detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to Fig. 1, Fig. 1 is a flowchart of a fingerprint detection and unlocking method provided by an embodiment of the present invention, which is applied to an electronic device, and the electronic device includes a display screen, a fingerprint detection module and multiple detection modules, wherein the The fingerprint detection module and the plurality of detection modules are integrated in the display screen. As shown in Figure 1, the following steps are included:

Step 101, monitor whether there is an object approaching the display screen through the plurality of detection modules.

In step 101, the electronic device in the present invention may include a display screen, a fingerprint detection module and a plurality of detection modules, wherein the fingerprint detection module and the plurality of detection modules are integrated in the display screen. These detection modules can be used to monitor whether there is an object approaching the display screen of the electronic device. A plurality of detection modules can be a plurality of infrared detection modules, and can also be a plurality of ultrasonic detection modules, as long as the function of monitoring whether an object is close to the display screen of the electronic device can be realized, it is not used in the specific embodiments of the present invention. Specific limits.

As shown in FIG. 2 , it is a schematic diagram of multiple detection modules arranged in the display screen. The display screen of the electronic device can be divided into multiple areas, and a detection module can be set in each area. When the electronic device is turned on, these detection modules can always be in the working state. In order to reduce power consumption in the specific embodiments of the present invention, it is required that the fingerprint detection module cannot be continuously in the working state. Therefore, it is necessary to choose to keep the detection module in the working state all the time, and control and start the fingerprint detection module through the detection module. The power consumption of the multiple detection modules in the working state is lower than the power consumption of the fingerprint detection module in the working state.

When determining the number of divided regions, two factors need to be considered comprehensively: the success rate of object recognition and the total power consumption of multiple detection modules.

The case where the detection module is an infrared detection module will be described. The infrared detection module can include a transmitting tube and a receiving tube. The emission tube of the infrared detection module can emit infrared light signals at a certain frequency, for example, can emit infrared light signals at a frequency of 60 Hz. The emitted infrared light signal will be reflected back when it encounters an object, and the receiving tube of the infrared detection module can receive the infrared light signal reflected back by the object. Furthermore, the electronic device can obtain the energy value of the infrared light signal reflected by the object received by the receiving tube, and then determine whether there is an object approaching the display screen according to the obtained energy value of the infrared light signal reflected by the object.

If the divided areas are less, the number of infrared detection modules is less. Assuming that there is an object close to the display screen, once the object deviates far from the infrared detection module, the infrared light signal emitted by the emission tube of the infrared detection module may not touch the object close to the display screen, and may be misjudged as If there is no object close to the display, missed detection may occur. If you want to reduce the occurrence of missed detection, you can make more divided areas, that is, you can add a few more infrared detection modules. However, if the number of infrared detection modules is large, although the risk of missed detection can be reduced, the total power consumption of multiple infrared detection modules will be relatively large. Therefore, when determining the number of divided areas, that is, when determining the number of infrared detection modules, attention should be paid to reducing the risk of missed detection, and it is also necessary to ensure that the total power consumption of multiple infrared detection modules is low. Normally, dividing the display screen into 6-8 areas, that is, setting 6-8 infrared detection modules in the display screen can meet the requirements.

Step 102, if it is detected that there is an object approaching the display screen, determine the number of detection modules that have detected the object.

In step 102, as mentioned above, the receiving tube of the infrared detection module receives the infrared light signal reflected by the object, and after the electronic device obtains the energy value of the reflected infrared light signal, the electronic device can obtain the obtained The energy value of the reflected infrared light signal is compared with the preset threshold.

It should be noted that the longer the distance traveled by the infrared light signal emitted by the transmitting tube of the infrared detection module, the more the energy of the infrared light signal is attenuated, and the energy value of the infrared light signal received by the receiving tube of the infrared detection module The smaller the distance is, the shorter the distance the infrared light signal emitted by the transmitting tube of the infrared detection module passes, the less the energy attenuation of the infrared light signal is, and the energy value of the infrared light signal received by the receiving tube of the infrared detection module is bigger. Therefore, when the acquired energy value of the reflected infrared light signal is greater than a preset threshold, it can be determined that there is an object approaching the display screen.

Furthermore, the number of detection modules that detect objects close to the display screen can also be determined, that is, the number of infrared detection modules that detect objects close to the display screen can be determined.

Step 103, judging whether the quantity is smaller than a first threshold.

