Description

Technical Field

[0001] This invention relates to the field of display module operation status management technology, and in particular to an adaptive decision-making method and system applied to display modules. Background Technology

[0002] Display modules are widely used in industrial displays, commercial displays, automotive displays, video wall displays, and other display scenarios requiring continuous operation. In practical applications, display modules typically operate for extended periods, and their backlight drive status, display brightness, and temperature continuously change with runtime, load, and environmental conditions. To ensure that display modules maintain their intended operating state, the acquisition, monitoring, and management of relevant operating parameters have become crucial aspects of display module operation management. Current technologies typically combine operating parameters such as current, brightness, and temperature to determine the current operating status of the display module and adjust parameters, control operation, or provide status indicators accordingly.

[0003] For display modules operating for extended periods, their operating parameters over a specific timeframe reflect continuous changes in their operational status. In engineering applications, display modules may experience variations in brightness, drive status, abnormal temperature rise, or display instability after prolonged operation. Current technologies typically address these issues by relying on single-detection results, individual parameter changes, or immediate operational status. They struggle to effectively assess changes in the current operational status by considering the changes in the display module's operating parameters over a period and its current operating mode, and consequently, to differentiate parameter adjustment requirements under different operating modes. This deficiency leads to insufficiently targeted assessment of status changes in display module operation management, making it difficult to distinguish processing needs across different operating modes. Consequently, subsequent parameter adjustments, operational control, and status outputs lack specificity, limiting the effectiveness of display module operation management in long-term operating scenarios. Summary of the Invention

[0004] To address the aforementioned issues, an adaptive decision-making method and system for display modules are proposed. This method solves the technical problem that existing technologies struggle to effectively judge changes in the current operating state by combining the changes in the display module's operating parameters over a period of time with the current operating mode, and thereby distinguish the parameter correction requirements under different operating modes.

[0005] To achieve the above objectives, a first aspect of the present invention provides an adaptive decision-making method for a display module, characterized by comprising the following steps: The operating mode of the display module in its current working state is obtained, as well as the operating parameters continuously acquired within a preset observation period, wherein the operating parameters include at least the backlight driving current parameter, the display brightness parameter, and the temperature parameter; Based on the operating parameters, a deviation result of the operating state representing the current operating state of the display module relative to the preset operating requirements corresponding to the working mode is generated; Based on the deviation results of the operating state and the working mode, a parameter correction requirement determination result is formed, which characterizes the parameter correction requirement status of the display module in the current working mode. Based on the parameter correction requirement determination result, select the parameter correction strategy corresponding to the parameter correction requirement status; According to the parameter correction strategy, parameter correction processing is performed on the operating parameters of the display module; Output the correction result corresponding to the parameter correction process.

[0006] Optionally, the step of generating an operating state deviation result, representing the current operating state of the display module relative to the preset operating requirements corresponding to the working mode, based on the operating parameters, includes: Based on the described working mode, determine the preset operating requirements corresponding to the described working mode; The operating parameters are compared with the preset operating requirements.

[0009] Optionally, the step of forming a parameter correction requirement determination result characterizing the parameter correction requirement status of the display module in the current working mode based on the deviation result of the operating state and the working mode includes: Invoke the parameter correction judgment condition corresponding to the working mode; The deviation of the operating state is compared with the parameter correction judgment condition for identification; Determine the parameter correction requirement status of the display module in the current working mode; The parameter correction requirement status is adjusted based on the parameters to form the parameter correction requirement determination result.

[0010] Optionally, the parameter correction requirement state includes at least a hold state of maintaining the current operating parameters and a correction state of adjusting at least one operating parameter; the parameter correction requirement determination result that characterizes the parameter correction requirement state of the display module in the current operating mode includes: For the same deviation from the operating state, different parameter correction judgment conditions are applied under different working modes; Different parameter correction requirements are determined based on different parameter correction judgment conditions; By using different parameters to adjust the demand state, a subsequent parameter adjustment strategy can be determined.

[0011] Optionally, selecting a parameter correction strategy corresponding to the parameter correction requirement state based on the parameter correction requirement determination result includes: Based on the parameters, the required state is corrected, and the working parameters to be corrected are determined. Based on the preset operating requirements corresponding to the operating mode, determine the corresponding correction method for the operating parameters to be corrected; The parameter correction strategy is formed based on the working parameters to be corrected and the corresponding correction methods.

[0012] Optionally, performing parameter correction processing on the operating parameters of the display module according to the parameter correction strategy includes: According to the parameter correction strategy, adjust the operating parameters corresponding to at least one of the backlight drive current parameters and display brightness parameters so that the adjusted operating parameters meet or tend to meet the preset operating requirements corresponding to the operating mode.

