Referring to fig. 4, the key 10211 may include: keyboard cap 10, scissors foot 20, scissors foot plummer 30, silica gel button 40, conducting film 50 and bottom plate 60. In the embodiment of the present application, the setting mode and the setting position of each component in the key 10211 are not described in detail, and reference may be made to the structure of the current key 10211. The fallboard 10 is for receiving a user's depression, and the scissor legs 20 are for supporting and rebounding the fallboard 10. The scissors foot platform 30 is used to carry the scissors feet 20, and the scissors feet 20 can slide on the scissors foot platform 30 in a horizontal direction.

In order to improve user experience, a light emitting device and a controller are arranged in the keyboard 102, and the controller can control the light emitting device to be turned on or off or change the brightness intensity, so that keys or a panel of the keyboard can display different brightness, and the brightness of the keyboard 102 is ensured to be matched with the ambient brightness. The controller may be, for example, an Embedded Controller (EC), the light emitting device may include, but is not limited to, a Light Emitting Diode (LED), an Organic Light Emitting Diode (OLED), a quantum dot light emitting diode (QLED), and the like, and the following embodiments describe the light emitting device as an LED.

In order to adapt to the surrounding environment, the brightness of the LEDs of the keyboard 102 may be adjustable, and the user may manually adjust the brightness of the LEDs of the keyboard by using the user, or the controller may automatically control the brightness of the LEDs of the keyboard based on the ambient light data acquired by the ambient light sensor, so as to achieve automatic adjustment of the brightness of the LEDs of the keyboard.

For the manner of manually adjusting the brightness of the LED of the keyboard by the user, the user may press at least one key in the key area shown in fig. 3, and the controller detects the pressing operation of the user and controls the LED to be turned on, turned off or the brightness to be strong or weak in response to the pressing operation.

The controller 1021 is connected to the ambient light sensor 1022 and the LED1024, and acquires ambient light data through the ambient light sensor 1022, so as to adjust the brightness of the LED1024 of the keyboard 102 according to the ambient light data. The memory 1023 is used to store parameters for adjusting the brightness of the LED1024, strategies for adjusting the brightness of the LED1024, etc., and may also be used to store one or more computer programs comprising instructions. The power supply 1025 supplies power to the keyboard 102 and its various components (e.g., the controller 1021, the memory 1023, the LEDs 1024, etc.).

Fig. 8 is a flowchart illustrating a brightness adjustment method 800 according to an embodiment of the present disclosure. Fig. 8 may be applied to the scenarios shown in fig. 1 or fig. 2, and may specifically correspond to the circuit connection structure shown in fig. 6 or fig. 7, and may also be applied to other application scenarios, which is not limited in this application. Referring to fig. 8, a method 800 may include:

s801, the ambient light sensor acquires ambient light brightness.

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

Illustratively, the ambient light sensor may acquire an ambient light level of 10 s.

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

Illustratively, the ambient light sensor may acquire the ambient light level every 5 s.

S802, the ambient light sensor sends ambient light brightness to the processor. Correspondingly, the processor receives the ambient light level 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, and the first information is used for the controller to adjust the brightness of the light-emitting device. Correspondingly, the controller receives 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 one possible implementation, the controller receives the first information (first adjustment instruction) and adjusts the brightness of the light emitting device according to the target brightness.

Illustratively, the controller adjusts the brightness of the light emitting device to the target brightness based on the first information.

According to the brightness adjusting method, the processor can obtain the ambient light brightness through the ambient light sensor and send the first information to the controller. The controller may adjust the brightness of the light emitting device based on the first information. Because the ambient light sensor is obtained by the processor, and the controller and the processor are always kept connected, the controller does not need to be connected with the ambient light sensor, such as the above controller is an 8-bit controller, because the ambient light sensor must monopolize a set of system management bus (SMbus) pins, and the 8-bit controller chip only supports two sets of SMbus pins, which are respectively occupied by the USB charging and the battery chip, the controller cannot be connected with the ambient light sensor. In other words, the ambient light sensor can be connected to the processor in the present application, and the requirement on the number of pins of the controller is low, that is, the present application can automatically adjust the brightness of the light emitting device, and simultaneously reduce the requirement on the capability of the controller, thereby reducing the brightness adjustment cost of the light emitting device of the second electronic device.

