[0020] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The embodiments of the present application provide a multifunctional instrument display method based on synchronized backlighting. The execution entity of the multifunctional instrument display method based on synchronized backlighting includes, but is not limited to, at least one of electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiments of the present application. In other words, the multifunctional instrument display method based on synchronized backlighting can be executed by software or hardware installed on a terminal device or a server device, where the software can be a blockchain platform. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0022] Reference Figure 1 FIG2 is a flow chart of a multifunctional instrument display method based on backlight synchronous light guidance provided by an embodiment of the present invention. In this embodiment, the multifunctional instrument display method based on backlight synchronous light guidance includes: S1. Obtain backlight array information of a multi-function instrument panel.

[0023] It is understood that a multi-function instrument panel refers to a comprehensive display interface that integrates multiple traditional display functions such as speed, RPM, fuel level, and temperature, and incorporates extended functions such as navigation, multimedia, and vehicle status monitoring. Backlight array information refers to a data set including the physical location, electrical parameters, and optical characteristics of the backlight array. The backlight array can be, for example, a backlight LED. For example, when the backlight array is an 8×16 three-primary-color μLED matrix, the backlight array information can include data such as the coordinates, rated current, wavelength, and brightness curve of each LED in the μLED matrix.

[0024] It can be understood that the embodiment of the present application can obtain data such as electrical parameters and optical characteristics by powering on the backlight array and recording the backlight array operation data, and then positioning the backlight array to obtain the physical position of the backlight array. Finally, the physical position, electrical parameters, optical characteristics and other data of the backlight array are aggregated to obtain backlight array information.

[0025] S2. Receive the instrument panel light guide request sent by the signal sending port, and parse the instrument panel light guide request to obtain the light source configuration of the area to be light guided and the initial area.

[0026] It is understandable that the signal sending port refers to a communication interface that can send instructions or requests to the instrument panel signal receiving port, such as a mobile phone app or a vehicle-mounted light sensing system. It should be noted that the connection between the signal sending port and the instrument panel signal receiving port can be wired or wireless. For example, the mobile phone app can send the "start welcome light" instruction to the instrument panel signal receiving port of the instrument wirelessly. The instrument panel light guide request refers to a complete data packet carrying the "functional data to be illuminated" information. For example, in a vehicle instrument panel, the instrument panel light guide request can be a complete data packet carrying the "vehicle speed data to be illuminated". The area to be illuminated refers to the specific geometric area on the multi-function instrument panel that needs to be illuminated by the backlight, such as the speed digital display area in the vehicle multi-function instrument panel. The initial area light source configuration is the default backlight parameter set for the area to be illuminated by the multi-function instrument panel. For example, the initial area light source configuration of the speed data area in the multi-function instrument panel can be 30% white light and no animation.

[0027] It can be understood that in the embodiment of the present application, the instrument panel signal receiving port can monitor external trigger events. When an external trigger event occurs outside the multi-function instrument panel, the external trigger event can generate an original trigger signal and activate the signal sending port. Furthermore, the signal sending port can send an instrument panel light guide request to the instrument panel signal receiving port based on the original trigger signal.

[0028] It can be understood that after the instrument panel signal receiving port receives the instrument panel light guiding request sent by the signal sending port, by parsing the instrument panel light guiding request, it is possible to clearly determine the area where light guiding is required and the initial light source configuration information of the area, that is, the area to be guided and the initial area light source configuration.

[0029] Specifically, parsing the instrument panel light guide request to obtain the light source configuration of the area to be light guided and the initial area includes: Extracting information from the instrument panel light guide request to obtain instrument panel display information; Positioning the instrument panel display area based on the instrument panel display information to obtain an area to be guided light; Based on the preset regional light source configuration parameters and the area to be light-guided, light source parameter matching is performed to obtain an initial regional light source configuration.

[0030] It is understood that the instrument panel display information refers to the data required to be displayed on the multi-function instrument panel contained in the instrument panel light guide request, such as vehicle speed, time, remaining fuel level, etc. The preset regional light configuration parameters refer to the pre-set initial light configuration parameters for each zone, where the initial light configuration parameters include data such as brightness, color, and color temperature.

