Description

Technical Field

[0001] The present disclosure relates to the field of display control technology, and in particular to a method and device for controlling the brightness of a display screen, and a household appliance. Background Art

[0002] Typically, an air conditioner display primarily displays the current operating status of the air conditioner and the current ambient conditions. In related technologies, to improve the user experience, different levels of brightness can be selected based on the light intensity in the room to suit the user. For example, at noon when the light is strongest, the display brightness can be brightened to allow the user to clearly see the content. However, at night when the light is dim, the display brightness can be lowered to help the user fall asleep.

[0003] However, due to the diversity of actual air conditioner usage scenarios, different lighting conditions in different spaces, and the different materials and colors of air conditioner panels, the detected light sensitivity values ​​will vary. Therefore, it is particularly important to accurately control the brightness of the display based on the light sensitivity value. Summary of the Invention

[0099] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0100] It should be noted that the air conditioner display screen usually mainly displays the current operating status of the air conditioner and the current environmental status. In related technologies, in order to improve the user experience, different levels of brightness can be selected based on the different light intensities in the room to adapt to the user. For example, at noon when the light is strongest, the display brightness is adjusted to brighten so that the user can clearly see the display content. When the light is dark at night, the display brightness can be reduced to help the user fall asleep.

[0101] However, due to the diversity of actual air conditioner usage scenarios, different lighting conditions in different spaces, and the different materials and colors of air conditioner panels, the detected light sensitivity values ​​will vary. Therefore, it is particularly important to accurately control the brightness of the display based on the light sensitivity value.

[0102] In order to solve the above problems, the present disclosure provides a method and device for controlling the brightness of a display screen, and a household appliance.

[0103] Figure 1 This is a flow chart of a method for controlling the brightness of a display screen according to an exemplary embodiment. It should be noted that the method for controlling the brightness of a display screen according to the embodiment of the present disclosure can be applied to household appliances equipped with a display screen, wherein the household appliances can be refrigerators, washing machines, etc. The method for controlling the brightness of a display screen according to the embodiment of the present disclosure can be applied to a device for controlling the brightness of a display screen according to the embodiment of the present disclosure, and the device can be configured in a household appliance. Figure 1 As shown, the method may include the following steps:

[0104] Step 101: Obtain the light sensitivity value of the current display screen's surrounding environment.

[0105] The display screen surrounding environment refers to the environment in which the display screen is located. For example, if the display screen is mounted on an air conditioner, the display screen surrounding environment may be the indoor environment of the room in which the air conditioner is located. The light sensitivity value may be collected by a photosensor equipped with the household appliance, that is, the light sensitivity value of the environment surrounding the display screen at the current moment may be obtained by the photosensor.

[0106] It should be noted that if the household appliance is in operation, the light sensitivity value of the environment around the display screen may be obtained once every preset time period. The preset time period may be determined based on actual application scenarios and is not limited in this disclosure.

[0107] Step 102 : determining a current first calibration light sensitivity threshold and a second calibration light sensitivity threshold; wherein the first calibration light sensitivity threshold and the second calibration light sensitivity threshold are both corrected based on the daily light sensitivity value of the surrounding environment and / or daily weather information.

[0108] The first calibrated light sensitivity threshold refers to the highest calibrated light sensitivity value, and the second calibrated light sensitivity threshold refers to the lowest calibrated light sensitivity value, and both the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are values ​​corrected daily. Since both the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are values ​​corrected based on the daily light sensitivity value of the surrounding environment and / or daily weather information, the obtained first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are more consistent with the actual scene of the current surrounding environment.

[0109] In some embodiments of the present disclosure, the current first calibration light sensitivity threshold and the second calibration light sensitivity threshold refer to the current latest first calibration light sensitivity threshold and the second calibration light sensitivity threshold. It should be noted that the current first calibration light sensitivity threshold may be the first calibration light sensitivity threshold that has been corrected on the same day, or it may refer to the first calibration light sensitivity threshold that has not been corrected on the same day, that is, it may be the first calibration light sensitivity threshold that was corrected yesterday; the current second calibration light sensitivity threshold may be the second calibration light sensitivity threshold that has been corrected on the same day, or it may refer to the second calibration light sensitivity threshold that has not been corrected on the same day, that is, it may be the second calibration light sensitivity threshold that was corrected yesterday.

