[0017] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] It should be understood herein that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction rather than having any limiting meaning.

[0020] Based on the description of the above background technology, the related technology also has the following situations:

[0021] When users adjust the brightness of the vehicle's display screen, the display screen brightness can be adjusted manually or automatically according to the ambient light. During automatic adjustment, the display screen will sense the light intensity of the environment through the light sensor, and then look up the table according to the light intensity to determine the corresponding target screen brightness value, and adjust the current screen brightness value to the target screen brightness value to achieve automatic adjustment of the screen brightness.

[0022] However, under the premise of a certain ambient brightness, the automatically adjusted screen brightness value is certain, and different users have different usage habits. A single brightness adjustment value may not meet the user's personalized needs. At this time, the screen brightness may not conform to the user's usage habits, and the user needs to perform manual fine-tuning. At this time, the manual adjustment mode will be entered and the automatic adjustment mode will be turned off. When the automatic brightness is manually selected again, the brightness is adjusted according to the original automatic adjustment strategy, resulting in the brightness after automatic adjustment still not meeting the user's needs. The user still needs to perform manual fine-tuning, which brings a bad user experience.

[0023] It can be seen that there is a certain degree of mutual exclusivity between automatic adjustment and manual adjustment of display brightness in the related technology. The automatic adjustment strategy cannot remember user habits. Under a certain ambient brightness, the user is required to manually fine-tune the screen brightness each time. This is not smart enough and provides users with a poor user experience.

[0024] The brightness adjustment method, electronic device and vehicle of the display screen provided in the embodiment of the present application, when the current brightness adjustment mode is the automatic adjustment mode, determines the initial environment brightness level according to the initial environment brightness; when a manual adjustment operation is detected, keeps the automatic adjustment mode turned on, and determines the manually adjusted target brightness value and the current environment brightness level; when the current environment brightness level is different from the initial environment brightness level, refits the current brightness curve corresponding to the current environment brightness level according to the target brightness value to obtain a first updated brightness curve, and automatically adjusts the brightness of the display screen according to the first updated brightness curve and the real-time environment brightness value after waking up from sleep. When a user's manual adjustment operation is detected in the automatic adjustment mode, the current brightness curve corresponding to the current environment brightness level is refitted according to the manually adjusted target brightness value to obtain a first updated brightness curve that is more in line with the user's usage habits. After the display screen is awakened from sleep, the brightness of the display screen is automatically adjusted according to the first updated brightness curve and the real-time environment brightness value, so as to provide users with the display screen brightness that best meets the user's usage habits in different environments and improve the user's usage experience.

[0025] The brightness adjustment method of a display screen provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0026] In some embodiments, Figure 1 As shown, a method for adjusting the brightness of a display screen includes steps 101 to 103.

[0027] Step 101: In response to the current brightness adjustment mode being the automatic adjustment mode, determining an initial ambient brightness level according to the initial ambient brightness.

[0028] In specific implementation, in the manual adjustment mode, the brightness of the display screen is completely dependent on the user's operation of the brightness adjustment control, and the brightness adjustment is completed when the user stops operating the brightness adjustment control. Therefore, the brightness value in the manual adjustment mode will meet the user's usage needs and truly reflect the user's usage habits.

[0029] In the automatic adjustment mode, the display brightness (also called screen brightness) can be automatically adjusted according to the environment. The basis for the automatic adjustment can be the brightness adjustment relationship table shown in Table 1:

[0030] Table 1 Brightness adjustment relationship table

[0031] Real-time ambient brightness Display brightness [0,200) 30 [200,400) 40 [400,1000) 55 [1000,3000) 80 [3000,+∞) 100

[0032] As can be seen from Table 1, the mechanism of automatically adjusting the brightness using the brightness adjustment relationship table is that when the real-time ambient brightness is within a certain interval, the display brightness is adjusted to the brightness value corresponding to the interval. For example, when the real-time ambient brightness is 700 nit, the display brightness is adjusted to 55 nit. In order to ensure the accuracy of the adjustment, the difference method can also be used to determine a more accurate display brightness value.

