Background technique

For current smart devices, the signal processing voltage for display and touch functions is usually controlled by the same chip, and because the display function consumes more power, the display and touch functions are powered by a dedicated power supply circuit. However, the power consumption of the dedicated power supply circuit itself is very high, so in scenarios where only the touch function needs to be used, such as turning off the screen for a long time and clicking the screen to turn it on, the power consumption of the electronic device is too high, which shortens the standby time of the device.

Detailed ways

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It is understood that the specific embodiments described herein are only used to explain the related applications, rather than to limit the applications. It should also be noted that, for ease of description, only the parts related to the related applications are shown in the drawings.

With the development of technology, the solution of combining display and touch control in one chip has gradually replaced the solution of using separate chips for display and touch control. However, in the use of smart electronic devices such as smart watches, there are not only scenarios where display and touch control are used at the same time, but also scenarios where only touch control is used, such as clicking to light up the screen.

In a smart electronic device, as the battery power is consumed, the battery output voltage will gradually decrease; at the same time, the voltage of different external electronic devices is also different. In the usual design, there will be a universal power control chip that converts the battery voltage into different voltages and provides them to various electronic devices. For some external electronic devices with high power consumption, such as screens, the universal power control chip cannot provide sufficient output capacity, so a separate power supply circuit needs to be designed.

The touch screen includes display and touch functions. Usually, one or two chips are needed to process the display and touch data; therefore, the chip needs a voltage to maintain the chip's data processing; at the same time, a signal processing voltage is also required to realize the display and touch functions. For the touch function, the signal processing voltage is used to continuously scan the capacitors in the screen, obtain the change in capacitance, and convert it into a touch signal; and for the display function, the signal processing voltage is used to continuously light up the LED in the screen, or to continuously change the polarization of the liquid crystal while powering the backlight to make it emit light. Therefore, the touch screen usually requires two voltages for power supply, namely the chip processing voltage provided to the chip operation and the signal processing voltage for providing touch signal capture and display signal performance.

FIG1 is a schematic diagram of an existing power supply scheme. FIG1 is a power supply scheme when the display function and the touch function are each controlled by a chip. It can be seen that when the display function and the touch function are each controlled by a chip, the chip processes the power. The voltage of the touch signal is also provided by the universal power processing chip. The signal processing voltage of the display is provided by the dedicated circuit of the screen-specific power control chip; in addition, the battery can provide the power used by the electronic device, and other voltages used by other external electronic devices can also be controlled by the universal power control chip. The main chip is the core component of the electronic device and the brain that controls the operation of the electronic device.

FIG2 is a schematic diagram of an existing power supply scheme 2. FIG2 is a power supply scheme when the display function and the touch function share a chip. It can be seen that when the display function and the touch function share a chip, the chip processing voltage is provided by a general power processing chip. The signal processing voltage is provided by a dedicated circuit.

At present, the solution of integrating display and touch control into the same chip has gradually replaced the solution of integrating display and touch control into one chip. In the solution of integrating display and touch control into the same chip, it is assumed that display and touch control are used simultaneously, that is, when the screen is turned off, the touch control is also turned off at the same time. This is a very common solution in mobile phones, but it does not conform to the usage scenarios of smart watches. For smart watches, there are usually scenarios where the screen is turned off for a long time and the screen is turned on by clicking on it. In this scenario, the display function of the touch screen is turned off, but the touch function still needs to be turned on. The display is very power-consuming, and the output capacity of the general power control chip is insufficient, so a special circuit is required to supply power, and this special power supply circuit itself has very high power consumption. Therefore, in the prior art, for scenarios where only the touch function needs to be used, such as turning off the screen for a long time and clicking on the screen to turn on the screen, there is a problem that the power consumption of the electronic device is still very high, thereby shortening the standby time of the electronic device.

In order to solve the problems existing in the power supply method in the above scheme, the embodiment of the present application provides a power supply method, an electronic device and a chip. The power supply method is applied to an electronic device with a display screen. When the electronic device receives a first touch operation through the display screen in the first mode, it switches from the first mode to the second mode in response to the first touch operation; wherein the first mode is a mode in which the signal processing voltage of the touch function is obtained through the first power supply circuit connected to the first chip; and the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through the second power supply circuit connected to the second chip. It can effectively reduce power consumption and improve the standby time of the electronic device.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The present application embodiment provides a power supply method, which is applied to an electronic device with a display screen. FIG3 is a schematic diagram of a first implementation flow of the power supply method proposed in the present application embodiment. As shown in FIG3 , the power supply method for the electronic device may include the following steps:

Step 101. In the first mode, when a first touch operation is received through the display screen, the first mode is switched to the second mode in response to the first touch operation; wherein the first mode is a mode for obtaining a signal processing voltage for a touch function through a first power supply circuit connected to a first chip; and the second mode is a mode for obtaining a signal processing voltage for a display function and a touch function through a second power supply circuit connected to a second chip.

