Description

Technical Field

[0001] The present application relates to the field of outdoor protection for smart watches, and more specifically, to a method and system for displaying a screen off of a smart watch, and a polarized screen. Background Art

[0002] With the popularization of smart wearable technology, smart watches have become a powerful assistant in people's daily life and sports travel. The screen-off display function greatly improves the convenience of obtaining information. Users can quickly know the time and date and get important notifications in time without turning on the screen.

[0003] However, this originally convenient function encounters severe challenges when users are outdoors in strong light. During outdoor activities such as mountaineering and cycling, strong sunlight shines on the smartwatch screen, causing severe reflection and glare. Even if the screen is in the off state, users find it difficult to see the screen information clearly, resulting in the inability to obtain key information in a timely manner.

[0004] To solve the problem of screen reflection, traditional technologies mostly use the method of increasing screen brightness. However, this method is only applicable when the screen is on. When the smartwatch is in the screen-off state, this method does not work. In addition, if the display brightness is increased directly in the screen-off state, it will not only consume a lot of power and significantly shorten the battery life of the smartwatch, but also in some extreme light environments, it still cannot effectively improve the screen visibility and is difficult to meet the actual needs of users. This shows that in the screen-off display scenario, there is an urgent need for a solution that can both ensure screen visibility in a strong light environment and take into account low power consumption. Summary of the invention

[0005] Based on the problems existing in the prior art, this application provides a method, system and polarized screen for displaying the screen of a smart watch. The specific solution is as follows: In the first part, the present application proposes a method for displaying a smartwatch screen off, comprising: Determine an outdoor area that the user will visit during a preset first time period, and obtain a predicted light intensity of the outdoor area during the first time period; Based on the predicted light intensity, a time period in which the light intensity is in a preset high light interval within the first time period is selected to obtain a strong light period, and when the proportion of the strong light period in the first time period exceeds a preset ratio, a preset polarization screen composed of a multi-layer structure is provided externally to the smart watch; Based on the preset low-light interval, predicted light intensity and strong light period, the polarization screen is configured with initial electric field parameters in the normal mode and excitation electric field parameters that can cause it to enter the polarization mode; According to the screen parameters of the polarized screen in the normal mode and the polarized mode, respectively configure the screen-off display mode of the smart watch to obtain a first screen-off display mode and a second screen-off display mode; In the outdoor area, determine whether to apply the excitation electric field parameters to the polarization screen; if not, operate in normal mode and enable the smart watch to display in the first screen-off display mode; if applied, operate in polarization mode and enable the smart watch to display in the second screen-off display mode.

[0006] In some specific embodiments, whether it is currently suitable to obtain the actual light intensity is analyzed based on the energy consumption data of the smart watch; If appropriate, determining whether to apply the excitation electric field parameters to the polarization screen by comparing the actual illumination intensity with the preset high illumination interval; If not suitable, then the excitation electric field parameters are applied to the polarization screen at least during the strong light period.

[0007] In some specific embodiments, the first screen-off display mode includes: Obtaining actual light intensity and determining whether the actual light intensity is in the high light interval: If not, adjust the screen brightness of the smartwatch according to the actual light intensity; If so, the screen-off display brightness of the smart watch is adjusted to a preset highlight range, or the second screen-off display mode is used for display and the excitation electric field parameters are applied to the polarized screen.

[0008] In some specific embodiments, the multi-layer structure of the polarizing screen has a liquid crystal layer interspersed therebetween; Applying an electric field to the liquid crystal layer according to the excitation electric field parameters changes the arrangement direction of the liquid crystal molecules, so that the polarization screen only allows light with a specific polarization direction to pass through, reducing the reflected light entering the smart watch, allowing the user to observe the screen display content of the smart watch through the polarization screen.

[0009] In some specific embodiments, the multi-layer structure of the polarizing screen has an electrochromic layer interspersed therebetween; An electric field is applied to the electrochromic layer according to the excitation electric field parameters to cause a redox reaction to change the optical properties, thereby absorbing and scattering light in a partial polarization direction, reducing reflected light entering the smart watch, and allowing the user to observe the screen-off display content of the smart watch through the polarized screen.

[0010] In some specific embodiments, the method further includes obtaining a predicted ambient temperature of the outdoor area during a first period of time; Analyze and predict whether the ambient temperature is in an extreme temperature period that exceeds the preset normal temperature range; If so, the extreme temperature period is excluded at least in the strong light period, and the actual ambient temperature is obtained in the outdoor area. When the actual ambient temperature exceeds the normal temperature range, application of the excitation electric field parameters to the polarization screen is stopped.

