FIG. 8 is a schematic flowchart of a method 800 for adjusting brightness provided by an embodiment of the present application. Figure 8 can be applied to the scenario shown in Figure 1 or Figure 2 above, and can specifically correspond to the circuit connection structure shown in Figure 6 or Figure 7, and can also be applied to other application scenarios, which is not limited in this application . Referring to FIG. 8, method 800 may include:

S801. The ambient light sensor acquires ambient light brightness.

It should be understood that the ambient light brightness may be the ambient light brightness within a period of time, and the length of the period of time may be preset or manually set by the user, which is not limited in the present application.

Exemplarily, the ambient light sensor may acquire ambient light brightness for 10s.

Optionally, the ambient light brightness can also be acquired periodically, and the period can be preset or set by the user, which is not limited in this application.

Exemplarily, the ambient light sensor may acquire ambient light brightness every 5s.

S802. The ambient light sensor sends ambient light brightness to the processor. Correspondingly, the processor receives ambient light brightness from the ambient light sensor.

S803. The processor determines first information based on the ambient light brightness.

S804. The processor sends first information to the controller, where the first information is used by the controller to adjust the brightness of the light emitting device. Correspondingly, the controller receives the first information from the processor.

S805. In response to receiving the first information, the controller adjusts the brightness of the light emitting device based on the first information.

In a possible implementation manner, the controller receives the above-mentioned first information (first adjustment instruction), and adjusts the brightness of the light emitting device according to the target brightness.

Exemplarily, the controller then adjusts the brightness of the light emitting device to the above-mentioned target brightness based on the first information.

In the brightness adjustment method of the embodiment of the present application, the processor may obtain the brightness of the ambient light through the ambient light sensor, and send the above-mentioned first information to the controller. The controller may adjust the brightness of the light emitting device based on the first information. Since the ambient light sensor is acquired by the processor, and the controller is always connected to the processor, the controller does not need to be connected to the ambient light sensor. For example, the above-mentioned controller is an 8-bit controller. Since the ambient light sensor must occupy a group System management bus (system management bus, SMbus) pins, and the above 8-bit controller chip only supports two sets of SMbus pins, which are occupied by USB charging and battery chips respectively, so the controller can no longer connect to the ambient light sensor. In other words, in this application, the ambient light sensor can be connected to the processor, and the number of pins of the controller is relatively low, that is, the application can automatically adjust the brightness of the light-emitting device while reducing the number of Capability requirements, thereby reducing the brightness adjustment cost of the light emitting device of the second electronic device.

As an optional embodiment, the processor may judge and determine that the ambient light brightness range in which the ambient light brightness is located does not match the brightness of the light emitting device based on the brightness adjustment strategy of the light emitting device, and will The brightness of the light-emitting device corresponding to the range of ambient light brightness in which the light brightness is located is determined as the above-mentioned target brightness, at least two gears of the brightness of the above-mentioned light-emitting device and the range of ambient light brightness corresponding to the at least two gears. The processor sends first information to the controller, where the first information is a first adjustment instruction, and the first adjustment instruction carries a target brightness corresponding to the ambient light brightness range in which the ambient light brightness is located. The controller may adjust the brightness of the light emitting device to the target brightness based on the above first information.

Table 1 shows the relationship between the gears of the brightness of the light emitting device and the brightness of the ambient light.

The gear of the brightness of the current light-emitting device Ambient brightness The gear of the target brightness of the light emitting device first gear Brightness in dark environment third gear first gear Normal ambient brightness second gear first gear Bright ambient brightness first gear second gear Brightness in dark environment third gear second gear Normal ambient brightness second gear second gear Bright ambient brightness first gear third gear Brightness in dark environment third gear third gear Normal ambient brightness second gear third gear Bright ambient brightness first gear

Exemplarily, the brightness of the above-mentioned light emitting device may include a first level, a second level and a third level, and as the level increases, the brightness of the light emitting device becomes higher. The ambient light brightness may include three brightness ranges: dark ambient brightness, normal ambient brightness, and bright ambient brightness. The higher the brightness of the environment where the first electronic device is located, the darker the brightness of the light-emitting device of the second electronic device or directly turn it off, the lower the brightness of the environment where the first electronic device is located. In order to ensure that the user can see the second electronic device clearly, the user The second electronic device is normally used, and at this time, the brightness of the light emitting device of the second electronic device needs to be adjusted brighter. Therefore, the first level of the brightness of the above-mentioned light-emitting device can correspond to the bright environment brightness in the above-mentioned ambient light brightness, and the second level of the brightness of the above-mentioned light-emitting device can correspond to the normal environment brightness in the above-mentioned ambient light brightness and the brightness of the above-mentioned light-emitting device. The third level of may correspond to the dark ambient brightness in the above-mentioned ambient light brightness.

