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.
In order to solve the problems in the related art, embodiments of the present invention provide an information display method and apparatus, an electronic device, and a storage medium, so as to solve the problem that in a dual-screen electronic device, a front screen cannot preview content displayed on a back screen.
The principle of information display of an operating system, such as an Android system, in an electronic device is as follows, first, each interface display resource is stored in a respective layer component surface. Then, the surfaces are mixed to finally obtain a total surface, the total surface is put into a Frame Buffer memory (fb), and then, under the support of the bottom layer Frame Buffer memory drive, a display screen controller (displayControl) can continuously take out resources in surfcae from the fb, namely colors which are required to be displayed by corresponding to one pixel point, so as to display the colors in a mode of refreshing the screen of the electronic device.
Based on this, the information display method provided by the embodiment of the invention can be applied to electronic equipment which is provided with double-sided screens, namely a first screen and a second screen which are oppositely arranged.
Fig. 1 is a schematic diagram of an information display architecture according to an embodiment of the present invention.
As shown in fig. 1, here, in order to make the display of the first screen and the second screen of the double-sided screen completely independent. Therefore, in the embodiment of the present invention, the surfaces related to the first screen and the second screen are distinguished, that is, the first surface related to the first screen may include surface11, surface12 … … surface1N, where N is a positive integer, and the second surface related to the second screen, where the second surface includes surface21, surface22 … … surface2M, and M is a positive integer. Then two fb's are needed, i.e. a first screen is associated with the first frame buffer fb1 and a second screen is associated with the second frame buffer fb 2. The electronic device may further include a first displayControl corresponding to the first screen and a second displayControl corresponding to the second screen. Here, a first displayControl is associated with fb1 and a second displayControl is associated with fb2, where the association of a first screen with fb1 may represent that fb1 stores the resources displayed on the first screen and the second screen is associated with fb2 for the same reason. The association of the first displayControl with fb1 may represent that the first displayControl acquires a resource in fb1 and displays the resource on the first screen, and the second screen, fb2, is associated with the second displayControl for the same reason.
It should be noted that, in the embodiment of the present invention, in addition to the above-mentioned two fbs, the two fbs may be two sub-fbs of one frame buffer memory, or may be two separate frame buffer memories, and the embodiment of the present invention does not limit the number and the structure of the frame buffer memories in the electronic device.
Therefore, based on the above framework, in order to display the content to others through the second screen, the first screen is independent in display, and the user can preview the scene of the display content of the second screen through the first screen. In the embodiment of the present invention, by receiving a first input of a user on a first screen, in response to the first input, a first displayControl acquires a target resource from a second frame buffer memory, that is, a second fb, and displays target information displayed on a second screen on the first screen according to the target resource.
Based on this, the embodiment of the present invention provides a method for displaying information, which can be specifically described in detail with reference to fig. 2.
Fig. 2 is a flowchart of an information display method according to an embodiment of the present invention.
As shown in fig. 2, the information display method may include: first, step 210, receiving a first input on a first screen; then, step 220, in response to the first input, obtaining the target resource from the second frame buffer memory; then, in step 230, target information corresponding to the target resource is displayed on the first screen according to the target resource.
Therefore, when the back screen displays information to others, the front screen can preview the back screen, and the synchronization of the display information of the front screen and the back screen can also be realized.
Optionally, the electronic device further comprises: a first display screen controller associated with the first screen and a second display screen controller associated with the second screen, the retrieving a target resource from the second frame cache memory in response to the first input, comprising: in response to the first input, the first display screen controller retrieves a target resource from the second frame buffer memory.
The above steps 210 to 230 are explained in detail as follows:
first, referring to step 220, in the embodiment of the present invention, based on two display scenes, a manner of obtaining target resources corresponding to the two display scenes is provided, specifically as follows:
scenario 1, as shown in fig. 3, if the first input is used to indicate that the target information is displayed in a full-screen display manner on the first screen 10, this step 220 may include retrieving the target resource from the second frame buffer.
In scenario 2, as shown in fig. 4, if the first input is used to indicate that the target information is displayed in a partial display manner in the first display window, i.e. the floating window 11, on the first screen 10, step 220 requires to obtain the first resource from the first frame buffer memory in addition to the target resource from the second frame buffer memory; the first resource is a resource corresponding to the first information displayed on the first screen, so that the first information and the target information can be displayed on the first screen at the same time.
For example, a floating window 11, that is, a small window related to the second screen, may be added to the first screen, and a plurality of surfaces 21 and 22 … … surfaces 2M related to the second screen are mixed to generate the second surface. And associating the second surface with the second screen small window, so that the second surface of the second screen small window, namely the total surface obtained by fusing all the contents displayed by the second screen with the first surface related to the first screen, can enable the first screen to display the display information containing the resources of the second screen. Thereby, the display content of the second screen can be seen by the first screen through the floating window 11, and the display of the first screen is independent and does not influence the second screen.
In addition, the floating window 11 can also be enlarged or reduced, i.e. can fill the entire first screen, such as scene 1. In this way, information on the second screen can also be displayed simultaneously on the first screen.