[0031] It can be understood that in the embodiment of the present application, the instrument panel signal receiving port splits the instrument panel light-guiding request into multiple fields such as a request header and a request body, and then locates the information of the field containing the main information, so as to obtain the field position where information extraction is required. Furthermore, by reading the information at the field position, the instrument panel display information can be obtained. Secondly, by semantically understanding the instrument panel display information, the functional data that needs to be displayed by the multi-function instrument panel is determined, and the dial area of ​​the multi-function instrument panel where the functional data is displayed is queried, that is, the area to be guided. Finally, according to the area to be guided, the pre-set regional light source configuration parameters are traversed to determine the default light source parameters of the area to be guided, that is, the initial regional light source configuration.

[0032] It can be understood that the embodiment of the present application can clarify the information that needs to be displayed on the multi-function instrument panel by extracting information from the instrument panel light-guiding request. Secondly, by mapping the instrument panel display information to physical coordinates, the area to be guided light can be accurately circled, thereby enhancing the accuracy of light spot positioning. Finally, based on the preset regional light source configuration parameters, the brightness, color temperature, animation rhythm and other attributes of the area to be guided light are quickly matched, ensuring that the initial regional light source configuration of the area to be guided light corresponds to the hardware capabilities one by one, avoiding excessive or insufficient driving, and improving the light guidance accuracy of the multi-function instrument display.

[0033] S3. Based on the instrument panel light guide request, perform ambient light sensing on the multifunctional instrument panel to obtain ambient light intensity.

[0034] It can be understood that the ambient light intensity refers to the light intensity information of the environment surrounding the multi-function instrument panel.

[0035] It is understandable that the embodiment of the present application can capture the light intensity of the environment surrounding the multi-function instrument panel through a light intensity sensor, thereby obtaining the ambient light intensity.

[0036] Specifically, the step of sensing the ambient light source of the multifunctional instrument panel based on the instrument panel light guide request to obtain the ambient light intensity includes: Based on the instrument panel light guide request, capturing an ambient light signal of the multifunctional instrument panel to obtain an original light signal; Performing photoelectric conversion on the original optical signal to obtain an analog voltage value; Based on the analog voltage value, light intensity mapping is performed to obtain the ambient light source intensity.

[0037] It is understood that the original optical signal refers to the instantaneous value of the photocurrent or photovoltage of natural or artificial light propagating in the space around the multi-function instrument panel. The analog voltage value refers to the continuous time and continuous amplitude voltage waveform representation of the original optical signal.

[0038] It can be understood that the embodiment of the present application can use the optical window and microlens array in the light intensity sensor to converge the natural light or artificial light propagating in the space around the multi-function instrument panel to the effective photosensitive surface of the sensor chip in the light intensity sensor, thereby obtaining the original light signal. Secondly, the semiconductor photoelectric effect can be used to convert the light energy in the captured original light signal into a measurable electrical signal, that is, an analog voltage value. Finally, by performing analog-to-digital conversion on the analog voltage value, a digital sampling value is obtained, and then the digital sampling value is filtered and denoised to obtain a denoised sampling value. Furthermore, the denoised sampling value is linearly calibrated to obtain a calibrated brightness value, and then the calibrated brightness value is linearly or nonlinearly mapped to obtain the light intensity around the multi-function instrument panel, that is, the intensity of the ambient light source.

[0039] It can be understood that the embodiment of the present application captures the ambient light signal of the multi-function instrument panel based on the instrument panel light guide request to obtain the original light signal, which can ensure the real-time performance of light detection. Secondly, the original light signal is converted into an analog voltage value, which can improve the readability and stability of the original light signal. Finally, the analog voltage value is mapped to the light intensity space to realize the conversion of the analog voltage value to the ambient light intensity, which can improve the quantitative perception of the multi-function instrument panel to external light.

[0040] S4. Based on the instrument panel light guiding request, perform carrier state perception on the multifunctional instrument panel to obtain carrier state information.

