[0042] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0043] The following describes a display device brightness control method, device, electronic device, and storage medium according to embodiments of the present disclosure with reference to the accompanying drawings.

[0044] Figure 1 The following is a flow chart of a method for controlling brightness of a display device provided by an embodiment of the present disclosure. Figure 1 As shown, the method includes:

[0045] Step 101: In response to switching the display mode of the display device from a first mode to a second mode, determining a target screen brightness value that matches the current ambient brightness value using a preset association relationship corresponding to the second mode; the display mode is a night mode or a day mode, and the preset association relationship is an association relationship between the ambient brightness value and the screen brightness value, and different display modes correspond to different preset association relationships; wherein, the screen brightness value corresponding to the same ambient brightness value in the night mode is higher than the screen brightness value corresponding to the day mode.

[0046] In some embodiments, different preset association relationships are configured for different display modes, that is, the correspondence between the ambient brightness value and the screen brightness value is different for different display modes. When determining to switch the display mode, the preset association relationship corresponding to the target display mode to be switched (i.e., the second mode) can be obtained, so that the screen brightness value matching the current ambient brightness can be determined based on the obtained preset association relationship.

[0047] In some embodiments, the preset association relationship corresponding to the second mode can be determined according to the preset brightness curve corresponding to the second mode; wherein the preset brightness curve is a fitting curve of the ambient brightness value and the screen brightness value, and the preset brightness curves of different display modes are different; exemplarily, the preset brightness curve is a fitting curve in which the X-axis represents the ambient brightness and the Y-axis represents the screen brightness, and when the value of the X-axis is the current ambient brightness value, the corresponding Y-axis value is the target screen brightness value; the brightness configuration information of the second mode can also be obtained from the configuration information, and the screen brightness value corresponding to the current ambient brightness value can be queried in the brightness configuration information.

[0048] It should be noted that in the embodiment of the present disclosure, since different preset brightness curves are configured for different display modes, and for the same ambient brightness value, the screen brightness value corresponding to the ambient brightness value in the night mode is higher than the screen brightness value corresponding to the ambient light in the day mode. Therefore, when switching the display mode, the screen brightness can be dynamically adjusted, thereby reducing the screen brightness display deviation perceived by the user and improving the user experience.

[0049] In some embodiments, the difference between the screen brightness value corresponding to the same ambient brightness value in the night mode and the screen brightness value corresponding to the same ambient brightness value in the day mode can be called the brightness difference. For example, for the case where the ambient brightness value is 100, the screen brightness value matching the ambient brightness value in the day mode is 120, and the screen brightness value matching the ambient brightness value in the night mode is 135. The brightness difference corresponding to the ambient brightness of 100 is 15. In actual application, the brightness difference corresponding to different ambient brightness values ​​may be different, and the specific brightness difference corresponding to different ambient brightness values ​​may be set according to usage requirements, for example, it may be calculated based on historical data or derived based on a mathematical model, and the embodiments of the present disclosure are not limited to this.

[0050] Step 102: Using the target screen brightness value, adjust the screen brightness of the display device.

[0051] In some embodiments, the target screen brightness value can be calculated by a processor inside the display device and the screen brightness value of the display device can be set to the target screen brightness value; the target screen brightness value of the display device can also be calculated by a vehicle control system and the target screen brightness value can be sent to the display device to control the screen brightness value of the display device to be adjusted to the target screen brightness value.

[0052] In summary, the display device brightness control method provided by the embodiment of the present disclosure realizes dynamic adjustment of screen brightness by determining the target screen brightness value corresponding to the current external ambient light according to the correlation relationship between the corresponding ambient brightness and the screen brightness when the display device switches the display mode, thereby improving the adaptability of the screen brightness to the display mode and avoiding the situation where the screen appears too dark or too bright when switching the display mode, thereby improving user comfort and enhancing user experience.

[0053] Figure 2a FIG. 1 is a flow chart of another method for controlling brightness of a display device provided by an embodiment of the present disclosure. Figure 2a As shown, the method includes:

[0054] Step 2011: In response to a trigger operation on the display device, determine to switch the display mode of the display device from a first mode to a second mode; the trigger operation includes a configuration operation on the display device or the current time meets a preset switching condition, and the display mode is a night mode or a day mode.

[0055] In actual application, the configuration operation for the display device can be a touch operation on the screen, such as clicking a switch button or swiping the screen, or it can be an input switching instruction to the display device, such as inputting a voice control instruction, which is not limited in this embodiment of the present disclosure.

[0056] In some embodiments, when the user performs a touch operation on the screen, the display device may generate a switching request, which may include a target display mode requested by the user to switch to, and the display device may control the screen to switch to the target display mode according to the switching request.

[0057] In some embodiments, when the current time is within a preset time period, it can be determined that the current time meets the preset switching condition; specifically, when it is monitored that the current time is within the preset time period, the display device can query the display mode corresponding to the time period in the corresponding configuration information, thereby controlling the screen to switch to the display mode; exemplarily, the display device is configured to be in night mode from 20:00 to 8:00 the next day, and when it is determined that the current time is within this time period, the current display mode is switched to night mode.

