[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0020] Embodiment 1

[0021] Figure 1 : is a flowchart of a dual-screen brightness adjustment method based on a domestic operating system provided in Embodiment 1 of the present invention. This embodiment is applicable to booting a heterogeneous operating system in a multi-core system. The method can be performed by a dual-screen brightness adjustment device based on a domestic operating system, and specifically includes the following steps:

[0022] Step 110: determine whether it is a dual-screen integrated usage scenario based on the mouse activity area and activity duration, and if it is a dual-screen integrated usage scenario, determine the main screen and the sub-screen.

[0023] In this embodiment, the dual-screen comprehensive use scenario may include: Office and learning scenarios: For example, when using Word, communication tools such as WeChat and DingTalk can be moved to the secondary screen to facilitate viewing new messages, while the main screen is focused on typing. During an online meeting, the conference software can be placed on the secondary screen, and the main screen can open a word document for recording, or PDF documents and materials can be browsed on the main screen, while the key points can be recorded on the secondary screen. Design work scenario Designers perform the main design work on the main screen while viewing reference pictures or color samples on the secondary screen, which improves design efficiency and accuracy. Video production and editing scenarios: For video editors who need to view multiple materials or references at the same time, dual screens can provide a larger display area, which is convenient for operating multiple software windows or previewing multiple video clips at the same time. Professional analysis and research scenarios: In professional fields that require processing large amounts of data or performing complex calculations at the same time, dual screens can display different data sets or analysis tools to improve work efficiency. Game and entertainment scenarios: For gamers, a dual-screen setting can provide a better gaming experience. One screen is used for the game itself, and the other screen can display a game guide, map, or other related information.

[0024] In the above dual-screen comprehensive usage scenario, the main screen and the secondary screen are not fixed, but are determined by activity. For example, in an office scenario, when browsing files, the screen displaying the files is the main screen, and when recording, the screen recording the documents is the secondary screen. The focus of the user is constantly changing.

[0025] Therefore, in this embodiment, the qt function based on the operating system can determine the mouse activity area within a period of time, and based on this, determine whether it is a dual-screen comprehensive usage scenario.

[0026] When it is determined to be a dual-screen comprehensive usage scenario, it is necessary to determine the main screen and the sub-screen. Exemplarily, when a peripheral operation is received, a statistical period is set according to a preset duration; the occupancy rate of each screen is determined according to the peripheral operation within the statistical period, and the main screen and the sub-screen are determined according to the occupancy rate. Furthermore, the main screen and the sub-screen can also be determined based on the peripheral operation type and the corresponding occupancy rate, wherein the main screen and the sub-screen can realize identity conversion according to the user's operation. Furthermore, the method can also add the following steps: query the current active process, determine the application according to the active process, and determine the preset duration according to the application. For example: word operation relies more on the keyboard, and its set duration may be longer, while when browsing documents, it mainly relies on mouse operation, and the set duration is shorter.

[0027] Step 120, query the screen brightness of the main screen and the sub-screen, and query the current remaining power of the notebook.

[0028] For example, the newly added interface is used to obtain the brightness function gcm_backlight_helper_get_best_backlight1() for dual-screen notebooks in the domestic operating system, and the brightness adjustment interface of the two screens in the operating system system backlight directory is obtained respectively; and the newly added brightness acquisition function: gpm_brightness_helper_get_value() function is used to obtain the current brightness from the file of the brightness adjustment interface. And the current remaining power of the current notebook is obtained through the power acquisition function.

[0029] Since the brightness is affected by the laptop's battery level, if the brightness is high, the remaining battery level will be consumed quickly, affecting the duration of the screen. Therefore, it is necessary to query the remaining battery level and generate a comprehensive adjustment plan based on the remaining battery level.

[0030] Step 130, generating a brightness adjustment curve according to the current remaining power, the screen brightness of the main screen and the sub-screen and the preset standard brightness, and adjusting the brightness of the main screen and the sub-screen according to the brightness adjustment curve.

