Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display device and a method for controlling the temperature of the display device. Background Technology

[0002] In high ambient temperatures, the internal temperature of display devices will also be relatively high. Furthermore, during use, some internal hardware modules of the display device continuously generate heat, causing the internal temperature to rise steadily. This problem is particularly pronounced for display devices such as shop window advertising screens and outdoor displays installed in enclosed environments.

[0003] When the internal temperature of a display device is high, the high temperature can easily cause the internal hardware of the display device to fail, resulting in the display device malfunctioning, unable to display content normally, and even shortening the lifespan of the display device. Summary of the Invention

[0004] This application provides a display device and a temperature control method for the display device, which can take corresponding overheat protection measures according to the internal temperature of the display device, improve the failure problem of internal hardware of the display device caused by high temperature, reduce the failure rate caused by high temperature, and extend the service life of the display device.

[0005] In a first aspect, some embodiments provide a display device, including:

[0006] The monitor is configured to display the interface.

[0007] A temperature sensor is configured to collect and display the internal temperature of the device.

[0008] At least one controller, connected to both the display and the temperature sensor, is configured to:

[0009] Acquire the first internal temperature collected by the temperature sensor;

[0010] When the first internal temperature is within the first preset temperature range, the first overheat protection measure corresponding to the first preset temperature range is executed.

[0011] During the execution of the first overheat protection measure, the second internal temperature is acquired by the temperature sensor.

[0012] If the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure shall be implemented.

[0013] Wherein, the exit temperature corresponding to the first preset temperature range is less than the minimum temperature value of the first preset temperature range, and the overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure.

[0014] Secondly, some embodiments also provide a temperature control method for a display device, the method comprising:

[0015] Obtain the first internal temperature of the display device;

[0016] When the first internal temperature is within the first preset temperature range, the first overheat protection measure corresponding to the first preset temperature range is executed.

[0017] During the execution of the first overheat protection measure, the second internal temperature of the display device is obtained;

[0018] If the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure shall be implemented.

[0019] Wherein, the exit temperature corresponding to the first preset temperature range is less than the minimum temperature value of the first preset temperature range, and the overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure.

[0020] Thirdly, some embodiments provide a temperature control device for a display device, the device comprising:

[0021] The first acquisition module is used to acquire the first internal temperature of the display device;

[0022] The first execution module is used to execute the first overheat protection measure corresponding to the first preset temperature range when the first internal temperature is located in the first preset temperature range among the preset temperature ranges.

[0023] The second acquisition module is used to acquire the second internal temperature of the display device during the execution of the first overheat protection measure;

[0024] The second execution module is used to execute a second overheat protection measure when the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range; wherein the exit temperature corresponding to the first preset temperature range is lower than the minimum temperature value of the first preset temperature range, and the overheat protection capability of the second overheat protection measure is lower than the overheat protection capability of the first overheat protection measure.

[0025] Fourthly, some embodiments provide a computer device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program to implement the steps of the method provided in the first aspect.

[0026] Fifthly, some embodiments provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps in the above-described method embodiments.

[0027] Sixthly, some embodiments provide a computer program product including a computer program that, when executed by a processor, implements the steps in the above-described method embodiments.

[0028] The display device and its temperature control method provided in this application acquire a first internal temperature collected by a temperature sensor. When the first internal temperature falls within a first preset temperature range, a first overheat protection measure corresponding to that first preset temperature range is executed. Different preset temperature ranges correspond to different overheat protection measures. Executing the first overheat protection measure corresponding to the first preset temperature range where the first internal temperature is located can improve the matching degree between the current internal temperature of the display device and the executed overheat protection measure, thereby improving the effectiveness of the overheat protection. During the execution of the first overheat protection measure, a second internal temperature collected by a temperature sensor is acquired. When the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, a second overheat protection measure is executed. The overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure. Therefore, after the temperature drops, the executed overheat protection measure is adjusted, and the adjusted second overheat protection measure has a lower overheat protection capability than the first overheat protection measure, thus maintaining the matching degree between the current internal temperature of the display device and the executed overheat protection measure, ensuring the effectiveness of the overheat protection. Because of the effectiveness of overheat protection, the possibility of internal hardware failure in the display device can be reduced, the failure rate caused by high temperature can be decreased, the normal display of content can be guaranteed as much as possible, and the service life of the display device can be extended. Moreover, the exit temperature corresponding to the first preset temperature range is lower than the minimum temperature value of the first preset temperature range. When the second internal temperature fluctuates near the minimum temperature value of the first preset temperature range, the overheat protection measure that needs to be executed is still the first overheat protection measure. There will be no frequent switching between the first and second overheat protection measures, which will further extend the service life of the display device. Attached Figure Description

