The control instruction may be generated, for example, in accordance with an input operation of a user for the electronic apparatus, or in response to a change in a connection relationship of the electronic apparatus with an external apparatus. For example, the electronic device changes from being connected to a particular type of external device to being disconnected from the particular type of external device.

According to the embodiment of the disclosure, the power supply component supplies power to the output component in the first state so as to ensure that the output component outputs the multimedia content, and signals can be transmitted between the transmission component and the external device. In the second state, the power supply component does not supply power to the output component, the output component may not output multimedia content, for example, and a signal can be transmitted between the transmission component and the external device. In the second state, for example, only the power supply component and the transmission component in the power supply component in the electronic device may remain in operation, while the other components in the electronic device may stop operating. The power supply component may be a component for supplying power to an external device connected to the electronic device.

In particular, the electronic device may be, for example, a display, the first state may be that the display outputs image data, and the second state may be, for example, that an output component of the display is not operating, and the display is blank. According to the embodiment of the present disclosure, whether the display is in the first state or the second state, a signal can be transmitted between the display and an external device, wherein the external device is electrically connected with the display.

According to an embodiment of the present disclosure, in the second state, transmitting a signal between the transmission component and the external device includes: the power supply assembly transmits electric energy to the external equipment through the transmission assembly.

According to the embodiment of the disclosure, the operating state of the electronic device may further include a third state in which the power supply component does not supply power to the output component and the transmission component cannot transmit a signal with the external device. The third state may be, for example, the electronic device being completely powered off.

According to an embodiment of the present disclosure, the electronic device may further include an input component. The input assembly is used for receiving input operation of a user and generating an operation signal according to the input operation, wherein the transmission of the signal between the transmission assembly and the external equipment comprises the following steps: the transmission component transmits an operation signal to an external device.

According to an embodiment of the present disclosure, the method may control an input component of an external device connected to the electronic device by operating the input component of the electronic device.

The input component may be, for example, a button, a keyboard, etc. For example, a user may press a power key of the display, the display generates an operation signal in response to an operation of the user pressing the power key, and may transmit the operation signal to the external device, so that the external device controls its operating state according to the operation signal. For example, the power-on state may be changed to the power-off state.

According to the embodiment of the present disclosure, the external device may determine the control instruction indicated by the operation signal from the electronic device according to its own setting to change its own state according to the control instruction.

According to embodiments of the present disclosure, an input component, which may be, for example, a display, may be used on behalf of an input component of an external device.

According to an embodiment of the present disclosure, the input operation may include a first operation, and the input component generates a first operation signal according to the first operation. The first operation signal is used to switch the external device from a fourth state to a fifth state, wherein the power consumption of the fourth state is higher than the power consumption of the fifth state, and the control electronic device is switched from the first state or the second state to the third state.

According to an embodiment of the present disclosure, the first operation may be, for example, a combined key behavior, and the combined key behavior may be a behavior of operating at least two keys. Specifically, for example, the power key and the volume up key may be simultaneously pressed. According to the embodiment of the disclosure, for example, when the power key and the volume increase key are pressed simultaneously, the generated first operation signal may control the external device to switch from the power-on state to the power-off state, and in a case that the electronic device detects that the external device has switched to the power-off state, the control component of the electronic device controls the external device to switch from the first state or the second state to the power-off state.

According to the embodiment of the disclosure, the electronic device can control the external device to switch to the low-power-consumption working state through the first operation, and the electronic device can switch the working state of the electronic device along with the change of the working state of the external device, so that the technical effect of controlling the two devices through the operation of the electronic device is achieved.

According to the embodiment of the disclosure, the input operation comprises a second operation, the input component generates a second operation signal according to the second operation, and the control component switches the electronic device from the first state to the second state according to the second operation signal.

The second operation may be, for example, the user pressing a certain key. When the specific key is pressed, the key generates a second operation signal and sends the second operation signal to the control component, so that the control component switches the electronic equipment from the first state to the second state according to the second operation signal.

According to an embodiment of the present disclosure, the electronic device may include, for example, a first mode and a second mode in the first state. In the first mode, if the second operation is received, the electronic device may be switched from the first state to the third state. In the second mode, if the second operation is received, the electronic device may be switched from the first state to the second state.

According to an embodiment of the present disclosure, the control component switching the electronic device from the first state to the second state according to the second operation signal includes: the control component determines the attribute information of the external device, and under the condition that the attribute information is determined to be the same as the preset attribute information, the electronic device is switched from the first state to the second state according to the second operation signal.

