[0029] Combine the following Figure 1-Figure 10 The infrared control circuit, method, device, and electronic device according to the embodiments of the present application are described in detail.

[0030] like Figure 1 As shown, an embodiment of the present application provides an infrared control circuit 100 .

[0031] The infrared control circuit 100 is applied to an electronic device 200 , which includes a power supply 202 , an infrared sensor 210 , and a power button 204 , an acceleration sensor 206 , and a screen 208 respectively connected to the power supply 202 .

[0032] Furthermore, the infrared control circuit 100 includes a signal conversion circuit 102 and an infrared enabling circuit 104 .

[0033] The signal conversion circuit 102 is connected to both the power source 202 and the power button 204 .

[0034] Furthermore, the infrared enabling circuit 104 is connected to the signal conversion circuit 102 , the acceleration sensor 206 , the screen 208 and the infrared sensor 210 .

[0035] Furthermore, the signal conversion circuit 102 is used to output a first signal according to the pressing state of the power button 204 .

[0036] The first signal is a high level or a low level, and is used to indicate whether the pressing state of the power button 204 changes.

[0037] Furthermore, the infrared enabling circuit 104 is used to receive a first signal from the power button 204 , a second signal from the acceleration sensor 206 , and a third signal from the screen 208 , and output an enabling signal to the infrared sensor 210 according to the first signal, the second signal, and the third signal.

[0038] The second signal is used to indicate the existence state (such as static state or motion state) of the electronic device 200.

[0039] Furthermore, the third signal is used to indicate the display status of the screen 208 (such as the screen-on status or the screen-off status).

[0040] Specifically, the infrared enabling circuit 104 is used to output a low-level enabling signal to the infrared sensor 210 to control the infrared sensor 210 to turn off, or to control the infrared sensor 210 to reduce the scanning frequency, when the first signal indicates that the pressing state of the power key 204 has not changed, the second signal indicates that the electronic device 200 is in a stationary state, and the third signal indicates that the screen 208 is in a screen-off state. If the first signal indicates that the pressing state of the power key 204 has changed, or the second signal indicates that the electronic device 200 is in a moving state, or the third signal indicates that the screen 208 is in a screen-on state, the infrared enabling circuit 104 is used to output a high-level enabling signal to the infrared sensor 210 to control the infrared sensor 210 to turn on.

[0041] In this way, the infrared sensor 210 can be controlled to work normally in application scenarios that require infrared functions, such as shielding and preventing accidental touches of the electronic device 200 and turning off the screen when the phone is close to the ear. In application scenarios that do not require infrared functions, such as when the screen of the electronic device 200 is turned off, the screen is still, and there is no fluctuation of the power button 204, the infrared sensor 210 can be controlled to turn off or the scanning frequency of the infrared sensor 210 can be reduced. In this way, the power consumption of the infrared sensor 210 is reduced, saving power resources.

[0042] It is understandable that in the related art, such as Figure 5 As shown, the hardware architecture of the infrared control circuit includes a power supply, a power button, an accelerometer, a controller / processor, a screen, and an infrared sensor. Among them, the controller / processor is connected to the infrared sensor through I2C (Inter-Integrated Circuit, two-wire serial bus) and EN (Enable) bus, the accelerometer is connected through the bus I2C or SPI (Serial Peripheral Interface, serial peripheral interface), and the screen and SOC (System on a Chip) are connected through the MIPI (Mobile Industry Processor Interface, mobile industry processor interface) bus. In addition, in the relevant technology, in all scenarios, the infrared sensor uses 100ms or other fixed cycles for continuous scanning. For example, in an application scenario where the electronic device is turned off, stationary, and the power button is not touched and no infrared function is required, the infrared sensor still scans according to 100ms or other fixed cycles. In this way, in application scenarios where the infrared function does not need to be turned on, the power consumption of the infrared sensor will increase, resulting in a waste of power resources.