[0058] In some embodiments, the communication device 220 is a component used to communicate with external devices or the server 400 according to various communication protocol types. The display device 200 may have multiple communication devices 220 depending on the supported communication methods. For example, when the display device 200 supports wireless network communication, it may have a communication device 220 with WiFi functionality. When the display device 200 supports Bluetooth connectivity, it needs to have a communication device 220 with Bluetooth functionality.

[0059] The communication device 220 enables the display device 200 to communicate with external devices or the server 400 via wireless or wired connections. Wired connections utilize data cables, interfaces, or other components to connect the display device 200 to external devices. Wireless connections utilize wireless signals or wireless networks.

[0064] In some embodiments, the user input interface 280 can be used to receive instructions from user input.

[0065] Figure 3 Provided for some embodiments of this application Figure 1 Hardware configuration block diagram of the central control device. (Example) Figure 3 As shown, the control device 100 may include: a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0066] The control device 100 is configured to control the display device 200, and to receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200.

[0067] In some embodiments, the control device 100 may be an intelligent device. For example, the control device 100 may be equipped with various applications for controlling the display device 200 according to user needs.

[0068] In some embodiments, such as Figure 1 As shown, the mobile terminal 300 or other smart electronic devices can perform similar functions to the control device 100 after installing the application of the control display device 200.

[0069] The controller 110 includes a processor 112, RAM 113, ROM 114, a communication interface 130, and a communication bus. The controller 110 is used to control the operation of the control device 100, as well as the communication and cooperation between internal components and the external and internal data processing functions.

[0070] Under the control of the controller 110, the communication interface 130 enables communication of control signals and data signals with the display device 200. The communication interface 130 may include at least one of other near-field communication modules such as WiFi chip 131, Bluetooth module 132, and NFC module 133.

[0071] User input / output interface 140, wherein the input interface includes at least one of other input interfaces such as microphone 141, touchpad 142, sensor 143, and button 144.

[0072] In some embodiments, the control device 100 includes at least one of a communication interface 130 and an input / output interface 140. The control device 100 is configured with the communication interface 130, such as a WiFi, Bluetooth, or NFC module, which can encode user input commands via WiFi, Bluetooth, or NFC protocols and send them to the display device 200.

[0073] The memory 190 is used to store various operating programs, data, and applications for driving and controlling the control device 100 under the control of the controller. The memory 190 can also store various control signal instructions input by the user.

[0074] The power supply 180 is used to provide operating power support for the various components of the control device 100 under the control of the controller.

[0075] In some embodiments, the display device 200 may run an operating system to enable user interaction. An operating system is a computer program that manages and controls the hardware and software resources of the display device 200. The operating system can (control the display device) provide a user interface, allowing users to interact with the display device 200 and supporting the running of various applications.

[0076] It should be noted that the operating system can be a native operating system based on a specific operating platform, a third-party operating system that is deeply customized based on a specific operating platform, or an independent operating system specifically developed for display devices.

[0077] An operating system can be divided into different modules or levels based on the functions it implements, for example... Figure 4 As shown, in some embodiments, the system is divided into four layers, from top to bottom: the Applications layer (referred to as the "Application Layer"), the Application Framework layer (referred to as the "Framework Layer"), the System Library layer, and the Kernel layer.

[0078] In some embodiments, the application layer provides services and interfaces for applications, enabling the display device 200 to run applications and interact with the user based on the applications. The application layer may contain at least one application, which may be a built-in Windows program, system settings program, or clock program of the operating system; or it may be an application developed by a third-party developer. In specific implementations, the application packages in the application layer are not limited to the examples above.