[0011] In some specific embodiments, a user's viewing posture for the smart watch is predetermined; When the light intensity is in the low light range, the initial electric field parameters are set so that the polarization effect of the polarization screen on light is weakest, and the screen-off display mode of the smart watch is continuously adjusted until the screen-off display content of the smart watch can be clearly seen through the polarization screen in the viewing posture, thereby obtaining a first screen-off display mode.

[0012] In some specific embodiments, the maximum light intensity among the predicted light intensities is found, and when the light intensity is at the maximum light intensity, the electric field parameters of the polarized screen and the screen-off display mode of the smart watch are continuously adjusted until the screen-off display content of the smart watch can be clearly seen through the polarized screen in the viewing posture, and the operating time and operating duration of the screen-off display mode are determined in combination with the strong light period, so as to obtain the excitation electric field parameters and the second screen-off display mode.

[0013] In the second part, the present application proposes a smart watch screen-off display system under extreme temperatures, comprising: A data acquisition unit, used to determine an outdoor area that the user will visit during a preset first time period, and to acquire a predicted light intensity of the outdoor area during the first time period; A polarization configuration unit, configured to select a time period in which the light intensity is in a preset high light interval within the first time period based on the predicted light intensity to obtain a strong light period, and to provide the smart watch with a preset polarization screen composed of a multi-layer structure when the proportion of the strong light period in the first time period exceeds a preset ratio; Based on the preset low-light interval, predicted light intensity and strong light period, the polarization screen is configured with initial electric field parameters in the normal mode and excitation electric field parameters that can cause it to enter the polarization mode; A screen-off configuration unit, configured to respectively configure the screen-off display mode of the smart watch according to the screen parameters of the polarized screen in the normal mode and the polarized mode, so as to obtain a first screen-off display mode and a second screen-off display mode; The implementation unit is used to determine whether to apply the excitation electric field parameters to the polarization screen in the outdoor area; if not, it operates in normal mode and enables the smart watch to display in the first screen-off display mode; if applied, it operates in polarization mode and enables the smart watch to display in the second screen-off display mode.

[0014] In the third part, the present application proposes a polarization screen for implementing the smart watch screen-off display method described in the first part, wherein the polarization screen is detachably arranged above the smart watch screen; The polarizing screen comprises a first transparent electrode layer, a second transparent electrode layer and a polarizing plate layer located between the first transparent electrode layer and the second transparent layer; The first transparent electrode layer and the second transparent layer cooperate with each other to apply an electric field to the polarizer layer; the polarizer layer is used to reduce the passage of light under the action of the electric field.

[0015] Beneficial effects: This application proposes a method, system and polarized screen for displaying the screen off of a smart watch. By applying an electric field to an external polarized screen to filter the reflected light in a specific direction, the reflected light entering the smart watch is reduced, so that the user can clearly observe the display content of the smart watch through the polarized screen even in strong light conditions, reduce glare interference, and significantly improve the visibility of the smart watch in complex lighting environments. The reflected light is filtered by an external polarized screen, and various factors are comprehensively considered to determine whether to apply excitation electric field parameters to the polarized screen, thereby reducing unnecessary energy consumption in low-light scenarios or scenarios where the polarization function is not required. The smart watch can adjust the brightness of the screen off display in real time according to the actual light intensity, and cooperate with the switching of the polarized screen working mode. When the light increases, the screen brightness is increased, and the polarized screen is put into polarization mode in a timely manner; when the light decreases, the brightness is reduced, and the polarized screen is switched back to normal mode. The dynamic display strategy ensures that users can have a clear and comfortable visual experience under various lighting conditions.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] This application proposes a method for displaying the screen off of a smart watch. By predicting the light intensity, the strong light period is identified, and an external polarized screen is provided for the smart watch. The polarized screen is put into polarized mode according to the excitation electric field parameters, and the reflected light in a specific direction is filtered to reduce glare interference. The flow chart of the display method is shown in the attached figure. Figure 1 The principle is shown in the attached Figure 2 The specific plan is as follows: A smart watch screen-off display method, comprising: 101. Determine an outdoor area that the user will visit during a preset first time period, and obtain a predicted light intensity of the outdoor area during the first time period; 102. Based on the predicted light intensity, a period in which the light intensity is in a preset high light interval within the first period is selected to obtain a strong light period, and when the proportion of the strong light period in the first period exceeds a preset ratio, a preset polarization screen composed of a multi-layer structure is provided for the smart watch; based on the preset low light interval, the predicted light intensity and the strong light period, initial electric field parameters in a normal mode and excitation electric field parameters that can cause the polarization screen to enter a polarization mode are configured for the polarization screen; 103. According to the screen parameters of the polarized screen in the normal mode and the polarized mode, respectively configure the screen-off display mode of the smart watch to obtain a first screen-off display mode and a second screen-off display mode; 104. In an outdoor area, determine whether to apply excitation electric field parameters to the polarization screen; if not, operate in normal mode and enable the smart watch to display in the first screen-off display mode; if applied, operate in polarization mode and enable the smart watch to display in the second screen-off display mode.

