Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before explaining the embodiments of the present invention in detail, the application scenarios related to the embodiments of the present invention will be described.

Currently, terminals have become an indispensable part of people's lives. In use, a user may install a large number of applications in the terminal. Some applications relate to personal privacy information of a user, for example, friend information of the user and personal identity information of the user may be stored in a social application. Some financial applications or banking applications store the bank account information of the user. For another example, the shopping applications and some payment applications may also store the identity information and payment account information of the user, and even may be bound with a bank card account of the user. In this case, once the terminal is lost or used by other malicious users, the personal privacy information of the user stored in these applications will present a great safety hazard. Therefore, in order to secure personal privacy information of a user, the terminal may encrypt the application.

In addition, the user may also install applications such as videos, games and the like in the terminal, and a minor child in the user's home may use the applications to watch videos or play games without the user's knowledge, in which case the user may also encrypt the applications in order to prevent the minor child from being indulged in the videos or games.

After an application is encrypted in the above scenario, the application needs to be decrypted when it is used. Based on this, the application provides a method for decrypting the encrypted application, so that the operation flow of the decrypted application is more flexible, concise and smooth.

In the related art, when the terminal detects a click operation of a user on an encrypted application, a verification interface may be displayed to prompt the user to input verification information. Generally, the authentication information may be a password or fingerprint information. When the verification information is a password, a password input box is displayed on the verification interface, and at the moment, the user can input the password so that the terminal can verify the identity of the user according to the input password. When the verification information is fingerprint information, a fingerprint collection box is usually displayed on the verification interface, and a user needs to perform a touch operation in the fingerprint collection box. Or, if the terminal is provided with an entity physical key for fingerprint identification, prompt information is displayed in the verification interface, and the user is required to perform touch operation on the entity physical key, so that the terminal collects fingerprint information to verify the identity of the user.

As can be seen from the above description, on the one hand, no matter what kind of authentication information is used for authentication, the terminal displays the authentication interface, so that the processing process is complex for the terminal, and for the user, after clicking the application, the user has a clear and blocked feeling in sense, and cannot smoothly and consistently enter the application, but needs to stop to input additional authentication information to enter the application. On the other hand, when the user inputs the fingerprint information on the verification interface, the user needs to perform touch operation at a specified position to enable the terminal to acquire the fingerprint information of the user, and the operation is not flexible. Based on this, the embodiment of the present invention provides an application decryption method, which can solve the problems of complex operation, unsmooth operation, inflexibility, and the like in decryption application in the related art. Next, an application decryption method provided by an embodiment of the present invention will be explained in detail with reference to the drawings.

Fig. 1 is a flowchart illustrating an application decryption method according to an exemplary embodiment, and referring to fig. 1, the method may be applied to a terminal such as a smart phone, a tablet computer, and the like, and a fingerprint sensor is disposed below a display screen of the terminal, and the method specifically includes the following steps.

Step 101: and receiving a touch operation at an icon of a target application through the display screen, wherein the target application is an encrypted application.

Step 102: and starting the fingerprint sensor at the icon of the target application, and acquiring fingerprint information of the touch operation through the started fingerprint sensor.

The method comprises the steps that a plurality of fingerprint sensors are arranged below a display screen of the terminal, after the area touched by touch operation is determined, the terminal can start the fingerprint sensors in the area, and other fingerprint sensors can not be started, so that the power consumption of the terminal is reduced.

Step 103: and when the fingerprint information of the touch operation is matched with the encrypted fingerprint information of the target application, starting the target application.

In the embodiment of the invention, at least one fingerprint sensor is arranged below a display screen of the terminal, the terminal can receive touch operation at an icon of a target application through the display screen, then the fingerprint sensor at the icon of the target is started, fingerprint information of the touch operation is collected through the started fingerprint sensor, and if the collected fingerprint information of the touch operation is matched with encrypted fingerprint information of the target application, the terminal directly starts the application. Therefore, when the user opens the application, no matter where the application is located on the display screen at present, the terminal can directly collect fingerprint information of the user when the user opens the application to verify the identity of the user, a verification interface does not need to be displayed any more, the user is required to input verification information at a specific position, the operation flow is simplified, and the operation of decrypting the application by the user is more flexible, concise and smooth.

