehicle. For example, when braking, the LED display panel 301 is controlled to display a corresponding braking animation, and when turning, the LED display panel 301 is controlled to display a corresponding turning animation, and so on.

Alternatively, the vehicle-mounted LED display system may include one LED display panel 301, and may also include at least one group of LED display panels 301. Each group of LED display panels 301 includes a plurality of LED display panels 301 spliced to each other. In the embodiment of the present application, each group of LED display panels 301 may set the number of LED display panels 301 and the splice shape according to the setting position.

For example, the LED display panel may be provided outside the vehicle instead of a conventional lamp. The lamps in different positions may be replaced by a set of LED display panels 301. For example, when a group of LED display panels 301 needs to be provided at the tail portion as the tail light, as shown in fig. 2, a plurality of LED display panels 301 may be assembled in sequence into an arc shape to constitute the tail light 3.

It will be appreciated that the lamps at different positions are implemented by the spliced plurality of LED display panels, so that the lamps at different positions can implement high-resolution image display, for example, the transverse direction of the taillight 3 can reach more than 1000 pixels, and the longitudinal direction can reach more than 50 pixels. Therefore, the vehicle-mounted LED display system of the vehicle display system can indicate the vehicle lamp through the richer and higher-recognition-degree pictures.

Alternatively, each group of LED display panels 301 can be spliced in sequence to form a car lamp in a serial assembly mode, so that when the car lamp works, the current of each LED display panel 301 is equal, and the overall display uniformity of the car lamp is ensured.

In some embodiments, the number of groups of LED display panels 301 may be determined according to the number of lamps that need to be provided on the vehicle. For example, as shown in fig. 3, the in-vehicle LED display system may include a set of LED display panels 301, the set of LED display panels 301 constituting the taillight 3 of the vehicle. The taillight 3 can display not only the information that the original taillight can display by means of animation, but also more picture information, for example: the car is provided with child reminding pictures or text information, novice driving reminding information, front road conditions information and the like. In addition, the display area of the LED display panel 301 provided by the present application is larger than that of the tail lamp, so that the rear vehicle can clearly know the condition of the front vehicle and other road condition information, and the accident rate is reduced to a certain extent.

Further, when the emergency needs to be braked, the existing automobile tail lamp can only present a braking state, the rear automobile can only know that the front automobile is in the braking state through the automobile tail lamp of the front automobile and cannot know other information, and the LED display panel 301 provided by the application can also display key information, such as information of emergency, emergency braking and the like, under the control of the automobile machine module 1 on the basis of displaying the braking state, so that the rear automobile can clearly know the braking reason and process the information in time, and the accident rate is reduced.

According to the vehicle-mounted LED display system, vehicle condition information (such as the running state of a vehicle, the front vehicle condition, the vehicle internal state and the like) can be displayed in an image mode based on the vehicle-to-machine signal, so that a richer and more flexible vehicle condition display effect is achieved. In addition, the vehicle-mounted LED display system includes at least one group of LED display panels 301, and each group of LED display panels 301 further includes a plurality of LED display panels 301 spliced with each other, so that high-resolution image display can be realized. Therefore, the vehicle-mounted LED display system provided by the application can display vehicle condition information through the richer and higher-recognition-degree pictures.

In one example, the in-vehicle LED display system may include two sets of LED display panels 301, and the two sets of LED display panels 301 may be disposed at the rear and front of the vehicle, respectively, or at the sides of the vehicle. For example, a group of LED display panels 301 is provided in the front of the vehicle instead of the original headlight, and a group of LED display panels 301 is provided in the rear of the vehicle instead of the original taillight. The setting positions and the number of the LED display panels 301 may be installed based on actual use situations, and the present application is not particularly limited.

In this embodiment of the present application, the vehicle-mounted LED display system may control the LED display panel 301 to display images in a centralized control manner, that is, as in the vehicle-mounted LED display system shown in fig. 1, the vehicle module 1 may directly send corresponding first display data to the LED display panel 301.