In an embodiment of the present application, the electronic device can, in the first mode, switch from the first mode to the second mode in response to the first touch operation when receiving the first touch operation through the display screen; wherein the first mode is a mode in which the signal processing voltage of the touch function is obtained through a first power supply circuit connected to the first chip; and the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through a second power supply circuit connected to the second chip.

It should be noted that, in the embodiments of the present application, the electronic device can be any electronic device with communication and storage functions, such as: tablet computers, mobile phones, e-readers, remote controls, personal computers (PC), laptop computers, vehicle-mounted electronic devices, network televisions, wearable electronic devices, personal digital assistants (PDA), portable media players (Pportable Media Player, PMP), navigation devices and other electronic devices.

Furthermore, in an embodiment of the present application, the display screen may be a touch screen supporting touch operations, and the touch screen is an inductive liquid crystal display device that can receive input signals such as contacts.

It should be noted that, in the embodiment of the present application, the power consumption of the first power supply circuit is less than the power consumption of the second power supply circuit.

It should be noted that, in the embodiment of the present application, the first mode is a mode in which the display function is turned off and the touch function is turned on.

That is to say, in the embodiment of the present application, the first mode is the click-to-light-screen mode. In the first mode, the display The screen does not display any content and is black. Only when the display screen receives the first touch operation, the electronic device will respond to the first touch operation and light up the screen.

Exemplarily, in an embodiment of the present application, the electronic device is a smart watch, and Figure 4 is a schematic diagram of the click-to-light-screen mode. As shown in Figure 4, during the day, when the user is not using the smart watch, the smart watch is in the first mode. In the first mode, the display screen of the smart watch is black and does not display any content. When the smart watch receives a touch operation (first touch operation) through the display screen, the screen lights up and displays relevant content, thereby entering the second mode.

It should be noted that, in the embodiment of the present application, in the first mode, the first power supply circuit is in the on state; and the second power supply circuit is in the off state.

Exemplarily, in an embodiment of the present application, Figure 5 is a schematic diagram of the power supply method in the first mode. As shown in Figure 5, the power supply circuit of the electronic device includes a battery, a main chip, a first chip, a second chip and other external electronic devices, etc.; wherein the battery can provide electrical energy; the chip processing voltage is the voltage provided to each chip, which is used for calculations inside the chip; the first power supply circuit is connected to the first chip, and the second power supply circuit is connected to the second chip, and the first power supply circuit and the second power supply circuit both participate in the control of the signal processing voltage of the display function and the touch function; other voltages used by other external electronic devices can also be controlled by the first chip; it can be seen that when the electronic device is in the first mode, the first power supply circuit is in the on state and the second power supply circuit is in the off state. Due to the low power consumption of the first power supply circuit, its power supply capacity is insufficient to support the consumption of the display function. In this state, only the touch function is supported, and the display function is turned off, effectively reducing the overall power consumption of the electronic device.

In addition, as shown in FIG. 5 , it can be seen that in the first mode, the chip processing voltage for providing the internal computing function of the chip is provided by the chip power supply circuit connected to the first chip.

It can be understood that in the embodiments of the present application, the first touch operation refers to an operation in which, in the first mode, the display screen of the electronic device is touched to light up the display screen of the electronic device and enter the second mode; for example, the first touch operation can be a click operation, and when the electronic device receives the click operation through the display screen, it can switch from the first mode to the second mode.

Further, in an embodiment of the present application, the second mode is a mode in which the display function and the touch function are turned on simultaneously.

That is to say, in the embodiment of the present application, the second mode is the normal mode. In the second mode, the display function and the touch function of the display screen are normally turned on, that is, the display content and the touch operation are supported.

It should be noted that, in the embodiment of the present application, in the second mode, the first power supply circuit is in the off state; and the second power supply circuit is in the on state.

Exemplarily, in an embodiment of the present application, Figure 6 is a schematic diagram of the power supply method in the second mode. As shown in Figure 6, in the second mode, the first power supply circuit is turned off and the second power supply circuit is turned on. The second power supply circuit is used to provide signal processing voltage for the display function and the touch function. Since the second power supply circuit has a strong power supply capacity and can support the consumption of the display function, in the second mode, by turning on the second power supply circuit, the use of the display function and the touch function can be supported at the same time.

It should be noted that, in the embodiment of the present application, in the second mode, the overall power consumption of the electronic device is relatively large, which is greater than the power consumption of the electronic device in the first mode.

Further, in an embodiment of the present application, as shown in FIG. 6 , it can be seen that in the second mode, the chip processing voltage for providing the internal computing function of the chip is provided by a chip power supply circuit connected to the first chip.

That is, in the embodiment of the present application, in the first mode or the second mode, the chip processing voltage is obtained through the chip power supply circuit connected to the first chip.