[0110] In some embodiments of the present disclosure, both the first calibration light threshold and the second calibration light threshold can be modified based on the daily ambient light value, or based on daily weather information, or based on the daily ambient light value and daily weather information. The weather information may include month, season, sunrise time, sunset time, sunny / cloudy / rainy / snowy weather conditions, and other weather conditions.

[0111] As an example, multiple light sensitivity values ​​of the surrounding environment at different time periods on the same day can be obtained. For each time period, the multiple light sensitivity values ​​within this time period are averaged to obtain the average light sensitivity value of each time period. The highest average light sensitivity value in each time period is used as the first calibration light sensitivity threshold for the day, and the lowest average light sensitivity value in each time period is used as the second calibration light sensitivity threshold for the day.

[0112] Step 103 : Control the brightness of the display screen according to the relationship between the light sensitivity value and the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold.

[0113] In some embodiments of the present disclosure, a brightness value corresponding to the light sensitivity value can be determined based on the relationship between the light sensitivity value of the current display screen's surrounding environment and the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold, and the brightness of the display screen can be adjusted to the corresponding brightness value. For example, it can be pre-set that when the light sensitivity value is less than the second calibrated light sensitivity threshold, it corresponds to a brightness value of 1; when the light sensitivity value is greater than the first calibrated light sensitivity threshold, it corresponds to a brightness value of 2; when the light sensitivity value is greater than or equal to the second calibrated light sensitivity threshold and the light sensitivity value is less than or equal to the first calibrated light sensitivity threshold, it corresponds to a brightness value of 3.

[0114] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, the brightness of the display screen is controlled by using a first calibrated light sensitivity threshold and a second calibrated light sensitivity threshold that are corrected based on the light sensitivity value of the current display screen's surrounding environment and / or daily weather information. In this solution, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are values ​​that are corrected daily based on the environment, so the resulting first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are more consistent with actual scenarios, thereby enabling more precise control of the display screen's brightness based on the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold, thereby improving the user experience.

[0115] Next, the correction process of the first calibration light sensitivity threshold and the second calibration light sensitivity threshold will be introduced.

[0116] Figure 2 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 2 As shown, the method includes:

[0117] Step 201: Obtain the light sensitivity value of the current display screen's surrounding environment.

[0118] Step 202 : determining the current first calibration light sensitivity threshold and the second calibration light sensitivity threshold; wherein the first calibration light sensitivity threshold and the second calibration light sensitivity threshold are both corrected based on the daily ambient light sensitivity value and / or daily weather information.

[0119] Step 203 : Control the brightness of the display screen according to the relationship between the light sensitivity value and the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold.

[0120] Among them, steps 201-203 and Figure 1 The implementation of steps 101-103 is the same as that of FIG. 1 and will not be repeated here.

[0121] In some embodiments of the present disclosure, the method further includes a correction process of the first calibration light sensitivity threshold and the second calibration light sensitivity threshold as follows:

[0122] Step 204 : Based on the daily ambient light value and / or daily weather information, the first calibrated light threshold and the second calibrated light threshold are corrected.

[0123] That is to say, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold can be corrected based on the light sensitivity value of the surrounding environment every day, or based on the daily weather information, or based on the light sensitivity value of the surrounding environment every day and the daily weather information.

[0124] As a possible implementation method, based on the light sensitivity value of the surrounding environment every day, correcting the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold may include: obtaining multiple light sensitivity values ​​of the surrounding environment at different time periods on the same day, and for each time period, averaging the multiple light sensitivity values ​​in this time period to obtain the average light sensitivity value of each time period, and then using the highest average light sensitivity value in each time period as the corrected first calibrated light sensitivity threshold, and using the lowest average light sensitivity value in each time period as the corrected second calibrated light sensitivity threshold.

