detailed description

In order to make the purpose, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

The "plurality" mentioned herein means two or more. "And/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

The method for controlling the display screen provided by the embodiment of the present application is applied to a terminal with a flexible display screen (a telescopic screen terminal). The structure of the terminal is first described below.

Referring to FIGS. 1 to 3, the terminal 100 in the embodiment of the present application includes a housing assembly 10, a flexible display screen 30, a driving member 50 and a driving mechanism 70. The housing assembly 10 is a hollow structure; components such as the driving member 50, the driving mechanism 70, and the camera 60 can all be arranged in the housing assembly 10. It is understandable that the terminal 100 in the embodiment of the present application includes, but is not limited to, mobile terminals such as mobile phones and tablets, or other portable electronic devices. In this document, the terminal 100 is a mobile phone as an example for description.

In the implementation of the present application, the housing assembly 10 includes a first housing 12 and a second housing 14, and the first housing 12 and the second housing 14 can move relatively. In a possible implementation, the first housing 12 and the second housing 14 are slidably connected, that is, the second housing 14 can slide relative to the first housing 12.

Optionally, referring to FIGS. 4 and 5, the first housing 12 and the second housing 14 jointly form an accommodating space 16. The accommodating space 16 can be used to place components such as the driving member 50, the camera 60, and the driving mechanism 70. The housing assembly 10 may further include a back cover 18, and the back cover 18 and the first housing 12 and the second housing 14 together form an accommodating space 16.

Optionally, the driving member 50 is disposed in the second casing 14, one end of the flexible display screen 30 is disposed in the first casing 12, the flexible display screen 30 bypasses the driving member 50, and the other end of the flexible display screen is disposed in the accommodation In the space 16, part of the flexible display screen 30 is hidden in the accommodating space 16, and part of the flexible display screen 30 hidden in the accommodating space 16 may not be lit. The first housing 12 and the second housing 14 are relatively far away, and the flexible display screen 30 can be driven by the driving member 50 to expand, so that more flexible display screens 30 are exposed outside the accommodating space 16. The flexible display screen 30 exposed outside the accommodating space 16 is lighted up, so that the display area presented by the terminal 100 becomes larger.

Optionally, the driving member 50 is a rotating shaft structure with teeth 52 on the outside, and the flexible display screen 30 is linked with the driving member 50 through meshing or the like. When the first housing 12 and the second housing 14 are relatively far away, the driving member 50 drives a part of the flexible display screen 30 engaged on the driving member 50 to move and unfold.

It can be understood that the driving member 50 can also be a round shaft without teeth 52. When the first housing 12 and the second housing 14 are relatively far away, the driving member 50 will wind the part of the flexible display screen 30 on the driving member 50. Expand so that more flexible display screens are exposed outside the accommodating space 16 and are in a flat state. Optionally, the driving member 50 is rotatably disposed on the second housing 14, and when the flexible display screen 30 is gradually expanded, the driving member 50 can rotate with the movement of the flexible display screen 30. In other embodiments, the driving member 50 may also be fixed on the second housing 14, and the driving member 50 has a smooth surface. When the flexible display screen 30 is expanded, the driving member 50 can slidably contact with the flexible display screen 30 through its smooth surface.

When the first housing 12 and the second housing 14 are relatively close, the flexible display screen can be retracted by the driving member 50. Alternatively, the terminal 100 further includes a resetting member (not shown). One end of the flexible display screen housed in the accommodating space 16 is linked with the resetting member. When the first housing 12 and the second housing 14 are relatively close, the resetting member drives the flexible The display screen 30 is reset, so that part of the flexible display screen is retracted into the accommodating space 16.

In the embodiment of the present application, the driving mechanism 70 may be disposed in the accommodating space 16, the driving mechanism 70 may be linked with the second housing 14, and the driving mechanism 70 is used to drive the second housing 14 relative to the first housing 12. Performing a separation movement, thereby driving the flexible display screen assembly 30 to stretch. It can be understood that the driving mechanism 70 may also be omitted, and the user may directly move the first housing and the second housing relative to one another manually.

