Moreover, the fingerprint recognition under the screen can be realized at any position in the display area, and the flexibility and convenience of the fingerprint recognition can be improved.
The drawings described herein are intended to provide a further understanding of the application, and are intended to be a part of this application. The illustrative exemplary embodiments of the application and the description thereof are intended for explaining the application and do not constitute an undue limitation to the application. In the drawings:
At present, in an electronic device such as a mobile phone, a fingerprint recognition module is generally arranged at a Home button of a non-display area, or is arranged at a specific position under a screen of a display area, and prompts a user to recognize a location of the fingerprint in a constantly bright manner.
However, in the existing fingerprint recognition scheme, the position of the fingerprint recognition module is fixed, and a limitation of a fingerprint recognition operation is large. Sometimes an illumination sub-pixel arranged at a position of the fingerprint recognition module needs to be set to be constantly bright, and a power consumption is high and affects a lifetime of a device.
In order to make the objects, the technical solution and the advantages of the application clear, the technical solution of the application will be dearly and completely described in the following with reference to the specific exemplary embodiments of the application and the corresponding drawings. It is apparent that the described exemplary embodiments are only a part of the embodiments of the application rather than all of them. All other embodiments obtained by a person skilled in the art based on the exemplary embodiments of the application without paying creative work fall into the protection scope of the application.
The technical solution provided by the exemplary embodiments of the application is described in detail below with reference to the accompanying drawings.
It should be noted that the fingerprint recognition control solution involved in the application applies to a touch screen with a functional module such as a processor, or an electronic device with the touch screen, such as a mobile phone, a tablet computer, a VR, an AR, a wearable device, or other devices that need to be touched.
In the application, referring to
Step 11a: triggering a fingerprint recognition module to start and collecting a first fingerprint information when a fingerprint recognition instruction is detected. In an exemplary embodiment, the fingerprint recognition module may be a fingerprint recognition circuit.
The fingerprint recognition instruction involved may be an instruction triggered by performing a touch operation on the touch panel, or an instruction generated by triggering a voice control or an instruction sent by another terminal.
Step 12a: searching in a pre-stored fingerprint information list on whether there is a second fingerprint information matching with the first fingerprint information, and if yes, determining that a fingerprint recognition is successful.
Therefore, the fingerprint recognition under the screen can be realized at any position in the display area, the flexibility and convenience of the fingerprint recognition can be improved, the power consumption of the screen can be saved, and the fingerprint recognition under the screen of the full screen can be easily realized.
Referring to
Step 11b: determining a touch position corresponding to the touch operation when the touch operation is detected.
The touch position is located in a display area of the touch panel. In the application, the touch operation involved can be understood as the operation of the finger pressing any position in the touch screen corresponding to the display area.
In one implementation manner, a touch film layer of the touch panel can determine the touch position corresponding to a position on which the user's finger is pressing according to the touch signal collected by a sensor.
Further, in order to achieve a more accurate acquisition of fingerprint information, referring to
Step 111: detecting a pressing attribute of the touch operation.
Step 112: determining an area where the touch operation is implemented as the touch position corresponding to the touch operation, when the pressing property satisfies the preset condition.
In the application, for the touch operation, the pressing attribute may include: pressing force, pressing time, pressing manner, and the like. The pressing manner can be understood as a contact pressing or a non-contact pressing (i.e., a somatosensory pressing that is achieved by not touching the touch panel), or a rotational pressing in a certain direction after pressing, or a sliding operation or the like.
For example, when any position of the display area of the touch panel is detected to be touch-operated, the pressing force of the touch operation is detected. When the pressing force is greater than a first threshold, the area where the touch operation is implemented is determined as a touch position corresponding to the touch operation.
For example, when any position of the display area of the touch panel is detected to be touch-operated, the pressing time of the touch operation is detected, When the pressing time is greater than a second threshold, the area where the touch operation is implemented is determined as a touch position corresponding to the touch operation.
For example, when any position of the display area of the touch panel is detected to be touch-operated, the pressing force and the pressing time of the touch operation are detected, when the pressing force is greater than the first threshold and the pressing time is greater than the second threshold, the area where the touch operation is implemented is determined as a touch position corresponding to the touch operation.
Step 12b: triggering the fingerprint recognition module corresponding to the touch position to start, and collecting a first fingerprint information.
In the application, since the fingerprint recognition film layer corresponding to the fingerprint recognition module is arranged on the surface of the entire touch film layer, after determining the touch position corresponding to the touch operation, the fingerprint recognition modules corresponding to the entire fingerprint recognition film layer are not needed to start, and only the fingerprint recognition module at an area corresponding to the touch position is needed to start, so as to collect the fingerprint of the user performing the touch operation.
Specifically, after determining the touch position corresponding to the touch operation, the fingerprint recognition module corresponding to the touch position may be further determined according to the determined touch position, and then the fingerprint recognition module corresponding to the touch position is triggered to start to collect the first fingerprint information.
In the application, the means of collecting the first fingerprint information is optical fingerprint recognition, and correspondingly, it may be an infrared sensing element or other optical sensing elements. Then, in the exemplary embodiment, after the touch position is determined, the fingerprint recognition module is triggered to start, then the first fingerprint information is collected. This process may be regarded as the touch panel being always in a bright screen state; the fingerprint image at the touch position is collected to obtain the first fingerprint information by means of the light source supplied by the display film layer of the touch panel.