[0058] In some embodiments, when the time between the current time and the last switching exceeds the preset time, it can be determined that the current time meets the preset switching condition; specifically, when it is monitored that the time between the current time and the last switching exceeds the preset time, the display device can query the target display mode that needs to be switched and switch the current display mode to the target display mode. Exemplarily, the time interval for switching between different display modes is 12 hours, and when the time interval between the current time and the last switching to the daytime mode is equal to or greater than 12 hours, the display mode is switched to the night mode.

[0059] In some embodiments, the display device may include multiple screens. In order to adapt to the usage scenarios of different screens, different preset switching conditions can be configured for each screen; exemplarily, a main screen and a sub-screen are set in the vehicle, the main screen is configured to be in night mode from 20:00 to 8:00 the next day, and the sub-screen is configured to be in night mode from 22:00 to 8:00.

[0060] In some embodiments, the night mode may also be referred to as a black mode, and the day mode may also be referred to as a white mode, which is not limited in the embodiments of the present disclosure.

[0061] Step 2012: Determine the preset association relationship corresponding to the second mode based on the preset brightness curve corresponding to the second mode; wherein the preset brightness curve is a fitting curve of the ambient brightness value and the screen brightness value, and the preset association relationship is the association relationship between the ambient brightness value and the screen brightness value; different display modes correspond to different preset association relationships, and the same ambient brightness value corresponds to a higher screen brightness value in the night mode than in the day mode.

[0062] In some embodiments, the preset brightness curve can be a fitting curve of ambient brightness value and screen brightness value; exemplarily, the preset brightness curve is a fitting curve in which the X-axis represents ambient brightness and the Y-axis represents screen brightness. When the value of the X-axis is the current ambient brightness value, the corresponding Y-axis value is the target screen brightness value.

[0063] In some embodiments, corresponding preset brightness curves can be pre-configured for different display modes to adapt to the corresponding display modes; when it is determined to switch the display device from a first mode to a second mode, the corresponding preset brightness curve can be obtained first, and the screen brightness value that matches the current ambient brightness is determined through the preset brightness curve, that is, the target screen brightness value, thereby improving the adaptability of the screen brightness value to the corresponding display mode.

[0064] In actual application, due to the different background colors of different display modes, the same screen brightness will have different presentation effects in different display modes. By configuring different brightness adjustment standards for different display modes, that is, different display modes have different preset brightness curves, the adaptability of the screen brightness to the display mode can be improved, thereby improving the user experience when switching display modes.

[0065] It should be noted that both night mode and day mode are working modes; in the working mode, the screen of the display device can display a working interface under normal working conditions, and the working interface can be used to display the application interface of the display device, such as a map navigation interface, a song playback interface, etc., and can be used to receive user touch operations on the screen.

[0066] Step 2013: Utilize the preset association relationship corresponding to the second mode to determine a target screen brightness value that matches the current ambient brightness value.

[0067] Step 2014: using the target screen brightness value, adjusting the brightness of the target screen in the display device; the target screen is the screen receiving the configuration operation or the screen that meets the preset switching condition at the current time.

[0068] In some embodiments, the display device may include one screen or multiple screens. When the display device includes multiple screens, the target screen brightness value may be used to adjust the brightness of all screens in the display device.

[0069] In some embodiments, the target screen brightness value can also be used to adjust the brightness of the target screen in the display device. For example, a main screen and a secondary screen are set in the front row of the car, and when the user switches the display mode by clicking on the screen, only the brightness of the screen clicked by the user can be adjusted.

[0070] In actual application, the user can decide whether to enable the switching function, that is, the function of automatically switching the display mode, according to usage needs.

[0071] In some embodiments, it may be determined whether the display device has a switching function enabled, and when the switching function is enabled, the steps of the above method may be performed.

[0072] Figure 2b FIG. 1 is a flow chart of another method for controlling brightness of a display device provided by an embodiment of the present disclosure. Figure 2b As shown, the method includes:

[0073] Step 2021: In response to a trigger operation on the display device, determine to switch the display mode of the display device from a first mode to a second mode; wherein the trigger operation is receiving a switching control instruction sent by a network, and the display mode is a night mode or a day mode.

[0074] In some embodiments, the display mode of the display device can be switched from the first mode to the second mode when a switching control command sent by a control center or a terminal device is received. For example, when a user sends a switching request to switch the display mode to the night mode to the vehicle control system through a terminal device such as a mobile phone, the vehicle control system switches the display mode to the night mode.

[0075] In some embodiments, the switching control instruction may carry indication information for indicating a target screen, that is, the switching control instruction is used to indicate which screen's screen brightness is to be adjusted.