This improves the pertinence of judging changes in the current operating state of the display module, enhances the ability to distinguish parameter correction requirements under different working modes, and improves the correspondence between parameter correction processing and the current operating state.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Example 1 This embodiment describes the operation management process of a display module under long-term operation scenarios. The controller first judges the changes in the current operating state of the display module based on continuously acquired operating parameters within a preset observation period. Then, it determines whether the operating parameters need adjustment based on the current working mode. Based on this, it determines the corresponding parameter correction strategy, executes the corresponding parameter correction processing, and outputs the correction processing result. Compared to methods that directly process based on a single detection result, a single parameter change, or an immediate state, this embodiment combines continuously acquired operating parameters over a period of time with the current working mode, thereby forming a processing procedure corresponding to the current operating state. This is suitable for judging and correspondingly processing the operating state of the display module under continuous operating conditions.

[0020] like Figure 1As shown, this embodiment uses a continuously operating display module as an example to illustrate the adaptive decision-making method for the display module. The display module is equipped with a controller. The controller is connected to a backlight driving unit, a brightness detection unit, and a temperature detection unit. The controller is used to acquire the operating mode of the display module in its current operating state and continuously acquires the operating parameters of the display module within a preset observation period. Based on the acquired results, subsequent judgments and processing are then performed. In this embodiment, the display module is in a long-term operating scenario. The controller does not process based solely on a single sample value, but continuously acquires operating parameters within a preset observation period, and then combines this with the current operating mode to form a judgment result on the deviation of the operating state and the parameter correction requirement. Based on this, a parameter correction strategy is determined and parameter correction processing is executed.

[0021] S101. Obtain working mode and operating parameters. The controller acquires the operating mode of the display module in the current working state and continuously acquires the operating parameters of the display module according to the preset sampling period within the preset observation period.

[0022] In this embodiment, the controller pre-sets an observation period and a sampling cycle. During the observation period, the controller continuously acquires operating parameters according to the sampling cycle. These operating parameters include at least backlight drive current parameters, display brightness parameters, and temperature parameters. The controller organizes the operating parameters acquired during the observation period in chronological order to form a set of operating parameters for the current judgment. This set of operating parameters serves as the basis for the historical operating parameters upon which the current judgment is based.

[0023] The controller also acquires the current operating mode. The operating mode can be determined by the current running configuration of the display module, the current display task, or the current mode identifier. In this embodiment, the controller reads the current mode identifier and determines that the display module is in the current operating mode. The controller invokes this current operating mode when a preset operating requirement is subsequently generated, and invokes it again when a parameter correction requirement determination result is subsequently generated.

[0024] In this step, the controller acquires continuously changing operating parameters within a preset observation period, rather than single-point data at a specific moment. These operating parameters within the observation period form the basis of the historical operating parameters upon which the current judgment is based, reflecting the changes in the display module's operating state during that period. Therefore, the subsequent deviation in operating state generated by the controller is not based on instantaneous changes at a single sampling point, but rather on continuous state changes occurring throughout the observation period.

[0025] S102, Generate operational status deviation results The controller generates deviation results of the operating status based on the operating parameters.

[0026] First, the controller determines the preset operating requirements corresponding to the current operating mode. These preset operating requirements are parameter requirements pre-set for different operating modes. The preset operating requirements include at least two of the following parameters: backlight drive current parameter, display brightness parameter, and temperature parameter. The controller then uses the combination of parameter requirements corresponding to the current operating mode as the preset operating requirements for that mode.

[0027] Subsequently, the controller compares the operating parameters during the observation period with the preset operating requirements corresponding to the current working mode. The controller determines whether the backlight drive current parameter, display brightness parameter, and temperature parameter continuously deviate from the corresponding parameter requirements. In this embodiment, when an operating parameter deviates from the corresponding parameter requirement at multiple consecutive sampling points during the observation period, the controller determines the deviation state corresponding to that operating parameter. Based on this, the controller determines at least several of the current deviation state, brightness deviation state, and temperature deviation state.

[0028] After obtaining the aforementioned deviation states, the controller extracts at least two deviation states. The controller then forms a combined result based on these two extracted deviation states. Finally, the controller generates an operational state deviation result based on this combined result. Therefore, the controller does not directly generate an operational state deviation result based on the instantaneous change of a single sampling point, but rather on the deviation states that continuously exist within the observation period. Different combinations of deviation states can generate different operational state deviation results, thereby reflecting the state changes of the display module within the current observation period and providing a basis for subsequently distinguishing different parameter correction requirements.

[0029] S103, Result of Formation Parameter Correction Requirement Determination The controller determines the parameter correction requirements based on the deviation from the operating status and the current working mode.

