first embodiment

Referring to FIG. 1, FIG. 1 is a flow chart of a method for unlocking interface display provided by an embodiment of the present invention. The method is used for a mobile terminal with a display screen and includes the following steps:

Step 101. Obtain unlocking information input by a user, and authenticate the unlocking information.

When the mobile terminal needs to be unlocked, the user sends unlocking information to the mobile terminal. After obtaining the unlocking information, the mobile terminal matches the unlocking information with preset lock screen information to authenticate the unlocking information. If the unlocking information matches the preset lock screen information successfully, the authentication is passed.

Step 102: After the unlocking information is authenticated, set the lock screen layer to a hidden state, synthesize the preset application layer into frame data through a display service, and send the frame data to the display screen.

Generally speaking, at the moment when the unlock information authentication is passed, the lock screen layer of the display screen is too late to complete redrawing. Composite frame data is sent to the display. Since the lock screen layer can be hidden instantly, the preset application layer output by the display screen is not affected by the lock screen layer at this time, which avoids the situation that the visual change from the lock screen layer to the preset application layer is not smooth.

It should be noted that the preset application layer is the preset application layer of the mobile terminal after the screen is unlocked before the screen is locked, for example, the desktop layer in the default starting state of the mobile terminal, or the user is using the The display layer of an application software, etc.

Step 103, turn on the backlight of the display screen.

The preset application layer is output on the display screen, so that the display screen can be controlled to brighten, and what is presented to the user at this time is the unlocked preset application layer.

In the embodiment of the present invention, the above-mentioned mobile terminal can be any mobile terminal equipped with a display screen, such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short) ), Mobile Internet Device (MID) or wearable device (Wearable Device), etc.

The screen unlocking method according to the embodiment of the present invention includes: acquiring unlocking information input by the user, and authenticating the unlocking information; when the unlocking information is authenticated, setting the lock screen layer to a hidden state, and redrawing the display interface diagram layer; when the display interface layer is redrawn, turn on the backlight of the display screen. In this way, after the user unlocks the mobile terminal, by hiding the lock screen layer, the user can visually avoid the splash screen phenomenon of jumping from the lock screen layer to the unlocked application layer.

second embodiment

Referring to FIG. 2, FIG. 2 is a flowchart of another screen unlocking method provided by an embodiment of the present invention. As shown in FIG. 2, it includes the following steps:

Step 201, acquire unlocking information input by a user.

When the mobile terminal needs to be unlocked, the user sends unlocking information to the mobile terminal.

Step 202, power on the display screen.

After the mobile terminal receives the unlocking information input by the user, at this time, because the display screen is required to respond to the unlocking information, the power supply to the display screen is turned on to provide power support for the display screen to respond to the unlocking operation.

Step 203 , authenticate the unlocking information, and if the authentication is passed, execute step 204 ; otherwise, execute step 206 .

After obtaining the unlocking information, the mobile terminal matches the unlocking information with preset lock screen information to authenticate the unlocking information. If the unlocking information matches the preset lock screen information successfully, the authentication is passed.

Step 204: Redraw the lock screen layer, set the lock screen layer to a hidden state, synthesize frame data through display services, and send the frame data to the display screen.

After the unlock information authentication is passed, the lock screen layer enters the redrawing action. Generally speaking, redrawing actions take an average of 100ms to complete. At this time, the lock screen layer of the display screen is hidden, and the preset application layer is sent to the display screen by synthesizing frame data through the display service (SurfaceFlinger). Since the lock screen layer can be hidden instantly, the preset application layer output by the display screen is not affected by the lock screen layer at this time, and the lock screen layer can be redrawn in the hidden state, avoiding visual changes from the lock screen layer A situation where layer changes are not smooth when applied to a preset.

It should be noted that the default application layer is the application layer displayed on the mobile terminal before the screen is locked. The application layer is memorized and saved at the moment of the lock screen, and is displayed on the display screen after unlocking to help the user reply. Go to the display interface before locking the screen to operate. For example, the preset application layer may be a desktop layer in an initial state saved by default by the mobile terminal, or a display layer of a certain application software that the user is using before the screen is locked, and the like.

Step 205, turn on the backlight of the display screen.

The preset application layer is output on the display screen, so that the display screen can be controlled to brighten, and what is presented to the user at this time is the unlocked preset application layer.

Step 206, disconnect the power supply to the display screen.

When the user fails to unlock, there is no need to change the lock screen layer of the mobile terminal. At this moment, the power supply to the display screen is cut off without any response, which can save power for the mobile terminal.

Optionally, the unlocking information includes user fingerprint information.

Since the user's fingerprint information has the characteristics of easy collection, uniqueness, and difficulty in deciphering, it is convenient for the user to directly input the unlocking information without memorizing it, and the security of the unlocking operation is higher. It can be understood that the unlocking information does not exclude other forms of information, such as character passwords, digital numbers, and the like.

The method for unlocking the screen according to the embodiment of the present invention includes: obtaining the unlocking information input by the user, and authenticating the unlocking information; when the unlocking information is authenticated, redrawing the lock screen layer, and The layer is set to a hidden state, and the frame data is synthesized through the display service, and the frame data is sent to the display screen; the backlight of the display screen is turned on. In this way, after the user unlocks the mobile terminal, by hiding the lock screen layer and redrawing the hidden lock screen layer, the user can visually avoid the splash screen jumping from the lock screen layer to the unlocked application layer Phenomenon.
