Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of steps of a reminding method for screen state switching according to an embodiment of the present invention, where the method is applicable to a mobile terminal, and a screen of the mobile terminal is a foldable screen, as shown in fig. 1, the method may include:
In the embodiment of the present invention, the current display frame may be a frame displayed in a current screen, and the related parameter may be a parameter that affects a degree of adaptation between the current display frame and a current screen state of the screen, for example, users may have different requirements for using different application programs, for example, some applications are used in situations where the display area is large, enabling the content of the application to be better displayed, the adaptation of the picture to the current screen state may therefore vary from application to application and, accordingly, the related parameter may be an identifier of an application program to which the current display screen belongs, and further, in an actual application scenario, a picture with an irregular size may appear, and the adaptation degree of the picture with different size to the current screen state may be different, and accordingly, the related parameter may be the picture resolution of the current display picture.
In the embodiment of the present invention, the screen state adapted to the current display screen refers to a screen state capable of optimizing the display effect of the current display screen, for example, if the display effect of the current display screen is optimal in the state that the screen is unfolded, it may be determined that the screen state adapted to the current display screen is an unfolded state, and accordingly, if the display effect of the current display screen is optimal in the state that the screen is folded, it may be determined that the screen state adapted to the current display screen is a folded state. Further, since the screen states adapted to different current display pictures may be different, in the embodiment of the present invention, the mobile terminal may determine, according to the related parameter of the current display picture, which screen state the display effect of the current display picture can be optimized in.
103, if the current screen state of the screen is not matched with the target screen state, outputting target reminding information corresponding to the target screen state; the target reminding information is used for reminding a user of switching the current screen state to the target screen state.
In the embodiment of the present invention, if the current screen state is not consistent with the target screen state, the current screen state and the target screen state may be considered to be not matched, for example, if the current screen state is a folded state and the target screen state is an unfolded state, the current screen state and the target screen state may be considered to be not matched, and accordingly, if the current screen state is an unfolded state and the target screen state is a folded state, the current screen state and the target screen state may be considered to be not matched.
Further, if the current screen state of the screen is not matched with the target screen state, it may be considered that the current display picture is not matched with the actual display area provided by the screen in the current screen state, and therefore, target reminding information corresponding to the target screen state may be output to the user, where the target reminding information is used to remind the user to switch the current screen state to the target screen state, and the target reminding information may be information of a text type, or information of a voice type, an animation type, or the like, and the embodiment of the present invention does not limit this.
In summary, in the reminding method for switching the screen state provided in the embodiment of the present invention, the mobile terminal may obtain the relevant parameters of the current display picture in the screen, then determine the screen state adapted to the current display picture based on the relevant parameters, to obtain the target screen state, where the target screen state is a folded state or an unfolded state, and finally, if the current screen state of the screen is not matched to the target screen state, output the target reminding information corresponding to the target screen state, where the target reminding information is used to remind the user to switch the current screen state to the target screen state. In the embodiment of the invention, when the current screen state is not matched with the target screen state, namely the current display picture is not matched with the current screen state, the target reminding information is output to the user, so that the user is reminded to switch the screen state to the state matched with the current display picture in time, the problem that the current screen state is not matched with the current display picture is further reduced to a certain extent, and the display effect of the mobile terminal is improved.
Example two
Fig. 2 is a flowchart of steps of a reminding method for screen state switching according to a second embodiment of the present invention, where the method is applicable to a mobile terminal, and a screen of the mobile terminal is a foldable screen, as shown in fig. 2, the method may include:
For example, the related parameter may be an identifier of an application program to which the current display screen belongs, the identifier of the application program may be an identifier that can be used to uniquely distinguish the application program, and the identifier of the application program may be a name of the application program, a number of the application program, or the like. Accordingly, the mobile terminal may obtain actual data corresponding to the current display screen from the background data, and then extract the identifier of the application program from the obtained data. Further, the related parameter may also be a picture resolution of the current display picture, and accordingly, the mobile terminal may read actual data corresponding to the current display picture from the background data, determine the number of pixels of the current display picture in the horizontal direction based on the corresponding actual data, and determine the number of pixels of the current display picture in the vertical direction based on the corresponding actual data, thereby obtaining the picture resolution of the current display picture.