[0043] Therefore, in the infrared control circuit 100 provided in the embodiment of the present application, a hardware circuit is added to control the infrared sensor 210 to turn off or reduce the scanning frequency when the pressing state of the power button 204 has not changed, the electronic device 200 is in a stationary state and the screen 208 is in a screen-off state, that is, in an application scenario where the electronic device 200 is off, stationary and the power button 204 is not touched and no infrared function is required, such as adjusting the scanning period of the infrared sensor 210 from 100ms to 500ms, so as to reduce the power consumption of the infrared sensor 210 and save power resources of the electronic device 200.

[0044] The infrared control circuit 100 according to the embodiment of the present application is applied to an electronic device 200, which includes a power supply 202, an infrared sensor 210, and a power key 204, an acceleration sensor 206, and a screen 208 respectively connected to the power supply 202. The infrared control circuit 100 includes a signal conversion circuit 102 and an infrared enabling circuit 104. The signal conversion circuit 102 is connected to the power supply 202 and the power key 204; the infrared enabling circuit 104 is connected to the signal conversion circuit 102, the acceleration sensor 206, the screen 208, and the infrared sensor 210. Further, the signal conversion circuit 102 is used to output a first signal according to the pressing state of the power key 204; the infrared enabling circuit 104 is used to receive the first signal, the second signal of the acceleration sensor 206, and the third signal of the screen 208, and output an enabling signal to the infrared sensor 210 according to the first signal, the second signal, and the third signal. Among them, when the first signal indicates that the pressing state of the power button 204 has not changed, the second signal indicates that the electronic device 200 is in a stationary state, and the third signal indicates that the screen 208 is in a screen-off state, the enable signal is at a low level to control the infrared sensor 210 to be turned off. Through the above-mentioned infrared control circuit 100, a hardware circuit is added to control the infrared sensor 210 to be turned off when the pressing state of the power button 204 has not changed, the electronic device 200 is in a stationary state, and the screen 208 is in a screen-off state. In this way, the infrared sensor 210 can be turned off in a scenario where the infrared function is not needed, thereby reducing the power consumption of the infrared sensor 210 and saving power resources.

[0045] According to some embodiments of the present application, optionally, the signal conversion circuit 102 is specifically used to: output a high-level first signal when the pressing state of the power button 204 changes, and output a low-level first signal when the pressing state of the power button 204 does not change.

[0046] Specifically, Figure 1 and Figure 2 As shown, in the infrared control circuit 100 provided in the embodiment of the present application, a signal conversion circuit 102 is added, and the signal conversion circuit 102 is equivalent to a monostable trigger. Every time the user presses or releases the power button 204, the signal conversion circuit 102 will alternately output a first signal of a high level or a low level at point A. For example, when the user presses the power button 204 once, the first signal output by the signal conversion circuit 102 at point A changes from a high level to a low level. When the user releases the power button 204, the first signal output by the signal conversion circuit 102 at point A changes from a low level to a high level.

[0047] Specifically, the control logic of the signal conversion circuit 102 is as follows: if the pressing state of the power key 204 changes, the output of the signal conversion circuit 102 is a high level 1, and if the pressing state of the power key 204 does not change, the output of the signal conversion circuit 102 is a low level 0. In this way, by the level of the first signal output by the signal conversion circuit 102, it can be determined whether the user is performing a key action.

[0048] According to the infrared control circuit 100 of the embodiment of the present application, the signal conversion circuit 102 is specifically used to: output a high-level first signal when the pressing state of the power key 204 changes, and output a low-level first signal when the pressing state of the power key 204 does not change. In this way, it is possible to determine whether the user is performing a key action by the level of the first signal output by the signal conversion circuit 102, thereby facilitating the subsequent determination of whether the application scenario of the electronic device 200 requires the use of the infrared function.

[0049] According to some embodiments of the present application, optionally, Figure 1 As shown, infrared enabling circuit 104 includes a logic OR gate 106 .

[0050] The logic OR gate 106 is connected to the signal conversion circuit 102 , the acceleration sensor 206 , the screen 208 and the infrared sensor 210 .

[0051] Furthermore, if Figure 1 As shown, the infrared control circuit 100 further includes a first resistor 108 and a second resistor 110 .