It should be noted that the foregoing embodiment only takes the flexible display screen being stretchable in the width direction as an example for description. In other possible terminal forms, the flexible display screen has a fixed width and is stretchable in the height direction. For example, when the flexible display screen is in the extended state, the size of the terminal is similar to that of the traditional terminal, while when the flexible display screen is in the retracted state, the height of the terminal is half of that of the traditional terminal. This embodiment does not limit this.

In the related art, when manually controlling the expansion and contraction of the flexible display screen, the user is required to hold the terminal with both hands, and control the contraction or stretching by moving the hands toward and away from each other. In some scenarios, when the user is inconvenient to hold the terminal with both hands (for example, in a crowded subway, it is necessary to hold the handrail with one hand), the flexible display screen will not be able to stretch. When using the button touch method to control the expansion and contraction of the flexible display screen, it is necessary to set virtual buttons in the user interface in advance, or set physical buttons in the terminal housing. However, when using the virtual button triggering method, the user first needs to trigger the display of the virtual buttons through a series of operations, and the process is complicated. When using the physical button triggering method, additional openings need to be provided in the terminal housing and the terminal needs to be opened. The layout of other internal components is adjusted, and the implementation cost is higher.

Using the method provided in the embodiments of the present application, the terminal should be able to determine the target display screen state in various application scenarios based on the historical display screen state of the flexible display screen, so that when the target display screen state does not match the current display screen state , The flexible display is automatically controlled to expand to the target display state, without the need to set additional virtual or physical buttons, and it can be realized even if the user holds the terminal with one hand, which simplifies the expansion and contraction process of the flexible display and improves the performance of the flexible display. The degree of telescopic intelligence. An exemplary embodiment is used for description below.

Please refer to FIG. 6, which shows a flowchart of a method for controlling a display screen provided by an exemplary embodiment of the present application. In this embodiment, the method is executed by the terminal shown in FIGS. 1 to 5 as an example for description, and the process includes the following steps:

Step 601: Acquire the current display screen state of the flexible display screen in the current application scenario, where the current display screen state includes at least one of an extended state and a retracted state.

Regarding the manner of obtaining the display screen state of the flexible display screen, in a possible implementation manner, the terminal obtains the stretching distance of the flexible display screen through a displacement sensor, so as to determine the display screen state of the flexible display screen according to the stretching distance.

Optionally, if the stretched distance of the flexible display screen is less than the first distance threshold, the terminal determines that the flexible display screen is in a retracted state, and if the stretched distance of the flexible display screen is greater than or equal to the first distance threshold, the terminal determines that the flexible display screen is stretched State, wherein the first distance threshold is less than or equal to the maximum stretch distance of the flexible display screen.

For example, if the minimum size of the exposed display area of the flexible display screen is 7×7 cm, and the maximum size is 7×14 cm, the maximum stretching distance is 7 cm. If the stretching distance of the flexible display screen is less than 7cm (that is, the exposed display area is less than 7×14cm), it is in a retracted state. If the stretching distance of the flexible display screen is equal to 7cm (that is, the exposed display area is equal to 7×14cm), it is in a Stretched state.

Of course, in addition to obtaining the display status of the flexible display screen in the above manner, the terminal can also obtain the display screen status in other ways (for example, obtaining the display screen status through a mechanical structure connected to the flexible display screen), which is not limited in this embodiment. .

Step 602: Determine the target display screen state corresponding to the current application scenario, and the target display screen state is determined according to the historical display screen state of the flexible display screen in the current application scenario.

Among them, the target display screen state is the display screen state that conforms to the user's screen scaling habits in the current application scenario.

In a possible implementation manner, the target display state is determined according to the historical display state of the flexible display screen of the current terminal in the current application scenario, that is, the target display state is determined according to the historical screen of the local user in the current application scenario The scaling habit is determined; or, the target display screen state is determined based on the historical display screen state of the flexible display screen of the associated terminal in the current application scenario, where the terminal usage habits of the user corresponding to the associated terminal are similar to the terminal usage habits of the local user.