As shown in Table 1, if the brightness of the current light-emitting device is the first level, and the brightness of the ambient light is the brightness of the dark environment, since the brightness of the ambient light and the brightness of the light-emitting device are too low, the user may have problems that affect the user's use of the second electronic device , so the gear of the brightness of the light-emitting device is adjusted to the third gear corresponding to the brightness of the above-mentioned dark environment. Similarly, as shown in Table 1, when the brightness of the current light-emitting device is the first gear and the ambient light brightness is the normal ambient brightness, the gear of the brightness of the light-emitting device can be adjusted to the second gear corresponding to the above-mentioned normal ambient brightness . When the brightness of the light-emitting device is at the second level and the brightness of the ambient light is at the brightness of the dark environment, the brightness level of the light-emitting device can be adjusted to the third level corresponding to the brightness of the dark environment. When the brightness of the light-emitting device is at the second level and the brightness of the ambient light is at the brightness of the bright environment, the brightness level of the light-emitting device can be adjusted to the first level corresponding to the brightness of the bright environment. When the current brightness of the light-emitting device is the third gear and the ambient light brightness is the normal ambient brightness, the brightness gear of the light-emitting device can be adjusted to the second gear corresponding to the normal ambient brightness. When the brightness of the light-emitting device is at the third level and the brightness of the ambient light is the brightness of the bright environment, the brightness level of the light-emitting device can be adjusted to the first level corresponding to the brightness of the bright environment.

Exemplarily, the brightness of the light-emitting device of the second electronic device is currently at the second level, and if the user turns on the light, the ambient light sensor acquires the brightness of the ambient light and sends the brightness of the ambient light to the processor. The processor receives the brightness of the ambient light as bright ambient brightness, and determines that the bright ambient brightness does not correspond to the second level of brightness of the above-mentioned light-emitting device, and determines that the brightness level of the light-emitting device corresponding to the bright ambient brightness is the first files. The processor may send a first adjustment instruction to the controller, the instruction carries the brightness of the light-emitting device corresponding to the first gear, and the controller may adjust the brightness of the current light-emitting device to the brightness corresponding to the first gear based on the first instruction. brightness.

It should be understood that the third gear is taken as an example here, and the corresponding gear number can also be set according to the adjustment accuracy, which is not limited in the present application.

It should be understood that the more gears, the higher the adjustment accuracy.

Optionally, the processor may also compare the current ambient light brightness with the stored last received ambient light brightness, and determine that the brightness difference between the current ambient light brightness and the last received ambient light brightness is greater than the preset threshold In this case, it is determined that the condition for automatic adjustment of the brightness of the light emitting device is satisfied. At this time, the processor may determine the above-mentioned first information based on the above-mentioned automatic adjustment strategy for the brightness of the light-emitting device, and send the first information to the controller. The above-mentioned conditions for automatically adjusting the brightness of the light-emitting device are satisfied, that is, the brightness difference between the current ambient light brightness and the last received ambient light brightness is too large. If the brightness of the light-emitting device is kept unchanged, user experience may be poor.

Exemplarily, the above-mentioned first electronic device is a notebook computer, the second electronic device is a keyboard, and the light-emitting device is an LED. In a room where the light is turned on at night (the LED brightness is low or turned off), the user turns off the light. The difference in ambient light brightness before and after is too large (the ambient light brightness changes from high to low). If the LED brightness continues to be displayed when the light is turned on, the user may not be able to see the keyboard clearly, interrupting the continuity of the user's use of the keyboard, and poor user experience. .

Exemplarily, the above-mentioned preset threshold may be 120lux, the current ambient light brightness is 15lux, and the last received ambient light brightness is , then since 150lux-15lux>120lux, it can be determined that the above-mentioned conditions for automatic adjustment of the brightness of the light-emitting device are satisfied.

