In this embodiment, referring to the composition structure of the electronic device provided in fig. 2, the electronic device disclosed in the present application further includes: platform controller hub 40, communication interface 50, and switching device 60.
The platform controller hub 40 is connected to the controller 30.

The communication interface 50 is connected to the controller 30 and can be used at least for connecting to an external input device.

The following will mainly take the communication interface 50 as a USB interface as an example, and the scheme of the present application will be described. In the case that the communication interface 50 is a USB interface, the external input device is correspondingly a USB keyboard, so that the adjustment of the display parameters of the display device 10 is intended to be achieved by means of the external USB keyboard and by multiplexing the USB interface.
The switching device 60 is connected to the controller 30, the display parameter control assembly 20 and the platform controller hub 40.
In the prior art, the communication interface 50 of the electronic device, such as a USB interface, is connected to the platform controller center 40 through the EC to perform USB data interaction with the operating system of the electronic device, but the communication interface 50 is not connected to an information transmission channel between the display parameter control component 20, such as a Scaler, so that, in order to implement multiplexing of the communication interface, such as the USB interface, to adjust the display parameters of the display device 10, in the embodiment of the present application, a switching device 60 is added to the electronic device, and optionally, the switching device 60 is a USB switch (USB switch).
In practice, the USB switch may be integrated inside the EC or separately located outside the EC.
In the case of integrating the USB switch inside the EC, the USB switch is connected to the PCH and the Scaler through different data pins of the EC, as shown in fig. 3, the USB switch integrated inside the EC is connected to the PCH through pins pch_d+ and pch_d-, and is connected to the Scaler through scaler_d+ and scaler_d-. And under the condition that the USB switch is independently arranged outside the EC, the USB switch is connected between the EC and the PCH and Scaler, and the PCH and the Scaler are connected into the USB switch in a parallel mode in any implementation mode.
The added switching device 60, such as a USB switch, is specifically configured to:
1) When the electronic device enters a first mode, i.e. a display mode, a state that the communication interface 50 is electrically connected with the platform controller center 40 is switched to a state that the communication interface 50 is electrically connected with the display parameter control assembly 20, so as to support that in the display mode, display parameter adjustment information such as brightness, contrast and the like is transmitted to the display parameter control assembly 20 through the communication interface 50;
2) When the electronic device enters the second mode, i.e. the host mode, the state in which the communication interface 50 is electrically connected to the display parameter control module 20 is switched to the state in which the communication interface 50 is electrically connected to the platform controller center 40, so as to restore the original functional mode of the communication interface 50, such as a USB interface, and support the interface to perform information interaction with the device system through the PCH.
Correspondingly, the controller 30 is further configured to:
1) In response to detecting the mode switching signal for instructing the electronic device to enter the first mode, the control switching means 60 switches the state in which the communication interface 50 is electrically connected to the platform controller hub 40 to the state in which the communication interface 50 is electrically connected to the display parameter control assembly 20;
2) In response to detecting the mode switching signal for instructing the electronic device to enter the second mode, the control switching means 60 switches the state in which the communication interface 50 is electrically connected to the display parameter control assembly 20 to the state in which the communication interface 50 is electrically connected to the platform controller center 40.
In order to support the display mode of the electronic device, the electronic device further comprises a multimedia data interface for connecting with a multimedia data interface of an external device, which may be, but is not limited to, any of an HDMI interface or a DP interface.
Optionally, in an implementation manner, the mode switching signal for instructing the electronic device to enter the first mode may be a mode switching signal automatically triggered when the electronic device detects that an external device is connected to the electronic device through the multimedia data interface (such as an HDMI interface); the mode switching signal for indicating the electronic device to enter the second mode may be a signal triggered automatically when the electronic device detects that the external device is disconnected from the multimedia data interface. That is, when an external device is detected to be accessed, the electronic device is automatically controlled to enter a display mode to be used as an extended display of the external device, and when the external device is detected to be accessed, the display mode is automatically ended.
Alternatively, in another embodiment, a mode switching component for switching modes of the electronic device between the first mode and the second mode may be additionally disposed at a corresponding position of the body of the electronic device, for example, a mode switching button is disposed on the body of the integrated device. The mode switch component may be operated accordingly to trigger a mode switch signal for instructing the electronic device to enter the first mode or to trigger a mode switch signal for instructing the electronic device to enter the second mode.
