Description

Technical Field

[0001] This application belongs to the field of electronic technology, specifically relating to a method, apparatus, electronic device, and storage medium for detecting abnormalities in a liquid crystal module. Background Technology

[0002] With the development of display technology, liquid crystal modules (LCMs) have become increasingly popular in electronic devices due to their advantages such as high image quality, low power consumption, wide viewing angle, thinness, and fast response. However, LCMs may malfunction during use, and if these malfunctions are not repaired promptly, they may be damaged.

[0003] Currently, electronic devices can determine if an LCM (Liquid Crystal Display) is malfunctioning by detecting its power consumption. Specifically, the electronic device can detect the current of the device when the LCM screen is off and the current of the device when the LCM screen is at its brightest. The difference between these two values ​​is then used as the LCM's power consumption value. By comparing this power consumption value with a power consumption threshold, it can be determined whether the LCM is malfunctioning.

[0004] However, since electronic devices typically run multiple services in the background, if an abnormality occurs in the background service when the electronic device detects LCM power consumption, such as service crash, excessive file I / O operations, or other resource consumption, it will lead to an increase in system power consumption, resulting in a higher detected current. This will affect the accuracy of power consumption calculation, thus leading to lower accuracy in detecting LCM abnormalities by the electronic device. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, electronic device, and storage medium for detecting abnormalities in liquid crystal modules (LCMs), which can improve the accuracy of electronic devices in detecting LCM abnormalities.

[0006] In a first aspect, embodiments of this application provide a method for detecting anomalies in a liquid crystal module. The method includes: upon detecting a power-on event, running an operating system using a single thread and loading a liquid crystal module display driver; the liquid crystal module display driver is used to control the brightness of the screen liquid crystal module of an electronic device; determining a first power consumption value of the screen liquid crystal module using the liquid crystal module display driver; and determining whether the screen liquid crystal module is abnormal based on the first power consumption value and a first power consumption threshold.

[0007] Secondly, embodiments of this application provide a liquid crystal module anomaly detection device, which includes an execution module, a determination module, and a judgment module. The execution module, upon detecting a power-on event, runs an operating system using a single thread and loads a liquid crystal module display driver, which controls the brightness of the screen liquid crystal module of the electronic device. The determination module determines a first power consumption value corresponding to the screen liquid crystal module based on the liquid crystal module display driver loaded by the execution module. The judgment module determines whether the screen liquid crystal module is abnormal based on the first power consumption value determined by the determination module and a first power consumption threshold.

[0008] Thirdly, embodiments of this application provide an electronic device including a processor and a memory, wherein the memory stores programs or instructions executable on the processor, and the programs or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0009] Fourthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0010] Fifthly, embodiments of this application provide a chip, the chip including a processor and a communication interface, the communication interface being coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0011] In a sixth aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method described in the first aspect.

[0012] In this embodiment, upon detecting a power-on event, the operating system can be run in a single thread, and the LCD module display driver can be loaded. This LCD module display driver controls the brightness of the screen LCD module of the electronic device. Then, a first power consumption value corresponding to the screen LCD module can be determined based on the LCD module display driver. Based on the first power consumption value and a first power consumption threshold, it can be determined whether the screen LCD module is abnormal. In this solution, since the operating system is run in a single thread upon detecting a power-on event, there is no need to run the operating system in a multi-threaded manner. This allows fewer services to run in the background, thereby reducing the probability of service anomalies and reducing the problem of high current in the electronic device caused by service anomalies. Furthermore, the LCD module display driver can be loaded without loading additional drivers, avoiding the problem of unstable current in the electronic device caused by loading too many drivers. This allows for accurate detection of the electronic device's current. Thus, the LCM power consumption value calculated from the detected electronic device current is more accurate, thereby improving the accuracy of judging LCM anomalies through LCM power consumption value.

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The terms "at least one," "at least one," etc., in this application refer to any one, any two, or a combination of two or more of the included objects. For example, at least one of a, b, and c can mean: "a," "b," "c," "a and b," "a and c," "b and c," and "a, b, and c," where a, b, and c can be single or multiple. Similarly, "at least two" refers to two or more, and its meaning is similar to that of "at least one."

[0030] The following description, in conjunction with the accompanying drawings, details the liquid crystal module anomaly detection method, apparatus, electronic device, and storage medium provided in this application through specific embodiments and application scenarios.

[0031] The embodiments of this application can be applied to scenarios where power consumption detection is performed on the LCM in electronic devices to determine whether the LCM is abnormal.

[0032] The following uses some specific scenarios from the embodiments of this application as examples to illustrate the liquid crystal module anomaly detection method provided in the embodiments of this application.