Optionally, the fingerprint sensor at the icon of the target application is launched, comprising:

acquiring receiving time of receiving touch operation;

and when the receiving time is within the preset time range, starting the fingerprint sensor at the icon of the target application.

Optionally, before collecting fingerprint information of a touch operation through the activated fingerprint sensor, the method further includes:

when an application encryption setting instruction is received, receiving at least one touch operation at an icon of at least one application through a display screen;

starting a fingerprint sensor at the icon of at least one application, and acquiring fingerprint information of at least one touch operation through the started fingerprint sensor;

determining the collected fingerprint information as encrypted fingerprint information of at least one application;

and acquiring an application identifier of at least one application, and correspondingly storing the application identifier of the at least one application and the encrypted fingerprint information of the at least one application.

Optionally, after fingerprint information of a touch operation is collected by the activated fingerprint sensor, the method further includes:

and when the times of collecting the fingerprint information which is not matched with the encrypted fingerprint information of the target application is more than the preset times, displaying prompt information, wherein the prompt information is used for prompting a user that the target application is encrypted.

All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.

Fig. 2A is a flowchart illustrating an application decryption method according to an exemplary embodiment, which may be used in a terminal such as a smart phone, a tablet computer, etc., and a fingerprint sensor is disposed below a display screen of the terminal, as shown in fig. 2A, the method includes the following steps:

step 201: when an application encryption setting instruction is received, at least one touch operation is received at an icon of at least one application through a display screen.

An application encryption setting option may be included in a setting menu of the terminal. When the user wants to encrypt the application installed in the terminal, the user can click the application encryption setting option. When the terminal receives the application encryption setting instruction, the terminal can return to a desktop of the terminal to display all the applications installed in the current terminal. Then, when the terminal receives at least one touch operation at the icon of the currently displayed at least one application through the display screen, the terminal may then determine an application acted on by the received touch operation as an application to be encrypted.

Fig. 2B is a schematic diagram of human-computer interaction during encryption setting according to an embodiment of the present invention. As shown in the left diagram of fig. 2B, after the user clicks the application encryption setting option, the terminal may display application icons of all applications currently installed in the terminal. Thereafter, as shown in the right diagram of fig. 2B, the user may select two applications, application a and application B, for encryption, so that the terminal will receive two touch operations of the user at the icon of application a and the icon of application B.

Step 202: and starting a fingerprint sensor at the icon of at least one application, and acquiring fingerprint information of at least one touch operation through the started fingerprint sensor.

In the embodiment of the invention, at least one fingerprint sensor is arranged below the display screen of the terminal. After the terminal receives at least one touch operation at the icon of at least one application through the display screen, the fingerprint sensor at the icon of the at least one application can be started, and fingerprint information of the at least one touch operation is collected through the started fingerprint sensor.

It should be noted that, if the user performs the touch operation on the icons of the plurality of applications in sequence at one time, the terminal may start the fingerprint sensor at the icon corresponding to the touch operation each time the terminal receives one touch operation, and acquire the fingerprint information of the touch operation through the fingerprint sensor. Or, the terminal may start all the fingerprint sensors at all the displayed application icons when receiving a first touch operation, and then acquire fingerprint information of the touch operation through the fingerprint sensor at the icon corresponding to the touch operation when receiving every touch operation. Or, the terminal may start only the fingerprint sensor at the icon acted by the first touch operation when receiving the first touch operation, and acquire the fingerprint information of the first touch operation through the started fingerprint sensor, and the subsequently received touch operation does not acquire the corresponding fingerprint information any more. In this case, the terminal will only collect fingerprint information for one touch operation. That is, when an application encryption setting instruction is triggered once, only one piece of encryption fingerprint information is collected for a plurality of applications to be encrypted.

Of course, if only one encrypted fingerprint information is collected for a plurality of applications to be encrypted when an application encryption setting instruction is triggered once, the fingerprint sensor started by the terminal may be the fingerprint sensor at the icon acted by the first touch operation or the fingerprint sensor at any icon of other icons receiving the touch operation.

Optionally, the terminal may start the corresponding sensor to collect fingerprint information according to at least one application icon acted by the touch operation in the above manners, and of course, the terminal may also directly start all fingerprint sensors arranged below the display screen, and then collect the fingerprint information of the user through the fingerprint sensor in the application icon acted by the touch operation in all the sensors.