[0041] It is understandable that the carrier status information refers to information such as the carrier speed and carrier acceleration of the multi-function instrument panel.

[0042] It is understandable that, while obtaining the intensity of the ambient light source, the embodiment of the present application can also record data such as the speed and acceleration of the carrier of the multi-function instrument panel according to the instrument panel light guide request, thereby obtaining the carrier status information.

[0043] S5. Determine the carrier operation mode based on the ambient light intensity and the carrier status information.

[0044] It can be understood that the carrier operation mode is determined by the operation environment of the carrier of the multi-function instrument panel. For example, when the operation environment of the carrier of the multi-function instrument panel is a tunnel, the carrier operation mode may be a tunnel driving mode.

[0045] In detail, determining the carrier operation mode based on the ambient light intensity and the carrier state information includes: quantifying the intensity of the ambient light source to obtain a light intensity level; Based on the carrier state information, perform state tag matching to obtain a target state tag; Based on the light intensity level and the target state label, a rule base search is performed to obtain the carrier operation mode.

[0046] It is understood that the light intensity level refers to the discrete levels obtained by quantizing the ambient light intensity level, for example, extremely dim, dim, medium, bright, and extremely bright. The target state label refers to the discrete set of levels obtained by quantizing the levels of each state information in the carrier state information. For example, speed information can be quantized into multiple levels such as extremely fast, fast, medium, slow, and extremely slow, and acceleration information can be quantized into multiple levels such as extremely large, large, medium, small, and extremely small. If the carrier state information indicates that the speed information is slow and the acceleration information is extremely small, the target state label can be "slow and uniform speed."

[0047] It can be understood that in the embodiment of the present application, the ambient light intensity can be quantified into the corresponding light intensity level according to the pre-set mapping rules between the light source intensity and the light intensity level. For example, when the ambient light intensity is 0-50lx, the light intensity level is set to "very dark"; when the ambient light intensity is 50-500lx, the light intensity level is set to "dark"; when the ambient light intensity is 500-5000lx, the light intensity level is set to "medium"; when the ambient light intensity is 5000-25000lx, the light intensity level is set to "bright"; when the ambient light intensity is greater than 25000lx, the light intensity level is set to "very bright".

[0048] Secondly, in the embodiment of the present application, the carrier state information can also be quantified into corresponding state levels according to a pre-set mapping rule between carrier state information and state levels, and then multiple state levels can be aggregated to obtain a target state label.

[0049] Finally, the operating mode corresponding to the above-mentioned light intensity level and target state label is retrieved from the pre-built rule library to obtain the carrier operating mode. For example, when the light intensity level is dark and the target state labels include "straight driving", "low speed" and "constant speed", the rule library retrieval shows that the carrier is in a tunnel. Therefore, the carrier operating mode can be the tunnel operating mode.

[0050] It can be understood that the embodiment of the present application quantifies the continuous ambient light intensity into discrete levels, so that the multi-function instrument panel can quickly understand the external light intensity. Secondly, the carrier status information is used to complete the status label matching, and the carrier status information is mapped to the target status label, which can ensure that the light guide configuration of the multi-function instrument panel corresponds to the driving scene of the carrier in real time. Finally, the pre-built rule library is jointly queried based on the light intensity level and the target status label to obtain the carrier operation mode, which facilitates the multi-function instrument panel to implement light guide decisions, thereby improving the light guide efficiency and accuracy of the multi-function instrument panel.

[0051] S6. Based on the carrier operation mode, adjust the initial area light source configuration to obtain the target area light source configuration.

[0052] It can be understood that the target area light source configuration refers to the actual light source configuration information of the area to be guided after environmental correction.

[0053] It can be understood that, the configuration adjustment of the initial regional light source configuration based on the carrier operation mode to obtain the target regional light source configuration includes: Based on the carrier operation mode, a light configuration prediction is performed on the area to be light-guided to obtain a regional light configuration; Extracting light configuration information from the initial regional light source configuration to obtain an initial regional light configuration; Based on the regional light configuration and the initial regional light configuration, brightness parameters of the initial regional light source configuration are adjusted to obtain a target regional light source configuration.