[0031] When adjusting the brightness, it is necessary to change it gradually to avoid rapid changes in brightness from irritating the user's eyes. Therefore, in this embodiment, a brightness adjustment curve is generated according to the current remaining power, the screen brightness of the main screen and the sub-screen, and the preset standard brightness. The brightness adjustment curve is generated by comprehensively considering comprehensive factors such as power and target brightness, and the brightness of the main screen and the sub-screen are adjusted respectively according to the brightness adjustment curve.

[0032] This embodiment determines whether it is a dual-screen comprehensive use scenario based on the mouse's active area and activity duration. When it is a dual-screen comprehensive use scenario, the main screen and the sub-screen are determined; the screen brightness of the main screen and the sub-screen is queried, and the current remaining power of the notebook is queried; a brightness adjustment curve is generated based on the current remaining power, the screen brightness of the main screen and the sub-screen, and the preset standard brightness, and the brightness of the main screen and the sub-screen is adjusted according to the brightness adjustment curve. The main screen and the sub-screen can be determined according to the user's operation, and a brightness adjustment curve can be generated according to the power and the current screen brightness, which can make the brightness adjustment smoother and also produce energy-saving effects, extending the use time of the dual-screen notebook. It is particularly suitable for application scenarios where the main and sub-screens are frequently switched. The screen brightness can be adjusted without the user's tedious operations, further improving the user's work efficiency.

[0033] In a preferred implementation of this embodiment, before determining whether it is a dual-screen comprehensive use scenario based on the mouse's active area and activity duration, the method may also add the following steps: read the directory information of the system brightness of the domestic operating system; determine whether the main and sub-screen brightness interface provided by the graphics card can be obtained; accordingly, the determination of whether it is a dual-screen comprehensive use scenario based on the mouse's active area and activity duration can be specifically optimized as follows: when the main and sub-screen brightness interface can be obtained, determine whether it is a dual-screen comprehensive use scenario based on the mouse's active area and activity duration. Exemplarily, the directory information under / sys / class / backlight can be read to obtain the main and sub-screen brightness interface provided by the graphics card, and then determine that the currently used laptop is a dual-screen laptop.

[0034] Embodiment 2

[0035] Figure 2 It is a flow chart of a dual-screen brightness adjustment method based on a domestic operating system provided in the second embodiment of the present invention. This embodiment is optimized on the basis of the above embodiment, and the brightness adjustment curve is generated according to the current remaining power, the screen brightness of the main screen and the sub-screen and the preset standard brightness. The specific optimization is as follows: a duration reference line is generated according to the remaining power and the preset standard brightness; an initial adjustment step is set, an initial curve is generated based on the initial step adjustment step and the screen brightness of the main screen and the sub-screen, and a main screen brightness power area and a sub-screen power brightness area are generated based on the initial curve and the duration reference line; the initial step adjustment step is adjusted, and the sum of the areas of the main screen brightness power area and the sub-screen power brightness area is calculated, wherein the area value of the power brightness area on the right side of the duration reference line is a negative value, so that the sum of the areas of the main screen brightness power area and the sub-screen power brightness area is minimized; a brightness adjustment curve is generated according to the step adjustment step corresponding to the minimum sum of the areas of the main screen brightness power area and the sub-screen power brightness area.

[0036] See also Figure 2 The dual-screen brightness adjustment method based on the domestic operating system includes:

[0037] Step 210: determine whether it is a dual-screen integrated usage scenario based on the mouse activity area and activity duration. If it is a dual-screen integrated usage scenario, determine the main screen and the sub-screen.

[0038] Step 220, query the screen brightness of the main screen and the sub-screen, and query the current remaining power of the notebook.

[0039] Step 230: Generate a duration reference line according to the remaining power and the preset standard brightness.

[0040] Exemplarily, the remaining power available for the screen can be determined based on the proportion of power used by the screen in the remaining power, and a reference line segment can be established as a duration reference line based on the power used per unit time at a preset standard brightness.