In some embodiments, the terminal collects data on the display screen status of the flexible display screen in different application scenarios during use, and determines the target display screen status corresponding to the different application scenarios through the analysis program, and then displays the application scenarios and the target The screen status is stored associatively. When subsequently entering a certain application scenario, the state of the target display screen is directly read from the association relationship.

Since the user's preferred display status is related to many factors, such as the application currently running in the foreground (when using a video playback application, the user prefers to stretch the flexible display to the maximum size to achieve the best display effect ; When using the news reading application, the user prefers to shrink the flexible display to the smallest size to achieve one-handed touch), related to the current power information (when the power is sufficient, the user prefers to stretch the flexible display to The largest size to achieve the best display effect; and when the battery is insufficient, the user prefers to stretch the flexible display to the smallest size to reduce display power consumption and save power), related to the current location (such as in a private place) , The user prefers to stretch the flexible display to the maximum size to achieve the best display effect; while in public places, the user prefers to stretch the flexible display to the minimum size to avoid personal privacy leakage), related to the terminal's current user (For example, men have larger palms and prefer to stretch the flexible display, while women's palms prefer to shrink the flexible display). Therefore, in order to improve the accuracy of subsequent automatic display expansion and contraction control, the terminal obtains the multi-dimensionality corresponding to the current application scenario Information (that is, the application scenario is fine-grained), so as to determine the state of the target display screen according to the multi-dimensional information.

Optionally, the scene information corresponding to the current application scene includes at least one of the following: foreground application information, power information, location information, and use object information.

Among them, the foreground application information includes at least one of the foreground application identifier and the foreground application type; the power information includes at least one of the remaining power and the charging state; the location information includes the geographic location coordinates and the location type (home , Company, public transportation, etc.); the use object information includes at least one of the use object name, the use object gender, and the use object biological parameters (such as fingerprints).

Step 603: In response to the current state of the display screen does not match the state of the target display screen, control the expansion and contraction of the flexible display screen, wherein the display screen state of the flexible display screen after expansion and contraction is the target display screen state.

Further, the terminal detects whether the current display screen state matches the target display screen state, and if it does not match, the flexible display screen is controlled to expand and contract, so that the display screen state of the flexible display screen after expansion and contraction becomes the target display screen state.

In an exemplary example, as shown in FIG. 7, the terminal 701 determines the stretched state of the target display state of the flexible display screen according to the video playback application 702 currently running in the foreground. Since the current display screen state is the contracted state, The terminal controls the flexible display screen to stretch to a stretched state, and displays the video picture on the full screen in the stretched flexible display screen.

In a possible implementation manner, the terminal generates a telescopic instruction and sends the telescopic instruction to the screen mechanical component, and the screen mechanical component controls the expansion and contraction of the flexible display screen according to the telescopic instruction. Wherein, the stretch command may be a pulse width modulation (Pulse Width Modulation, PWM) signal, and the screen mechanical component may be the driving mechanism 70 shown in FIG. 4.

In some embodiments, in response to the current display screen state matching the target display screen state, the terminal controls the flexible display screen to maintain the current display screen state.

It should be noted that after the terminal automatically controls the expansion and contraction of the flexible display, the display buffer needs to be re-adjusted, and the interface elements in the user interface must be re-layouted to adapt to the screen size of the exposed display area of the flexible display (and Screen resolution), this embodiment will not be repeated here.

In summary, in the embodiments of the present application, for a terminal equipped with a flexible display screen with a variable exposed display area, the current display state of the flexible display screen in the current application scenario is obtained, and the flexible display screen To determine the target display status corresponding to the current application scene, so that when the current display status does not match the target display status, the flexible display is automatically controlled to expand and contract, so that the flexible display is in the target display state. According to the user’s habit of extending and retracting the display in different application scenarios, the flexible display is automatically extended to a display state that conforms to the user’s usage habits, without the user needing to manually stretch the flexible display, and without the user triggering the flexible display through a button. Telescopic, simplifies the telescopic process of the flexible display, and improves the telescopic intelligence of the flexible display.