[0033] Scenario 1: Assume the user's phone has an LCM screen, and the LCM within this screen malfunctions. After the user powers on the phone, the operating system runs in a single thread during the boot process, loading the LCM display driver. The LCM driver then controls the screen brightness. A platform power meter detects the phone's current at both the lowest and highest screen brightness levels, calculating the LCM power consumption based on the difference. After calculating the power consumption, the phone compares it to a power threshold, determining an LCM anomaly. Upon booting, the phone displays a prompt message advising the user to visit an authorized service center for repair as soon as possible.

[0034] Scenario 2: Assume a smartwatch is equipped with an LCM screen. When the user restarts the watch, it can run the operating system in a single thread, loading only the necessary LCM display driver. The LCM display driver then controls the screen brightness. A power meter is used to measure the current at the LCM screen's lowest and highest brightness levels to calculate the LCM power consumption. After detection, the system compares the LCM power consumption value with a set normal threshold. If abnormal power consumption is detected, the smartwatch will alert the user via vibration or a pop-up notification, recommending that the user visit an authorized service center for inspection and maintenance.

[0035] It should be noted that the above scenarios 1 and 2 are merely exemplary examples of some scenarios that may be applied to the embodiments of this application. In actual implementation, the embodiments of this application can also be applied to any possible scenarios requiring abnormal detection of liquid crystal modules. The embodiments of this application are not limited here.

[0036] This application provides a method, apparatus, electronic device, and storage medium for detecting abnormalities in a liquid crystal module (LCD). When a power-on event is detected, the electronic device can run the operating system in a single thread, eliminating the need for multi-threaded operation. This allows fewer services to run in the background, reducing the probability of service failures and minimizing high current consumption caused by such failures. Furthermore, the electronic device can load the LCD module display driver without additional drivers, avoiding current instability caused by excessive driver loading. This allows for accurate current detection. Consequently, the LCM power consumption value calculated from the detected current is more accurate, improving the accuracy of identifying LCM abnormalities based on LCM power consumption.

[0037] The execution subject of the liquid crystal module anomaly detection method provided in this application embodiment can be a liquid crystal module anomaly detection device, which can be an electronic device, or a functional module or functional entity in the electronic device. The following uses an electronic device as an example to illustrate the technical solution provided in this application embodiment.

[0038] Figure 1 A flowchart of a liquid crystal module anomaly detection method provided in an embodiment of this application is shown, as follows: Figure 1 As shown, the liquid crystal module anomaly detection method provided in this application embodiment may include the following steps 201 to 203.

[0039] Step 201: Upon detecting a power-on event, the electronic device runs the operating system using a single thread and loads the LCD module display driver.

[0040] In this embodiment of the application, the above-mentioned liquid crystal module display driver is used to control the brightness of the liquid crystal module of the screen of the electronic device.

[0041] In this embodiment, the above-mentioned liquid crystal module display driver is also called an LCM display driver, which can change the luminous intensity of the liquid crystal display module by controlling the backlight of the LCM screen.

[0042] In this embodiment of the application, the screen may be referred to as an LCM screen or a liquid crystal screen, which is a screen composed of liquid crystal modules.

[0043] In this embodiment of the application, the operating system is system software that manages the hardware and software resources of electronic devices and is used for interaction between users and electronic devices.

[0044] In this embodiment, the aforementioned power-on event is an event that triggers the electronic device to start the operating system and enter the power-on state. This power-on state is the running state in which the electronic device successfully starts the operating system and can perform user interaction and execute applications. The opposite state is the power-off state, which refers to the electronic device being in a turned-off state. In this state, the operating system of the electronic device is not running, and the hardware components and functions of the electronic device are inactive.

[0045] Optionally, in this embodiment of the application, the aforementioned power-on event may include, but is not limited to, any of the following situations:

[0046] (1) User operation: When the electronic device is powered off, the user can manually start the electronic device by pressing the power button or other means.

[0047] (2) Power-on startup: When the electronic device is powered on and then powered on, it will start automatically.

[0048] (3) Restart: The electronic device restarts in the event of a software update, system failure, or when the user manually selects to restart.

[0049] (4) Timed power-on: When the electronic device is powered off, it automatically powers on based on a preset time.

[0050] (5) External signal triggering: When the electronic device is powered off, it can be activated in response to an external signal, such as a network wake-up or a sensor trigger.

[0051] It should be noted that the single-threaded approach described above refers to using only one execution thread to process tasks within a single process. In single-threaded mode, the operating system of an electronic device operates linearly, with all tasks executed sequentially, avoiding the complexity and potential problems associated with multi-threaded concurrency.

