Detailed Description

Prior to the description of the embodiments of the present application, a description will be given of a related art.

The waterfall screen refers to a screen pattern in which two screens are bent downward with an ultra-large curvature. Fig. 1 is a schematic structural diagram of an electronic device equipped with a waterfall screen. In a case where the electronic apparatus is horizontally placed, 1A in fig. 1 is a top view of the electronic apparatus. As shown in fig. 1A, the waterfall screen 10 includes two side bending regions and a middle flat region. The two side bending areas are called waterfall screen areas 11, and the middle straight area is called non-waterfall screen area 12. Fig. 1B is a front view of the electronic apparatus. As shown in fig. 1B, the waterfall screen areas 11 on both sides are bent toward the bottom of the body at an oversized folding angle to wrap both sides of the body, thereby replacing the original frames on both sides.

Due to the bending of the waterfall screen area, the display effect of the area in the landscape mode is not ideal. Therefore, as shown in fig. 2, for an electronic device configured with a waterfall screen, in the vertical screen mode, the display area utilized by the first display window 21 includes a waterfall screen area and a non-waterfall screen area. In the landscape mode, the second display window 22 utilizes a display area including only a non-waterfall screen area, and the waterfall screen area does not display any more picture content.

Based on the display mechanism, in the prior art, when the screen rotation operation is started, as shown in fig. 3A, the electronic device is in the vertical screen mode, and at this time, the screen capture operation is performed on the display screen of the first display window 21, so as to obtain the screenshot 30.

During the screen rotation, the first display window 21 always displays the screenshot 30, as shown in fig. 3B. Meanwhile, the electronic device redraws the first display window 21, and completes coordinate system transformation, so as to obtain a second display window 22 in a landscape mode as shown in fig. 3C.

When the electronic device switches to the landscape mode, as shown in fig. 3C, the electronic device may display a new display on the second display window 22. Since the second display window 22 is not displayed using the waterfall screen area 11, the waterfall screen area 11 may suddenly appear as a graphic "black border" causing visual discomfort to the user.

The present application is proposed to solve the above problems.

According to the method and the device, the display parameters of the waterfall screen area can be dynamically adjusted in the screen turning process, so that the display characteristics of gradual change are presented. Therefore, the phenomenon that the black edge appears in the waterfall screen area suddenly after the mode is switched to the horizontal screen mode can be avoided. The technical solution in the present application will be described below with reference to the accompanying drawings.

Fig. 6 is a schematic scene diagram of the screen turning method provided in the embodiment of the present application, where the scene may be a screen turning scene of an electronic device, and specifically may be a screen turning scene in which the electronic device switches from a vertical screen mode to a horizontal screen mode.

For convenience of understanding, in the following embodiments of the present application, an electronic device having a structure shown in fig. 4 and 5 is taken as an example, and a screen turning method provided in the embodiments of the present application is described with reference to a scenario shown in fig. 6. As shown in fig. 7, the screen turning method provided in the embodiment of the present application includes:

101, the electronic device detects that the screen turn response condition is satisfied.

First, a method of the electronic device determining that the screen turn response condition is satisfied will be described.

In one possible implementation manner, the electronic device may determine whether the screen turning response condition is satisfied according to the posture information of the electronic device.

Specifically, the electronic device can acquire the posture information of the electronic device in real time through the sensor. The types of sensors involved may include, for example, but are not limited to, gyroscope sensors, acceleration sensors, distance sensors, and the like. The electronic equipment can determine that the screen rotation response condition is met after determining that the electronic equipment is in the rotation posture from the vertical screen direction to the transverse screen direction according to the collected posture information.

In another possible implementation manner, the electronic device may determine whether the screen turning response condition is met according to the posture information and the screen turning service setting information.