[0052] The first resistor 108 is connected to both the acceleration sensor 206 and the logic OR gate 106 .

[0053] Furthermore, the second signal includes an interrupt signal of the acceleration sensor 206 , and the interrupt signal is input to the logic OR gate 106 through the first resistor 108 .

[0054] When the electronic device 200 is in motion, the interrupt signal is at a high level, and when the electronic device 200 is in a stationary state, the interrupt signal is at a low level. Thus, the existence state of the electronic device 200 can be determined by the level of the interrupt signal, thereby determining whether the electronic device 200 is in motion or stationary state.

[0055] Furthermore, the second resistor 110 is connected to both the screen 208 and the logic OR gate 106 .

[0056] Further, the third signal includes a power supply signal of the screen 208 .

[0057] In actual application, the power supply signal may be specifically an enable signal of a DDIC (Display Driver Integrated Circuit) or an enable signal of a Panel (panel / control board) power supply 202IC (Integrated Circuit). The power supply signal is converted into a digital signal through the second resistor 110 and input into the logic OR gate 106.

[0058] When the screen 208 is in the on state, the power supply signal is at a high level, and when the screen 208 is in the off state, the power supply signal is at a low level. Thus, the display state of the screen 208 can be determined by the level of the power supply signal, thereby determining whether the screen 208 is in the on state or the off state.

[0059] It is understandable that when the screen 208 is in the bright screen state, it is necessary to turn on the infrared function for occlusion detection, proximity detection, etc., so that when the electronic device 200 is detected to be close to the user's ear during a call, the screen 208 is controlled to perform the action of turning off the screen or reducing the brightness. Furthermore, when the electronic device 200 is in motion, such as when the user picks up the electronic device 200 or puts the electronic device 200 in the pocket and walks, the infrared function needs to be turned on to realize the pocket anti-mistouch function. Furthermore, when the power button 204 jumps, it means that the user needs to start the button function, which means that the user needs to use the electronic device 200. At this time, the electronic device 200 will have certain actions such as turning on and off the screen and shaking, and the infrared function also needs to be turned on.

[0060] Therefore, in the infrared control circuit 100 provided in the embodiment of the present application, when the first signal, the interrupt signal and the power supply signal are all at low levels, that is, when the pressing state of the power button 204 does not change, the electronic device 200 is in a stationary state and the screen 208 is in a screen-off state, that is, when the electronic device 200 is off, stationary and the power button 204 is not touched, and the infrared function is not required, the logic OR gate 106 outputs a low-level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn off, or control the infrared sensor 210 to reduce the scanning frequency. When there is a high level in the first signal, the interrupt signal and the power supply signal, that is, when the pressing state of the power button 204 changes, or the electronic device 200 is in a moving state, or the screen 208 is in a bright screen state, that is, when the electronic device 200 is bright, moving or the power button 204 fluctuates, and other application scenarios that require infrared functions, the logic OR gate 106 outputs a high-level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn on, and perform scanning according to the high-frequency scanning frequency. In this way, in an application scenario where the infrared function is not required, the infrared sensor 210 is controlled to be turned off or the scanning frequency of the infrared sensor 210 is reduced, thereby reducing the power consumption of the infrared sensor 210 and saving power resources.

[0061] For example, Figure 3 As shown, when the user turns over the electronic device 200 or raises his wrist while holding the electronic device 200, the acceleration sensor 206 detects that the electronic device 200 is in motion, and inputs a high-level interrupt signal to the logic OR gate 106. At this time, the logic OR gate 106 outputs a high-level enable signal to control the infrared sensor 210 to turn on. Alternatively, the user performs a key operation on the power key 204, and the signal conversion circuit 102 inputs a high-level first signal to the logic OR gate 106 based on the jump of the power key 204. At this time, the logic OR gate 106 outputs a high-level enable signal to control the infrared sensor 210 to turn on. Alternatively, the user performs operations such as clicking on the screen 208, inputting a fingerprint, waking up the screen 208, etc., and the screen 208 is in a bright screen state, and a high-level power supply signal is input to the logic OR gate 106. At this time, the logic OR gate 106 outputs a high-level enable signal to control the infrared sensor 210 to turn on. On the contrary, when the screen 208 is off, the electronic device 200 is stationary, and the power button 204 is not touched, the logic OR gate 106 outputs a low-level enable signal to control the infrared sensor 210 to turn off and reduce the scanning frequency.