It can be seen that in an embodiment of the present application, in a scenario where the display function is not used and only the touch function is used, the electronic device can turn off the second power supply circuit that can support the display function but has higher power consumption, and use the first power supply circuit for power supply, thereby greatly reducing the power consumption of the electronic device in this scenario and extending the standby time of the electronic device.

Further, in an embodiment of the present application, FIG. 7 is a second schematic diagram of the implementation flow of the power supply method proposed in the embodiment of the present application. As shown in FIG. 7 , the power supply method may further include the following steps:

Step 201: In the second mode, display processing is performed through the display screen, and when a second touch is received through the display screen During the operation, in response to the second touch operation, a process corresponding to the second touch operation is executed.

In an embodiment of the present application, the electronic device may also perform display processing through the display screen in the second mode, and when receiving a second touch operation through the display screen, execute processing corresponding to the second touch operation in response to the second touch operation.

That is to say, in an embodiment of the present application, when the electronic device is in the second mode, it can support both the display function and the touch function; when the electronic device is in the second mode, the display screen is lit and can display relevant content. At the same time, the display screen can normally receive any touch operation, and the electronic device can respond to and process any touch operation received.

It can be understood that, in the embodiment of the present application, the second touch operation refers to any touch operation that can be received on the display screen when the electronic device is in the second mode.

Exemplarily, in an embodiment of the present application, Figure 8 is a schematic diagram 1 of the second mode. As shown in Figure 8, in the second mode, content is displayed on the display screen of the electronic device, and an upward swipe operation (second touch operation) is received through the display screen. The electronic device responds to the upward swipe operation, and the content on the display screen can slide upward to display (processing corresponding to the second touch operation).

Exemplarily, in an embodiment of the present application, Figure 9 is a second schematic diagram of the second mode. As shown in Figure 9, in the second mode, content is displayed on the display screen of the electronic device, and a right swipe operation (second touch operation) is received through the display screen. The electronic device responds to the right swipe operation, and the content on the display screen can be displayed by sliding to the right (processing corresponding to the second touch operation).

Exemplarily, in an embodiment of the present application, Figure 10 is a third schematic diagram of the second mode. As shown in Figure 10, in the second mode, content is displayed on the display screen of the electronic device, for example, multiple software (Application, APP) are displayed, including APP1 and APP2; a click operation (second touch operation) corresponding to APP1 is received through the display screen, so that the electronic device responds to the click operation corresponding to APP1 and displays the page content of entering APP1 on the display screen; further, the display screen can continue to receive any second touch operation based on the state of displaying the page content of APP1, and the electronic device can continue to respond and make corresponding processing.

Furthermore, in the embodiments of the present application, in addition to the first mode and the second mode, a third mode may also be included.

FIG. 11 is a schematic diagram of a third implementation flow of the power supply method proposed in an embodiment of the present application. As shown in FIG. 11 , the power supply method for an electronic device may further include the following steps:

Step 301: In the third mode, when a wake-up operation is received, in response to the wake-up operation, switching from the third mode to the second mode; wherein the third mode is a mode for shutting down the first power supply circuit and the second power supply circuit.

In an embodiment of the present application, the electronic device can also switch from the third mode to the second mode in response to a wake-up operation when receiving a wake-up operation in the third mode; wherein the third mode is a mode in which the first power supply circuit and the second power supply circuit are turned off.

It should be noted that, in the embodiment of the present application, the third mode is a mode in which the display function and the touch function are turned off simultaneously.

That is to say, in the embodiment of the present application, the third mode is the off mode of the electronic device. In the third mode, the electronic device is in an off state and supports neither the touch function nor the display function.

Furthermore, in an embodiment of the present application, an electronic device in the third mode can be awakened by a preset wake-up method; for example, when the electronic device receives a preset wake-up operation, it can exit the third mode and enter the second mode; wherein the specific method of the wake-up operation is not limited in this application.

It should be noted that, in the embodiment of the present application, in the third mode, the first power supply circuit, the second power supply circuit and the chip power supply circuit are all in a closed state.

Illustratively, in an embodiment of the present application, FIG12 is a schematic diagram of a power supply method in a third mode. As shown in FIG12 , in the third mode, the first power supply circuit, the second power supply circuit and the chip power supply circuit are all in a closed state.

It is understood that in the embodiment of the present application, in the third mode, the display screen is not powered, and the display function and The touch function is turned off at the same time. At this time, the electronic device cannot receive any touch operation through the display screen, that is, the touch is unresponsive; at the same time, the display screen is also black and no content is displayed.

Further, in an embodiment of the present application, in the third mode, when the electronic device receives a wake-up operation, it can switch from the third mode to the second mode in response to the wake-up operation.