[0125] As another possible implementation method, correcting the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold based on daily weather information may include: constructing a light sensitivity threshold database based on the historical weather information of each day within the historical time period, and the historical first calibrated light sensitivity threshold and the historical second calibrated light sensitivity threshold of each day, matching the weather information of the day with the historical weather information in the light sensitivity threshold database, and using the historical first calibrated light sensitivity threshold corresponding to the historical weather information with the highest matching value with the weather information of the day as the corrected first calibrated light sensitivity threshold, and using the historical second calibrated light sensitivity threshold corresponding to the historical weather information with the highest matching value with the weather information of the day as the corrected second calibrated light sensitivity threshold.

[0126] As another possible implementation method, correcting the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold based on the daily light sensitivity value of the surrounding environment and the daily weather information may include: determining the first time period with the strongest light intensity and the second time period with the lowest light intensity based on the daily weather information; obtaining multiple first light sensitivity values ​​of the surrounding environment at different time points in the first time period, and obtaining multiple second light sensitivity values ​​of the surrounding environment at different time points in the second time period; using the average value of the multiple first light sensitivity values ​​as the corrected first calibrated light sensitivity threshold, and using the average value of the multiple second light sensitivity values ​​as the corrected second calibrated light sensitivity threshold.

[0127] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected according to the light sensitivity value of the surrounding environment every day and / or the daily weather information, so that the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold can be more in line with the actual scene, so that the brightness of the display screen can be more accurately controlled according to the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold, thereby improving the user experience.

[0128] Figure 3 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 3 As shown, based on the above embodiment, the process of correcting the first calibration light sensitivity threshold and the second calibration light sensitivity threshold based on the light sensitivity value of the surrounding environment every day may include:

[0129] Step 301: Acquire multiple light sensitivity values ​​of the surrounding environment on that day.

[0130] As an example, the light sensitivity value of the surrounding environment at the corresponding moment of the day can be collected every 10 minutes based on the photosensor to obtain the light sensitivity value corresponding to each collection moment.

[0131] As another example, two time periods can be pre-set, such as 11:00-13:00 and 0:00-02:00. During these two time periods, the light sensitivity value of the surrounding environment corresponding to the collection time is collected every 10 minutes based on the photosensitive sensor to obtain multiple light sensitivity values.

[0132] Step 302 : Correct the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold in sequence according to the multiple light sensitivity values.

[0133] That is, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected based on multiple light sensitivity values ​​of the day, so that the corrected light sensitivity thresholds can meet the current actual scene.

[0134] As a possible implementation method, if the light sensitivity value of the surrounding environment is collected once every preset time period, the highest value among the multiple light sensitivity values ​​can be determined as the corrected first calibration light sensitivity threshold, and the lowest value among the multiple light sensitivity values ​​can be determined as the corrected second calibration light sensitivity threshold.

[0135] As another implementation method, if the multiple light sensitivity values ​​are multiple light sensitivity values ​​in different time periods, and the different time periods include time periods of strong light and time periods of weak light, the average value of the multiple light sensitivity values ​​in the time period of strong light can be used as the corrected first light sensitivity value, and the average value of the multiple light sensitivity values ​​in the time period of weak light can be used as the corrected second light sensitivity value.

[0136] It should be noted that step 301 and step 302 can be executed in parallel. If multiple light sensitivity values ​​for correcting the first calibration light sensitivity threshold have been obtained, step 302 can be executed to correct the first calibration light sensitivity threshold. At this time, step 301 is still in the execution process. After all light sensitivity values ​​are obtained, step 302 is executed to correct the second calibration light sensitivity threshold.

[0137] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, by obtaining multiple light sensitivity values ​​of the surrounding environment on that day, and according to the multiple light sensitivity values, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected in turn, so that the corrected first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold can be more in line with the lighting conditions of the actual scene on that day, and then the brightness of the display screen can be more accurately controlled according to the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold.