Step 203: encrypted fingerprint information for at least one application is determined based on the captured fingerprint information.

After the terminal collects the fingerprint information of the user through the started fingerprint sensor, the terminal can set the encrypted fingerprint information of the at least one application according to the collected fingerprint information.

Specifically, based on the description in step 202, the method of setting the encrypted fingerprint information of the at least one application is different according to the method of collecting the fingerprint information.

When the user performs the selection operation on at least one application and the terminal collects only one piece of fingerprint information of the user, the terminal can determine the collected fingerprint information as the encrypted fingerprint information of the at least one application.

In an alternative mode, the user performs a touch operation at a plurality of application icons in sequence at one time, and activates a plurality of fingerprint sensors at the plurality of application icons to acquire fingerprint information of the touch operation, and the user performs a touch operation on different application icons through different fingers, in which case the terminal acquires a plurality of different fingerprint information. At this time, the terminal may determine the number of fingerprint information belonging to the same finger among the collected fingerprint information, and determine any one of the fingerprint information corresponding to the finger having the most fingerprint information as the encrypted fingerprint information of the plurality of applications. Of course, if the finger having the most fingerprint information cannot be determined from the collected fingerprint information, the terminal may determine the first collected fingerprint information as the encrypted fingerprint information of the plurality of applications. Alternatively, the terminal may display a fingerprint selection option to select which fingerprint information is determined as the encrypted fingerprint information of the plurality of applications by the user. That is, in such an implementation, the multiple applications would correspond to the same encrypted fingerprint information.

In another alternative, when the user performs a touch operation at the icons of the plurality of applications and the terminal correspondingly acquires a plurality of fingerprint information when the user performs the plurality of touch operations, for each of the plurality of fingerprint information, the terminal may determine the fingerprint information as encrypted fingerprint information of the application on which the touch operation that generated the fingerprint information acts.

For example, assuming that a user performs a touch operation on each of the application 1, the application 2, and the application 3, and the terminal acquires fingerprint information 1 when the user performs the touch operation on the application 1, fingerprint information 2 when the user performs the touch operation on the application 2, and fingerprint information 3 when the user performs the touch operation on the application 3, at this time, the terminal may determine the fingerprint information 1 as encrypted fingerprint information of the application 1, the fingerprint information 2 as encrypted fingerprint information of the application 2, and the fingerprint information 3 as encrypted fingerprint information of the application 3. Any two of the fingerprint information 1, the fingerprint information 2, and the fingerprint information 3 may be the same, or may be all different.

Step 204: and acquiring an application identifier of at least one application, and correspondingly storing the application identifier of the at least one application and the encrypted fingerprint information of the at least one application.

After the terminal determines the acquired fingerprint information of the at least one touch operation as the encrypted fingerprint information of the at least one application, the terminal may acquire an application identifier of the at least one application, and then store the acquired application identifier of the at least one application and the determined encrypted fingerprint information of the at least one application correspondingly. The application identifier may be an application icon, an application name, or other information that can uniquely identify the application.

It should be noted that, as described in step 203, when at least one application corresponds to the same encrypted fingerprint information, the terminal may store the encrypted fingerprint information and the application identifier of the at least one application correspondingly. When each application corresponds to one piece of encrypted fingerprint information, the terminal can correspondingly store the encrypted fingerprint information and the application.

Optionally, the user may only want to encrypt the at least one application for a certain period of time, in one possible scenario. For example, for some gaming applications, to prevent a minor child in the home from opening the gaming application, the user may encrypt the application for a time period set by the minor child according to the time period. For example, between 18:00 and 24:00, the user may be traveling home from work with a minor child, in which case the at least one application may be an encrypted application during the time period to prevent the minor child from launching the application, and at other times than that, the application may be an unencrypted application. Of course, the user may also set to encrypt at least one application within a certain time period in other scenarios, where the above scenario is only one possible application scenario shown in the embodiment of the present invention, and does not constitute a limitation on a usage scenario of the encryption manner.

Specifically, based on the above description, the terminal may further obtain a preset time range input or selected by the user after obtaining the at least one application identifier, where the preset time range is an encryption time period of the at least one application, that is, the at least one application is an encryption application in the preset time range, and is a non-encryption application at other times outside the preset time range.