Exemplarily, in an embodiment of the present application, the wake-up method is to wake up the electronic device by pressing a button; Figure 13 is a schematic diagram of the wake-up operation. As shown in Figure 13, before the wake-up operation is performed, the display screen of the electronic device is in a power-off state, does not display any content, and does not support touch operations; when the electronic device receives a button operation (wake-up operation), the electronic device is awakened, the display screen exits the off mode, and the display function and the touch function are turned on. For example, after exiting the off mode, the power-on screen "welcome" is displayed, indicating that the second mode has been entered, and the touch function and the display function can be used normally.

Furthermore, in an embodiment of the present application, the electronic device may also receive a shutdown operation, and switch from the first mode to the third mode, or from the second mode to the third mode, in response to the shutdown operation.

In summary, the present application designs a multi-channel power supply solution that can meet the different power supply requirements of the display screen in various scenarios, while reducing the power consumption of the entire device and extending the standby time.

The embodiment of the present application provides a power supply method, which is applied to an electronic device with a display screen; when the electronic device receives a first touch operation through the display screen in the first mode, it switches from the first mode to the second mode in response to the first touch operation; wherein the first mode is a mode in which the signal processing voltage of the touch function is obtained through the first power supply circuit connected to the first chip; and the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through the second power supply circuit connected to the second chip. It can be seen that in the present application, when the electronic device is in the first mode, that is, when only the touch function needs to be used, the signal processing voltage of the touch function can be obtained through the first power supply circuit, so that the use of the touch function can be supported while maintaining low power consumption; and when the electronic device is in the second mode, that is, when the display function and the touch function need to be used at the same time, the signal processing voltage of the display function and the touch function is obtained through the second power supply circuit to support the use of the display function and the touch function at the same time, so that the power consumption of the electronic device can be effectively reduced and the standby time of the electronic device can be improved.

Based on the above embodiment, in another embodiment of the present application, a power supply method is exemplarily provided, which is applied to an electronic device with a display screen. FIG. 14 is a fourth schematic diagram of an implementation flow of the power supply method proposed in the embodiment of the present application. As shown in FIG. 14, the power supply method for the electronic device may include the following steps:

Step 401: In a first mode, a first touch operation is received through a display screen, and in response to the first touch operation, the first mode is switched to a second mode.

In an embodiment of the present application, the electronic device may receive a first touch operation through a display screen in a first mode, and switch from the first mode to a second mode in response to the first touch operation.

It should be noted that, in an embodiment of the present application, the first mode is a mode in which the signal processing voltage of the touch function is obtained through a first power supply circuit connected to the first chip; the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through a second power supply circuit connected to the second chip.

Further, in an embodiment of the present application, the power consumption of the first power supply circuit is less than the power consumption of the second power supply circuit.

It should be noted that, in the embodiment of the present application, the first mode is a mode in which the display function is turned off and the touch function is turned on.

That is to say, in an embodiment of the present application, the first mode is the click-to-light-screen mode. In the first mode, the display screen does not display any content. Only when the display screen receives a first touch operation will the electronic device respond to the first touch operation and light up the screen.

Exemplarily, in an embodiment of the present application, the electronic device is a smart watch, as shown in FIG4 . During the day, when the user is not using the smart watch, the smart watch is in a first mode. In the first mode, the display screen of the smart watch is black and does not display any content. When the smart watch receives a touch operation (first touch operation) through the display screen, the screen lights up and displays relevant content, thereby entering the second mode.

It should be noted that, in the embodiment of the present application, in the first mode, the first power supply circuit is in the on state; The second power supply circuit is in a closed state.

Among them, the power supply method of the electronic device in the first mode is shown in Figure 5, and the power supply circuit of the electronic device includes a battery, a main chip, a first chip, a second chip and other external electronic devices, etc.; wherein the battery can provide electrical energy; the chip processing voltage is the voltage provided to each chip, which is used for calculations inside the chip; the first power supply circuit is connected to the first chip, and the second power supply circuit is connected to the second chip, and the first power supply circuit and the second power supply circuit both participate in the control of the signal processing voltage of the display function and the touch function; other voltages used by other external electronic devices can also be controlled by the first chip; it can be seen that when the electronic device is in the first mode, the first power supply circuit is in the on state and the second power supply circuit is in the off state. Due to the low power consumption of the first power supply circuit, its power supply capacity is insufficient to support the consumption of the display function. In this state, only the touch function is supported, and the display function is turned off, effectively reducing the overall power consumption of the electronic device.

Furthermore, in an embodiment of the present application, in the first mode of the electronic device, a chip processing voltage for providing a computing function inside the chip is provided by a chip power supply circuit connected to the first chip.

It can be understood that in the embodiments of the present application, the first touch operation refers to an operation in which, in the first mode, the display screen of the electronic device is touched to light up the display screen of the electronic device and enter the second mode; for example, the first touch operation can be a click operation, and when the electronic device receives the click operation through the display screen, it can switch from the first mode to the second mode.

Further, in an embodiment of the present application, the second mode is a mode in which the display function and the touch function are turned on simultaneously.