It should be understood that the above preset threshold may be preset or manually set by the user, which is not limited in the present application.

In addition, since the above-mentioned condition for automatic adjustment of the brightness of the light-emitting device can only be satisfied when the brightness difference between the current ambient light brightness and the last received ambient light brightness is greater than a preset threshold, a slight change in the ambient light is avoided. This leads to frequent adjustment of the brightness of the light emitting device of the second electronic device, reduces power consumption, and improves user experience.

In the embodiment of the present application, the processor may obtain the current ambient light brightness through the ambient light sensor, determine the target brightness based on the current ambient light brightness, and send the first information carrying the target brightness to the controller. The controller may adjust the brightness of the light emitting device of the second electronic device to the above-mentioned target brightness based on the first information. In other words, the first information in this application is determined by the processor through analysis and calculation, that is, the controller does not need to perform analysis and calculation, but only needs to perform the action of adjusting the brightness of the above-mentioned light-emitting device to the above-mentioned target brightness. Therefore, this application does not require the logical computing capability of the controller, and since the ambient light sensor does not need to be connected to the controller, this application does not require the number of pins of the controller. In the case of a small number of feet, the present application can still realize the automatic adjustment of the brightness, which effectively reduces the cost.

Optionally, corresponding to the above-mentioned S805, the above-mentioned first information may also include the above-mentioned current ambient light brightness and the brightness adjustment strategy of the light-emitting device, and the brightness adjustment strategy of the light-emitting device includes at least two gears of the brightness of the above-mentioned light-emitting device and the The ambient light brightness range corresponding to at least two gears. In this case, the controller receives the above first information, and may judge whether the ambient light brightness range of the current ambient light brightness matches the current brightness of the light emitting device based on the adjustment strategy of the brightness of the light emitting device in the first information. When the ambient light brightness range of the current ambient light brightness does not match the current brightness of the light-emitting device, the controller adjusts the brightness of the light-emitting device according to the target brightness, the target brightness being the ambient light of the above-mentioned current ambient light brightness. The brightness of the light-emitting device corresponding to the brightness range, because the controller does not need to be connected to the ambient light sensor, so this application can automatically adjust the brightness of the light-emitting device through a controller with a small number of pins, reducing the ability requirements for the controller and reducing Brightness adjustment cost.

Optionally, before sending the first information to the controller, the processor may also determine the adjustment mode of the brightness of the light emitting device, the adjustment mode includes manual adjustment mode and automatic adjustment mode, and the adjustment mode of the brightness of the light emitting device may be automatic adjustment In the case of the mode, the above-mentioned first information is sent to the controller.

In the first possible scenario, the first electronic device is a notebook computer, the second electronic equipment is a keyboard, and the light-emitting device is an LED. When the notebook computer is turned on (for example, it is turned on for the first time or restarted), and the user does not perform any operations on the keyboard Under the default setting, the LED brightness adjustment method of the keyboard is automatically adjusted by default.

In the second possible scenario, if the brightness of the keyboard LED is automatically adjusted before the notebook computer wakes up from hibernation, then after the notebook computer wakes up from hibernation, the brightness of the keyboard LED will be lit according to the brightness that was automatically adjusted last time, The computer is always running normally, and the keyboard LED brightness can always be displayed according to automatic adjustment when the user does not perform any operations on the keyboard, that is, the keyboard LED brightness can be automatically adjusted according to the brightness of the ambient light.

In the above two cases, the processor may send the above first information to the controller.

Optionally, if the adjustment method of the LED brightness of the above-mentioned keyboard is a manual adjustment method, it can be considered that the brightness of the LED of the current keyboard is the brightness required by the user. You can do nothing.

Corresponding to the above-mentioned first possible scenario, if the laptop is turned on and the user presses the keyboard to adjust the brightness of the LED, then the current LED brightness adjustment mode is the manual adjustment mode by default. That is, during the normal operation of the notebook computer, the LED brightness of the keyboard will not change with the brightness of the ambient light. Only when the user operates the keyboard (such as clicking a hot key), the LED brightness of the keyboard will change. Brightness never changes.

Corresponding to the second possible scenario above, if the LED brightness of the keyboard is manually adjusted before the laptop goes to sleep, then after the laptop wakes up from sleep, the LED brightness of the keyboard will be lit according to the last manually adjusted brightness, and if the laptop has been In normal operation, the LED brightness of the keyboard is always displayed according to the manual adjustment, that is, the user clicks the hotkey, the LED brightness of the keyboard will change, otherwise the LED brightness of the keyboard can remain unchanged.

