At present, a hole is dug in the whole cover plate glass, and a fingerprint sensor is arranged in the hole, so that the strength of the whole cover plate glass is reduced, and the design of the appearance of a terminal is limited.
In order to solve the above problem, in this embodiment, the fingerprint sensor may be disposed under the touch screen, and the terminal may detect a touch position of a finger; when the touch position of the finger is in the touch response area, controlling a fingerprint sensor to perform fingerprint scanning on a fingerprint acquisition area to obtain fingerprint information of the finger; therefore, the touch control and fingerprint acquisition functions are integrated in the touch screen, cover plate glass is not affected, the appearance design of the terminal is facilitated, the touch response area is located in the fingerprint acquisition area, the area of the touch response area is smaller than that of the fingerprint acquisition area, when the terminal detects that the touch position of a finger is located in the touch response area, the sufficient effective area is arranged in the fingerprint acquisition area where the touch response area is located to acquire fingerprint information, and complete fingerprint information can be acquired.
Fig. 1 is a flowchart illustrating a fingerprint collection method according to an exemplary embodiment, where as shown in fig. 1, the fingerprint collection method is used in a device such as a terminal, and includes the following steps 101 and 102:
in step 101, a touch position of a finger is detected.
In step 102, when the touch position of the finger is in the touch response area, controlling the fingerprint sensor to perform fingerprint scanning on a fingerprint acquisition area to obtain fingerprint information of the finger; wherein the touch response area is located in the fingerprint acquisition area, and the area of the touch response area is smaller than that of the fingerprint acquisition area.
Here, fingerprint sensor is the key device that realizes fingerprint automatic acquisition, and this disclosure adopts the fingerprint collection scheme in the face, sets up fingerprint sensor under the touch-sensitive screen of terminal, and this fingerprint sensor can gather the fingerprint information in the fingerprint collection region on the touch-sensitive screen, and this fingerprint collection region is the region that this fingerprint sensor can gather fingerprint information promptly. For example, fig. 2 is a schematic diagram illustrating a terminal capable of implementing a fingerprint collection method according to an exemplary embodiment, and as shown in fig. 2, a fingerprint sensor (not shown in the figure) is disposed under the touch screen 20 of the terminal 2, and the fingerprint sensor is capable of collecting fingerprint information in a fingerprint collection area 201.
Here, the touch screen of the terminal may detect a touch position of a finger of a user, and when the terminal needs to collect fingerprint information for user identification or unlocking, decryption, etc., the user may place the finger in a touch response area of the touch screen, and at this time, the touch screen may detect the finger touch position of the finger, for example, an intersection of two adjacent frames on the touch screen may be set as an origin, one of the two adjacent frames is located on an x-axis, and an adjacent frame in a direction perpendicular to the x-axis is set as a y-axis, and the finger touch position detected by the touch screen may be coordinates (x1, y1), if, as shown in fig. 2, the coordinates (x1, y1) are in the touch response area 202, since the touch response area 202 is within the fingerprint collection area 201 and belongs to a part of the fingerprint collection area 201, when the touch screen detects the finger touch position in the touch response area 202, most fingerprints of the finger are in the fingerprint acquisition area 201, and when the terminal controls the fingerprint sensor to perform fingerprint scanning on the fingerprint acquisition area 201, enough effective areas in the fingerprint acquisition area 201 obtain relatively complete fingerprint information.
According to the embodiment, the fingerprint sensor can be arranged below the touch screen, and the terminal can detect the touch position of a finger; when the touch position of the finger is in the touch response area, controlling a fingerprint sensor to perform fingerprint scanning on a fingerprint acquisition area to obtain fingerprint information of the finger; therefore, the touch control and fingerprint acquisition functions are integrated in the touch screen, cover plate glass is not affected, the appearance design of the terminal is facilitated, the touch response area is located in the fingerprint acquisition area, the area of the touch response area is smaller than that of the fingerprint acquisition area, when the terminal detects that the touch position of a finger is located in the touch response area, the sufficient effective area is arranged in the fingerprint acquisition area where the touch response area is located to acquire fingerprint information, and complete fingerprint information can be acquired.
In a possible implementation manner, in the fingerprint acquisition method, the boundary of the touch response area does not overlap with the boundary of the fingerprint acquisition area.
Here, as shown in fig. 2, the boundary of the touch response area 202 does not overlap with the boundary of the fingerprint collection area 201, so that the fingerprint collection area 201 includes the touch response area 202 and its peripheral area. When the touch screen detects that the touch position of the finger is in the touch response area 202, the contact position of the finger and the touch screen is in the touch response area 202, and the area where the fingerprint of the finger is located is necessarily in the touch response area 202 and the peripheral area thereof, so that when the fingerprint acquisition area 201 is scanned, enough effective area in the fingerprint acquisition area 201 can obtain more complete fingerprint information.
According to the embodiment, the boundary of the touch response area and the boundary of the fingerprint acquisition area are not overlapped, and the sufficient effective area in the fingerprint acquisition area can be ensured to acquire more complete fingerprint information when the touch position of the finger is in the touch response area.
In a possible implementation manner, in the fingerprint acquisition method, the touch response area is located in the middle of the fingerprint acquisition area.