That is to say, in the embodiment of the present application, the second mode is the normal mode. In the second mode, the display function and the touch function of the display screen are normally turned on, that is, the display content and the touch operation are supported.

It should be noted that, in the embodiment of the present application, in the second mode, the first power supply circuit is in the off state; and the second power supply circuit is in the on state.

Illustratively, in an embodiment of the present application, the power supply method of the electronic device in the second mode can be as shown in Figure 6. In the second mode, the electronic device can turn off the first power supply circuit, turn on the second power supply circuit, and use the second power supply circuit to provide signal processing voltage for the display function and the touch function. Since the second power supply circuit has a strong power supply capacity and can support the consumption of the display function, in the second mode, by turning on the second power supply circuit, the use of the display function and the touch function can be supported at the same time.

It should be noted that, in the embodiment of the present application, in the second mode, the overall power consumption of the electronic device is relatively large, which is greater than the power consumption of the electronic device in the first mode.

Further, in an embodiment of the present application, in the second mode, a chip processing voltage for providing a computing function inside the chip is provided by a chip power supply circuit connected to the first chip.

That is, in the embodiment of the present application, in the first mode or the second mode, the chip processing voltage is obtained through the chip power supply circuit connected to the first chip.

It can be understood that in an embodiment of the present application, in a scenario where the display function is not used and only the touch function is used, the electronic device can turn off the second power supply circuit that can support the display function but has higher power consumption, and use the first power supply circuit for power supply, thereby greatly reducing the power consumption of the electronic device in this scenario and extending the standby time of the electronic device.

Step 402: Perform display processing through the display screen, and when a second touch operation is received through the display screen, execute processing corresponding to the second touch operation in response to the second touch operation.

In an embodiment of the present application, when the electronic device is in a first mode, when a first touch operation is received through the display screen, in response to the first touch operation, after switching from the first mode to the second mode, display processing can be performed through the display screen, and when a second touch operation is received through the display screen, in response to the second touch operation, processing corresponding to the second touch operation is performed.

That is to say, in an embodiment of the present application, when the electronic device is in the second mode, it can support both the display function and the touch function; at this time, the display screen is in a lit state and can display relevant content. At the same time, the display screen can normally receive any touch operation, and the electronic device can respond to and process any touch operation received.

It can be understood that, in the embodiment of the present application, the second touch operation refers to when the electronic device is in the second mode, Any touch operation that can be received on the display.

Exemplarily, in an embodiment of the present application, as shown in Figure 8, in the second mode, content is displayed on the display screen of the electronic device, and an upward swipe operation (second touch operation) is received through the display screen. The electronic device responds to the upward swipe operation, and the content on the display screen can slide upward to be displayed (processing corresponding to the second touch operation).

Exemplarily, in an embodiment of the present application, as shown in Figure 9, in the second mode, content is displayed on the display screen of the electronic device, and a right swipe operation (second touch operation) is received through the display screen. The electronic device responds to the right swipe operation, and the content on the display screen can slide to the right and be displayed (processing corresponding to the second touch operation).

Exemplarily, in an embodiment of the present application, as shown in FIG10 , in the second mode, content is displayed on the display screen of the electronic device, for example, multiple APPs, including APP1 and APP2, are displayed; a click operation (second touch operation) corresponding to APP1 is received through the display screen, so that the electronic device responds to the click operation corresponding to APP1 and displays the page content of entering APP1 on the display screen; further, the display screen can continue to receive any second touch operation based on the state of displaying the page content of APP1, and the electronic device can continue to respond and make corresponding processing.

Furthermore, in the embodiments of the present application, in addition to the first mode and the second mode, a third mode may also be included.

Further, FIG. 15 is a schematic diagram of a fifth implementation flow of the power supply method proposed in an embodiment of the present application. As shown in FIG. 15 , when the electronic device performs display processing through the display screen and receives a second touch operation through the display screen, in response to the second touch operation, before executing the processing corresponding to the second touch operation, that is, before step 402, the electronic device may further include the following steps:

Step 403: In the third mode, when a wake-up operation is received, the third mode is switched to the second mode in response to the wake-up operation.

In an embodiment of the present application, the electronic device may be in the third mode and, when a wake-up operation is received, switch from the third mode to the second mode in response to the wake-up operation before performing a processing corresponding to the second touch operation in response to the second touch operation while performing display processing through the display screen.

It should be noted that, in the embodiment of the present application, the third mode is a mode in which the display function and the touch function are turned off simultaneously.

That is to say, in the embodiment of the present application, the third mode is the off mode of the electronic device. In the third mode, the electronic device is in an off state and supports neither the touch function nor the display function.

Furthermore, in an embodiment of the present application, an electronic device in the third mode can be awakened by a preset wake-up method; for example, when the electronic device receives a preset wake-up operation, it can exit the third mode and enter the second mode; wherein the specific method of the wake-up operation is not limited in this application.

