Referring to fig. 1 to fig. 3, a terminal 100 in the embodiment of the present application includes a housing assembly 10, a flexible display 30, a driver 50, and a driving mechanism 70. The shell assembly 10 is a hollow structure; the components of the driver 50, the drive mechanism 70, and the camera 60 may all be disposed in the housing assembly 10.

The first housing 12 and the second housing 14 are relatively far away from each other, and the driving member 50 can drive the flexible display 30 to unfold, so that more flexible display 30 is exposed out of the accommodating space 16. The flexible display 30 exposed to the outside of the accommodating space 16 is illuminated so that a display area presented by the terminal 100 becomes large.

Referring to fig. 6, a flowchart of a display method of a user interface provided in an exemplary embodiment of the present application is shown. The embodiment is described by taking the method as an example executed by the terminal shown in fig. 1 to 5, and the process includes the following steps:
Because the exposed display area of the flexible display screen can change along with the relative movement of the shell in the embodiment of the application, the terminal needs to acquire the resolution of the current exposed display area of the flexible display screen, so as to determine whether the current resolution needs to be adjusted or not in the following process.
In a possible implementation manner, the terminal operating system provides an interface for an application program to call (which may be a native application program or a third-party application program), and when an application program (i.e., a current application) running in a foreground has a specific requirement on the screen resolution, the application program calls the interface to request to acquire the current screen resolution, so as to execute a subsequent resolution adjustment process.
In a possible implementation manner, the terminal obtains a current screen size of a currently exposed display area of the flexible display screen, and then determines the current screen resolution according to the complete screen size, the complete screen resolution and the current screen size of the flexible display screen. Illustratively, the current screen resolution is (current screen size/full screen size) × full screen resolution. The embodiment of the present application does not limit the specific manner of acquiring the screen resolution.
In one possible implementation, when the exposed display area of the flexible display screen is at the target screen resolution, the area ratio of the interface filling area in the user interface (of the current application) is lower than the area ratio of the interface filling area in the user interface when the exposed display area of the flexible display screen is at the current screen resolution. The interface filling area is an area outside the area where the interface elements are located in the user interface and is used for filling the vacancy after the interface elements are laid out. For example, the interface fill area is a black fill area in the user interface.
Illustratively, as shown in fig. 7, the current application is a shooting application, and the user interface 71 (i.e., shooting interface) includes a status bar element 711 (for displaying a series of status controls, such as a flash control, a camera setting control, and the like), a shooting preview element 712, and a control bar element 713 (including, for example, a shutter control, a view control, and a shot-cut control). In order to fill in the area other than the interface element, the user interface 71 further includes interface filling areas 714 above and below the shooting screen preview element 712.
In one possible embodiment, the target screen resolution is determined by the current application, and the target screen resolution may be different in different scenarios. For example, when the photo taking sizes are 1080 × 1080(1:1) and (1920 × 1080)16:9, the target screen resolutions of the photographing applications are different.
Optionally, after the current screen resolution and the target screen resolution are obtained, the terminal detects whether the current screen resolution and the target screen resolution are consistent, and if the current screen resolution and the target screen resolution are consistent, the terminal indicates that the currently applied display effect is optimal under the current screen resolution, so that the current screen resolution is maintained; if the two are not consistent, it is indicated that the area occupation ratio of the interface filling area in the user interface is too high under the current screen resolution, and at this time, the terminal needs to adjust the current screen resolution.
Different from the fact that the screen size and the screen resolution of the terminal in the related technology are fixed, the screen size and the screen resolution of the terminal in the embodiment of the application can be changed along with relative movement of the shell, therefore, when the screen size and the screen resolution are not consistent, the terminal can control the flexible display screen to stretch and contract according to the target screen resolution, the screen resolution of an exposed display area of the flexible display screen reaches the target screen resolution, and the area ratio of an interface filling area in a user interface is further reduced.
In a possible implementation mode, the terminal controls the first shell and the second shell to move relatively to change the size of the exposed display area of the flexible display screen, so that the effect of adjusting the resolution of the screen is achieved. Wherein the relative movement of the first housing and the second housing is controlled by the terminal through the driving mechanism.
Optionally, the terminal controls the first shell and the second shell to move away from each other through the driving mechanism, so that the flexible display screen is stretched; the first shell and the second shell are controlled to move through the driving mechanism, and the flexible display screen is contracted.
After the flexible display screen is stretched, the terminal displays the user interface in the current exposed display area, and the display effect of the user interface is optimized.