As an alternative embodiment, the processor may determine, based on a brightness adjustment policy of the light emitting device, the brightness of the light emitting device corresponding to the ambient light brightness range in which the current ambient light brightness is located as the target brightness, and determine, when it is determined that the ambient light brightness range in which the current ambient light brightness is located does not match the brightness of the light emitting device, at least two steps of the brightness of the light emitting device and the ambient light brightness ranges corresponding to the at least two steps. The processor sends first information to the controller, wherein the first information is a first adjusting instruction, and the first adjusting instruction carries a target brightness corresponding to an environment light brightness range where the environment light brightness is located. The controller may adjust the luminance of the light emitting device to a target luminance based on the first information.

The first table shows the relationship between the shift of the brightness of the light emitting device and the ambient light brightness.

Current position of light emitting device brightness	Brightness of ambient light	Target brightness shift of light emitting device
			First gear	Brightness of dark surroundings	Third gear
First gear	Brightness of the general environment	Second gear
			First gear	Brightness of bright environment	First gear
Second gear	Brightness of dark environment	Third gear
			Second gear	Brightness of the general environment	Second gear
Second gear	Brightness of bright environment	First gear
			Third gear	Brightness of dark environment	Third gear
Third gear	Brightness of general environment	Second gear
			Third gear	Brightness of bright environment	First gear

Illustratively, the luminance of the light emitting device may include a first stage, a second stage, and a third stage, and the luminance of the light emitting device is higher as the shift stage is higher. The ambient light brightness may include three brightness ranges of dark ambient brightness, normal ambient brightness, and bright ambient brightness. The higher the brightness of the environment where the first electronic device is located is, the darker the brightness of the light-emitting device of the second electronic device is or the light-emitting device of the second electronic device is directly turned off, and the lower the brightness of the environment where the first electronic device is located is, so that the user can see the second electronic device clearly, the normal use of the second electronic device by the user is guaranteed, and at the moment, the brightness of the light-emitting device of the second electronic device needs to be adjusted to be bright. The first step of the brightness of the light emitting device may correspond to a bright ambient brightness among the ambient light brightness, the second step of the brightness of the light emitting device may correspond to a normal ambient brightness among the ambient light brightness, and the third step of the brightness of the light emitting device may correspond to a dark ambient brightness among the ambient light brightness.

As shown in table one, if the current brightness of the light emitting device is the first level and the ambient light brightness is the dark ambient brightness, since the ambient light brightness and the brightness of the light emitting device are both too low, the user may have a problem that the user may affect the second electronic device, so the gear of the brightness of the light emitting device is adjusted to the third gear corresponding to the dark ambient brightness. Similarly, as shown in the table i, when the brightness of the current light-emitting device is the first level and the ambient light brightness is the normal ambient brightness, the level of the brightness of the light-emitting device may be adjusted to the second level corresponding to the normal ambient brightness. When the brightness of the current light emitting device is the second level and the ambient light brightness is the dark ambient brightness, the level of the brightness of the light emitting device can be adjusted to the third level corresponding to the dark ambient brightness. Under the condition that the brightness of the current light-emitting device is the second gear and the ambient light brightness is the bright ambient brightness, the gear of the brightness of the light-emitting device can be adjusted to the first gear corresponding to the bright ambient brightness. When the brightness of the current light-emitting device is the third gear and the ambient light brightness is the ordinary ambient brightness, the gear of the brightness of the light-emitting device can be adjusted to the second gear corresponding to the ordinary ambient brightness. When the brightness of the current light emitting device is the third level and the ambient light brightness is the bright ambient brightness, the level of the brightness of the light emitting device may be adjusted to the first level corresponding to the bright ambient brightness.

For example, when the brightness of the light emitting device of the second electronic device is in the second level, if the user turns on the lighting lamp, the ambient light sensor obtains the ambient light brightness, and sends the ambient light brightness to the processor. The processor receives the ambient light brightness as bright ambient brightness, determines that the bright ambient brightness does not correspond to the second gear of the brightness of the light-emitting device, and determines that the gear of the brightness of the light-emitting device corresponding to the bright ambient brightness is the first gear. The processor may send a first adjustment instruction to the controller, where the instruction carries 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.