[0022] This application introduces an external polarized screen and develops a series of targeted designs around it, effectively overcoming the problem of the screen-off display of smart watches in complex outdoor environments. In strong outdoor light environments, the screen-off display content of ordinary smart watches will be difficult to see due to screen reflections. By configuring the smart watch with an external polarized screen, the reflected light can be effectively filtered, visibility can be improved, and users can easily read the screen information even when the screen is off. The polarized screen, combined with the intelligent electric field parameter control mechanism, can turn off the polarization function in low-light or screen-off scenarios where the polarization function is not required to avoid additional power consumption. In strong light screen-off scenarios, turning on the polarization mode at the right time can ensure that the screen content is visible without causing unnecessary power consumption, which is crucial for smart watches with limited battery life.

[0023] Step 101 identifies the outdoor places that the user plans to visit within a specific preset time period. The preset first time period can be a time period of a certain day set by the user, such as 8 am to 10 am, or a time period automatically set by the smartwatch based on the user's daily habits. There are many ways to determine the outdoor area, such as manually inputting the destination by the user, synchronizing the itinerary of the smartwatch with other devices (such as a mobile phone), or inferring based on the user's past travel patterns.

[0024] After determining the outdoor area that the user wants to go to and the corresponding preset first time period, the smart watch needs to obtain the light intensity forecast data of the area during this time period. This is usually achieved by exchanging data with the meteorological service platform on the Internet or a professional light data provider, and combining the geographical location, date and time of the outdoor area to obtain the corresponding light intensity forecast value. Suppose the preset first time period set by the user is from 12 noon to 2 pm on a summer day, and the outdoor area to be visited is a seaside beach. By connecting to the meteorological service platform, the smart watch obtains that the light intensity of the seaside beach during this period may reach more than 10,000 lux due to direct sunlight. If it is in a city park on a cloudy day, the predicted light intensity may be only 2,000 - 3,000 lux during the same period.

[0025] Based on the predicted light intensity of the outdoor area in the preset time period obtained above, the time periods where the light intensity is in the preset high light range are screened out, and these time periods are defined as strong light periods. For example, the preset time period is from 8 to 10 in the morning, and the predicted light intensity shows that the light intensity reaches 9000 lux from 9 to 9:30, which is in the preset high light range (greater than 8000 lux), then 9 to 9:30 is the screened strong light period.

[0026] The proportion of the strong light period in the preset first period is calculated, and the proportion is compared with the preset ratio. The preset ratio is a preset threshold, such as 30%. If the proportion of the strong light period in the first period exceeds the preset ratio, the smart watch is equipped with a preset polarized screen composed of a multi-layer structure. This is because when the proportion of the strong light period is large, it means that most of the time in the preset period is in a strong light environment, and the ordinary screen display may be greatly affected, while the polarized screen can effectively reduce the reflected light and improve the visibility of the screen under strong light.

[0027] The preset low light interval and the preset high light interval are both pre-set light intensity ranges, representing low light and high light conditions, respectively. Exemplarily, 0-1000 lux can be set as the low light interval, within which the smart watch can use lower screen brightness and weaker polarization processing to save power and ensure better display effects; 5000 lux and above are set as the high light interval, and when the light intensity reaches this range, the strong light response mechanism of the smart watch is triggered, such as an external polarized screen or adjusting the screen display parameters to improve the visibility of the screen under strong light. In actual applications, adaptive selection and adjustment can be made according to the screen conditions of the smart watch, different environments, and different weather conditions. Understand the display effects of the smart watch screen under different light intensities, including contrast, brightness, viewing angle, etc. Determine at what light intensity the screen display begins to have obvious reflections, unclear content, and other problems, and at what light intensity the screen can display normally with low power consumption. For example, if the smartwatch screen has severe reflections when the light intensity exceeds 5000 lux, making the screen display difficult to read, then you can set 5000 lux as the lower limit of the high light range. Through actual experiments and tests, observe the display effect and user experience of smartwatches under different light range settings. You can invite different users to participate in the test, collect their feedback on the screen display effect, and adjust the light range settings based on the feedback.