In this step, if the relevant parameter is the identifier of the application program to which the current display screen belongs, step 202 can be implemented by steps 2021 to 2022 in the first implementation manner:
the implementation mode is as follows:
step 2021, taking the identifier of the application program to which the current display screen belongs as a target identifier, and searching for the screen state corresponding to the target identifier from a preset correspondence relationship between the application program identifier and the screen state.
In this step, the preset correspondence relationship between the application identifier and the screen state may include each application identifier and its corresponding screen state, where the screen state corresponding to each application identifier may be a screen state that is preset for the application program and is adapted to the main display content of the application program based on the characteristics of the display content corresponding to the main function of the application program by a developer. For example, assuming that the main function of the application a is text reading, since the main display content of the application a is often a text when the user uses the application to read the text, and the text is usually displayed in a folded state, a better display effect can be achieved, it can be determined that the screen state adapted to the application a is the folded state, accordingly, the corresponding relationship between the identifier of the application a and the folded state can be established in the corresponding relationship between the identifier of the application and the screen state, further, assuming that the main function of the application b is a game, since the user uses the application to play the game, the main display content of the application is often a dynamic picture, and the dynamic picture in the game is usually displayed in an unfolded state to achieve a better display effect, therefore, the screen state adapted to the application program b can be determined to be the expansion state, and accordingly, the correspondence between the identifier of the application program b and the expansion state can be established in the correspondence between the identifier of the application program b and the screen state.
In the embodiment of the invention, the adaptive screen states are preset for different application programs based on the characteristics of the display contents corresponding to the main functions of the different application programs to establish the corresponding relation between the application program identifier and the screen state, and the screen state corresponding to the application program to which the current display picture belongs is searched from the corresponding relation to be used as the target screen state, so that in the subsequent steps, the mobile terminal can remind a user of switching the current screen state to the screen state adaptive to the application program to which the current display picture belongs, the user experience when the user uses the application program to which the current display picture belongs can be improved, and the current display effect is improved.
Further, the application identifier and screen state correspondence may include: and the application program identification and application type corresponding relation and the application type and screen state corresponding relation. Specifically, since the applications of the same category often have the same main function, and thus, the screen states adapted to the main display contents of the respective application programs in the same category often coincide with each other, in the embodiment of the present invention, the category to which each application program belongs may be determined in advance based on the main function of each application program, and the correspondence between the application program identifier and the application category is established, and then, the screen state corresponding to each application category is determined based on the main function corresponding to each application category, and the correspondence between the application category and the screen state is established, so that the correspondence between the application program identifier and the screen state is obtained.
Accordingly, step 2021 may be achieved by the following sub-steps (1) to (2):
substep (1): and searching the application category corresponding to the application program identifier matched with the target identifier from the corresponding relation between the application program identifier and the application category to obtain the target category.
Specifically, when the correspondence between the application identifier and the application category is established in advance, the category to which each application belongs may be determined based on the main function of each application in a manner determined manually, for example, the category to which "some letter" of the application belongs may be determined as a social category, the category to which "clan X" of the application belongs may be determined as a game category, the category to which "some reading" of the application belongs may be determined as a reading category, and the like in a manner determined manually. Of course, it may also be that icons of each application program included in different application categories are collected and stored in advance, then when a category to which a certain application program belongs is judged, the similarity between the icon of the application program and the icon of each application program collected in advance may be judged by using a graph recognition technology, finally, the application category corresponding to the icon with the highest similarity is determined as the category to which the application program belongs, further, keywords capable of embodying the main function of each application category may be collected and stored in advance, for example, for a text type application program, keywords may be preset as "read", and the like, then when a category to which a certain application program belongs is judged, the matching degree between the semantic meaning represented by the name of the application program and the semantic represented by the keyword corresponding to each application category may be judged by using a semantic recognition technology, and finally, determining the application category corresponding to the highest matching degree as the category to which the application program belongs.