It should be understood that only three gears are taken as an example here, and in addition, the corresponding gear number may be set according to the adjustment precision, 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 further compare the current ambient light brightness with a stored last received ambient light brightness, and determine that the condition for automatically adjusting the brightness of the light emitting device is satisfied in a case where it is determined that a brightness difference between the current ambient light brightness and the last received ambient light brightness is greater than a preset threshold. At this time, the processor may determine the first information based on the automatic adjustment policy of the brightness of the light emitting device, and transmit the first information to the controller. The above-mentioned condition for satisfying the automatic adjustment of the brightness of the light emitting device, 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 continuously kept unchanged, it may cause a poor user experience.

For example, the first electronic device is a notebook computer, the second electronic device is a keyboard, the light-emitting device is an LED, and when the user turns off the lighting lamp indoors (when the LED is turned off or is turned off) at night, the user may not see the keyboard clearly if the user continues to display the light at the LED luminance when the lighting lamp is turned on because the difference between the front and the back of the ambient light luminance is too large (the ambient light luminance changes from high to low), and the user may use the keyboard continuously, which results in poor user experience.

For example, the 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 may be determined that the above-mentioned condition for automatically adjusting the brightness of the light emitting device is satisfied.

It should be understood that the preset threshold may be preset or may be manually set by a user, and this application is not limited thereto.

In addition, under the condition that the brightness difference between the current ambient light brightness and the ambient light brightness received last time is larger than the preset threshold value, the condition of automatic brightness adjustment of the light-emitting device can be met, so that frequent brightness adjustment of the light-emitting device of the second electronic device caused by slight change of the ambient light is avoided, power consumption is reduced, and user experience is improved.

In the embodiment of the 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 luminance of the light emitting device of the second electronic device to the target luminance based on the first information. In other words, the first information in the present application is determined by the processor through the analysis calculation, that is, the controller may perform only the operation of adjusting the luminance of the light emitting device to the target luminance without performing the analysis calculation. So this application does not ask for the logic computing power of controller, and because the ambient light sensor need not be connected with the controller, so this application also does not require to the pin quantity of controller, and is weaker promptly at controller logic computing power, under the less condition of pin quantity, this application still can realize the automatically regulated to luminance, effectively the cost is reduced.

Optionally, corresponding to the step S805, the first information may further include the current ambient light brightness and a brightness adjustment policy of the light emitting device, where the brightness adjustment policy of the light emitting device includes at least two gears of the brightness of the light emitting device and ambient light brightness ranges corresponding to the at least two gears. In this case, the controller receives the first information, and may determine 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 policy of the brightness of the light emitting device in the first information. Under the condition that the ambient light brightness range where the current ambient light brightness is located is not matched with 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 is the brightness of the light-emitting device corresponding to the ambient light brightness range where the current ambient light brightness is located, and the controller does not need to be connected with the ambient light sensor, so that the brightness of the light-emitting device can be automatically adjusted through the controller with the small number of pins, the requirement on the capacity of the controller is lowered, and the brightness adjusting cost is lowered.

Optionally, before sending the first information to the controller, the processor may further determine an adjustment manner of the brightness of the light emitting device, where the adjustment manner includes a manual adjustment manner and an automatic adjustment manner, and may send the first information to the controller if the adjustment manner of the brightness of the light emitting device is the automatic adjustment manner.

In a first possible scenario, the first electronic device is a notebook computer, the second electronic device is a keyboard, the light emitting device is an LED, and when the notebook computer is turned on (for example, turned on for the first time or restarted), and a user does not perform any operation on the keyboard, the LED brightness adjustment mode of the keyboard is automatically adjusted by default.

In a second possible scenario, if the brightness of the LED of the keyboard is automatically adjusted before the laptop is awakened from the sleep mode, after the laptop is awakened from the sleep mode, the brightness of the LED of the keyboard is turned on according to the brightness automatically adjusted last time, and when the laptop is normally operated all the time, and the user does not perform any operation on the keyboard, the brightness of the LED of the keyboard can be displayed all the time according to the automatic adjustment, that is, the brightness of the LED of the keyboard can be automatically adjusted according to the brightness of the ambient light.

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

Optionally, if the adjustment mode of the brightness of the LED of the keyboard is a manual adjustment mode, the brightness of the LED of the current keyboard may be considered as the brightness required by the user, and in order to ensure the user's requirement, the brightness of the LED of the current keyboard may not be changed, that is, the processor may not perform any operation.