According to an embodiment of the present disclosure, the attribute information may be, for example, a device type or a device identification of the external device. Specifically, for example, when the protocol to which the interface to which the external device is connected to the transmission component belongs is a specific protocol, the electronic device may be switched from the first state to the second state according to the second operation signal. For another example, when the identifier of the external device is one of the preset identifiers, the electronic device may be switched from the first state to the second state according to the second operation signal.

According to an embodiment of the present disclosure, the electronic device may further include an indication component for determining and displaying an indication signal according to the operating state information of the electronic device in the first mode, and determining and displaying an indication signal according to the operating state information of the external device in the second mode. Wherein, in the second mode, transmitting signals between the transmission component and the external device comprises: the transmission component receives the working state information from the external equipment and sends the working state information to the indication component.

According to an embodiment of the present disclosure, the indication component may be, for example, an indicator light.

According to the embodiment of the disclosure, the electronic device can display the working state of the external device through the indicating component in the second mode, so that the technical effect of determining the working state of the external device by looking at the indicating component is achieved.

Hereinafter, the operation principle of the display according to the embodiment of the present disclosure will be described by taking an example in which the display is connected to an external device through a type C interface.

According to an embodiment of the present disclosure, a display may include, for example, two modes of operation, a first mode and a second mode. The user may set the operating mode of the display in a menu of the display. When the display is in the second mode, the USB C interface is always in the open state no matter the display is powered on or powered off. When detecting that the first external equipment is inserted into the USB C interface, judging whether the attribute information of the first external equipment is the same as the preset attribute information. If the preset attribute information is determined to be the same, other interfaces are not automatically scanned unless the user manually switches the interface from which the video output by the display comes. And if the video output by the display comes from the first external equipment, reading the working state of the external equipment. The working state of the display and the state of the indicator light of the display are consistent with the external equipment. If the currently displayed video is from other interfaces than the USB C interface, the adaptation of the second external device connected to the other interfaces is displayed, and the operation mode of the display may be the first mode at this time. When a plurality of external devices are connected with the display at the same time, the display can be switched to the display interface at will, and once the display is switched to the USB C interface, the working states of the external devices connected with the USB C interface are consistent. When the external equipment of the USB C interface is different from the preset attribute information or the external equipment of the USB C interface is not connected with the equipment, the display automatically scans each interface, and once the external equipment of other interfaces exists, the working mode is the first mode. When one of the external devices is in a sleep or power-off state, the external device is automatically switched to the other external device.

According to the embodiment of the disclosure, in the second mode, the working state of the display is consistent with that of the external device, and the indicator light of the display at least displays the working state of the external device. The display power key can replace a power key of the external device, the display power key can be pressed to enable the external device to be started, sleep, dormant, powered off, turned off and the like, and the working state of the display and the state of the LED lamp completely follow the state of the external device. For example, when the external equipment works, the display displays normally, and the indicator light is green and keeps supplying power to the outside. When the external equipment sleeps, the display sleeps, and the pilot lamp is green lamp scintillation state, keeps supplying to the external. When the external equipment is in a dormant state or is turned off, the display is turned off, the indicator lamp is turned off, and the external power supply is kept. After long pressing the display combination button, external equipment closes, and the display closes, and the pilot lamp is closed, no longer supplies power to the outside.

According to the embodiment of the disclosure, in the first mode, the display power key can only control the display, and does not affect the external device. For example, the display can display normally, and the indicator light is green and keeps supplying power to the outside. The display sleeps, and the pilot lamp is the orange lamp, keeps external power supply. The display is closed and no power is supplied to the outside.

Specifically, the following describes an embodiment of the display according to the present disclosure, taking an example in which the display is set to the second mode, and the USB C interface of the display is connected to an external device that is the same as the preset attribute information.

If the display and the external equipment are both in the power-off state, the display is turned on when a power key of the display is pressed, the indicator light of the display turns green, and the external equipment is turned on and works normally.

In this scenario, the display is in the off state, i.e., the output component of the display is not operating, the power supply component does not supply power to the output component, and the display may supply power to the external device, at which time the display is in the second state. When the display is in the second state, a power key of the display is pressed, the display can be switched to the first state, namely the output assembly outputs image data, and the power supply assembly supplies power to the output assembly.

If the display is turned off and the external equipment runs, the display can be turned on by pressing the power key of the display, the indicator light of the display is green, and the working state of the external equipment is not changed.