In addition, this step may be executed after step 203, or after step 201 or simultaneously with step 203, which is not specifically limited in this embodiment of the present invention.

In the embodiment of the present invention, the terminal may encrypt the application through steps 201-204, and it should be noted that the above is only one possible encryption method shown in the embodiment of the present invention, and does not constitute a limitation on the encryption method. In practical applications, the terminal may also display the application list when detecting the application encryption setting instruction, and when detecting a selection operation of the user for at least one application in the application list, the terminal may prompt the user to input fingerprint information. At this time, the user may input fingerprint information at any position of the display screen of the terminal, and the terminal may determine the acquired fingerprint information as the encrypted fingerprint information of the at least one application. Of course, the terminal may also encrypt the application through the fingerprint information with reference to the related art, and the embodiment of the present invention is not described again.

It should be further noted that, based on the above description, in the embodiment of the present invention, encrypting the application installed in the terminal is a system-level encryption behavior, that is, the terminal itself encrypts the application, and the subsequent decryption is also performed by the terminal itself.

After the terminal encrypts the application, when the user uses the encrypted application, the terminal may decrypt the application by the method described in step 205-.

Step 205: and receiving a touch operation at an icon of a target application through the display screen, wherein the target application is an encrypted application.

When a user wants to open a certain encrypted application, the user may perform a touch operation on an icon of the target application. Wherein the target application is the encrypted application that the user currently wants to open. In this case, the terminal may detect in real time whether a touch operation for the encrypted application is received.

It should be noted that the terminal may display the encrypted application in a display manner of displaying the unencrypted application. That is, when the terminal displays the application icon, the encrypted application and the non-encrypted application may not be distinguished.

In another possible implementation manner, the user may not need to perform a touch operation on the target application, but may perform the touch operation at any position on the display screen of the terminal. In this case, the terminal only needs to receive the touch operation of the user through the display screen, that is, step 205 may also be to receive the touch operation through the display screen.

Step 206: and starting a fingerprint sensor at the icon of the target application, and acquiring fingerprint information of the touch operation through the started fingerprint sensor.

After the terminal receives a touch operation at an icon of a target application, the terminal may start a fingerprint sensor at the icon of the application and collect fingerprint information generated by the touch operation through the started fingerprint sensor.

Optionally, when the target application is an application encrypted within a preset time range, the terminal may further obtain a receiving time for receiving the touch operation. Then, the terminal may determine whether the receiving time is within a preset time range, and if the receiving time is within the preset time range, the target application is an encrypted application, that is, the terminal needs to decrypt the target application, and at this time, the terminal may start the fingerprint sensor at the icon where the touch operation is performed to collect the fingerprint information of the touch operation.

Of course, if the touch operation of the user at any position on the display screen is received through the display screen in step 205, the terminal may directly start the multiple fingerprint sensors disposed below the display screen of the terminal when receiving the touch operation, and collect the fingerprint information of the touch operation through the fingerprint sensor located at the position acted by the touch operation among the multiple fingerprint sensors.

Step 207: and when the acquired fingerprint information of the touch operation is matched with the encrypted fingerprint information of the target application, starting the target application.

Based on the relevant description in step 205, if the terminal receives a touch operation at the icon of the target application through the display screen, after the fingerprint information of the touch operation is collected by the fingerprint sensor at the icon of the target application, the terminal may compare the fingerprint information with the encrypted fingerprint information of the target application, and if the collected fingerprint information of the touch operation matches the encrypted fingerprint information of the target application, the target application may be started. If the acquired fingerprint information is not matched with the encrypted fingerprint information of the target application, the terminal does not respond to the touch operation of the user, namely, the target application cannot be started.

Further, the terminal can also count the times of fingerprint information which is acquired within a preset time length and is not matched with the encrypted fingerprint information of the target application, and when the times are greater than the preset times, prompt information is displayed to prompt a user that the target application is encrypted.

