Description

Technical Field

[0001] The present disclosure relates to the field of automatic control technology, and in particular to a method and device for controlling screen temperature, a readable storage medium, and a vehicle-mounted system. Background Art

[0002] As the interactive experience of in-vehicle multimedia systems becomes increasingly rich, the display screen, as a core interactive terminal, not only undertakes traditional functions such as audio and video entertainment and navigation information display, but has also gradually expanded to include multiple uses such as cabin comfort control, driver assistance information presentation, and personalized scene linkage. Especially in the context of the rapid development of smart cockpits, passengers' requirements for interactive interface responsiveness, touch comfort, and environmental adaptability are constantly increasing.

[0003] However, most current temperature control methods for in-car displays still rely on constant temperature control or simple responses based on external ambient temperature changes. These methods lack the integrated perception and deep understanding of multimodal information within the vehicle. This inability to effectively and dynamically adjust the screen temperature results in poor touch sensitivity, impacting the user experience. Summary of the Invention

[0004] In view of the above problems, the present disclosure provides a screen temperature control method, device, readable storage medium, and vehicle-mounted system that overcome or at least partially resolve the current inability to effectively and dynamically adjust the screen temperature. The technical solutions are as follows:

[0005] A method for controlling screen temperature, the method comprising:

[0006] When playing multimedia content on the first screen, obtaining playback information; the playback information includes the media resource type of the multimedia content;

[0007] Obtaining a screen temperature of a second screen; the first screen and the second screen are different screens in a multi-screen system, and a setting position of the second screen is adapted to a position of an arm when the user is in a target posture;

[0008] When the screen temperature is within a preset temperature range, obtaining a target temperature corresponding to the media resource type;

[0009] The screen temperature of the second screen is adjusted to the target temperature.

[0010] This allows the user's arm to control the temperature of the second screen, which is in contact with the user's arm, by controlling the content playing on the first screen. This allows the user's tactile experience to be coordinated with the visual content, thereby enhancing the user's interactive experience. Furthermore, the screen temperature is adjusted only when it is within a preset range, preventing adjustments when the screen temperature is unsafe and ensuring the safety of screen temperature adjustment.

[0011] Optionally, the playback information further includes at least one of a playback duration and a remaining playback duration; and the method further includes:

[0012] When the played time is greater than a first time threshold, and / or the remaining time is greater than a second time threshold, the screen temperature of the second screen is acquired.

[0013] In this way, the screen temperature of the second screen is obtained only when the played time exceeds the first time threshold, or the remaining time is greater than the second time threshold, thereby avoiding energy waste caused by frequent temperature adjustments in a short period of time and ensuring the stability and energy saving of screen temperature adjustment. Alternatively, when the played time exceeds the first time threshold, it is further determined whether the remaining time is greater than the second time threshold, that is, the screen temperature of the second screen is obtained only when the played time exceeds the first time threshold and the remaining time is greater than the second time threshold. A more refined screen temperature control logic is implemented, that is, the acquisition of the second screen temperature or temperature linkage is triggered only when the multimedia content has been played for a sufficient period of time and there is still a long remaining playback time, thereby avoiding meaningless temperature control operations when the playback is about to end, thereby reducing unnecessary energy consumption and further ensuring the rationality of the temperature control behavior.

[0014] Optionally, adjusting the screen temperature of the second screen to the target temperature includes:

[0015] The display brightness of the second screen is adjusted to adjust the screen temperature of the second screen to the target temperature.

[0016] In this way, by adjusting the display brightness of the second screen to indirectly adjust its screen temperature, intelligent screen temperature control can be achieved without adding a separate heating or cooling module. This ensures that the screen content played and the screen temperature adjustment are linked, thereby improving the user's tactile experience while effectively reducing the system's hardware complexity.

[0017] Optionally, adjusting the display brightness of the second screen to adjust the screen temperature of the second screen to the target temperature includes:

[0018] Obtaining a driving factor; the driving factor includes at least one of a temperature difference and a remaining time; the temperature difference is the temperature difference between the screen temperature and the target temperature, and the remaining time is the remaining playback time of the multimedia content;

[0019] determining an adjustment rate of the screen temperature according to the driving factor;

[0020] The display brightness of the second screen is adjusted to control the second screen to adjust the screen temperature according to the adjustment rate until the screen temperature reaches the target temperature.

[0021] In this way, driving factors including temperature difference or remaining time are obtained, and the adjustment rate of the screen temperature is determined accordingly, so that the brightness adjustment can push the screen temperature towards the target temperature at the most appropriate speed while ensuring the smooth visual experience of the user as much as possible, thereby achieving fast and smooth adjustment of the screen temperature, taking into account both adjustment efficiency and viewing comfort.

