For convenience of description, the devices mentioned above are collectively referred to as mobile terminals. The embodiments of the present invention are described in detail below.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart diagram of a method for controlling a bright screen according to an embodiment of the present invention, which is applied to a mobile terminal provided with a fingerprint identification area, where the fingerprint identification area is provided with a physical button and a fingerprint sensor, as shown in FIG. As shown, the present bright screen control method includes:

S101. The mobile terminal wakes up the shift when detecting a touch operation for the fingerprint sensor. The system framework of the mobile terminal is the Framwork layer basic service and the display screen.

Wherein, when the user touches the fingerprint sensor, the fingerprint sensor can detect the change of the capacitance, so the fingerprint sensor can detect the touch operation of the user according to the change of the capacitance. The system Framwork layer basic service of the mobile terminal includes various kernel services of the Android system of the mobile terminal, such as a power management service PMS.

S102. The mobile terminal, when detecting a pressing operation for the physical button, illuminates a backlight of the display screen, and displays a system desktop or an application interface on the display screen.

The system desktop is the main control interface of the mobile terminal, and the application interface is the function interface of the application.

In one possible example, the Framework layer basic service includes a power management service PMS; the mobile terminal illuminates a backlight of the display screen, including:

The mobile terminal notifies the PMS to illuminate the backlight of the display screen.

The backlight is a backlight, and the backlight can be disposed directly under the display screen or on the side of the display screen. The specific position of the backlight is not limited in the present invention.

In one possible example, the mobile terminal displays a system desktop or an application interface on the display screen, including:

The mobile terminal displays a system desktop or an application interface on which the preset lock screen interface after the transparent processing is superimposed on the display screen.

In this possible example, the method further includes:

When the touch operation for the fingerprint sensor is detected, the preset lock screen interface is transparently processed, and a fingerprint image is acquired, and a fingerprint authentication operation is performed on the fingerprint image to generate an authentication knot. fruit;

After the system desktop or the application interface of the preset lock screen interface after the transparent processing is superimposed, the method further includes:

When the authentication result is that the authentication is successful, the preset lock screen interface after the transparent processing is removed.

In this possible example, the method further includes:

When the touch operation for the fingerprint sensor is detected, the preset lock screen interface is transparently processed;

Obtaining a fingerprint image, performing a fingerprint authentication operation on the fingerprint image to generate an authentication result;

When it is detected that the authentication result is that the authentication is successful, the transparent locked preset screen is removed.

It can be seen that in the possible example, in the case that the user quickly presses the physical button, the mobile terminal may also remove the lock screen interface in the future. In this case, the mobile terminal transparently processes the touch operation of the user for the fingerprint sensor. Presetting the lock screen interface, obtaining a fingerprint image, performing a fingerprint authentication operation on the fingerprint image to generate an authentication result, and detecting the authentication after displaying the system desktop or the application interface of the preset lock screen interface after the transparent processing is superimposed The result is that the transparent lock processing preset screen is removed when the authentication is successful. Since the mobile terminal generates the authentication result and removes the transparently processed preset lock screen interface when the authentication result is successful, the operation duration is extremely short, generally only for the duration of the millisecond, and the user sees the transparent After the system desktop or the application interface determines the duration of the operation interface, the duration of the operation interface is generally greater than the duration of the millisecond. Therefore, the superimposed preset lock screen interface does not substantially affect the user from seeing the transparent interface to operating the interface. The process has a substantial impact. For the user, the mobile terminal actually implements a rapid unlocking, which is beneficial to improving the brightness of the mobile terminal in the fingerprint unlocking scene and improving the user's fingerprint unlocking experience.

It can be seen that, in the possible example, in the case that the user normally presses the physical button, the mobile terminal may have sufficient time to complete the acquisition of the fingerprint image, generate the authentication result, and detect the operation of removing the preset lock screen interface when the authentication is successful. In the case that the mobile terminal is displayed on the display screen directly after the screen is bright, the system desktop or the application interface without the transparent preset lock screen interface is superimposed, and the user can operate the interface content of the display screen at any time after seeing the bright screen. It is beneficial to improve the brightness speed of the mobile terminal in the fingerprint unlocking scene and improve the user's fingerprint unlocking experience.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of another bright screen control method according to an embodiment of the present invention, which is applied to a mobile terminal provided with a fingerprint identification area, The fingerprint recognition area is provided with a physical button and a fingerprint sensor.

S202. The mobile terminal, when detecting a pressing operation for the physical button, illuminates a backlight of the display screen, and displays a system desktop or application on the display screen that is superimposed with a transparent locking preset screen interface. interface.

S203. The mobile terminal removes the preset lock screen interface after the transparent processing when the authentication result is that the authentication result is successful.

It can be seen that, in the embodiment of the present invention, in the case that the user quickly presses the physical button, the mobile terminal may also remove the lock screen interface in the future. In this case, when the mobile terminal detects the touch operation of the user for the fingerprint sensor, Transparently processing the preset lock screen interface, and acquiring a fingerprint image, and performing a fingerprint authentication operation on the fingerprint image to generate an authentication result, and after displaying the system desktop or the application interface of the preset lock screen interface superimposed with the transparent processing, when detecting When the authentication result is successful, the transparent lock screen is removed. Since the mobile terminal generates the authentication result and removes the transparently processed preset lock screen interface when the authentication result is successful, the operation duration is extremely short, generally only for the duration of the millisecond, and the user sees the transparent Determine the operating community after the system desktop or application interface The duration of the face is generally greater than the duration of the millisecond. Therefore, the superimposed preset lock screen interface does not substantially affect the user from seeing the transparent interface to the process of operating the interface. In other words, the mobile terminal actually implements a kind of rapid unlocking, which is beneficial to improving the brightness speed of the mobile terminal in the fingerprint unlocking scene and improving the user's fingerprint unlocking experience.

FIG. 3 is a schematic flowchart of another method for controlling a bright screen according to an embodiment of the present disclosure, which is applied to a mobile terminal provided with a fingerprint identification area, and the method is the same as the embodiment shown in FIG.