In another embodiment, the vehicle-mounted LED display system may further control the LED display panel 301 to display images in a distributed control manner. For example, as shown in fig. 4, the vehicle-mounted LED display system may further include a main control module 2. The vehicle machine module 1 sends a vehicle machine signal to the main control module 2, the main control module 2 can generate first display data corresponding to the LED display panel 301 according to the vehicle machine signal, the first display data is sent to the corresponding LED display panel 301, and the LED display panel 301 can display images according to the received first display data.

The vehicle control signal may be a vehicle control signal, i.e., a control signal for indicating a vehicle state, for example, a control signal generated at the time of braking, a control signal generated at the time of steering, a control signal for indicating a speed, a control signal for indicating a vehicle interior state (for example, whether a child is present, whether a novice driver is present, etc.), or the like. The vehicle signals can also be vehicle video signals, such as videos, images, advertisements, front road conditions and the like which the vehicle owners want to share.

Illustratively, the vehicle signal is a control signal for driving by a novice driver, and the vehicle module 1 includes a central control screen (i.e., a central control screen installed on an accessory of a driving seat) for human-computer interaction, where controls of various Application programs (apps) installed in the vehicle module 1 are displayed on the central control screen. After a user clicks a control related to novice driving displayed on a control screen, the car machine module 1 receives a control signal of novice driving and sends the control signal to the main control module 2, the main control module 2 can generate display data according to the control signal of novice driving and send the display data to the LED display panel 301, and the LED display panel 301 finally displays a character image of 'novice driving, please keep the car distance', so that surrounding pedestrians and drivers are prompted in a more straight-white mode, and the car is currently in novice driving, please cooperate to give way.

The vehicle-mounted signal is the front road condition information, after the user clicks the control of "sharing the front road condition" on the central control screen, the vehicle-mounted module 1 transmits the video data shot by the front camera to the main control module 2 in real time, the main control module 2 can generate display data according to the received video data and send the display data to the LED display panel 301, and the LED display panel 301 finally displays the image related to the road condition information, so that the rear vehicle front road condition can be informed in a more visual manner.

In one embodiment, the main control module 2 may include a control chip 201 and a deserializer 202 as shown in fig. 5. The deserializer 202 is connected to the vehicle-mounted module 1, and the deserializer 202 is configured to decode the vehicle-mounted signal into a Low-voltage differential signal (Low-Voltage Differential Signaling, LVDS) and send the LVDS to the control chip 201, and the control chip 201 may generate first display data corresponding to each LED display panel 301 according to the LVDS of the received vehicle-mounted signal and send the first display data to the corresponding LED display panel 301.

For example, the deserializer 202 may be a deserializer having a bidirectional control channel, such as DS90UB928, DS90UB927, so that the control chip 201 may receive the vehicle signal from the vehicle module 1, and may send a return signal to the vehicle module 1, so as to implement bidirectional transmission of the signal.

The control chip 201 may be a field programmable gate array (field programmable gated array, FPGA).

Optionally, in order to reduce the pin count and the track count between the master control module 2 and the vehicle machine module 1, the vehicle machine module 1 may be connected to the deserializer 202 through a flat panel display Link (Flat panel display Link III, FPD-Link III) serial bus, which reduces the pin count between the two and increases the communication data rate.

Alternatively, a high-speed data connector may be provided on the deserializer 202 for connecting to the FPD-Link III serial bus. For example, HD1-X-RM-102, HD1-4X-SF-101, etc.

In one example, the main control module 2 may further include a storage part 203 as shown in fig. 6, and the storage part 203 stores therein the topology of the plurality of LED display panels 301 and preset image data. By way of example, the preset image data may include image data related to a brake animation, a steering animation, a new hand driving animation, a start-up animation, and the present application is not particularly limited.

Alternatively, as shown in fig. 7, the storage unit 203 may include a first storage sub-unit 2031 and a second storage sub-unit 2032. The first storage sub-component 2031 may store an operation program of the vehicle-mounted LED display system, a system routing manner, and a topology structure of the plurality of LED display panels 301. The second storage sub-section 2032 may store preset image data. It should be noted that, when each group of LED display panels 301 includes a plurality of LED display panels 301, the topology herein may refer to connection manners and wirings between the respective light beads 3013 in the plurality of LED display panels 301.

The second storage sub-unit 2032 may be, for example, a Double Data Rate (DDR) memory.