Please refer to FIG. 8, which shows a flowchart of a method for controlling a display screen provided by another exemplary embodiment of the present application. In this embodiment, the method is executed by the terminal shown in FIGS. 1 to 5 as an example for description, and the process includes the following steps:

Step 801: Acquire the current display screen state of the flexible display screen in the current application scenario, where the current display screen state includes at least one of an extended state and a retracted state.

For the implementation of this step, reference may be made to the above step 601, which will not be repeated in this embodiment.

Step 802: Obtain the first time period during which the flexible display screen is in the extended state and the second time period during which the flexible display screen is in the retracted state in the current application scenario.

In a certain application scenario, the longer the holding time of the flexible display screen in a certain display state is, the more the display state conforms to the screen expansion habit in the application scenario. Therefore, in a possible implementation manner, the terminal pair In various application scenarios, the length of time the flexible display screen is in various display states is counted, so as to determine the first time length of the flexible display screen in the extended state in each application scenario (accumulate the length of time in the extended state), And the second length of time the flexible display screen is in the retracted state (obtained by accumulating the length of time in the retracted state).

In some embodiments, the terminal stores the statistical data locally in the terminal, and reads it locally when it needs to be used; in another possible implementation manner, the terminal reports the statistical data to the server, and when it needs to be used, that is, It is read from the server, which is not limited in this embodiment.

In an exemplary example, the corresponding relationship between the application scenario (explained in two dimensions including foreground application information and power information), the first duration and the second duration stored in the terminal is shown in Table 1.

Table I

前台应用信息Front desk application information	电量信息Battery information	第一时长First time	第二时长Second duration
视频播放应用程序Video playback application	大于50％More than 50%	140分钟140 minutes	20分钟20 minutes
视频播放应用程序Video playback application	小于50％Less than 50%	15分钟15 minutes	75分钟75 minutes
即时通信应用程序Instant messaging application	大于50％More than 50%	10分钟10 minutes	90分钟90 minutes
即时通信应用程序Instant messaging application	小于50％Less than 50%	12分钟12 minutes	80分钟80 minutes

After obtaining the first duration and the second duration, the terminal determines the target display screen state corresponding to the current application scenario according to the first duration and the second duration (steps 803 to 805).

Step 803: Determine the proportion of the first duration in the stretched state and the proportion of the second duration in the crimped state according to the first duration and the second duration.

In a possible implementation manner, the terminal determines the total duration of the current application scenario according to the first duration and the second duration, and then determines the proportion of the first duration in the stretched state according to the first duration and the total duration, and according to the first duration and the total duration, The second duration and the total duration determine the proportion of the second duration in the curled state.

Combining the example in Table 1, if the video playback application is currently running in the foreground and the remaining battery power is greater than 50%, the terminal determines that the first duration is 140÷(140+20)=87.5%, and the second duration is 20÷(140+20)=12.5%.

In step 804, in response to the first duration ratio being greater than the first threshold, it is determined that the state of the target display screen is the extended state.

In a possible implementation manner, the terminal is preset with a first threshold, and when the proportion of the first duration is greater than the first threshold, the terminal determines that the state of the target display screen is the extended state. For example, the first threshold is 80, 85%, or 90%.

In combination with the example in the foregoing steps, since the first duration accounted for 87.5% is greater than the first threshold 80%, the terminal determines the stretched state as the target display screen state.

In step 805, in response to the second duration ratio being greater than the second threshold, it is determined that the state of the target display screen is the contracted state.

In a possible implementation manner, the terminal is preset with a second threshold, and when the proportion of the second duration is greater than the second threshold, the terminal determines that the state of the target display screen is the scrolled state. For example, the second threshold is 75, 80%, or 85%, and so on.