It should be noted that, in the embodiment of the present application, in the third mode, the first power supply circuit, the second power supply circuit and the chip power supply circuit are all in a closed state.

Illustratively, in an embodiment of the present application, as shown in FIG12 , when the electronic device is in the third mode, the first power supply circuit, the second power supply circuit, and the chip power supply circuit are all in an off state.

It can be understood that in the embodiment of the present application, in the third mode, the display screen is not powered, and the display function and the touch function are turned off at the same time. At this time, the electronic device cannot receive any touch operation through the display screen, that is, the touch is unresponsive; at the same time, the display screen is also in a black screen state, and no content is displayed.

Further, in an embodiment of the present application, in the third mode, when the electronic device receives a wake-up operation, it can switch from the third mode to the second mode in response to the wake-up operation.

Exemplarily, in an embodiment of the present application, the wake-up method is to wake up the electronic device by pressing a button; as shown in Figure 13, before the wake-up operation is performed, the display screen of the electronic device is in a power-off state, does not display any content, and does not support touch operations; when the electronic device receives a button operation (wake-up operation), the electronic device is awakened, the display screen exits the off mode, and the display function and the touch function are turned on. For example, after exiting the off mode, the power-on screen "welcome" is displayed, indicating that the second mode has been entered, and the touch function and the display function can be used normally.

It can be understood that in the embodiment of the present application, after the electronic device is switched from the third mode to the second mode, the display screen can turn on the display function and the touch function, so as to display the screen and receive the touch operation, that is, Enter normal use state.

It can be seen that the embodiment of the present application provides a multi-channel power supply solution that can meet the different power supply requirements of the display screen in various scenarios, while reducing the power consumption of the entire device and extending the standby time.

The embodiment of the present application provides a power supply method, which is applied to an electronic device with a display screen; when the electronic device receives a first touch operation through the display screen in the first mode, it switches from the first mode to the second mode in response to the first touch operation; wherein the first mode is a mode in which the signal processing voltage of the touch function is obtained through a first power supply circuit connected to the first chip; and the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through a second power supply circuit connected to the second chip. It can be seen that in the present application, when the electronic device is in the first mode, that is, when only the touch function needs to be used, the signal processing voltage of the touch function can be obtained through the first power supply circuit, so that the use of the touch function can be supported while maintaining low power consumption; and when the electronic device is in the second mode, that is, when the display function and the touch function need to be used at the same time, the signal processing voltage of the display function and the touch function is obtained through the second power supply circuit to support the use of the display function and the touch function at the same time, so that the power consumption of the electronic device can be effectively reduced and the standby time of the electronic device can be improved.

Based on the above embodiments, in another embodiment of the present application, exemplarily, a power supply method is provided, which is applied to a smart watch with a display screen; the overall power consumption of the smart watch can be reduced and the standby time of the smart watch can be increased.

It can be understood that, in the embodiments of the present application, the smart watch is a smart terminal that replaces the functions of a traditional watch.

Exemplarily, Figure 16 is a schematic diagram of the implementation of the power supply method proposed in an embodiment of the present application. As shown in Figure 16, in the hardware environment of the smart watch, it may include a battery, a main chip, a universal power control chip (first chip), a screen-specific power control chip (second chip) and other electronic devices; wherein the battery can provide electrical energy for the smart watch when in use; the chip processing voltage is the voltage provided to each chip, which is used for calculations within the chip; the first power supply circuit is connected to the universal power control chip, and the second power supply circuit is connected to the screen-specific power control chip; the first power supply circuit and the second power supply circuit both participate in the control of the signal processing voltage for the display function and the touch function.

That is to say, in the embodiment of the present application, for the smart watch, on the basis of the original display function and touch function sharing one chip, a signal processing voltage provided by a universal power processing chip is added for use by the chips for the display function and the touch function.

Furthermore, in an embodiment of the present application, as shown in Figure 16, the chip processing voltage of the smart watch can be provided by the chip power supply circuit of the first chip, and the signal processing voltage of the touch function and the display function can be provided by the first power supply circuit of the first chip or the second power supply circuit of the second chip.

Further, in an embodiment of the present application, the smart watch is equipped with a touch screen (display screen), which can support three usage scenarios, namely, click-to-light-screen mode (first mode), normal mode (second mode) and off mode (third mode); wherein, in click-to-light-screen mode, the touch screen does not display content, and can be awakened by touching the screen to display relevant content; click-to-light-screen mode can be used during the day, when the user is not using it, the screen is black, and the screen lights up by clicking on the screen; in normal mode, the touch screen display function and touch function are normally turned on, that is, it supports displaying content and touch operation; this is the state during normal use; in off mode, the touch screen is completely powered off, unable to display content, and has no response to touch, and needs to be awakened by a wake-up operation or the like to make the touch screen exit the off mode. The off mode can be used when sleeping at night to prevent users from accidentally touching the screen and waking up when wearing a smart watch at night.