[0028] In this application, the normal mode and polarization mode of the smart watch are two different working states, which differ in screen display effects, power consumption, and applicable scenarios. In normal mode, the smart watch screen works in a conventional way. The liquid crystal molecules are arranged according to the preset electric field state, and images and text are displayed by controlling the polarization direction and transmittance of the liquid crystal molecules to light. In this mode, the color, contrast, and viewing angle of the screen display can meet general usage requirements. It is suitable for daily indoor environments, such as offices and homes where the light intensity is low and stable. In these environments, users can clearly view the time, message notifications, browse simple application interfaces, etc. At the same time, the power consumption of normal mode is relatively low, which helps to extend the battery life of smart watches.

[0029] When a smartwatch enters polarization mode, it is usually achieved through an external polarization screen or by adjusting the polarization characteristics of the screen itself. The polarization screen is composed of a multi-layer structure, in which the polarizer layer filters the light and only allows light polarized in a specific direction to pass through. In a strong light environment, the reflected light is usually chaotic polarized light. The polarization screen can effectively reduce the interference of these reflected lights, making the content displayed on the screen clearer and more visible. For example, when strong external light shines on the screen, the polarization screen will filter out the reflected light that does not match its own polarization direction, and only allow the adjusted light to pass through, thereby improving the contrast and visibility of the screen. The polarization mode is mainly used to cope with strong light environments, such as in high-intensity scenes such as direct sunlight outdoors. In these cases, the ordinary normal mode display is easily affected by strong light reflections, making the screen content difficult to see clearly. The polarization mode can significantly improve the visual effect of the screen under strong light, allowing users to easily read the time, view navigation information or other important data even in dazzling light. However, due to the need for additional polarization processing, this mode may increase power consumption to a certain extent.

[0030] When the smartwatch is in a strong light period and the light intensity exceeds the preset high light interval (such as above 5000 lux), the excitation electric field parameters need to be configured to make the polarized screen enter the polarization mode. The excitation electric field parameters should be determined according to the characteristics of the polarized screen and the requirements of the strong light environment. Generally speaking, a strong electric field needs to be applied to cooperate with the polarizer layer to achieve effective filtering of strong light and display optimization. For example, by adjusting the intensity and direction of the excitation electric field, the polarization direction of the liquid crystal molecules is matched with the polarization direction of the polarizer layer, thereby minimizing the interference of reflected light and improving the visibility of the screen under strong light. Predicting the trend of light intensity changes is also important for the configuration of the excitation electric field parameters in the polarization mode. If the light intensity is predicted to increase during the strong light period, the excitation electric field parameters may need to be increased accordingly to cope with the increasing strong light; conversely, if the light intensity is predicted to decrease, the excitation electric field parameters can be appropriately weakened, but it is still necessary to ensure that the display effect of the polarization mode can be effectively maintained. For example, during mountain climbing, as the sun gradually rises, the light intensity continues to increase. The smart watch needs to gradually adjust the excitation electric field parameters based on the predicted rising trend of light intensity to ensure that the screen remains clearly visible in strong light throughout the entire climbing process.

[0031] In addition, when configuring the excitation electric field parameters, it is also necessary to monitor the display effect of the screen in real time and make adjustments based on feedback. The built-in light sensor or other detection mechanism of the smart watch can be used to obtain information such as the reflected light intensity and contrast of the screen in real time. If it is found that the screen display still has reflections or poor visibility, it means that the excitation electric field parameters may not be optimized enough and need further adjustment until the best display effect is achieved. For example, when riding outdoors, if you find that even if you enter the polarization mode, the screen still reflects light at certain angles, you need to fine-tune the excitation electric field parameters according to the actual situation to improve the visibility of the screen.

[0032] The polarized screen has special optical properties. Under the action of different electric field parameters, the screen parameters (such as light transmittance and polarization direction, etc.) will change, thus presenting different screen effects. Due to the existence of the polarized screen, there will be certain differences when users observe the screen-off content of the smart watch through the polarized screen. The polarized screen will have different screen parameters under different electric field parameters and present different screen effects. For example, under certain electric field parameters, the screen may be too dark, the color may be distorted, or the contrast may be insufficient, affecting the user's reading of the screen-off display content. Therefore, it is necessary to appropriately adjust the screen-off display mode such as brightness and color for the smart watch, so as to better obtain the screen-off display content of the smart watch with the participation of the polarized screen. The present application is configured with a first screen-off display mode and a second screen-off display mode, corresponding to the normal mode and polarization mode of the polarized screen.

