[0041] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The main solution of the embodiment of the present invention is: detecting brightness adjustment information, obtaining a target adjustment area of the display screen of the terminal device according to the brightness adjustment information; and adjusting the backlight brightness according to the target adjustment area.

[0043] As Figure 1 shown, Figure 1 is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiment solution of the present invention.

[0044] The terminal in the embodiment of the present invention may be a terminal device with a photographing function such as a smart phone, a tablet computer, a camera, a video camera, an e-book reader, an MP3 (Moving Picture Experts Group Audio Layer III) player, an MP4 (Moving Picture Experts Group Audio Layer IV) player, a portable computer, etc.

[0059] When it is detected that the application is triggered, adjust the backlight brightness of other areas of the display screen except the target adjustment area so that the backlight brightness of each area of the display screen is the same.

[0067] Obtain the target brightness;

[0069] Further, the processor 1001 may call the flash control program stored in the memory 1005 and further perform the following operations:

[0070] If the target adjustment area is not detected to be triggered within the preset time, restore the backlight brightness of the target adjustment area to the brightness before adjustment.

[0071] Referring to Figure 2 , the first embodiment of the present invention provides a method for adjusting the backlight brightness of a terminal device. The terminal device is a mobile terminal, which includes a backlight source and a display screen. The display screen is lit by the backlight source. The backlight source includes a plurality of backlight zones, and each backlight zone corresponds to a plurality of pixel sub-regions. By controlling some of the backlight zones to be lit and combining with the pixel sub-regions, the local backlight brightness can be adjusted. Specifically, the method for adjusting the backlight brightness includes the following steps:

[0072] Step S10: Detect brightness adjustment information, and obtain the target adjustment area of the display screen of the terminal device according to the brightness adjustment information;

[0073] Step S20: Adjust the backlight brightness according to the target adjustment area.

[0074] This embodiment is proposed based on the large power consumption of the mobile terminal. By reducing the power consumption of the backlight source, the power consumption of the mobile terminal can be reduced, and the battery life of the mobile terminal can be improved. Specifically, this embodiment reduces the power consumption of the backlight source by controlling the local lighting of the display screen of the mobile terminal, and highlights the local lighting of the display screen to improve the reminder effect. Based on the functions provided in this embodiment, the setting of the breathing light of the existing terminal device can be saved, and the hardware cost of the terminal device can be reduced.

[0075] Specifically, when the mobile terminal is in the screen-off state, the display screen is in the gray screen state, that is, the backlight brightness of the display screen is in the minimum brightness state. When brightness adjustment information is detected, only the position that needs to be adjusted corresponding to the brightness adjustment information is adjusted, so as to realize the local lighting of the display screen and reduce the power consumption of the backlight source.

[0076] In this embodiment, the brightness adjustment information may be unread information of an application program. For example, when the mobile terminal detects unread information sent to a certain application program, such as unread text messages, etc., in order to prompt the user that there is unread information in the application program and considering energy conservation, only the area where the application program is located is lit; or the brightness adjustment information may also be touch operation information. For example, when the user touches the display screen, only the touched position is lit to display the position that the user needs to view, and at the same time, the lit area is small, saving energy. It can be understood that the above-mentioned brightness adjustment information includes but is not limited to the above two embodiments.

[0077] When brightness adjustment information is detected, obtain a target adjustment area of the display screen of the terminal device according to the brightness adjustment information. Herein, the target adjustment area may be the area corresponding to the brightness adjustment information. For example, when the brightness adjustment information is the unread information of an application program, the target adjustment area is the area where the application program corresponding to the unread information is located. Another example is that when the brightness adjustment information is touch operation information, the target adjustment area is the touch area or the sliding area of the touch operation, etc. After determining the target adjustment area, obtain the pixel sub-area corresponding to the target adjustment area and the maximum pixel gray level value of the pixel sub-area, and adjust the brightness of the pixel sub-area according to the maximum pixel gray level value to adjust the brightness of the target adjustment area.

[0078] Specifically, the method for adjusting the backlight brightness according to the target adjustment area is as follows:

[0079] Adjust the backlight brightness of the target adjustment area so that the backlight brightness of the target adjustment area is greater than the backlight brightness of other areas of the display screen. The effect of highlighting the backlight brightness of the target adjustment area plays a role in reminding the user. While realizing local backlight reminder, the power consumption of the backlight source is reduced.