[0022] Optionally, determining the adjustment rate of the screen temperature according to the driving factor includes:

[0023] Determining an adjustment rate of the screen temperature based on the temperature difference according to a first mapping relationship; the first mapping relationship is used to represent a mapping relationship between the temperature difference and the adjustment rate;

[0024] or,

[0025] determining an adjustment duration according to the remaining duration, and determining an adjustment rate of the screen temperature according to a second mapping relationship; wherein the second mapping relationship is used to represent a mapping relationship between the adjustment duration and the adjustment rate;

[0026] or,

[0027] The adjustment duration is determined according to the remaining duration, and the adjustment rate of the screen temperature is determined according to the adjustment duration, the temperature difference and a third mapping relationship; the third mapping relationship is used to characterize the mapping relationship between the adjustment duration and the temperature difference and the adjustment rate.

[0028] In this way, if the screen temperature adjustment rate is not controlled, if the rate is too fast, the screen brightness and temperature will fluctuate significantly, potentially damaging the screen hardware and creating an abrupt visual experience that affects the user's perception. Conversely, if the rate is too slow, the media content may end before the screen temperature reaches the target temperature, preventing the user from promptly experiencing the improved tactile experience brought about by temperature control, affecting the integrity of the experience. Therefore, determining the screen temperature adjustment rate based on a mapping relationship between temperature difference, remaining time, and their combination not only protects the screen hardware and visual experience, but also ensures that the screen temperature adjustment is completed within a reasonable time, thereby improving the overall intelligence of the system linkage and user satisfaction.

[0029] Optionally, after adjusting the screen temperature of the second screen to the target temperature, the method further includes:

[0030] When it is determined to stop playing the multimedia content, the screen temperature is controlled to return to a preset temperature value.

[0031] In this way, based on the screen temperature control associated with the playback content, the temperature can be intelligently restored to the preset value when playback stops, which can prevent the screen from being in a non-ideal temperature state for a long time and reduce hardware damage caused by overheating or overcooling.

[0032] Optionally, the multi-screen system is a vehicle system, the first screen is a ceiling screen, and the second screen is an armrest screen located in the rear row of the vehicle.

[0033] This system integrates the multimedia content displayed on the ceiling-mounted display with the temperature of the armrest display. The ceiling-mounted display displays rich multimedia content, while the armrest display intelligently adjusts the temperature and interactive feedback based on the content, significantly enhancing the comfort and immersion of rear passengers. This optimizes the overall interactive environment of the vehicle system, improving its functionality and user experience, and meeting the needs of multiple scenarios and users.

[0037] The acquisition module is further configured to acquire a target temperature corresponding to the media resource type when the screen temperature is within a preset temperature range;

[0038] An adjustment module is used to adjust the screen temperature of the second screen to the target temperature.

[0039] Optionally, the playback information further includes at least one of a playback duration and a remaining duration;

[0040] The acquisition module is further configured to acquire the screen temperature of the second screen when the played duration is greater than a first duration threshold and / or the remaining duration is greater than a second duration threshold.

[0041] Optionally, the adjustment module is specifically used to: adjust the display brightness of the second screen to adjust the screen temperature of the second screen to the target temperature.

[0042] Optional, adjustment module, specifically used for:

[0043] Obtaining a driving factor; the driving factor includes at least one of a temperature difference and a remaining time; the temperature difference is the temperature difference between the screen temperature and the target temperature, and the remaining time is the remaining playback time of the multimedia content;

[0044] determining an adjustment rate of the screen temperature according to the driving factor;

[0045] The display brightness of the second screen is adjusted to control the second screen to adjust the screen temperature according to the adjustment rate until the screen temperature reaches the target temperature.

[0046] Optional, adjustment module, specifically used for:

[0047] Determining an adjustment rate of the screen temperature based on the temperature difference according to a first mapping relationship; the first mapping relationship is used to represent a mapping relationship between the temperature difference and the adjustment rate;

[0048] or,

[0049] determining an adjustment duration according to the remaining duration, and determining an adjustment rate of the screen temperature according to a second mapping relationship; wherein the second mapping relationship is used to represent a mapping relationship between the adjustment duration and the adjustment rate;

[0050] or,

[0051] The adjustment duration is determined according to the remaining duration, and the adjustment rate of the screen temperature is determined according to the adjustment duration, the temperature difference and a third mapping relationship; the third mapping relationship is used to characterize the mapping relationship between the adjustment duration and the temperature difference and the adjustment rate.