[0033] In the automatic adjustment mode, in order to adjust the brightness more accurately, the basis for automatic adjustment of the display brightness can also be as follows: Figure 2 The initial brightness adjustment curve shown is divided into 4 different ambient brightness levels for adjusting the display brightness. Because the impact on the display brightness is different in different ambient brightness ranges, the corresponding adjustment ratio (the corresponding curve slope is different), and the maximum display brightness is set to 100nit.

[0034] After turning on the automatic adjustment mode, you first need to determine the initial ambient brightness level based on the initial ambient brightness, so as to determine the initial brightness curve to be used when automatically adjusting the display brightness (the default brightness curve when no refitting is performed, and the curve after the last refitting after refitting), and automatically adjust the display brightness according to the initial brightness curve and the real-time ambient brightness. At this time, since there is no interference from manual adjustment by the user, it is temporarily determined that the use of the initial brightness curve for automatic adjustment of the display brightness can meet the user's needs and can meet the user's usage experience.

[0035] Step 102: In response to detecting a manual adjustment operation, maintaining the automatic adjustment mode on, and determining a manually adjusted target brightness value and a current environment brightness level.

[0036] In specific implementation, if the user's manual adjustment operation is monitored during the automatic adjustment process, it means that the user is not very satisfied with the automatically adjusted display brightness and the user needs to fine-tune the display brightness. At this time, a different strategy is adopted from the related technology. When the user makes manual adjustment, the automatic adjustment mode is kept on, but the brightness control manually adjusted by the user is responded to first, and the target brightness value of the manual adjustment and the current ambient brightness level at the current moment are determined to determine the adjustment curve used during automatic adjustment, so as to provide data support for the subsequent re-fitting of the curve.

[0037] Step 103: In response to the current ambient brightness level being different from the initial ambient brightness level, the current brightness curve corresponding to the current ambient brightness level is refitted according to the target brightness value to obtain a first updated brightness curve, and the display brightness is automatically adjusted according to the first updated brightness curve and the real-time ambient brightness value after waking up from sleep.

[0038] In specific implementation, when the user's manual adjustment operation is monitored, the external environment may have changed to a certain extent due to changes in time and place, resulting in a change in the ambient brightness level, so it is first necessary to determine whether the current ambient brightness level is consistent with the initial ambient brightness level.

[0039] If the current environment brightness level is inconsistent with the initial environment brightness level, if the initial environment brightness level is Figure 2 The first ambient brightness level in the current ambient brightness level is Figure 2 The second environment brightness level in indicates that the user's current environment has become darker than the initial environment. At this time, it is necessary to determine the current brightness curve corresponding to the current environment brightness level. The current brightness curve is the curve segment in the initial brightness curve corresponding to the second environment brightness level, that is, Figure 2 The initial brightness curve is located in the curve segment within the second environment brightness level range. At this time, it is necessary to determine the initial brightness value before manual adjustment in the automatic adjustment mode according to the current brightness curve, and determine the re-fitting strategy by comparing the initial brightness value and the target brightness value.

[0040] If the target brightness value is greater than or equal to the initial brightness value, it means that the brightness during automatic adjustment is too low. Users are more accustomed to using brighter display brightness and need to increase the brightness as the adjustment direction. Therefore, it is necessary to ensure that the first updated brightness curve obtained after refitting is higher than the initial brightness curve. The first updated brightness curve after adjustment is as follows: Figure 2 As shown in the brightness increase curve in , it is higher than that means that under the same ambient brightness value, the value of the first updated brightness curve is greater than the value of the initial brightness curve. The first ambient brightness curve after adjustment is more in line with the user's usage habits for the display brightness. The re-fitting method includes directly translating the initial brightness curve. The translation distance is the brightness difference between the initial brightness value and the target brightness value. The translation direction is upward. It is simple and efficient. While ensuring that the user's usage habits are met, the computing resources occupied are reduced. The re-fitting method also includes determining the historical manual adjustment data that is higher than the initial brightness curve (including the target brightness value of this adjustment), and performing curve fitting according to the historical manual adjustment data. The first updated brightness curve after fitting is closer to the user's usage habits, has a better fitting effect, and improves the user's usage experience.