Illustratively, as shown in fig. 7, since the resolution of the shooting screen preview element 712 is 1080 × 1080, the shooting screen preview element 712 cannot completely fill the user interfaces other than the status bar element 711 and the control bar element 713, and at this time, the empty area needs to be filled in by the interface filling area 714. By adopting the method provided by the embodiment of the application, the terminal can control the flexible display screen to shrink according to the corresponding target screen resolution in the current shooting mode because the height of the flexible display screen is variable, and display the user interface 71 in the shrunk flexible display screen, so that the interface filling area 714 in the user interface 71 is eliminated. After the flexible display screen is stretched, the influence of an interface filling area on a user interface is eliminated, meanwhile, an exposed display area of the flexible display screen is reduced, and the screen display power consumption of the terminal is reduced while the user can conveniently control the flexible display screen with one hand.
To sum up, in the embodiment of the present application, because the terminal has the flexible display screen, and the two parts of shells relative motion through control terminal can change the exposed display area of flexible display screen, consequently when current screen resolution is different with the target screen resolution of current application, the terminal can stretch out and draw back according to target screen resolution control flexible display screen, and show the user interface of current application in flexible display screen, thereby reduce the area ratio in the interface filling area among the user interface, realize the dynamic adaptation of screen resolution and application resolution, and then reduce the influence of interface filling area to the display effect, the display effect of user interface has been optimized.
Referring to fig. 8, a flowchart of a display method of a user interface provided in another exemplary embodiment of the present application is shown. The embodiment is described by taking the method as an example executed by the terminal shown in fig. 1 to 5, and the process includes the following steps:
The step 601 can be referred to in the implementation manner of this step, and this embodiment is not described herein again.
Regarding the manner of determining the target screen resolution corresponding to the user interface, in a possible implementation manner, when determining the target screen resolution of the user interface, the terminal obtains the element layout of each interface element in the user interface corresponding to the current application and the interface element resolution of each interface element. Wherein the interface element layout may be an absolute layout or a relative layout of the interface element in the user interface.
Optionally, the element layout and interface element resolution may be provided to the terminal operating system by the current application. In other possible embodiments, the process of determining the target screen resolution may also be performed by the current application, and the target screen resolution is directly provided to the terminal operating system by the current application. This embodiment is not limited to this.
Illustratively, the resolution of an interface element corresponding to a status bar element in a shooting interface obtained by the terminal is 1080 × 150, the resolution of an interface element corresponding to a shooting picture preview element is 1080 × 1080, the resolution of an interface element corresponding to a control bar element is 1080 × 350, the layout of an interface element corresponding to a status bar element is the top of the user interface, the layout of an interface element corresponding to a control bar element is the bottom of the user interface, and the layout of an interface element corresponding to a shooting picture preview element is between a status bar element and a control bar element.
And 803, determining the target screen resolution corresponding to the current application according to the interface element layout and the interface element resolution.
Further, the terminal determines respective resolutions of the screen area in height and width at the time of the optimal display effect according to the interface element layout and the interface element resolution, so as to determine the target screen resolution. Wherein, the current screen resolution and the target screen resolution are resolutions in the flexible display screen expansion and contraction direction (i.e. the direction of relative movement with the shell).
In a possible implementation manner, the terminal determines a target lateral resolution according to the lateral layout of each interface element and the lateral resolution of the interface element; and determining the target longitudinal resolution according to the longitudinal layout of each interface element and the longitudinal resolution of the interface element.
With reference to the example in the above step, when the interface element layout indicates that the status bar element, the captured picture preview element, and the control bar element in the captured interface are located at the same longitudinal position and at different lateral positions, the terminal determines a maximum value of resolutions in respective corresponding lateral resolutions of the status bar element, the captured picture preview element, and the control bar element as a target lateral resolution, that is, the target lateral resolution is 1080; the sum of the respective corresponding longitudinal resolutions of the status bar element, the captured picture preview element, and the control bar element is determined as the target longitudinal resolution, that is, the target longitudinal resolution is 150+1080+350 — 1580. Accordingly, the target screen resolution is 1080 × 1580.
It should be noted that the above embodiments are only described by taking a shooting interface of a camera application as an example, and the specific calculation method and the interface element layout method of the user interface are not limited.
Step 804, in response to that the current screen resolution is different from the target screen resolution corresponding to the current application, determining the current screen size and the target screen size corresponding to the target screen resolution.
Because the screen resolution of the exposed display area of the flexible display screen is closely related to the size of the exposed display area, and the terminal dynamically adjusts the screen resolution by adjusting the size of the exposed display area, before the terminal controls the flexible display screen to stretch, the stretching amount of the flexible display screen can be obtained according to the current screen size and the target screen size.
In one possible implementation, the terminal determines a current screen size according to the current screen resolution and determines a target screen size according to the target screen resolution, wherein the current screen size and the target screen size are sizes in a flexible display screen expansion and contraction direction (i.e. a relative movement direction with the housing).
Illustratively, the current screen size is (current screen resolution/full screen resolution) × full screen resolution, and the target screen resolution is (target screen size/full screen size) × full screen resolution.
