Technical Field

[0002] This article deals with display control technology. Background Art

[0003] The ink screen, also known as the ink screen, is made up of multiple bubble capsules, which are filled with black and white balls (charges) with positive and negative poles. By applying a special electric field above and below the airbags, the electric field forms a magnetic field, and under the action of the magnetic field, the black balls run up and the white balls run down, and black text on a white background is formed. In order for the page to display different patterns in the time domain by refreshing, different electric fields are applied, and the changes in the electric field are used to drive the changes in the screen. The change of the electric field is divided into three steps: erase, activate and display (hereinafter referred to as full refresh). All three processes require a certain magnetic field to be applied for a period of time to make the ball run to the target position.

[0029] Details

[0030] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0031] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0033] It is understood that the terms "first" and "second" used in this application are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0034] As used herein, the singular forms "a", "an", and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "comprises", "includes", or "having" specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

[0035] Water-ink screens, also known as electronic water-ink screens, are widely used in a variety of electronic devices. Since the refresh rate of the water-ink screen is limited by the speed at which the ball moves in the airbag, poor display effects may occur. For example, in a low-temperature environment, the charge may not return to its original position or return inaccurately, or it may take a long time to move to the target position, resulting in a significant reduction in the refresh rate of the water-ink screen or an inability to achieve a satisfactory display effect. The display effects and display performance of related products in low-temperature environments are somewhat lacking. Therefore, exploring more solutions to continuously improve the display effect of water-ink screens is the direction of effort for those skilled in the art.

[0036] For the technical improvement of the ink screen, on the one hand, we can explore the improvement of technical solutions related to the display principle, and on the other hand, we can start from the overall hardware solution of the electronic device to improve its actual operating environment, thereby improving the display effect and display performance. In some implementation plans, in order to perform temperature compensation, a new hardware unit is introduced into the electronic device to control its heat generation so that it can provide the heat required for temperature compensation for the ink screen. It can be seen that the introduction of new hardware units is bound to increase the complexity of the hardware design of electronic equipment, increase hardware costs, and increase the size of the equipment.

[0037] It has been found in practice that electronic devices containing processors will generate heat when the processor performs calculations or control tasks. As the number of tasks executed, the complexity or the intensity of the calculations increases, the heat generated will also increase. For example, when executing some real-time video processing, large-scale games, and high-intensity encryption and decryption tasks, the processor will generate more heat. The embodiment of the present application proposes a solution that uses the heat generated by the operation of the processor to achieve temperature compensation of the ink screen. When temperature compensation is required, in addition to the processor executing existing business / calculation / control tasks, one or more special setting tasks are additionally executed to generate more heat. The primary purpose of executing these one or more setting tasks is to increase the operating intensity or load of the processor, so that it generates more heat, which can then be transferred to the ink screen to increase the operating temperature of the ink screen.

[0038] It can be understood that when an electronic device is operating normally, the processor contained therein will also generate heat when performing related tasks according to business functions or device management functions. These tasks related to the business functions or device management functions of the electronic device itself are not executed to make the processor generate more heat. They are referred to as basic tasks in the embodiments of the present application. The primary purpose of executing the one or more set tasks is to increase the operating intensity or load of the processor, so that it generates more heat. They are unrelated to tasks related to other device business functions and management functions originally performed by the processor. When they are not executed, they do not affect the normal operation of the basic business functions and management functions of the electronic device. In the embodiments of the present application, they are referred to as additional heating tasks of the processor. In some exemplary embodiments, compared with the relevance of the basic tasks to business functions or management functions, the additional heating tasks performed by the one or more processors are also called "blank heating tasks."

[0039] An embodiment of the present application provides a method for controlling operating temperature, which is applied to an electronic device including an ink display and a processor, as shown in FIG1 , and includes:

[0040] Step 110: When a trigger event for controlling the working temperature of the ink display occurs, the processor starts or stops executing a set task according to the adjustment requirement of the working temperature of the ink display;

[0041] The heat generated when the processor executes the set task is used to maintain or increase the operating temperature of the ink screen.

