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.

A wake-up method provided by an embodiment of the present invention is applied to a mobile terminal, and the mobile terminal may be a smart phone, a computer, a multimedia player, an e-reader, a wearable device, and the like. The bottom of the touch screen of the mobile terminal can be provided with a fingerprint sensor, and the user can complete fingerprint collection and recognition operations when touching the screen with a finger; further, the mobile terminal can support three-dimensional touch technology (Force-Touch), Force Touch technology It refers to the process of realizing the change of electrical data by sensing the generation and change of pressure, and then generating instructions through electrical data, and finally achieving the process of indirect instructions when pressure is reached. Through Force Touch technology, the mobile terminal can perceive the user's light touch on the touch screen. Press and press hard, and call out different corresponding functions.

A method, device and mobile terminal for waking up from an off-screen provided by the present invention will be described in detail below by enumerating several specific embodiments.

Embodiment one

Referring to FIG. 1 , it shows a flowchart of steps of a method for waking up from an off-screen according to an embodiment of the present invention, which may specifically include the following steps:

Step 101, when the touch screen is off, display a fingerprint sensing interface in a preset area of the touch screen.

In the embodiment of the present invention, the screen off of the mobile terminal means that the mobile terminal turns off the backlight and turns off the screen to save power. or messages, the mobile terminal can automatically turn on the screen for prompts, or when the user needs to use the mobile terminal, the screen can be turned on through the wake-up operation, and the off-screen of the mobile terminal can be turned off to save power when the mobile terminal is not in use , which can improve the battery life of the mobile terminal.

At present, the full-screen fingerprint unlocking technology has gradually matured. The next-generation smart phones of Apple, Samsung and other mobile phone manufacturers may cancel the fingerprint unlocking button and use the full-screen fingerprint unlocking technology. In the specific implementation, the full-screen fingerprint unlocking technology has two implementations Way:

Firstly, a fingerprint sensor can be arranged under the preset area of the touch screen, and when the user touches the preset area of the screen with a finger, the fingerprint collection and recognition operations can be completed through the fingerprint sensor.

The second type is to arrange a fingerprint sensor under the entire touch screen, and when the user touches any area of the screen with a finger, the fingerprint collection and identification operations can be completed through the fingerprint sensor.

Compared with the first implementation method, although the second implementation method has a larger area for fingerprint unlocking and more free operation, it requires a larger fingerprint sensor area and higher cost, so the first implementation method is currently used more widely.

Further, when the mobile terminal touches the off-screen screen, the off-screen display can always display the local touch screen where the preset area is located to display the fingerprint sensing interface. The preset area is used for fingerprint collection, as shown in Figure 1A. In the mobile terminal 100, the preset area 1001 is used to display the fingerprint sensing interface 1002 when the screen of the mobile terminal 100 is turned off. There may be various interface graphics for displaying the fingerprint sensing interface 1002, and it is used to remind the user of the fingerprint unlocking area.

It should be noted that there may be various positions of the preset area, and it is preferably a position convenient for the user to touch on the touch screen, which is not limited in this embodiment of the present invention.

Step 102, monitor whether there is a touch input operation in the preset area, and when a touch input operation is monitored in the preset area, collect the fingerprint of the touch input through the fingerprint sensor arranged below the preset area information.

In this step, a plurality of pressure sensors can be arranged symmetrically under the touch screen of the mobile terminal. The pressure sensors are used to monitor the touch input in each area of the touch screen, and at the same time determine the position coordinates of the touch input on the touch screen. When setting an area for touch operation, the pressure sensor can locate the coordinates of the touch input and notify the fingerprint sensor to collect fingerprint information. The whole process can be completed automatically when the mobile terminal is off the screen, and the whole collection process is fast and convenient.

In the embodiment of the present invention, the collection of fingerprint information is to scan and store the fingerprint of the user's finger placed in the preset area through the fingerprint sensor arranged under the preset area of the touch screen. The fingerprint sensor includes but is not limited to optical, ultrasonic, capacitance, etc. The principle of fingerprint detection may be integrated under the entire touch screen or under a preset area of the touch screen, which is not limited in this embodiment of the present invention.