[0030] The controller first invokes the parameter correction judgment condition corresponding to the current operating mode. The parameter correction judgment condition is a judgment condition pre-set for different operating modes, used to determine whether the deviation of the current operating state allows the current operating parameters to be maintained, or whether at least one operating parameter needs to be adjusted.

[0031] Subsequently, the controller compares the deviation from the current operating state with the parameter correction criteria corresponding to the current working mode. If the comparison indicates that the deviation still allows maintaining the current operating parameters, the controller determines the current parameter correction requirement to be in a "maintain" state. If the comparison indicates that maintaining the current operating parameters is no longer advisable, the controller determines the current parameter correction requirement to be in a "correction" state. The controller then generates a parameter correction requirement determination result based on the determined parameter correction requirement state.

[0032] In this embodiment, the same deviation from the operating state can correspond to different parameter correction requirements under different operating modes. That is, the controller does not directly enter parameter correction processing based solely on the deviation result, but first combines the parameter correction judgment conditions corresponding to the current operating mode to determine whether the operating parameters need adjustment, and then forms a parameter correction requirement judgment result. Therefore, the controller can not only determine the state changes exhibited by the display module during the current observation period, but also distinguish the corresponding processing requirements under different operating modes.

[0033] S104, Select parameter correction strategy The controller selects the parameter correction strategy corresponding to the current parameter correction requirement state based on the parameter correction requirement determination result.

[0034] When the parameter correction requirement determination result indicates that the current parameter correction requirement status is to be maintained, the controller selects a parameter correction strategy that maintains the current operating parameters.

[0035] When the parameter correction requirement determination result indicates that the current parameter correction requirement status is in the correction state, the controller first determines the working parameter to be corrected. Then, based on the preset operating requirements corresponding to the current operating mode, the controller determines the corresponding correction method for the working parameter to be corrected. The controller then forms a current parameter correction strategy based on the working parameter to be corrected and the corresponding correction method, and uses this parameter correction strategy as the parameter correction strategy selected for this processing.

[0036] For example, when the controller determines that the operating parameter to be corrected is the backlight drive current parameter, the controller will adjust the backlight drive current parameter to determine the corresponding correction method; when the controller determines that the operating parameter to be corrected is the display brightness parameter, the controller will adjust the display brightness parameter to determine the corresponding correction method; when the controller determines that the operating parameter to be corrected includes both the backlight drive current parameter and the display brightness parameter, the controller will determine the corresponding correction method respectively and form the current parameter correction strategy.

[0037] S105, Execution parameter correction processing The controller performs parameter correction processing on the operating parameters of the display module according to the parameter correction strategy.

[0038] If the selected parameter correction strategy is to maintain the current operating parameters, the controller will keep the current operating parameters unchanged.

[0039] If the selected parameter correction strategy involves adjusting at least one operating parameter, the controller adjusts at least one operating parameter of the display module according to the selected strategy, so that the adjusted operating parameter meets or tends to meet the preset operating requirements corresponding to the current operating mode. The operating parameters include at least the backlight drive current parameter and the display brightness parameter, and the temperature parameter is used to participate in the formation of operating state deviation results and the determination of parameter correction requirements. After performing the adjustment, the controller ensures that the adjusted operating parameter meets or tends to meet the preset operating requirements corresponding to the current operating mode.

[0040] For example, when the current parameter correction strategy requires adjustments to the backlight drive current and display brightness parameters, the controller adjusts the corresponding operating parameters and maintains the current operating mode afterward, ensuring the display module remains within the operating requirements corresponding to the current operating mode. In this step, the controller performs parameter correction processing corresponding to the current operating state, rather than uniformly processing all operating parameters.

[0041] S106. Output the correction processing result The controller outputs the correction results corresponding to the parameter correction processing.

[0042] In this embodiment, the controller outputs the operating parameters after parameter correction processing. Based on these corrected operating parameters, the controller also determines the operating status of the display module relative to the preset operating requirements of the current operating mode. The controller then outputs result information reflecting this operating status.

[0043] For example, after performing parameter correction processing, the controller outputs the adjusted backlight drive current parameters and display brightness parameters, and also outputs the current operating status result information of the display module. This operating status result information indicates whether the operating status of the display module after processing corresponds to the preset operating requirements of the current working mode. Therefore, the controller outputs not simply parameter changes, but the correction processing result corresponding to the current operating status. This correction processing result reflects both the changes in operating parameters after parameter correction processing and the changes in the operating status of the display module relative to the preset operating requirements of the current working mode.

