Detailed ways

In order to make the purpose, features and advantages of the invention of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The embodiments described above are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.

An embodiment of the present application provides a method for displaying an optical fingerprint icon, and the method for displaying an optical fingerprint icon is applied to an electronic device, and the electronic device may be a personal computer, a smart phone, a tablet computer, or the like.

Referring to FIG. 1, the method for displaying an optical fingerprint icon in the embodiment of the present application mainly includes the following steps 101 to 103:

Step 101 , detect the current application scenario.

Not all application scenarios require the use of fingerprint recognition. For example, users may not need fingerprint recognition when listening to music, reading or watching videos. In some application scenarios, such as unlocking, locking the screen, or payment applications, Fingerprinting or verification possible. Therefore, in this embodiment of the present application, the detection of the current application scenario needs to be done first.

Step 102 , if the current application scenario is that the fingerprint identification application has been entered, notify the display module to display the optical fingerprint icon by means of fast communication.

When the current application scenario has entered the fingerprint recognition application, for example, fingerprint lock screen, unlock, etc., it means that the optical fingerprint icon needs to be displayed on the user interface as quickly as possible. Different from the prior art that needs to notify the display module to display the optical fingerprint icon through complex paths such as the user interface layer, the technical solution of the present application is to notify the display module to display the optical fingerprint icon through fast communication when the current application scenario has entered the fingerprint identification application.

As an embodiment of the present application, step 102 can be completed through the following steps 1021 and 1022:

Step 1021: If the current application scenario is that the fingerprint identification application has been entered, the user interface layer draws an optical fingerprint icon.

In the system framework of most terminals, the user interface (User Interface, UI) layer is the uppermost layer in the system framework, directly facing the user. In this embodiment of the present application, when the current application scenario has entered the fingerprint identification application, the user interface layer may draw an optical fingerprint icon.

Step 1022 , the fingerprint driving module notifies the display module to display the optical fingerprint icon drawn by the user interface layer through the underlying fast channel.

It should be noted that the time for the user interface layer to draw the optical fingerprint icon is negligible. Therefore, whether it is the prior art or the technical solution of the present application, the drawing of the optical fingerprint icon itself and the time it takes are not the same as the technical solution of the present application. The differences between the technical solutions are described as follows:

The process of displaying an optical fingerprint icon in the prior art is shown in FIG. 2, and the specific process is: the user presses the screen to generate a screen pressing event, the screen pressing event is reported to the user interface layer by the fingerprint driver module, and the user interface layer draws the optical fingerprint icon. , and then pass the drawn optical fingerprint icon to the display module for display, after that, wait for the display module to display the optical fingerprint icon. In the embodiment of the present application, the fingerprint driving module no longer interacts with the user interface layer, but directly informs the display module to display the optical fingerprint icon drawn by the user interface layer, as shown in FIG. 3 . Since the interaction between the fingerprint driving module and the display module does not pass through the user interface layer, the interaction time and path between the fingerprint driving module and the user interface layer are saved. The time to display the optical fingerprint icon in advance. For example, if the interaction time between the fingerprint driver module and the user interface layer is 80ms (milliseconds), then under the same conditions, the technical solution of the present application can be displayed 80ms earlier than the solution of the prior art Optical fingerprint icon.

If the optical fingerprint icon is still displayed for a long time when the user does not press the screen for a long time, it will bring a bad experience to the user. Therefore, in the above-mentioned embodiment of the present application, the method for displaying an optical fingerprint icon further includes: the user interface layer sends the drawn optical fingerprint icon to the display module; when no screen pressing event is detected, the display module displays the drawn optical fingerprint icon by the user interface layer. The optical fingerprint icon is hidden. Correspondingly, the fingerprint driving module in the above step 1022 notifies the display module to display the optical fingerprint icon drawn by the user interface layer through the bottom fast channel, which may be: the fingerprint driving module detects whether a screen pressing event occurs, and if a screen pressing event occurs, the fingerprint driving module Through the user interface layer, the display module is directly notified to display the hidden optical fingerprint icon. Since both the fingerprint driver module and the display module belong to the bottom layer, the direct communication between the fingerprint driver module and the display module is much faster than the communication between the fingerprint driver module and the display module via the user interface layer, that is, the time consumption is shorter.

Step 103: If the current application scenario is to enter the fingerprint identification application, notify the display module in advance to display the optical fingerprint icon.

Considering that the application scenario is about to enter the fingerprint identification application, it means that the fingerprint identification application will be entered with a high probability. Therefore, the display module is notified to display the optical fingerprint icon in advance, that is, before the current application scenario has entered the fingerprint identification application. Compared with the existing technology It's still a lot faster to only show the optical fingerprint icon when entering the fingerprint recognition app.