[0054] It's understood that a regional lighting configuration refers to a combination of lighting parameters, such as brightness, color temperature, and color saturation, for the area on the multi-function instrument panel to be illuminated. An initial regional lighting configuration refers to the default brightness, color temperature, and other lighting parameters for the area to be illuminated, without considering the surrounding environment of the multi-function instrument panel.

[0055] It can be understood that in the embodiment of the present application, the historical brightness parameters corresponding to the carrier operation mode of the multi-function instrument panel, that is, the regional brightness configuration, can be determined based on historical experience, and then the parameters of the initial regional brightness configuration in the initial regional light source configuration can be adjusted according to the regional brightness configuration to obtain a complete target regional light source configuration. For example, when the current carrier operation mode of the multi-function instrument panel is the tunnel operation mode, according to the historical data recorded by the multi-function instrument panel, it can be known that the multi-function instrument panel requires a stronger light source brightness, that is, the regional brightness configuration is a high-brightness parameter configuration.

[0056] It can be understood that according to the carrier operation mode, the historical light configuration query of the light-guiding area is carried out, which can quickly lock the ideal brightness and color temperature of the light-guiding area in the carrier operation mode scenario. Secondly, the default parameters related to the brightness are extracted from the initial regional light source configuration to form the initial regional light configuration, which is convenient for comparison with the regional light configuration. Finally, based on the regional light configuration and the initial regional light configuration, the brightness parameters of the initial regional light source configuration are adjusted, so that the obtained target regional light source configuration meets both user needs and the current environment of the carrier, so that the multi-functional instrument panel does not waste energy and maintains readability.

[0057] The step of predicting the light configuration of the area to be light-guided based on the carrier operation mode to obtain the regional light configuration includes: Get historical light guide data; Performing information matching on the carrier operation mode, the area to be light-guided, and historical light-guided data to obtain historical light source configuration matching items; Perform light extraction on the historical light source configuration matching items to obtain regional light configuration.

[0058] It is understood that historical light guidance data refers to the light parameter information of various areas in various environments stored within a year or month before the current time node. Historical light source configuration matching items refer to the light parameter information of the area to be guided in the environment represented by the carrier operation mode.

[0059] It is understood that prior to the present embodiment, the multi-function instrument panel would record its own light guide data to form light guide storage data. It should be noted that the light guide data recorded by the multi-function instrument panel includes the area information of the multi-function instrument panel, the carrier operating mode, and the light source configuration parameters of each area. Therefore, the present embodiment can obtain historical light guide data by querying the database storing the light guide storage data. Secondly, the carrier operating mode of the multi-function instrument panel at the current time node and the area to be lighted are matched with the corresponding information in the historical light guide data. When the carrier operating mode of the multi-function instrument panel at the current time node and the area to be lighted are successfully matched with the historical light guide data, the light source configuration parameters in the successfully matched historical light guide data are used as the historical light source configuration matching items. If the carrier operating mode of the multi-function instrument panel at the current time node and the area to be lighted cannot find the same data items in the historical light guide data, there is no need to adjust the initial regional light source configuration. Finally, when the carrier operating mode of the multi-function instrument panel at the current time node and the area to be lighted are successfully matched with the historical light guide data, the data related to the brightness parameters in the historical light source configuration matching items are read to obtain the regional brightness configuration.

[0060] The embodiments of the present application obtain historical light guide data and, after obtaining the historical light guide data, perform pattern matching on the carrier operation mode with the historical carrier operation mode in the historical light guide data, and perform data matching on the area to be light guided with the historical light guide area in the historical light guide data. This allows for accurate matching of the light source configuration most suitable for the area to be light guided in the carrier operation mode, i.e., the historical light source configuration matching item. This reduces the need for light source adjustment for the area to be light guided and improves the display accuracy of the multi-function instrument. Furthermore, brightness extraction is performed on the historical light source configuration matching item to obtain the regional brightness configuration, facilitating the rapid and accurate application of brightness parameters that have been optimized under similar conditions in the area to be light guided, thereby enhancing the display efficiency of the multi-function instrument panel.