Corresponding to the first possible scenario, if the notebook computer is turned on, and the user presses the keyboard to adjust the brightness of the LED, the current adjustment mode of the brightness of the LED is determined as a manual adjustment mode. That is, in the normal operation process of the notebook computer, the LED brightness of the keyboard does not change with the change of the brightness of the ambient light, and only when the user operates the keyboard (for example, clicks a hot key), the LED brightness of the keyboard changes, otherwise the LED brightness of the keyboard does not change all the time.

Corresponding to the second possible scenario, if the LED brightness of the keyboard is manually adjusted before the notebook computer sleeps, after the notebook computer sleeps and wakes up, the LED brightness of the keyboard is turned on according to the brightness manually adjusted last time, and if the notebook computer normally operates all the time, the LED brightness of the keyboard is always displayed according to the manual adjustment, that is, the user clicks a hot key, the LED brightness of the keyboard is changed, otherwise, the LED brightness of the keyboard may not be changed all the time.

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

In summary, manual adjustment has a higher priority than automatic adjustment. Whether the brightness of the light emitting device is turned off, turned up, or turned down manually, the automatic adjustment will not be effective during normal operation of the first electronic device. The automatic adjustment may not take effect unless the first electronic device is restarted or sleep awake.

Optionally, the controller may further determine, before adjusting the brightness of the light emitting device, an adjustment order representing the number of times the brightness of the light emitting device is adjusted before and after the adjustment and an adjustment time representing a time required for each two consecutive adjustment processes; the controller may adjust the brightness of the light emitting devices of the keypad according to the adjustment order and the adjustment time. The problems that under the dark environment, the brightness of the light-emitting device of the second electronic device suddenly changes, dazzling and the like are caused are avoided, and user experience is guaranteed.

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

Optionally, since the human eye is sensitive to light, the adaptation time from bright to dark is longer, and the adaptation time from dark to bright is shorter, the adjustment order and the adjustment time may also be set differently for two scenes, namely, from bright to dark and from dark to bright.

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

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

Exemplarily, the first electronic device is a notebook computer, the second electronic device is a keyboard, the light-emitting device is an LED, and after the controller adjusts the LED brightness of the keyboard based on the first information, if the user does not perform any operation on the keyboard within 15s, the user may be considered to be currently stopping using the notebook computer, or be currently in a scene where the keyboard is not needed, for example, the user views documents, pictures, and the like using the notebook computer, so that in order to avoid unnecessary power consumption caused by the LED being turned on all the time, the controller may select to turn off the LED, thereby reducing the power consumption.

Optionally, after the controller turns off the light emitting device of the second electronic device, to ensure the user's experience of using the second electronic device next time, the controller detects an operation instruction of the user on the second electronic device; and restoring the brightness of the light-emitting device of the second electronic equipment in response to the operation instruction of the user on the second electronic equipment. That is, once the controller detects the operation of the second electronic device by the user, the brightness of the light emitting device of the second electronic device can be restored to the brightness before the light emitting device is turned off, so as to improve the user experience.

Illustratively, the second electronic device is a keyboard, the light-emitting device is an LED, and after the controller turns off the LED of the keyboard, the controller detects an operation instruction (clicking any key) of the keyboard by the user to ensure the continuity of the next use of the keyboard by the user; and restoring the brightness of the LED of the keyboard in response to the operation instruction of the user on the keyboard. The controller detects the click operation of the user on the keyboard, the brightness of the LED of the first keyboard can be restored to the brightness of the LED before the LED is closed, the problem that the keyboard cannot be seen clearly due to too low ambient light brightness is avoided, and user experience is guaranteed.

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

Alternatively, after the brightness of the light emitting device of the second electronic device is automatically adjusted as described above, the user may also manually adjust the brightness of the light emitting device. That is, in the embodiment of the present application, besides the automatic adjustment of the light emitting device, the user can also adjust the brightness of the light emitting device according to the own requirement, and the user experience is high.

And the second table shows the gear switching of the brightness of the light-emitting device in the manual adjustment mode.