In order to realize the technical solution of step 103, the method of the above embodiment of the present application further includes: the user interface layer draws an optical fingerprint icon; and the user interface layer sends the drawn optical fingerprint icon to the display module to be saved by the display module. Correspondingly, if the current application scenario is about to enter the fingerprint recognition application, the display module is notified in advance to display the optical fingerprint icon in the following manner. That is, if the current application scenario is to enter the fingerprint recognition application, the display module is notified in advance to display The optical fingerprint icon includes: if the current application scenario is to enter the fingerprint identification application, the user interface layer sends a notification to the display module to display the optical fingerprint icon; after the display module receives the notification to display the optical fingerprint icon, the current The saved optical fingerprint icon is displayed before entering the fingerprint recognition application in the application scenario of the current application scenario. In this way, before the current application scenario enters the fingerprint recognition application, the user can see the optical fingerprint icon drawn by the user interface layer and saved by the display module.

However, in the current application scenario, the fingerprint identification application is delayed and the drawn optical fingerprint icon is displayed, which will bring a bad experience to the user. Therefore, in this embodiment of the present application, the above-mentioned method further includes: starting a preset condition monitoring, if the preset condition reaches a preset threshold and the current application scene has not yet entered the fingerprint identification application, the displayed optical The fingerprint icon is hidden until the current application scene enters the fingerprint recognition application and the saved optical fingerprint icon is displayed again. For example, if the current application scenario is about to enter the fingerprint recognition application, start the timer to start timing. If the timer reaches the preset time threshold and the current application scenario has not yet entered the fingerprint recognition application, the displayed optical fingerprint icon will be displayed. Hide until the current application scene enters the fingerprint recognition application and the saved optical fingerprint icon is displayed again; or, activate the sensor device, for example, activate the built-in pose sensor of the terminal, if the position or posture of the terminal reaches the preset position or gesture data, but the current application scene has not yet entered the fingerprint recognition application, the displayed optical fingerprint icon is hidden until the current application scene enters the fingerprint recognition application and the saved optical fingerprint icon is displayed again.

It can be seen from the optical fingerprint icon display method shown in the above example of FIG. 1 that, on the one hand, if the current application scenario has entered the fingerprint recognition application, the display module is notified to display the optical fingerprint icon through the fast communication method. Compared with the prior art, the optical fingerprint icon can be quickly displayed when the current application scenario has entered the fingerprint recognition application; Compared with the prior art, it is much faster to display the optical fingerprint icon when entering the fingerprint identification application. In conclusion, no matter what the situation is, the technical solution of the present application can quickly display the optical fingerprint icon compared with the prior art, thereby Meet the needs of application scenarios that quickly display optical fingerprint icons.

Not all application scenarios require the use of fingerprint recognition. For example, users may not need fingerprint recognition when listening to music, reading or watching videos. In some application scenarios, such as unlocking, locking the screen, or payment applications, Fingerprinting or verification possible. Therefore, in this embodiment of the present application, the detection module 401 first needs to perform the detection of the current application scenario.

The first notification module 402 is configured to notify the display module 404 to display the optical fingerprint icon by means of fast communication if the current application scenario is that the fingerprint identification application has been entered.

When the current application scenario has entered the fingerprint recognition application, for example, fingerprint lock screen, unlock, etc., it means that the optical fingerprint icon needs to be displayed on the user interface as quickly as possible. Different from the prior art, which needs to notify the display module 404 to display the optical fingerprint icon through a complex path such as the user interface layer, the technical solution of the present application is that when the current application scenario has entered the fingerprint recognition application, the first notification module 402 notifies by fast communication. The display module 404 displays the optical fingerprint icon.

The second notification module 403 is configured to notify the display module 404 in advance to display the optical fingerprint icon if the current application scenario is to enter the fingerprint identification application.

Considering that the application scenario will enter the fingerprint identification application, it means that the fingerprint identification application will be entered with a high probability. Therefore, if the current application scenario is to enter the fingerprint identification application, the second notification module 403 in advance. That is, the current application scenario has not yet entered the fingerprint identification application. The display module 404 is notified to display the optical fingerprint icon before the identification application, which is still much faster than displaying the optical fingerprint icon when entering the fingerprint identification application in the prior art.

In this embodiment of the present application, when the current application scenario has entered the fingerprint identification application, the user interface layer may draw an optical fingerprint icon.

The fingerprint driving module 502 is configured to notify the display module to display the optical fingerprint icon drawn by the user interface layer through the underlying fast channel.

It should be noted that the time for the user interface layer to draw the optical fingerprint icon is negligible. Therefore, whether it is the prior art or the technical solution of the present application, the drawing of the optical fingerprint icon itself and the time it takes are not the same as the technical solution of the present application.

Since the interaction between the fingerprint driving module 502 and the display module 404 does not pass through the user interface layer, the interaction time and path between the fingerprint driving module 502 and the user interface layer are omitted. This saved time is the difference between the present application and the prior art. solution, the time that the optical fingerprint icon can be displayed in advance. For example, if the interaction time between the fingerprint driving module 502 and the user interface layer is 80ms (milliseconds), then under the same conditions, the technical solution of the present application is compared with the solution of the prior art The optical fingerprint icon can be displayed 80ms in advance.