Step 103, matching the fingerprint information with preset fingerprint information, and unlocking and waking up the touch screen if the matching is successful.

In the embodiment of the present invention, preset fingerprints of trusted users collected in advance are stored in the memory of the mobile terminal. There can be multiple preset fingerprints, which can be added or deleted by the user. After the fingerprint sensor is used to collect the fingerprint of the user's touch input in the preset area, the fingerprint is matched with all the fingerprints stored in the memory. If the match is successful, the access right is given to allow the user to unlock and wake up the touch screen of the mobile terminal. , if the match is successful, access is denied.

Fingerprint matching is based on fingerprint comparison technology. First, the clearest fingerprint image is selected through image processing technology. First, the fingerprint image of the human body is read through the fingerprint sensor. After the fingerprint image is obtained, the original image of the fingerprint image is initially processed. processing to make it clearer. Next, the digital identification template (characteristic data) of the fingerprint image is established through the fingerprint identification software, and two different fingerprints will not produce the same characteristic data. Finally, by computer fuzzy comparison method, compare the two fingerprint templates, calculate their similarity, and finally get the matching result of the two fingerprints.

To sum up, the embodiment of the present invention provides a wake-up method for the off-screen. When the touch screen is off, the fingerprint collection area is set in a certain area of the touch screen. When the user touches the fingerprint collection area with a finger, the preset area The fingerprint sensor installed below collects the user's fingerprint; and matches the collected touch input fingerprint with the preset fingerprint, and if the match is successful, unlocks and wakes up the touch screen. It is possible to perform fingerprint unlocking and wake up the touch screen through the touch screen when the screen of the mobile terminal is off. The unlocking operation is intuitive and convenient, which solves the problems of cumbersome wake-up and unlocking of the touch screen and poor user experience.

Embodiment two

Referring to FIG. 2 , it shows a flow chart of specific steps of a method for waking up from an off-screen according to an embodiment of the present invention, which may specifically include the following steps:

Step 201 , when the touch screen is off, display a fingerprint sensing interface in a preset area of the touch screen, and the preset area is used for fingerprint collection.

For this step, reference may be made to the above step 101, which will not be repeated here.

Optionally, step 201 may also include substep 2011 and substep 2012.

Sub-step 2011, if the touch screen includes a plurality of preset areas, when the touch screen is off, start from any one of the plurality of preset areas, and cycle through the first preset time period The plurality of preset areas are traversed, and when any preset area is traversed, the fingerprint sensing interface is displayed in the preset area.

In the embodiment of the present invention, when the screen is turned off, when the fingerprint sensing interface is continuously displayed in a certain area, it may have a certain impact on the life of the screen. Therefore, multiple preset areas can be set on the touch screen of the mobile terminal. By using The first preset time period loops through all preset areas. When traversing to a preset area, the fingerprint sensing interface is displayed in the preset area, which can reduce the negative impact on the life of the screen when the fingerprint sensing interface is continuously displayed in a certain area. Influence, and set the fingerprint sensor corresponding to the preset area, where multiple preset areas and corresponding fingerprint sensor settings can be implemented in the following two ways:

In the first implementation mode, a fingerprint sensor with an area equal to that of the touch screen can be set under the touch screen in the mobile terminal, that is, fingerprint collection can be completed in any area of the touch screen, and the user can independently set the preset area in the touch screen by setting the application. The location, the number of preset areas and the switching period can also be set, which increases the scalability of the fingerprint collection process.