[0041] If the target brightness value is less than the initial brightness value, it means that the brightness during automatic adjustment is too high. Users are more accustomed to using a darker display brightness, and need to lower the brightness as the adjustment direction. Therefore, it is necessary to ensure that the first updated brightness curve obtained after refitting is lower than the initial brightness curve. The first updated brightness curve after lowering is as follows: Figure 2As shown in the brightness reduction curve in , it is lower than that under the same ambient brightness value, the value of the first updated brightness curve is lower than the value of the initial brightness curve. The lowered first ambient brightness curve is more in line with the user's usage habits for the display brightness. The re-fitting method includes directly translating the initial brightness curve. The translation distance is the brightness difference between the initial brightness value and the target brightness value. The translation direction is upward. It is simple and efficient. It ensures that the user's usage habits are met while reducing the occupation of computing resources. The re-fitting method also includes determining the historical manual adjustment data that is lower than the initial brightness curve (including the target brightness value of this adjustment), and performing curve fitting according to the historical manual adjustment data. The first updated brightness curve after fitting is closer to the user's usage habits, has a better fitting effect, and improves the user's usage experience.

[0042] After the first updated brightness curve is fitted, since the user manually adjusts the screen brightness at this time, the brightness is not automatically adjusted at the current moment to ensure that the current brightness meets the user's needs. After the user turns off the screen and wakes up the display again, the display brightness is automatically adjusted according to the first updated brightness curve and the real-time ambient brightness value, thereby providing users with the display brightness that best suits their usage habits in different environments and improving the user experience.

[0043] The brightness adjustment method of the display screen provided in the embodiment of the present application, when the user's manual adjustment operation is detected in the automatic adjustment mode, the current brightness curve corresponding to the current environment brightness level is refitted according to the manually adjusted target brightness value to obtain a first updated brightness curve that is more in line with the user's usage habits. After the display screen is awakened from sleep, the brightness of the display screen is automatically adjusted according to the first updated brightness curve and the real-time environment brightness value, so as to provide the user with the display screen brightness that best meets the user's usage habits in different environments and improve the user's usage experience. And the value of the automatic brightness adjustment in this automatic adjustment mode can be directly changed, and there is no need to fit the curve according to the user's historical usage habits when the automatic adjustment mode is enabled next time. The data of this manual adjustment is more in line with the user's usage habits this time, giving the user a better usage experience.

[0044] In some embodiments, the method for adjusting the brightness of a display screen further includes:

[0045] In response to the current environment brightness level being the same as the initial environment brightness level, the initial brightness curve corresponding to the initial environment brightness level is refitted according to the current brightness value to obtain a second updated brightness curve, and the brightness is automatically adjusted according to the second updated brightness curve.

[0046] In specific implementation, if the current ambient brightness level is consistent with the initial ambient brightness level, and is as follows Figure 2The first ambient brightness level shown indicates that the current ambient brightness is high, and the ambient brightness when the user's manual operation is detected is slightly different from the initial ambient brightness, both of which are within the brightness range corresponding to the first ambient brightness level. At this time, the initial brightness value before manual adjustment in the automatic adjustment mode is determined directly according to the curve segment of the initial brightness curve within the first ambient brightness level range, and the re-fitting strategy is determined by comparing the initial brightness value with the target brightness value.