The screen turning service setting information may specifically include screen turning service setting information of a system level and screen turning service setting information of an application level. Specifically, when the screen turning service setting information at the system level is in the on state, it can be considered that the electronic device system allows the screen turning operation to be performed. Correspondingly, when the screen turning service setting information of the application level is in the open state, the third-party application is considered to be allowed to execute screen turning operation in the using process.

Taking the screen turning service setting information of the system level as an example, the screen turning service setting information may be the setting information of the system "auto-rotation" option. When the "auto-rotate" option is turned on, in one implementation, a user may turn on a setup function, select the "auto-rotate" option, and set it to an on state. In another implementation, as shown in FIG. 8, the user may open the system drop down menu 80 by a gesture operation that slides the screen down from the top box. Then, it can be set to the on state by clicking on the "auto-rotate" button 801 in the pull-down menu.

In the implementation mode, the electronic equipment can further read the screen rotating service setting information after determining that the electronic equipment is in the rotating posture according to the collected posture information. After detecting that the screen turning service setting information is in the opening state, the electronic equipment can determine that the screen turning response condition is met. The step of detecting that the screen turning service setting information is in the on state may include detecting that the screen turning service setting information of the system level is in the on state, or detecting that the screen turning service setting information of the system level and the screen turning service setting information of the application level are in the on state at the same time.

102, the electronic device performs screen capture operation on the display screen of the non-waterfall screen area, and displays the first screen capture on the current screen layer.

After determining that the screen turning response condition is met, the electronic equipment can further execute screen turning response.

Because the coordinate system of the electronic device needs to be changed when the electronic device is switched from the vertical screen mode to the horizontal screen mode, the first display window in the vertical screen mode needs to be redrawn in the screen turning response process, so as to obtain the second display window in the horizontal screen mode. In order to block the disordered layout generated during the layout redrawing of the display window, the embodiment of the application can firstly execute the screen capturing operation on the current display picture in the first display window. Before switching to the landscape mode, a first screenshot obtained by the screenshot operation can be always displayed in the first display window.

Specifically, when the screen capture operation is performed, as shown in fig. 9A in fig. 9, the screen capture operation may be performed only on the non-waterfall screen area 12 of the first display window 21. Thus, when the first cut-out 90 obtained by the screen capture operation is displayed in the first display window 21, the coverage area thereof only includes the non-waterfall screen area 12.

It should be noted that, as shown in fig. 9B in fig. 9, the display layers of the first display window 21 may include a current picture layer 211 and a background layer 212. Wherein the display hierarchy of the background layer 212 is located below the current picture layer 211. The first cut 90 obtained by the screen capture operation may be displayed in the current picture layer 211.

103, the electronic device obtains the rotation angle of the electronic device according to the set period.

In the screen turning process of the electronic equipment, the rotation angle of the electronic equipment can be acquired according to a set period. In one implementation, the current angle information may be obtained using a sensor. Furthermore, the rotation angle of the electronic equipment can be calculated according to the current angle information and the initial angle information of the electronic equipment. The value of the setting period can be flexibly set according to requirements.

1041, the electronic device determines the display parameter of the background layer according to the rotation angle.

And 105, the electronic equipment displays the background layer according to the display parameters.

According to the foregoing description, the coverage of the first screenshot includes only the non-waterfall screen area 12. Therefore, under the condition that the current picture layer and the background layer are displayed in an overlapping mode, the display content of the background layer in the waterfall screen area is not shielded by the current picture layer. Therefore, in the rotation process of the electronic device from the vertical screen mode to the horizontal screen mode, the display state of the waterfall screen area can present a dynamically changing visual effect under the visual angle of a user only by dynamically adjusting the display parameters of the background layer.

In the embodiment of the present application, the display parameter of the background layer may include, but is not limited to, brightness and/or transparency.

Specifically, in some implementations, the rotation angle of the electronic device and the display parameter of the background layer may be in a positive correlation. That is, the larger the rotation angle of the electronic device is, the larger the value of the background layer display parameter is. For convenience of understanding, the embodiments of the present application take transparency as an example, and describe a conversion manner between a rotation angle and a display parameter of a background layer.