Specifically, in the embodiment of the present invention, the terminal may not distinguish between displaying the encrypted application and the non-encrypted application, so that when other users than the user of the terminal start the target application, the terminal will not start the target application and will not display other information because the input fingerprint information does not match the encrypted fingerprint information of the target application, and for the other users of the terminal, the other users may not know that the reason why the target application is not started is that the target application is the encrypted application. In this case, when the terminal receives the wrong fingerprint information continuously and repeatedly, the terminal may display a prompt message to prompt the user that the target application is encrypted, so that the user stops touch operation, thereby reducing the processing procedure of the terminal that is wasted for many times.

Optionally, in another possible implementation manner, if in step 205, as long as the terminal detects a touch operation of a user, fingerprint information of the touch operation may be collected, then, after the terminal collects the fingerprint information of the touch operation through a started fingerprint sensor, the terminal may search, from stored fingerprint information, whether there is encrypted fingerprint information matching the fingerprint information, and if the encrypted fingerprint information matching the collected fingerprint information is found, the terminal may directly decrypt at least one application corresponding to the encrypted fingerprint information. That is, the terminal may decrypt the application corresponding to the fingerprint information through the fingerprint information generated by any touch operation performed by the user, and then, when the user wants to start the corresponding application, the application may be directly started, and other applications that do not match with the fingerprint information are still in the encrypted state, and the user cannot start the applications in the encrypted state. Further, the terminal may set a timer while decrypting the corresponding at least one application by the fingerprint information generated by the arbitrary touch operation. The terminal may maintain the at least one application in a decrypted state when the timer is not counted up to a predetermined time length, and may convert the at least one application into an encrypted application again when the timer is counted up to the predetermined time length. That is, after the terminal decrypts at least one application, the user may directly start the application without verifying the identity for a predetermined time period after decryption, and if the user starts the application after the predetermined time period, the user needs to perform authentication again.

In the embodiment of the invention, a plurality of fingerprint sensors can be arranged below a display screen of the terminal, the terminal can receive touch operation at an icon of a target application through the display screen, start the fingerprint sensor at the icon of the target application, acquire fingerprint information of the touch operation through the started fingerprint sensor, and directly start the application if the acquired fingerprint information of the touch operation is matched with the encrypted fingerprint information of the target application. Therefore, when the user opens the application, no matter where the application is located on the display screen, the terminal can directly collect the fingerprint information of the user when the user opens the application to verify the identity of the user, and the user does not need to input verification information at a specific position by specially displaying a verification interface, so that the operation flow is simplified, and the operation of decrypting the application by the user is more flexible. Because the terminal does not need to display a verification interface, for a legal user, when the finger of the application clicked by the user is the same as the finger used when the application is set, the user can directly start and enter the application, the use experience is not blocked, and the whole decryption process is smoother.

In addition, in the embodiment of the invention, the terminal can also be arranged to encrypt at least one application within a preset time range, so that the encryption of the application becomes more flexible, and the situation that the immature children in the family are indulged in entertainment applications such as games and the like can be effectively prevented.

The processor 410 connects various parts within the overall terminal 400 using various interfaces and lines, performs various functions of the terminal 400 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 420, and calling data stored in the memory 420. Alternatively, the processor 410 may be implemented in hardware using at least one of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA). The processor 410 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is responsible for rendering and drawing the content to be displayed by the touch display 430; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 410, but may be implemented by a single chip.

The Memory 420 may include a Random Access Memory (RAM) or a Read-Only Memory (Read-Only Memory). Optionally, the memory 420 includes a non-transitory computer-readable medium. The memory 420 may be used to store instructions, programs, code, sets of codes, or sets of instructions. The memory 420 may include a stored program area and a stored data area, wherein the stored program area may store instructions for implementing an operating system, instructions for at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing the various method embodiments described above, and the like; the storage data area may store data (such as audio data, a phonebook) created according to the use of the terminal 400, and the like.

Taking an operating system as an Android (Android) system as an example, programs and data stored in the memory 420 are as shown in fig. 6, and a Linux kernel layer 520, a system runtime layer 540, an application framework layer 560, and an application layer 580 are stored in the memory 420. The Linux kernel layer 520 provides underlying drivers for various hardware of the terminal 400, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 540 provides main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system Runtime layer 540 is an Android Runtime library (Android Runtime), which mainly provides some core libraries and can allow developers to write Android applications using the Java language. The application framework layer 560 provides various APIs that may be used in building applications, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, session management, resource management, and location management. At least one application program runs in the application layer 580, and the application programs may be a contact program, a short message program, a clock program, a camera application, and the like of the operating system; or an application program developed by a third-party developer, such as an instant messaging program, a photo beautification program, and the like.