[0047] If the target brightness value is greater than or equal to the initial brightness value, it means that the brightness during automatic adjustment is too low. Users are more accustomed to using brighter display brightness and need to increase the brightness as the adjustment direction. Therefore, it is necessary to ensure that the second updated brightness curve obtained after refitting is higher than the initial brightness curve. The second updated brightness curve after adjustment is as follows: Figure 2 As shown in the brightness adjustment curve, it is higher than that under the same ambient brightness value, the value of the second updated brightness curve is greater than the value of the initial brightness curve. The second ambient brightness curve after adjustment is more in line with the user's usage habits for the display brightness. The re-fitting methods include directly translating the initial brightness curve and performing curve fitting based on historical manual adjustment data, both of which can make the second updated brightness curve more in line with the user's usage habits and improve the user's usage experience.

[0048] If the target brightness value is less than the initial brightness value, it means that the brightness during automatic adjustment is too high. Users are more accustomed to using a darker display brightness, and need to lower the brightness as the adjustment direction. Therefore, it is necessary to ensure that the second updated brightness curve obtained after refitting is lower than the initial brightness curve. The second updated brightness curve after lowering is as follows: Figure 2 As shown in the lowered brightness curve, the lower value indicates that under the same ambient brightness value, the value of the first updated brightness curve is less than the value of the initial brightness curve, and the lowered second ambient brightness curve is more in line with the user's usage habits for the display brightness. The re-fitting methods include directly translating the initial brightness curve and performing curve fitting based on historical manual adjustment data, both of which can make the second updated brightness curve more in line with the user's usage habits and improve the user's usage experience.

[0049] After the second updated brightness curve is fitted, since the user manually adjusts the screen brightness at this time, the brightness is not automatically adjusted at the current moment to ensure that the current brightness meets the user's needs. After the user turns off the screen and wakes up the display again, the display brightness is automatically adjusted according to the second updated brightness curve and the real-time ambient brightness value, thereby providing users with the display brightness that best suits their usage habits in different environments, thereby improving the user experience.

[0050] In some embodiments, the method for adjusting the brightness of a display screen further includes:

[0051] In response to the automatic adjustment mode being turned off, the first updated brightness curve is restored to the default brightness curve, or the second updated brightness curve is restored to the default brightness curve.

[0052] In specific implementation, after the new brightness curve is fitted, the brightness of the display screen can be automatically adjusted according to the new brightness curve that is more in line with the user's usage habits. However, if the user turns off the automatic adjustment mode, it means that the user does not need to use automatic brightness adjustment at this time. After the user turns on the automatic adjustment mode again, the user's usage habits may have changed. Therefore, after the user turns on the automatic adjustment mode again, the default brightness curve needs to be used for automatic brightness adjustment. Therefore, it is necessary to restore the brightness curve when the automatic adjustment mode is turned off. If the re-fitted brightness curve is the first updated brightness curve, the first updated brightness curve is restored to the default brightness curve. If the re-fitted brightness curve is the second updated brightness curve, the second updated brightness curve is restored to the default brightness curve to ensure that the brightness can be automatically adjusted according to the default brightness curve after the automatic adjustment mode is turned on next time, and the new brightness curve is fitted according to the default brightness curve to ensure that the brightness curve that meets the user's current usage habits can be determined to improve the user experience.

[0053] In some embodiments, the method for adjusting the brightness of a display screen further includes:

[0054] In response to not detecting the manual adjustment operation, the brightness of the display screen is adjusted according to the ambient brightness value and an initial brightness curve corresponding to the initial ambient brightness level.

[0055] In specific implementation, if no manual adjustment operation of the user is detected during the automatic adjustment process, it means that the brightness adjustment according to the initial brightness curve can meet the user's needs, and the brightness of the display screen can be adjusted according to the ambient brightness value and the initial brightness curve corresponding to the initial ambient brightness level. When the brightness is automatically adjusted, Figure 2 As shown, the initial brightness curve can be regarded as a multi-segment function. Because different ambient brightness levels have different sensitivities to ambient brightness, the change in the same ambient brightness value corresponds to different changes in display brightness at different ambient brightness levels. That is, the slope of each segment of the segmented function can be different to ensure the most accurate automatic brightness adjustment and improve the user experience.