[0052] Optionally, the device for controlling the screen temperature further includes a determination module;

[0053] The determination module is configured to, after adjusting the screen temperature of the second screen to the target temperature and determining to stop playing the multimedia content, control the screen temperature to return to a preset temperature value.

[0054] Optionally, the multi-screen system is a vehicle system, the first screen is a ceiling screen, and the second screen is an armrest screen located in the rear row of the vehicle.

[0055] A vehicle-mounted system includes a memory and a processor, wherein the memory stores executable program code, and the processor is used to call and execute the executable program code to perform any optional screen temperature control method as described above.

[0056] A vehicle comprises the above-mentioned vehicle-mounted system.

The first screen and the second screen are different screens in a multi-screen system, and the setting position of the second screen is adapted to the position of the user's arm when the user is in the target posture. Finally, when the screen temperature is within a preset temperature range, the target temperature corresponding to the media resource type is obtained, and the screen temperature of the second screen is adjusted to the target temperature. In this way, the temperature of the second screen that the user's arm contacts can be adjusted by linking the playback content of the first screen, so as to achieve coordination between vision and touch and enhance the interactive experience. At the same time, the screen temperature is only adjusted when it is within the preset temperature range, taking into account the safety of the adjustment.

[0073] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0074] With the development of smart cockpit technology, in-vehicle screens have gradually evolved from single information display devices to comprehensive terminals that integrate multimedia playback, intelligent interaction, and environmental perception. In some models, in order to enhance the passenger experience, touch-sensitive armrest screens or entertainment screens are installed in the rear area of ​​the vehicle, where users can watch videos, listen to music, or perform other interactive operations. However, in related technologies, when controlling the temperature of these screens, in-vehicle systems often adopt fixed strategies or simple ambient temperature response mechanisms, lacking the fusion perception and deep understanding of multimodal information in the vehicle. This results in a lack of timing, relevance, and personalization in the adjustment of screen temperature, and the inability to intelligently adjust the screen temperature according to the current playback context or user interaction status, resulting in the screen's touch temperature being too high or too low, affecting the user's tactile comfort and immersive experience during the interaction process.

[0075] To this end, the present disclosure provides a screen temperature control system, such as Figure 1As shown, the system mainly includes: a controller 200 and multiple display screens 100.

[0076] The display screens 100 provided in the embodiments of the present disclosure are multiple interactive display screens deployed in the same system, used to provide visual output and touch feedback. The controller 200 is used to uniformly manage the operating status of the multiple display screens 100 and can establish a communication connection with each display screen 100 via wired or wireless means to achieve management of each display screen 100.

[0077] In some embodiments, the screen temperature control system can be an in-vehicle environment system (e.g., a vehicle computer system). In this case, the display screen 100 can be multiple display screens installed in the vehicle environment, such as a ceiling screen, an armrest screen, a central control screen, a passenger screen, etc. Different display screens 100 are suitable for different in-vehicle user interaction scenarios. The controller 200 can be a controller in the in-vehicle environment system, for example, the controller 200 is a main controller integrated into the vehicle's main control system, or the controller 200 is a sub-controller used solely for temperature control, used to implement the screen temperature control method of the embodiments of the present disclosure.

[0078] It should be noted that the screen temperature control method provided in the embodiment of the present disclosure can be executed by the controller 200 .

[0079] In addition, the screen temperature control method provided in the embodiment of the present disclosure can be executed by a screen temperature control device, which can be hardware or software. When the screen temperature control device is hardware, it can be various multi-screen systems with the function of controlling the screen temperature, including but not limited to multi-screen car systems, conference systems, smart home systems, etc. When the screen temperature control device is software, it can be installed in the multi-screen systems listed above. It can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0080] Based on the above screen temperature control system, in order to solve the current technical problem of being unable to effectively and dynamically adjust the screen temperature, the present disclosure provides a screen temperature control method, such as Figure 2 As shown, Figure 2 3 is a schematic flow chart of a method for controlling screen temperature provided by an embodiment of the present disclosure, the method comprising the following steps S11-S17.

[0081] S11 , determining whether the first screen is playing multimedia content, and executing S12 when the first screen is playing multimedia content; and ending the process when the first screen is not playing multimedia content.

[0082] Multimedia content refers to digital content that integrates at least one form of information expression from multiple media resources (such as text, images, audio, video, animation, etc.). It can be presented and interacted with via electronic devices and is widely used in various fields, such as entertainment, education, advertising, and communications. Multimedia content can convey information through multiple sensory methods, providing users with a rich, vivid, and immersive experience at the visual, auditory, and even tactile levels. It is an important vehicle for information dissemination and human-computer interaction. The first screen is one screen in a multi-screen system.