[0033] In normal mode, first determine the basic layout and element accuracy of the screen display based on the basic parameters of the screen, such as resolution and pixel density, to ensure clear information display. Then, select appropriate color combinations and contrast settings based on color depth and contrast parameters so that the information displayed on the screen, such as time and battery level, can be clearly discernible under normal indoor lighting conditions. At the same time, considering power consumption, the colors should not be too complex or bright. Finally, refer to the brightness range parameter and combine the ambient light intensity detected by the ambient light sensor to automatically adjust the screen display brightness within the lower range of the normal mode brightness range to adapt to different indoor lighting environments and avoid being too bright or too dark.

[0034] For polarization mode, the characteristics of the polarizer layer should be considered. By using the characteristics of the polarization direction and transmittance of the polarizer layer, special screen display patterns or symbols can be designed so that they can be clearly displayed under strong light filtered by the polarizer layer. For example, a pattern that can enhance visibility after interacting with the polarization direction is selected, but it will not be too prominent under ordinary light. At the same time, according to the arrangement characteristics of liquid crystal molecules, a simple graphic or text display method is designed, and the polarization adjustment effect of liquid crystal molecules on light is used to display key information with lower power consumption, so as to achieve the purpose of clearly displaying information and saving power in a strong light environment.

[0035] In some specific embodiments, the user's viewing posture for the smart watch is predetermined; when the light intensity is in a preset low light range, the initial electric field parameters are set to make the polarization effect of the polarization screen on light weakest, and the screen-off display mode of the smart watch is continuously adjusted until the screen-off display content of the smart watch can be clearly seen through the polarization screen in the viewing posture, thereby obtaining a first screen-off display mode.

[0036] Different viewing postures will affect the user's visual effect of the screen display content. For example, when the user lays the smart watch flat to watch, the reflection and refraction of light on the polarized screen will be different from when the watch is tilted at a certain angle, which will affect the user's perception of the clarity of the screen display content. Predetermining the user's viewing posture can provide a fixed reference angle for subsequent adjustment of the screen display mode, so as to more accurately optimize the display effect and ensure that no matter what posture the user is accustomed to watching the watch, they can get a clear visual experience. When the light intensity is in the low light range, the ambient light itself is relatively dim. At this time, if the polarization effect of the polarized screen on the light is too strong, it may further weaken the light reflected from the screen to the user's eyes, making the screen display content difficult to see clearly. Therefore, the initial electric field parameters are set to make the polarization effect of the polarized screen on the light the weakest, so that as much light as possible can pass through the screen and reflect into the user's eyes, improving the visibility of the screen. After setting the polarization effect to the weakest, the display effect can be further optimized by continuously adjusting the smart watch's screen display mode, such as changing the brightness, adjusting the color contrast, optimizing the display font size and style, etc. This process is a process of continuous trial and optimization, the purpose of which is to allow users to clearly see the smartwatch's screen-off display content through the polarized screen under a given viewing posture. In this way, the best screen-off display setting, i.e., the first screen-off display mode, can be found for low-light environments and specific viewing postures, thereby improving the user's experience of viewing smartwatch screen-off information under low-light conditions.

[0037] In some specific embodiments, the maximum light intensity among the predicted light intensities is found, and when the light intensity is at the maximum light intensity, the electric field parameters of the polarized screen and the screen-off display mode of the smart watch are continuously adjusted until the screen-off display content of the smart watch can be clearly seen through the polarized screen in the viewing posture, and the operating time and operating duration of the screen-off display mode are determined in combination with the strong light period to obtain the excitation electric field parameters and the second screen-off display mode.

[0038] Under various lighting conditions, the most challenging situation that smart watches need to deal with is usually when the light intensity is the highest. Because in a strong light environment, the reflected light from the screen may be very strong, making the screen content difficult to see clearly, and the electric field parameters of the polarized screen have a key impact on its display effect under strong light. By finding the maximum light intensity in the predicted light intensity, it can be clear to what extent the polarized screen and the screen-off display mode need to be adjusted under the worst lighting conditions to ensure that the user can clearly see the screen-off content. When the light intensity is at the maximum light intensity, the electric field parameters of the polarized screen and the screen-off display mode of the smart watch are continuously adjusted. Adjusting the electric field parameters can change the polarization characteristics of the polarized screen to light, for example, by adjusting the arrangement of liquid crystal molecules, the screen can better filter out the reflected light in the strong light, enhance the contrast, and improve visibility. At the same time, adjustments to the screen-off display mode may include increasing the screen brightness, changing the color scheme to improve the contrast with the strong light background, and optimizing the layout of the displayed content. This adjustment process is a process of repeated trial and optimization until the user can clearly see the smart watch's screen display content through the polarized screen under the predetermined viewing posture.