[0056] In some embodiments, Figure 3 As shown, the current brightness curve corresponding to the current environment brightness level is refitted according to the target brightness value to obtain a first updated brightness curve, including steps 301 to 303.

[0057] Step 301: Determine an initial brightness value corresponding to the current environment brightness level before manual adjustment.

[0058] During specific implementation, since the ambient brightness level has changed, if the change process is from the first ambient brightness level to the second ambient brightness level, it is necessary to use the formula of the curve segment in the initial brightness curve within the second ambient brightness level to calculate the initial brightness value. The current ambient brightness is used as the input of the formula for the curve segment within the second ambient brightness level, and the corresponding output value is the initial brightness value, which represents the brightness of the display screen during automatic adjustment before manual adjustment.

[0059] Step 302: Determine the adjustment direction according to the target brightness value and the initial brightness value before manual adjustment.

[0060] In some embodiments, determining the adjustment direction according to the target brightness value and the initial brightness value before manual adjustment includes:

[0061] Step 3021: In response to the target brightness value being greater than or equal to the initial brightness value, increasing the brightness is used as an adjustment direction.

[0062] In specific implementation, manual adjustment includes two situations: increasing and decreasing. The manual adjustment result data is shown in Table 2:

[0063] Table 2 Manual adjustment result data table

[0064]

[0065] It can be seen that if the current ambient brightness level is the first ambient brightness level, the initial brightness value before manual adjustment determined according to the current ambient brightness value and the current brightness curve is 70nit. If the target brightness value after manual adjustment is 92nit at this time, the target brightness value is greater than the initial brightness value, indicating that the user feels that the display is dark, and manually brightens the display. If the display brightness needs to be increased, then increasing the brightness is used as the adjustment direction.

[0066] Step 3022: In response to the target brightness value being less than the initial brightness value, lowering the brightness is used as an adjustment direction.

[0067] During specific implementation, if the current ambient brightness level is the second ambient brightness level, the initial brightness value before manual adjustment determined according to the current ambient brightness value and the current brightness curve is 52nit, if the target brightness value after manual adjustment is 37nit at this time, then the target brightness value is less than the initial brightness value, indicating that the user feels that the display is brighter and manually dims the display. If the display brightness needs to be reduced, then lowering the brightness will be used as the adjustment direction.

[0068] The adjustment direction determines the relationship between the new brightness curve after refitting and the current brightness curve. If the adjustment direction is to increase the brightness, it means that the new brightness curve is above the current brightness curve, and users are more accustomed to using a brighter display brightness. If the adjustment direction is to decrease the brightness, it means that the new brightness curve is below the current brightness curve, and users are more accustomed to using a darker display brightness.

[0069] After determining the adjustment direction, it is necessary to continue to determine the data source for fitting the new brightness curve. In this case, it is necessary to determine the historical target brightness value in the historical manual adjustment data according to the adjustment direction. If the adjustment direction is to increase the brightness, it means that the user prefers a brighter display brightness at this time, and a new brightness curve located above the current brightness curve needs to be fitted. Therefore, the historical manual adjustment data in the historical manual adjustment data that is greater than the data point on the current brightness curve at the same ambient brightness is determined as the historical target brightness value. If the adjustment direction is to decrease the brightness, it means that the user prefers a darker display brightness at this time, and a new brightness curve located below the current brightness curve needs to be fitted. Therefore, the historical manual adjustment data in the historical manual adjustment data that is less than the data point on the current brightness curve at the same ambient brightness is determined as the historical target brightness value. Determining the historical target brightness value according to the adjustment direction can ensure that the data source for fitting the new brightness curve is more in line with the user's brightness usage habits in the current scene, thereby improving the user's usage experience.

[0070] Step 303: refit the current brightness curve according to the adjustment direction and the historical target brightness value to obtain a first updated brightness curve.

[0071] In some embodiments, the current brightness curve is refitted according to the adjustment direction and the historical target brightness value to obtain a first updated brightness curve, including steps 3031 and 3032.