[0080] Divide the display screen of the terminal device into multiple areas according to the pixel sub-areas, and set at least one target brightness for each area. The target brightness of each area may be different or the same. After determining the target adjustment area, obtain the target brightness corresponding to the target adjustment area, and then adjust the backlight brightness of the target adjustment area according to the target brightness. Herein, the backlight brightness is greater than the brightness of the display screen in the screen-off state. If the brightness of the display screen in the screen-off state is the minimum brightness, then the backlight brightness is greater than the minimum brightness.

[0081] In order to increase the flexibility of energy saving of the mobile terminal, the mobile terminal sets a backlight adjustment mode. After the user turns on the backlight adjustment mode in the mobile terminal, the mobile terminal runs the adjustment process of the backlight in this embodiment. Herein, the backlight adjustment mode includes settings of application programs to be adjusted, target brightness settings, target brightness duration settings, etc., which are set differently according to the different requirements of each user for brightness adjustment. After the backlight adjustment mode is set, turn on the backlight brightness dynamic adjustment switch. In this mode, when the user touches a certain backlight area, the brightness of this area can be automatically adjusted, and other areas of the display screen or the backlight source enter a semi-bright or full-gray state with low power consumption. Or when a certain application program receives information, the area where the application program is located automatically adjusts the brightness, and other areas of the display screen or the backlight source enter a semi-bright or full-gray state with low power consumption.

[0082] Further, after the step of adjusting the backlight brightness according to the target adjustment area, the backlight brightness adjustment method further includes:

[0083] Step S30, if the target adjustment area is not detected to be triggered within a preset time, restore the backlight brightness of the target adjustment area to the brightness before adjustment.

[0084] In order to further reduce the power consumption of the backlight, after adjusting the backlight brightness of the target adjustment area, if the user does not trigger the target adjustment area within a preset time interval, restore the backlight brightness of the target adjustment area to the brightness before adjustment, so that the backlight of the terminal device is in a low-power state and the power consumption of the mobile terminal is reduced.

[0085] For example, when the unread messages of the application on the terminal device make the brightness of the area where the application is located brighter, if the user does not click on the application to read the unread information within a preset time interval, adjust the brightness of the area where the application is located to be the same as the brightness of other areas of the display screen, such as turning off the screen; or, when the display screen of the terminal device is touched by the user to make the brightness of the touch area brighter, if the user does not click on the touch area within a preset time interval, or if the touch area is not detected to be touched again within a preset time interval, or if no other area of the display screen is detected to be touched within a preset time interval, adjust the brightness of the touch area to be the same as the brightness of other areas of the display screen, such as turning off the screen.

[0086] On the contrary, if the target adjustment area is detected to be triggered within a preset time, adjust the brightness of other areas of the display screen so that the brightness of all areas of the display screen is the same.

[0087] In this embodiment, when the terminal device detects brightness adjustment information, by adjusting the partial lighting of the display screen of the terminal device, the power consumption of the backlight of the terminal device is reduced, and further the overall power consumption of the terminal device is reduced, improving the battery life of the terminal device.

[0088] Further, referring to Figure 3 and Figure 4 , a second embodiment of the backlight brightness adjustment method for a terminal device provided by the present invention is based on the above embodiment, where the brightness adjustment information is unread information of an application, and the step of obtaining the target adjustment area of the display screen of the terminal device according to the brightness adjustment information includes:

[0089] Step S11, detecting brightness adjustment information, where the brightness adjustment information is unread information of an application, and determining the position of the application according to the unread information of the application;

[0090] Step S12: Determine the target adjustment area of the display screen of the terminal device according to the location of the application program.