The preset image data includes a plurality of target image data corresponding to different vehicle signals. For example, in one example, the vehicle control signal may be a vehicle control signal, which may be a signal indicating a vehicle state. For example, the vehicle-mounted module 1 sends a vehicle-mounted control signal to the main control module 2, and the main control module 2 determines target image data corresponding to the vehicle-mounted control signal from the pre-stored image data according to the vehicle-mounted control signal, and generates first display data corresponding to each LED display panel 301 according to the topology structure of the LED display panels 301 and the target image data.

For example, when the user wants to display a reminder of a child in the vehicle, the user may click on a corresponding app control in the in-vehicle control screen, after detecting the user instruction, the vehicle module 1 sends a vehicle control signal for indicating that the child is in the vehicle to the deserializer 202, the deserializer 202 converts the vehicle control signal into LVDS and sends the LVDS to the control chip 201, the control chip 201 determines, according to the LVDS of the vehicle control signal, target image data corresponding to the vehicle control signal (that is, displays a reminder image/video of the child in the vehicle) from the second storage subcomponent 2032, and then generates, according to the topology structures of the plurality of LED display panels 301 stored in the first storage subcomponent 2031 and the target image data, first display data corresponding to each LED display panel 301 respectively is sent to each group of LED display panels 301, and the LED display panels 301 can display "the image/video information of the child in the vehicle".

It should be noted that, in the process of generating the first display data according to the topology structure and the target image data, the control chip 201 may perform Gamma conversion, image torsion, image correction and other processes on the target image data, and generate the first display data for controlling the LED display panel 301 to perform image display according to the topology structure on the processed image data.

For example, the storage unit 203 may store display data related to the startup animation, after the vehicle is started, the vehicle engine module 1 sends a vehicle engine control signal for indicating the start of the vehicle to the master control module 2, the deserializer 202 converts the vehicle engine control signal into LVDS and sends the LVDS to the control chip 201, the control chip 201 obtains the startup animation from the second storage sub-unit 2032 according to the LVDS of the vehicle engine control signal, and then performs Gamma conversion, image torsion, image correction and other processes on the startup animation according to the topology structures of the LED display panels 301, so as to generate first display data corresponding to each LED display panel 301, and the LED display panels 301 may display video information of the startup animation.

In another example, the vehicle module 1 may also directly send video/image information to the main control module 2, i.e. the vehicle signal may be a vehicle video signal. For example, the vehicle-mounted module 1 sends a vehicle-mounted video signal to the main control module 2, and the main control module 2 generates first display data corresponding to each LED display panel 301 according to the topology structures of the LED display panels 301 and the vehicle-mounted video signal.

For example, when it is required to display the front road condition to the rear vehicle, the user may click on an app control for collecting road condition information on a central control screen in the vehicle, the vehicle machine system 1 collects a road condition video through a camera, and sends the road condition video to the decoder 202 through an FPD-Link serial bus, the decoder 202 converts the road condition video into LVDS and sends the LVDS to the control chip 201, the control chip 201 performs Gamma conversion, image torsion, image correction and other processing on the LVDS of the road condition video according to the topology structure stored in the first storage sub-component 2031, and generates first display data corresponding to each LED display panel 301 respectively and sends the first display data to each group of LED display panels 301, and the LED display panels 301 may synchronously display the front road condition video.

In an example, as shown in fig. 8, the main control module 2 provided in the present application may further include an interface component 204, where the interface component 204 and the control chip 201 may be externally connected with a debugging device (i.e. a device for debugging a vehicle-mounted LED display system, where debugging software is running), so that a user may debug a display function of the vehicle-mounted LED display system through the externally connected debugging device at any time. That is, after the interface unit 204 is connected to the debugging device, the debugging device sends a debugging signal to the main control module 2, the main control module 2 can control at least one group of LED display panels 301 to display images according to the debugging signal, and a user can debug functions of the vehicle-mounted LED display system according to the image display state of the LED display panels 301.

Illustratively, the external debug device may be: smart screens, cell phones, automobile recorders, ultra-mobile personal computers (ultra-mobile personal computer, UMPC), etc.

By way of example, the interface component 204 can be a Type-C interface, a universal serial bus (Universal Serial Bus, USB) interface, or the like.