Referring to Fig. 2A, the user can set area 110, area 120 and area 130 in advance as the fingerprint collection area in the touch screen according to his own usage habits. After turning on for 5 minutes, turn off the fingerprint sensing interface in area 110, and at the same time turn on area 120. After the area 120 is continuously lit for 5 minutes, turn off the fingerprint sensing interface in area 120, and lighten area 130 at the same time, and continuously cycle in turn, Until the user touches the lit area to collect fingerprints, the result of matching will be performed according to the collected fingerprints. If the matching is successful, the fingerprint sensing interface will no longer be displayed, and the touch screen will be unlocked and woken up. If the matching fails, the unlocking failure message will be prompted. At the same time, the above cycle continues, and it should be noted that the user can collect fingerprints only by touching the fingerprint sensing interface in the currently lit area.

In the second implementation mode, a certain number (greater than 1) of preset areas is preset in the touch screen of the mobile terminal, and a fingerprint sensor with the same area as the preset area is only set under the preset area, and any one of the preset areas is selected. The area is used as the starting point, and all the preset areas are cycled through in the first preset time period. When a preset area is traversed, the operation of the fingerprint sensing interface is displayed in the preset area.

Referring to FIG. 2A, an area 110, an area 120, and an area 130 are respectively provided on the left, middle and right parts of the touch screen as the fingerprint collection area in the touch screen. After 5 minutes of continuous lighting, turn off the fingerprint sensing interface in area 110, and light up area 120 at the same time. , until the user touches the illuminated area to collect fingerprints, then the matching result will be performed according to the collected fingerprints. If the matching is successful, the fingerprint sensing interface will no longer be displayed, and the touch screen will be unlocked and woken up. If the matching fails, an unlock failure message will be prompted. , while continuing the above cycle.

In the embodiment of the present invention, the first implementation mode has stronger expandability and autonomy than the second implementation mode, but because the fingerprint sensor area required to be set in the first implementation mode is relatively large, it requires higher cost , the embodiment of the present invention does not limit the selection of the first implementation manner and the second implementation manner.

The embodiment of the present invention dynamically and cyclically displays the fingerprint sensing interface in multiple areas of the touch screen, which reduces the display time of a single area in the off-screen state, reduces damage to the touch screen of the mobile terminal, and improves the service life of the touch screen.

Sub-step 2012, when the touch screen is off, in the preset area, start from any one of the multiple concentric circles displayed on the fingerprint sensing interface, and cycle through the second preset time period All concentric circles, when traversing to any concentric circle, display the concentric circles, and the display mode of the fingerprint sensing interface is the plurality of concentric circles with decreasing radii in turn.

Optionally, the concentric circles are the water ripple display mode.

In the embodiment of the present invention, in order to solve the negative impact on the life of the screen when the fingerprint sensing interface is continuously displayed in a certain area, it is also possible to set the fingerprint sensing interface in the preset area as a display mode of concentric circles of water ripples. It is displayed as an image composed of pixels flickering continuously, and its ripples are like water waves, which is highly aesthetic. By displaying multiple concentric circles with water ripples, the continuous working time of the pixels in the preset area of the touch screen of the mobile terminal can be reduced, and the negative impact on the screen life caused by the continuous display of the fingerprint sensing interface in a certain area can be reduced.

Specifically, referring to FIG. 2B , in the mobile terminal 100, the preset area 1003 is used to cyclically and sequentially display fingerprints composed of four concentric circles with decreasing radii of A, B, C, and D when the mobile terminal 100 is off-screen. The display mode of the induction interface is to start from any concentric circle, and the second preset time is the cycle. The concentric circle A with the largest radius is displayed in ascending order of radius, and then the concentric circle A is displayed in descending order of radius to the concentric circle with the smallest radius. D, or vice versa, for example, if the starting point is D, the display sequence is D, C, B, A, B, C, D, and the time interval between two adjacent concentric circles is 5 minutes; if the starting point is A, Then the display sequence is A, B, C, D, C, B, A, and the time interval between two adjacent concentric circles is 5 minutes; if the starting point is C, the display sequence can be C, B, A, B , C, D, or C, D, C, B, A, B, C, the time interval between two adjacent concentric circles is 5 minutes. The embodiment of the present invention does not limit the number of concentric circles.