[0091] When the terminal device detects that another terminal device sends communication information to it, determine the received application program according to the type of the communication information. If the communication information has not been read, obtain the location where the application program is located, and determine the target adjustment area of the display screen of the terminal device according to the location where the application program is located. For example, when another terminal device sends a call information to the terminal device, when the call information has not been answered, the terminal device obtains the location of the incoming call application program, determines the target adjustment area according to the location of the incoming call application program, and then adjusts the brightness of the target adjustment area. Specifically, taking Figure 4 as an example, Figure 4 FIG. is a schematic diagram of a display interface of an embodiment of the display screen of the terminal device. The display interface includes multiple application programs, among which the application programs with solid lines are the application programs that have received unread information, and the application programs with dashed lines are the application programs that have not received unread information. Adjust the area where the application program that has received unread information is located, so that the display brightness of the application program represented by the solid line is greater than the display brightness of the application program represented by the dashed line.

[0092] Wherein, the target adjustment area is the area where the application program is located. Specifically, the size of the target adjustment area can be a fixed size, such as a fixed area, or a circle formed with the center of the application program as the origin and a fixed radius, or the size of the icon of the application program displayed on the display screen as the target adjustment area. When the size of the target adjustment area is the size of the icon of the application program displayed on the display screen, the step of determining the target adjustment area of the display screen of the terminal device according to the location of the application program includes: determining the target adjustment area of the display screen of the terminal device according to the location of the application program and the icon of the application program. That is, after determining the application program, obtain the location where the application program is located, and determine the target adjustment area according to the pre-stored icon size of the application program.

[0093] The backlight brightness adjustment method in this embodiment is applied to the unread information reminder scenario. By increasing the display brightness of the application program that has received unread information, it reminds the user that there is unread information on the terminal device. The brightness of other positions on the display screen is low, and the prominent and highlighted display of the application program has a better reminder effect. At the same time, it directly displays the area where the application program is located, allowing the user to more intuitively understand which application program has received information, improving the user experience. At the same time, based on reducing the light-emitting area of the backlight source, the power consumption of the backlight source is reduced, thereby reducing the overall power consumption of the terminal device.

[0094] Further, continue to refer to Figure 3After the step of adjusting the backlight brightness according to the target adjustment area, the following steps are further included:

[0095] Step S40: Detect that the application is triggered, and adjust the backlight brightness of other areas of the display screen except the target adjustment area, so that the backlight brightness of each area of the display screen is the same.

[0096] When the application of the terminal device receives information, the backlight brightness of the area where the application is located is increased to remind the user that there is unread information in the application. If the user triggers the application based on this reminder, the terminal device opens the application for the user to view the unread information. At this time, in order to facilitate the user to view the information interface of the application, the display screen is lit to adjust the backlight brightness of all areas of the display screen to be the same as the backlight brightness of the target adjustment area.

[0097] It can be understood that in order to prevent the user from feeling uncomfortable due to a large brightness difference when other areas except the target adjustment area are lit, in this embodiment, the backlight brightness of other areas is adjusted in a gradually increasing manner so that the user can slowly adapt to the process of increasing brightness. Specifically, the step of detecting that the application is triggered and adjusting the backlight brightness of other areas outside the application includes:

[0098] Detect that the application is triggered, and starting from the application as the center, adjust the backlight brightness of the display screen sequentially towards the edge of the display screen.

[0099] When the application is triggered, it gradually lights up towards the four edges of the display screen with the application as the center, avoiding the impact of "strong light" on the eyes. Specifically, after the application is triggered, obtain the target backlight intensity, and starting from the application as the center, adjust the brightness of the display screen sequentially towards the edge of the display screen with the target intensity.

[0100] Further, referring to Figure 5 A third embodiment of the backlight brightness adjustment method for a terminal device is provided by the present invention. Based on the above second embodiment, when the detected brightness adjustment information includes unread information of multiple applications, the step of obtaining the target adjustment area of the display screen of the terminal device according to the brightness adjustment information includes:

[0101] Step S13: Obtain the priority of each application in the unread information of the multiple applications;

[0102] Step S14: Determine the target adjustment area according to the position of the application with a higher priority.

[0103] The terminal device includes multiple application programs. When there is unread information in multiple application programs, if the backlight areas of all the application programs with unread information are lit, it cannot play the role of reducing display power consumption. Therefore, in this embodiment, the priorities of the multiple application programs are set. When there is unread information in multiple application programs, the target application program to be reminded is determined according to the priorities of the multiple application programs. For example, the priorities of each application program in the unread information of the multiple application programs are obtained, and the application program with a higher priority is determined as the target application program. The target adjustment area is determined according to the position of the target application program, and the actual target adjustment area is the position where the target application program is located.