Here, as shown in fig. 2, the touch response area 202 may be located in the middle of the fingerprint collection area 201, when the touch screen detects that the touch position of the finger is in the touch response area 202, the contact position of the finger and the touch screen is in the touch response area 202, and since the touch response area 202 is located in the middle of the fingerprint collection area 201, the area where the fingerprint of the finger is located is necessarily in the fingerprint collection area 201, which ensures that when the fingerprint collection area 201 is scanned, there is enough effective area in the fingerprint collection area 201 to obtain more complete fingerprint information.
The touch response area in the embodiment is located in the middle of the fingerprint acquisition area, so that when the touch position of a finger is located in the touch response area, the fingerprint acquisition area has enough effective area to acquire more complete fingerprint information.
In a possible implementation, the fingerprint acquisition method further includes the following step a 1.
In step a1, when it is detected that fingerprint collection is required, a prompt pattern is displayed in the touch response area, where the prompt pattern is used to prompt the position touched by the finger when fingerprint collection is performed.
Here, the terminal may detect that fingerprint acquisition is needed to unlock the fingerprint when the terminal detects that the user picks up the mobile phone in the screen-off state, or the terminal may detect that fingerprint acquisition is needed to decrypt the fingerprint when the terminal detects that a file or an application icon that needs to decrypt the fingerprint is on the current interface in the screen-on state.
Here, the touch response area is arranged at an appointed position in the terminal touch screen, when the terminal detects that fingerprint collection is needed, the terminal can display a prompt pattern on the touch response area to prompt a user of the position touched by a finger when the fingerprint collection is needed, so that the user can know the position touched by the finger when the fingerprint collection is needed, and further the fingerprint can be accurately input in the touch response area.
For example, when the terminal is in a screen-off state, it may be detected that unlocking is required, that is, it is detected that fingerprint acquisition is required, at this time, the terminal may control the touch response area to be in a screen-on state and other areas to be in a screen-off state, and thus, the user may be prompted to perform fingerprint input in the area in the screen-on state by displaying the prompt pattern. Or, when the terminal is in a bright screen state and detects that a user needs to open a certain file or application with encrypted fingerprint, the terminal detects that fingerprint decryption is needed, namely fingerprint acquisition is needed, at the moment, the terminal can display a fingerprint pattern or other patterns in the fingerprint acquisition area, and thus, the user can be prompted to perform fingerprint input in the area where the prompt pattern is located.
According to the embodiment, when the condition that fingerprint collection is needed is detected, the prompt pattern is displayed in the touch response area, the position touched by the finger when the fingerprint collection is carried out is prompted, the user can conveniently identify the position touched by the finger when the fingerprint collection is carried out, and then the fingerprint is accurately input in the touch response area.
In a possible implementation, the fingerprint acquisition method further includes the following steps a2 and A3.
In step a2, fingerprint recognition is performed based on the fingerprint information of the finger.
In step a3, when fingerprint recognition is successful, the prompt pattern displayed in the touch response area is cancelled.
Here, the terminal controls the fingerprint sensor to perform fingerprint scanning on the fingerprint acquisition area, after the fingerprint information of the finger is obtained, fingerprint identification can be performed according to the fingerprint information of the finger, if the fingerprint identification fails, a prompt pattern can be continuously displayed in the touch response area to prompt a user to continuously input the fingerprint information for fingerprint identification, if the fingerprint identification succeeds, the user is indicated to have performed fingerprint input and the fingerprint identification succeeds, at the moment, the terminal does not need to display the prompt pattern to prompt the position of the fingerprint input, so the terminal can cancel the prompt pattern displayed in the touch response area, so that when the fingerprint identification is not needed, the prompt pattern can not be displayed, the shielding of the prompt pattern is avoided, and the user can use the terminal conveniently.
According to the embodiment, when the fingerprint identification is successfully carried out according to the fingerprint information of the finger, the prompt pattern displayed in the touch response area is cancelled, so that the shielding of the prompt pattern is avoided, and the user can use the terminal conveniently.
The implementation is described in detail below by way of several embodiments.
Fig. 3 is a flowchart illustrating a fingerprint acquisition method according to an exemplary embodiment, where the method may be implemented by a terminal or the like, as shown in fig. 3, and includes steps 301 and 310.
In step 301, when it is detected that fingerprint collection is required, a prompt pattern is displayed in the touch response area, where the prompt pattern is used to prompt a position touched by a finger when fingerprint collection is required.
In step 302, a touch position of a finger is detected.
In step 303, when the touch position of the finger is in the touch response area, the fingerprint sensor is controlled to perform fingerprint scanning on a fingerprint acquisition area to obtain fingerprint information of the finger.
The touch response area is located in the fingerprint acquisition area, the area of the touch response area is smaller than that of the fingerprint acquisition area, the boundary of the touch response area is not overlapped with that of the fingerprint acquisition area, and the touch response area is located in the middle of the fingerprint acquisition area.
In step 304, fingerprint recognition is performed according to the fingerprint information of the finger.
In step 305, when the fingerprint identification is successful, the prompt pattern displayed in the touch response area is cancelled.