Furthermore, in an embodiment of the present application, when the smart watch is in the first mode, when the first touch operation is received through the display screen, the smart watch switches from the first mode to the second mode in response to the first touch operation; wherein the first mode is a mode in which the signal processing voltage of the touch function is obtained through a first power supply circuit connected to the first chip; and the second mode is a mode in which the signal processing voltage of the display function and the touch function is obtained through a second power supply circuit connected to the second chip.

It should be noted that, in the embodiment of the present application, the power consumption of the first power supply circuit is less than the power consumption of the second power supply circuit.

It should be noted that, in the embodiment of the present application, the first mode is a mode in which the display function is turned off and the touch function is turned on.

That is to say, in the embodiment of the present application, the first mode is the click-to-light-screen mode. In the first mode, the display The screen does not display any content and is black. Only when the display screen receives the first touch operation, the electronic device will respond to the first touch operation and light up the screen.

As shown in Figure 4, during the day, when the user is not using the smart watch, the smart watch is in the first mode. In the first mode, the display screen of the smart watch is black and does not display any content. When the smart watch receives a touch operation (first touch operation) through the display screen, the screen lights up and displays relevant content, thereby entering the second mode.

It should be noted that, in the embodiment of the present application, in the first mode, the first power supply circuit is in the on state; and the second power supply circuit is in the off state.

As shown in Figure 5, when the electronic device is in the first mode, the first power supply circuit is in the on state and the second power supply circuit is in the off state. Since the power consumption of the first power supply circuit is low, its power supply capacity is insufficient to support the consumption of the display function. In this state, only the touch function is supported and the display function is turned off, effectively reducing the overall power consumption of the electronic device.

Further, as shown in FIG. 5 , in the first mode, the chip processing voltage for providing the internal computing function of the chip is provided by a chip power supply circuit connected to the first chip.

Furthermore, in an embodiment of the present application, the first touch operation refers to an operation of entering the second mode by touching the display screen of the electronic device in the first mode, thereby lighting up the display screen of the electronic device; for example, the first touch operation may be a click operation, and when the electronic device receives the click operation through the display screen, it may switch from the first mode to the second mode.

It can be seen that in the embodiments of the present application, for a smart watch, the state in which the screen is off but supports turning on the screen to light up by clicking on it (first mode) is a very common state; the present application optimizes the power consumption in this state. In the first mode, the first power supply circuit of the first chip is used to supply power to meet the signal processing voltage requirement; turning off the second power supply circuit can greatly reduce power consumption and extend the standby time of the smart watch.

Furthermore, in an embodiment of the present application, the second mode is a mode in which the display function and the touch function are turned on at the same time; in the second mode, the display function and the touch function of the smart watch are turned on normally, that is, the display content and touch operation are supported.

It should be noted that, in the embodiment of the present application, in the second mode, the first power supply circuit is in the off state; and the second power supply circuit is in the on state.

As shown in Figure 6, in the second mode, the first power supply circuit is turned off and the second power supply circuit is turned on. The second power supply circuit is used to provide signal processing voltage for the display function and the touch function. Since the second power supply circuit has a strong power supply capacity and can support the consumption of the display function, in the second mode, by turning on the second power supply circuit, the use of the display function and the touch function can be supported at the same time.

It can be understood that, in the embodiment of the present application, the power consumption of the smart watch in the second mode is greater than that in the first mode.

Further, in an embodiment of the present application, in the second mode, a chip processing voltage for providing a computing function inside the chip is provided by a chip power supply circuit connected to the first chip.

That is to say, in the embodiment of the present application, in the first mode or the second mode, the chip processing voltage is obtained through the chip power supply circuit connected to the first chip.

It can be seen that in an embodiment of the present application, in a scenario where the display function is not used and only the touch function is used, the smart watch can turn off the second power supply circuit that can support the display function but has higher power consumption, and use the first power supply circuit for power supply, thereby greatly reducing the power consumption of the smart watch in this scenario and extending the standby time of the smart watch.

Furthermore, in an embodiment of the present application, when the smart watch is in the second mode, display processing can be performed through the display screen, and when the smart watch receives a second touch operation through the display screen, in response to the second touch operation, processing corresponding to the second touch operation is performed.

That is to say, in an embodiment of the present application, when the smart watch is in the second mode, it can support both display function and touch function; when the smart watch is in the second mode, the display screen is lit and can display relevant content. At the same time, the display screen can normally receive any touch operation, and the smart watch can respond to and process any touch operation received.

As shown in FIG8 , in the second mode, the smart watch has content displayed on its display screen. The screen receives an upward swipe operation (a second touch operation), and the smart watch responds to the upward swipe operation, and the content on the display screen can be slid upward for display (processing corresponding to the second touch operation).

Further, as shown in Figure 9, in the second mode, for the smart watch, there is content displayed on its display screen, and a right swipe operation (second touch operation) is received through the display screen. The smart watch responds to the right swipe operation, and the content on the display screen can slide to the right to be displayed (processing corresponding to the second touch operation).