[0083] Specifically, the method for determining whether the first screen is playing multimedia content can be to query the status of the multimedia playback module corresponding to the first screen, for example, by querying whether the playback instance bound to the first screen is in the "play" state through the scheduling management service or the screen management middle layer. It can also be determined by detecting the rendering content type of the first screen. For example, when the image rendering engine or middleware detects that the current display content of the first screen is a dynamic multimedia type (such as a video stream, animation stream, etc.), it is determined that the first screen is playing multimedia content. It can also be determined by querying the task type through the system screen task scheduling table. For example, by querying whether the current first screen is assigned a "multimedia playback" type task, it can be determined whether the first screen is playing multimedia content.

[0084] S12. Obtain playback information.

[0085] The playback information includes the media resource type of the multimedia content. The media resource type is used to describe the emotional or thematic attributes of the multimedia content, for example, warmth (such as family, friendship, love, etc.), action, comedy, sadness, inspirational, science fiction, etc.

[0086] Specifically, the method for obtaining the media resource type of multimedia content can be to obtain the media resource type of multimedia content based on the method of metadata tag parsing. Specifically, most multimedia resources carry metadata related to the media resource type when they are produced, distributed or stored, such as content tags, classification fields or emotional tags. Therefore, the media resource type of multimedia content can be obtained by parsing these metadata fields. The method for obtaining the media resource type of multimedia content can also be to automatically identify the media resource type of multimedia content through an artificial intelligence (AI) model. For example, the media resource type of multimedia content can be automatically classified using image recognition, audio emotion recognition or text semantic analysis technology.

[0087] S14. Obtain the screen temperature of the second screen.

[0088] Among them, the first screen and the second screen are different screens in the multi-screen system, and the setting position of the second screen is adapted to the position where the user's arm is placed when the user is in the target posture. The setting position of the second screen is adapted to the position where the user's arm is placed when the user is in the target posture means that the installation or presentation position of the second screen is designed according to the typical posture of the user when using the device (i.e., the target posture), so that when the user is in this posture, the position where the arm is naturally placed just matches the position of the second screen, thereby achieving convenient touch operation or natural interactive experience. For example, when the second screen is an armrest screen in a car system, the second screen is set in the central armrest or side armrest area of ​​the vehicle. When the user sits in a riding posture, his arm can be naturally placed on the armrest, which corresponds to the interactive area of ​​the second screen, so that touch operation can be performed without additional movement or lifting of the arm.

[0089] Specifically, the screen temperature of the second screen can be obtained by using a temperature sensor inside the second screen or on the back panel. Many screens or smart devices integrate temperature sensors in the screen module, so the temperature data provided by the sensor can be read as the screen temperature of the second screen through the device driver or hardware interface. The screen temperature of the second screen can also be obtained by querying the screen temperature of the second screen through the system temperature control management module; or when the driver chip of the second screen supports the temperature sensing function, the temperature sensing value in the driver chip can be read through the control command interface to obtain the screen temperature of the second screen.

[0090] In some embodiments, the multi-screen system is a vehicle computer system, the first screen is a ceiling screen, and the second screen is an armrest screen located in the rear of the vehicle. Specifically, the armrest screen is generally installed in the middle of the rear seats of the vehicle, which is convenient for the rear seat users to set the air conditioning, play audio, turn on and off the ceiling screen, etc., and of course it can also be used as an armrest when the user is resting (that is, the user can put his hand on the armrest screen for support). For example, Figure 3 As shown, the second screen is an armrest screen located between rear seats 1 and 2. In this solution, the vehicle system links the multimedia content of the ceiling screen with the screen temperature of the armrest screen. The ceiling screen displays rich multimedia content, while the armrest screen intelligently adjusts the screen temperature and interactive feedback based on the multimedia content, significantly enhancing the comfort and immersion of rear passengers. This optimizes the overall interactive environment of the vehicle system, improving its functionality and user experience, and meeting the needs of multiple scenarios and users.

[0091] S15. Determine whether the screen temperature is within a preset temperature range. If the screen temperature is within the preset temperature range, execute S16. If the screen temperature is not within the preset temperature range, end.

[0092] The preset temperature range is the safe temperature range for the second screen, determined based on a variety of factors, including the second screen's material properties, structural heat resistance, circuit operating requirements, and user tactile comfort. If the screen temperature is outside the preset temperature range, the process ends, indicating that the screen temperature has exceeded the safe temperature range for the second screen, prioritizing screen safety. Therefore, the linkage between the multimedia content played on the first screen and the screen temperature of the second screen ends, and subsequent steps are discontinued.