[0062] According to the infrared control circuit 100 of the embodiment of the present application, the infrared enabling circuit 104 includes: a logic OR gate 106, which is connected to the signal conversion circuit 102, the acceleration sensor 206, the screen 208 and the infrared sensor 210; the infrared control circuit 100 also includes: a first resistor 108, which is connected to the acceleration sensor 206 and the logic OR gate 106, and the second signal includes an interrupt signal of the acceleration sensor 206. When the electronic device 200 is in motion, the interrupt signal is a high level, and when the electronic device 200 is in a stationary state, the interrupt signal is a low level; a second resistor 110, which is connected to the screen 20 8 is connected to the logic OR gate 106, the third signal includes a power supply signal of the screen 208, when the screen 208 is in the screen-on state, the power supply signal is high level, when the screen 208 is in the screen-off state, the power supply signal is low level; the logic OR gate 106 is used to: when the first signal, the interrupt signal and the power supply signal are all low level, output a low level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn off; when there is a high level in the first signal, the interrupt signal and the power supply signal, output a high level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn on. In this way, in the application scenario where the infrared function is not required, the infrared sensor 210 is turned off, the power consumption of the infrared sensor 210 is reduced, and power resources are saved.

[0063] According to some embodiments of the present application, optionally, Figure 2 As shown, infrared enabling circuit 104 includes infrared controller 112 .

[0064] The infrared controller 112 is connected to the signal conversion circuit 102 , the acceleration sensor 206 , the screen 208 and the infrared sensor 210 .

[0065] Further, the second signal includes the first working signal of the acceleration sensor 206. The infrared controller 112 can receive the first working signal of the acceleration sensor 206, and determine whether the electronic device 200 is in a static state or in a moving state according to the change information of the first working signal.

[0066] Further, the third signal includes a second working signal of the screen 208. The infrared controller 112 can receive the second working signal of the screen 208, and determine whether the display state of the screen 208 is the off screen state or the on screen state according to the change information of the second working signal.

[0067] Furthermore, the infrared controller 112 is also used to receive the first signal output by the signal conversion circuit 102 .

[0068] In the infrared control circuit 100 provided in the embodiment of the present application, when the infrared controller 112 determines that the first signal is at a low level, the electronic device 200 is in a stationary state, and the screen 208 is in a screen-off state, the infrared controller 112 determines that the electronic device 200 does not need to use the infrared function, and outputs a low-level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn off. When the infrared controller 112 determines that the first signal is at a high level, or the electronic device 200 is in a moving state, or the screen 208 is in a bright screen state, the infrared controller 112 determines that the electronic device 200 needs to use the infrared function, and outputs a high-level enable signal to the infrared sensor 210 to control the infrared sensor 210 to turn on. In this way, in an application scenario where the infrared function is not required, the infrared sensor 210 is turned off, the power consumption of the infrared sensor 210 is reduced, and power resources are saved.

[0069] That is, in the infrared control circuit 100 provided in the embodiment of the present application, Figure 4 As shown, the working process of the infrared controller 112 may specifically include the following S302 to S310:

[0070] S302: Determine: the screen is on, if so, execute S308, if not, execute S304.

[0071] S304: Determine: the electronic device is stationary, if so, execute S306, if not, execute S308.

[0072] S306: Determine: the power button has changed, if so, execute S308, if not, execute S310.

[0073] S308: Control the infrared sensor to work in mode 1: high frequency scanning.

[0074] S310: Control the infrared sensor to work in mode 2: off.