[0079] The framework layer provides application programming interfaces (APIs) and a programming framework for applications. The application framework layer includes predefined functions. It acts as a central processing unit, determining the actions taken by applications within the application layer. Through the API, applications can access system resources and obtain system services during execution.

[0080] like Figure 4As shown, the application framework layer in this embodiment includes a view system, managers, and content providers. The view system designs and implements the application's interface and interactions, and includes lists, grids, text boxes, and buttons. The managers include at least one of the following modules: an activity manager for interacting with all running activities in the system; a location manager for providing system services or applications with access to system location services; a package manager for retrieving various information related to application packages currently installed on the device; a notification manager for controlling the display and clearing of notification messages; and a window manager for managing icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0081] In some embodiments, the Activity Manager manages the lifecycle of individual applications and common navigation and back functions, such as controlling application exit, opening, and back actions. The Window Manager manages all window programs, such as obtaining the screen size, determining if a status bar is present, locking the screen, capturing the screen, and controlling changes to the display window, such as shrinking the display window, shaking the display, or distorting the display.

[0082] In some embodiments, the system runtime library layer can provide support for the framework layer. When the framework layer is used, the operating system runs the instruction library contained in the system runtime library layer, such as the C / C++ instruction library, to implement the functions to be performed by the framework layer.

[0083] In some embodiments, the kernel layer is a functional layer situated between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. For example, ... Figure 4 As shown, hardware drivers can be configured in the kernel layer. The kernel layer can contain at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0084] In high ambient temperatures (e.g., above 35 degrees Celsius), the internal temperature of a display device can easily rise continuously during use. Excessive internal temperature can cause internal hardware failure, leading to display malfunctions and the inability to display content properly, such as advertisements. Furthermore, the failure of internal hardware due to high temperatures will shorten the lifespan of the display device.

[0085] To address the aforementioned problems, in some exemplary embodiments, a temperature control method for a display device is provided. This method is applied to a display device 200, specifically to a controller 250 of the display device 200. See also... Figure 5 The method includes:

[0086] S510 acquires the first internal temperature collected by the temperature sensor.

[0087] The temperature sensor is located inside the display device and is connected to the controller. The temperature sensor is used to periodically or in real time collect the internal temperature of the display device.

[0088] S520, when the first internal temperature is within the first preset temperature range, execute the first overheat protection measure corresponding to the first preset temperature range.

[0089] For example, four preset temperature ranges are pre-set: preset temperature range [T1, T2), preset temperature range [T2, T3), preset temperature range [T3, T4), and preset temperature range [T4, positive infinity]. Where T1... <T2<T3<T4。

[0090] Specifically, different preset temperature ranges correspond to different overheat protection levels, and different overheat protection levels correspond to different overheat protection measures. For example, the preset temperature range [T1, T2) corresponds to overheat protection level 1, the preset temperature range [T2, T3) corresponds to overheat protection level 2, the preset temperature range [T3, T4) corresponds to overheat protection level 3, and the preset temperature range [T4, positive infinity) corresponds to overheat protection level 4. Overheat protection level 1 corresponds to overheat protection measure 1, overheat protection level 2 corresponds to overheat protection measure 2, overheat protection level 3 corresponds to overheat protection measure 3, and overheat protection level 4 corresponds to overheat protection measure 4. Overheat protection levels 1, 2, 3, and 4 increase sequentially, and the overheat protection capabilities of overheat protection measures 1, 2, 3, and 4 increase sequentially.

[0091] For example, if the first internal temperature is within a preset temperature range [T2, T3), then the first preset temperature range is the preset temperature range [T2, T3), and the first overheat protection measure is overheat protection measure 2.

[0092] Among them, overheat protection measure 1 may include starting the cooling fan to operate at the first speed setting, which is a low speed setting.

[0093] Among them, overheat protection measure 2 may include starting the cooling fan to operate at the second speed, which is the high speed setting.