Taking an operating system as an IOS system as an example, programs and data stored in the memory 420 are shown in fig. 5, and the IOS system includes: a Core operating system Layer 620(Core OS Layer), a Core Services Layer 640(Core Services Layer), a Media Layer 660(Media Layer), and a touchable Layer 680(Cocoa Touch Layer). The kernel operating system layer 620 includes an operating system kernel, drivers, and underlying program frameworks that provide functionality closer to hardware for use by program frameworks located in the core services layer 640. The core services layer 640 provides system services and/or program frameworks, such as a Foundation framework, an account framework, an advertisement framework, a data storage framework, a network connection framework, a geographic location framework, a motion framework, etc., that are needed by the application. The media layer 660 provides audiovisual interfaces for applications, such as graphics-related interfaces, audio-related interfaces, video-related interfaces, and audio/video transmission technology wireless playback (AirPlay) interfaces. The touchable layer 680 provides various commonly used interface-related frameworks for application development, and the touchable layer 680 is responsible for user touch interaction operations on the terminal 400. Such as a local notification service, a remote push service, an advertising framework, a game tool framework, a messaging User Interface (UI) framework, a User Interface UIKit framework, a map framework, and so forth.

In the framework illustrated in FIG. 5, the framework associated with most applications includes, but is not limited to: a base framework in the core services layer 640 and a UIKit framework in the touchable layer 680. The base framework provides many basic object classes and data types, provides the most basic system services for all applications, and is UI independent. While the class provided by the UIKit framework is a basic library of UI classes for creating touch-based user interfaces, iOS applications can provide UIs based on the UIKit framework, so it provides an infrastructure for applications for building user interfaces, drawing, processing and user interaction events, responding to gestures, and the like.

The touch display screen 430 is used for receiving a touch operation of a user on or near the touch screen using any suitable object such as a finger, a touch pen, or the like, and displaying a user interface of each application. The touch display 430 is generally provided at a front panel of the terminal 400. The touch display screen 430 may be designed as a full-face screen, a curved screen, or a profiled screen. The touch display 430 can also be designed as a combination of a full-screen and a curved-surface screen, and a combination of a special-shaped screen and a curved-surface screen, which is not limited in this embodiment. Wherein:

full screen

A full screen may refer to a screen design where the touch display 430 occupies more than a threshold (e.g., 80% or 90% or 95%) of the screen of the front panel of the terminal 400. One way of calculating the screen occupation ratio is as follows: (area of touch display 430/area of front panel of terminal 400) × 100%; another way to calculate the screen ratio is: (area of actual display area in touch display 430/area of front panel of terminal 400) × 100%; another calculation method of the screen occupation ratio is as follows: (diagonal of touch display 430/diagonal on front panel of terminal 400) × 100%. In the illustrative example shown in fig. 6A, nearly all areas on the front panel of the terminal 400 are the touch display 430, and all areas on the front panel 70 of the terminal 400 except for the edge created by the bezel 71 are the touch display 430. The four corners of the touch display screen 430 may be right angles or rounded.

A full-screen may also be a screen design that integrates at least one front panel component within or underneath the touch display screen 430. Optionally, the at least one front panel component comprises: cameras, fingerprint sensors, proximity light sensors, distance sensors, etc. In some embodiments, other components on the front panel of the conventional terminal are integrated in all or a part of the touch display screen 430, for example, after the light sensing element in the camera is split into a plurality of light sensing pixels, each light sensing pixel is integrated in a black area in each display pixel in the touch display screen 430. The full-screen has a higher screen-to-screen ratio due to the integration of at least one front panel component inside the touch display screen 430.

Of course, in other embodiments, the front panel component of the front panel of the conventional terminal may be disposed at the side or back of the terminal 400, such as disposing the ultrasonic fingerprint sensor below the touch screen 430, disposing the bone conduction handset inside the terminal 400, and disposing the camera head in a pluggable structure at the side of the terminal.