In an exemplary implementation, the positive correlation between the rotation angle and the transparency of the background layer may be represented by the following formula:

wherein the content of the first and second substances,

the degree of transparency is indicated and,

indicating the angle of rotation. Wherein the angle of rotation

Can range from 0 ° to 90 °. The value of the transparency is continuously increased along with the increase of the rotation angle. And when the rotation angle reaches 90 degrees, the value of the corresponding transparency reaches 1, and the screen rotating process is finished.

In other implementations, the mapping relationship between the rotation angle and the display parameter may be established in advance. Furthermore, in the rotation process of the electronic equipment, the display parameters corresponding to the current rotation angle can be obtained according to the mapping relation. For the convenience of understanding, the manner of converting between the rotation angle and the display parameter of the background layer is still described by taking transparency as an example.

For example, the mapping relationship between the rotation angle and the transparency may be pre-established as follows: transparency of 30% corresponding to 0 ° to 30 °; transparency of 60% corresponding to 31 ° to 60 °; the transparency was 100% for 61 ° to 90 °. It should be noted that the above is only an exemplary description, and should not be taken as a limitation of the present application.

In the embodiment of the application, because the first screenshot in the current image layer does not cover the waterfall screen area, the display content of the background image layer in the waterfall screen area is not shielded by the current image layer under the condition of superposition display. On the basis, in the screen turning process of the electronic equipment, the display parameters of the background layer are dynamically adjusted according to the change of the rotation angle, the visual experience of dynamic change of the waterfall screen area can be brought to a user, the phenomenon that the waterfall screen area suddenly forms a black edge after the screen turning is finished is avoided, and the user experience is improved.

Fig. 10 is another schematic flow chart of a screen turning method provided in an embodiment of the present application. In another embodiment of the present application, as shown in fig. 10, before performing the step 105, the method may further include:

1042, the electronic device determines a second color value of the background layer according to the first color value of the current picture layer.

In the embodiment of the application, the color value of the background layer can be set according to the color value of the current picture layer.

Specifically, sampling may be performed at a plurality of sampling positions of the current picture layer to obtain a plurality of first color values. The number and the positions of the plurality of sampling positions can be preset. For example, the location range of the several sampling locations may be: and in the non-waterfall screen area, the distance from the non-waterfall screen area to the waterfall screen area is smaller than the area range of a set threshold value.

Then, a second color value of the background layer may be determined according to the plurality of first color values. In one implementation, an average value of the plurality of first color values may be used as the second color value of the background layer.

By the method, the color value of the background image layer is similar to the color value of the current image layer, so that the color contrast between the waterfall screen area and the non-waterfall screen area under the user visual angle is reduced, and the visual experience of the user is further improved.

In another implementation manner, in order to simplify the implementation process and increase the screen turn response speed, the color value of the background layer may also be a preset fixed value. For example, the color may be any color such as black or white, which is not limited in the present application.

In the embodiment of the present application, the execution sequence of step 1041 and step 1042 is not limited. In other implementations, step 1042 may be performed in an order prior to step 1041.

301, the electronic device monitors the attitude information reported by the sensor.

And 302, the electronic equipment determines whether the electronic equipment is in a rotation posture from the vertical screen to the horizontal screen according to the acquired posture information. If yes, go to step 303; otherwise, step 301 is continued.

303, the electronic device determines whether the screen rotation service setting information is in an on state. If so, go to step 304; otherwise, proceed to step 303.

304, the electronic device performs a screen capture operation on the display screen of the non-waterfall screen area, and displays the first screen capture on the current screen layer.

The electronic device 305 acquires its own rotation angle according to a set period.

And 306, the electronic equipment determines the display parameters of the background layer according to the rotation angle.

307, the electronic device determines a second color value of the background layer according to the first color value of the current picture layer.