[0104] Among them, the priorities of the multiple application programs can be specifically set by default. For example, application programs such as incoming call applications, text message applications, and WeChat are sorted from high to low in sequence. The priorities of the multiple application programs can also be set by the user according to requirements, such as the importance of the application programs, or the priorities of the application programs are automatically generated in real time.

[0105] In the case where the priorities of the application programs are automatically generated in real time, the processor of the terminal device has an AI memory function. During the process of the user using the terminal device, the usage habits of the user are recorded to determine the frequently used application programs, and the priorities of the frequently used application programs are set higher than those of the infrequently used application programs; or the number of unread messages is read, and the priorities of the application programs with more unread messages are set higher than those of the application programs with fewer unread messages. It can be understood that the setting methods of the priorities of each application program in this embodiment include but are not limited to the above-listed embodiments.

[0106] In this embodiment, by adjusting the backlight brightness of the area where the application program with a higher priority is located to remind the unread information of the application program with a higher priority, it can not only play an important reminder role but also ensure low power consumption of the terminal device.

[0107] Refer to Figure 6 and Figure 7 , the fourth embodiment of the method for adjusting the backlight brightness of the terminal device provided by the present invention is based on the above first embodiment. The brightness adjustment information is touch operation information. The step of obtaining the target adjustment area of the display screen of the terminal device according to the brightness adjustment information includes:

[0108] Step S16, obtaining the touch area corresponding to the touch operation information;

[0109] Step S17, determining the target adjustment area according to the touch area.

[0110] When the display screen of a terminal device has not been triggered for a long time, in order to save power, it generally enters the screen-off state. When the user triggers the terminal device again, the terminal device is awakened. In general terminal devices, such as when unlocking with a fingerprint, the terminal device is awakened. In this embodiment, in order to prevent the display screen of the terminal device from being lit when the user accidentally touches the fingerprint collection area, thereby consuming the power of the terminal device, when the terminal device collects the unlocking fingerprint but does not detect a touch operation on the display screen, the backlight of the terminal device is in the lowest power consumption state, and the brightness of the display screen is the lowest brightness (gray). When a touch operation information is detected, the terminal device adjusts the brightness according to the touch area corresponding to the touch operation information, only lights up the area touched by the user, and locally lights up the display screen to reduce the display power consumption of the display screen of the terminal device. For Figure 7 example, Figure 7 FIG. Figure 7 is a schematic diagram of a display interface of another embodiment of the display screen of a terminal device. The display interface includes a plurality of application programs. Among them, the application programs on the display screen are marked with dotted lines, and the areas touched on the display screen are marked with solid lines. When the terminal device detects that the user touches the display screen, it adjusts the brightness of the target adjustment area corresponding to the touch operation, and locally lights up the display screen, so that the brightness of the area marked with a solid line is greater than the brightness of the area marked with a dotted line.

[0111] Among them, the touch operation includes one or more of a click operation and a slide operation. For example, when the user clicks on the display screen, the position clicked is sensed by a sensor, and then the touch area is determined. Another example is that when the user slides the display screen, the sliding area is detected by a sensor, and then the sliding area is determined as the touch area.

[0112] In this embodiment, when the display screen of the terminal device is touched, the display power consumption of the terminal device is reduced by locally lighting up the touched part and not lighting up other positions.

[0113] The present invention also provides a terminal, which includes a memory, a processor, and a backlight brightness adjustment program stored on the memory and executable on the processor. When the backlight brightness adjustment program is executed by the processor, it implements each embodiment of the backlight brightness adjustment method described above.

[0114] The present invention also provides a computer-readable storage medium, on which a backlight brightness adjustment program is stored. When the backlight brightness adjustment program is executed by a processor, it implements each embodiment of the backlight brightness adjustment method described above.

[0115] It should be noted that, in this document, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or system comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or system. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or system comprising that element.

[0117] Through the description of the above embodiments, those skilled in the art can clearly understand that the above embodiment methods can be implemented by means of software plus a necessary general hardware platform. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation.
