At present, the proportion of screens for mobile terminals such as mobile phones and PADs is constantly increasing, and the elimination of independent small devices on the front panel of mobile terminals has become a trend. It is worth noting that fingerprint recognition, as the mainstream device that provides security for mobile terminals today, will be integrated into the screen to form screen fingerprint recognition. Screen fingerprint recognition embeds the fingerprint recognition module at the bottom of the screen, and the user can directly touch the fingerprint recognition area on the screen for fingerprint recognition.

Since the fingerprint recognition area is located on the screen, it is usually required to prompt the user for the location of the fingerprint recognition area, and the fingerprint recognition area is highlighted when prompted, which is in sharp contrast with the system interface. However, traditionally, the fingerprint recognition area is displayed in a fixed size under different interfaces and different screen brightness scenes. However, the size of the fingers of different users is different, and the size of the area touched by the same user is different. When the fingerprint is recognized, when the fingerprint recognition area is smaller than the user's finger, the collected fingerprint is smaller, and the recognition success rate is lower. In addition, when the fingerprint recognition area is larger than the user's finger, the power consumption of the fingerprint recognition area is highlighted, and the area where the fingerprint recognition area is not covered by the user's finger is scattered around the user's finger, which is obviously contrasted with the display of the system interface, resulting in The user's visual experience is poor.

It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

First embodiment

A display method of a fingerprint identification area provided by an embodiment of the present disclosure is described in detail.

Referring to FIG. 1 , a flowchart of a method for displaying a fingerprint identification area in an embodiment of the present disclosure is applied to a mobile terminal having a fingerprint recognition function on a touch screen, and the method includes, for example, steps 101 to 103 as given below. . specific,

Step 101: Detect a click operation of the finger in the fingerprint identification area.

In this embodiment, the touch screen of the mobile terminal has a fingerprint recognition function. In a scenario such as fingerprint entry, fingerprint unlocking, fingerprint payment, fingerprint encryption and decryption, and fingerprint login, the mobile terminal displays the fingerprint identification area on the touch screen. The fingerprint identification area can be displayed differently from the system interface, so that the user can recognize the identification area, which is not limited in detail in the embodiment of the present disclosure, and can be set according to actual conditions.

The finger recognition area is clicked with the finger, and the touch screen of the mobile terminal detects the click operation of the finger in the fingerprint recognition area. Specifically, the touch points of the finger on the touch screen and the touch duration of each touch point can be detected. For example, the touch points 1-10 are detected, wherein the touch duration of the touch points 1-5 is greater than 10 s, the touch duration of the touch points 6-8 is greater than 5 s less than 10 s, and the touch duration of the touch points 9-10 is less than 5 s. The content of the disclosure is not limited in detail, and may be set according to actual conditions.

Step 102: Determine a size of a contact area of the finger with the touch screen.

In this embodiment, after the click operation is detected, the size of the contact area between the finger and the touch screen is determined according to the click operation. Specifically, the size of the contact area may be determined according to the touch point of the finger on the touch screen and the touch duration of each touch point. For example, when the threshold of the touch duration is 5 s, the size of the contact area is determined according to the detected touch points 1-8; when the threshold of the touch duration is 10 s, the size of the contact area is determined according to the detected touch points 1-5. The manner of determining the contact area is not limited in detail in the embodiment of the present disclosure, and may be set according to actual conditions.

Step 103: Adjust a size of the fingerprint identification area and/or display the fingerprint identification area according to a size of a contact area of the finger and the touch screen.

In this embodiment, after determining the size of the contact area between the finger and the touch screen, the size of the fingerprint identification area can be adjusted in real time, and the adjusted fingerprint identification area is displayed. Alternatively, the fingerprint recognition area that matches the contact area may be directly displayed on the touch screen according to the size of the contact area. Specifically, for a user with a large finger, a contact area of a part of the user's finger on the touch screen exceeds the fingerprint recognition area, and the fingerprint recognition area is adjusted to be large, so that the fingerprint recognition area and the finger contact area are matched. For a user with a small finger, the user's finger cannot completely cover the fingerprint recognition area, and some of the fingerprint recognition area is scattered around the user's finger. At this time, the fingerprint recognition area is adjusted to be small, and the fingerprint recognition area is still matched with the finger contact area.