Further, as shown in FIG10 , in the second mode, for the smart watch, there is content displayed on its display screen, for example, multiple APPs, including APP1 and APP2; a click operation (second touch operation) corresponding to APP1 is received through the display screen, so that the electronic device responds to the click operation corresponding to APP1 and displays the page content of entering APP1 on the display screen; further, the display screen can continue to receive any second touch operation based on the state of displaying the page content of APP1, and the smart watch can continue to respond and make corresponding processing.

Furthermore, in an embodiment of the present application, the usage mode of the smart watch may include a third mode in addition to the first mode and the second mode.

It should be noted that, in the embodiment of the present application, the third mode is a mode in which the display function and the touch function are turned off simultaneously.

That is to say, in the embodiment of the present application, the third mode is the off mode of the smart watch. In the third mode, the smart watch is in an off state and supports neither the touch function nor the display function.

Furthermore, in an embodiment of the present application, a smart watch in the third mode can be awakened by a preset wake-up method; for example, when the smart watch receives a preset wake-up operation, it can exit the third mode and enter the second mode; wherein the specific method of the wake-up operation is not limited in this application.

It should be noted that, in the embodiment of the present application, in the third mode, the first power supply circuit, the second power supply circuit and the chip power supply circuit are all in a closed state.

As shown in FIG. 12 , in the third mode, the first power supply circuit, the second power supply circuit and the chip power supply circuit are all in a closed state.

It can be understood that in the embodiment of the present application, in the third mode, the display screen of the smart watch is not powered, and the display function and the touch function are turned off at the same time. At this time, the smart watch cannot receive any touch operation through the display screen, that is, the touch is unresponsive; at the same time, the display screen is also in a black screen state, and no content is displayed.

Further, in an embodiment of the present application, in the third mode, when the smart watch receives a wake-up operation, it can switch from the third mode to the second mode in response to the wake-up operation.

Exemplarily, as shown in FIG13 , for a smart watch, before the wake-up operation is performed, the display screen of the smart watch is in a power-off state, does not display any content, and does not support touch operations; when the smart watch receives a key operation (wake-up operation), it wakes up the electronic device, causes the display screen to exit the off mode, and turns on the display function and the touch function. For example, after exiting the off mode, the startup screen "welcome" is displayed, indicating that the second mode has been entered, and the touch function and the display function can be used normally.

In addition, it should be noted that, since the touch function and the display function are currently combined in one chip, it is an inevitable trend in the development of chip technology. When chip technology develops, when one chip can accommodate two highly coupled functions, it is inevitable that the two functions are placed in the same chip. For such technical requirements, a common chip for display function and touch function has emerged. This common chip cannot support the display function, and a dedicated power supply circuit is required to support the display function. The dedicated power supply circuit has an excessive surplus for the separate touch function, and the consumption of the dedicated power supply circuit itself is too large, which leads to the problem of high power consumption of the electronic device. Based on this, the embodiment of the present application proposes to add a signal processing voltage provided by the first power supply circuit of the first chip on the basis of the common chip for the display function and the touch function, so as to be used by the chip for the display function and the touch function; so that in the scenario where the display function is not used and only the touch function is used, the electronic device can turn off the second power supply circuit that can support the consumption of the display function but has a higher power consumption, and use the first power supply circuit for power supply, thereby greatly reducing the power consumption of the electronic device in this scenario and extending the standby time of the electronic device.

Furthermore, one or two output positions that can support the display function can be added to the universal power processing chip (first chip), so that the universal power processing chip can be directly used to provide signal processing circuits for the display function and the touch function. or when the power consumption of the dedicated power supply circuit (the second power supply circuit) can be reduced to an appropriate level, the dedicated power supply circuit can be directly used to provide the signal processing voltage for the display function and the touch function.

The embodiment of the present application provides a power supply method, wherein the electronic device is an electronic device with a display screen; when the electronic device is in a first mode, when receiving a first touch operation through the display screen, the electronic device switches from the first mode to the second mode in response to the first touch operation; wherein the first mode is a mode in which a signal processing voltage of a touch function is obtained through a first power supply circuit connected to a first chip; and the second mode is a mode in which a signal processing voltage of a display function and a touch function is obtained through a second power supply circuit connected to a second chip. It can be seen that in the present application, when the electronic device is in the first mode, that is, when only the touch function needs to be used, the signal processing voltage of the touch function can be obtained through the first power supply circuit, so that the use of the touch function can be supported while maintaining low power consumption; and when the electronic device is in the second mode, that is, when the display function and the touch function need to be used at the same time, the signal processing voltage of the display function and the touch function is obtained through the second power supply circuit to support the use of the display function and the touch function at the same time, so that the power consumption of the electronic device can be effectively reduced and the standby time of the electronic device can be improved.
