The input operation of the user on the display screen comprises touch operation input on the display screen or operation which is positioned above the display screen and is separated from the display screen by a preset distance.

For example, in some embodiments, the display screen is a touch display screen, and the input operation of the user on the display screen may include a touch operation performed by at least one finger of the user on the display screen.

Further, the determining, according to the sliding track of the input operation of the user on the display screen, that the track pattern corresponding to the sliding track is the unlocking pattern may include determining, according to each coordinate position of the input operation of the user on the display screen, the sliding track, and determining that the track pattern corresponding to the sliding track is the unlocking pattern.

Wherein, when the input operation is an input operation of the non-contact display screen 10, the respective coordinate positions of the input operation are the respective coordinate positions of the projection on the display screen 10.

Therefore, in the present application, the input operation performed by the at least one finger on the display screen includes a touch operation input on the display screen or an operation located above the display screen and spaced from the display screen by a preset distance, and the input operation may be an operation input at any position of the display screen.

Obviously, the object to be unlocked in the present application may also be an operation that needs to be performed through authentication, for example, operations such as file deletion, access, transfer and the like that need to be performed through authentication.

Therefore, in the application, the unlocking pattern input by the user and the fingerprint information input by each line segment of the execution unlocking pattern are obtained and compared with the preset unlocking pattern and the preset fingerprint information string, and the unlocking is performed when the unlocking pattern and the preset fingerprint information string are matched, so that the unlocking safety is improved.

Wherein, the fingerprint identification sensor 1 corresponding to the first point light source 41 is used for receiving the target light signal a1 to identify/collect fingerprint information. The second point light source 42 emits a second light signal b providing display brightness for the display screen 10. The wavelength of the first optical signal a and the wavelength of the second optical signal b are different.

Specifically, the target light signal a1 carries fingerprint information. The target optical signal a1 is reflected by the fingerprint grain F to the fingerprint identification sensor 1, the fingerprint identification sensor 1 receives the target optical signal a1 and converts the target optical signal a1 into a target electrical signal, and the processor stores and identifies the fingerprint information of the fingerprint grain F according to the target electrical signal.

The refractive index n1 (e.g., n1 is 1.55) of the ridge F2 is closer to the refractive index n3 (e.g., n3 is 1.5 for normal glass) of the touch substrate 2 than the refractive index n2 (e.g., n2 is 1) of air, and thus the intensity of the reflected light of the first optical signal a at the surface 211 of the touch substrate 2 is greater than the intensity of the reflected light at the surface of the ridge F2. Therefore, in the fingerprint image acquired by the fingerprint recognition sensor 1, the brightness of the image area corresponding to the valley F1 is strong, and the brightness of the image area corresponding to the ridge F2 is weak. Of course, in other embodiments, the fingerprint pattern F may be located on the touch substrate 2 and spaced apart from the touch substrate 2, and the fingerprint image may be obtained by using the difference of the reflection intensity of the light by the valleys F1 and the ridges F2 of the fingerprint pattern F.