Combining the example in Table 1, if the instant messaging application is currently running in the foreground and the remaining battery power is greater than 50%, the terminal determines that the second duration is 90%, because the second duration 90% is greater than the second threshold 85% , Therefore, the terminal determines the scrolling state as the target display state.

Optionally, the terminal may also pre-determine and store the corresponding relationship between different application scenarios and the status of the display screen. During subsequent use, it will directly obtain the target display status from the corresponding relationship based on the current application scenario. The example does not limit this.

It should be noted that, in addition to determining the target display state based on the holding time in the display state, in other possible implementation manners, the terminal may also determine the application based on the frequency of changes in the display state of the flexible display screen in the application scenario. The state of the target display screen corresponding to the scene is not limited in this embodiment.

In step 806, it is determined that in the state of the target display screen, the flexible display screen presents a third duration of different screen sizes, and the screen size is the size of the exposed display area of the flexible display screen.

In some embodiments, when the terminal supports stretching the flexible display to the maximum screen size and shrinking the flexible display to the minimum screen size, correspondingly, if the current display status does not match the target display status, the terminal will follow In the target display state, the flexible display screen is stretched to the maximum screen size (the target display screen state is the stretched state), or the flexible display screen is contracted to the minimum screen size (the target display screen state is the retracted state).

In another possible implementation manner, since the user is using the terminal, the flexible display screen can be stretched appropriately according to personal usage habits, that is, the screen size of the exposed display area of the flexible display screen can be located between the minimum screen size and the maximum screen size. Between screen sizes. Therefore, in order to make the screen size of the flexible display screen more in line with the user’s personal habits after auto-scaling, optionally, after the terminal determines the state of the target display screen, the target display screen state is further determined, and the flexible display screen presents the third duration of different screen sizes. . Wherein, the screen size may be a range of a screen size, or may be a specific screen size, which is not limited in this embodiment.

In an illustrative example, in the retracted state, the screen size of the flexible display is in the range of 7 to 10.5 cm, and in the stretched state, the screen size of the flexible display is in the range of 10.5 to 14 cm. When the application scenario corresponds to the target display When the state is in the extended state, the terminal determines the third duration of each screen size in the interval of 10.5 cm to 14 cm for the flexible display screen. For example, the terminal determines that the third duration under the screen size of 11cm is 10 minutes, the third duration under the screen size of 12cm is 90 minutes, and the third duration under the screen size of 13cm is 20 minutes. The third time under the 14cm screen size is 20 minutes.

Step 807: Determine the screen size corresponding to the longest third duration as the target screen size.

Further, the terminal determines the longest third duration, and determines its corresponding screen size as the target screen size. Combining the examples in the above steps, the terminal determines 12cm as the target screen size.

Optionally, the terminal may also pre-determine the corresponding relationship between different application scenarios and the target screen size, and store it. During subsequent use, it directly obtains the target screen size from the corresponding relationship based on the current application scenario. Not limited.

Step 808, in response to the current state of the display screen does not match the state of the target display screen, control the expansion and contraction of the flexible display screen according to the target screen size, wherein the size of the exposed display area of the flexible display screen after expansion and contraction is the target screen size.

In a possible implementation, if the current display status does not match the target display status, the terminal generates a telescoping command according to the target screen size, so as to send the telescoping command to the screen mechanical component, so that the screen mechanical component controls the flexible display to expand and contract. To the target screen size.

Step 809: Determine the current screen size of the flexible display screen in response to the current display screen state matching the target display screen state.

If the current display screen state matches the target display screen state, the terminal maintains the current display screen state of the flexible display screen.

In order to avoid that in the current display state, the screen size of the exposed display area of the flexible display screen may be quite different from the target screen size, which may affect the user's use, in a possible implementation manner, the terminal determines the current display area of the flexible display screen. Screen size, and then determine whether the current screen size needs to be fine-tuned according to the current screen size and the target screen size.