In step 103, after determining the number of detection modules that detect objects close to the display screen, that is, after determining the number of infrared detection modules that detect objects close to the display screen, the electronic device can further determine whether the number is less than first threshold.

Step 104, if the number is less than the first threshold, enable fingerprint detection.

In step 104 , as shown in FIG. 2 , assuming that the user wants to use the fingerprint to unlock the electronic device at this time, the user's finger will approach the display screen of the electronic device. If the user operates the electronic device with one hand, the user's thumb may block the two detection modules, that is, at this time, the two detection modules may detect an object approaching the display screen.

When the electronic device is placed in the pocket or the display screen of the electronic device is blocked by other objects, multiple detection modules placed in the display screen will detect that there is an object approaching the display screen. For example, there may be 4, 5 or even 6 detection modules all monitoring that there is an object approaching the display screen, and at this time, the fingerprint detection module may be activated by mistake.

Therefore, the first threshold can be set, for example, the first threshold can be set to 3. If the electronic device determines that the number of detection modules that detect objects close to the display screen is less than the first threshold, that is, it determines that the number of infrared detection modules that detect objects that are close to the display screen is less than the first threshold, that is, it determines that the detection If the number of infrared detection modules for objects close to the display screen is less than 3, it can be judged that the object is the user's finger, and then fingerprint detection can be enabled. For example, the full-screen fingerprint detection function can be turned on.

If the electronic device determines that the number of detection modules that detect objects close to the display screen is greater than or equal to the first threshold, that is, it determines that the number of infrared detection modules that detect objects close to the display screen is greater than or equal to the first threshold, it also That is, if it is determined that the number of infrared detection modules detecting an object close to the display screen is greater than or equal to 3, it can be determined that the object is not the user's finger, and then fingerprint detection may not be enabled. This can effectively reduce the occurrence of false start of the fingerprint detection module.

In the embodiment of the present invention, the above-mentioned electronic device can be any electronic device equipped with a display screen, a fingerprint detection module and a plurality of detection modules, such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) , personal digital assistant (PDA for short), mobile internet device (Mobile Internet Device, MID) or wearable device (Wearable Device), etc.

The fingerprint detection and opening method of the embodiment of the present invention is applied to an electronic device, and the electronic device includes a display screen, a fingerprint detection module and a plurality of detection modules, wherein the fingerprint detection module and the plurality of detection modules All are integrated and arranged in the display screen. Whether there is an object close to the display screen is monitored through the plurality of detection modules; if it is detected that an object is close to the display screen, then determine the number of detection modules that have detected the object; determine whether the number is less than the first A threshold; if the number is less than the first threshold, enable fingerprint detection. In this way, the electronic device in the embodiment of the present invention can monitor whether there is an object approaching the display screen through the detection module. If it is detected that there is an object approaching the display screen, it may be further determined whether the number of detection modules that detect the object is smaller than the first threshold. If the number is less than the first threshold, fingerprint detection is enabled; otherwise, fingerprint detection is not enabled. It can effectively reduce the occurrence of false start of the fingerprint detection module. And the power consumption of the electronic equipment is reduced, thereby prolonging the battery life of the electronic equipment.

Referring to Fig. 3, Fig. 3 is a flow chart of another fingerprint detection and opening method provided by an embodiment of the present invention, which is applied to an electronic device, and the electronic device includes a display screen, a fingerprint detection module and multiple detection modules, wherein, The fingerprint detection module and the plurality of detection modules are integrated in the display screen. The difference between this embodiment and the previous embodiment is that the fingerprint detection module includes multiple independent fingerprint detection sub-modules, and the multiple independent fingerprint detection sub-modules correspond to multiple detection modules. As shown in Figure 3, the following steps are included:

Step 301, monitor whether there is an object approaching the display screen through the plurality of detection modules.

In step 301, a plurality of detection modules can be used to monitor whether there is an object approaching the display screen of the electronic device. These detection modules are used to control and start the fingerprint detection module.

Optionally, the plurality of detection modules are all infrared detection modules

or

Ultrasonic detection module, and the display screen is divided into a plurality of areas, each area is provided with a detection module.

As mentioned in the first embodiment, the multiple detection modules may be multiple infrared detection modules, or multiple ultrasonic detection modules. As long as the function of monitoring whether there is an object approaching the display screen of the electronic device can be realized, it is not specifically limited in specific embodiments of the present invention. The working principle of the ultrasonic detection module to monitor whether there is an object approaching the display is similar to that of the infrared detection module, and will not be repeated here. The display screen of the electronic device can be divided into multiple areas, and a detection module can be set in each area.

