Detailed Description

So that the manner in which the features and aspects of the present application can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

Fig. 1 is a schematic structural composition diagram of an electronic device according to an embodiment of the present application, and as shown in fig. 1, the electronic device includes: a first input element 101, an Embedded Controller (EC) 102, and a second input element 103; the EC102 may be connected to the first input device 101 and the second input device 103 through a serial bus, and the input modes of the first input device 101 and the second input device 103 are different.

In this application, the first input element 101 may generate an interrupt signal based on a user's touch on the first input element 101, and then send the interrupt signal to the EC 102.

For example, the first input device 101 may be at least one of a tablet computer, a touch pad, a touch screen, and a touch chip;

in the present application, the EC102 controls the backlight of the second input device 103 to be turned on in response to the input of the first input device 101.

Specifically, the EC102 may receive an interrupt signal sent by the first input device 101, and control the backlight of the second input device 103 to be turned on based on the interrupt signal;

here, the second input member 103 may be a physical keyboard.

When a user inputs data through the first input part 101, the first input part 101 may implement data input through touch input, and the like; when a user inputs data through the second input member 103, the second input member 103 may implement data input through a keyboard input manner.

Specifically, when a user inputs data through the first input element 101, the first input element 101 may detect an interrupt signal generated by a touch of the user, and the first input element 101 sends the interrupt signal to the EC102, and the EC102 may send a Pulse Width Modulation (PWM) signal to the second input element 103 through the serial bus based on the interrupt signal when receiving the interrupt signal, where the PWM signal is used to instruct the backlight of the second input element 103 to be turned on.

In this application, the EC102 may further receive a first input signal sent by the first input element 101 according to the set time length.

For example, the set time period is 15 seconds, 10 seconds, 20 seconds, etc., and the specific set time period may be set by the user.

Specifically, in order to save power consumption, if the backlight of the second input device 103 (e.g., a physical keyboard) is turned on and the second input device 103 is not operated within a predetermined time (e.g., 15 seconds), the backlight of the second input device 103 is automatically turned off. And, by connecting the EC102 to the first input member 101, the EC102 may receive the interrupt signal transmitted from the first input member 101 once every 15 seconds, and in case of receiving the interrupt signal, transmit PWM to the second input member 103 based on the interrupt signal to control the backlight lighting of the second input member 103 by PWM.

According to the electronic equipment provided by the application, the keyboard backlight is directly connected with the EC, and the EC is directly connected with the touch input piece such as a tablet computer, a touch screen or a touch pad, so that the EC can control the keyboard backlight to be turned on by receiving an interrupt signal directly sent by the touch input piece, the control logic of the keyboard backlight can be simplified, and the use experience of a user is improved.

In the present application, after the backlight of the second input device 103 is turned off, the backlight of the second input device 103 may be turned on again by touching any key on the second input device 103. That is, the EC102 may also receive an input signal sent by the second input element 103, the input signal being indicative of data input through the second input element; and transmits PWM to the second input member 103 based on the input signal, wherein the PWM indicates that the backlight of the second input member 103 is turned on.

Since the backlight of the second input device 103 is directly connected to the EC102, the EC102 directly controls the lighting of the backlight of the second input device 103 based on the input signal transmitted from the second input device 103, so that the lighting speed of the backlight of the second input device can be increased, and the lighting efficiency of the backlight can be improved.

In this application, the electronic device may further detect the mouse movement through the system software to turn on the backlight of the second input device 103 again.

Specifically, the electronic device further includes a Platform Controller Hub (PCH) 104 and a Basic Input Output System (BIOS) 105, wherein the PCH104 is connected to the first Input device 101 through a serial bus, and the BIOS 105 is connected to the PCH104 through a serial bus.