[0044] In this embodiment, the controller first continuously acquires operating parameters within a preset observation period and uses these parameters as the basis for the current judgment based on historical operating parameters. The controller then determines preset operating requirements based on the current operating mode and forms an operating state deviation result based on the persistent deviation state within the observation period. The controller then combines the parameter correction judgment conditions corresponding to the current operating mode to form a parameter correction requirement judgment result, selects the corresponding parameter correction strategy, executes parameter correction processing, and outputs the correction processing result corresponding to the current operating state. Therefore, this embodiment does not directly process based on a single sample value, a single parameter, or an instantaneous state, but rather performs layered judgment and corresponding processing based on continuously acquired operating parameters over a period of time, combined with the current operating mode. Those skilled in the art can complete the entire process of acquiring operating parameters, forming operating state deviation results, forming parameter correction requirement judgment results, selecting parameter correction strategies, performing parameter correction processing, and outputting correction processing results based on this embodiment.

[0045] Example 2 Building upon the basic process of adaptive decision-making in the display module already explained in Example 1, this example further elaborates on the formation process of the operational state deviation result, the formation process of the parameter correction requirement determination result, and the formation process of the parameter correction strategy. This example focuses on... Figures 2 to 4 An explanation is provided. Among them, Figure 2 This is used to explain the formation process of the preset operating requirements corresponding to the current working mode and the determination process of the deviation state. Figure 3 Used to explain the process by which the operating state deviates from the result. Figure 4 This embodiment is used to illustrate the determination results of parameter correction requirements, parameter correction strategies, and the formation process of parameter correction processing. This embodiment will not repeat the basic process of Embodiment 1, but will only explain the parts required for further elaboration.

[0046] like Figure 2 As shown, in this embodiment, the controller first determines the current operating mode. The current operating mode can be determined by the current running configuration of the display module, the current display task, or the current mode identifier. After determining the current operating mode, the controller calls the parameter requirement combination corresponding to the current operating mode. The parameter requirement combination is a set of parameter requirements pre-set for different operating modes. The parameter requirement set includes at least two parameter requirements from the following: backlight drive current parameter, display brightness parameter, and temperature parameter.

[0047] After invoking the parameter requirement combination corresponding to the current operating mode, the controller forms a preset operating requirement for the current operating mode based on this parameter requirement combination. This preset operating requirement is not a single parameter requirement, but a set of operating requirements corresponding to the current operating mode. This set of operating requirements is used to define the operating state that the display module should meet or tend to meet in the current operating mode. In this embodiment, different operating modes correspond to different parameter requirement combinations; therefore, the preset operating requirements formed under different operating modes are different. Consequently, when the controller subsequently judges a deviation state, it does not rely on a uniform set of parameter requirements, but rather on the preset operating requirements corresponding to the current operating mode.

[0048] After determining the preset operating requirements corresponding to the current working mode, the controller acquires the operating parameters for the current observation period. These operating parameters include at least the backlight drive current parameter, display brightness parameter, and temperature parameter. The controller then compares the operating parameters for the current observation period with the preset operating requirements corresponding to the current working mode. During the comparison, the controller determines whether each operating parameter continuously deviates from its corresponding parameter requirement.

[0049] In this embodiment, the controller compares and judges the backlight driving current parameter, display brightness parameter, and temperature parameter respectively. If the backlight driving current parameter deviates from its corresponding parameter requirement at multiple consecutive sampling points during the current observation period, the controller determines a current deviation state; if the display brightness parameter deviates from its corresponding parameter requirement at multiple consecutive sampling points during the current observation period, the controller determines a brightness deviation state; if the temperature parameter deviates from its corresponding parameter requirement at multiple consecutive sampling points during the current observation period, the controller determines a temperature deviation state. The controller thus determines the deviation state of the display module during the current observation period.

[0050] In this embodiment, the deviation state is determined not based on the instantaneous anomaly of a single sampling point, but rather on the deviation of parameters corresponding to multiple consecutive sampling points within the current observation period. Therefore, the controller can distinguish between short-term fluctuations and continuous state changes. Furthermore, since the determination of the deviation state is based on the preset operating requirements corresponding to the current operating mode, the same changes in operating parameters can correspond to different deviation states in different operating modes.

[0051] For example, in a certain operating mode, the parameter requirements corresponding to the current operating mode impose corresponding requirements on both the display brightness and temperature parameters. After acquiring the display brightness and temperature parameters during the current observation period, the controller compares them respectively with the brightness and temperature parameter requirements corresponding to that operating mode. If the display brightness parameter deviates from its corresponding parameter requirement at multiple consecutive sampling points, and the temperature parameter deviates from its corresponding parameter requirement at multiple consecutive sampling points, the controller determines the brightness deviation state and the temperature deviation state respectively. If only a single sampling point shows a temperature anomaly, and subsequent sampling points recover to the corresponding parameter requirement range, the controller does not directly determine the change at that single sampling point as a temperature deviation state.

