Description

Terminal and display control method

technical field

The present invention relates to the technical field of display control, in particular, to a terminal and a display control method.

Background technique

In related technologies, when a certain fixed brightness value is set for the screen brightness of the terminal, the brightness can only be changed through manual adjustment. Even the "automatic brightness adjustment" function that comes with the terminal can only make the screen brightness change as the environment changes, and it obviously cannot change automatically in the same environment.

With the increasing screen size of mobile terminals (5.0 inches, 5.7 inches, 7.0 inches and even 10.0 inches), more and more content can be displayed on the same screen, and the visualization area is getting larger and larger. It is also easier to be peeped by other users from the side of the terminal or from a distance, especially the content originally set up by the user through passwords, fingerprints, etc. After the user unlocks the content, the content can be viewed by other users, thus greatly Reduced user security. Especially when the user's terminal is kept at the same brightness all the time, no matter whether it is the content with preset permissions or not, it will be displayed on the screen of the terminal with the same visibility, regardless of whether the user manually blocks the content , obviously will undoubtedly bring a lot of trouble to users, and even make the original permission restrictions useless.

Therefore, a new display control technology is needed, which can automatically adjust the display brightness of the terminal according to the setting of the authority, thereby limiting the screen visibility of the terminal and ensuring the privacy of the user.

Peeping from the screen of the terminal improves the security of terminal use. The preset permissions here may include the setting of one or more of passwords, fingerprints, patterns, gesture graphics, and the like.

In the above technical solution, preferably, the step of judging whether there is a corresponding preset authority on the target page includes: judging whether the application where the target page is located and/or the content contained in the target page exists Default permissions. In this technical solution, in the first case, when an application has a preset permission (such as the startup password of the application, etc.), it is determined that any application program interface in the application has a corresponding preset permission ; In the second case, when the content contained in a certain application program interface has preset permissions (such as encrypted text messages in the application "SMS"), it is determined that the application program interface has corresponding preset permissions; In this case, if the application program and the content contained in the application program interface have preset permissions, it is determined that the target page has preset permissions. By setting the permission of the application program, it is beneficial to simplify the permission setting process; and by setting the permission of the content of the page, it is beneficial to realize more precise permission control, so as to realize more accurate screen brightness control.

In the above technical solution, preferably, the step 204 further includes: if there is a corresponding preset permission on the target page, further obtaining the level of the preset permission, and displaying the A target page; wherein, the higher the level, the lower the brightness. In this technical solution, by grading the brightness adjustment, the more important pages are more difficult to view, ensuring higher security. However, due to the adjustment of the screen brightness, it may cause certain obstacles to the user's own viewing of the terminal. Therefore, for pages with a lower authority level, try to ensure that the user can view the content of the page more easily as much as possible. user experience.

In the above technical solution, preferably, the step 204 includes: determining the level of the preset permission according to the authentication method of the preset permission; or obtaining the application where the target page is located or the target page The priority and/or permission label corresponding to the content included in the content, and the level of the preset permission is determined according to the priority and/or category of the permission label. In this technical solution, different permissions have different authentication methods, and the differences in authentication methods often correspond to different security degrees. Then, for authentication methods with higher security degrees, the corresponding pages or pages in the pages Obviously, the content also needs higher security, so the corresponding brightness can be used for display, so as to realize the brightness grading of content display. In addition, the user may have set priority or permission labels (i.e., "important", "encrypted", "locked", "important and locked" and other labels for the application or content, specifically, when the application or content is displayed There may be a corresponding logo displayed on the logo, its function is similar to "priority"), and based on this, more accurate brightness grading of content display can be achieved.

In the above technical solution, preferably, further comprising: establishing a permission level rule database, and storing the preset permission and the level in association in the permission level rule database; and in the step 204, according to the The preset authority corresponding to the target page is searched for the corresponding level from the authority level rule database. In this technical solution, by establishing a permission level rule database, the relationship between preset permissions and brightness levels is more accurately recorded, which is beneficial to more accurately controlling the display brightness based on permissions.

The technical solution of the present invention is described in detail below in conjunction with FIG. 3 and FIG. 4A and FIG. 4B, wherein FIG. 3 shows a specific flow chart of controlling terminal display brightness according to authority settings according to an embodiment of the present invention; FIG. 4A shows A schematic diagram of an application with preset permissions according to an embodiment of the present invention; FIG. 4B shows a schematic diagram of content with preset permissions according to an embodiment of the present invention.

As shown in FIG. 3 , according to the embodiment of the present invention, the specific process of controlling the display brightness of the terminal according to the authority setting includes:

Step 302, select an application. Specifically, it may include direct selection on a standby unlocking interface, a terminal main interface, or an icon interface of an application program, or invoking the application program from a certain application program.