[0052] Optionally, in this embodiment of the application, during the startup process of the electronic device, before the kernel of the operating system is loaded and running when a power-on event is detected, the electronic device can enter the LCM power consumption detection mode. In this mode, the electronic device can use only one thread to start the operating system and load only the necessary drivers for detecting LCM power consumption, such as the LCM display driver, without loading other unnecessary drivers. This can ensure that the current of the electronic device can be kept stable when power consumption detection is performed, and avoid interference with the current stability caused by running multiple services in multiple threads and loading too many drivers.

[0053] Step 202: Determine the first power consumption value of the screen LCD module using the LCD module display driver.

[0054] In this embodiment, the first power consumption value is the electrical energy consumed by the LCM in the LCM screen during operation, that is, the electrical energy consumed by the content displayed on the LCM screen. The LCM power consumption value depends on factors such as the brightness of the LCM screen, the displayed content, and the screen refresh rate.

[0055] Optionally, in this embodiment of the application, the electronic device can control the brightness of the LCM screen through the LCM display driver, and detect the current value of the electronic device under the brightness through the platform power meter, thereby calculating the LCM power consumption value based on the detected current value.

[0056] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 2 As shown, step 202 above can be specifically implemented through steps 202a to 202c below.

[0057] Step 202a: The electronic device uses the LCD module display driver to control the LCD module of the screen to the first brightness, and uses the platform power meter to detect the first current value within the first time period.

[0058] In this embodiment, the first current value is the current value of the electronic device when the screen liquid crystal module is at the first brightness.

[0059] Optionally, in this embodiment, the first brightness can be a lower brightness level, such as the lowest brightness state, that is, the brightness of the LCM screen is adjusted to a level close to the lowest, that is, the backlight of the LCM screen is turned off, so that the luminous intensity of the liquid crystal display module is close to the lowest, and the LCM screen appears to be close to a black screen.

[0060] It is understandable that the electronic device controls the LCM screen to be in the lowest brightness state, that is, the electronic device turns off the LCM screen.

[0061] In this embodiment, the first duration is the duration for which the current value is measured when the LCM screen is in its lowest brightness state.

[0062] Optionally, in this embodiment, the first duration can be the default duration of the electronic device or a duration preset by the user. For example, the first duration can be 0.5 seconds, 1 second, or 2 seconds, etc. The specific duration can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0063] Optionally, in this embodiment of the application, the electronic device can adjust the brightness of the LCM screen to a near-minimum level through the LCM display driver, so that the LCM screen appears to be in a near-black state, so that the power consumption of the LCM screen is close to 0. Then, the electronic device can detect the current value multiple times, for example 5 times, through the platform power meter within a set first time period, and calculate the average value of these values ​​to obtain a stable and accurate first current value.

[0064] For example, assuming the first duration is 1 second and the number of detections is 5, the electronic device can detect the current value 5 times within 1 second. Assuming the current values ​​detected by the electronic device are 80 milliampere (mA), 82mA, 81mA, 83mA, and 80mA, the electronic device can calculate the average of these 5 current values ​​to obtain the first current value = (80+82+81+83+80) / 5 = 81.2mA.

[0065] Step 202b: The electronic device uses the LCD module display driver to control the LCD module of the screen to the second brightness, and uses the platform power meter to detect the second current value within the first time period.

[0066] In this embodiment of the application, the second brightness is greater than the first brightness.

[0067] Optionally, in this embodiment of the application, the second brightness can be a higher brightness level, such as the highest brightness, that is, the brightness of the LCM screen is adjusted to a level close to the highest.

[0068] In this embodiment, the second current value is the current value of the electronic device when the screen liquid crystal module is at the second brightness.

[0069] Optionally, in this embodiment, the electronic device can continuously display a dynamic image or interface at a fixed refresh rate for a first duration, or the electronic device can continuously display a static image or interface at a fixed refresh rate for a first duration, such as continuously displaying the main screen icon of the electronic device at a refresh rate of 60 Hz. By maintaining a fixed refresh rate and the same display content, the electronic device can accurately and stably detect the second current value of the LCM screen liquid crystal module at the second brightness.

[0070] Optionally, in this embodiment of the application, the electronic device can adjust the brightness of the LCM screen to the highest level through the LCM display driver so that the power consumption of the LCM screen is close to the highest level. Then, the electronic device can detect the current value multiple times, such as 5 times, through the platform power meter within a set first time period, and calculate the average value of these values ​​to obtain a stable and accurate second current value.

[0071] For example, assuming the first duration is 1 second and the number of detections is 5, the electronic device can detect the current value 5 times within 1 second. Assuming the current values ​​detected by the electronic device are 480mA, 482mA, 481mA, 482mA, and 480mA, the electronic device can calculate the average of these 5 current values ​​to obtain the second current value = (480+482+481+482+480) / 5 = 481mA.

[0072] Step 202c: The electronic device determines the first power consumption value based on the first current value and the second current value.