Further, the application identifier and application category corresponding relationship may be pre-stored in the local of the mobile terminal, or may be stored in the cloud, and accordingly, when the mobile terminal searches for the target category from the application identifier and application category corresponding relationship, the application identifier and application category corresponding relationship may be read locally, or the application identifier and application category corresponding relationship may be obtained from the cloud. Then, the mobile terminal may match each application identifier in the correspondence between the application identifier and the application category with the target identifier one by one, and finally, take the application category corresponding to the application identifier matched with the target identifier as the target category. If the similarity between the application identifier and the target identifier reaches a preset similarity threshold, the application identifier is considered to be matched with the target identifier, and the preset similarity threshold may be preset, for example, the preset similarity threshold may be 99%.
It should be noted that, in practical applications, one application program may correspond to a plurality of main functions, that is, may belong to a plurality of categories, and therefore, in the embodiment of the present invention, a weight may also be set for an application category corresponding to each main function based on a frequency with which each main function of the application program is used, and accordingly, when an identifier of the application program matches with a target identifier, an application category with a highest weight may be taken as the target category. Meanwhile, by pre-storing a plurality of corresponding application categories and taking the application category with the highest weight as the target category, when the frequency of using each main function changes, the mobile terminal can be conveniently controlled to determine the application category with the highest weight after adjustment as the target category by correspondingly adjusting the weights of the plurality of application categories corresponding to the application program, and of course, only the application category with the highest weight corresponding to the application program can be stored, which is not limited in the embodiment of the present invention.
Substep (2): and searching the screen state corresponding to the application category matched with the target category from the corresponding relation between the application category and the screen state to obtain the screen state corresponding to the target identifier.
Specifically, when the correspondence between the application category and the screen state is established in advance, the screen state may be adapted to the application category in advance based on the characteristics of the display content corresponding to the same main function of each application program in the application. For example, the corresponding screen state is set to the folded state for the text category, and the corresponding screen state is set to the expanded state for the game category. Further, the application category and screen state corresponding relationship may be pre-stored locally in the mobile terminal, or may also be stored in the cloud, and accordingly, the mobile terminal may first read the application category and screen state corresponding relationship locally, or obtain the application category and screen state corresponding relationship from the cloud. Then, the mobile terminal may match each application category in the correspondence between the application category and the screen state with the target category one by one, and further search for a screen state corresponding to the application category matched with the target category, that is, a screen state corresponding to the target identifier.
In an actual application scene, a large number of application programs often exist, if a mode of a corresponding relation between an identifier of an application program and a screen state is directly established in advance based on a screen state corresponding to each application program, when the screen state corresponding to a target identifier is searched, the target identifier needs to be matched with the identifiers of the large number of application programs one by one to determine the corresponding screen state, in the embodiment of the invention, the target class can be determined by establishing the corresponding relation between the identifier of the application program and the application class in advance and the corresponding relation between the application class and the screen state in advance, then the corresponding screen state can be determined by matching each application class in the corresponding relation between the target class and the application class and the screen state, and as the number of the application classes is far smaller than the number of the application programs, therefore, the cost for determining the matched screen state can be reduced to a certain extent, and the determination efficiency is improved.
Step 2022, determining the screen state corresponding to the target identifier as the target screen state.
For example, assuming that the screen state corresponding to the target identifier is a folded state, it may be determined that the target screen state is a folded state.