[0093] S16. Obtain a target temperature corresponding to the media resource type.

[0094] Specifically, the target temperature corresponding to the media resource type can be obtained by querying the target temperature corresponding to the media resource type based on a preset correspondence relationship. The preset correspondence relationship is pre-determined based on a preset temperature range of the second screen and the tactile perception characteristics corresponding to each media resource type; the preset correspondence relationship includes mapping relationships between multiple media resource types and target temperatures.

[0095] S17. Adjust the screen temperature of the second screen to the target temperature.

[0096] Specifically, the screen temperature of the second screen can be adjusted to the target temperature by using a temperature control module in the multi-screen system (such as a heating film, a thermoelectric cooling sheet, an intelligent heat dissipation component, etc.); or it can be directly adjusted by the temperature control unit built into the second screen, that is, if the second screen has independent temperature control capabilities (such as a built-in temperature control chip or a driving circuit), the screen temperature of the second screen can be directly adjusted to the target temperature by using the temperature control unit built into the second screen; or the screen temperature of the second screen can be adjusted by adjusting the screen backlight or power supply parameters through the temperature control drive layer, that is, adjusting parameters such as the backlight brightness, current voltage, and pulse width modulation (PWM) signal to indirectly control the temperature of the screen, thereby adjusting the screen temperature of the second screen to the target temperature.

[0097] In the above solution, first, when multimedia content is played on the first screen, playback information is obtained. This playback information includes the elapsed playback duration of the multimedia content and the media resource type. Then, when the elapsed playback duration exceeds a first duration threshold, the screen temperature of the second screen is obtained. The first and second screens are different screens in a multi-screen system, and the second screen is positioned to match the position of the user's arm when in a target posture. Finally, when the screen temperature is within a preset temperature range, a target temperature corresponding to the media resource type is obtained, and the screen temperature of the second screen is adjusted to the target temperature. This, on the one hand, controls the screen temperature of the second screen in contact with the user's arm in conjunction with the content played on the first screen, aligning the user's tactile experience with the visual content and enhancing the user's interactive experience. On the other hand, the screen temperature is adjusted only when the elapsed playback duration of the multimedia content exceeds the first duration threshold and the screen temperature is within the preset temperature range. This avoids energy waste caused by frequent temperature adjustments in a short period of time and prevents adjustments when the screen temperature is within an unsafe range, thereby ensuring the stability, energy efficiency, and safety of screen temperature adjustment.

[0098] In some embodiments, the playback information also includes the playback time, such as Figure 4B As shown, the method for controlling the screen temperature further includes the following steps S13-S14, wherein the explanations of the terms and steps that are the same as or corresponding to the above embodiments are not repeated here.

[0099] S13: Determine whether the broadcast duration is greater than a first duration threshold, and if so, execute S14; if so, terminate.

[0100] The first duration threshold is a preset duration, for example, a default value, or a value set by relevant personnel according to actual conditions. For another example, the first duration threshold is 5 minutes. The process ends when the played duration is less than or equal to the first duration threshold. The played duration is less than or equal to the first duration threshold, which means that the playback duration of the multimedia content is short. At this time, the linkage is less meaningful. Therefore, the linkage between the multimedia content played on the first screen and the screen temperature of the second screen is ended, that is, the subsequent steps are no longer executed.

[0101] Specifically, the method for obtaining the elapsed playback duration of multimedia content can be to obtain the elapsed playback duration of the multimedia content through the application programming interface (API) of the multimedia player in the multi-screen system. Alternatively, the method can be to obtain the elapsed playback duration of the multimedia content by monitoring the player playback event and recording the timestamp. Alternatively, the method can be to obtain the elapsed playback duration of the multimedia content by querying the playback information in the media control service of the multi-screen system.

[0102] S14. Obtain the screen temperature of the second screen.

[0103] In the above solution, the screen temperature of the second screen is obtained only when the broadcast duration exceeds the first duration threshold, avoiding energy waste that may be caused by frequent temperature adjustment in a short period of time, and ensuring the stability and energy saving of screen temperature adjustment.

[0104] In some embodiments, the playback information also includes the remaining time, such as Figure 4C As shown, the method for controlling the screen temperature further includes the following steps S131-S14, wherein the explanations of the terms and steps that are the same as or corresponding to the above embodiments are not repeated here.

[0105] S131. Determine whether the remaining time is greater than a second time threshold; if the remaining time is greater than the second time threshold, execute S14; if the remaining time is less than or equal to the second time threshold, end.

[0106] The second duration threshold is a preset duration, for example, a default value, or a value set by relevant personnel according to actual conditions. The remaining duration is the time length from the current playback position of the multimedia content to the end of the content.