[0094] Among them, overheat protection measure 3 may include starting the cooling fan to run at level 2, turning off the automatic backlight adjustment function, and gradually reducing the current backlight brightness of the monitor to a preset ratio of the current backlight brightness (e.g., 50%).

[0095] Among them, overheat protection measure 3 may include starting the cooling fan to run at level 2, turning off the automatic backlight adjustment function, popping up a temperature alarm prompt box, turning off the screen display and audio output, and entering a sleep protection state.

[0096] S530 acquires the second internal temperature from the temperature sensor during the execution of the first overheat protection measure.

[0097] That is, during the execution of the first overheat protection measure, the internal temperature is also acquired in real time from the temperature sensor. In order to distinguish it from the first internal temperature before the execution of the first overheat protection measure, the internal temperature acquired here is called the second internal temperature.

[0098] Of course, if the second internal temperature is higher than the first internal temperature, for example, if the first internal temperature is within the preset temperature range [T2,T3) and the second internal temperature is within the preset temperature range [T3,T4), it means that the first overheat protection measure is ineffective. In this case, the first overheat protection measure needs to be replaced with the overheat protection measure corresponding to the preset temperature range [T3,T4).

[0099] As can be seen, this embodiment implements a graded temperature protection mechanism. Compared with the traditional single overheat protection scheme, the overheat protection measures adopted are more adapted to the current internal temperature of the display device.

[0100] S540, if the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure is executed.

[0101] Wherein, the exit temperature corresponding to the first preset temperature range is less than the minimum temperature value of the first preset temperature range, and the overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure.

[0102] As can be seen, after the first overheat protection measure was taken, the second internal temperature of the display device decreased, indicating that the first overheat protection measure was effective. When the second internal temperature drops below the exit temperature corresponding to the first preset temperature range, the first overheat protection measure is replaced with a second overheat protection measure, which has a weaker overheat protection capability, because the second overheat protection measure is more suitable for the current second internal temperature.

[0103] Different preset temperature ranges have corresponding exit temperatures, and the exit temperature of each preset temperature range is less than the minimum temperature value of that preset temperature range. For example, the exit temperature of the preset temperature range [T1, T2) is less than T1, the exit temperature of the preset temperature range [T2, T3) is less than T2, the exit temperature of the preset temperature range [T3, T4) is less than T3, and the exit temperature of the preset temperature range [T4, positive infinity) is less than T4.

[0104] For example, if the first internal temperature is within the first preset temperature range [T4, positive infinity), and after the overheat protection measure 4 is executed as the first overheat protection measure for a period of time, the second internal temperature drops to a temperature lower than the exit temperature of the first preset temperature range, then the overheat protection level is adjusted to overheat protection level 1, and the overheat protection measure 1 corresponding to overheat protection level 1 is used as the second overheat protection measure, and the second overheat protection measure is executed.

[0105] It is evident that the process of switching overheat protection measures does not necessarily require a step-by-step reduction, making the selection of the second overheat protection measure more flexible.

[0106] For example, if the first internal temperature is within the first preset temperature range [T3, T4), and after overheat protection measure 3 is implemented as the first overheat protection measure for a period of time, if the second internal temperature drops below the exit temperature of the first preset temperature range but is greater than the exit temperature corresponding to the preset temperature range [T2, T3), then the overheat protection level is adjusted to overheat protection level 2 corresponding to the preset temperature range [T2, T3), and overheat protection measure 2 corresponding to overheat protection level 2 is implemented as the second overheat protection measure. Then, during the implementation of the second overheat protection measure, the third internal temperature of the display device is collected in real time. If the third internal temperature drops below the exit temperature of the preset temperature range [T2, T3) but is greater than the exit temperature corresponding to the preset temperature range [T1, T2), then the overheat protection level is adjusted to overheat protection level 1 corresponding to the preset temperature range [T1, T2), and overheat protection measure 1 corresponding to overheat protection level 1 is implemented as the third overheat protection measure. Next, during the execution of the third overheat protection measure, the fourth internal temperature of the display device is collected in real time. If the fourth internal temperature drops to a temperature lower than the exit temperature of the preset temperature range [T1, T2), it indicates that the fourth internal temperature of the display device is normal and can exit the overheat protection state. The various configuration parameters of the display device will be restored to the corresponding parameter values ​​before the first overheat protection measure was taken.