Further, in an actual application scenario, during the process of using the mobile terminal, the user may control the mobile terminal to display some unconventional-sized frames, such as a long screenshot, or video frames with different resolutions, and so on, so that the relevant parameter may also be the frame resolution of the currently displayed frame, and accordingly, step 202 may be implemented through steps 2023 to 2025 in the following implementation manner two:
the implementation mode two is as follows:
step 2023, acquiring the display resolution of the current display area of the screen and the current screen state of the screen.
Specifically, when the display resolution of the current display area of the screen is obtained, a screenshot of the screen display content may be performed, and then the number of pixels of the screenshot in the horizontal direction and the number of pixels in the vertical direction are calculated, so as to obtain the display resolution of the current display area. Further, in an actual application scenario, in a mobile terminal configured with a foldable screen, the display resolution of the display area of the screen in the folded state and the display resolution of the display area in the unfolded state are often pre-stored, and accordingly, when the current screen state is acquired, the screen state corresponding to the display resolution matching the acquired display resolution may be determined as the current screen state based on comparing the acquired display resolution with the pre-stored display resolution of the display area in a different screen state, for example, assuming that the display resolution of the screen of the mobile terminal in the folded state is 2000 × 1000, and the display resolution in the unfolded state is 4000 × 1000, when the display resolution of the current display area matches 2000 × 1000, the current screen state may be determined as the folded state, accordingly, when the display resolution of the current display area matches 4000 × 1000, the current screen state may be determined to be the expanded state.
Step 2024, if the resolution of the image is not greater than the display resolution and the current screen state is the extended state, determining that the target screen state is the folded state.
In this step, if the resolution of the currently displayed picture is not greater than the resolution of the currently displayed area of the screen and the current screen state is the expanded state, it can be considered that the currently displayed picture is not required to be displayed with a large display area, and at this time, the target screen state can be determined to be the folded state, so as to remind the user to switch the screen to the folded state in the subsequent steps, thereby reducing unnecessary consumption of electric quantity of the mobile terminal to a certain extent and reducing unnecessary waste of mobile terminal resources.
Step 2025, if the frame resolution is greater than the display resolution and the current screen state is a folded state, determining that the target screen state is an unfolded state.
In this step, if the resolution of the currently displayed picture is greater than the resolution of the currently displayed area of the screen and the current screen state is the folded state, it may be considered that the currently displayed picture is displayed in a smaller display area, and there may be a problem that the currently displayed picture is compressed and displayed.
In the embodiment of the invention, the target screen state is determined based on the picture resolution of the current display picture and the display resolution of the current display area in the current screen state, so that in the subsequent steps, the user can be reminded to switch the screen state to the unfolding state based on the target screen state under the condition that the current display area of the screen is too small, thereby improving the display effect of the current display picture, and switch the screen state to the folding state under the condition that the current display area of the screen is too large, thereby improving the display effect of the current display picture and reducing unnecessary waste of mobile terminal resources.
Specifically, the step 103 may be referred to in an implementation manner of this step, and this is not limited in this embodiment of the present invention.
Further, corresponding to the second implementation manner in step 202, after the mobile terminal outputs the target reminding information, the user may correspondingly adjust the screen state based on the target reminding information, and accordingly, the mobile terminal may further perform the following steps a to C after step 203, so as to further improve the viewing experience of the user:
and step A, if the current screen state is detected to be set to be the state matched with the target screen state, acquiring the aspect ratio of the current display picture and the aspect ratio of the current display area of the screen.
For example, if the target screen state is a folded state, it may be confirmed that the current screen state is detected to be set to a state that fits the target screen state when the current screen state is set to the folded state, and correspondingly, if the target screen state is an expanded state, it may be confirmed that the current screen state is detected to be set to a state that fits the target screen state when the current screen state is set to the expanded state. Further, the mobile terminal may calculate a ratio of the number of pixels in the horizontal direction to the number of pixels in the vertical direction of the current display screen to obtain an aspect ratio of the current display screen, and calculate a ratio of the number of pixels in the horizontal direction to the number of pixels in the vertical direction of the current display area to obtain an aspect ratio of the current display area.