In one example, as shown in fig. 8, the main control module 2 may further include a sensor 205, where the sensor 205 and the control chip 201, and the sensor 205 is used to monitor an operation state of the vehicle LED display system. The sensor 205 may include one or more of a temperature sensor, a pressure sensor, a voltage sensor, and the like, and is capable of detecting data such as temperature, pressure, voltage, and the like of the vehicle-mounted LED display system.

For example, the sensor 205 includes a temperature sensor for detecting the temperature of the onboard LED display system. The main control module 2 may detect whether the temperature of the vehicle-mounted LED display system exceeds a preset threshold, and if the temperature of the vehicle-mounted LED display system exceeds the preset threshold, in order to avoid burning out the LED display panel 301, the main control module 2 may start a thermal protection function, that is, control the LED display panel 301 to stop displaying images.

Optionally, the main control module 2 may also transmit the data detected by the detection sensor 205 back to the vehicle machine module 1 for the user to evaluate whether the running state of the vehicle-mounted LED display system is normal. For example, the user may input a detection instruction through a central control screen in the vehicle-mounted module 1 (it may be understood that a self-checking procedure of the vehicle-mounted LED display system is started). The vehicle-mounted module 1 sends a detection instruction to the deserializer 202; the deserializer decodes the detection instruction into LVDS and sends the LVDS to the control chip 201; the control chip 201 reads the data (such as temperature, pressure, voltage, etc.) detected by the sensor 205 according to the LVDS of the detection instruction, and then sends the data detected by the sensor 205 to the deserializer 202, and the data is returned to the vehicle module 1 by the deserializer 202. In this way, the vehicle-mounted LED display system can display the data acquired by the vehicle-mounted LED display system on the central control screen for the user to review.

In one example, as shown in fig. 9, the LED display panel 301 includes a decoding chip 3011, a driving chip 3012, and light beads 3013. The decoding chip 3011 and the driving chip 3012 are respectively connected to the control chip 201 (for example, FPGA) and receive the first display data sent by the control chip 201. The first display data may include RGB data and control driving signals (e.g., ABCDE row signals, latch signals, OE enable signals, gclk global clock signals, dclk pixel clock signals, etc.). The decoding chip 3011 receives the ABCDE row signal sent by the main control chip 201, and performs row scanning on the lamp panel according to the ABCDE row signal. The driving chip 3012 receives the latch signal, the OE enable signal, the Gclk global clock signal, the Dclk pixel clock signal and other control driving signals and RGB data sent by the main control chip 201, so as to realize the lighting control of each 3013 in the lamp panel, and enable the lamp panel to present the pattern of the display material under the control of the decoding chip 3011 and the driving chip 3012.

In one embodiment, the onboard LED display system may also automatically detect if there is a dead spot in the LED display panel (i.e., if the beads 3013 in the LED display panel 301 are shorted or open). For example, after the control chip 201 receives the detection instruction sent by the vehicle engine module 1, each LED display panel 301 may be controlled to feed back the lamp panel information, and the dead pixel information of the LED display panel 301 may be determined according to the lamp panel information.

For example, the light panel information may include the number of bits displayed by each light bead 3013 in the LED display panel 301. For example, in the first display data sent by the control chip 201 to the LED display panel 301, each bead 3013 needs to display RGB data of 8 bits, if the RGB data displayed by a certain bead 3013 in the panel information returned by the LED display panel 301 is 8 bits, the bead 3013 is normal, and if the RGB data displayed by the bead 3013 is less than or greater than 8 bits, the bead 3013 is a defective pixel in the LED display panel 301. The dead pixel information generated by the control chip 201 may include the number of dead pixels existing in each LED display panel 301, and may also include the positions of each dead pixel. When the number of dead pixels exceeds the set value, the display function of the LED display panel is obviously affected, and the dead pixel information can also comprise prompt information (for example, prompt a user to replace the LED display panel in time). Then, the control chip 201 sends the dead pixel information to the deserializer 202, and the dead pixel information is returned to the vehicle module 1 by the deserializer 202. The vehicle-mounted LED display system is used for displaying the dead pixel information detected by the vehicle-mounted LED display system on the central control screen for reference of a user.