And 308, the electronic equipment displays the background layer according to the obtained display parameter and the second color value.

In the embodiment of the application, the display hierarchy of the background layer is located below the current picture layer. And the display content of the current picture layer does not cover the waterfall screen area. Based on this, this application is at the commentaries on classics screen in-process, through the display parameter according to rotation angle dynamic adjustment background picture layer, can make waterfall screen region's display state dynamic change, has promoted user's visual experience.

For ease of understanding, fig. 12 shows an example of a scenario of the screen scrolling method provided in the present application, which is used for comparison with the existing screen scrolling scenario shown in fig. 3.

In an exemplary implementation scenario, the display parameter is still taken as transparency, and the aforementioned positive relationship between transparency and rotation angle is taken as an example for description.

As shown in fig. 12A, the electronic device is in the portrait mode, and at this time, a screen capture operation is performed on the display screen of the non-waterfall screen area in the first display window 21, so as to obtain a first screenshot 90. A first screenshot 90 is displayed in the current picture layer 211. At this time, the acquired rotation angle x may be, for example, 10 °. The corresponding transparency y of the background layer 212 is 1/9. Since the first cut-out 90 does not cover the waterfall screen area 11, in the case of the overlay display, the display state of the waterfall screen area 11 coincides with the background layer 212, which may be light gray as shown in 12A in fig. 12, for example.

During the screen rotation, the first display window 21 always displays the first cut 90, as shown in 12B in fig. 12. The rotation angle x acquired again may be 45 °, for example. At this time, the transparency y of the background image layer 212 is 1/2. Since the first cut-off image 90 does not cover the waterfall screen area 11, in the case of the overlay display, the display state of the waterfall screen area 11 coincides with the background image layer 212, and may be dark gray as shown in 12B in fig. 12, for example.

When the electronic device switches to the landscape mode, as shown in fig. 12C, the electronic device may display the display screen 91 in the landscape mode on the second display window 22. The acquisition rotation angle x may be 90 °, for example. At this time, the transparency y of the background image layer 212 takes a value of 1. Since the display screen 91 is not displayed using the waterfall screen area 11, in the case of the overlay display, the display state of the waterfall screen area 11 coincides with the background layer 212, and may be black as shown in 12C in fig. 12, for example.

Therefore, compared with the screen turning scene shown in fig. 3, based on the technical scheme of the application, the display effect of the waterfall screen area can be dynamically changed along with the change of the rotation angle of the electronic equipment, and visual discomfort caused by sudden change of the waterfall screen area after the screen turning is finished is avoided.

On the basis of the software structure block diagram shown in fig. 5, fig. 13 shows another flowchart of the screen turning method provided by the present application. As shown in fig. 13, a screen turning method provided in an embodiment of the present application may include:

401, the direction calculating unit monitors the direction information of the electronic device reported by the sensor unit.

In the embodiment of the application, the direction calculation unit located in the application framework layer can monitor the direction information reported by the sensor unit located in the system layer in real time. The direction information reported by the sensor unit may be received from a sensor driver (not shown in fig. 13) located in the kernel layer. The direction calculation unit may determine whether the electronic device is in a rotational posture according to the received direction information. Step 402 may be further performed upon determining that the electronic device is in a rotational position.

The direction calculation unit reads the screen rotation service setting information from the direction setting unit 402.

The direction setting unit positioned in the application program layer can store the screen turning service setting information of the application program. The direction calculation unit may obtain the service transfer setting information of the current application program from the direction setting unit after determining that the electronic device is in the rotation posture.

And 403, determining that the screen turning response condition is met according to the screen turning service setting information and the direction information by the direction calculation unit.

In the embodiment of the application, after the electronic equipment is determined to be in the rotating posture according to the direction information, the fact that the user has the screen rotating requirement can be shown. On the basis, if the direction calculation unit determines that the screen turning service setting information is in the on state, the screen turning service setting information indicates that the current application program allows screen turning. At this time, the direction calculation unit may determine that the screen turn response condition is satisfied.