[0073] In this embodiment of the application, the power consumption value mentioned above is also called the LCM power consumption value, which is the power consumption value of the LCM.

[0074] It should be noted that the power consumption value is the product of the current value and the voltage value. In this embodiment, since the voltage change of the electronic device is small and only the current value changes significantly, the difference between the first current value and the second current value, i.e. the current value used by the LCM, is used to represent the magnitude of the first power consumption value.

[0075] Optionally, in this embodiment of the application, the electronic device can use the platform power meter to use the difference between the first current value and the second current value as the first power consumption value.

[0076] For example, assuming the first current value is 81.2mA and the second current value is 481mA, the electronic device can calculate the first power consumption value = 481 - 81.2 = 399.8mA using the platform's power meter.

[0077] In this way, electronic devices can control the brightness of the LCM screen through the LCM display driver, and detect the current value of the electronic device at that brightness through the platform power meter. Thus, by controlling the brightness of the LCM screen and excluding other variables, the influence of the brightness change of the LCM screen on the current value of the electronic device can be known, thereby accurately calculating the LCM power consumption value.

[0078] Step 203: The electronic device determines whether the screen LCD module is abnormal based on the first power consumption value and the first power consumption threshold.

[0079] In this embodiment of the application, the first power consumption threshold is a standard for judging whether the LCM is abnormal. It is used to compare with the first power consumption value to judge whether the LCM in the LCM screen is abnormal.

[0080] Optionally, in this embodiment, the first power consumption threshold can be the default value of the electronic device or a value preset by the user. For example, the first power consumption threshold can be 400mA, 410mA, or 420mA, etc. The specific threshold can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0081] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 3 As shown, step 203 above can be specifically implemented through step 203a below.

[0082] Step 203a: When the first power consumption value is less than the first power consumption threshold, the electronic device determines that the screen LCD module is in a normal state.

[0083] For example, assuming the power consumption threshold is 400mA and the first power consumption value is 399.8mA, the electronic device can determine that 399.8mA is less than 400mA, that is, the first power consumption value is less than the power consumption threshold, and the electronic device can determine that the screen LCD module is in normal condition.

[0084] In this way, if the first power consumption value is less than the power consumption threshold, the electronic device can consider that the LCM has no abnormal power consumption, that is, the LCM is working well and there is no abnormality. Thus, the electronic device can quickly and accurately determine that the screen LCD module is in normal condition when the first power consumption value is less than the power consumption threshold, which improves the efficiency and accuracy of the electronic device in determining the normality of the LCM.

[0085] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 4 As shown, step 203 can be implemented through steps 203b to 203d below.

[0086] Step 203b: If the first power consumption value is greater than or equal to the first power consumption threshold, the electronic device determines the second power consumption value of the screen liquid crystal module using the liquid crystal module display driver after a second time period.

[0087] Optionally, in this embodiment, the second duration can be the default duration of the electronic device or a duration preset by the user. For example, the second duration can be 1 second, 2 seconds, or 3 seconds, etc. The specific duration can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0088] Optionally, in this embodiment of the application, when the first power consumption value is greater than or equal to the first power consumption threshold, the electronic device can, after a second period of time, reuse the liquid crystal module display driver to obtain the power consumption value of the LCM to obtain the second power consumption value, and then compare the second power consumption value with the first power consumption threshold.

[0089] Optionally, in this embodiment of the application, when the second power consumption value is less than the first power consumption threshold, the electronic device can determine that the liquid crystal module is in a normal state.

[0090] For example, assuming the power consumption threshold is 400mA, the first power consumption value is 401mA, and the second duration is 3 seconds, after the electronic device determines that the first power consumption value is greater than the first power consumption threshold for 3 seconds, it can re-obtain the second power consumption value using the LCD module display driver. Assuming the second power consumption value is 399.6mA, the electronic device can determine that 399.6mA is less than 400mA, that is, the second power consumption value is less than the first power consumption threshold, and the electronic device can determine that the screen LCD module is in a normal state.

[0091] Step 203c: When the second power consumption value is greater than or equal to the first power consumption threshold, the electronic device determines the third power consumption value of the screen liquid crystal module using the liquid crystal module display driver after a third time period.

[0092] Optionally, in this embodiment, the third duration can be the default duration of the electronic device or a duration preset by the user. For example, the third duration can be 1 second, 2 seconds, or 3 seconds, etc. The specific duration can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0093] Optionally, in this embodiment of the application, when the second power consumption value is greater than or equal to the first power consumption threshold, the electronic device can, after a third time period, reuse the liquid crystal module display driver to obtain the power consumption value of the LCM to obtain the third power consumption value, and then compare the third power consumption value with the first power consumption threshold.