[0061] S7. Based on the backlight array information and the target area light source configuration, adjust the light source of the area to be light-guided to obtain a target light-guiding area.

[0062] It can be understood that the target light-guiding area refers to the uniform and required light spot area actually presented on the multi-function instrument panel after the light source is adjusted.

[0063] In detail, the light source adjustment of the to-be-light-guided area based on the backlight array information and the target area light source configuration to obtain the target light-guided area includes: Performing regional analysis on the area to be light-guided to obtain a regional function; Based on the regional function, data is captured to obtain original functional data; Based on the backlight array information, the target area light source configuration and the original functional data, light guiding processing is performed on the area to be light guided to obtain a target light guiding area.

[0064] It is understood that the regional function refers to the function represented by the data displayed in the light-guiding area. The original function data refers to the carrier data corresponding to the regional function, such as speed, acceleration, remaining fuel, etc.

[0065] It can be understood that in the embodiment of the present application, a comparison table describing the function corresponding to each area is pre-stored. Therefore, by querying the comparison table, the regional analysis of the area to be light-guided can be achieved, the function corresponding to the area to be light-guided can be clarified, and the regional function can be determined. Secondly, after clarifying the regional function, data acquisition can be achieved by recording the data required for the regional function. For example, when the regional function is a speed display function, it is necessary to record the carrier speed data of the multi-function instrument panel to obtain the original functional data. Finally, after clarifying the original functional data to be displayed, the light source data of the area to be light-guided can be adjusted using the backlight array according to the backlight array information and the target area light source configuration to achieve light guiding processing of the area to be light-guided, and then the target light guiding area can be obtained.

[0066] It can be understood that the embodiment of the present application performs regional analysis on the light-guiding area, abstracts the light-guiding area into regional functions, and then captures data based on the regional functions to obtain original functional data, thereby ensuring that the regional light-guiding can clearly identify the data that needs to be displayed. Furthermore, based on the backlight array information, the target area light source configuration and the original functional data, the light-guiding area is processed to obtain the target light-guiding area, which can make the light spot in the target light-guiding area both uniform and low-consumption, thereby improving the light-guiding efficiency of the multi-function instrument panel.

[0067] The step of performing light guiding processing on the area to be light guided based on the backlight array information, the light source configuration of the target area, and the original functional data to obtain the target light guiding area includes: Generate a regional light guide instruction based on the target area light source configuration, the area to be light guided and the original functional data; Reading the array status of the backlight array information to obtain a current light source capability table; Based on the regional light guiding instruction and the current light source capability table, regional light dimming is performed on the area to be light guided to obtain a target light guiding area.

[0068] It is understood that the local light guide instruction is used to control the light guide effect of the area to be guided. The current light source capability table is a table that displays the capabilities of the backlight array. The table records the performance of each light source in the backlight array under current environmental conditions, such as maximum brightness, color temperature range, etc.

[0069] It can be understood that the embodiments of the present application can generate regional light guiding instructions for controlling the light guiding effect of the area to be guided by light by integrating the target area light source configuration, the area to be guided by light and the original functional data into a data packet. Secondly, by reading the current status of each light source in the backlight array information, the array status of the backlight array information can be read, wherein the current status can be the performance of each light source in the backlight array under the current environmental conditions, and the performance of each light source in the backlight array under the current environmental conditions can be clarified, that is, the current light source capability table. Finally, according to the regional light guiding instructions and the performance of each light source under the current environmental conditions displayed in the current light source capability table, the performance status of each light source in the backlight array is adjusted, and regional dimming of the light guiding area can be achieved. It should be noted that when the area to be guided by light can meet the requirements of the regional light guiding instructions, the target light guiding area can be obtained.