[0107] As can be seen, S540 may specifically include: when the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range and the second internal temperature is higher than the exit temperature corresponding to the second preset temperature range, executing the second overheat protection measure corresponding to the second preset temperature range; the first preset temperature range and the second preset temperature range are adjacent preset temperature ranges, so that the overheat protection measures can be gradually reduced to avoid the internal temperature of the display device from rising.

[0108] In this embodiment, a first internal temperature is acquired from a temperature sensor. If the first internal temperature falls within a first preset temperature range, a first overheat protection measure corresponding to that first preset temperature range is executed. Different preset temperature ranges correspond to different overheat protection measures. Executing the first overheat protection measure corresponding to the first preset temperature range where the first internal temperature is located can improve the matching degree between the current internal temperature of the display device and the executed overheat protection measure, thereby improving the effectiveness of overheat protection. During the execution of the first overheat protection measure, a second internal temperature is acquired from a temperature sensor. If the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, a second overheat protection measure is executed. The overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure. It can be seen that after the temperature drops, the executed overheat protection measure is adjusted, and the overheat protection capability of the adjusted second overheat protection measure is lower than that of the first overheat protection measure, thereby maintaining the matching degree between the current internal temperature of the display device and the executed overheat protection measure, ensuring the effectiveness of overheat protection. Because of the effectiveness of overheat protection, the possibility of internal hardware failure in the display device can be reduced, the failure rate caused by high temperature can be decreased, the normal display of content can be guaranteed as much as possible, and the service life of the display device can be extended. Moreover, the exit temperature corresponding to the first preset temperature range is lower than the minimum temperature value of the first preset temperature range. When the second internal temperature fluctuates near the minimum temperature value of the first preset temperature range, the overheat protection measure that needs to be executed is still the first overheat protection measure. There will be no frequent switching between the first and second overheat protection measures, which will further extend the service life of the display device.

[0109] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided, in which the execution steps of the second overheat protection measure in S540 are refined.

[0110] See Figure 6 The detailed implementation steps for the second overheat protection measure include:

[0111] S610, obtain the temperature offset corresponding to the first preset temperature range.

[0112] The temperature offset can be understood as the offset between the minimum temperature value of the first preset temperature range and the exit temperature.

[0113] In one optional implementation, the temperature offset corresponding to the preset temperature range is positively correlated with the overheat protection capability of the overheat protection measures corresponding to the preset temperature range.

[0114] That is, the stronger the overheat protection capability of the overheat protection measures, the greater the temperature deviation within the preset temperature range.

[0115] For example, the temperature offset corresponding to the preset temperature range [T1,T2), the temperature offset corresponding to the preset temperature range [T2,T3), the temperature offset corresponding to the preset temperature range [T3,T4), and the temperature offset corresponding to the preset temperature range [T4,positive infinity) increase sequentially.

[0116] In the above implementation, the preset temperature range with stronger overheat protection capability corresponds to a larger temperature offset. Thus, when the second internal temperature of the display device is higher, the requirement to adjust the first overheat protection measure with stronger overheat protection capability to the second overheat protection measure with weaker overheat protection capability is more stringent, which is conducive to quickly reducing the second internal temperature, i.e., rapid cooling.

[0117] S620, determine the exit temperature corresponding to the first preset temperature range based on the difference between the minimum temperature value of the first preset temperature range and the temperature offset.

[0118] That is, the difference between the minimum temperature value of the first preset temperature range and the temperature offset is directly used as the exit temperature corresponding to the first preset temperature range.

[0119] S630, if the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure is executed.

[0120] In this embodiment, the exit temperature corresponding to the first preset temperature range is determined based on the minimum temperature value of the first preset temperature range and the temperature offset corresponding to the first preset temperature range. Different preset temperature ranges are set with different temperature offsets, which can make the switching between different overheat protection measures different in terms of strictness, thereby ensuring the rationality of the switching between different overheat protection measures.