[0094] Optionally, in this embodiment of the application, when the third power consumption value is less than the first power consumption threshold, the electronic device can determine that the liquid crystal module is in a normal state.

[0095] For example, assuming the power consumption threshold is 400mA, the second power consumption value is 402mA, and the third duration is 2 seconds, the electronic device can re-obtain the third power consumption value by utilizing the LCD module display driver after determining that the second power consumption value is greater than the first power consumption threshold for 2 seconds. Assuming the third power consumption value is 399mA, the electronic device can determine that 399mA is less than 400mA, that is, the third power consumption value is less than the first power consumption threshold, and the electronic device can determine that the screen LCD module is in a normal state.

[0096] Step 203d: If the third power consumption value is greater than or equal to the first power consumption threshold, the electronic device determines that the screen LCD module is in an abnormal state.

[0097] For example, assuming the power consumption threshold is 400mA, the second power consumption value is 402mA, and the third duration is 2 seconds, the electronic device can re-obtain the third power consumption value based on the first driver after determining that the second power consumption value is greater than the first power consumption threshold for 2 seconds. Assuming the third power consumption value is 403mA, the electronic device can determine that 403mA is greater than 400mA, that is, the third power consumption value is greater than the first power consumption threshold. Therefore, the electronic device can determine that the screen LCD module is in an abnormal state.

[0098] Optionally, in this embodiment, if the first power consumption value detected for the first time is greater than or equal to the first power consumption threshold, the electronic device can detect the LCM power consumption value a second time after a second time interval to obtain a second power consumption value, and continue to compare the second detected power consumption value, i.e., the second power consumption value, with the first power consumption threshold. If the second power consumption value is also greater than or equal to the first power consumption threshold, the electronic device can detect the LCM power consumption value a third time after a third time interval to obtain a third power consumption value, and continue to compare the third detected power consumption value, i.e., the third power consumption value, with the first power consumption threshold. This process continues, and if the first power consumption value is greater than or equal to the first power consumption threshold, the electronic device can continue to detect the LCM power consumption value until the detected LCM power consumption value is less than the first power consumption threshold, or the number of detections is greater than or equal to a preset number.

[0099] Optionally, in this embodiment, the number of detections can be the default value of the electronic device or a value preset by the user. For example, the number of detections can be 3. The specific number can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0100] Optionally, in this embodiment of the application, if the electronic device detects that the LCM power consumption value is less than the first power consumption threshold when the number of detections is less than the preset number, the electronic device can determine that there is no abnormality in the LCM; if the electronic device detects that the LCM power consumption value is greater than or equal to the first power consumption threshold, the electronic device can continue to detect the LCM power consumption value after a certain period of time and continue to compare the LCM power consumption value with the first power consumption threshold.

[0101] Optionally, in this embodiment of the application, if the electronic device detects that the LCM power consumption value is less than the power consumption threshold when the number of detections is greater than or equal to the preset number of detections, the electronic device can determine that the LCM is not abnormal; if the electronic device detects that the LCM power consumption value is greater than or equal to the power consumption threshold, the electronic device can determine that the LCM is abnormal.

[0102] In this way, electronic devices can more accurately determine whether the LCM is abnormal by repeatedly detecting the LCM power consumption value at different time periods, avoiding misjudgment caused by short-term power consumption fluctuations, and improving the accuracy of electronic devices in judging LCM abnormalities.

[0103] This application provides a method for detecting anomalies in a liquid crystal module. When a power-on event is detected, the operating system can run in a single thread, eliminating the need for multi-threaded operation. This allows fewer services to run in the background, reducing the probability of service anomalies and mitigating the problem of high current consumption in electronic devices caused by such anomalies. Furthermore, a first driver, including the LCM display driver and the platform power meter, can be loaded without requiring additional drivers. This avoids the current instability caused by loading too many drivers, thus enabling accurate detection of the electronic device's current and calculation of the LCM power consumption value corresponding to the LCM screen. This improves the accuracy of LCM power consumption detection in electronic devices.

[0104] Optionally, in the embodiments of this application, combined with Figure 4 ,like Figure 5 As shown, after step 203d above, the liquid crystal module anomaly detection method provided in this application embodiment further includes the following step 301.

[0105] Step 301: The electronic device outputs a prompt message indicating an abnormality in the LCD module of the screen.

[0106] In this embodiment of the application, the above-mentioned prompt information is used to indicate that the screen liquid crystal module is in an abnormal state.

[0107] Optionally, in this embodiment of the application, if the electronic device determines that the screen liquid crystal module is in an abnormal state, the electronic device can display a prompt message through the LCM screen.

[0108] Optionally, in this embodiment of the application, the above-mentioned prompt information may be displayed in the top area of ​​the LCM screen, or the above-mentioned prompt information may be displayed in the form of a window in the LCM screen.