Step 304 , judging whether the selected application program has preset permissions, if yes, go to step 306 , otherwise go to step 318 . Wherein, the preset authority refers to the authority set in advance for the application program, so as to identify the identity of the user, so as to realize the selection of the authorized user and prohibit the operation of the unauthorized user. Specifically, for example, one or more of fingerprints, PIN codes (Personal Identification Number, personal identification code), patterns, gesture graphics, etc. may be used as corresponding authentication methods for the application program.

Step 306, query the permission level rule database to determine the permission level of the application program. Specifically, the permission level of the application program can be determined in a variety of ways. For example, in one way, the level can be set according to the authentication method of the preset permission of the application program, such as fingerprint > pattern > PIN code > gesture pattern ( Refers to the size of the corresponding permission level); in another way, it can also be based on the priority of the application or the permission label (that is, labels such as "important", "encrypted", "locked", "important and locked", etc., specifically Alternatively, a corresponding logo may be displayed on the display logo of the application program or content, and its function is similar to "priority") to set the level.

Step 308, after finding the permission level, adjust the screen brightness in real time by using the screen brightness adjustment algorithm. Specifically, the screen brightness adjustment algorithm here can be preset by the merchant, or can be set by the user according to the needs, for example, according to: when the permission level is increased by one level, the screen brightness is reduced by 20%.

It should be noted that although there is the above-mentioned step 306 in FIG. 3, that is, the determination of the authority level, in fact, in order to simplify the steps and meet the general needs of users, when it is determined in step 304 that there is a preset authority, the Adjust the brightness of the screen.

In addition, for application programs with preset permissions, such as the application program 402 shown in FIG. 4A , a certain permission identifier 404 may be marked on the application icon. Of course, FIG. 4A is only an example, and specifically, different permission identifiers 404 may be set or not set according to different permissions. It should be noted that, for some applications 402 with preset permissions, the user can make them in a "hidden" state before authentication, that is, they are not displayed on the terminal screen, and after the user authentication is successful, they can be displayed on the terminal screen.

Step 310, enter the application program.

Step 312, when entering an application program, such as by clicking a corresponding application icon, a corresponding display interface exists, and the display interface contains one or more display items as display content. Therefore, before displaying the display interface on the terminal screen, it is first necessary to determine whether the display content therein has a preset authority, and if so, proceed to step 314 , otherwise proceed to step 318 .

Among them, similar to the preset permissions of the application program, the preset permissions of the display content are permissions set in advance for the display content, so as to identify the identity of the user, so as to realize the selection of authorized users and prohibit the operation of unauthorized users . Specifically, for example, one or more of fingerprints, PIN codes (Personal Identification Number, personal identification code), patterns, gesture graphics, etc. can be used as corresponding authentication methods for the displayed content.

Step 314, query the permission level rule database to determine the permission level of the displayed content. Similar to the processing method for application programs, specifically, the authority level of the displayed content can be determined in various ways, for example, in one way, the level can be set according to the authentication method of the preset authority of the displayed content, such as fingerprint >Pattern>PIN code>Gesture graphics (refers to the size of the corresponding permission level); Labels such as "important and locked", specifically, there may be corresponding signs displayed on the displayed content, which function is similar to "priority") to set the level.

Step 316, after finding the permission level, adjust the screen brightness in real time using a preset screen brightness adjustment algorithm. Specifically, the screen brightness adjustment algorithm here can be preset by the merchant, or can be set by the user according to the needs, for example, according to: when the permission level is increased by one level, the screen brightness is reduced by 20%.

It should be noted:

First of all, although the introduction in Figure 3 is in the order of "judging the authority of the application program to adjust the screen brightness", and then "judging the authority of the displayed content to adjust the screen brightness", in fact, the It is obviously also possible for the application program to determine the authority of the displayed content separately, so as to adjust the brightness of the screen. Specifically, step 302 to step 308 or step 310 to step 316 are implemented separately.

Secondly, although there is the above-mentioned step 314 in FIG. 3, that is, the determination of the authority level, in fact, in order to simplify the steps and meet the general needs of users, when it is judged in step 312 that there is a preset authority, the screen brightness can be directly adjusted. adjust.

Again, for display content with preset permissions, such as content 406A, content 406B, and content 406C (or other display content not shown) shown in FIG. The authority identifier 404B and the authority identifier 404C (or other identifiers not shown) are marked. Of course, FIG. 4B is only an example, and different permission identifiers can be set or not set according to different permissions. It should be noted that for some display content with preset permissions (such as content 406A, content 406B and content 406C here), the user can keep it in a "hidden" state before authentication, that is, it will not be displayed on the terminal screen , and after the user is successfully authenticated, it will be displayed on the terminal screen.

The technical solution of the present invention has been described in detail above in conjunction with the accompanying drawings. Considering that in the related art, the screen display brightness of the terminal cannot be automatically adjusted, or it can only be automatically adjusted according to environmental changes, and the display content on the terminal screen cannot be compared. Good privacy protection. Therefore, the present invention proposes a terminal and a display control method, which can automatically adjust the display brightness of the terminal according to the setting of the authority, thereby limiting the screen visibility of the terminal and ensuring the privacy of the user.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