And B, calculating the ratio of the aspect ratio of the current display picture to the aspect ratio of the current display area.
For example, assuming that the aspect ratio of the current display screen is 1:1 and the aspect ratio of the current display area is 2:1, a ratio of 1:1/2:1 to 0.5 may be obtained.
And C, if the ratio falls out of the preset ratio range, adjusting the aspect ratio of the current display picture so as to enable the ratio to fall into the preset ratio range.
Specifically, the preset ratio range may be preset by a developer according to an actual situation, for example, the preset ratio range may be [0.7, 1.3], and accordingly, if the ratio falls outside the preset ratio range, the ratio of the current display screen to the ratio of the current display area may be considered to be greatly different, and accordingly, the aspect ratio of the current display screen may be adjusted, for example, the aspect ratio of the current display screen may be adjusted to 1.4:1, so that the ratio falls within the preset ratio range, and thus, the difference between the ratio of the current display screen to the ratio of the current display area may be reduced, so that the current display screen looks more harmonious in the current display area, and the display effect is further improved.
And step 204, acquiring the current residual power of the mobile terminal.
In this step, the mobile terminal may determine a current value of current battery input/output, and then integrate the current value with respect to time to obtain the current remaining power.
In this step, the preset electric quantity threshold may be preset according to an actual situation, for example, the preset electric quantity threshold may be 30%, or the preset electric quantity threshold may also be 20%, further, the preset electric quantity threshold may be stored locally in the mobile terminal, or may also be stored in the preset server, and accordingly, the mobile terminal may obtain and store the preset electric quantity threshold from the preset server in a preset period, which is not limited in the embodiment of the present invention. Specifically, the mobile terminal may compare the current remaining power with a preset power threshold, so as to determine whether the current remaining power is smaller than the preset power threshold.
In this step, if the current remaining power is less than the preset power threshold, it may be considered that the current remaining power is small, further, if the current screen state is the expanded state at this time, a problem that the power of the mobile terminal is exhausted soon may occur, accordingly, in order to increase the duration of the mobile terminal as much as possible and avoid the automatic shutdown of the mobile terminal, the mobile terminal may display a folding reminding message when the current remaining power is less than the preset power threshold and the current screen state is the expanded state, where the folding reminding message is used to remind the user to switch the current screen state to the folded state, so as to save the power of the mobile terminal as much as possible, and further, the folding reminding message may be a text type message, or may be a message of a type such as voice, animation, and the embodiment of the present invention does not limit this.
Further, when the folding reminding information is displayed, the mobile terminal may calculate the duration of the mobile terminal when the screen state is the unfolded state based on the historical power consumption speed when the screen state is the unfolded state and the current remaining power, wherein the historical power consumption speed when the screen state is the unfolded state may be calculated in advance based on a historical power consumption curve in the unfolded state, the historical power consumption speed may be stored in the mobile terminal in advance, correspondingly, the mobile terminal may read the historical power consumption speed, then calculate a quotient of the current remaining power and the historical power consumption speed to obtain the duration of the mobile terminal when the screen state is the unfolded state, and then, the mobile terminal may display the duration of the flight and the folding reminding information.
In the embodiment of the invention, the endurance time when the screen state is the unfolding state is determined, and the endurance time and the folding reminding information are simultaneously displayed, so that the user can intuitively determine the endurance time of the mobile terminal under the condition of not switching while prompting the user to switch the screen state to the folding state so as to reduce power consumption, and further the user can select whether to switch according to the actual condition of the user. Furthermore, in an actual application scenario, the duration of the mobile terminal in the folded state can be calculated based on the historical power consumption speed and the current remaining power of the screen in the folded state, and the duration of the mobile terminal in the folded state is displayed at the same time, so that more selection bases can be provided for the user.