[0109] For example, taking a mobile phone as an electronic device, such as Figure 6 As shown, assuming the phone detects an LCM abnormality during the power-on process, the phone can display a prompt message 11 in the top area 10 of the LCM screen.

[0110] For example, such as Figure 7 As shown, assuming the phone detects an LCM abnormality during the power-on process, the phone can display a first window 12 on the LCM screen and display a prompt message 11 in the first window 12.

[0111] Optionally, in this embodiment of the application, when the electronic device has multiple LCM screens, the above-mentioned prompt information is used to indicate that the LCD module displaying the prompt information is in an abnormal state.

[0112] In this way, electronic devices can alert users to LCM malfunctions by displaying prompts, thus reminding users to have the LCM repaired in a timely manner and avoiding more serious failures caused by users not being aware of the problem.

[0113] Optionally, in the embodiments of this application, combined with Figure 5 ,like Figure 8 As shown, after step 301 above, the liquid crystal module anomaly detection method provided in this application embodiment further includes the following step 401.

[0114] Step 401: When the screen LCD module is in normal condition, the electronic device writes the fourth power consumption value to the first partition.

[0115] In this embodiment of the application, the fourth power consumption value is the maximum value among the first power consumption value, the second power consumption value, and the third power consumption value.

[0116] In this embodiment, the first partition is also referred to as the backup partition, which is used to store data generated during device operation. Even if the electronic device is powered off or restarted, the data in the backup partition can still be retained, and the electronic device can reread this data after restarting.

[0117] Optionally, in this embodiment of the application, when the electronic device determines that the LCM corresponding to the LCM screen is normal based on the obtained LCM power consumption value, the electronic device can write the maximum value of the obtained LCM power consumption value as the fourth power consumption value into the backup partition, so that in the subsequent calculation of the first power consumption threshold, the electronic device can refer to the power consumption of the LCM in the normal state.

[0118] For example, if an electronic device determines that the LCM is normal based on the first power consumption value, the electronic device can use the first power consumption value as the fourth power consumption value.

[0119] For example, assuming the preset number of iterations is 4, and the first power consumption threshold is 400mA, the electronic device obtains an LCM power consumption value of 400.2mA in the first iteration, which is greater than the first power consumption threshold. The electronic device then obtains the LCM power consumption value in the second iteration. If the second LCM power consumption value is 401mA, which is greater than the first power consumption threshold, the electronic device then obtains the LCM power consumption value in the third iteration. If the third LCM power consumption value is 400.5mA, which is greater than the first power consumption threshold, the electronic device then obtains the LCM power consumption value in the fourth iteration. If the fourth LCM power consumption value is 399.8mA, which is less than the first power consumption threshold, then the electronic device can use the maximum value among the four obtained LCM power consumption values ​​as the fourth power consumption value, i.e., the electronic device can use 401mA as the fourth power consumption value and write it to the first partition.

[0120] In this way, electronic devices can record the maximum power consumption value to provide data support for subsequent calculation of the first power consumption threshold, thereby improving the accuracy of electronic devices in judging LCM anomalies.

[0121] Optionally, in this embodiment, the first power consumption threshold is stored in the first partition. Exemplarily, the liquid crystal module anomaly detection method provided in this embodiment further includes steps 501 to 503 as described below.

[0122] Step 501: The electronic device obtains the fifth power consumption value from the first partition.

[0123] In this embodiment, the fifth power consumption value is the highest historical power consumption value of the screen LCD module.

[0124] Optionally, in this embodiment of the application, the first partition stores at least one LCM power consumption value.

[0125] Optionally, in this embodiment of the application, after each power-on, if the screen LCD module is in a normal state, the electronic device can obtain the LCM power consumption value written during the current power-on process from the first partition, and compare the LCM power consumption value with the historical highest power consumption value when the historical LCM power consumption value was detected before the current power-on, and take the maximum value of the two LCM power consumption values ​​as the historical highest power consumption value, that is, the fifth power consumption value.

[0126] For example, suppose the electronic device is in a powered-off state. The first partition of the electronic device stores the highest historical power consumption value of 398mA when the LCM power consumption value was detected. At this time, the user operates the electronic device to turn it on. Suppose that during this power-on process, the electronic device determines that the screen LCD module is in a normal state and writes the fourth power consumption value of 399mA into the first partition. Then, after the electronic device is powered on, the electronic device can obtain the fourth power consumption value of 399mA and the highest power consumption value of 398mA among the historical LCM power consumption values ​​before this power-on from the first partition, and take the maximum value of the two LCM power consumption values, 399mA, as the highest historical power consumption value, that is, the fifth power consumption value.