[0042] It can be understood that the set task is an additional heat-generating task for the processor. When it is started and executed by the processor, the operating load or intensity of the processor is increased, and more heat can be generated compared to when the processor only performs basic tasks. This increased heat is conducted to the ink screen through the heat dissipation medium in the electronic device to increase or maintain its operating temperature; when the set task is stopped, that is, the increased load or intensity on the processor is reduced, and the corresponding newly generated heat during the operation of the processor is reduced, and the processor is restored to the operating state when the basic task is executed. It should be noted that the average amount of newly generated heat per unit time after starting to execute the set task compared to before starting is recorded as Q1; the average amount of reduced heat per unit time after stopping to execute the set task compared to before stopping is recorded as Q2, where the values ​​of Q1 and Q2 can be equal or different. In the temperature control scheme provided in the embodiment of the present application, the start-up execution of the set task is used to control the increase in heat generated by the processor operation compared to when the basic task is executed; the stop-execution of the set task is used to control the maintenance or reduction of the heat generated by the processor operation compared to when the basic task is executed; and the stop-execution of the set task is used to control the reduction in heat generated by the processor operation compared to when the basic task and the additional heat-generating task are executed.

[0043] In some exemplary embodiments, the setting task includes one or more of the following:

[0044] Encryption algorithm tasks, video data encoding and decoding tasks, and AI (Artificial Intelligence) algorithm tasks.

[0045] Optionally, the set task can also be other tasks. Selecting a task that can significantly increase the processing load or intensity of the processor as the set task can effectively increase the heat generated by the processor and achieve the goal of temperature compensation for the ink screen. The specific tasks are not limited to the aspects of the examples in the embodiments of this application.

[0046] In some exemplary embodiments, the set task includes one or more tasks, which may be one or more preset fixed tasks, or one or more tasks selected from a preset candidate task set to be started and executed as the set task.

[0047] In some exemplary embodiments, if the set tasks include multiple tasks, they can all be started or stopped at once; or, they can be started or stopped sequentially in multiple steps. During the multiple starts or stops, the decision on whether to continue starting or stopping can be made based on the real-time temperature detection results after each start or stop. The specific implementation method can be flexibly selected as needed and is not limited to a specific method.

[0048] In some exemplary embodiments, step 110 includes: when a water-ink screen operating temperature control trigger event occurs, the processor starts or stops executing the set task according to the water-ink screen's need to adjust the operating temperature and the processor's computing power reserve.

[0049] In some exemplary embodiments, as shown in FIG2 , the method further includes:

[0050] Step 100, obtain the computing power margin of the processor; or, when a trigger event of temperature control of the ink screen occurs, obtain the computing power margin of the processor.

[0051] Accordingly, step 110 includes: the processor starts or stops executing the set task according to the ink screen's need to adjust the working temperature and the computing power margin.

[0052] In some exemplary embodiments, the processor starts or stops executing a set task based on the need for the ink screen to adjust the operating temperature and the computing power margin, including:

[0053] When the adjustment of the working temperature of the ink display needs to be increased and the computing power margin is greater than a first set threshold, the processor starts executing the set task;

[0054] When the computing power margin is less than a second set threshold, the processor stops executing the set task;

[0055] The first set threshold is greater than the second set threshold.

[0056] It should be noted that in the embodiments of the present application, starting the execution of a set task is to start the execution of an unexecuted set task and enter the running state; stopping the execution of a set task is to stop the set task that has been started and is in the running state, stopping the execution and exiting the running state, so that it can be started again when needed. The specific steps or instructions for starting execution or stopping execution are determined by the processor and are not limited to specific aspects.

[0057] In some exemplary embodiments, the computing power margin is a computing power margin ratio, and accordingly, the first and second set thresholds are both ratio thresholds. Alternatively, other parameters are used to indicate the computing power margin, and are set as the first and second set thresholds accordingly, without limitation to the specific aspects of the exemplary embodiments of this application.