[0138] Figure 4 This is a flow chart of another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 3 In step 301, a plurality of light sensitivity values ​​of the surrounding environment on that day are obtained, and the plurality of light sensitivity values ​​may include m first light sensitivity values ​​and n second light sensitivity values, where m and n are both integers greater than 1. Figure 4 As shown, based on the above embodiment, Figure 3 The implementation of step 301 in the embodiment may include the following steps:

[0139] Step 401: determine a first time period with the strongest light brightness and a second time period with the lowest light brightness.

[0140] In some embodiments of the present disclosure, the first time period with the highest light brightness and the second time period with the lowest light brightness can be pre-set or determined based on the weather conditions of the day. The first time period and the second time period can be the same or different in length.

[0141] As an example, a household appliance can obtain local weather information, such as sunrise and sunset times, and weather conditions, through a Wi-Fi device. Based on this weather information, a preset time period determination model is used to determine a first time period with the highest light brightness and a second time period with the lowest light brightness. The time period determination model has already learned the mapping relationship between daily weather information and the first time period with the highest light brightness and the second time period with the lowest light brightness.

[0142] Step 402: Obtain m first light sensitivity values ​​of the surrounding environment within a first time period.

[0143] Step 403: Obtain n second light sensitivity values ​​of the surrounding environment within a second time period.

[0144] That is, a plurality of light sensitivity values ​​may be acquired in the first time period and the second time period respectively, wherein m and n may be preset or determined according to the first time period and the second time period.

[0145] As an example, if the first time period is 12:00-13:00, the second time period is 0:00-01:00, and m and n are both 6, then the first light sensitivity value at the corresponding moment can be collected and recorded every 10 minutes during the time period of 12:00-13:00 on the same day, and 6 first light sensitivity values ​​can be obtained; and the second light sensitivity value at the corresponding moment can be collected and recorded every 10 minutes during the time period of 0:00-01:00 on the same day, and 6 second light sensitivity values ​​can be obtained.

[0146] In some embodiments of the present disclosure, Figure 3 The implementation process of step 302 may include the following steps:

[0147] Step 404: Determine the highest light sensitivity value of the day based on the m first light sensitivity values.

[0148] As an example, the highest value among the m first light perception values ​​can be used as the highest light perception value of the day. As another example, the average value of the m first light perception values ​​can be used as the highest light perception value of the day.

[0149] Step 405: Determine the lowest light sensitivity value of the day based on the n second light sensitivity values.

[0150] As an example, the lowest value among the n second light sensitivity values ​​can be used as the lowest light sensitivity value for the day. As another example, the average value of the n second light sensitivity values ​​can be used as the lowest light sensitivity value for the day.

[0151] Step 406 : Correct the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold in sequence according to the maximum light sensitivity value and the minimum light sensitivity value.

[0152] In some embodiments of the present disclosure, the highest light sensitivity value may be used as the corrected first calibration light sensitivity threshold, and the lowest light sensitivity value may be used as the corrected second calibration light sensitivity threshold.

[0153] According to the method for controlling the brightness of a display screen according to an embodiment of the present disclosure, by determining a first time period with the strongest light brightness and a second time period with the lowest light brightness on that day, m first light sensitivity values ​​of the surrounding environment in the first time period are obtained, and n second light sensitivity values ​​of the surrounding environment in the first time period are obtained. Based on the m first light sensitivity values, the highest light sensitivity value of the day is determined, and based on the n second light sensitivity values, the lowest light sensitivity value of the day is determined. Then, based on the highest light sensitivity value and the highest light sensitivity value, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected in sequence. In other words, by correcting the first calibrated light sensitivity threshold based on the light sensitivity value in the time period with the strongest light brightness on that day, and correcting the second calibrated light sensitivity threshold based on the light sensitivity value in the time period with the lowest light brightness on that day, the corrected first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold can be made more consistent with the actual scene of the day.

[0154] In actual application scenarios, the obtained light sensitivity value may be inaccurate due to differences in light sensitivity detection adjustments. To avoid this problem, the present disclosure provides another embodiment.

[0155] Figure 5 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 5 As shown, based on the above embodiment, Figure 4 Step 406 in the embodiment may include the following steps:

[0156] Step 501: If the maximum light sensitivity value is less than or equal to the first light sensitivity preset value, the maximum light sensitivity value is determined as the corrected first calibration light sensitivity threshold.