[0121] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided, in which the execution steps of the second overheat protection measure in S540 are refined.

[0122] See Figure 7 The detailed implementation steps for the second overheat protection measure include:

[0123] S710, if the duration for which the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range reaches a preset duration, the second overheat protection measure is executed.

[0124] In one optional implementation, different preset temperature ranges correspond to different preset durations, and the preset duration is positively correlated with the overheat protection capability.

[0125] That is, the longer the preset time corresponds to the preset temperature range with stronger overheat protection capability, the more powerful the overheat protection capability. In this case, when the first preset temperature range is a high temperature range, the second internal temperature needs to be lower than the exit temperature corresponding to the first preset temperature range for a longer preset time before the first overheat protection measure can be switched to the second overheat protection measure. This longer execution time of the first overheat protection measure can improve the cooling effect on the display device.

[0126] In this embodiment, switching from the first overheat protection measure to the second overheat protection measure requires not only that the second internal temperature be lower than the first preset temperature range, but also that this temperature range be maintained for a preset duration. This prevents incorrect switching of the overheat protection measure due to inaccurate data collection of the second internal temperature. Furthermore, if the internal temperature of the display device rises after switching to the second overheat protection measure, it needs to be switched back to the first overheat protection measure. This results in frequent switching of overheat protection measures, impacting the lifespan of the display device.

[0127] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided, in which the execution steps of the second overheat protection measure in S540 are refined.

[0128] See Figure 8 The detailed implementation steps for the second overheat protection measure include:

[0129] S810, determine the rate of temperature decrease of the second internal temperature within the first preset temperature range.

[0130] That is, when the first overheat protection measure is started, the second internal temperature is acquired in real time, and the rate of temperature drop is calculated in real time based on the acquired second internal temperature and the second internal temperature when the first overheat protection measure is started.

[0131] S820, if the temperature drop rate is not lower than the preset rate and the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure is executed.

[0132] Understandably, if the temperature drop rate is not lower than the preset rate, it indicates that the cooling effect of the first overheat protection measure is relatively good, and the cooling can be achieved in a short time to meet the cooling requirements. Therefore, if the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, or if the duration of the second internal temperature being lower than the exit temperature corresponding to the first preset temperature range reaches the preset duration, the second overheat protection measure will be executed.

[0133] In this embodiment, if the rate of temperature decrease of the second internal temperature within the first preset temperature range is not lower than the preset rate, and if the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, then the second overheat protection measure is executed. Therefore, when it is determined that the first overheat protection measure needs to be switched to the second overheat protection measure based on the second internal temperature and the exit temperature corresponding to the first preset temperature range, the first overheat protection measure has already achieved effective reduction. After switching to the second overheat protection measure, the possibility of temperature rebound is relatively small.

[0134] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided. In this optional embodiment, based on the above S810 and S820, the temperature control method is refined to include an overheat protection measure upgrade step.

[0135] See Figure 9 The upgrade steps for overheat protection measures include:

[0136] S910, if the rate of temperature drop is lower than the preset rate, executes the third overheat protection measure.

[0137] Among them, the overheat protection capability of the third overheat protection measure is higher than that of the first overheat protection measure.

[0138] In this embodiment, the rate of temperature decrease of the second internal temperature within the first preset temperature range is lower than the preset rate, indicating that the cooling effect of the first overheat protection measure is poor. Not only can it not be switched to the second overheat protection measure, which has even weaker cooling capacity, but it is also necessary to switch to the third overheat protection measure, which has a stronger cooling capacity, to accelerate cooling. At this point, the relationship between the second internal temperature and the minimum temperature value of the preset temperature range corresponding to the third overheat protection measure is not considered. Even if the second internal temperature is less than the minimum temperature value of the preset temperature range corresponding to the third overheat protection measure, it is still necessary to switch from the first overheat protection measure to the third overheat protection measure. This can effectively improve the problem of poor cooling capacity caused by unreasonable settings of overheat protection measures in each preset temperature range.

[0139] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided, in which the execution steps of the second overheat protection measure in S540 are refined.