It should be noted that, referring to sub-step 2011, if the touch screen includes multiple preset areas, the fingerprint sensing interface displayed in the multiple preset areas may also be the multi-concentric water ripple interface described in sub-step 2012, This embodiment of the present invention will not describe it in detail.

Step 202, monitor whether there is a touch input operation in the preset area, and when a touch input operation is monitored in the preset area, collect the fingerprint of the touch input through the fingerprint sensor arranged below the preset area information.

For this step, reference may be made to the above-mentioned step 102, which will not be repeated here.

Optionally, step 202 may also include sub-step 2021 and sub-step 2022 .

Sub-step 2021, monitor whether there is a touch input operation in the preset area, and when it is monitored that the touch input is a pressure touch input, read the information of the pressure touch input through the pressure sensor below the touch screen. Pressure value.

In the embodiment of the present invention, based on the Force-Touch technology, when the touch screen is pressed hard with a finger, a slight deformation will occur, and the gap between it and the metal bracket below will change, which in turn will cause a change in the self-inductance capacitance, the position of the press and the gap The variation of capacitance is different. The pressure sensor judges the position and strength of the pressing by identifying and calculating such changes. Therefore, the pressure sensor arranged under the touch screen of the mobile terminal can sense the strength and subtle deformation of the vertical direction generated by the user's pressing on the touch screen, and calculate the change as a pressure value.

Sub-step 2022, when the pressure value of the pressure touch input is greater than or equal to a preset pressure value, the fingerprint information of the pressure touch input is collected by the fingerprint sensor.

In this step, the pressure sensor transmits the pressure value to the CPU processing module, and the CPU processing module compares the received pressure value with the preset pressure threshold. The pressure threshold can be defaulted by the system or preset by the user according to their own needs. of. When the pressure value of the pressure touch input reaches the set pressure threshold, the fingerprint of the pressure touch input is collected by the fingerprint sensor.

It should be noted that, in this step, when the pressure value of the pressure touch input reaches the set pressure threshold, the vibration motor arranged under the touch screen will give vibration feedback according to the pressure of the user, that is, how much the user presses. Force, the vibration motor will feedback to the user how much force, the feedback force is transmitted to the user's finger through the touch screen, so that the user can clearly feel the change of the pressure value of the pressure touch input, and improve the user experience of the screen wake-up method.

It should be noted that the user can set the parameters of the Force-Touch function supported by the mobile terminal by calling the setting interface and opening the setting application, that is, setting the parameters of the pressure threshold that triggers the Force-Touch function. It should be noted that the parameters of the pressure threshold It can also be the default parameter of the system. When the user needs to modify it according to his own usage habits, he can modify the value of this parameter.

For example, you can set the sensitivity of Force-Touch in the setting application, which can have three kinds of sensitivity: weak, medium and strong, corresponding to three kinds of pressure threshold parameters from low to high, and can be set according to the user's usage habits.

By monitoring the touch input in the preset area, when the touch input is pressure touch input and the pressure value reaches the preset pressure threshold, the fingerprint sensor arranged below the preset area collects the fingerprint of the touch input, which can solve the problem of When accidentally touching the preset area of the touch screen of the mobile terminal, it will cause the problem of unlocking and waking up the touch screen.

Step 203, matching the fingerprint information with the preset fingerprint information, and unlocking and waking up the touch screen if the matching is successful.

For this step, reference may be made to the above step 103, which will not be repeated here.

Step 204, closing the fingerprint sensing interface.

In this step, after unlocking and waking up the touch screen, close the fingerprint sensing interface displayed on the touch screen, so as to prevent the fingerprint sensing interface from affecting the normal use of the mobile terminal.

To sum up, the embodiment of the present invention provides a wake-up method for the off-screen. When the touch screen is off, the fingerprint collection area is set in a certain area of the touch screen. When the user touches the fingerprint collection area with a finger, the preset area The fingerprint sensor installed below collects the user's fingerprint; and matches the collected touch input fingerprint with the preset fingerprint, and if the match is successful, unlocks and wakes up the touch screen.