For example, the full screen resolution of the flexible display screen is 2600 (the minimum screen resolution is 1080), the corresponding full screen size is 13cm (the minimum screen size is 8cm), and if the current screen resolution is 1920, the current screen size is (1920/2600) × 13 ═ 9.6 cm; if the target screen resolution is 1580, the current screen size is (1580/2600) × 13 ═ 7.9 cm.
In a possible implementation mode, the terminal determines a telescopic distance and a telescopic mode according to the current screen size and the target screen size, so that a telescopic instruction which can be identified by the screen mechanical assembly is generated, the screen control assembly controls the shell to move relatively, and the flexible display screen is telescopic. Wherein the expansion and contraction mode comprises expansion (the exposed display area is increased) and contraction (the exposed display area is reduced).
Optionally, the screen mechanical assembly is a drive mechanism 70 as shown in fig. 4.
Alternatively, the expansion command may be a Pulse Width Modulation (PWM) signal for controlling the rotation of the motor.
In one possible embodiment, the step comprises the steps of:
the method comprises the steps of firstly, determining a telescopic distance and a telescopic mode according to a first size in current screen sizes and a second size in target screen sizes, wherein the first size and the second size are screen sizes in the relative movement direction of a shell.
Since the flexible display screen can only be extended and retracted in the extension and retraction direction (the relative movement direction of the housing), the extension and retraction command generated by the terminal is used for instructing the housing to extend and retract a predetermined distance in a specified extension and retraction manner.
Optionally, the terminal obtains a first size of the current screen size in the telescopic direction and a second size of the target screen size in the telescopic direction. If the first size is larger than the second size, the telescopic mode is determined to be contraction, if the first size is smaller than the second size, the telescopic mode is determined to be extension, and the telescopic distance is the difference value between the first size and the second size.
In connection with the above example of steps, since the first dimension 9.6cm is larger than the second dimension 7.9cm, the terminal determines the telescoping distance to be 1.8cm and the telescoping manner to be telescoping.
And secondly, generating a telescopic instruction according to the telescopic distance and the telescopic mode.
In a possible implementation manner, the terminal determines the rotation direction of the screen mechanical assembly according to the telescopic mode, and determines the rotation distance according to the telescopic distance, so as to generate the telescopic instruction.
For example, in the configuration shown in fig. 5 in combination with the above example, the expansion/contraction command generated by the terminal instructs the drive mechanism 70 to rotate counterclockwise by a rotation distance of 1.8 cm.
After the telescopic instruction is generated, the terminal sends the telescopic instruction to the screen mechanical assembly, and the screen mechanical assembly controls the flexible display screen to be telescopic according to the telescopic mode and the telescopic distance indicated by the telescopic instruction, so that the size of an exposed display area of the telescopic display screen is the size of a target screen.
In a possible implementation manner, if the current screen resolution is different from the target screen resolution, the terminal displays a size adjustment control on the user interface, and when receiving a trigger operation on the size adjustment control in the user interface (indicating that a screen size adjustment requirement exists), the terminal sends a telescopic instruction to the screen mechanical assembly.
Illustratively, as shown in fig. 9, the terminal displays a resizing control 715 in the user interface 71, and when a clicking operation on the resizing control 715 is received, the terminal sends a scaling instruction to the screen mechanical assembly, so as to control the flexible display screen to shrink, thereby eliminating an interface filling area 714 above and below the shooting preview picture element 712.
In another possible implementation, the user may trigger the screen resizing by actively performing a zoom operation. Optionally, when the flexible display screen is subjected to telescopic operation and the telescopic mode indicated by the telescopic operation is consistent with the telescopic mode indicated by the telescopic instruction, the telescopic instruction is sent to the terminal screen mechanical assembly. And if the telescopic mode indicated by the telescopic operation instruction is not consistent with the telescopic mode indicated by the telescopic instruction, the terminal responds to the telescopic operation of the user without sending the telescopic instruction.
Illustratively, in an example of the above step, if the telescopic mode indicated by the telescopic operation is telescopic, the terminal sends a telescopic instruction to the screen mechanical assembly; if the telescopic mode indicated by the telescopic operation is extension, the terminal cannot send a telescopic instruction to the screen mechanical assembly.
Of course, in addition to the above two ways of triggering to send the telescopic instruction, the telescopic instruction may also be triggered by voice, gesture, or the like, which is not limited in this embodiment.
The image drawn by the terminal is stored in a display buffer (referred to as a display memory for short), and the display buffer is kept unchanged for the terminal with fixed screen size and resolution.
In addition, in order to adapt to the change of the screen resolution, the window attribute of the user interface is also changed correspondingly, so the terminal also needs to synchronously adjust the application window attribute.
