Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram of a screen module according to an exemplary embodiment of the present disclosure; as shown in fig. 1, the screen module may include:

the fingerprint module comprises a plurality of fingerprint sensors 11, wherein the fingerprint sensors 11 are positioned in a content display area 10 of the screen module and used for performing fingerprint acquisition; in one embodiment, the fingerprint sensor 11 may be made of a transparent material so as to avoid affecting the content display of the LCD display module 15 (see fig. 2). In one embodiment, the content display Area 10 refers to an Area on the screen module for implementing a content display function, such as a View Area (VA) of the LCD display module 15 corresponding to the screen module.

The processing component 12 is connected with the fingerprint module and is used for determining the access authority of the application program in the scanning area corresponding to the triggering operation after the triggering operation of the finger of the user in the content display area 10 is detected, and starting a fingerprint sensor in the scanning area to collect the fingerprint data of the user in the scanning area if the application program needs fingerprint authentication;

a data transmission line 13 connected to the plurality of fingerprint sensors 11 and the processing component 12 for transmitting fingerprint data collected by the fingerprint sensors within the scanning area to the processing component 12.

The processing component 12 is further configured to compare the fingerprint data acquired by the fingerprint sensor in the scanning area with the stored fingerprint data, and start an application program corresponding to the scanning area when the comparison between the fingerprint data acquired by the fingerprint sensor in the scanning area and the stored fingerprint data is successful.

In an embodiment, the fingerprint sensors 11 in the screen module correspond to the data transmission lines 13 one by one, and each fingerprint sensor 11 can perform fingerprint collection on a user at any time and transmit collected fingerprint data back to the processing unit 12 through the data transmission line 13.

In another embodiment, in order to reduce the number of data transmission lines 13 and simplify the lines, the data transmission lines 13 may be shared by a plurality of fingerprint sensors 11, i.e. the number of data transmission lines 13 in the screen module is smaller than the number of fingerprint sensors 11. Since there are few data transmission lines 13, a plurality of fingerprint sensors 11 sharing the same data transmission line 13 need to be time-multiplexed to transmit corresponding fingerprint acquisition data, and thus it is necessary to control the time when the fingerprint sensors 11 use the data transmission lines 13.

In this embodiment, after detecting the trigger operation of the finger of the user in the content display area 10, the processing component 12 starts the fingerprint sensor in the scanning area corresponding to the trigger operation, so as to implement local scanning in the content display area, avoid performing fingerprint scanning in the entire content display area, shorten the scanning time of the fingerprint sensor, and greatly reduce the power consumption of the fingerprint module; the processing component 12 compares the fingerprint data acquired by the fingerprint sensor in the scanning area with the stored fingerprint data, and when the fingerprint data acquired by the fingerprint sensor in the scanning area is successfully compared with the stored fingerprint data, starts the application program corresponding to the scanning area, ensures the login safety of the application program on the electronic equipment in a fingerprint authentication mode, and reduces the risk of property loss to the user after the electronic equipment is occupied by an illegal user. In addition, because the fingerprint sensor 11 is arranged in the screen module, a stacking structure does not need to be added on the physical keys of the mobile device, and the structure of the mobile device is simplified and the complexity is reduced.

Fig. 2 is a schematic perspective view illustrating an LCD display module of a screen module according to an exemplary embodiment of the present disclosure, and as shown in fig. 2, the LCD display module 15 in the screen module may include: backlight 21, lower polarizer 22, array glass substrate 23, liquid crystal layer 24, color filter 25 and upper polarizer 26; here, red (R), green (G), blue (B), and other sub-pixels are formed on the color filter 25.

See enlarged detail in fig. 2: taking a red sub-pixel as an example, only the lower left pixel area 251 of the whole area of the sub-pixel is used for displaying corresponding red content, and the upper right (for example, may be at other positions) Black Matrix (BM) area 254 is not used for displaying content.

Therefore, the vertical projection of the fingerprint sensor 11 can be located in the vertical projection of the BM region 254 of the sub-pixel of the LCD display module 15, thereby avoiding the influence on the normal display of the content of the LCD display module 15.