[0039] After determining the electric field parameters and screen-off display mode that can clearly display the screen-off content under maximum light intensity, it is necessary to further determine the operating time and operating duration of this display mode in combination with the strong light period. The strong light period refers to the time period of the day when the light intensity is high. The strong light period of each day can be determined by analyzing historical light data or real-time monitoring of changes in ambient light intensity. The operating time of the second screen-off display mode is set according to the strong light period. For example, from the time the sun rises in the morning to noon and before the sun sets in the afternoon, if the light intensity is detected to be at or close to the maximum light intensity, the second screen-off display mode is started. The operating duration is determined according to the specific duration of the strong light to ensure that during the entire strong light period, the smart watch can provide users with clear screen-off display content in an optimized display mode.

[0040] After the above adjustment process, the polarized screen electric field parameters that can achieve clear screen-off display under maximum light intensity are finally determined to be the excitation electric field parameters, and the corresponding screen-off display mode is the second screen-off display mode. The excitation electric field parameters are key parameters for the polarized screen to achieve the best display effect under strong light conditions. They work together with the second screen-off display mode to ensure that users can conveniently and clearly view the screen-off display content of the smart watch during strong light periods and in specific viewing postures, thereby improving the adaptability and user experience of the smart watch in different lighting environments.

[0041] In step 104, since the display effect of the polarized screen is different under different lighting conditions, in order to optimize the screen-off display of the smart watch outdoors, it is necessary to decide whether to apply excitation electric field parameters to the polarized screen according to actual conditions.

[0042] When it is determined that there is no need to apply the excitation electric field parameters, it means that the current outdoor lighting conditions are relatively weak, or under the current lighting conditions, the polarized screen in normal mode can meet the user's needs for clearly viewing the screen content. At this time, the smart watch operates in normal mode, that is, the polarized screen operates according to its default electric field parameters and working mode. At the same time, the smart watch displays the screen content according to the first screen display mode. The first screen display mode is a display mode optimized for low light or normal light environments. For example, in this mode, the screen brightness may be automatically adjusted to a lower level that can still clearly display information based on the low light intensity detected by the ambient light sensor. The color and contrast will also be set to a combination suitable for low light environments to ensure that users can easily see the content displayed on the smart watch screen in relatively dim light outdoors, such as time, date, unread message reminders, etc.

[0043] If it is determined that the excitation electric field parameters need to be applied, this means that the current outdoor environment is in strong light conditions, and the ordinary normal mode and the first screen-off display mode may not allow the user to clearly see the screen-off content. At this time, the smart watch will switch to polarization mode, apply excitation electric field parameters to the polarized screen, change the electric field environment of the screen, and then adjust the arrangement of liquid crystal molecules in the polarized screen, so that the screen can better cope with strong light. For example, it may enhance the ability to filter light in a specific direction, reduce strong light reflection, and improve the contrast and visibility of the screen. At the same time, the smart watch displays the screen-off content according to the second screen-off display mode. The second screen-off display mode is a display mode specially optimized for strong light environments. It may combine the excitation electric field parameters to make multiple adjustments to the screen display, such as further increasing the screen brightness, using more vivid color combinations to enhance the contrast with the strong light background, and optimizing the size and shape of the display font, so that users can clearly see the various information displayed on the smart watch screen in strong light outdoors, and improve the user experience of smart watches in strong light outdoors.

[0044] In some specific embodiments, the energy consumption data of the smart watch is used to analyze whether it is suitable to obtain the actual light intensity at present; if it is suitable, the actual light intensity is compared with the preset high light interval to determine whether to apply the excitation electric field parameters to the polarized screen; if it is not suitable, the excitation electric field parameters are applied to the polarized screen at least during the strong light period. The process is shown in the attached figure. Figure 3As shown. The battery capacity of smart watches is usually limited, and energy management is crucial to ensure their battery life. By analyzing the energy consumption data of smart watches, you can understand the current power consumption of the watch and whether the remaining power can support certain operations. To obtain the actual light intensity, the smart watch needs to use some sensors (such as ambient light sensors) and communication functions (such as interacting with the server to obtain data), which consumes a certain amount of power. Therefore, analyzing the energy consumption data can determine whether there is currently enough power to support the operation of obtaining the actual light intensity, avoiding unnecessary power consumption due to insufficient power or affecting the normal use of the watch.