In a possible implementation manner, if the resolution of the target screen is greater than the resolution of the current screen, the terminal adjusts the display buffer up, and if the resolution of the target screen is less than the resolution of the current screen, the terminal adjusts the display buffer down. In addition, the terminal adjusts the window size of the application window to match the target screen resolution.
And 808, adjusting the interface element layout of the interface elements in the user interface according to the display cache and the application window attributes, and redrawing the user interface.
Further, the terminal adjusts the interface element layout of the interface elements in the user interface according to the adjusted application window attribute and redraws the user interface; after the user interface is redrawn, the image data corresponding to the user interface is written into the adjusted display cache, so that the image data in the display cache is sent to the flexible display screen for the flexible display screen to display in the subsequent display process.
And step 809, displaying the redrawn user interface in the flexible display screen after stretching.
And finally, the terminal displays the redrawn user interface in the flexible display screen after stretching.
In this embodiment, the terminal determines the flexible distance and the flexible mode of the flexible display screen based on the current screen size and the target screen size, so as to generate a corresponding flexible instruction, instruct the screen mechanical assembly to control the flexible display screen to stretch according to the flexible instruction, and improve the accuracy of screen stretching. Meanwhile, the terminal adopts a control triggering mode or a manual telescopic triggering mode, telescopic instruction sending is achieved, and the influence of screen stretching directly performed by the terminal on user use is avoided.
In addition, in this embodiment, the terminal determines the optimal screen resolution (i.e., the target screen resolution) of the user interface based on the layout and resolution of the interface elements in the user interface, and further performs screen dynamic adjustment, display cache adjustment, and user interface redrawing according to the optimal screen resolution, thereby ensuring normal display of the user interface after the screen is stretched.
In another possible application scenario, as shown in fig. 9, the current application is a video application, and the resolution of the currently played video 1001 in the playing interface is 1920 × 1080. However, since the resolution of the exposed display area of the current flexible display screen is 1500 × 1080, the picture of the currently playing video 1001 is compressed and displayed in the playing interface, and there are black borders 1002 above and below the playing interface. In order to improve the video display effect, the terminal determines that the flexible display screen needs to be extended according to the current screen resolution 1500 × 1080 and the target screen resolution 1920 × 1080, wherein the extension distance is 1cm, and then the flexible display screen is controlled to be extended and retracted through the screen mechanical assembly, so that the resolution of the flexible display screen after extension and retraction is 1920 × 1080. After the screen is stretched, the currently played video 1001 can be displayed in the playing interface in full resolution, and the influence of upper and lower black edges on video watching is avoided.
When the resolution of the target screen is smaller than that of the current screen, the terminal can reduce the influence of an interface filling area on a user interface and can also reduce the display power consumption by reducing the exposed display area of the flexible display screen; however, when the target screen resolution is smaller than the current screen resolution, since the exposed display area of the flexible display screen increases after stretching, the display power consumption of the terminal increases. Therefore, in a possible implementation manner, if the current screen resolution is different from the target screen resolution, the terminal further compares whether the target screen resolution is higher than the current screen resolution, and if so, acquires the power state of the terminal. Wherein the terminal power state comprises a (remaining) power and a charge-discharge state.
Optionally, if the electric quantity state indicates that the electric quantity is higher than the electric quantity threshold value or in a charging state, the terminal controls the flexible display screen to stretch according to the resolution of the target screen; if the electric quantity state indicates that the electric quantity is lower than the electric quantity threshold value or is not in a charging state, the terminal keeps the resolution ratio of the current screen, and the phenomenon that the electric quantity is consumed too fast after the display area of the flexible display screen is enlarged is avoided.
For example, the charge threshold is 50%. This embodiment is not limited to this.
In this embodiment, when the current screen resolution is lower than the target screen resolution, the terminal determines whether to adjust the screen resolution according to the power state of the terminal, so as to avoid the problem that power consumption is too fast due to the fact that the screen resolution is improved when the remaining power is too low.
In addition, since not all applications have high requirements for screen resolution, for example, video playing, picture previewing and shooting applications have high requirements for screen resolution, and e-book, news reading, shopping and audio playing applications have low requirements for screen resolution. Therefore, in a possible implementation manner, the terminal acquires the application type of the current application, detects whether the application type belongs to a preset application type, and if so, executes the adjustment process of acquiring the current screen resolution and the subsequent screen resolution; if not, the terminal keeps the current screen resolution. Wherein the preset application type includes at least one of a photographing application, a video application, a short video application, and an album application.
Of course, other applications related to pictures, video displays and shooting can be classified as preset application types, and the embodiments of the present application are not limited thereto.
Optionally, if the application type does not belong to the preset application type, the terminal controls the flexible display screen to shrink to the minimum size, so that power consumption of the terminal is reduced. For example, if the current application is a music playing application, the terminal controls the flexible display screen to shrink to the minimum size, so that the normal use of the application is not influenced, and the power consumption of the terminal can be reduced.
