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 turning on a fingerprint sensor in at least one scanning area 14 corresponding to at least one trigger operation after at least one trigger operation of at least one finger of a user in the content display area 10 is detected so as to acquire at least one group of fingerprint data of the user in the at least one scanning area;

a data transmission line 13 connected to the plurality of fingerprint sensors 11 and the processing component 12 for transmitting at least one set of fingerprint data acquired by the fingerprint sensors in at least one scanning area to the processing component 12.

The processing unit 12 is further configured to compare at least one set of fingerprint data transmitted via the data transmission line 13 with the stored fingerprint data, and determine that the fingerprint authentication is successful when any one of the at least one set of fingerprint data is successfully compared with the stored fingerprint data.

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 at least one trigger operation of a finger of a user in the content display area, the processing component 12 starts the fingerprint sensor 11 in at least one scanning area corresponding to the at least one trigger operation, so as to implement local scanning in the content display area 10, avoid performing fingerprint scanning in the entire content display area 10, shorten the scanning time of the fingerprint sensor 11, and greatly reduce the power consumption of the fingerprint module; in addition, processing unit 12 compares through at least a set of fingerprint data of gathering user in at least one scanning area and the fingerprint data that has saved, has realized all can carrying out the fingerprint unblock in the whole content display area of screen module, need not change the finger, has improved the success rate of fingerprint unblock greatly. 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 and the plurality of sub-pixels on the color filter 11 are in one-to-one correspondence, 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, at least one trigger operation of a finger of a user in the content display area 10 is detected through the trigger detection structure on the screen module, and at least one scanning area corresponding to the at least one 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 activated state, and perform a local scanning on the fingerprint in the scanning area 14.

In one embodiment, the trigger detection mechanism comprises: and the touch functional component is used for triggering at least one touch operation detected by the touch functional component. In another embodiment, the trigger detection structure comprises: and the triggering operation is at least one 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 an embodiment, the trigger detection structure may be disposed in the screen module to detect at least one trigger operation of a user on the screen module, and determine the corresponding at least one trigger area. As an exemplary embodiment, when the screen module includes a touch function component, the touch function component may be used as a trigger detection structure to detect at least one touch operation of a user on 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.