It should be understood that the above two scenarios are only exemplary, and other scenarios may also be used, which are not limited in the present application.

In summary, manual adjustment has a higher priority than automatic adjustment. Regardless of whether the brightness of the light-emitting device is turned off, turned up, or turned down manually, the automatic adjustment will not take effect during the normal operation of the first electronic device. The automatic adjustment can take effect unless the first electronic device is restarted or awakened from sleep.

Optionally, the controller can also determine the adjustment order and adjustment time before adjusting the brightness of the above-mentioned light-emitting device. The time required for the adjustment process; the controller can adjust the brightness of the light-emitting device of the keyboard according to the adjustment steps and the adjustment time. In a dark environment, the sudden change in brightness of the light emitting device of the second electronic device, causing glare and other problems, ensures user experience.

It should be understood that the above adjustment order and adjustment time may be preset or manually set by the user.

Optionally, due to the sensitivity of the human eye to light, the adaptation time from bright to dark is relatively long, and the adaptation time from dark to bright is relatively short. For two scenes from dark to bright, set different adjustment steps and adjustment time.

For example, the adjustment order and adjustment time corresponding to the scene changing from bright to dark may be greater than the corresponding adjustment steps and adjustment time in the scene changing from dark to bright, so as to further improve user experience.

Next to the above S805, after the controller adjusts the brightness of the above-mentioned light-emitting device based on the first information, if the controller does not detect the user's operation instruction on the second electronic device within the first time period, the controller may turn off the above-mentioned light-emitting device.

Exemplarily, the first electronic device is a notebook computer, the second electronic device is a keyboard, and the light emitting device is an LED. Any operation, it can be considered that the user is currently stopping using the laptop, or is currently in a scene that does not need to use the keyboard, such as using the laptop to view documents, pictures, etc., so in order to avoid unnecessary power consumption caused by the LED being turned on all the time, the control at this time The controller can choose to turn off the LED to reduce power consumption.

Optionally, after the controller turns off the light-emitting device of the second electronic device, in order to ensure the experience of the user using the second electronic device next time, the controller detects the user's operation instruction on the second electronic device; The operation instruction of the second electronic device restores the brightness of the light emitting device of the second electronic device. That is, once the controller detects the user's operation on the second electronic device, it can restore the brightness of the light emitting device of the second electronic device to the brightness before the light emitting device is turned off, so as to improve user experience.

Exemplarily, the second electronic device is a keyboard, and the light-emitting device is an LED. After the controller turns off the LED of the keyboard, in order to ensure the continuity of the user's next use of the keyboard, the controller detects the user's operation instruction on the keyboard (click any button) ); in response to the user's operation instruction on the keyboard, restore the brightness of the LED of the keyboard. That is, once the controller detects the user's click operation on the keyboard, it can restore the brightness of the LED of the second keyboard to the brightness before the LED was turned off, so as to avoid the problem that the ambient light brightness is too low and the keyboard cannot be seen clearly, and guarantee the user experience.

Optionally, the above-mentioned first time period may be preset or manually set by the user, which is not limited in this application.

Optionally, after the above automatic adjustment of the brightness of the light emitting device of the second electronic device, the user may also manually adjust the brightness of the light emitting device. That is, in the embodiment of the present application, in addition to the automatic adjustment of the light emitting device, the user can also adjust the brightness of the light emitting device according to his own needs, and the user experience is high.

Table 2 shows the gear switching of the brightness of the light-emitting device in the manual adjustment mode.

The gear of the current LED brightness Number of manual adjustments LED target brightness level first gear once second gear second gear once third gear third gear once first gear first gear twice third gear second gear twice first gear third gear twice second gear

Taking the first electronic device as a notebook computer, the second electronic device as a keyboard, and the light-emitting device as an LED as an example, when the automatic adjustment takes effect, the environment of the notebook computer changes frequently, that is, the brightness of the ambient light changes frequently, causing the keyboard to The LED brightness of the keyboard changes frequently with the brightness of the environment, and the user experience is not good. At this time, the user can manually adjust the LED brightness of the keyboard to a satisfactory brightness according to his own needs, and keep it unchanged, avoiding the automatic adjustment of the LED brightness of the keyboard. Discomfort from frequent changes. As shown in Table 1, if the current level of LED brightness is the first level, the user may increase the brightness of the LED by one level through manual adjustment for better use of the keyboard due to the dark environment, or through Two adjustments realize the adjustment of the brightness of the LED from the first gear to the third gear. Similarly, when the LED is at other brightness levels, the above method can also be used to adjust the gear.