[0107] Specifically, since the corresponding remaining duration cannot be obtained for some special multimedia content (such as real-time streaming media, multimedia content that is not fully buffered, etc.), the remaining duration is only judged when the remaining duration of the multimedia content can be obtained to ensure the rationality of the temperature control behavior.

[0108] In addition, ending when the remaining time is less than or equal to the second time threshold means terminating the linkage between the multimedia content played on the first screen and the screen temperature of the second screen, that is, ending the linkage between the multimedia content played on the first screen and the screen temperature of the second screen, that is, no longer continuing to execute subsequent steps.

[0109] S14. Obtain the screen temperature of the second screen.

[0110] In the above solution, the screen temperature of the second screen is obtained only when the remaining time is greater than the second time threshold, avoiding energy waste that may be caused by frequent temperature adjustment in a short period of time, and ensuring the stability and energy saving of screen temperature adjustment.

[0111] In some embodiments, the playback information also includes the playback time and the remaining time, such as Figure 4A As shown, the method for controlling the screen temperature further includes the following steps S13-S14, wherein the explanations of the terms and steps that are the same as or corresponding to the above embodiments are not repeated here.

[0112] S13: Determine whether the broadcast duration is greater than a first duration threshold, and if so, execute S131; if so, terminate.

[0113] S131. Determine whether the remaining time is greater than a second time threshold; if the remaining time is greater than the second time threshold, execute S14; if the remaining time is less than or equal to the second time threshold, end.

[0114] S14. Obtain the screen temperature of the second screen.

[0115] In the above scheme, when the playback time exceeds the first time threshold, it is further determined whether the remaining time is greater than the second time threshold, thereby realizing a more refined screen temperature control logic. That is, the acquisition of the second screen temperature or temperature linkage is triggered only when the multimedia content has been played for a sufficient length of time and there is still a long remaining playback time, thereby avoiding meaningless temperature control operations when the playback is about to end, thereby reducing unnecessary energy consumption and further ensuring the rationality of the temperature control behavior.

[0116] In some embodiments, the screen temperature of the second screen may be adjusted to the target temperature by adjusting the display brightness of the second screen to adjust the screen temperature of the second screen to the target temperature.

[0117] Specifically, screen temperature is directly proportional to changes in screen brightness. That is, with other influencing factors remaining constant, higher screen brightness results in greater luminous intensity, generating more heat and causing the screen temperature to rise. Conversely, lower screen brightness results in less heat generation and a corresponding decrease in screen temperature. Therefore, this characteristic can be used to adjust the screen temperature of the second screen to the target temperature.

[0118] In this solution, the screen temperature is indirectly adjusted by adjusting the brightness of the second screen, eliminating the need for a separate heating or cooling module. This allows for intelligent control of the screen temperature. This ensures that the screen content is linked to the screen temperature, enhancing the user experience while also effectively reducing the system's hardware complexity.

[0119] In some embodiments, as Figure 5 As shown, adjusting the display brightness of the second screen to adjust the screen temperature of the second screen to the target temperature may include the following steps S131-S173.

[0120] S171. Obtain driving factors.

[0121] The driving factor includes at least one of a temperature difference and a remaining time; the temperature difference is the temperature difference between the screen temperature and the target temperature, and the remaining time is the remaining playback time of the multimedia content.

[0122] Specifically, the temperature difference can be obtained by directly determining the difference between the target temperature and the screen temperature as the temperature difference. A positive temperature difference indicates that the screen temperature is lower than the target temperature and the screen temperature needs to be increased. A negative temperature difference indicates that the current screen temperature is higher than the target temperature and the screen temperature needs to be lowered. When the temperature difference is zero or within the allowable temperature deviation range, no temperature adjustment is required.

[0123] The remaining duration of multimedia content can be obtained by first obtaining the total playback duration and the elapsed playback duration of the multimedia content, and then calculating the remaining duration of the multimedia content based on the total playback duration and the elapsed playback duration. Alternatively, if the player or media service provides a method or property for directly obtaining the remaining duration, the remaining duration of the multimedia content can be obtained by directly calling the remaining duration interface provided by the player or media engine.

[0124] It should be noted that for some multimedia contents with special remaining duration that cannot be obtained (such as real-time streaming media, multimedia contents that are not fully buffered, etc.), the corresponding driving factors only include temperature difference.

[0125] S172. Determine the adjustment rate of the screen temperature according to the driving factor.