In some optional embodiments, when the terminal 400 employs a full-screen, a single side, or two sides (e.g., two left and right sides), or four sides (e.g., four upper, lower, left and right sides) of the middle frame of the terminal 400 is provided with an edge touch sensor, and the edge touch sensor is configured to detect at least one of a touch operation, a click operation, a press operation, a slide operation, and the like of a user on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like. The user may apply operations on the edge touch sensor to control applications in the terminal 400.

Curved surface screen

A curved screen refers to a screen design where the screen area of the touch display screen 430 does not lie in one plane. Generally, curved screens present at least one such section: the section is in a curved shape, and the projection of the curved screen in any plane direction perpendicular to the section is a planar screen design, wherein the curved shape can be U-shaped. Alternatively, a curved screen refers to a screen design where at least one side is curved. Alternatively, the curved screen means that at least one side edge of the touch display screen 430 extends to cover the middle frame of the terminal 400. Since the side of the touch display screen 430 extends to cover the middle frame of the terminal 400, that is, the middle frame which does not have the display function and the touch function originally is covered as the displayable area and/or the operable area, the curved screen has a higher screen occupation ratio. Alternatively, as in the example shown in fig. 6B, the curved screen refers to a screen design in which the left and right side edges 72 are curved; or, the curved screen refers to a screen design in which the upper and lower sides are curved; or, the curved screen refers to a screen design in which the upper side, the lower side, the left side and the right side are all in a curved shape. In an alternative embodiment, the curved screen is made of a touch screen material with certain flexibility.

Special-shaped screen

The special-shaped screen is a touch display screen with an irregular shape, and the irregular shape is not a rectangle or a rounded rectangle. Optionally, the irregular screen refers to a screen design in which a protrusion, a notch, and/or a cutout is provided on the rectangular or rounded rectangular touch display screen 430. Alternatively, the protrusions, indentations, and/or cutouts may be located at the edges of the touch screen 430, at the center of the screen, or both. When the protrusion, the notch and/or the dug hole are arranged on one edge, the protrusion, the notch and/or the dug hole can be arranged in the middle or at two ends of the edge; when the projection, notch and/or cutout is provided in the center of the screen, it may be provided in one or more of an upper region, an upper left region, a left side region, a lower left region, a lower right region, a right side region, and an upper right region of the screen. When the projections, the notches and the dug holes are arranged in a plurality of areas, the projections, the notches and the dug holes can be distributed in a concentrated mode or in a dispersed mode; the distribution may be symmetrical or asymmetrical. Optionally, the number of projections, indentations and/or cutouts is also not limited.

The special-shaped screen covers the upper forehead area and/or the lower forehead area of the touch display screen as the displayable area and/or the operable area, so that the touch display screen occupies more space on the front panel of the terminal, and the special-shaped screen also has a larger screen occupation ratio. In some embodiments, the indentation and/or cutout is configured to receive at least one front panel component therein, the front panel component including at least one of a camera, a fingerprint sensor, a proximity light sensor, a distance sensor, an earpiece, an ambient light level sensor, and a physical key.

For example, the notch may be provided on one or more edges, and the notch may be a semicircular notch, a right-angled rectangular notch, a rounded rectangular notch, or an irregularly shaped notch. In the example shown in fig. 6C, the special-shaped screen may be a screen design with a semicircular notch 73 at the center of the upper edge of the touch display screen 430, and the semicircular notch 73 is used to accommodate at least one of a front panel component of a camera, a distance sensor (also called a proximity sensor), an earphone, and an ambient light sensor; as schematically shown in fig. 6D, the shaped screen may be a screen design having a semicircular notch 74 at a central position of the lower edge of the touch display screen 430, where the semicircular notch 74 is free for accommodating at least one of a physical key, a fingerprint sensor, and a microphone; in an exemplary example shown in fig. 6E, the special-shaped screen may be a screen design in which a semi-elliptical notch 75 is formed in the center of the lower edge of the touch display screen 430, and a semi-elliptical notch is also formed on the front panel of the terminal 400, and the two semi-elliptical notches form an elliptical area for accommodating a physical key or a fingerprint identification module; in the illustrative example shown in fig. 6F, the contoured screen may be a screen design having at least one aperture 76 in the upper half of the touch screen display 430, the aperture 76 being free to receive at least one of a camera, a distance sensor, an earpiece, and an ambient light level sensor.