[0070] It can be understood that the embodiment of the present application generates accurate regional light guiding instructions based on the target area light source configuration, the area to be guided and the original functional data, and can solidify information such as brightness, color temperature and animation rhythm into an executable instruction stream, thereby ensuring that user needs correspond to the display content one by one. Secondly, by reading the array status in the backlight array information, the current light source capability table is obtained, which is convenient for real-time grasp of the performance information of each light source in the backlight array, so that the dimming range of each light source in the backlight array can be clearly defined when guiding light in the area to be guided. Finally, based on the regional light guiding instructions, the dimming capability of each light source in the backlight array is constrained by the current light source capability table, and regional dimming is performed on the area to be guided, so that the light spot uniformity and power consumption of the target light guiding area can be optimized at the same time, thereby improving the light guiding efficiency of the multi-function instrument panel.

[0071] It should be noted that in order to ensure the display effect of the target light-guiding area, after obtaining the target light-guiding area, the embodiment of the present application can also adjust the brightness of the target light-guiding area according to the uniformity of the light spot of the target light-guiding area, thereby making the display effect of the multi-functional instrument panel more prominent.

[0072] Specifically, after adjusting the light source of the to-be-light-guided area based on the backlight array information and the target area light source configuration to obtain the target light-guided area, the method further includes: Performing optical path verification on the target light guiding area to obtain light spot uniformity; Based on the light spot uniformity, error compensation is performed to obtain a corrected brightness instruction; Based on the brightness correction instruction, the brightness of the target light guide area is corrected to obtain a corrected light guide area.

[0073] It is understood that light spot uniformity refers to the uniformity of the brightness distribution of the light spot within the target light guide area. The brightness correction instruction refers to the instruction used to adjust the brightness of the light source in the target light guide area. The corrected light guide area refers to the target light guide area where the light spot uniformity is improved after brightness correction.

[0074] It can be understood that the embodiments of the present application can evaluate the uniformity of the light spot in the target light guiding area by calculating the light intensity difference between adjacent sensors, wherein adjacent sensors refer to two adjacent sensors in the target light guiding area among multiple sensors for detecting light intensity distribution. Furthermore, if the light intensity difference is less than a preset threshold, it is considered that the light spot uniformity is good and no brightness compensation is required. If the light intensity difference is equal to or greater than the preset threshold, it is considered that the light spot uniformity is poor and brightness compensation is required for the area where the adjacent sensors are located, and a corrected brightness instruction can be generated accordingly. Finally, according to the corrected brightness instruction, brightness compensation can be achieved by adjusting the driving current of the area where the adjacent sensors are located or changing the pulse width modulation duty cycle, thereby achieving the effect of brightness correction and converting the target light guiding area into a corrected light guiding area.

[0075] It can be understood that the embodiments of the present application can verify the optical path of the target light guiding area by calculating the light intensity difference between adjacent sensors, and capture the light spot uniformity of the target light guiding area in real time, so that the multi-function instrument panel can locate the place where there is brightness difference in the target light guiding area in real time. Furthermore, according to the potential brightness difference in the target light guiding area, a correction brightness instruction can be generated, and according to the correction brightness instruction, the brightness of the target light guiding area can be corrected to obtain a corrected light guiding area, which can reduce the brightness difference in the corrected light guiding area, thereby making the light guiding effect of the multi-function instrument panel more prominent.

[0076] By acquiring the backlight array information of the multi-function instrument panel, the present invention can fully understand the layout and characteristics of the backlight array in the multi-function instrument panel. Furthermore, the instrument panel signal receiving port receives the instrument panel light guide request sent by the signal sending port and parses the instrument panel light guide request, so as to accurately obtain the area to be guided and the initial light source configuration, providing a basis for the display adjustment of the multi-function instrument panel. Secondly, based on the instrument panel light guide request, the multi-function instrument panel performs ambient light perception and can obtain the ambient light intensity. The multi-function instrument panel performs carrier state perception and can obtain carrier state information. Then, based on the ambient light intensity and the carrier state information, the carrier operation mode can be determined, so that the multi-function instrument panel can dynamically adjust the light source configuration according to the carrier operation mode, thereby obtaining a target area light source configuration that is more suitable for the carrier operation mode. Finally, based on the backlight array information and the target area light source configuration, the light source adjustment is performed on the area to be guided, which can achieve a uniform and efficient target light guiding effect, improve the light guiding accuracy of the multi-function instrument panel, and thus improve the user experience.