FIG. 3 is a schematic structural diagram of an LCD display module of the screen module according to an exemplary embodiment of the present disclosure; as shown in fig. 3, when the vertical direction projection of the fingerprint sensor 11 is located in the vertical direction projection of the BM region 254 of the sub-pixel of the LCD display module 15, the fingerprint sensor 11 can be directly disposed on the surface of the color filter 25, and is located in the BM region 254 (see fig. 2, and not labeled in fig. 3), and the plurality of fingerprint sensors 11 are in one-to-one correspondence with the plurality of sub-pixels on the color filter, so that the assembly processes such as the bonding of the LCD display module 15 and other components are not affected because the fingerprint sensor 11 is disposed inside the LCD display module 15.

Fig. 4 is a schematic structural diagram of a screen module according to another exemplary embodiment of the present disclosure, and fig. 5 is a partial schematic diagram of a fingerprint sensor on the screen module according to another exemplary embodiment of the present disclosure; as shown in fig. 4 and 5, the screen module may include a plurality of fingerprint sensors 11, the fingerprint sensors 11 are disposed in the content display area 10 of the screen module, the trigger detection structure on the screen module detects a trigger operation of a finger of a user in the content display area 10, and a scanning area corresponding to the trigger operation, when the trigger operation of the finger of the user in the content display area 10 is detected, the processing component 12 may determine the scanning area 14 corresponding to the trigger operation, switch the fingerprint sensor located in the scanning area 14 from a normally-off state to an activation state, and locally scan the fingerprint in the scanning area 14.

In one embodiment, the trigger detection mechanism comprises: and the touch functional component triggers the touch operation detected by the touch functional component. In another embodiment, the trigger detection structure comprises: and the triggering operation is the pressing operation detected by the pressure detection component. In this way, the trigger operation can be realized by a click operation or a slide touch operation of a finger on the content display area 10.

Compared with the technical scheme that the fingerprint sensor 11 is arranged in the back or front key of the mobile terminal in the related art, the fingerprint sensor is arranged in the content display area 10, when the content display area 10 is triggered by a finger, fingerprint acquisition is only carried out in the scanning area corresponding to the triggering operation, full-screen fingerprint scanning of the whole content display area 10 is avoided, and the power consumption of a fingerprint module is greatly saved; in addition, because the fingerprint sensor 11 is located in the content display area 10 of the screen module, the functional areas of "fingerprint collection" and "content display" are overlapped equivalently, and the functional area on the mobile device does not need to be occupied additionally, which is beneficial to shortening the length specification and the thickness specification of the mobile device, and further realizes the lightness and thinness of the mobile device.

For example, the control section 17 may control the gate control line 61, the gate control line 62, and the gate control line 63 to be sequentially turned on, and when the gate control line 61 is turned on and the gate control lines 62 and 63 are controlled to be turned off, the fingerprint sensor 611, the fingerprint sensor 612, and the fingerprint sensor 613 perform data transmission through the data transmission line 131, the data transmission line 132, and the data transmission line 133, respectively; when the gate control line 62 is turned on and the

Based on the screen module of the above embodiment, the present disclosure also provides a corresponding fingerprint authentication method, which is described in detail below.

Fig. 7A is a flowchart illustrating a fingerprint authentication method according to an exemplary embodiment of the present disclosure, and fig. 7B is a scene diagram illustrating a fingerprint authentication method according to an exemplary embodiment of the present disclosure, which is applied to the screen module according to any one of the above embodiments; as shown in fig. 7A, the method may include:

in step 701, a trigger area of a finger of a user in a content display area of a screen module is determined.

In an embodiment, a trigger detection structure may be disposed in the screen module to detect a trigger operation of a user in a content display area of the screen module, and determine a corresponding trigger area. As an exemplary embodiment, when the screen module includes a touch functional component, the touch functional component may be used as a trigger detection structure to detect a touch operation of a user on a content display area of the screen module; for example, the touch functional component may be composed of a touch screen and a corresponding transmission line, a control chip, and the like. As another exemplary embodiment, when the screen module includes a pressure detection component, the pressure detection component may be used as a trigger detection structure to detect a pressing operation of a user on a content display area of the screen module; for example, the pressure detection component may be composed of a pressure sensor and a corresponding transmission line, a control chip, and the like. Of course, the touch function module and the pressure detection module are used for illustration, and the trigger detection structure may be implemented by other structures, which is not limited by the disclosure.

In step 702, it is determined whether fingerprint authentication is required for the application corresponding to the trigger area.

In one embodiment, whether fingerprint authentication is required or not can be determined by determining the security level corresponding to the name of the application program corresponding to the trigger area, and in another embodiment, whether fingerprint authentication is required or not can be determined by determining whether the position of the trigger area is located in the fingerprint authentication area in the content display area or not.

