It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Figure 1 shows a flow chart of a fingerprint identification method for a mobile terminal provided by an embodiment of the present invention. The method of this embodiment can be executed by a fingerprint identification device for a mobile terminal, which can be implemented by means of hardware and/or software. To achieve, the device can be set inside the mobile terminal as a part of the mobile terminal.

As shown in Figure 1, a fingerprint identification method for a mobile terminal provided in this embodiment includes the following steps:

Step 101. Detecting a touch operation acting on a touch screen of a mobile terminal, where the entire display area of the touch screen has a fingerprint sensor.

The mobile terminals described in this embodiment include devices equipped with touch screens, such as smart phones, tablet computers, notebooks, and smart watches. The touch operation may be a single-point touch operation or a multi-point touch operation. In the single-touch operation, there is one contact point area between the user and the touch screen, for example, one finger of the user touches the touch screen; in the multi-touch operation, there are multiple contact point areas between the user and the touch screen, for example, two fingers of the user touch the touch screen. Touch the touch screen with two fingers at the same time.

Among them, there are corresponding sensing units on the fingerprint sensor, the number of which is proportional to the size of the touch screen, and the range can be between 10 ³ -10 ⁸ . When the finger passes through the touch screen to transmit the fingerprint signal to the sensing unit, the corresponding sensing unit is charged. Discharge, due to the texture of the finger, the sensing unit will form a corresponding electrical signal, and the fingerprint image data will be formed according to the difference of the electrical signal.

Before this step, the sensing function of the sensing unit in the entire display area of the touch screen, that is, the fingerprint recognition function is in an off state. The reason for this setting is: to turn off the sensing function of the sensing unit when no fingerprint recognition is performed, so as to reduce the power consumption of the touch screen.

FIG. 2 shows a schematic structural diagram of a touch screen of a mobile terminal provided by an embodiment of the present invention. As shown in FIG. 2 , there is a fingerprint sensor under the entire display area O of the touch screen of the mobile terminal. The display panel of the mobile terminal generally includes a substrate, a sensing conductive layer, a fingerprint sensor layer and a touch screen from bottom to top. In this embodiment, a fingerprint sensor layer is laid under the touch screen of the mobile terminal. It can be understood that when the display area of the mobile terminal is the entire front screen of the mobile terminal facing the user, the touch screen of the mobile terminal is the entire front screen.

In the prior art, generally a fingerprint sensor is set on the non-display area at the bottom of the mobile terminal to collect fingerprints, such as the X area in Figure 2, or a fingerprint sensor is set on the rear shell of the mobile terminal to collect fingerprints . This has the following disadvantages: 1. For application scenarios that need to combine multiple fingerprint information of the user for unlocking and other operations, it is necessary to collect one fingerprint and one fingerprint, and the fingerprint recognition speed is relatively slow; 2. For users who need to operate the touch screen to perform fingerprinting It is impossible to identify the application scenarios that perform corresponding operations, such as interactive operations that require fingerprints in games. In this embodiment, a touch screen with a full-screen fingerprint sensor is used to detect a user's touch operation on the touch screen, so that the fingerprint information of the touch operation can be acquired quickly and accurately through the touch screen.

Step 102: Determine that the area covered by the touch operation is the target touch area, enable the fingerprint recognition function of the target touch area, and obtain the fingerprint information corresponding to the touch operation, except for the target touch area in the touch screen The fingerprint recognition function of the area is turned off.

After the touch operation acting on the touch screen of the mobile terminal is detected, the area covered by the touch operation is located, and the area covered by the touch operation is determined as the target touch area. The reason for this step is to determine the target touch area, and only enable the fingerprint recognition function of the sensing unit in the target touch area, and the fingerprint recognition function of the sensing units in other non-target touch areas is in a closed state, which can be accurately realized. On the basis of acquiring the fingerprint information corresponding to the touch operation, the power consumption of the sensing unit of the touch screen is reduced.

Step 103, identifying the fingerprint information.

The fingerprint identification method of the mobile terminal provided in this embodiment detects a touch operation acting on the touch screen of the mobile terminal, and the entire display area of the touch screen is covered by the fingerprint sensor, locates the touch operation, and determines the location of the touch operation. The covered area is the target touch area, and the fingerprint identification function of the target touch area is enabled, and the fingerprint information corresponding to the touch operation is obtained, and the fingerprint identification function of the area other than the target touch area in the touch screen is turned off, Identifying the fingerprint information can realize the identification of the fingerprint information through the touch screen of the mobile terminal, and reduce the power consumption of the touch screen of the mobile terminal.

On the basis of the above embodiments, the identifying the fingerprint information may include: matching the fingerprint information with pre-stored fingerprint information; if the matching is successful, performing a corresponding authentication operation. Wherein, the authentication operation includes unlocking, payment, or login, etc., and also includes interactive information authentication operations in game applications. For example, in a game application scenario, the user can open the door by touching the door mark on the door. When the touch screen of the mobile terminal acts on the touch operation of the door sign, the fingerprint recognition function of the target touch area where the touch operation is located is turned on. When the fingerprint information of the touch operation is the matching fingerprint information, the operation of opening the door is performed.

On the basis of the above embodiments, the matching of the fingerprint information with the pre-stored fingerprint information may include: matching the target touch area covered by the touch operation and the fingerprint information with the preset touch area and fingerprint information The corresponding relationship is matched. The reason for this step is to match the fingerprints by combining the two factors of the touch area of the touch operation and the corresponding fingerprint information, so as to provide multiple protections for the authentication operation and ensure the security of user data. For example, the authentication operation is performed only when the touch area of the finger is the set touch area and the finger is the index finger.

On the basis of the above embodiments, the fingerprint sensor includes one or more of an optical fingerprint sensor, an ultrasonic fingerprint sensor or a semiconductor fingerprint sensor, preferably a semiconductor fingerprint sensor.