[0045] When it is determined that the actual light intensity is suitable for acquisition based on the analysis of energy consumption data, the smartwatch will use its built-in sensor or communicate with an external data source (such as a weather service provider) to obtain the actual light intensity value. After obtaining the actual light intensity, it is compared with the preset high light interval. The preset high light interval is a light intensity range pre-set according to the display requirements and performance characteristics of the smartwatch in a strong light environment. For example, greater than 5000 lux is a high light interval. If the actual light intensity is within the preset high light interval, it means that the current environment is in a strong light state. At this time, it is necessary to apply excitation electric field parameters to the polarized screen so that the polarized screen enters the polarization mode to improve the visibility of the screen under strong light; if the actual light intensity is not within the preset high light interval, that is, it is in a relatively weak light environment, then there is no need to apply excitation electric field parameters to the polarized screen, the polarized screen maintains normal mode operation, and the smartwatch displays content according to the corresponding normal mode screen-off display mode.

[0046] When the energy consumption data analysis results show that it is not suitable to obtain the actual light intensity at present, since it is impossible to accurately know the current actual light intensity, in order to ensure the screen display effect of the smart watch during the strong light period, the excitation electric field parameters are applied to the polarized screen at least during the predetermined strong light period (the period in which the light intensity is in the preset high light range selected by the previous analysis of the predicted light intensity). During the strong light period, the ambient light is strong, which is likely to affect the screen display of the smart watch, making the screen content difficult to see clearly. By applying the excitation electric field parameters during the strong light period and allowing the polarized screen to enter the polarization mode, the strong light reflection can be effectively reduced, the contrast and visibility of the screen can be improved, and the user can be ensured that the user can clearly see the information displayed on the smart watch screen during the strong light period. Even when the actual light intensity cannot be obtained, the display performance and user experience of the smart watch can be guaranteed to a certain extent.

[0047] In some specific embodiments, the first off-screen display mode includes: obtaining the actual light intensity and determining whether the actual light intensity is in a high light interval: if not, adjusting the off-screen display brightness of the smart watch according to the actual light intensity; if so, adjusting the off-screen display brightness of the smart watch to a preset high-brightness interval, or displaying in a second off-screen display mode and applying an excitation electric field parameter to the polarized screen. The smart watch detects the light intensity of the surrounding environment in real time through a built-in ambient light sensor, thereby obtaining the actual light intensity value. This sensor can sense the intensity changes of light in the environment and convert it into an electrical signal, which is then recognized and processed by the smart watch system.

[0048] The current environment is in a strong light state. There are two ways to deal with this. One is to adjust the screen display brightness of the smart watch to a preset highlight range. The preset highlight range is a brightness range pre-set to ensure that the screen content is visible in a strong light environment, such as adjusting the brightness to 80% - 100% of the maximum brightness of the screen. Another way is to display in the second screen display mode and apply excitation electric field parameters to the polarized screen. The second screen display mode is a display mode specially optimized for strong light environments, which may include adjusting the color contrast, font size and style of the displayed content, and applying excitation electric field parameters to the polarized screen to put the polarized screen into polarization mode to effectively filter strong light reflections, improve the visibility of the screen, and ensure that users can clearly view the screen information in strong light.

[0049] In some specific embodiments, a liquid crystal layer is sandwiched in the middle of the multi-layer structure of the polarization screen; an electric field is applied to the liquid crystal layer according to the excitation electric field parameters to change the arrangement direction of the liquid crystal molecules, so that the polarization screen only allows light with a specific polarization direction to pass through, thereby reducing the reflected light entering the smart watch, allowing the user to observe the screen-off display content of the smart watch through the polarization screen.

[0050] When an electric field is applied to the liquid crystal layer according to the excitation electric field parameters, the arrangement direction of the liquid crystal molecules will change. Liquid crystal molecules have special physical properties. Under the influence of the electric field, they will rearrange along the direction of the electric field. This is because the liquid crystal molecules themselves have a certain electric dipole moment. Under the action of the electric field force, the molecules will rotate due to the torque, thereby changing their arrangement direction. For example, when there is no electric field, the arrangement of liquid crystal molecules may be chaotic; when a suitable excitation electric field is applied, the liquid crystal molecules will be neatly arranged. After the arrangement direction of the liquid crystal molecules changes, the polarization screen can only allow light with a specific polarization direction to pass through. This is because the liquid crystal layer has different optical properties for light with different polarization directions after changing the molecular arrangement. When light passes through the liquid crystal layer, only the light with the polarization direction that matches the arrangement direction of the liquid crystal molecules can pass smoothly, while the light with other polarization directions will be absorbed, reflected or scattered. In a strong outdoor light environment, the reflected light is usually composed of light with various polarization directions. Through this filtering effect of the polarization screen, the reflected light entering the smart watch can be effectively reduced.