[0058] The larger the processor's computing power margin, the lower the processor's current operating load or intensity; the smaller the processor's computing power margin, the higher the processor's current operating load or intensity. When the processor's computing power margin is large (greater than the first set threshold), it indicates that the current processor has a large load redundancy. At this time, using the processor to execute the set task to increase the processor's heat generation has little impact on the execution of the original basic tasks on the processor. When the processor's computing power margin is not large (less than or equal to the first set threshold), it indicates that the current processor has a certain load redundancy, but not much. In some exemplary embodiments, in order to avoid the adverse impact of the newly added execution of the set task on the execution of the original basic tasks on the processor, the execution of the set task is not started; when the processor's computing power margin is small (less than the second set threshold), it indicates that the current processor's load or intensity is large. In this case, for the set task that has been started, the execution is stopped, so that the processor no longer executes the set task for generating more heat, so as to avoid the execution of the set task affecting the normal and reliable execution of the processor's basic tasks.

[0059] For example, if the first set threshold is 40%, it means that when the computing power margin is greater than 40%, the processor can start executing the set task to perform temperature compensation for the ink screen. For another example, if the second set threshold is 10%, it means that when the computing power margin is less than 10%, the processor needs to stop the set task that has been started, that is, stop the running of the set task to prevent the execution of the set task from affecting the execution of normal business function tasks on the processor.

[0060] Understandably, processors in electronic devices typically have a certain amount of spare computing power, which can be used to handle additional tasks or respond to abnormal situations, thereby improving system stability and reliability. Typically, a processor's spare computing power is calculated by measuring load. For example, if the CPU load rate is less than 100%, it indicates that the CPU still has some spare computing power.

[0061] In some exemplary embodiments, step 110 further includes: according to the ink screen's need to adjust the working temperature, the processor maintains the execution state of the set task.

[0062] In some exemplary embodiments, the ink screen needs to adjust the working temperature including: increasing the temperature, decreasing the temperature, and not adjusting;

[0063] Accordingly, according to the adjustment requirement of the ink screen for the working temperature, the processor starts executing the set task, stops executing the set task, or maintains the execution state of the set task, including:

[0064] When the ink screen needs to adjust the working temperature to increase the temperature, starting to execute the set task;

[0065] When the ink screen needs to adjust the working temperature to cool down, stop executing the set task;

[0066] When the ink screen does not need to adjust the working temperature, the execution state of the set task is maintained.

[0067] In some exemplary embodiments, step 110 includes: based on the ink screen's need to adjust the operating temperature and the computing power margin, the processor starts executing a set task, stops executing the set task, or maintains the execution state of the set task, including:

[0068] When the adjustment of the working temperature of the ink display needs to be increased and the computing power margin is greater than a first set threshold, the processor starts executing the set task;

[0069] When the ink screen does not need to adjust the working temperature, the set task execution state is maintained;

[0070] When the ink screen needs to adjust the working temperature to cool down, stop executing the set task;

[0071] When the computing power margin is less than a second set threshold, the processor stops executing the set task;

[0072] The first set threshold is greater than the second set threshold.

[0073] In some exemplary embodiments, the adjustment of the working temperature of the ink screen needs to include: a temperature adjustment amplitude;

[0074] If the temperature adjustment range is greater than 0, it indicates that the operating temperature needs to be increased. If the temperature adjustment range is equal to 0, it indicates that the current operating temperature needs to be maintained, that is, the operating temperature does not need to be adjusted. If the temperature adjustment range is less than 0, it indicates that the current operating temperature needs to be lowered.

[0075] In some exemplary embodiments, the temperature adjustment amplitude is determined according to a difference between a set target temperature range and a current temperature.

[0076] In some exemplary embodiments, the processor starts or stops executing a set task according to the need for the ink screen to adjust the operating temperature, including one or more of the following methods:

[0077] Mode 1: When the ink display needs to adjust the operating temperature to increase the temperature, the processor determines the execution parameters of the set task based on the temperature adjustment range, and starts executing the set task according to the execution parameters; wherein the execution parameters are used to control the amount of heat generated by the processor when executing the set task;

[0078] Mode 2: When the ink display needs to adjust the operating temperature to increase the temperature, the processor selects one of the preset tasks as the set task according to the temperature adjustment range and executes the selected task; wherein different preset tasks generate different levels of heat when executed by the processor;

[0079] Method 3: When the ink screen needs to adjust the working temperature to increase the temperature, the processor selects at least one as the set task from multiple preset tasks according to the temperature adjustment range and executes it; wherein, the larger the temperature adjustment range, the more set tasks are selected.