[0127] Optionally, in this embodiment of the application, the electronic device can store all historically detected LCM power consumption values ​​in the first partition. After each power-on, if the LCM corresponding to the LCM screen is normal, the electronic device can use the maximum value among all LCM power consumption values ​​stored in the first partition as the fifth power consumption value.

[0128] For example, suppose that during a power-on process, the electronic device determines that the LCM corresponding to the LCM screen is normal. Assume that after powering on, the first partition stores the following LCM power consumption values: LCM power consumption value A: 395mA, LCM power consumption value B: 400mA, LCM power consumption value C: 398mA, and LCM power consumption value D: 402mA, where LCM power consumption value D is the LCM power consumption value detected during this power-on process. The electronic device can use the maximum value among all LCM power consumption values ​​stored in the first partition, i.e., 402mA, as the fifth power consumption value.

[0129] Optionally, in this embodiment of the application, the electronic device can store the historically detected LCM power consumption values ​​to a cloud server. The cloud server can collect information such as the electronic device's model, machine identification (ID), frame rate, usage duration, failure rate, and LCM power consumption values ​​to calculate the first power consumption threshold. Examples of this information are shown in Table 1.

[0130] Table 1

[0131]

[0132] Among them, C lcm_c The fifth power consumption value, C worning This is the first power consumption threshold. After each power-on, if the LCM corresponding to the LCM screen is normal, the electronic device can compare the fourth power consumption value written to the first partition during this power-on process with the LCM power consumption value stored in the cloud server, and take the maximum value as the fifth power consumption value.

[0133] Step 502: The electronic device determines the second power consumption threshold based on the fifth power consumption value and the historical usage information of the screen LCD module.

[0134] Optionally, in this embodiment of the application, the historical usage information of the above-mentioned screen LCD module includes at least one of the following: model, machine ID, frame rate, usage duration, and failure rate.

[0135] Optionally, in this embodiment of the application, the second power consumption threshold can be calculated using the following formula (1):

[0136] C worning =T·V+C lcm_c ·(1+P·X)+Y Formula (1)

[0137] Among them, C worning The second power consumption threshold is denoted by T, where T is the usage duration in days. V is the usage duration coefficient, which represents the normal wear and tear of the LCM as usage time increases. This coefficient can be preset based on the LCM screen model, for example, it can be 0.01. C lcm_cThis is the fifth power consumption value. P is the defect rate, which can be 0.001 for example. X is the defect rate coefficient, which defaults to 1. Y is the controllable offset, which can be 2 for example, meaning that an error of 2mA is considered to be within the normal acceptable range and can be adjusted according to the actual situation.

[0138] For example, assuming the usage duration T is 3 days, the usage duration coefficient V = 0.01, and the fifth power consumption value C... lcm_c =455.6mA, defect rate P=0.001, defect rate coefficient X=1, controllable offset Y=2mA, then the electronic device can substitute these values ​​into formula (1) to calculate and obtain the second power consumption threshold C. worning =3·0.01+455.600·(1+0.001·1)+2=458.0856mA, meaning that if the power consumption of the LCM detected during the next power-on process is greater than or equal to this value, the electronic device can display a prompt message on the LCM screen.

[0139] Step 503: The electronic device updates the first power consumption threshold in the first partition using the second power consumption threshold.

[0140] Optionally, in this embodiment of the application, after the electronic device calculates the second power consumption threshold, it can use the second power consumption threshold to update the first power consumption threshold in the first partition, so that the electronic device can use the second power consumption threshold to compare with the detected LCM power consumption value during the next power-on process to determine whether the LCM is abnormal.

[0141] Optionally, in this embodiment, the electronic device can automatically and seamlessly detect LCM anomalies during user operation. Specifically, the electronic device can calculate a power consumption threshold based on the LCM's power consumption during user operation, combined with information such as LCM screen-on time, LCM single-unit failure rate, and LCM frame rate, and then upload this threshold to the cloud. The electronic device can continuously monitor the LCM power consumption value and compare it with the threshold to promptly detect LCM faults. This detection mechanism not only allows for real-time detection of LCM anomalies in the user's electronic device during use but also enables the screening of substandard LCM devices at the factory using cloud-based user data, thereby preventing these substandard LCM devices from entering the market and impacting the user experience.

[0142] In this way, electronic devices can update the power consumption threshold in a timely manner based on historically detected LCM power consumption values ​​and usage information after each power-on. That is, electronic devices can dynamically adjust the power consumption threshold by combining information such as LCM usage time, thereby improving the accuracy of electronic devices in judging whether the LCM is abnormal by using power consumption thresholds.

[0143] This application provides a method for detecting abnormalities in a liquid crystal module. Figure 9 A flowchart of a liquid crystal module anomaly detection method provided in an embodiment of this application is shown. This method can be applied to electronic devices. Figure 9 As shown, the liquid crystal module anomaly detection method provided in this application embodiment may include the following steps 10 to 15.