Step 810, in response to the size difference between the current screen size and the target screen size being less than the fourth threshold, control the flexible display screen to maintain the current screen size.

In a possible implementation, if the size difference between the current screen size and the target screen size is small, adjusting the current screen size will not significantly improve the user's use, but will interfere with the user's use due to the automatic adjustment. If the size difference between the current screen size and the target screen size is less than the fourth threshold, the flexible display screen is controlled to maintain the current screen size. For example, the fourth threshold is 0.5 cm.

In an illustrative example, if the current screen size is 12.3×7 cm and the target screen size is 12×7 cm, since the difference between the two sizes is 0.3 cm and less than 0.5 cm, the terminal maintains the current screen size.

Step 811, in response to the size difference between the current screen size and the target screen size being greater than the fourth threshold, control the flexible display screen to expand and contract according to the size difference, where the size of the exposed display area of the flexible display screen after expansion and contraction is the target screen size.

Similarly, if the size difference between the current screen size and the target screen size is small, adjusting the current screen size will significantly improve user usage. Therefore, the terminal controls the flexible display to expand and contract according to the size difference, so that the screen size of the flexible display reaches The target screen size.

In an illustrative example, if the current screen size is 13×7cm and the target screen size is 12×7cm, since the difference between the two sizes is 1cm and greater than 0.5cm, the terminal controls the flexible display to shrink by 1cm, so that The screen size reaches 12×7cm.

In the foregoing embodiments, the terminal automatically controls the expansion and contraction of the flexible display screen, so the posture of the user holding the terminal will affect the automatic expansion and contraction. In order to ensure the normal execution of automatic expansion and contraction, in a possible implementation manner, when controlling the expansion and contraction of the flexible display screen, the terminal obtains the terminal holding state, and if the terminal supports automatic expansion and contraction in the holding state, the flexible display screen is controlled to expand and contract; if If the terminal does not support automatic expansion and contraction in the holding posture, the holding posture adjustment reminder will be issued.

Regarding the manner of acquiring the holding posture of the terminal, in some embodiments, a sensor is provided at the edges of the first housing and the second housing (that is, the middle frame of the terminal). The sensor may be a touch sensor, a pressure At least one of a sensor and a thermal sensor. The terminal determines the holding posture of the terminal through the sensor data collected by the sensor.

For example, when the edge of the first housing and the edge of the second housing collect sensor data at the same time, the terminal determines that the terminal's holding posture does not support automatic expansion; when only the edge of the first housing or the edge of the second housing collects the sensor data, the terminal Make sure that the terminal holding posture supports automatic telescoping.

Optionally, the manner of reminding the holding posture adjustment may include at least one of vibration reminding, text reminding, animation reminding, and voice reminding, which is not limited in this embodiment.

In this embodiment, the terminal calculates the length of time that the flexible display screen is in the stretched state and the retracted state in the application scenario, thereby determining the target display screen state corresponding to the application scenario according to the proportion of the time duration, that is, keeping the maximum duration in the application scenario. The long display screen state is determined as the target display screen state, so that the determined target display screen state with probability conforms to the user's usage habits, and the accuracy of the automatic control of the display screen is improved.

In addition, in this embodiment, the terminal further determines the optimal screen size of the target display screen according to the holding time corresponding to different screen sizes in the target display screen state, and then controls the flexible display screen to expand and contract based on the optimal screen size. The screen size of the flexible display screen after expansion and contraction conforms to the user's personal usage habits, which further improves the user experience after the automatic expansion and contraction of the display screen.

At the same time, in this embodiment, before controlling the automatic expansion and contraction of the flexible display screen, the terminal obtains the holding state of the terminal and controls the expansion and contraction of the flexible display screen when the holding state supports automatic expansion, so as to avoid the influence of the user's holding gesture on the automatic expansion and contraction of the screen. Improve the security of automatic scaling.