[0075] Specifically, in the infrared control circuit 100 provided in the embodiment of the present application, the infrared controller 112 first determines whether the screen 208 is in a bright screen state. When the screen 208 is in a bright screen state, it is necessary to turn on the infrared function for occlusion detection, proximity detection, etc., so that when the electronic device 200 is detected to be close to the user's ear during a call, the screen 208 is controlled to perform the action of turning off the screen or reducing the brightness. At this time, the infrared controller 112 controls the infrared sensor 210 to work in mode one to perform high-frequency scanning. Further, when the screen 208 is in the off-screen state, the infrared controller 112 further determines whether the electronic device 200 is in a stationary state. When the electronic device 200 is in a moving state, such as when the user picks up the electronic device 200 or puts the electronic device 200 in a pocket and walks, the infrared function needs to be turned on to realize the pocket anti-mistouch function. At this time, the infrared controller 112 controls the infrared sensor 210 to work in mode one to perform high-frequency scanning. Furthermore, when the electronic device 200 is in a stationary state, the infrared controller 112 further determines whether the power button 204 has a jump. When the power button 204 has a jump, it means that the user needs to start the key function, that is, it means that the user needs to use the electronic device 200, and the electronic device 200 will have certain screen on and off, shaking and other actions. At this time, in order to ensure the normal infrared function of the electronic device 200, the infrared controller 112 will also control the infrared sensor 210 to work in mode 1 to perform high-frequency scanning. Further, when the power button 204 does not jump, the infrared controller 112 determines that the electronic device 200 currently does not need the infrared function, and controls the infrared sensor 210 to work in mode 2, that is, turn off the infrared sensor 210 to save the power consumption of the infrared sensor 210.

[0076] In this way, by adding hardware circuits and optimizing software processes, in application scenarios where the infrared function is not needed, turning off the infrared sensor 210 or reducing the scanning frequency of the infrared sensor 210 can reduce the power consumption of the infrared sensor 210 and achieve the purpose of reducing the power consumption of infrared devices.

[0077] For example, if the user uses the infrared function for 0.21 hours a day, the infrared control circuit 100 of the embodiment of the present application can control the infrared sensor 210 to be turned off for more than 23 hours. According to the calculation that 1 mA of power is consumed per hour when the infrared sensor 210 is turned on, 23 mAh of power can be saved in a day, thereby saving the power consumption of the infrared sensor 210.

[0078] According to the infrared control circuit 100 of the embodiment of the present application, the infrared enabling circuit 104 includes: an infrared controller 112, which is connected to the signal conversion circuit 102, the acceleration sensor 206, the screen 208 and the infrared sensor 210; wherein the second signal includes the first working signal of the acceleration sensor 206, and the third signal includes the second working signal of the screen 208; the infrared controller 112 is used to: determine the existence state of the electronic device 200 according to the change information of the first working signal, and determine the display state of the screen 208 according to the change information of the second working signal; when the first signal is low level, the electronic device 200 is in a stationary state and the screen 208 is in a screen-off state, output a low-level enabling signal to the infrared sensor 210 to control the infrared sensor 210 to turn off; when the first signal is high level, or the electronic device 200 is in a moving state, or the screen 208 is in a bright screen state, output a high-level enabling signal to the infrared sensor 210 to control the infrared sensor 210 to turn on. In this way, in an application scenario where the infrared function is not required, the infrared sensor 210 is turned off, which reduces the power consumption of the infrared sensor 210 and saves power resources.

[0079] According to some embodiments of the present application, optionally, Figure 1 and Figure 2 As shown, the signal conversion circuit 102 includes a third resistor 114 , a fourth resistor 116 , a first capacitor 118 , a first transistor 120 , a fifth resistor 122 , a sixth resistor 124 , a seventh resistor 126 , a second transistor 128 , a diode 130 , an eighth resistor 132 and a second capacitor 134 .

[0087] In the infrared control circuit 100 provided in the embodiment of the present application, a signal conversion circuit 102 is added as a monostable trigger. When the pressing state of the power key 204 changes, the signal conversion circuit 102 outputs a high-level first signal. When the pressing state of the power key 204 does not change, the signal conversion circuit 102 outputs a low-level first signal. In this way, the level of the first signal output by the signal conversion circuit 102 can be used to determine whether the user is performing a key action.