[0144] Step 10: Upon detecting a power-on event, the electronic device enters the LCM power consumption detection mode.

[0145] In this embodiment of the application, under the above-mentioned LCM power consumption detection mode, the electronic device runs the operating system using a single thread and loads the LCM display driver.

[0146] Step 11: The electronic device detects the LCM power consumption value based on the LCM display driver and the platform power meter.

[0147] In this embodiment of the application, the above-mentioned LCM power consumption value is the difference between the current value of the electronic device when the LCM screen brightness is at its highest and the current value of the electronic device when the LCM screen brightness is at its lowest.

[0148] Step 12: The electronic device determines whether the LCM is abnormal based on the LCM power consumption value and power consumption threshold.

[0149] If the electronic device determines that the LCM is abnormal, the electronic device performs step 15 below; if the electronic device determines that the LCM is not abnormal, the electronic device performs step 13 below.

[0150] Step 13: After powering on, the electronic device compares the LCM power consumption value with the historical LCM power consumption value to obtain the maximum LCM power consumption value.

[0151] In this embodiment of the application, the aforementioned historical LCM power consumption value is at least one LCM power consumption value detected by the electronic device when it determines that the LCM is normal during the historical detection process. The aforementioned maximum LCM power consumption value is the maximum value among the at least one LCM power consumption values ​​detected by the electronic device when it determines that the LCM is normal during the historical detection process.

[0152] Step 14: The electronic device updates the power consumption threshold based on the maximum LCM power consumption value and the historical usage information of the LCM.

[0153] Step 15: The electronic device displays a prompt message on the LCM screen.

[0154] In this embodiment of the application, the above-mentioned prompt information is used to indicate an LCM abnormality corresponding to the LCM screen.

[0155] In this embodiment, the electronic device can automatically and accurately detect the stable and accurate power consumption current value of the LCM in real time without disassembling the device during user operation, and without affecting the user experience. Furthermore, the electronic device can dynamically adjust the alarm threshold by combining information such as LCM usage time, LCM unit failure rate, and LCM frame rate. When abnormal power consumption is detected, the electronic device can promptly remind the user and suggest going to the after-sales service center for repair, thereby improving the reliability of the electronic device and the user experience, and reducing potential losses caused by LCM abnormalities.

This application uses the liquid crystal module anomaly detection device executing the liquid crystal module anomaly detection method as an example to illustrate the liquid crystal module anomaly detection device provided in this application.

[0158] Figure 10 A possible structural schematic diagram of a liquid crystal module anomaly detection device involved in some embodiments of this application is shown. For example... Figure 10 As shown, the LCD module anomaly detection device 70 may include: an execution module 71, a determination module 72, and a judgment module 73.

[0159] The execution module 71 is used to run the operating system in a single thread and load the LCD module display driver when a power-on event is detected; the LCD module display driver is used to control the brightness of the screen LCD module of the electronic device.

[0160] The aforementioned determining module 72 is used to determine the first power consumption value of the screen liquid crystal module based on the liquid crystal module display driver loaded by the execution module 71.

[0161] The aforementioned judgment module 73 is used to determine whether the screen LCD module is abnormal based on the first power consumption value and the first power consumption threshold determined by the determination module 72.

The execution module 71 is specifically configured to determine a first power consumption value based on the first current value detected by the determining module 72 and the second current value detected by the determining module 72 using the platform power meter.

[0163] In one possible implementation, the aforementioned judgment module 73 is specifically used to determine that the screen LCD module is in a normal state when the first power consumption value determined by the determination module 72 is less than the first power consumption threshold.

The judging module 73 is specifically configured to determine that the screen LCD module is in an abnormal state if the third power consumption value determined by the determining module 72 is greater than or equal to the first power consumption threshold.

[0165] In one possible implementation, the execution module 71 is further configured to, after the judgment module 73 determines whether the screen LCD module is abnormal based on the first power consumption value and the power consumption threshold, write the fourth power consumption value into the first partition when the screen LCD module is in a normal state. The fourth power consumption value is the maximum value among the first power consumption value, the second power consumption value and the third power consumption value.

[0168] This application provides a liquid crystal module (LCD) anomaly detection device. When a power-on event is detected, the device can run the operating system in a single thread, eliminating the need for multi-threaded operation. This allows fewer services to run in the background, reducing the probability of service failures and mitigating the problem of high current consumption caused by such failures. Furthermore, the device can load the LCD module display driver without loading additional drivers, avoiding current instability caused by excessive driver loading. This allows for accurate current detection. Consequently, the LCM power consumption value calculated from the detected current is more accurate, improving the accuracy of identifying LCM anomalies based on LCM power consumption.