[0076] Step 2022: Determine the preset association relationship corresponding to the second mode based on the preset brightness curve corresponding to the second mode; wherein the preset brightness curve is a fitting curve of the ambient brightness value and the screen brightness value, and the preset association relationship is the association relationship between the ambient brightness value and the screen brightness value; different display modes correspond to different preset association relationships, and the same ambient brightness value corresponds to a higher screen brightness value in the night mode than in the day mode.

[0077] In some embodiments, the preset brightness curve can be a fitting curve of ambient brightness value and screen brightness value; exemplarily, the preset brightness curve is a fitting curve in which the X-axis represents ambient brightness and the Y-axis represents screen brightness. When the value of the X-axis is the current ambient brightness value, the corresponding Y-axis value is the target screen brightness value.

[0078] In some embodiments, corresponding preset brightness curves can be pre-configured for different display modes to adapt to the corresponding display modes; when it is determined to switch the display device from a first mode to a second mode, the corresponding preset brightness curve can be obtained first, and the screen brightness value that matches the current ambient brightness is determined through the preset brightness curve, that is, the target screen brightness value, thereby improving the adaptability of the screen brightness value to the corresponding display mode.

[0079] It should be noted that both night mode and day mode are working modes; in the working mode, the screen of the display device can display a working interface under normal working conditions, and the working interface can be used to display the application interface of the display device, such as a map navigation interface, a song playback interface, etc., and can be used to receive user touch operations on the screen.

[0080] Step 2023: Determine a target screen brightness that matches the current ambient brightness value by using the preset association relationship corresponding to the second mode;

[0081] Step 2024: using the target screen brightness value, adjusting the brightness of the target screen in the display device; the target screen is the screen indicated by the switching control instruction.

[0082] In some embodiments, the display device may include one screen or multiple screens. When the display device includes multiple screens, the target screen brightness value may be used to adjust the brightness of all screens in the display device.

[0083] In some embodiments, the target screen brightness value can also be used to adjust the brightness of the target screen in the display device. For example, a main screen and a secondary screen are set in the front row of the car, and when the user switches the display mode by clicking on the screen, only the brightness of the screen clicked by the user can be adjusted.

[0084] In actual application, the user can decide whether to enable the switching function, that is, the function of automatically switching the display mode, according to usage needs.

[0085] In some embodiments, it may be determined whether the display device has a switching function enabled, and when the switching function is enabled, the steps of the above method may be performed.

[0086] In summary, the display device brightness control method provided by the embodiment of the present disclosure realizes dynamic adjustment of screen brightness by determining the target screen brightness value corresponding to the current external ambient light according to the correlation relationship between the corresponding ambient brightness and the screen brightness when the display device switches the display mode, thereby improving the adaptability of the screen brightness to the display mode and avoiding the situation where the screen appears too dark or too bright when switching the display mode, thereby improving user comfort and enhancing user experience.

[0087] The technical solution is further described below in conjunction with specific application examples.

[0088] Figure 3 A flow chart of a method for adjusting the brightness of a vehicle screen provided by an application embodiment of the present disclosure. Figure 3 As shown, the method includes:

[0089] Step 301: The user clicks a switch button set in the vehicle APP, the display device sends a switch instruction for night mode or day mode, and then executes step 303.

[0090] Here, the user chooses to switch to different modes by clicking on pre-configured buttons on the main screen or the sub-screen. When the night mode switch button is clicked, the vehicle control system will receive information about the night mode switch. When the day mode switch button is clicked, the vehicle control system will receive information about the day mode switch.

[0091] The vehicle control system may also switch the display mode to the display mode corresponding to the time period when entering the corresponding time period according to the association between the pre-set time period and the display mode.

[0092] Step 302: The vehicle control system determines whether the screen that triggers the instruction is the main screen or the secondary screen according to the issued instruction, and then executes step 303.

[0093] Here, when the control system receives a switching instruction issued by the user by clicking the screen, the clicked screen is the screen that triggers the instruction.

[0094] Step 303: The vehicle control system determines the mode to be switched according to the issued instruction; and then executes step 304.

[0095] Here, the mode to be switched is the display mode that the screen will enter, and the mode to be switched can be a night mode or a day mode.

[0096] Step 304: load the brightness curve corresponding to the mode to be switched, and calculate the target screen brightness value according to the current ambient light, and then execute step 305.

[0097] Specifically, when it is necessary to switch from night mode to day mode, the brightness curve of day mode is loaded, and the target screen brightness value corresponding to the current ambient light in the brightness curve of day mode is calculated; when it is necessary to switch from day mode to night mode, the brightness curve of night mode is loaded, and the target screen brightness value corresponding to the current ambient light in the brightness curve of night mode is calculated.

[0098] Step 305: Send the calculated target screen brightness value to the screen receiving the trigger instruction, and control the screen receiving the trigger instruction to adjust the brightness according to the target screen brightness value.

[0099] The solution provided by the application embodiment of the present disclosure can automatically switch the brightness curve when switching between black and white modes, and adjust the screen brightness according to the brightness curve and the current ambient brightness value, so as to improve the user experience in this mode without the need for the user to manually adjust the brightness.