[0080] In some exemplary embodiments, in method 1, the setting task includes a temperature adjustment amplitude, and the greater the corresponding determined execution parameter, the more heat is generated when the processor is used to execute the setting task. It can be understood that the temperature adjustment amplitude is greater than 0. The greater the adjustment amplitude, the more the temperature needs to be increased, and more heat is required, and the corresponding execution parameter 1 is determined. The smaller the adjustment amplitude, the less the temperature needs to be increased, and less heat is required, and the corresponding execution parameter 2 is determined. The heat generated by the processor when the execution of the setting task is started according to execution parameter 1 is greater than the heat generated by the processor when the execution of the setting task is started according to execution parameter 2. For example, the setting task is an encryption algorithm task, and the execution parameter is the key length of the encryption algorithm. The greater the adjustment amplitude, the longer the key length. Correspondingly, the longer the key, the greater the computational intensity of the processor when executing the encryption algorithm task, and the greater the heat generated by the processor.

[0081] Examples of setting tasks and executing parameters are not listed here one by one.

[0082] In some exemplary embodiments, in method 2, a larger temperature adjustment amplitude corresponds to selecting a task with a higher heat level from a plurality of preset tasks. It can be understood that if the temperature adjustment amplitude is greater than 0, the larger the adjustment amplitude, the more the temperature needs to be raised, and the more heat is needed, then the task with heat level 1 is selected; if the adjustment amplitude is smaller, the smaller the temperature needs to be raised, and the less heat is needed, then the task with heat level 2 is selected. The heat generated by the processor executing the task with heat level 1 is greater than the heat generated by the processor executing the task with heat level 2. For example, three tasks 1, 2, and 3 are preset, and their heat levels are 1, 2, and 3, respectively, indicating that the heat generated during execution is from high to low. When the temperature adjustment amplitude is greater than 3 degrees, task 1 is selected as the set task and executed. When the temperature adjustment amplitude is greater than 1 degree and less than or equal to 3 degrees, task 2 is selected as the set task and executed. When the temperature adjustment amplitude is greater than 0 degrees and less than or equal to 1 degree, task 3 is selected as the set task and executed. More examples are not listed here one by one.

[0083] In some exemplary embodiments, in method 3, a larger temperature adjustment amplitude corresponds to selecting a task with a higher heat generation level from a plurality of preset tasks. It will be understood that if the temperature adjustment amplitude is greater than 0, a larger adjustment amplitude indicates a greater temperature increase and a greater heat requirement, and thus x tasks are selected for execution. A smaller adjustment amplitude indicates a smaller temperature increase and a lesser heat requirement, and thus y tasks are selected for execution, where x is greater than y. The heat generated by executing x tasks is greater than the heat generated by executing y tasks. For example, if three tasks 1, 2, and 3 are preset, and the temperature adjustment amplitude is greater than 3 degrees, tasks 1, 2, and 3 are selected as the set tasks and executed. If the temperature adjustment amplitude is greater than 1 degree but less than or equal to 3 degrees, two tasks (1, 2 or 2, 3 or 1, 3) are selected as the set tasks and executed. If the temperature adjustment amplitude is greater than 0 degrees but less than or equal to 1 degree, one task (1, 2, or 3) is selected as the set task and executed. Further examples are not listed here. It will be understood that when multiple tasks are selected, they are initiated and executed in parallel.

[0084] In some exemplary embodiments, the processor starting or stopping execution of a set task according to the need for the ink screen to adjust the operating temperature further includes:

[0085] Mode 4: When the ink screen needs to adjust the working temperature to cool down, the processor stops executing the set task.

[0086] In some exemplary embodiments, the fourth method includes:

[0087] When the ink screen needs to adjust the working temperature to cool down and the setting task has been started, the processor stops executing the setting task.

[0088] In some exemplary embodiments, the processor starting or stopping execution of a set task according to the need for the ink screen to adjust the operating temperature further includes:

[0089] Mode 5: When the ink screen does not need to adjust the working temperature, the processor maintains the execution state of the set task, that is, does not change the execution state of the set task.

[0090] The processor maintains the execution state of the set task, including:

[0091] When the set task has been started, the state of being started is maintained;

[0092] When the set task is not started for execution, the state of not started for execution is maintained.