[0126] Specifically, when the driving factor includes a temperature difference, the screen temperature adjustment rate can be determined based on the driving factor by dynamically calculating the screen temperature adjustment rate based on the magnitude of the temperature difference. For example, when the temperature difference is large, the temperature is raised or lowered at a higher rate; as the temperature difference gradually decreases, the adjustment rate is reduced accordingly to prevent temperature overshoot or large temperature fluctuations. The adjustment rate can be calculated using a linear relationship, a piecewise function, or the proportional term in a proportional-integral-derivative (PID) control algorithm to achieve real-time linkage between the temperature adjustment rate and the driving factor, thereby driving the brightness adjustment to work on demand and ultimately achieving a smooth transition of the screen temperature.

[0127] When the driving factor includes the remaining duration, the method for determining the adjustment rate of the screen temperature based on the driving factor can be to dynamically set the adjustment rate of the screen temperature based on the remaining duration of the current multimedia content. For example, when the remaining duration is long, a lower adjustment rate can be set so that the screen temperature gradually transitions to the target temperature during content playback; when the remaining duration is short, in order to complete the temperature adjustment as quickly as possible, the adjustment rate can be increased to speed up the temperature control response speed. Among them, time-aware control of the temperature adjustment rate can be achieved by setting a functional mapping relationship between the remaining duration and the adjustment rate, or by presetting multiple remaining duration intervals and assigning corresponding rate parameters to each interval.

[0128] When the driving factors include temperature difference and remaining time, the method for determining the adjustment rate of the screen temperature based on the driving factors can be: when the temperature difference is large and the remaining time is sufficient, a higher adjustment rate is used to quickly reach the target temperature; when the temperature difference is large but the remaining time is short, the adjustment rate should also be increased to ensure that the adjustment is completed within a limited time; when the temperature difference is small and the remaining time is sufficient, the adjustment rate can be reduced to achieve smooth adjustment; and when the temperature difference is small and the remaining time is short, the adjustment rate is maintained or fine-tuned to avoid unnecessary over-adjustment. The adjustment rate can be dynamically calculated through function mapping or control algorithm, for example, using a weight function to combine the temperature difference and the remaining time to control the display brightness, thereby achieving smooth and rhythmic screen temperature adjustment.

[0129] In some embodiments, when the driving factor includes a temperature difference, the method of determining the screen temperature adjustment rate based on the driving factor may also be to determine the screen temperature adjustment rate based on the temperature difference according to a first mapping relationship. The first mapping relationship is used to represent the mapping relationship between the temperature difference and the adjustment rate.

[0130] When the driving factor includes the remaining duration, the screen temperature adjustment rate may be determined based on the driving factor by determining the adjustment duration based on the remaining duration and determining the screen temperature adjustment rate based on a second mapping relationship, wherein the second mapping relationship is used to represent a mapping relationship between the adjustment duration and the adjustment rate.

[0131] When the driving factors include temperature difference and remaining time, the screen temperature adjustment rate can be determined based on the driving factors. Alternatively, the adjustment time can be determined based on the remaining time, and the screen temperature adjustment rate can be determined based on the adjustment time, temperature difference, and a third mapping relationship. The third mapping relationship represents the mapping relationship between the adjustment time, temperature difference, and adjustment rate. In the above scheme, if the screen temperature adjustment rate is not controlled, if the rate is too fast, the screen brightness and temperature will fluctuate significantly, potentially damaging the screen hardware and creating an abrupt visual experience that affects the user experience. Conversely, if the rate is too slow, media content playback may end before the screen temperature reaches the target temperature, preventing the user from promptly experiencing the improved tactile experience brought about by temperature control, affecting the overall user experience. Therefore, determining the screen temperature adjustment rate based on the mapping relationship between temperature difference, remaining time, and their combination protects the screen hardware and visual experience while ensuring that the screen temperature adjustment is completed within a reasonable timeframe, thereby improving the overall intelligence of the system and enhancing user satisfaction.

[0132] S173: Adjust the display brightness of the second screen to control the second screen to adjust the screen temperature according to the adjustment rate until the screen temperature reaches the target temperature.

[0133] Specifically, the display brightness of the second screen is adjusted to control the second screen to adjust the screen temperature according to the adjustment rate until the screen temperature reaches the target temperature. The method can be to dynamically calculate the change amplitude of the display brightness of the second screen according to the adjustment rate, and call the brightness control interface to gradually adjust the display brightness according to the change amplitude, thereby controlling the second screen to adjust the screen temperature according to the adjustment rate until the screen temperature reaches the target temperature. Among them, the specific process can be: first, convert the adjustment rate into the brightness increase or decrease per unit time, and determine the brightness step size (i.e., the change amplitude) for each adjustment; then, by calling the brightness control interface provided by the system or hardware, the current brightness is gradually increased or decreased according to the brightness step size to achieve smooth brightness changes. After each adjustment, wait for a short time interval and collect the latest temperature data, adjust the subsequent brightness step size according to the feedback, ensure that the screen heat generation is consistent with the temperature adjustment rate, thereby achieving precise control and dynamic adjustment of the screen temperature.