The direction calculation unit sends 404 a window drawing instruction to the window drawing unit.

After determining that the screen rotation response condition is satisfied, the direction calculation unit may send a window drawing instruction to a window drawing unit located at the application layer. The window drawing instruction can be used for instructing the window drawing unit to redraw the display window, so that the first display window in the vertical screen mode is converted into the second display window in the horizontal screen mode. Meanwhile, the window drawing instruction may also be used to instruct the window drawing unit to freeze the screen. Freezing the screen means that the window drawing unit stops receiving the input event and keeps the current screen display content unchanged.

The window drawing unit performs window redrawing according to the window drawing instruction 405, and freezes the screen.

406, the direction calculation unit sends a screen capture instruction to the window control unit.

The direction calculation unit may also send a screen capture instruction to a window control unit located at the application framework layer. The screen capture instruction can be used for instructing the window control unit to capture the screen of the display content of the current picture layer in the display window.

And 407, the window control unit performs screen capture operation on the display content of the current picture layer to obtain a first screenshot.

Specifically, the window control unit may call an animation control unit (not shown in fig. 13) located in the application framework layer, and capture the display content of the current picture layer through the animation control unit. In the embodiment of the application, the screen capture range only includes a non-waterfall screen area of the current picture layer. In the screen conversion process, the obtained first screenshot can be always displayed on the current picture layer and is used for shielding the disordered layout generated in the window redrawing process.

408, the direction calculating unit periodically obtains the direction information of the electronic device reported by the sensor unit.

409, the direction calculating unit determines the display parameters of the background layer according to the direction information of the electronic equipment.

The direction calculation unit may determine a rotation angle thereof according to the direction information of the electronic device. Furthermore, the display parameters of the background layer can be obtained according to the relationship between the rotation angle and the display parameters. For the specific calculation method, reference may be made to the foregoing embodiments, which are not described herein again.

And 410, the direction calculation unit sends the display parameters of the background layer to the window control unit.

And 411, the window control unit sends the display parameters of the background layer and the display parameters of the current picture layer to the layer mixing unit.

In a specific implementation process, the window control unit may invoke an animation control unit (not shown in fig. 13), and convert the display parameters of the background layer and the display parameters of the current picture layer into a data format that can be recognized by the layer mixing unit located in the system layer through the animation control unit. The format-converted display parameters may then be sent to the layer blending unit.

It should be noted that, in the actual execution process, the parameter information sent to the layer mixing unit may further include a plurality of display-related information such as window position information, window size information, and layer level information.

And 412, the layer mixing unit executes layer mixing and sends the mixed display data to the display driver for displaying.

In this embodiment of the present application, the layer mixing unit may perform layer mixing on the background layer and the current picture layer according to the received display parameter. Wherein, the display hierarchy of the background layer is positioned below the current picture layer.

Then, the layer mixing unit may send the mixed display data to a three-dimensional graphics processing unit of the system layer. The three-dimensional graphic processing unit can write the received display data into the memory of the electronic equipment.

Furthermore, the display driver in the kernel layer can display the background layer and the current picture layer by reading the display data in the memory. During specific display, according to the foregoing description, since the coverage area of the first screenshot only includes the non-waterfall screen region, the display content of the background layer in the waterfall screen region is not blocked by the current image layer when the current image layer and the background layer are displayed in a superimposed manner.

According to the method and the device, in the screen turning process of the electronic equipment from the vertical screen mode to the horizontal screen mode, the direction calculating unit located on the application program frame layer can dynamically adjust the display parameters of the background layer according to the direction information of the electronic equipment. The layer mixing unit located in the system layer can mix the background layer and the current picture layer according to the dynamically changed display parameters. Because the first screenshot of the current image layer does not cover the waterfall screen area, the display state of the waterfall screen area can present a dynamically changing visual effect under the visual angle of a user.