[0093] It can be understood that the temperature adjustment amplitude is equal to 0, which means that the working temperature of the ink screen is in (has reached) the normal range. There is no need to change the execution status of the set task, and the status of started execution or not started execution can be maintained.

[0094] In the absence of a conflict, the processor may start executing the task, stop executing the task, or maintain the execution state of the task, which may include one or more of the above-mentioned multiple ways.

[0095] In some exemplary embodiments, the adjustment of the working temperature of the ink screen needs to be determined according to the current working temperature of the ink screen and a set first target temperature range.

[0096] The first target temperature range is predetermined based on the model of the e-ink display. In some embodiments, the first target temperature range is a temperature range within which the e-ink display can maintain optimal operating performance; alternatively, the first target temperature range is a temperature range within which the e-ink display can maintain suboptimal operating performance. This range is flexibly determined based on design requirements and is not limited to a specific aspect.

[0097] In some exemplary embodiments, the adjustment of the operating temperature of the ink screen needs to be determined according to the current operating temperature of the processor and a set second target temperature range.

[0098] Among them, the set second target temperature range is predetermined according to the model of the processor. In some embodiments, the set second target temperature range is the temperature range in which the processor is normally operating; or, the set second target temperature range is the temperature range in which the processor is operating in the optimal state. It is flexibly determined according to design needs and is not limited to specific aspects. It can be understood that based on the close connection between the processor and the ink screen using a heat dissipation medium, the current operating temperature of the processor can be used to indirectly indicate the current operating temperature of the ink screen, and the ink screen can determine the need to adjust the operating temperature based on the current operating temperature of the processor and the set second target temperature range.

[0099] In some exemplary embodiments, the adjustment of the working temperature of the ink screen needs to be determined according to the current working temperature of the electronic device and a set third target temperature range.

[0100] Among them, the set third target temperature range is predetermined according to the electrical characteristics of the electronic device. In some embodiments, the set third target temperature range is the temperature range in which the electronic device is operating normally; or, the set third target temperature range is the temperature range in which the electronic device is operating in the optimal state. It is flexibly determined according to design needs and is not limited to specific aspects. It can be understood that the ink screen is included in the electronic device. As a whole device, the current operating temperature of the electronic device can be used to indirectly indicate the current operating temperature of the ink screen, and the ink screen needs to adjust the operating temperature based on the current operating temperature of the electronic device and the set third target temperature range.

[0101] The first target temperature range, the second target temperature range and the third target temperature range are set independently.

[0102] In some exemplary embodiments, the adjustment of the working temperature of the ink screen includes: increasing the temperature, decreasing the temperature, or not adjusting the temperature.

[0103] In some exemplary embodiments, if the adjustment amplitude of the operating temperature is greater than 0, the corresponding adjustment needs to be heating; if the adjustment amplitude of the operating temperature is equal to 0, the corresponding adjustment needs to be no adjustment, which can also be called the current temperature is normal, and there is no need to adjust the processor heat by starting or stopping the execution of the set task; if the adjustment amplitude of the operating temperature is less than 0, the corresponding adjustment needs to be cooling.

[0104] In some exemplary embodiments, step 110 further includes:

[0105] It should be noted that the adjustment in the embodiment of the present application is required to determine whether to start or stop the execution of the set task or maintain the existing execution state, and heating, cooling or no adjustment represents the adjustment target. Generally speaking, while maintaining the same basic task running status, the heat generation of the processor will increase after additionally starting the execution of the set task; after stopping the execution of the set task, the heat generation of the processor will decrease; keeping the existing execution state unchanged will keep the heat generation stable. It can be understood that the specific value of the increase or decrease in heat generation is not specifically quantified in the actual product use and operation process, in a non-laboratory environment; stable heat generation represents a stable state, that is, the heat generation changes slightly within a certain numerical range, and is not a specific quantitative value that remains unchanged.

[0106] For example, the first target temperature range is set to 35-37 degrees, or the first target temperature range is set to 35 degrees. More examples are not listed here one by one.