[0052] like Figure 3 As shown, after the controller has determined at least several of the current deviation state, brightness deviation state, and temperature deviation state, the controller further generates an operating state deviation result. In this embodiment, the operating state deviation result is not a separate record of a single deviation state, but rather a combined expression of at least two deviation states within the same observation period. Therefore, the controller can treat the continuous state changes of the display module within that observation period as a whole state for subsequent judgment.

[0053] The controller first extracts at least two deviation states from the identified deviation states. These at least two deviation states refer to deviation states that coexist within the same observation period and jointly reflect changes in the current operating state. These at least two deviation states may include current deviation state and brightness deviation state, brightness deviation state and temperature deviation state, or current deviation state and temperature deviation state; when all three deviation states are determined, the controller may also extract all three deviation states simultaneously.

[0054] After extracting at least two deviation states, the controller aggregates these deviation states into a single combined state. This aggregation means treating at least two common deviation states occurring within the same observation period as a basis for combining the same operational state changes, rather than separating each deviation state and processing them individually for subsequent judgment. The controller then generates an operational state deviation result based on this combined state. This operational state deviation result characterizes the overall deviation of the display module from the preset operational requirements corresponding to the current operating mode within the current observation period.

[0055] In this implementation, the controller does not immediately reach a final processing conclusion after determining a single deviation state. Instead, it first generates an operational state deviation result based on at least two deviation states, and then combines this result with the current operating mode in subsequent steps to determine the parameter correction requirement. This configuration allows the controller to incorporate multiple common state changes occurring within the current observation period into a single judgment basis, rather than directly adjusting parameters based solely on a single parameter change. Different combinations of deviation states can generate different operational state deviation results, and these different operational state deviation results can correspond to different parameter correction requirement states in subsequent judgments.

[0056] For example, when the controller has already determined brightness and temperature deviations, it extracts these two deviations and groups them into a combined state, then forms a category of operational state deviation results based on this combined state. Similarly, when the controller has already determined current, brightness, and temperature deviations, it extracts these three deviations and forms another category of operational state deviation results based on them. Thus, the controller can perform subsequent decisions for different combinations of state changes, rather than processing different state changes in the same way.

[0057] Furthermore, in some embodiments, when generating the operational state deviation result, the controller can establish a parameter recording table corresponding to the current observation period. The parameter recording table includes at least the sampling time, backlight drive current parameters, display brightness parameters, and temperature parameters. Based on the parameter recording table, the controller extracts the deviation states corresponding to multiple consecutive sampling points and generates the operational state deviation result accordingly.

[0058] For example, by using sampling time as an index to record backlight drive current parameters, display brightness parameters, and temperature parameters, a one-to-one correspondence can be established between various operating parameters within the same observation period. The controller identifies the brightness deviation and temperature deviation states corresponding to multiple consecutive sampling points in the parameter recording table, and forms the operating state deviation result for the current observation period based on these two deviation states.

[0059] Furthermore, the controller can also generate different operating state deviation results based on the combination of different deviation states in the parameter recording table.

[0060] For example, different types of state changes can be distinguished by combining brightness deviation states with temperature deviation states to form one type of operating state deviation result, and combining current deviation states with brightness deviation states to form another type of operating state deviation result. Therefore, the parameter recording table is not only used to store operating parameters, but also to support the extraction and combination of at least two deviation states and the formation of operating state deviation results.

[0061] like Figure 4 As shown, after generating a deviation result in the operating state, the controller further generates a parameter correction requirement determination result, and based on this, formulates a parameter correction strategy and executes parameter correction processing. The controller first calls the parameter correction determination condition corresponding to the current operating mode. The parameter correction determination condition is a judgment criterion pre-set for different operating modes. The judgment criterion is used to determine whether the deviation result in the current operating state allows the current operating parameters to be maintained, or whether at least one operating parameter needs to be adjusted.

[0062] The controller compares the current operating state deviation with the parameter correction criteria corresponding to the current operating mode. This comparison means the controller determines the overall deviation reflected by the current operating state deviation based on the applicable criteria under the current operating mode, rather than directly determining subsequent processing based solely on the operating state deviation, detached from the current operating mode. If the comparison result indicates that the current operating state deviation is still within the range where maintaining the current operating parameters is permissible, the controller determines the current parameter correction requirement state as a "maintain" state. If the comparison result indicates that the current operating state deviation has reached the point where at least one operating parameter should be adjusted, the controller determines the current parameter correction requirement state as a "correction" state. The controller then generates a parameter correction requirement determination result based on the determined parameter correction requirement state.