Each group of LED display panels 301 provided by the embodiment of the present application includes a plurality of LED display panels 301, when the LED display panels 301 work, the LED display panels 301 at the edge position will have a problem of larger current loss due to the overlong connection between the LED display panels 301 near the edge position and the main control module 2, and thus the LED display panels 301 at the edge position have poor brightness and bright color display effect. In order to avoid the problem that the display effect of the LED display panels 301 near the edge is low, as shown in fig. 10, the vehicle-mounted LED display system provided in the present application may further set a corresponding digital chip 206 for each LED display panel 301, where the digital chip 206 may perform signal enhancement on the signal transmitted between the control chip 201 and the corresponding LED display panel 301, so as to enhance the current intensity transmitted between the main control module 2 and each LED display panel 301.

Alternatively, the digital chip 206 may be a 74HC245 chip.

In one example, the LED display panels 301 may further include a memory chip 3014 as shown in fig. 11, where each LED display panel 301 is provided with a memory chip 3014, and the memory chip 3014 is used to store correction data (including brightness and color of the beads 3013 in the LED display panel 301) of the LED display panel 301.

Alternatively, the memory chip 3014 may be a Flash chip. Because the Flash chip is in communication with other devices through a serial peripheral interface (Serial Peripheral Interface, SPI) bus, and each group of LED display panels 301 provided by the embodiment of the application is provided with a plurality of LED display panels 301, if the memory chip 3014 of each LED display panel 301 is directly connected with the main control module 2, the main control module 2 needs to have a plurality of pins, and the manufacturing process is complicated.

Therefore, in order to reduce the manufacturing process, the main control module 2 provided in the embodiment of the present application may further include a data selector 207 as shown in fig. 12, where the data selector 207 may be respectively connected to the memory chip 3014 of each LED display panel 301 through a Flash bus, so that the main control module 2 may read the correction data in the memory chip 3014 through the data selector 207 in a data selection manner. For example, if a portion of the LED display panels 301 in a certain group of LED display panels 301 is found to have abnormal brightness during use, the data selector 207 may read the correction data (i.e. the brightness of the light beads 3013) stored in the memory chips 3014 of the LED display panels 301 with abnormal brightness, and adjust the brightness of the LED display panels 301 according to the brightness, for example: the intensity of the current applied to the beads 3013 in the LED display panel 301 is increased or decreased.

In an example, as shown in fig. 13, the vehicle-mounted LED display system provided in the embodiment of the present application may further include a power module 4, where the power module 4 is respectively connected to the vehicle-mounted module 1, the vehicle-mounted battery 5, and the main control module 2, and the power module 4 is configured to control the vehicle-mounted battery 5 to supply power to the main control module 2 according to an enabling signal sent by the vehicle-mounted module 1, so as to start the main control module 2.

According to the vehicle-mounted LED display system provided by the embodiment of the application, the LED display panel 301 replaces a traditional car lamp to indicate the state of the car, and car condition information (such as the running state of the car, the front car condition, the internal state of the car and the like) can be displayed in an image mode based on car machine signals, so that the car lamp indication with more richness and flexibility is realized. Moreover, the lamps at different positions can be realized through the spliced plurality of LED display panels 301, so that the lamps at different positions can realize high-resolution image display. Therefore, the vehicle-mounted LED display system provided by the application can be used for indicating the vehicle lamp through the richer and higher-recognition-degree pictures.

It should be noted that, the vehicle-mounted LED display system provided in the present application may include two sets of LED display panels 301 (i.e., two lamps 3), so that a vehicle applying the vehicle-mounted LED display system may display more screen information. For example, when the vehicle-mounted LED display system is applied to a new energy vehicle, one of the lamps 3 may be used to display information such as vehicle conditions and road conditions, and the other lamp 3 may display charging information when the new energy vehicle is charged. For another example, when the vehicle-mounted LED display system is applied to other commercial vehicles such as buses, one of the lamps 3 can be used for displaying information such as platform, vehicle condition and road condition, and the other lamp 3 can be used for displaying advertisement information, so that the vehicle can display key information, for example, platform information, and the vehicle can realize the purpose of commercial propaganda.