In this scenario, the display may still be switched from the second state to the first state.

If both the display and the external device are turned on, and the power key of the external device is set to "not change state". If the display power key is pressed, neither the external device nor the display changes state.

In this scenario, the display is in a first state, and the display may transmit an operation signal to an external device. If the power key of the display is pressed, the display sends the operation signal to the external device, so that the external device changes the state of the external device according to the setting attribute of the power key of the external device. In the case where the setting attribute is "not to change the state", the external device does not change its own state, and the display does not change its own state.

If both the display and the external device are on, and the power key of the external device is set to "sleep". If the power key of the display is pressed, the external equipment sleeps, the indicator light of the external equipment is a breathing light, the display sleeps, and the indicator light of the display flickers in a green light mode. For example, the power key of the display is pressed again, the external equipment is activated, and the external equipment works normally; the display normally displays, and the indicator light of the display turns green.

In this scenario, the display is still in the first state, and the display can still transmit the operation signal to the external device. The external device changes its own operating state according to the operation signal, and the operating state of the display is kept consistent with that of the external device.

If both the display and the external device are turned on, and the power key of the external device is set to "sleep". If the power key of the display is pressed, the external equipment is dormant, and the indicator lamp of the external equipment is turned off; the display is dormant, the display indicator lamp is turned off, and the power supply for the external equipment is still reserved.

If the display and the external equipment are both started, and the power key of the external equipment is set to be 'off', the external equipment is turned off and the indicator lamp of the external equipment is turned off when the power key of the display is pressed. The display is turned off and the lights are turned off, still maintaining power to the external device.

In this scenario, the display is in a first state, and the display may transmit an operation signal to an external device. When the power key of the display is pressed, the external device changes the self state to 'off' according to the operation signal from the display, and the display is switched from the first state to the second state.

If both the display and the external device are on, and the power key of the external device is set to "turn off the display". If the power key of the display is pressed, the external equipment is powered off, and the indicator lamp of the external equipment is turned off. The display is then turned off and the display indicator lights go off, still leaving the external device powered.

If the display is connected with the external equipment in the sleeping state when the display sleeps to display the orange lamp, the display sleeps after the connection, and the display flickers at a green lamp. Then if the connection between the display and the external device is broken, the display still sleeps to display the orange light.

When the display is in a sleep display orange lamp state, if the external equipment in a dormant or power-off state is connected, the display is turned off after the connection, the indicator lamp of the display is turned off, and the external equipment is still kept powered; the connection between the display and the external device is then broken and the display still sleeps to show the orange light.

As described above, the display still supplies power to the external device after being turned off, and if the external device is in a dormant state or a turned-off state at this time, the external device can still be turned on by pressing the power key of the external device without a battery or an external power supply.

If the power supply and menu keys of the display are pressed for more than 3s for a long time, the external equipment is turned off, the display is turned off, the lamp is turned off, and the display is not powered on after being turned off. If the external equipment is in a dormant state or a power-off state at the moment, and the battery and the external power supply do not exist, the external equipment cannot be started by pressing the power key of the external equipment.

In this scenario, the display may switch from the first state or the second state to the third state in response to a user pressing a combination key press action of the "power" and "menu" keys. And the external device is switched from the fourth state to the fifth state, wherein the power consumption of the fourth state is higher than the power consumption of the fifth state.

Specifically, the following describes an embodiment of the display according to the present disclosure, taking as an example that the display is set to the second mode, and the USB C interface of the display is connected to one first external device that is the same as the preset attribute information, and the other interface of the display is connected to a second external device such as HDMI/VGA/DP.

The power-on instant may, for example, prioritize the display of image data from the first external device. The display's key behavior changes as the source of the image data changes. If the image data is from the first external device, the keying behavior of the display is automatically switched to the second mode, and if the image data is from the second external device, the keying behavior of the display is automatically switched to the first mode.

If the display and the first external equipment are both in the power-off state, the display is turned on and the indicator light of the display turns green when the power key of the display is pressed. And the first external equipment is started and works normally. The display preferentially displays image data from the first external device.

If the display is closed, when the first external equipment and the second external equipment operate, pressing a power key of the display, starting the display, and preferentially displaying the image data from the first external equipment by using a green light of a display indicator lamp; the operating state of the first external device is not changed.

If the display, the first external device and the second external device are all started or sleep, the display can switch the source of the image data at will. When the display is switched to the first external device, the working state of the display is consistent with that of the first external device. The display indicator light completely follows the status of the first external device.