Optionally, in the application, in the case of the current touch panel is in a dark screen state, before the first fingerprint information is collected and after the touch position corresponding to the touch operation is determined, the method further includes: controlling an illuminating sub-pixel corresponding to the control position to light up. Therefore, the illuminating sub-pixel arranged below the touch film layer is partially lit up to assist the fingerprint recognition operation to provide a light source, thereby saving the screen power consumption; and the fingerprint recognition area can be highlighted to the user through the wake-up mode, to facilitates implementation of fingerprint pressing recognition.
Step 13b: searching in the pre-stored fingerprint information list on whether there is the second fingerprint information matching with the first fingerprint information, and if yes, determining that the fingerprint recognition is successful.
After the first fingerprint information is collected, the first fingerprint information is compared with the second fingerprint information in the pre-stored fingerprint information list to perform fingerprint recognition.
The second fingerprint information in the pre-stored fingerprint information list is added by a touch operation during a setting process, wherein the touch operation includes a single-finger touch operation or a multi-fingers touch operation.
For example, the fingerprint information list is equivalent to a fingerprint database formed by a fingerprint collected in advance, and the fingerprint database includes a plurality of second fingerprint information which may be multiple second fingerprint information of the same user, for example, a screen unlocking fingerprint information of the user A—the fingerprint information of a left thumb, a transaction verification fingerprint information—the fingerprint information of a right index finger, a logging verification fingerprint information—the fingerprint information of the left index finger, and the like.
Optionally, in the application, the touch position includes at least one independent area subjected to a touch operation; the first fingerprint information is at least one fingerprint information which is simultaneously collected by the fingerprint recognition module corresponding to at least one independent area.
Optionally, the first fingerprint information includes a plurality of fingerprint information collected simultaneously. Correspondingly, step 13b of searching in the pre-stored fingerprint information list on whether there is second fingerprint information which matches with the first fingerprint information specifically includes:
Step 131: traversing the second fingerprint information in the pre-stored fingerprint information list.
Step 132: finding whether the fingerprint information included in the second fingerprint information is the same as the fingerprint information included in the first fingerprint information.
For example, the first fingerprint information is collected when the touch panel is simultaneously touched and pressed by a left thumb of a user A and a right thumb of a user B. Then, when performing comparison of various fingerprint information, it is necessary to find out whether the second fingerprint information including both the fingerprint information of the left thumb of the user A and the fingerprint information of the right thumb of the user B exists in the pre-stored fingerprint information list, If yes, the fingerprint recognition is successful, otherwise, the fingerprint recognition fails.
Therefore, by the technical solution of the application, the startup of a corresponding fingerprint recognition module can be achieved by pressing any position of the display area of the touch panel without pressing a specific area, and without starting the fingerprint recognition module in the entire fingerprint recognition film layer as well, the power consumption of the screen can be saved, and the fingerprint recognition under the screen of the full screen can be easily realized. In addition, the fingerprint recognition under the screen can be realized at any position in the display area, the flexibility and convenience of the fingerprint recognition can be improved.
In fact, in the application, in a case of the display screen being in a bright screen state, after the fingerprint recognition is successful, the method further includes: unlocking the screen of the touch panel, or enabling a passed transaction verification, or enabling a passed login verification. In a case of the display screen being in a dark screen state, after the fingerprint recognition is successful in the case of partially lighting the illuminating sub-pixel, the method further includes: triggering to illuminate a display area of the touch panel, and/or unlocking the screen of the touch panel, or, enabling a passed transaction verification, or enabling a passed login verification.
In an exemplary embodiment of the application, a touch panel is further provided which belongs to the same concept as the above-mentioned fingerprint recognition control method. Referring to

In addition, the touch panel further includes at least one other module (or called elements) which controls the display.
Optionally, in the exemplary embodiment of application, the touch panel further includes:
a control module configured to control, when the touch panel is in a dark screen state, an illuminating sub-pixel corresponding to the control position to light up before the first fingerprint information is collected and after the touch position corresponding to the touch operation is determined. In an exemplary embodiment, the control module may be a control circuit.
Optionally, in the application, after the fingerprint recognition is successful, the processing module is further configured to:
trigger to light up a display area of the touch panel, and/or unlock a screen of the touch panel.
Optionally, in the application, the determining module is specifically configured to:

traverse the second fingerprint information in the pre-stored fingerprint information list;
find whether the fingerprint information included in the second fingerprint information is the same as the fingerprint information included in the first fingerprint information.
Optionally, the second fingerprint information in the pre-stored fingerprint information list is added by a touch operation during the setting process, wherein the touch operation includes a single-finger touch operation or a multi-fingers touch operation.
In the application, a touch panel is further provided. Referring specifically to a schematic view of the hardware structure of the touch panel shown in
a touch film layer 41, a fingerprint recognition film layer 42 arranged at a light-incident side of the touch film layer 41; the fingerprint recognition film layer 42 may also be arranged on a side other than the light-incident side of the touch film layer 41;
wherein an orthographic projection of the fingerprint recognition film layer 42 on the touch panel coincides with an orthographic projection of the touch film layer 41 on the touch panel. The fingerprint recognition film layer includes a plurality of fingerprint recognition modules arranged in an array. It should be noted that the fingerprint recognition film layer 42 and the touch film layer 41 of the application are both patterned, and the orthographic projections of the two are at least partially overlapped, which in fact means that the fingerprint recognition film layer 42 is arranged on the entire surface of the touch film layer 41. The “arrange” here is only a positional relationship which does not mean that the two must be in direct contact. In fact, an intermediate film layer can also be provided between the two, and the specific film layer relationship can be set according to the design of actual film layer.
In addition, the touch panel further includes a processing chip, a display module (or called a display), a package cover, and the like.