In this way, the level of the first signal output by the signal conversion circuit 102 can be used to determine whether the user is performing a key action, which is convenient for subsequent determination of whether the application scenario of the electronic device 200 needs to use the infrared function.

[0089] Alternatively, if Figure 7 As shown, the embodiment of the present application also provides an infrared control method, which is applied to an electronic device, wherein the electronic device includes an infrared sensor, a power button, an acceleration sensor, and a screen. The infrared control method may specifically include the following S402 and S404:

[0090] S402: Acquire a first signal from a power button, a second signal from an acceleration sensor, and a third signal from a screen.

[0091] The infrared control method proposed in the embodiment of the present application is executed by an electronic device, which may specifically be a smart electronic device with infrared function, such as a smart phone, a tablet computer, a laptop computer, and a smart watch, and is not specifically limited here.

[0092] The first signal is a high level or a low level, and is used to indicate whether the pressing state of the power key changes. Specifically, when the pressing state of the power key changes, the first signal is a high level, and when the pressing state of the power key does not change, the first signal is a low level.

[0093] Furthermore, the second signal is used to indicate the existence state (such as a stationary state or a moving state) of the electronic device.

[0094] Furthermore, the third signal is used to indicate the display status of the screen (such as the screen-on status or the screen-off status).

[0095] S404: Outputting an enable signal to the infrared sensor according to the first signal, the second signal and the third signal to control the operation of the infrared sensor.

[0096] Specifically, in the infrared control method provided in the embodiment of the present application, a first signal of the power button, a second signal of the acceleration sensor, and a third signal of the screen are obtained, and then the pressing state of the power button is determined to be a jump according to the first signal, the existence state of the electronic device is determined to be a stationary state or a moving state according to the second signal, and the display state of the screen is determined to be a bright screen state or a screen off state according to the third signal. On this basis, based on the determined pressing state of the power button, the existence state of the electronic device, and the display state of the screen, an enable signal is output to the infrared sensor to control the operation of the infrared sensor.

[0097] Among them, when the first signal indicates that the pressing state of the power button has not changed, the second signal indicates that the electronic device is in a stationary state, and the third signal indicates that the screen is in a screen-off state, the enable signal is at a low level to control the infrared sensor to be turned off. Furthermore, when the first signal indicates that the pressing state of the power button has changed, or the second signal indicates that the electronic device is in a moving state, or the third signal indicates that the screen is in a bright screen state, the enable signal is at a high level to control the infrared sensor to be turned on. In this way, the infrared sensor of the electronic device can be turned off in a scenario where the infrared function is not needed, which reduces the power consumption of the infrared sensor and saves the power resources of the electronic device.

[0098] The above-mentioned infrared control method provided in the embodiment of the present application is applied to an electronic device, and the electronic device includes an infrared sensor, a power button, an acceleration sensor and a screen. The infrared control method includes: obtaining a first signal of the power button, a second signal of the acceleration sensor and a third signal of the screen; outputting an enable signal to the infrared sensor according to the first signal, the second signal and the third signal to control the operation of the infrared sensor; wherein, when the first signal indicates that the pressing state of the power button has not changed, the second signal indicates that the electronic device is in a stationary state and the third signal indicates that the screen is in a screen-off state, the enable signal is a low level to control the infrared sensor to turn off. Through the above-mentioned infrared control method, when the pressing state of the power button has not changed, the electronic device is in a stationary state and the screen is in a screen-off state, the infrared sensor is controlled to turn off. In this way, the infrared sensor of the electronic device can be turned off in a scenario where the infrared function is not needed, which reduces the power consumption of the infrared sensor and saves the power resources of the electronic device.

[0100] S404a: When the first signal, the interrupt signal and the power supply signal are all at low levels, output a low-level enable signal to the infrared sensor to control the infrared sensor to be turned off.

[0101] The interrupt signal is a high level or a low level, and is used to indicate the existence state (such as a stationary state or a moving state) of the electronic device.

[0102] Specifically, when the electronic device is in motion, the interrupt signal is at a high level, and when the electronic device is in a stationary state, the interrupt signal is at a low level. Thus, the existence state of the electronic device can be determined by the level of the interrupt signal, thereby determining whether the electronic device is in motion or stationary state.