Taking the communication interface 50 as a USB interface as an example based on the above-mentioned component structure of the electronic device and the functions of each device in the component structure, when the electronic device enters the host mode, the EC controls the USB switch to switch the USB interface to the PCH, the USB interface provides a normal USB function, and USB data interaction is performed with the device system through the PCH; when a user switches the electronic equipment to a display mode through a mode switching button on the equipment, or the electronic equipment responds to the detection of the access of the external equipment on the multimedia data interface to trigger a mode switching signal, the EC obtains a corresponding mode switching signal and controls the USB switch to switch the USB interface to the scaler, at the moment, the user can trigger a display parameter adjusting signal of the display device of the electronic equipment through operating a corresponding shortcut key on the external keyboard, the EC obtains the signal through the USB interface and transmits display parameter adjusting information corresponding to the signal to a main control chip scaler of the display device through the USB switch (integrated in the EC or independent of the EC), and the scaler adjusts the display parameters of the display device based on the received adjusting information.
Optionally, in an embodiment, the display parameter is brightness, and the brightness of the display device is adjusted by an external keyboard, and in this embodiment, the electronic device further includes a backlight control circuit connected to the display parameter control component 20.
In this embodiment of adjusting the brightness of the display device 10 based on the external keyboard, the controller 30 is specifically configured to:
in the first mode, a key signal provided by an external keyboard connected to the communication interface 50 and used for indicating and adjusting the brightness of the display device 10 is obtained, and brightness adjustment information corresponding to the key signal is transmitted to the display parameter control component 20 through the exchange device 60.
When a user triggers a brightness adjustment signal to the display device 10 by operating a shortcut key on the external keyboard, the EC obtains the signal through the USB interface and transmits brightness adjustment information corresponding to the signal to the scaler through the USB switch.
The luminance adjustment information corresponding to the key signal may be, but not limited to, information for indicating to increase or decrease the luminance of the display device 10 to a certain value, information for indicating to increase or decrease the luminance of the display device 10 by several steps, or the like.
Accordingly, in this embodiment, the display parameter control component 20 is specifically configured to:
generating a pulse width modulation signal of a corresponding target duty ratio according to the received brightness adjustment information; and sends the generated pulse width modulation signal to the backlight control circuit, so that the backlight control circuit changes the output current of the backlight control circuit based on the pulse width modulation signal, and accordingly the brightness of the display device 10 is adjusted.
Specifically, the scaler may generate a PWM (Pulse Width Modulation ) signal of a corresponding target duty ratio according to the received brightness adjustment information, and the backlight control circuit of the display device detects and acquires the signal, adjusts the current according to the signal, increases the brightness of the display device 10 when the current increases, decreases the brightness of the display device 10 when the current decreases, thereby implementing brightness adjustment of the display device 10.
According to the embodiment, the communication interface of the electronic equipment is multiplexed, the switching device for switching the electric connection of the communication interface between the display parameter control component and the platform controller center is additionally arranged in the electronic equipment, so that the display parameters of the display device of the electronic equipment can be adjusted in the display mode, the additional addition of components (such as 2 brightness adjusting buttons) for adjusting the display parameters and a matched equipment internal matching circuit at the integrated machine/television end can be avoided, and the adjustment of the display parameters in the display mode is realized on the basis of changing the hardware design of the electronic equipment as little as possible.
Alternatively, in an embodiment, the adjustment of the display parameters of the display device 10 may be achieved by multiplexing existing components provided on the electronic device itself.
In this embodiment, as shown in fig. 4, the electronic device further includes:
the first functional module 70 and the second functional module 80 are provided in the body of the electronic device and are connected to the controller 30, respectively.
In the second mode, the first functional component is used for performing first functional control on the electronic equipment, and the second functional component is used for performing second functional control on the electronic equipment. The first function control and the second function control are different from the display parameter adjustment control for the display device 10.
The first functional component may be, but not limited to, a power button disposed on the electronic device body and used for performing power control (such as power-on control during power-on, power-off control during power-off, etc.), and the second functional component may be, but not limited to, a mute button disposed on the electronic device body and used for performing mute control on the electronic device.