[0041] Step 240, setting an initial adjustment step, generating an initial curve based on the initial step adjustment step and the screen brightness of the main screen and the sub-screen, and generating a main screen brightness power area and a sub-screen power brightness area based on the initial curve and the duration reference line.

[0042] The initial adjustment step can be set based on experience, usually set to a minimum value. Based on the adjusted brightness corresponding to the initial step adjustment step and the amount of power required for the time corresponding to the brightness, a curve can be established as the initial curve. Correspondingly, since both the main screen and the sub-screen need to be adjusted, the brightness of the main screen may increase, while the brightness of the sub-screen may decrease. Corresponding initial curves are established respectively. And the area surrounded by the duration reference line generated based on the curve and the above steps is used as the main screen brightness power area and the sub-screen power brightness area. That is, the brightness adjustment decrease is drawn on the right side of the time reference line, and the time is the total adjustment duration, which is a positive value. So that the left side reflects the increased power consumption, and the right side reflects the decreased power consumption. Among them, the adjustment step sizes of the main screen and the sub-screen can be the same or different.

[0043] Step 250, adjust the initial step adjustment step size, calculate the sum of the main screen brightness power area and the sub-screen power brightness area area, wherein the power brightness area area value located on the right side of the duration reference line is a negative value, so that the sum of the main screen brightness power area and the sub-screen power brightness area area is minimized.

[0044] In this embodiment, setting different step sizes can affect power consumption, so an iterative optimization method can be used to continuously adjust the step size, continuously calculate the sum of the main screen brightness power area and the auxiliary screen power brightness area, and obtain the minimum sum by calculation to determine the optimal step size. Furthermore, different step sizes can be set as the optimal step size according to different time periods.

[0045] Furthermore, in order to avoid the impact of too large a step size on the user experience, in this embodiment, the initial adjustment step size can be set to be optimized as follows: the initial adjustment step size interval and the change rate are set according to the screen brightness of the main screen and the secondary screen and the preset standard brightness; the initial adjustment step size is set based on the initial adjustment step size interval and the change rate. By using the above method, the impact of over-emphasizing energy saving on the user experience can be avoided.

[0046] Step 260: Generate a brightness adjustment curve according to the minimum corresponding step adjustment step length of the sum of the areas of the main screen brightness power area and the auxiliary screen power brightness area.

[0047] After the optimal step length is determined, the brightness adjustment curve can be generated using the optimal step length.

[0048] Step 270: Adjust the brightness of the main screen and the sub-screen according to the brightness adjustment curve.

[0049] For example, the on_brightness_changed() function can be used to obtain the target brightness value for adjustment, and the target brightness value can be written into the brightness adjustment interface of the two screens under the operating system background light directory through the set_display_brightness() function. By utilizing the characteristics of the domestic operating system, the brightness of the main screen and the secondary screen can be adjusted quickly.

[0050] This embodiment optimizes the brightness adjustment curve generated according to the current remaining power, the screen brightness of the main screen and the sub-screen and the preset standard brightness as follows: generating a duration reference line according to the remaining power and the preset standard brightness; setting an initial adjustment step, generating an initial curve based on the initial step adjustment step and the screen brightness of the main screen and the sub-screen, and generating a main screen brightness power area and a sub-screen power brightness area based on the initial curve and the duration reference line; adjusting the initial step adjustment step, calculating the sum of the main screen brightness power area and the sub-screen power brightness area, wherein the power brightness area area value located on the right side of the duration reference line is a negative value, so that the sum of the main screen brightness power area and the sub-screen power brightness area area is minimized; generating a brightness adjustment curve according to the step adjustment step corresponding to the minimum sum of the main screen brightness power area and the sub-screen power brightness area area. The brightness adjustment curve can be generated by comprehensively considering the remaining power usage time and the user experience. It can extend the usage time of the dual-screen notebook computer as much as possible on the basis of ensuring the user experience.