Current LED brightness gear	Number of manual adjustments	LED target brightness gear
			First gear	At a time	Second gear
Second gear	At a time	Third gear
			Third gear	At a time	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 example, under the condition that the automatic adjustment is effective, because the environment where the notebook computer is located frequently changes, that is, the ambient light brightness frequently changes, the LED brightness of the keyboard frequently changes along with the ambient brightness, and the user experience is not good, at this time, the user can manually adjust the LED of the keyboard to the satisfactory brightness according to the self-demand, and keep the LED brightness unchanged, thereby avoiding discomfort caused by the automatic frequent change of the LED brightness of the keyboard. As shown in table one, if the current gear of the LED brightness is the first gear, the user may increase the brightness of the LED by one gear through one manual adjustment for better using the keyboard due to being in a dark environment, or may adjust the brightness of the LED from the first gear to the third gear through two adjustments. Similarly, in the case of other brightness of the LED, the shift may be performed by the above method.

In one possible implementation manner, the user can click a hot key in the keyboard to manually adjust the brightness of the LED of the keyboard.

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

Illustratively, the user may click on key "F3" in the keyboard to turn on the LED brightness of the keyboard, or may click on key "F5" in the keyboard to turn off the LED brightness of the keyboard. Or, the user may also click a key "Fn" in the keyboard to implement switching the LED brightness level from low to high or from high to low (i.e., switching the brightness level), i.e., to implement adjusting the LED brightness of the keyboard.

It should be understood that the above hot keys are only the key "F3", the key "F5" and the key "Fn", and the hot key for adjusting the LED brightness may be other keys, which is not limited in this application.

It should be understood that the number of the steps for adjusting the LED brightness by the number of operations (the number of times of clicking the hot key) shown in the table is only an example, and besides, the user may also perform smooth adjustment on the above-mentioned LED brightness step by one operation (pressing the hot key for a long time), which is not limited in this application.

In this embodiment of the present application, a user may manually set parameters such as the hot key, the preset threshold, the adjustment order, the adjustment time, and the first time period through an application (e.g., a housekeeping application) in the first electronic device.

Fig. 9 is a block diagram of a software structure of a first electronic device to which the embodiment of the present application is applied. The layered architecture divides the software system of the first electronic device 100 into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In the embodiment of the present application, the system may be divided into four layers, namely, an application layer, a system layer, a driver layer, and a hardware layer, and it should be understood that the software structure is exemplified by the first electronic device 100 and the second electronic device 102 being integrally configured.

As shown in fig. 9, the application layer may include a housekeeping application of the first electronic device, and the housekeeping application may be understood as an application installed on the first electronic device, for acquiring the ambient light brightness and generating the adjustment parameters (such as the target brightness or the ambient light brightness and the brightness adjustment strategy) of the brightness of the light emitting device. The system layer comprises a sensor service module and a communication service module, wherein the sensor service module is used for sending ambient light data (namely ambient light brightness) to the housekeeper application, and the communication service module is used for sending brightness adjusting parameters. The driving layer comprises a sensor driver and a communication driving module, wherein the sensor driver is used for sending the ambient light data to the housekeeper application, and the communication driving module is used for transmitting the brightness adjusting parameters to the controller. The hardware layer includes a controller, a System On Chip (SOC), an ambient light sensor, and a light emitting device, wherein the controller is configured to adjust brightness of the light emitting device of the second electronic device, the SOC chip is configured to transmit ambient light data, the ambient light sensor is configured to obtain the ambient light brightness, and the light emitting device is configured to provide brightness.

The brightness adjusting method provided by the present application is further described below with reference to fig. 9 and fig. 10 by taking the first electronic device as a notebook computer, the second electronic device as a keyboard, and the light emitting device as an example.

Fig. 10 is a schematic flowchart of another brightness adjustment method 1000 according to an embodiment of the present application. Referring to fig. 10, the method 1000 may include the steps of:

and S1001, the ambient light sensor acquires ambient light brightness.

It should be understood that, in order to ensure that the automatic adjustment is effective, the ambient light brightness obtained in the embodiment of the present application is the ambient light brightness corresponding to the notebook computer after being turned on for the first time or restarted. The ambient light brightness can be ambient light brightness within a period of time, and the length of the period of time can be preset or manually set by a user, which is not limited by the application.

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

Illustratively, the ambient light sensor may acquire the ambient light level once in 5 s.

And S1002, the ambient light sensor sends the current ambient light brightness to the SOC chip. Correspondingly, the SOC chip receives the current ambient light level from the ambient light sensor.