In summary, in the embodiment of the present disclosure, the touch screen of the mobile terminal has a fingerprint recognition function, the mobile terminal detects a click operation of the finger in the fingerprint recognition area, determines the size of the contact area between the finger and the touch screen, and the size of the contact area according to the finger and the touch screen. , adjusting the size of the fingerprint recognition area and/or displaying the fingerprint identification area. Since the mobile terminal dynamically adjusts the size of the fingerprint recognition area, the fingerprint recognition area is adjusted for a user with a larger finger, and a larger area fingerprint can be collected, thereby improving the success rate of fingerprint recognition, and narrowing the fingerprint recognition for a user with a smaller finger. The area reduces the power consumption of the highlighted fingerprint area.

For example, based on the selected boundary values, the fingerprint recognition area is determined to be a rectangle having a length of 2 cm and a width of 1 cm, or the fingerprint recognition area is determined to be a circle having a radius of 1.5 cm. The shape and size of the fingerprint identification area are not limited in detail in the embodiment of the present disclosure, and may be set according to actual conditions.

After the size of the fingerprint identification area is determined, the display is performed according to the determined fingerprint identification area. The mobile terminal can generate a prompt message prompting the user to touch the touch screen within the fingerprint recognition area.

In this embodiment, when the user's finger touches the touch screen in the fingerprint recognition area, the position coordinate value of the touch point of the user's finger on the touch screen is detected. Specifically, a coordinate system on the touch screen is established, and when the user's finger touches the touch screen, the position of each touch point in the coordinate system is detected. For example, the center of the touch screen is the coordinate (0, 0). When the user touches the touch screen, the positions of the touch points in the coordinate system are detected as (100, 0), (150, 0), (0, 50), (0,-50). The embodiment of the present disclosure does not specifically define how to establish a coordinate system, and may be set according to actual conditions.

Optionally, the detection method of the touch point includes at least one of capacitance detection, optical detection, and ultrasonic detection. For example, a touch point is detected according to a change in capacitance of a partial area on the touch screen, or a touch point is detected according to a change in the amount of light received in a partial area on the touch screen. The embodiments of the present disclosure are not limited in detail, and may be set according to actual conditions.

Step 203: Store and update the position coordinate value of the touch point.

Step 204: Determine a size of a contact area of the finger with the touch screen according to a position coordinate value of the touch point.

In this embodiment, after the position coordinates of the touched point are detected, the position coordinate value of each touch point is counted, and the size of the contact area is determined according to the position coordinate value of each touch point. For example, the size of the contact area is determined based on the position coordinate values (100, 0), (150, 0), (0, 50), (0, -50).

Step 205: Adjust a size of the fingerprint identification area and/or display the fingerprint identification area according to a size of a contact area of the finger and the touch screen.

Specifically, as shown in FIG. 3A, the fingerprint identification area 301 is a rectangle, and the fingerprint identification area 301 is a rectangular display. The fingerprint identification area is adjusted to an elliptical shape of the finger contact area. For a user with a large finger, as shown in the left diagram of FIG. 3B, a part of the finger contact area is beyond the fingerprint recognition area, the fingerprint recognition area 301 is enlarged to the fingerprint recognition area 302, and the contact area beyond the fingerprint recognition area is converted by the display touch screen interface. To display the fingerprint identification area. For the user with a small finger, as shown in the right figure of FIG. 3B, a part of the fingerprint identification area is scattered around the user's finger, and the fingerprint identification area 301 is reduced to the fingerprint identification area 303, and the display area outside the fingerprint identification area, that is, the original A fingerprint recognition area that is scattered around the finger is displayed as a touch screen interface.
