Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

As shown in fig. 1, the fingerprint identification method of 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, wherein all display areas of the touch screen are provided with fingerprint sensors.
The mobile terminal in this embodiment includes devices such as a smart phone, a tablet computer, a notebook computer, and a smart watch, which are configured with a touch screen. The touch operation may be a single-point touch operation or a multi-point touch operation. In the single-point touch operation, one contact point area between a user and the touch screen is defined, for example, one finger of the user touches the touch screen, and in the multi-point touch operation, a plurality of contact point areas between the user and the touch screen are defined, for example, two fingers of the user simultaneously touch the touch screen.
Wherein, the fingerprint sensor is provided with corresponding sensing units, the number of the sensing units is in direct proportion to the size of the touch screen, and the range can be 103-108Between, when the finger passes through the touch-sensitive screen and conveys fingerprint signal to the induction element, correspond the induction element and carry out charge-discharge, because the line of finger moves back to wood syndrome, the induction element can form the signal of telecommunication that corresponds, according to the difference of signal of telecommunication to form fingerprint image data.
Before this step, the sensing function of the sensing units in all display areas of the touch screen, namely the fingerprint identification function, is in an off state. The reason for this is: the sensing function of the sensing unit is turned off when fingerprint identification is not performed, so that the power consumption of the touch screen can be reduced.
Fig. 2 is a schematic structural diagram of a touch screen of a mobile terminal according to an embodiment of the present invention. As shown in fig. 2, the touch screen of the mobile terminal has a fingerprint sensor under the entire display area O. The display panel of the mobile terminal generally comprises 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 below the touch screen of the mobile terminal. It can be understood that, when the display area of the mobile terminal is the whole front screen of the mobile terminal facing the user, the touch screen of the mobile terminal is the whole front screen.
In the prior art, a fingerprint sensor is generally disposed in a non-display area at the bottom of a mobile terminal for collecting fingerprints, for example, an X area in fig. 2, or a fingerprint sensor is disposed on a rear housing of the mobile terminal for collecting fingerprints. This has the following drawbacks: 1. for an application scene needing to be unlocked by combining a plurality of fingerprint information of a user and the like, one fingerprint is required to be acquired, and the fingerprint identification speed is low; 2. for an application scenario in which a user needs to operate a touch screen to perform fingerprint identification and execute corresponding operations, for example, interactive operations in a game that need to be performed by fingerprint participation cannot be implemented. In the embodiment, the touch operation of the user on the touch screen is detected by adopting the touch screen with the full-screen fingerprint sensor, so that the fingerprint information of the touch operation can be quickly and accurately acquired through the touch screen.

On the basis of the foregoing embodiment, the matching the fingerprint information with the pre-stored fingerprint information may include: and matching the target touch area covered by the touch operation and the corresponding relation between the fingerprint information and the preset touch area and the fingerprint information. The reason why this step is so set is that: the fingerprint is matched by combining two factors of the touch area of the touch operation and the corresponding fingerprint information, so that multiple protection can be performed on the authentication operation, and the safety of user data is ensured. For example, the authentication operation is performed when the touch area of the finger is the set touch area and the finger is the index finger.