[0157] Step 502: If the highest light sensitivity value is greater than the first light sensitivity preset value, the first light sensitivity preset value is determined as the corrected first calibration light sensitivity threshold.

[0158] In some embodiments of the present disclosure, Figure 4 Step 406 in the embodiment may further include the following steps:

[0159] Step 503: If the lowest light sensitivity value is greater than or equal to the second light sensitivity preset value, the highest light sensitivity value is determined as the corrected second calibration light sensitivity threshold.

[0160] Step 504 : If the lowest light sensitivity value is less than the second light sensitivity preset value, the second light sensitivity preset value is determined as the corrected second calibrated light sensitivity threshold.

[0161] That is to say, the first light sensitivity preset value and the second light sensitivity preset value can be pre-set in the household appliance, wherein the first light sensitivity preset value is the highest light sensitivity value determined based on various scenarios, and the second light sensitivity preset value is the lowest light sensitivity value determined based on various scenarios. In order to avoid the situation where the corrected first calibrated light sensitivity threshold or the second calibrated light sensitivity threshold does not meet the conditions due to the differences in light detection conditions, thereby affecting the brightness adjustment of the display screen, the obtained highest light sensitivity value and the lowest light sensitivity value can be compared with the first light sensitivity preset value and the second light sensitivity preset value, respectively. If the highest light sensitivity value and the lowest light sensitivity value are within the range of the first light sensitivity preset value and the second light sensitivity preset value, it is considered to meet the actual conditions, and the highest light sensitivity value is determined as the corrected first calibrated light sensitivity threshold, and the lowest light sensitivity value is determined as the corrected second calibrated light sensitivity threshold. Otherwise, the preset value is used to correct the light sensitivity threshold.

[0162] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, when the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected in turn according to the maximum light sensitivity value and the minimum light sensitivity value, the maximum light sensitivity value is compared with the first light sensitivity preset value, and the minimum light sensitivity value is compared with the second light sensitivity preset value, so as to avoid the problem that the acquired light sensitivity value does not conform to the actual situation, thereby further ensuring the consistency between the corrected first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold and the actual scene, and thus achieving precise control of the brightness of the display screen.

[0163] Next, another implementation of the correction process of the first calibration light sensitivity threshold and the second calibration light sensitivity threshold will be introduced.

[0164] Figure 6 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 6As shown, in the above embodiment, the process of correcting the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold based on daily weather information may include:

[0165] Step 601: Obtain the weather information of the day.

[0166] The weather information may include sunrise time, sunset time, date of the day, weather (such as sunny, cloudy, rainy, snowy, etc.), and other weather-related information. As an example, when a household appliance is in operation, it can obtain the weather information of the day through a Wi-Fi device.

[0167] Step 602: Based on a preset light sensitivity threshold matching model and according to weather information, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected; wherein the light sensitivity threshold matching model is constructed based on historical weather information of each day in a historical time period, as well as the historical first calibrated light sensitivity threshold and the historical second calibrated light sensitivity threshold of each day.

[0168] Among them, the light sensitivity threshold matching model can be a neural network model that learns the mapping relationship between the historical weather information of each day in the historical time period and the historical first calibrated light sensitivity threshold and the historical second calibrated light sensitivity threshold, or it can be a light sensitivity threshold database constructed based on the historical weather information of each day in the historical time period and the historical first calibrated light sensitivity threshold and the historical second calibrated light sensitivity threshold.

[0169] As a possible implementation method, based on a preset light sensitivity threshold matching model, the implementation process of correcting the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold according to weather information includes: inputting the weather information into the light sensitivity threshold matching model to obtain the target historical first calibrated light sensitivity threshold and the target historical second calibrated light sensitivity threshold with the highest matching degree with the weather information; using the target historical first calibrated light sensitivity threshold as the corrected first calibrated light sensitivity threshold, and using the target historical second calibrated light sensitivity threshold as the corrected second calibrated light sensitivity threshold.