And S1003, the SOC chip sends the current ambient light brightness to the sensor driver. Correspondingly, the sensor driver receives the current ambient light level from the SOC chip.

S1004, the sensor driver transmits the current ambient light level to the sensor service. Correspondingly, the sensor service receives the current ambient light level from the sensor drive.

S1005, the sensor server sends the current ambient light brightness to the housekeeping application. Correspondingly, the housekeeping application receives the current ambient light level from the sensor service.

S1006, the housekeeping application determines the first information based on the current ambient light brightness.

In a possible implementation manner, the 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 ambient light brightness is located.

For example, the housekeeper application may determine whether the ambient light brightness range in which the ambient light brightness is located matches the current brightness of the LEDs of the keyboard based on a brightness adjustment policy, and determine the LED brightness corresponding to the ambient light brightness range in which the ambient light brightness is located as the target brightness when the ambient light brightness range in which the ambient light brightness is located matches the current brightness of the LEDs of the keyboard.

Or, the housekeeper application may also compare the ambient light brightness with the ambient light brightness received last time after receiving the ambient light brightness, and determine the target brightness from the LED brightness corresponding to the ambient light brightness range where the current ambient light brightness is located when determining that the brightness difference between the current ambient light brightness and the ambient light brightness received last time is greater than the preset threshold.

S1007, the housekeeping application sends first information to the communication service module, the first information being used for the controller to adjust the LED brightness of the keypad. Correspondingly, the communication service module receives first information from the housekeeping application.

Illustratively, the manager application sends the first information to a management instrumentation (WMI) communication service module.

S1008, the communication service module sends the first information to the communication driving module. Correspondingly, the communication driving module receives the first information from the communication service module.

Illustratively, the WMI communication service module transmits the first information to the WMI communication driver module.

S1009, the communication driving module sends the first information to the controller. Correspondingly, the controller receives first information from the communication driving module.

Illustratively, the WMI communication driver module sends the first information to the controller.

S1010, the controller adjusts the brightness of the LED based on the first information.

Illustratively, the brightness of the LED is adjusted to a target brightness.

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

In the present 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 may obtain the target brightness based on the first information and adjust the LED brightness of the keypad to the target brightness. In other words, the target brightness in the present application is determined by the housekeeping application through the analysis calculation, and the controller does not perform the analysis calculation, but only performs the action of adjusting the LED brightness of the keyboard to the target brightness. Therefore, the LED brightness automatic adjustment device has no requirement on the logic calculation capacity of the controller, and the ambient light sensor does not need to be connected with the controller, so that the LED brightness automatic adjustment device also has no requirement on the number of pins of the controller, namely, under the conditions that the logic calculation capacity of the controller is weak and the number of the pins is small, the LED brightness automatic adjustment device still can achieve automatic adjustment on the keyboard, and the cost is effectively reduced.

Optionally, corresponding to the step S1006, the first information may further include the ambient light brightness and an adjustment strategy of LED brightness of the keyboard, where the adjustment strategy of LED brightness of the keyboard includes at least two gears of the LED brightness of the keyboard and an ambient light brightness range corresponding to the at least two gears. The controller receives the first information, and can judge whether the ambient light brightness range of the current ambient light brightness is matched with the current brightness of the LED based on the LED brightness adjusting strategy in the first information. Under the condition that the ambient light brightness range where the current ambient light brightness is located is not matched with the current brightness of the LED, the controller adjusts the brightness of the LED of the keyboard according to target brightness, wherein the target brightness is the LED brightness corresponding to the ambient light brightness range where the current ambient light brightness is located.

Optionally, when the first electronic device and the second electronic device are separately disposed and the second electronic device is an input device of the first electronic device, the communication driving module and the communication service module may support any one of bluetooth technology, WI-FI technology, infrared technology, or the like, which is not limited in this application.

Optionally, the processor may also query the controller for the brightness adjustment function supported by the controller via the corresponding interface before the ambient light sensor obtains the ambient light level.

For example, in the case that the first electronic device is a laptop, the second electronic device is a keyboard, and the light emitting device is an LED, the processor queries the adjustment function of the LED brightness supported by the controller through the BIOS WMI interface as follows:

Optionally, the processor may further implement a mode of automatically adjusting the LED brightness of the keyboard through a corresponding interface.