[0063] In this implementation, the same deviation from the operating state can lead to different parameter correction requirement states under different operating modes. That is, the controller does not directly execute parameter correction processing based solely on the deviation result; instead, it first calls the parameter correction judgment condition corresponding to the current operating mode, and then uses this judgment condition to determine the current deviation result, thereby forming a parameter correction requirement judgment result. Thus, processing requirements under different operating modes can be distinguished, and different types of state changes can correspond to different processing paths in subsequent processing.

[0064] For example, when the operating state deviation result generated by the controller is formed by a combination of brightness deviation and temperature deviation, in one operating mode, the controller determines, based on the parameter correction judgment conditions corresponding to that operating mode, that it is still permissible to maintain the current operating parameters, and thus determines the parameter correction requirement state as the hold state; in another operating mode, the controller determines, based on another set of parameter correction judgment conditions, that at least one operating parameter needs to be adjusted, and thus determines the parameter correction requirement state as the correction state. Therefore, the same operating state deviation result does not directly correspond to a fixed processing result, but requires further judgment based on the current operating mode.

[0065] In some implementations, different operating modes correspond to different parameter requirement combinations and parameter correction judgment conditions. After determining the current operating mode, the controller calls the parameter requirement combination corresponding to that current operating mode, compares the operating parameters within the current observation period, and, after forming an operating state deviation result, further calls the parameter correction judgment condition corresponding to that current operating mode. The parameter correction judgment condition specifies that, under the current operating mode, when the deviation state combination corresponding to the operating state deviation result meets the condition of maintaining the current operating parameters, the parameter correction requirement state is determined to be a "maintain" state; when the deviation state combination corresponding to the operating state deviation result meets the condition of adjusting at least one operating parameter, the parameter correction requirement state is determined to be a "correction" state. Thus, the parameter requirement combination supports the determination of the deviation state and the formation of the operating state deviation result, while the parameter correction judgment condition supports the determination of the parameter correction requirement state and the subsequent selection of parameter correction strategies.

[0066] Furthermore, in some implementations, the controller can save the parameter correction determination conditions together with the operating parameter records during the current observation period. The controller can also generate a determination record corresponding to the parameter correction requirement determination process. The determination record includes at least the current operating mode, the deviation result of the operating state, the parameter correction requirement status, and the corresponding processing conclusion.

[0067] For example, by recording "Current Operating Mode - Deviation Result of Operating State - Parameter Correction Requirement State - Processing Conclusion" in the judgment record, the controller can manage the judgment results under different operating modes. For the same deviation result of operating state, the controller can record the processing conclusion corresponding to the "maintain state" in one operating mode and the processing conclusion corresponding to the "correction state" in another operating mode. This allows for a clear reflection of how the same deviation result of operating state corresponds to different parameter correction requirement states under different operating modes.

[0068] Furthermore, the controller can also select a subsequent parameter correction strategy based on the determination record.

[0069] For example, the method of determining the working parameters to be corrected and the corresponding correction method based on the corresponding parameter correction requirement status in the judgment record can be used to make the parameter correction strategy correspond to the parameter correction requirement status formed in the current working mode.

[0070] After determining the parameter correction requirement, the controller identifies the operating parameters to be corrected based on the parameter correction requirement status. If the parameter correction requirement status is in a hold state, the controller maintains the current operating parameters unchanged. If the parameter correction requirement status is in a correction state, the controller further determines the operating parameters that need to be adjusted. The operating parameters to be corrected can be one or more of the following: backlight drive current parameters, display brightness parameters, and temperature parameters. After determining the operating parameters to be corrected, the controller determines the corresponding correction method based on the preset operating requirements corresponding to the current operating mode. The corresponding correction method indicates the adjustment action to be performed on the operating parameters to be corrected. The controller then formulates a parameter correction strategy based on the operating parameters to be corrected and the corresponding correction method.

[0071] After formulating a parameter correction strategy, the controller executes parameter correction processing according to the strategy. This parameter correction processing may include adjusting at least one operating parameter of the display module, including at least the backlight drive current parameter and the display brightness parameter; the temperature parameter is used to participate in the formation of operating state deviation results and the determination of parameter correction requirements. After executing the parameter correction processing, the controller ensures that the adjusted operating parameters meet or tend to meet the preset operating requirements corresponding to the current operating mode. Therefore, the controller does not process all operating parameters uniformly, but rather performs corresponding processing based on the current parameter correction requirement state and the current operating mode.

[0072] After performing parameter correction processing, the controller outputs the correction result corresponding to the parameter correction process. The correction result includes at least the operating parameters after parameter correction processing. The controller also determines the processed operating state based on the corrected operating parameters and outputs result information reflecting this operating state. Therefore, the controller outputs not simply parameter change values, but the correction result corresponding to the current operating state.