[0134] In the above scheme, driving factors including temperature difference or remaining time are obtained, and the adjustment rate of the screen temperature is determined accordingly, so that the brightness adjustment can push the screen temperature towards the target temperature at the most appropriate speed while ensuring the smooth visual experience of the user as much as possible, thereby achieving fast and smooth adjustment of the screen temperature, taking into account both adjustment efficiency and viewing comfort.

[0135] In some embodiments, as Figure 6As shown, after the screen temperature of the second screen is adjusted to the target temperature, the screen temperature control method further includes the following step S18.

[0136] S18. When it is determined to stop playing the multimedia content, control the screen temperature to return to a preset temperature value.

[0137] The preset temperature value may be a pre-set temperature value, or may be the temperature of the second screen before the multimedia content played on the first screen is linked to the screen temperature of the second screen.

[0138] Specifically, the method of controlling the screen temperature to return to the preset temperature value is the same as the temperature adjustment method of adjusting the screen temperature of the second screen to the target temperature in S17, and will not be repeated here.

[0139] In the above solution, based on the screen temperature control associated with the playback content, the temperature is intelligently restored to the preset value when the playback stops, which can prevent the screen from being in a non-ideal temperature state for a long time and reduce hardware damage caused by overheating or overcooling.

[0140] In some embodiments, after adjusting the screen temperature of the second screen to the target temperature, the screen temperature control method further includes: when it is determined that the first screen switches to play new multimedia content, returning to execute S11-S17 to achieve continuous linkage control of the temperature of the second screen until it is determined that the first screen stops playing multimedia content. In the above scheme, by returning and re-executing the control process when the first screen switches to play new multimedia content, the continuous update and dynamic linkage control of the temperature adjustment logic of the second screen are achieved, so that the temperature control strategy can respond in real time according to the changes in the currently played content, ensuring the consistency of the tactile experience and the visual content. In this way, not only the user's interactive continuity and immersion in long-term, multi-segment playback scenarios are improved, but also the problem of temperature control lag or failure caused by changes in playback content is effectively avoided, thereby further improving the intelligence and adaptability of the screen temperature control method.

[0141] In some embodiments, before S17, the screen temperature control method further includes: displaying a prompt message on the second screen, the prompt message including at least the temperature information of the second screen, indicating that the screen temperature linkage function has been enabled. Thus, before performing the temperature adjustment on the second screen, a prompt message is displayed on the second screen, allowing the user to clearly understand that the screen temperature linkage function is currently enabled and to be aware of the temperature status of the second screen. This helps to improve the user's perception and understanding of system behavior and enhance the transparency and trust of human-computer interaction. At the same time, this prompt mechanism can also effectively prevent users from misunderstandings or misoperations due to temperature changes, further improving the user experience and system controllability, and reflecting the humanized design and interactive friendliness of the screen temperature control method.

[0142] In some embodiments, the screen temperature control method further includes: in response to a user-defined screen temperature set on the second screen, adjusting the temperature of the second screen to the defined screen temperature upon determining that the defined screen temperature is within a preset temperature range. This allows users to set a defined screen temperature on the second screen and adjust the temperature after confirming that the temperature is within a preset safety range, thereby increasing the user's ability to proactively control the screen temperature of the second screen, enhancing the personalized experience and meeting the diverse needs of different users for tactile comfort. Furthermore, while ensuring temperature control safety, this mechanism further enhances the flexibility and user satisfaction of the screen temperature control method, demonstrating a good balance between intelligence and user engagement in the temperature control strategy.

[0143] The embodiment of the present disclosure can divide the functional modules of the screen temperature control device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present disclosure is schematic and is only a logical functional division. There may be other division methods in actual implementation.

Finally, when the screen temperature is within the preset temperature range, the target temperature corresponding to the media resource type is obtained, and the screen temperature of the second screen is adjusted to the target temperature. In this way, on the one hand, the playback content in the first screen is linked to control the screen temperature of the second screen that the user's arm contacts, so that the user's tactile experience is coordinated with the visual content, thereby enhancing the user's interactive experience. On the other hand, the screen temperature can be adjusted only when the screen temperature is within the preset temperature range, preventing adjustment when the screen temperature is within an unsafe range, thereby ensuring the safety of screen temperature adjustment.