[0170] For example, if the weather information contains multiple data, the weight of each data in the weather information can be pre-set when performing the matching calculation. Based on the difference between the weather information of the day and the data in the historical weather information, as well as the corresponding weights, a weighted calculation can be performed to determine the matching degree between the weather information and each historical weather information.

[0171] In some implementations of the present disclosure, the historical first calibrated light threshold and the historical second calibrated light threshold for each day within the historical time period used to construct the light threshold matching model can be determined based on the daily ambient light value. The process for determining the historical first calibrated light threshold and the historical second calibrated light threshold is consistent with the process for correcting the first calibrated light threshold and the second calibrated light threshold based on the daily ambient light value in the above-mentioned embodiment, and will not be further described here.

[0172] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, by obtaining the weather information of the day, based on a preset light tube threshold matching model, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are corrected according to the weather information, so that the corrected first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold can be more in line with the actual scene, so that the brightness of the display screen can be more accurately controlled according to the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold, thereby improving the user experience.

[0173] Next, the brightness control process of the display will be introduced in detail.

[0174] Figure 7 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 7 As shown, based on the above embodiment, Figure 1 The implementation of step 103 may include:

[0175] Step 701 : determining a target light sensitivity value interval from a plurality of light sensitivity value intervals according to the light sensitivity value; wherein the plurality of light sensitivity value intervals are divided based on a first calibrated light sensitivity threshold and a second calibrated light sensitivity threshold.

[0176] In some embodiments of the present disclosure, the multiple light sensitivity value intervals divided based on the first calibration light sensitivity threshold and the second calibration light sensitivity threshold may be continuous, and the number of the multiple light sensitivity value intervals is greater than or equal to 3. Each light sensitivity value interval corresponds to a brightness value.

[0177] As an example, if the first calibrated light sensitivity threshold is A1 and the second calibrated light sensitivity threshold is AN, A1 to AN can be equally divided into A1, A2, A3, A4 and AN, resulting in 6 light sensitivity value intervals: (0, AN), (AN, A4), (A4, A3), (A3, A2), (A2, A1) and (A1,). Each light sensitivity value interval corresponds to a brightness value, that is, (0, AN) corresponds to brightness value 1, (AN, A4) corresponds to brightness value 2, (A4, A3) corresponds to brightness value 3, (A3, A2) corresponds to brightness value 4, (A2, A1) corresponds to brightness value 5 and (A1,) corresponds to brightness value 6.

[0178] The target light sensitivity value interval refers to the light sensitivity value interval that includes the light sensitivity value of the current surrounding environment. In other words, the light sensitivity value of the current surrounding environment can be compared with each light sensitivity value interval, and the light sensitivity value interval that includes the light sensitivity value of the current surrounding environment can be determined as the target light sensitivity value interval.

[0179] Step 702: Determine a target brightness value corresponding to a target light sensitivity value interval.

[0180] Based on the above example, if the light sensitivity value at the current moment is less than AN, the target light sensitivity value interval is (0, AN), and the target brightness value is brightness value 1; if the light sensitivity value at the current moment is greater than or equal to AN and less than A4, the target light sensitivity value interval is (AN, A4), and the target brightness value is brightness value 2; if the light sensitivity value at the current moment is greater than or equal to A4 and less than A3, the target light sensitivity value interval is (A4, A3), and the target brightness value is brightness value 3, and so on.

[0181] Step 703: Adjust the brightness of the display screen to a target brightness value.

[0182] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, multiple light sensitivity value intervals are determined based on a first calibrated light sensitivity threshold and a second calibrated light sensitivity threshold. According to the light sensitivity value at the current moment, a target light sensitivity value interval is determined from the multiple light sensitivity value intervals, and a target brightness value corresponding to the target light sensitivity value interval is determined. The brightness of the display screen is adjusted to the target brightness value, thereby achieving precise control of the brightness of the display screen and improving the user experience.