When the electronic device re-lights the backlight of the second input element 103 by detecting the mouse movement on the first input element 101, a system command may be issued to the PCH104 through system software, so that the PCH104 captures a mouse event based on the system command, that is, a mouse movement track of the mouse on the first input element 101 is detected to obtain a mouse movement signal, when the PCH104 obtains the mouse movement signal, the PCH104 sends a mouse movement command to the BIOS 105, and the BIOS 105 sends the mouse movement command to the EC102, and when the EC102 receives the mouse movement command sent by the BOIS 105, the EC102 sends PWM to the second input element 103 based on the mouse movement command, so as to control the backlight of the second input element 103 to be lighted according to the PWM.

Through the electronic equipment provided by the application, the awakening mode of the backlight lamp is diversified, and the use experience of a user can be improved.

In this application, when first input device 101 sends an interrupt signal to EC102, it may also send an I2CINT signal to PCH104, so that PCH104 performs related data processing on the touch input of the first input device according to the I2C INT signal.

Fig. 2 is a schematic flow chart of an implementation process of a method for waking up a keyboard backlight by an electronic device in the present application, as shown in fig. 2, the waking up method includes:

step 201, EC controls the backlight lamp of the keyboard to light through PWM;

here, it may be that any key on the keyboard is triggered to control the backlight on the keyboard to be turned on; the backlight lamp of the keyboard can be controlled to be turned on by triggering touch equipment such as a touch screen or a touch pad; the system software can also detect the movement of the mouse to control the lighting of the backlight lamp of the keyboard.

When the keyboard backlight is controlled to be turned on by triggering a touch device such as a touch screen or a touch pad, specifically, the touch device may send an interrupt signal to the EC, and the EC sends PWM to the keyboard based on the interrupt signal, where the PWM indicates that the keyboard backlight is turned on.

When the backlight lamp on the keyboard is controlled to be turned on by triggering any key on the keyboard, specifically, the keyboard sends an input signal to the EC, and the EC sends PWM to the keyboard based on the input signal, wherein the PWM is used for indicating that the backlight lamp of the keyboard is turned on.

When the system software detects mouse movement to control the backlight of the keyboard to be turned on, the system software may specifically send a system command to the PCH, so that the PCH captures a mouse event based on the system command, and when the PCH detects a mouse movement trajectory of the mouse on the first input member 101 to acquire a mouse movement signal, the PCH sends the mouse movement command to the BIOS, and then the BIOS sends the mouse movement command to the EC, and the EC sends PWM to the keyboard based on the mouse movement command, where the PWM is used to indicate that the backlight of the keyboard is turned on.

Step 202, after the backlight lamp of the keyboard is lighted up, the EC detects the INT pin connected with the touch screen or the touch pad once every 15 seconds;

here, it is mainly detected whether the INT pin of the EC connected to the touch screen or the touch pad generates an interrupt signal.

Step 203, judging whether the INT pin has an interrupt signal;

here, when a user performs data input by touching the touch screen or the touch pad, the INT pin generates an interrupt signal due to the user touching; otherwise, the INT pin does not generate an interrupt signal.

When the judgment result represents that the INT pin generates an interrupt signal, executing step 204; when the determination result indicates that the INT pin does not generate the interrupt signal, performing step 205;

step 204, the EC controls the backlight lamp of the keyboard to be lightened, and the time is counted again for 15 seconds;

specifically, an interrupt signal is sent to the EC by the touch screen or the touch pad, and the EC sends a PWM signal to the keyboard based on the interrupt signal when receiving the interrupt signal, wherein the PWM signal is used for indicating that a backlight of the keyboard is turned on.

Step 205, continue the current timing operation.

Here, continuing the current time counting operation may refer to restarting the time counting for 15 seconds from the current time, or continuing the time counting until the detection time length reaches 15 seconds when the time length between the time of performing step 202 and the current time does not reach 15 seconds. And re-executing the steps 202 to 205 when the detection time reaches 15 seconds.

By the aid of the electronic equipment, the wake-up mode of the keyboard backlight lamp can be diversified, control logic of the keyboard backlight lamp can be simplified, and use experience of a user is improved.