[0107] For example, when the first target temperature range is set to 35-37 degrees and the current temperature of the ink screen is 35-37 degrees, the adjustment range is determined to be 0; when the current temperature of the ink screen is 34 degrees, the adjustment range is determined to be 35-34=1; when the current temperature of the ink screen is 38 degrees, the adjustment range is determined to be 37-38=-1; more examples are not listed here one by one.

[0108] In some exemplary embodiments, the current operating temperature of the ink screen, the current operating temperature of the processor and the current operating temperature of the electronic device are obtained using temperature sensors. The temperature obtained by the temperature sensor set on the ink screen is recorded as the current operating temperature of the ink screen, the temperature obtained by the temperature sensor set on the processor is recorded as the current operating temperature of the processor, and the temperature obtained by the temperature sensor set at a position on the electronic device that can represent its average temperature is recorded as the current operating temperature of the electronic device.

[0109] In some exemplary embodiments, the ink screen operating temperature control triggering event includes any of the following events:

[0110] The periodic control interval has expired;

[0111] The current operating temperature of the ink display is lower than a first alarm temperature threshold;

[0112] The current operating temperature of the ink display is higher than a second alarm temperature threshold;

[0113] The current operating temperature of the processor is lower than a third warning temperature threshold;

[0114] The current operating temperature of the processor is higher than a fourth warning temperature threshold;

[0115] The current operating temperature of the electronic device is lower than a fifth alarm temperature threshold;

[0152] In some exemplary embodiments, the electronic device and the sandwich structure are as shown in FIG. 7 .

[0153] In some exemplary embodiments, the electronic device further includes a temperature sensor.

[0154] In some exemplary embodiments, the temperature sensor is configured to obtain a current operating temperature of the ink screen; wherein the adjustment of the operating temperature by the ink screen needs to be determined according to the current operating temperature of the ink screen and a set first target temperature range;

[0155] or,

[0157] or,

[0158] The temperature sensor is configured to obtain the current operating temperature of the electronic device; wherein, the adjustment of the operating temperature by the ink screen needs to be determined according to the current operating temperature of the electronic device and a set third target temperature range.

[0159] For example, as shown in FIG8 , the temperature sensor is provided on the lower surface of the ink screen to obtain the current operating temperature of the ink screen.

[0160] In some exemplary embodiments, the processor is disposed on a main control board.

[0168] When the ink screen needs to adjust the operating temperature to a lower temperature, the processor stops executing the set task;

[0169] The temperature adjustment range is determined according to the difference between the set target temperature range and the current temperature.

[0170] An embodiment of the present application further provides an electronic device, as shown in FIG9 , comprising: an upper cover assembly 1, a heat dissipation medium 2, a main control board 3, a power board 4, and a back cover 5.

[0171] It can be understood that most of the heat generated during the operation of the MCU is transferred to the water-ink screen through the heat dissipation medium 2, and this process maintains a stable and appropriate working environment temperature for the water-ink screen. When the ambient temperature is low and the heat generated by the basic business or control function tasks run by the MCU cannot maintain the working temperature of the water-ink screen, the current temperature obtained by the temperature sensor is notified to the MCU. The MCU determines the need for the water-ink screen to adjust the working temperature based on the current temperature and the set target temperature range, and further determines whether to start executing the additional heating task of the standby processor to increase the heating power (heat generation) of the MCU, thereby increasing the working temperature of the water-ink screen.

Instead, it utilizes the redundant computing power of the processor in the electronic device and the characteristics of generating more operating heat with a higher operating load or intensity. According to the need for temperature increase due to temperature adjustment, the processor starts executing a set task specifically for heat compensation, or, according to the need for temperature reduction due to temperature adjustment, the processor stops executing the started set task, or, according to the need for heat preservation, the processor maintains the execution state of the set task. This avoids the increase in hardware design complexity caused by the addition of new hardware, the increase in equipment cost caused by the addition of new hardware, and the increase in equipment volume that may be caused by the addition of new hardware.

[0174] According to the temperature control solution provided in the embodiment of the present application, the operating temperature of the e-ink screen is controlled without adding temperature compensation hardware. The relationship between the heat generated by the processor during operation of the electronic device and the processor operating load or intensity is utilized. When necessary, the processor initiates the execution of a set task for performing temperature compensation for the e-ink screen (processor additional heating task).