[0183] Figure 8 FIG. 1 is a flow chart showing another method for controlling the brightness of a display screen according to an exemplary embodiment. Figure 7 As shown, based on the above embodiment, Figure 1 The implementation of step 103 may include:

[0184] Step 801 : determining a target light sensitivity value interval from a plurality of light sensitivity value intervals according to the light sensitivity value; wherein the plurality of light sensitivity value intervals are divided based on a first calibrated light sensitivity threshold and a second calibrated light sensitivity threshold.

[0185] Step 802 : If the light sensitivity values ​​of the consecutive states all correspond to the same target light sensitivity value interval, then determine the target brightness value corresponding to the target light sensitivity value interval.

[0186] For example, if the light sensitivity values ​​of multiple consecutive states are the light sensitivity values ​​of two consecutive states, step 803 is equivalent to determining the target brightness value corresponding to the target light sensitivity value interval if the target light sensitivity value interval corresponding to the current light sensitivity value is consistent with the target light sensitivity value interval corresponding to the light sensitivity value of the previous state.

[0187] It should be noted that the target light sensitivity values ​​corresponding to the light sensitivity values ​​of the consecutive multiple states are all consistent, wherein the number of light sensitivity values ​​of the multiple states can be pre-set based on the sampling frequency of the light sensitivity values ​​of the actual application scenario.

[0188] In the embodiment of the present disclosure, after step 802 is completed, step 803 is executed.

[0189] Step 803: Adjust the brightness of the display screen to a target brightness value.

[0190] Step 804 : If the light sensitivity values ​​of the consecutive states do not correspond to the target light sensitivity value intervals, the brightness of the display screen remains unchanged.

[0191] That is to say, by judging whether the target light sensitivity value intervals corresponding to the light sensitivity values ​​of multiple consecutive states are consistent, if they are consistent, the brightness of the display screen is adjusted according to the target brightness value; otherwise, the brightness of the display screen is kept unchanged. This can avoid sudden changes in light sensitivity values ​​caused by problems with light detection conditions, thereby further improving the accuracy of display screen brightness control and avoiding frequent adjustments to the brightness of the display screen.

[0192] According to the method for controlling the brightness of a display screen in an embodiment of the present disclosure, after determining the target light sensitivity value interval based on the light sensitivity value of the current surrounding environment, by judging whether the target light sensitivity value intervals corresponding to the light sensitivity values ​​of multiple consecutive states are consistent, the problem of sudden changes in light sensitivity values ​​caused by differences in light sensitivity detection conditions can be eliminated, thereby further improving the accuracy of display screen brightness control and avoiding frequent adjustments to the brightness of the display screen.

[0212] If the highest light sensitivity value is less than or equal to the first light sensitivity preset value, the highest light sensitivity value is determined as the first calibration light sensitivity threshold;

[0215] If the lowest light sensitivity value is less than the second light sensitivity preset value, the second light sensitivity preset value is determined as the second calibration light sensitivity threshold.

[0216] As an example, the first correction unit 942 is further configured to:

[0217] The average value of the m first light sensitivity values ​​is taken as the highest light sensitivity value; and / or,

[0221] Determine the target brightness value corresponding to the target light sensitivity value interval;

[0222] Adjust the brightness of the display to the target brightness value.

[0223] As an example, the control module 930 is further configured to:

[0224] If the light sensitivity values ​​of the consecutive states all correspond to the same target light sensitivity value interval, then the target brightness value corresponding to the first target light sensitivity value interval is determined;

[0225] If the light sensitivity values ​​of multiple consecutive states correspond to different target light sensitivity value intervals, the brightness of the display screen remains unchanged.

[0226] According to the device for controlling the brightness of a display screen in an embodiment of the present disclosure, the brightness of the display screen is controlled by using a first calibrated light sensitivity threshold and a second calibrated light sensitivity threshold that are corrected based on the light sensitivity value of the display screen's surrounding environment at the current moment, as well as the light sensitivity value of the surrounding environment each day and / or daily weather information. In this solution, the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are values ​​that are corrected daily based on the environment, so the resulting first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold are more consistent with actual scenarios, thereby enabling more precise control of the display screen's brightness based on the first calibrated light sensitivity threshold and the second calibrated light sensitivity threshold, thereby improving the user experience.