[0051] In some specific embodiments, an electrochromic layer is sandwiched in the middle of the multi-layer structure of the polarized screen; an electric field is applied to the electrochromic layer according to the excitation electric field parameters to cause a redox reaction to change the optical properties, thereby absorbing and scattering part of the polarized light, reducing the reflected light entering the smart watch, and allowing the user to observe the screen-off display content of the smart watch through the polarized screen.

[0052] When an electric field is applied to the electrochromic layer according to the excitation electric field parameters, the electrochromic layer undergoes a redox reaction. Electrochromic materials usually contain some ions or molecules that can be oxidized or reduced under the action of an electric field. Under the influence of the electric field, these ions or molecules undergo electron transfer, thereby changing their chemical state. For example, when metal ions in some electrochromic materials gain electrons (reduction reaction), their electronic structure changes, causing the optical properties of the material to change; and when they lose electrons (oxidation reaction), they also cause changes in optical properties. After the electrochromic layer undergoes a redox reaction, its optical properties change, which is specifically manifested as being able to absorb and scatter light in some polarization directions. Under different redox states, the electrochromic layer has different absorption and scattering characteristics for light. By adjusting the excitation electric field parameters, the redox degree of the electrochromic layer can be controlled, and its absorption and scattering ability for light in different polarization directions can be precisely adjusted. In a strong light environment, the reflected light contains light in various polarization directions. The electrochromic layer effectively reduces the reflected light entering the smart watch by absorbing and scattering light in some polarization directions. By reducing the reflected light entering the smart watch, the contrast of the screen is improved and visibility is enhanced. In this way, users can observe the display content of the smart watch more clearly through the polarized screen.

[0053] In some specific embodiments, it also includes obtaining the predicted ambient temperature of the outdoor area in the first time period; analyzing whether there is an extreme temperature period that exceeds the preset normal temperature range in the predicted ambient temperature; if so, excluding the extreme temperature period at least in the strong light period, and obtaining the actual ambient temperature in the outdoor area, and stopping applying the excitation electric field parameters to the polarization screen when the actual ambient temperature exceeds the normal temperature range. The preset normal temperature range is set according to the normal working temperature range of the smart watch and its polarization screen and other components. Generally speaking, the components of a smart watch can only work stably and reliably within a certain temperature range. For example, the preset normal temperature range may be 0°C to 40°C. The acquired predicted ambient temperature data is analyzed to determine whether there is a situation in which the temperature exceeds this normal temperature range in the first time period, that is, an extreme temperature period.

[0054] At extreme temperatures, the polarized screen may not work properly, or continuing to work may damage it, so at least in the strong light period (the period in which the light intensity is in the preset high light range that was previously screened based on the light intensity), the extreme temperature period is excluded. For example, the originally determined strong light period is from 10 am to 12 noon, but 11 am to 11:30 am is in the extremely high temperature period, so in the subsequent processing, the strong light period is adjusted to 10 am to 11 am and 11:30 am to 12 noon.

[0055] In order to more accurately understand the current environmental conditions, the actual ambient temperature is obtained in real time in outdoor areas through devices such as the built-in temperature sensor of the smart watch. For example, the watch uses its own temperature sensing function to monitor the actual temperature value of the surrounding environment in real time. When the actual ambient temperature obtained exceeds the preset normal temperature range, it means that the current ambient temperature may be unfavorable for the polarized screen. At this time, stop applying the excitation electric field parameters to the polarized screen so that the polarized screen no longer enters the polarization mode and remains in a relatively safe working state. Continuing to apply the excitation electric field parameters may cause the screen to malfunction or accelerate the aging of components. Stopping the application can protect the screen and extend its service life, while also avoiding unnecessary energy consumption.

[0061] The present application proposes a method, system and polarized screen for displaying the screen off of a smart watch. By applying an electric field to an external polarized screen to filter the reflected light in a specific direction, the reflected light entering the smart watch is reduced, so that the user can clearly observe the display content of the smart watch through the polarized screen even in strong light conditions, reduce glare interference, and significantly improve the visibility of the smart watch in complex lighting environments. The reflected light is filtered by an external polarized screen, and various factors are comprehensively considered to determine whether to apply excitation electric field parameters to the polarized screen, thereby reducing unnecessary energy consumption in low-light or non-polarized scenes. The smart watch can adjust the brightness of the screen off display in real time according to the actual light intensity, and cooperate with the switching of the polarized screen working mode. When the light increases, the screen brightness is increased, and the polarized screen is put into polarized mode in a timely manner; when the light decreases, the brightness is reduced, and the polarized screen is switched back to normal mode. The dynamic display strategy ensures that users can have a clear and comfortable visual experience under various lighting conditions.