[0140] See Figure 10 The detailed implementation steps for the second overheat protection measure include:

[0141] S1010, if the first overheat protection measure is not the overheat protection measure with the lowest overheat protection capability among the overheat protection measures corresponding to each preset temperature range, and the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, the second overheat protection measure shall be executed.

[0142] For example, if the first overheat protection measure is overheat protection measure 2, overheat protection measure 3 or overheat protection measure 4, then the second overheat protection measure is executed when the second internal temperature is less than the exit temperature corresponding to the first preset temperature range, or when the duration of the second internal temperature being less than the exit temperature corresponding to the first preset temperature range reaches a preset duration.

[0143] S1020, if the first overheat protection measure is the overheat protection measure with the lowest overheat protection capability among the overheat protection measures corresponding to each preset temperature range, and the second internal temperature is less than the exit temperature corresponding to the first preset temperature range, then stop executing any overheat protection measure.

[0144] S1010 and S1020 have no specific order.

[0145] For example, if the first overheat protection measure is overheat protection measure 1, then if the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, or if the duration of the second internal temperature being lower than the exit temperature corresponding to the first preset temperature range reaches a preset duration, it indicates that the second internal temperature of the display device is relatively low at this time, and no overheat protection measure needs to be executed. Therefore, any overheat protection measure is stopped.

[0146] In this embodiment, depending on whether the first overheat protection measure is the overheat protection measure with the lowest overheat protection capability among the overheat protection measures corresponding to each preset temperature range, it can be determined whether it is necessary to exit the overheat protection state when the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range, or when the duration of the second internal temperature being lower than the exit temperature corresponding to the first preset temperature range reaches a preset duration, so as to avoid increasing the overheat protection cost due to the display device being in the overheat protection state all the time.

[0147] Based on the technical solutions provided in the above embodiments, an optional embodiment is provided, which provides a temperature control method for a display device. (See [link to previous embodiment]). Figure 11 The method includes:

[0148] S1101, acquire the first internal temperature collected by the temperature sensor.

[0149] S1102, when the first internal temperature is within the first preset temperature range, execute the first overheat protection measure corresponding to the first preset temperature range.

[0150] S1103, during the execution of the first overheat protection measure, acquires the second internal temperature collected by the temperature sensor.

[0151] S1104, obtain the temperature offset corresponding to the first preset temperature range.

[0152] The temperature offset corresponding to the preset temperature range is positively correlated with the overheat protection capability of the overheat protection measures corresponding to the preset temperature range.

[0153] S1105, determine the exit temperature corresponding to the first preset temperature range based on the difference between the minimum temperature value and the temperature offset of the first preset temperature range.

[0154] S1106, determine whether the first overheat protection measure is the overheat protection measure with the lowest overheat protection capability among the overheat protection measures corresponding to each preset temperature range; if yes, execute S1111, otherwise execute S1107.

[0155] S1107, determine the rate of temperature decrease of the second internal temperature within the first preset temperature range.

[0156] S1108, determine whether the temperature drop rate is lower than the preset rate; if yes, execute S1110, otherwise execute S1109.

[0157] S1109, if the duration for which the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range reaches a preset duration, and the second internal temperature is higher than the exit temperature corresponding to the second preset temperature range, the second overheat protection measure corresponding to the second preset temperature range is executed.

[0158] The first preset temperature range and the second preset temperature range are adjacent preset temperature ranges.

[0159] Different preset temperature ranges correspond to different preset durations, and the preset duration is positively correlated with the overheat protection capability.

[0160] Wherein, the exit temperature corresponding to the first preset temperature range is less than the minimum temperature value of the first preset temperature range, and the overheat protection capability of the second overheat protection measure is lower than that of the first overheat protection measure.

[0161] S1110, implement the third overheat protection measure.

[0162] Among them, the overheat protection capability of the third overheat protection measure is higher than that of the first overheat protection measure.

[0163] S1111, if the duration for which the second internal temperature is lower than the exit temperature corresponding to the first preset temperature range reaches a preset duration, stop executing any overheat protection measure.