For certain application scenarios that appear for the first time, or low-frequency application scenarios, since the statistical data of the display screen status in this application scenario is limited, the target display screen status determined based on the statistical data may have deviations. In order to improve the accuracy of the determined target display screen state, the terminal may obtain the target display screen state of other terminals in the application scenario from the server. On the basis of FIG. 8, as shown in FIG. 9, steps 803 to 805 can be replaced with step 8031, and after

step

802, 8032 and 8033 can also be included.

Step 8031: In response to the total usage duration in the current application scenario being greater than the third threshold, determine the target display screen state corresponding to the current application scenario according to the first duration and the second duration.

Optionally, the total usage duration is the sum of the first duration and the second duration.

If the total usage time is greater than the third threshold, the terminal determines that the statistical data in the current application scenario is sufficient, so as to determine the target display screen state according to the first time length and the second time length. For this process, please refer to the

above steps

804 and 805. In this embodiment, This will not be repeated here.

In an illustrative example, if the total use time of the current application scene is greater than 100 minutes, the terminal determines the target display screen state corresponding to the current application scene according to the first time length and the second time length.

Step 8032: In response to the total usage time in the current application scenario being less than the third threshold, send the target user portrait to the server. The target user portrait includes the display status corresponding to other application scenarios, and the display status corresponding to other application scenarios is based on other applications. The historical display status of the flexible display in the scene is determined.

In a possible implementation manner, the terminal determines the status of the display screen corresponding to different application scenarios (the total usage time of the application scenario is greater than the third threshold) according to the statistical data in different application scenarios, and determines the status of the display screen according to the difference between the application scenario and the display status. Correspondence between the two, construct the target user portrait. In an illustrative example, the target user portrait (application scenario including foreground application information, power information, and location information) contains data as shown in Table 2.

Table II

Optionally, the terminal uploads the constructed target user portrait to the server, and the server analyzes the user portraits uploaded by a large number of terminals to determine the associated terminal with similar usage habits as the current terminal.

When the total usage time in the current application scenario is less than the third threshold, the terminal sends a display screen status acquisition request to the server, which includes the scene information corresponding to the current application scenario, and requests the server to feed back the target display status corresponding to the current application scenario .

In some embodiments, in addition to the corresponding relationship between the application scenario and the status of the display screen, the user portrait may also include user information, such as user age, user gender, user region, or terminal information, such as terminal model, This implementation does not limit information such as the applications installed on the terminal and the frequency of use of the applications.

Step 8033: Receive the target display status fed back by the server. The target display status is determined by the server according to the display status corresponding to the current application scene in the reference user portrait, and the reference user portrait and the display status corresponding to other application scenarios in the target user portrait The matching degree of is greater than the matching degree threshold.

In a possible implementation manner, after the server obtains the target user portrait, it performs data conversion processing on the data therein to obtain the target portrait matrix corresponding to the target user portrait conversion, and calculates the difference between the target portrait matrix and the mass portrait matrix Matching degree, so that the portrait matrix with matching degree higher than the matching degree threshold is determined as the reference portrait matrix, and then the target corresponding to the current application scene is determined according to the reference user portrait corresponding to the reference portrait matrix (including the display status corresponding to the current application scene) Display status.

In addition, the server may also determine the similarity between the user portraits according to other information, such as the above-mentioned user information and terminal information, which is not limited in this embodiment.

The server feeds back the determined target display status to the terminal so that the terminal can also follow the target display status provided by the server (based on the screen usage habits of similar users in the current application scenario when the corresponding statistical data of the current application scenario is insufficient) (OK) to automatically expand the screen.

In this embodiment, the terminal sends a user portrait corresponding to the current terminal to the server, and the server determines a reference user portrait similar to the current user portrait from a large number of user portraits, and then according to the display screen corresponding to the current application scenario in the reference user portrait Status, determine the status of the target display screen, and feed it back to the terminal for automatic scaling control, which improves the accuracy of the screen automatic scaling control in the first application scenario or in the low-frequency application scenario.