[0072] Step 3031: In response to the adjustment direction being brightness increase, historical brightness increase values ​​are determined in historical manual adjustment data, and curve fitting is performed according to the historical brightness increase values ​​to obtain a first updated brightness curve.

[0073] In specific implementation, if the adjustment direction is to increase the brightness, the target brightness value is greater than or equal to the initial brightness value, indicating that the brightness during automatic adjustment is too low. Users are more accustomed to using brighter display brightness, and need to increase the brightness as the adjustment direction. Therefore, it is necessary to ensure that the first updated brightness curve obtained after refitting is higher than the initial brightness curve. The first updated brightness curve after the increase is as follows: Figure 2 As shown in the increased brightness curve, it is higher than that indicating that under the same ambient brightness value, the value of the first updated brightness curve is greater than the value of the initial brightness curve. The increased first ambient brightness curve is more in line with the user's usage habits of the display brightness.

[0074] When refitting the brightness curve, the historical increased brightness value is determined in the historical manual adjustment data, where the historical increased brightness value is the part of the historical manual adjustment data that is greater than the data point on the current brightness curve under the same ambient brightness, that is, the part of the historical manual adjustment data that is higher than the initial brightness curve (including the target brightness value of this adjustment), and the curve is fitted according to the historical increased brightness value. The first updated brightness curve after fitting is closer to the user's usage habits, has a better fitting effect, and improves the user experience.

[0075] Step 3032: In response to the adjustment direction being brightness reduction, historical brightness reduction values ​​are determined in the historical manual adjustment data, and curve fitting is performed according to the historical brightness reduction values ​​to obtain a first updated brightness curve.

[0076] In specific implementation, if the target brightness value is less than the initial brightness value, it means that the brightness during automatic adjustment is too high. The user is more accustomed to using a darker display brightness, and needs to lower the brightness as the adjustment direction. Therefore, it is necessary to ensure that the first updated brightness curve obtained after refitting is lower than the initial brightness curve. The first updated brightness curve after lowering is as follows: Figure 2 As shown in the brightness reduction curve, it is lower than that under the same ambient brightness value, the value of the first updated brightness curve is less than the value of the initial brightness curve. The lowered first ambient brightness curve is more in line with the user's usage habits of the display brightness.

[0077] When refitting the brightness curve, the historical lowered brightness value is determined in the historical manual adjustment data, where the historical lowered brightness value is the part of the historical manual adjustment data that is smaller than the data point on the current brightness curve under the same ambient brightness, that is, the part of the historical manual adjustment data that is lower than the initial brightness curve (including the target brightness value of this adjustment), and the curve is fitted according to the historical lowered brightness value. The first updated brightness curve after fitting is closer to the user's usage habits, has a better fitting effect, and improves the user experience.

[0078] After the first updated brightness curve is fitted, since the user manually adjusts the screen brightness at this time, the brightness is not automatically adjusted at the current moment to ensure that the current brightness meets the user's needs. After the user turns off the screen and wakes up the display again, the display brightness is automatically adjusted according to the first updated brightness curve and the real-time ambient brightness value, thereby providing users with the display brightness that best suits their usage habits in different environments and improving the user experience.

[0079] In some embodiments, automatically adjusting the brightness of the display screen according to the first updated brightness curve and the real-time ambient brightness value includes:

[0080] A target backlight brightness value corresponding to the real-time environment brightness value is determined according to the first updated brightness curve, and the backlight brightness of the display screen is adjusted to the target backlight brightness value.

[0081] In a specific implementation, for example, if the first updated brightness curve is Figure 2 In the brightness increase curve, the real-time ambient brightness value is used as the input of the horizontal axis, and the corresponding output value of the vertical axis is the target backlight brightness value. The backlight brightness of the display is adjusted to the target backlight brightness value, so that the brightness of the display can be adjusted to the brightness that meets the user's usage habits, thereby improving the user experience.

[0082] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