[0073] Therefore, this embodiment, based on the main process shown in Embodiment 1, further... Figure 2 The preset operating requirements and the formation process of the deviation state are shown. Figure 3 The process of forming the deviation result of the operating state shown and Figure 4 The parameter correction requirement determination result, parameter correction strategy, and parameter correction processing process are further explained in detail. Through the above explanation, those skilled in the art can further implement deviation judgment, requirement determination, strategy formation, and parameter correction processing corresponding to the current operating state based on Embodiment 1, and thereby form a correction processing result corresponding to the current working mode.

[0074] Example 3 like Figure 5As shown, this embodiment describes the structure and operation of an adaptive decision-making system for a display module. This system is applied to a display module. The system includes an operating parameter and operating mode acquisition module 501, a deviation result formation module 502, a parameter correction requirement determination module 503, a parameter correction strategy formation module 504, a parameter correction execution module 505, and a result output module 506. The operating parameter and operating mode acquisition module 501 is connected to the deviation result formation module 502. The operating parameter and operating mode acquisition module 501 is also connected to the parameter correction requirement determination module 503. The deviation result formation module 502 is connected to the parameter correction requirement determination module 503. The parameter correction requirement determination module 503 is connected to the parameter correction strategy formation module 504. The parameter correction strategy formation module 504 is connected to the parameter correction execution module 505. The parameter correction execution module 505 is connected to the result output module 506. Each module sequentially transmits operating parameters, working mode, deviation results of operating status, judgment results of parameter correction requirements, parameter correction strategy and correction processing results according to the above connection relationship, so as to complete the adaptive decision-making process of the display module in the current working state.

[0075] The operating parameter and working mode acquisition module 501 is used to acquire the working mode of the display module in its current working state, and to continuously acquire the operating parameters of the display module at a preset sampling period within a preset observation period. The operating parameters include at least backlight drive current parameters, display brightness parameters, and temperature parameters. The operating parameter and working mode acquisition module 501 can be connected to a current detection unit, a brightness detection unit, a temperature detection unit, and a mode input unit. The operating parameter and working mode acquisition module 501 acquires each operating parameter at a preset sampling period within the preset observation period, and provides the acquired operating parameters in chronological order to the deviation result formation module 502. The operating parameter and working mode acquisition module 501 also determines the current working mode and sends the current working mode to the deviation result formation module 502 and the parameter correction requirement determination module 503. Therefore, subsequent modules can perform corresponding processing based on the operating parameters and the current working mode within the same observation period.

[0076] The deviation result formation module 502 is used to form an operating state deviation result based on the operating parameters. The deviation result formation module 502 receives the operating parameters and operating mode sent by the operating parameter and operating mode acquisition module 501. The deviation result formation module 502 first calls a pre-stored parameter requirement combination corresponding to the current operating mode as a preset operating requirement for the current operating mode. The preset operating requirements include at least two parameter requirements from the following: backlight drive current parameter, display brightness parameter, and temperature parameter. The deviation result formation module 502 then compares the operating parameters within the current observation period with the preset operating requirements to determine at least several of the current deviation state, brightness deviation state, and temperature deviation state. The deviation result formation module 502 then extracts at least two deviation states, aggregates the extracted at least two deviation states into the same combined state, and forms an operating state deviation result based on this combined state. The deviation result formation module 502 sends the formed operating state deviation result to the parameter correction requirement determination module 503. Therefore, the deviation result generation module 502 does not generate a result based on a single change of a single parameter, but rather generates a deviation result based on the preset operating requirements corresponding to the current working mode and multiple deviation states within the current observation period.

[0077] The parameter correction requirement determination module 503 is used to form a parameter correction requirement determination result based on the deviation result of the operating state and the working mode. The parameter correction requirement determination module 503 receives the current working mode sent by the operating parameter and working mode acquisition module 501, and the operating state deviation result sent by the deviation result formation module 502. The parameter correction requirement determination module 503 calls the parameter correction determination condition corresponding to the current working mode. The parameter correction determination condition is at least used to determine whether the current operating state deviation result corresponds to a maintain state or a correction state. The parameter correction requirement determination module 503 compares the current operating state deviation result with the called parameter correction determination condition. If the comparison result indicates that the current operating state deviation result still allows the current working parameters to be maintained, the parameter correction requirement determination module 503 determines the parameter correction requirement state to be a maintain state; if the comparison result indicates that the current operating state deviation result requires adjustment of at least one working parameter, the parameter correction requirement determination module 503 determines the parameter correction requirement state to be a correction state. The parameter correction requirement determination module 503 generates a parameter correction requirement determination result based on the determined parameter correction requirement status and sends the result to the parameter correction strategy formation module 504. Therefore, the parameter correction requirement determination module 503 does not directly determine subsequent processing based on the deviation result of the operating state, but rather generates a parameter correction requirement determination result based on the parameter correction determination conditions corresponding to the current operating mode. Thus, the same deviation result of the operating state can generate different parameter correction requirement determination results under different operating modes.