In a possible implementation manner, the user may click the hotkey on the keyboard to manually adjust the LED brightness of the keyboard.

Optionally, the hotkey may be preset or manually set by the user, which is not limited in this application.

Exemplarily, the user can click the key "F3" on the keyboard to increase the LED brightness of the keyboard, or click the key "F5" on the keyboard to decrease the LED brightness of the keyboard. Alternatively, the user can also click the button "Fn" on the keyboard to switch the above-mentioned LED brightness level from low to high or from high to low (that is, switch the brightness level), that is, to realize the adjustment of the LED brightness of the keyboard.

It should be understood that the above-mentioned hotkeys only take the button "F3", the button "F5" and the button "Fn" as examples, and the hotkeys for adjusting the LED brightness can also be other buttons, which are not limited in this application.

It should be understood that the number of gears for adjusting the brightness of the LED through the number of operations (the number of times the hotkey is clicked) shown in Table 1 is only exemplary. The above-mentioned smooth adjustment of the LED brightness level is not limited in this application.

In this embodiment of the present application, the user can manually set parameters such as the above-mentioned hotkey, preset threshold, adjustment order, adjustment time, and first time period through an application (such as a housekeeper application) in the first electronic device.

The layered architecture divides the software system of the first electronic device 100 into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In the embodiment of the present application, the system can be divided into four layers, namely the application layer, the system layer, the driver layer and the hardware layer. It should be understood that the above-mentioned software structure is set as example.

In a possible implementation manner, the above-mentioned first information is a first adjustment instruction, and the first adjustment instruction carries a target brightness corresponding to an ambient light brightness range in which the above-mentioned ambient light brightness is located.

Exemplarily, the housekeeper application may judge whether the ambient light brightness range of the ambient light brightness matches the current brightness of the LED of the keyboard based on the brightness adjustment strategy, and if the ambient light brightness range of the ambient light brightness is in the same range as the keyboard When the current brightness of the LEDs matches, the LED brightness corresponding to the ambient light brightness range where the ambient light brightness is located is determined as the target brightness.

Alternatively, the housekeeper application may also compare the ambient light brightness with the last received ambient light brightness after receiving the ambient light brightness, and determine that the brightness difference between the current ambient light brightness and the last received ambient light brightness is greater than the preset In the case of setting a threshold value, the target brightness is determined from the LED brightness corresponding to the ambient light brightness range in which the current ambient light brightness is located.

In a possible implementation manner, the controller receives the first adjustment instruction, and adjusts the brightness of the LED of the keyboard according to the target brightness carried by the first instruction.

In this application, the housekeeper application may obtain the current ambient light brightness through the ambient light sensor, determine the target brightness based on the current ambient light brightness, and send the first information to the controller. The controller can obtain the above-mentioned target brightness based on the first information, and adjust the LED brightness of the keyboard to the target brightness. In other words, the target brightness in this application is determined by the housekeeper application through analysis and calculation, and the controller does not perform analysis and calculation, but only performs the action of adjusting the LED brightness of the keyboard to the target brightness. Therefore, this application does not require the logic computing capability of the controller, and the ambient light sensor does not need to be connected to the controller, so this application does not require the number of pins of the controller, that is, when the logic computing capability of the controller is weak, the number of pins In less cases, the automatic adjustment of the LED brightness of the keyboard can still be realized, which effectively reduces the cost.

The controller receives the first information, and may judge whether the ambient light brightness range of the current ambient light brightness matches the current brightness of the LED based on the adjustment strategy of the LED brightness in the first information. When the ambient light brightness range of the current ambient light brightness does not match the current brightness of the LED, the controller adjusts the brightness of the LED of the keyboard according to the target brightness. The LED brightness corresponding to the brightness range, since the controller does not need to be connected with the ambient light sensor, the pins of the controller can be reduced, reducing the cost of adjusting the LED brightness of the keyboard.