In step 703, if the application corresponding to the trigger area needs to be authenticated, the fingerprint sensor in the trigger area is started to perform fingerprint collection.

In an embodiment, the trigger area may be determined according to a contact area between the finger and the content display area, and then the scanning area of the fingerprint may be determined according to the trigger area, and the scanning area corresponding to the fingerprint sensor corresponding to the fingerprint module may be turned on, so as to implement local scanning of the fingerprint sensor and reduce power consumption of the fingerprint module. As shown in fig. 4 and 5, a large number of fingerprint sensors are arranged in the content display area 10 to form a rectangular array with a large area, and the trigger operation of the user is detected by the trigger detection structure, so that the fingerprint sensors in the scanning area 14 in the rectangular array can be switched to the on state only during the existence of the trigger operation, and can be restored to the normally-off state after the trigger operation disappears, thereby reducing the power consumption of the fingerprint module to the maximum extent under the condition of ensuring that the fingerprint collection is realized in the scanning area.

In step 704, the fingerprint data collected by the fingerprint sensor in the trigger area is compared with the stored fingerprint data, and when the comparison between the fingerprint data and the stored fingerprint data is successful, the application program corresponding to the scanning area is started.

As an exemplary scenario, as shown in fig. 7B, when the user holds the electronic device with the right hand, the screen module may detect a trigger operation of a finger of the user at a "pay bank" icon in the content display area 10 of the screen module, at this time, it may be determined whether the "pay bank" needs to perform fingerprint authentication, if the "pay bank" needs to be started, the fingerprint sensor in the scanning area 71 further obtained by the trigger area is started, the fingerprint data collected by the user in the scanning area 71 is compared with the stored fingerprint data, and when the comparison between the collected fingerprint data and the stored fingerprint data is successful, it is determined that the fingerprint authentication passes, and the "pay bank" application program is started.

In the embodiment, after the triggering operation of the finger of the user in the content display area is detected, the fingerprint sensor in the scanning area corresponding to the triggering operation is started, so that the local scanning in the content display area is realized, the fingerprint scanning in the whole content display area is avoided, the scanning time of the fingerprint sensor is shortened, and the power consumption of the fingerprint module is greatly reduced; the fingerprint data collected by the fingerprint sensor in the scanning area is compared with the stored fingerprint data, when the fingerprint data collected by the fingerprint sensor in the scanning area is successfully compared with the stored fingerprint data, the application program corresponding to the scanning area is started, the login safety of the application program on the electronic equipment is ensured in a fingerprint authentication mode, and the risk of property loss to the user after the electronic equipment is occupied by an illegal user is reduced. In addition, because the fingerprint sensor sets up in the screen module, need not to increase stacked structure on mobile device's physics button, help simplifying mobile device's structure, reduce complicacy.

FIG. 8 is a flowchart illustrating a method of fingerprint authentication according to another exemplary embodiment of the present disclosure; the present embodiment takes as an example how to start the application program through fingerprint authentication after the trigger area of the user has been detected, and is exemplarily described with reference to fig. 7B, as shown in fig. 8, the following steps are included:

in step 801, the name of the application corresponding to the trigger area is determined.

In an embodiment, the system of the electronic device may monitor the application corresponding to the trigger area, and as shown in fig. 7B, when the user triggers the "pay treasure", the system of the electronic device may monitor that the "pay treasure" is triggered.

In step 802, it is determined whether the name of the application is already recorded in the authentication list, and if the name of the application is recorded in the authentication list, step 803 is performed, and if the name of the application is not recorded in the authentication list, step 806 is performed.

In one embodiment, the user may record the name of the application that needs fingerprint authentication in the authentication list, for example, for social or payment applications, the user may record the name of the social or payment application in the authentication list in order to ensure their privacy and property security.

In step 803, if the name of the application is recorded in the authentication list, it is determined that the access right of the application indicates that fingerprint authentication is required.

In step 804, a fingerprint sensor within the trigger zone is activated to perform fingerprint acquisition.

The description of step 804 can be referred to the following description of the embodiment shown in fig. 10, and will not be described in detail here.

In step 805, the fingerprint data collected by the fingerprint sensor in the trigger area is compared with the stored fingerprint data, and when the comparison between the fingerprint data and the stored fingerprint data is successful, the application program corresponding to the scanning area is started.