The present embodiment adjusts display parameters such as brightness/contrast of the display device 10 of the electronic apparatus by multiplexing the first functional component 70 and the second functional component 80.
In this embodiment, the controller 30 is specifically configured to:
in the first mode, the first operation signal of the first functional component 70 or the second operation signal of the second functional component 80 is acquired, and the adjustment information corresponding to the first operation signal or the second operation signal is transmitted to the display parameter control component 20, so that the display parameter control component 20 adjusts the display parameter of the display device 10 according to the adjustment information.
Wherein the first operation signal is used for indicating to raise the display parameter value of the display device 10, and the second operation signal is used for indicating to lower the display parameter value of the display device 10. The first and second operation signals may be, but are not limited to, signals triggered by respectively pressing (short pressing) a power button and a mute button of the electronic apparatus in the display mode.
That is, in the present embodiment, in the first mode, the display parameter value of the display device 10 is raised by multiplexing the first functional module 70, the display parameter value of the display device 10 is lowered by multiplexing the second functional module 80, for example, the display screen brightness or contrast of the all-in-one machine is raised by pressing the power button of the all-in-one machine in the display mode, the display screen brightness or contrast of the all-in-one machine is lowered by pressing the mute button thereof, and the like.
However, the present invention is not limited thereto, and the first operation signal may be used to instruct lowering of the display parameter value of the display device 10, and the second operation signal may be used to raise the display parameter value of the display device 10.
Specifically, taking the controller as the EC, the first functional component 70 and the second functional component 80 as the power button and the mute button of the electronic device respectively as examples, when the EC obtains information for indicating the electronic device to enter the display mode (for example, the EC detects that the external device is accessed through the HDMI interface, or the EC detects a corresponding mode switching signal triggered by a mode switching component on the device), the original functions of the power button and the mute button are controlled to fail, and the functions of the power button and the mute button are respectively enabled to have the function of adjusting the display parameters, otherwise, when the electronic device enters the host mode, the original functions of the power button and the mute button are restored.
In the implementation, the electronic device can be additionally provided with a switching device or a change-over switch and other components for switching the power button/mute button between the original function and the display parameter adjusting function under the control of the EC, so that the original functions of the power button and the mute button are controlled to be invalid in the display mode, and the power button and the mute button are respectively enabled to have the display parameter adjusting function.
Taking the power button as an example, when entering the display mode, the EC control switching device switches the state of the power button electrically connected with the related component in the power management system to the state of the power button electrically connected with the scaler, and when switching from the display mode to the host mode, the EC corresponding control switching device switches the state of the power button electrically connected with the scaler to the state of the power button electrically connected with the related component in the power management system.
The power button is specifically connected with related components and Scalar in the power management system through the EC and the corresponding switching device, and the switching device in the implementation can be integrated inside the EC or independently arranged outside the EC.
Based on this design, in the display mode, taking luminance adjustment as an example, referring to fig. 5, when EC obtains display parameter adjustment information for increasing/decreasing luminance triggered by operating a power button/mute button, adjustment information corresponding to the signal is transmitted to scaler through SMBUS, scaler generates PWM signals of corresponding duty ratio according to the received adjustment information and sends them to a backlight control circuit of display device 10, which increases/decreases own current according to the received PWM signals, thereby achieving increasing/decreasing luminance of display device 10.
Further, optionally, the controller 30 may be further configured to, prior to acquiring the first operation signal of the first functional component 70 or the second operation signal of the second functional component 80:
1) In the first mode, acquiring a third operation signal of the first functional component 70, and controlling the electronic device to enter a first state capable of adjusting a first display parameter of the display device 10 according to the third operation signal;
2) In the first mode, a fourth operation signal of the second functional component 80 is acquired, and the electronic device is controlled to enter a second state capable of adjusting a second display parameter of the display apparatus 10 according to the fourth operation signal.
Wherein, in the first state, the first operation signal and the second operation signal are used for respectively raising and lowering the value of the first display parameter of the display device 10; in the second state, the first and second operation signals are used to raise and lower, respectively, the value of the second display parameter of the display device 10.
Specifically, the third operation signal may be a signal triggered by long pressing of the power button in the display mode, and the fourth operation signal may be a signal triggered by long pressing of the mute button in the display mode.