[0078] The parameter correction strategy forming module 504 is used to form a parameter correction strategy based on the parameter correction requirement determination result. The parameter correction strategy forming module 504 receives the parameter correction requirement determination result sent by the parameter correction requirement determination module 503, and forms a parameter correction strategy by combining it with preset operating requirements determined by pre-stored parameter requirement combinations corresponding to the current working mode. The preset operating requirements can be determined by pre-stored parameter requirement combinations in the system and can be called by the parameter correction strategy forming module 504. If the current parameter correction requirement state is a hold state, the parameter correction strategy forming module 504 forms a parameter correction strategy that holds the current working parameters. If the current parameter correction requirement state is a correction state, the parameter correction strategy forming module 504 further determines the working parameters to be corrected and determines the corresponding correction method for the working parameters to be corrected according to the preset operating requirements corresponding to the current working mode. The parameter correction strategy forming module 504 then forms a parameter correction strategy based on the working parameters to be corrected and the corresponding correction method, and sends the parameter correction strategy to the parameter correction execution module 505. Therefore, the parameter correction strategy forming module 504 does not directly output abstract processing conclusions, but rather forms a parameter correction strategy corresponding to the current operating state based on the parameter correction requirement judgment results and the preset operating requirements corresponding to the current working mode.

[0079] The parameter correction execution module 505 performs parameter correction processing according to a parameter correction strategy. The parameter correction execution module 505 receives a parameter correction strategy sent by the parameter correction strategy formation module 504, and adjusts at least one operating parameter of the display module according to the parameter correction strategy. The at least one operating parameter includes at least a backlight drive current parameter and a display brightness parameter; the temperature parameter is used to participate in the formation of the operating state deviation result and the determination of parameter correction requirements. If the parameter correction strategy requires maintaining the current operating parameters, the parameter correction execution module 505 maintains the current operating parameters unchanged. If the parameter correction strategy requires adjusting at least one operating parameter, the parameter correction execution module 505 performs corresponding adjustments to the corresponding operating parameters, ensuring that the processed operating parameters meet or tend to meet the preset operating requirements corresponding to the current operating mode. After completing the processing, the parameter correction execution module 505 forms a correction processing result and sends the result to the result output module 506.

[0080] The result output module 506 is used to output the correction processing result corresponding to the parameter correction processing. The result output module 506 receives the correction processing result sent by the parameter correction execution module 505 and outputs the working parameters after parameter correction processing. The result output module 506 also determines the operating status of the display module relative to the current working mode and the preset operating requirements after parameter correction processing based on the working parameters after parameter correction processing, and outputs result information reflecting this operating status. Therefore, the result output module 506 outputs not simply parameter change values, but the working parameters after parameter correction processing and their corresponding operating status result information.

[0081] In this embodiment, the operating parameter and working mode acquisition module 501, the deviation result formation module 502, the parameter correction requirement determination module 503, the parameter correction strategy formation module 504, the parameter correction execution module 505, and the result output module 506 can be implemented by the controller executing a stored program. When the controller executes the stored program, it completes the functions corresponding to each module. Optionally, the deviation result formation module 502 and the parameter correction requirement determination module 503 can be integrated into the same processing unit; the parameter correction strategy formation module 504 and the parameter correction execution module 505 can also be integrated into the same processing unit. Further, the operating parameter and working mode acquisition module 501 can be connected to the current detection circuit, the brightness detection circuit, the temperature detection circuit, and the mode input interface; the parameter correction execution module 505 can be connected to the backlight driving unit and the brightness adjustment unit; the temperature detection result is used to participate in the deviation state determination, the operating state deviation result formation, and the parameter correction requirement determination.

[0082] The system described in this embodiment corresponds to the method process described in the foregoing embodiments. Specifically, the deviation result formation module 502 can implement the combination in Embodiment 2. Figure 2 and Figure 3 The described process includes the formation of preset operating requirements, the determination of deviation states, and the formation of operating state deviation results; the parameter correction requirement determination module 503, the parameter correction strategy formation module 504, and the parameter correction execution module 505 can realize the combination of the two embodiments in Example 2. Figure 4 The description includes the formation of parameter correction requirement determination results, parameter correction strategy formation, and parameter correction processing procedures; the result output module 506 can realize the output process of the processed running status result information. Therefore, this embodiment illustrates the implementation method of the adaptive decision-making process of the display module from the perspective of system structure.