The description is still made by taking the detection module as an infrared detection module. The infrared detection module can emit infrared light signals according to a certain frequency. The emitted infrared light signal will be reflected back when it encounters an object, and the infrared detection module can also receive the infrared light signal reflected back by the object. Furthermore, the electronic device can acquire the energy value of the infrared light signal reflected back by the object, and then determine whether there is an object approaching the display screen according to the acquired energy value of the infrared light signal reflected back by the object.

Step 302, if it is detected that there is an object approaching the display screen, determine the number of detection modules that have detected the object.

In step 302, after the electronic device acquires the energy value of the reflected infrared light signal, the electronic device may compare the acquired energy value of the reflected infrared light signal with a preset threshold. When the acquired energy value of the reflected infrared light signal is greater than the preset threshold, it can be judged that there is an object approaching the display screen. Further, the number of infrared detection modules that detect objects close to the display screen can also be determined.

Step 303, if no object is detected close to the display screen, then do not enable fingerprint detection.

In step 303, if the electronic device determines that the energy value of the acquired reflected infrared light signal is less than or equal to a preset threshold, it can determine that no object is detected approaching the display screen, and then fingerprint detection may not be enabled.

Step 304, judging whether the quantity is smaller than a first threshold.

In step 304, it is determined that there is an object approaching the display screen, and after determining the number of infrared detection modules that have detected the object approaching the display screen, the electronic device may further determine whether the number is less than a first threshold.

Step 305, if the number is less than the first threshold, enable fingerprint detection.

In step 305, if the electronic device determines that the number of infrared detection modules detecting an object close to the display screen is less than the first threshold, it can determine that the object is the user's finger, and then enable fingerprint detection. For example, the full-screen fingerprint detection function can be turned on.

Step 306, if the number is greater than or equal to the first threshold, then do not enable fingerprint detection.

In step 306, if the electronic device determines that the number of infrared detection modules detecting an object close to the display screen is greater than or equal to the first threshold, it may determine that the object is not the user's finger, and then may not enable fingerprint detection. This can effectively reduce the occurrence of false start of the fingerprint detection module.

Optionally, the fingerprint detection module includes a plurality of independent fingerprint detection sub-modules, the plurality of independent fingerprint detection sub-modules correspond to the plurality of detection modules, and the enabling of fingerprint detection includes :

Turn on the fingerprint detection sub-module corresponding to the detection module that detects the object close to the display screen to perform fingerprint detection.

Further, the fingerprint detection module may include multiple independent fingerprint detection sub-modules, and the multiple independent fingerprint detection sub-modules may correspond to multiple detection modules. If the electronic device determines that the number of detection modules that detect objects close to the display screen is less than the first threshold, it can turn on the fingerprint detection sub-modules corresponding to the detection modules that detect objects close to the display screen to perform fingerprint detection.

For example, assume that the display screen of the electronic device is divided into 6 areas, each area is provided with a detection module, and each area is provided with a fingerprint detection sub-module corresponding to the detection module. If the electronic device determines that there are two detection modules that detect objects close to the display screen, it can turn on the two fingerprint detection sub-modules corresponding to the two detection modules for fingerprint detection, and maintain the other four detection modules. A fingerprint detection sub-module is in sleep state. In this way, the power consumption of the electronic device can be further reduced, thereby further prolonging the battery life of the electronic device.

The electronic device in the embodiment of the present invention can monitor whether there is an object approaching the display screen through the detection module. If it is detected that there is an object approaching the display screen, it may be further determined whether the number of detection modules that detect the object is smaller than the first threshold. If the number is less than the first threshold, fingerprint detection is enabled; otherwise, fingerprint detection is not enabled. It can effectively reduce the occurrence of false start of the fingerprint detection module. Further, the fingerprint detection module may include multiple independent fingerprint detection sub-modules, and the multiple independent fingerprint detection sub-modules correspond to multiple detection modules. If the electronic device determines that an object close to the display screen is detected When the number of detection modules is less than the first threshold, the fingerprint detection sub-modules corresponding to the detection modules that detect objects close to the display screen can be turned on for fingerprint detection, and other fingerprint detection sub-modules are kept in a sleep state. The power consumption of the electronic equipment is further reduced, thereby further prolonging the battery life of the electronic equipment.