[0103] Furthermore, the power supply signal is a high level or a low level, and the power supply signal is used to indicate the display state of the screen (such as a screen-on state or a screen-off state).

[0104] Specifically, when the screen is in the off state, the power supply signal is at a low level. Thus, the display state of the screen can be determined by the level of the power supply signal, thereby determining whether the screen is in the on state or the off state.

When the first signal, the interrupt signal and the power supply signal are all at low levels, that is, when the pressing state of the power button has not changed, the electronic device is in a stationary state and the screen is in an off state, that is, when the electronic device is off, stationary and the power button is not touched in an application scenario where the infrared function is not required, a low-level enable signal is output to the infrared sensor to control the infrared sensor to turn off, or to control the infrared sensor to reduce the scanning frequency. In this way, in an application scenario where the infrared function is not required, the infrared sensor is controlled to turn off or the scanning frequency of the infrared sensor is reduced, which reduces the power consumption of the infrared sensor and saves power resources.

[0107] S404b: When the first signal, the interrupt signal and the power supply signal are at a high level, output a high level enable signal to the infrared sensor to control the infrared sensor to turn on.

In this way, it is ensured that the electronic device can use the infrared function normally in application scenarios requiring infrared function.

[0109] In the above embodiment provided by the present application, the second signal includes an interrupt signal of the acceleration sensor, and the third signal includes a power supply signal of the screen. When the first signal, the interrupt signal, and the power supply signal are all at low levels, a low-level enable signal is output to the infrared sensor to control the infrared sensor to be turned off; when the first signal, the interrupt signal, and the power supply signal are at high levels, a high-level enable signal is output to the infrared sensor to control the infrared sensor to be turned on. In this way, while ensuring that the electronic device can use the infrared function normally, the power consumption of the infrared sensor is reduced, saving power resources.

[0112] Specifically, in the infrared control method provided in the embodiment of the present application, the second signal includes the first working signal of the acceleration sensor. The electronic device can obtain the first working signal of the acceleration sensor and determine whether the existence state of the electronic device is a stationary state or a moving state based on the change information of the first working signal.

[0113] S404d: Determine the display state of the screen according to the change information of the second working signal.

[0114] Specifically, in the infrared control method provided in the embodiment of the present application, the third signal includes the second working signal of the screen. The electronic device can obtain the second working signal of the screen and determine whether the display state of the screen is the screen-off state or the screen-on state based on the change information of the second working signal.

[0115] S404e: When the first signal is at a low level, the electronic device is in a stationary state, and the screen is in an off state, a low-level enable signal is output to the infrared sensor to control the infrared sensor to be turned off.

[0116] Specifically, in the infrared control method provided in the embodiment of the present application, when the first signal is at a low level, the electronic device is in a stationary state, and the screen is in a screen-off state, it is determined that the electronic device does not need to use the infrared function. At this time, a low-level enable signal is output to the infrared sensor to control the infrared sensor to turn off or reduce the scanning frequency. In this way, in an application scenario where the infrared function is not required, the infrared sensor is controlled to turn off or the scanning frequency of the infrared sensor is reduced, thereby reducing the power consumption of the infrared sensor and saving power resources.

[0117] S404f: When the first signal is at a high level, or the electronic device is in motion, or the screen is in a bright screen state, a high level enable signal is output to the infrared sensor to control the infrared sensor to turn on.

[0118] Specifically, in the infrared control method provided in the embodiment of the present application, when the first signal is at a high level, or the electronic device is in motion, or the screen is in a bright screen state, it is determined that the electronic device needs to use the infrared function. At this time, a high-level enable signal is output to the infrared sensor to control the infrared sensor to turn on and perform scanning at a high-frequency scanning frequency. In this way, it is ensured that the electronic device can use the infrared function normally in an application scenario where the infrared function is required.

[0119] In the above-mentioned embodiment provided by the present application, the second signal includes the first working signal of the acceleration sensor, and the third signal includes the second working signal of the screen.