In one embodiment, different fingerprint data for comparison can be set for different application programs, for example, "pay pal" is set as the fingerprint of the thumb of the right hand of the user as the recorded fingerprint data, "Michai" is set as the fingerprint of the index finger of the left hand of the user as the recorded fingerprint data, and so on, thereby realizing that different application programs adopt different fingerprint data for fingerprint authentication, in another embodiment, more than two recorded fingerprint data can be set for the same application program, for example, "pay pal" is set as the fingerprint of five fingers on the right hand of the user as the fingerprint data to be compared, when the user holds the electronic device with the right hand, as long as any finger of the right hand triggers the "pay pal", the fingerprint data of the corresponding finger can be collected and compared with the stored fingerprint data, therefore, the user is prevented from changing the posture of holding the electronic equipment, and the experience of the user in fingerprint authentication is improved.

If the name of the application is not recorded in the authentication list, it is determined that the access right of the application indicates that fingerprint authentication is not required, and the application is started in step 806.

In the embodiment, any application program on the electronic equipment can have a corresponding fingerprint identification mode by associating the triggering area of the finger, the fingerprint authentication and the starting application program, so that the safety of user information related to the application program is improved; when a finger touches an application program on a screen of the electronic equipment, only fingerprint data of the trigger area needs to be collected, so that the power consumption of the fingerprint sensor is saved.

As shown in fig. 9B, a dotted line 91 divides the content display area 10 into a fingerprint authentication area 92 and a non-fingerprint authentication area 93, wherein an application placed in the fingerprint authentication area 92 needs to be authenticated to be able to start. In one embodiment, the ratio of the content display area 10 occupied by the fingerprint authentication area 92 and the non-fingerprint authentication area 93 can be set by user customization.

In step 902, if the trigger area is located in the fingerprint authentication area in the content display area, it is determined that fingerprint authentication needs to be performed on the application program corresponding to the trigger area to start a fingerprint sensor in the trigger area, so as to perform fingerprint collection.

In one embodiment, the trigger area may be identified in location to determine whether the trigger area is located in a fingerprint authentication area in the content display area.

In step 903, the fingerprint data acquired by the fingerprint sensor in the trigger area is compared with the stored fingerprint data, and when the comparison between the fingerprint data and the stored fingerprint data is successful, the application program corresponding to the scanning area is started.

In step 904, if the trigger area is not in the fingerprint authentication area in the content display area, it is determined that fingerprint authentication is not required for the application corresponding to the trigger area, and the application is started.

As an exemplary scenario, as shown in fig. 9B, the applications such as "pay pal", "m chat" and the like are located in the fingerprint authentication area 92, when a user triggers any one of the applications in the fingerprint authentication area 92, fingerprint authentication is required, for example, the user triggers "pay pal", if it is detected that the "pay pal" is located in the fingerprint authentication area 92, it is determined that fingerprint authentication needs to be performed on the "pay pal" corresponding to the trigger area to start a fingerprint sensor in the trigger area, so as to perform fingerprint collection, compare fingerprint data collected by the fingerprint sensor in the trigger area with stored fingerprint data, and when the fingerprint data is successfully compared with the stored fingerprint data, start the "pay pal", thereby avoiding a user changing a gesture of holding the electronic device, and improving a user experience of performing fingerprint authentication.

In the embodiment, the content display area is divided into the fingerprint authentication area and the non-fingerprint authentication area, so that a user can conveniently manage the application program installed on the electronic equipment, the fingerprint authentication area, the fingerprint authentication and the start application program are associated, when the application program located in the fingerprint authentication area on the electronic equipment is started, the fingerprint data of the user can be acquired, and the safety of user information related to the application program in the fingerprint authentication area is improved; when a finger touches an application program on a screen of the electronic equipment, only fingerprint data of the trigger area needs to be collected, so that the power consumption of the fingerprint sensor is saved.

In one embodiment, the trigger area may be a contact area of a finger with the content display area.

In step 1003, a scan area of the fingerprint is determined from the trigger area.

In an embodiment, the preset magnification factor may be obtained by counting the contact areas of a large number of fingers of the user, the preset magnification factor may be used to enlarge the contact area to a circular area capable of covering the contact area, and a tangent of the circular area along the first edge direction and the second edge direction is determined to obtain a scanning area 14 surrounded by a rectangular edge.

In step 1004, the corresponding fingerprint sensor in the scanning area is activated, and fingerprint acquisition is performed in the scanning area.