Then, referring to step 230, based on scenario 2 in step 220, in order to implement simultaneous display of the first information and the target information on the first screen, in a possible embodiment, step 230 may specifically include:
under the condition that the first screen comprises a first display window and a second display window, associating a second frame cache memory with the first display window, and displaying target information in the first display window; associating the first frame buffer memory with the second display window, and displaying the first information in the second display window; the first information is information corresponding to a first resource in the first frame buffer memory. The first display window and the second display window can be displayed in a split screen mode or a floating window mode.
It should be noted that, in the embodiment of the present invention, in addition to the above-mentioned scene 1 and scene 2, it can be implemented that the first screen is independent from the second screen, the target information on the second screen is transmitted through the first display area, and the target information in the first display area can also be operated. For example, when a user wants to have the first screen and the second screen fully linked, i.e., what the first screen displays and what the second screen displays are fully synchronized; alternatively, the second screen synchronizes exactly the same operation as to how the first screen operates. The above scenarios can all be implemented by the first screen and the second screen sharing the same fb, that is, when the content of the first screen and the content of the second screen are to be displayed through the first screen, the first displayControl may access both the first fb and the second fb; conversely, when the contents of the first screen and the second screen are displayed through the second screen, the second displayControl may access the first fb as well as the second fb.
Based on the above operation on the target information in the first display area, the embodiment of the present invention provides the following possibilities, which are specifically shown below.
In another possible embodiment, as shown in fig. 5, when the user moves the first information in the second display window 12 to the first display window 11 and wants to display the first information on the second screen, after step 230, the method may further include:
receiving second input of the first information and the target information by the user; updating the resources stored in the first frame buffer memory and the second frame buffer memory in response to the second input; acquiring a second resource from a second frame buffer memory; and displaying second information corresponding to the second resource on the second screen according to the second resource. Here, the second input in the embodiment of the present invention may include operations such as moving, exchanging, and the like of the first information and the target information. In addition, the step involves updating the resources stored in the first frame buffer memory and the second frame buffer memory, which may be updating the first frame buffer memory, which may be updating the second frame buffer memory, which may be updating the resources stored in the first frame buffer memory and the second frame buffer memory. The second resource in the embodiment of the present invention may include the first resource and the target resource.
In addition, when the second information is displayed on the second screen, whether the display contents of the first display window and the second display window are updated or not can be determined according to the second information displayed on the second screen, and if the display contents of the first display window and the second display window are updated, the display contents of the first display window and the second display window are updated.
It should be noted that, as shown in fig. 6, the display sizes of the first display window 11 and the second display window 12 according to the embodiment of the present invention may be adjusted according to actual situations. Thus, after step 230, a third input to the first display window by the user is received; in response to a third input, a display size of the first display window and/or the target information on the first screen is changed. Alternatively, in response to a third input, the display size of the second display window and/or the first information on the first screen is changed.
For example, in a scenario, when the target information is displayed through the first display window, a part of the area of the first screen for displaying the first information is occupied, and thus, the first surface' mixed after the part of the surface in the first screen is cancelled is placed in the first fb. Then, the underlying display driver is modified, and if the target information is displayed through the first display window and the first information is displayed through the second display window, the first displayControl may obtain the second surface in the second fb to display the target area in the first display window, and obtain the first surface' in the first fb to display the first information in the second display window. Otherwise, the second screen works the same way. Therefore, the content of the pixel points collected and refreshed by the first screen and the second screen is completely consistent, so that complete cooperation is realized, and synchronous display of the front screen and the back screen is realized.
In yet another possible embodiment, when the user wants to perform a modification operation, an addition operation, a deletion operation, and a download operation on the target information displayed on the second screen through the first display window in the first screen, the method may further include the following possibility.
(1) Receiving a third input of a user for modifying third information in the first information on the first screen under the condition of modifying the target operation;
in response to a third input, modifying a third resource in the first frame buffer memory corresponding to the third information and sending the third resource into the second buffer memory;
and updating the first resource in the second cache memory according to the third resource, and displaying first information corresponding to the updated first resource of the second frame cache memory in the second screen.
(2) Receiving a fourth input of a user for deleting fourth information in the first information on the first screen under the condition of deleting the target operation;
in response to a fourth input, deleting a fourth resource corresponding to the fourth information in the first frame buffer memory, and sending location information of the deleted fourth resource to the second buffer memory;
and updating the first resource in the second cache memory according to the position information, and displaying the first information corresponding to the updated first resource of the second frame cache memory in the second screen.
At this time, the second cache memory already stores the first resource corresponding to the first information, so that, when the location information of deleting the fourth resource is received, the first resource in the second cache memory can be updated according to the location information of deleting the fourth resource.
(3) Receiving a fifth input that a user adds fifth information to the first information displayed on the first screen in the case of performing an adding operation on the target operation;
in response to a fifth input, adding a fifth resource corresponding to the fifth information in the first frame buffer memory, and sending the position information of the added fifth resource and the fifth resource to the second buffer memory;
and updating the first resource in the second cache memory according to the position information, and displaying the first information corresponding to the updated first resource of the second frame cache memory in the second screen.
(4) And in the case that the target operation is a downloading operation, determining a sixth resource for downloading the sixth sub information in the second frame buffer memory, and sending the sixth resource to the first frame buffer memory.
Here, in the 4 cases mentioned above, the content displayed on the first screen may be transmitted to the second screen so that the second screen displays the content. According to the principle, the station team is modified by the surface12 corresponding to the first screen, namely the station team is switched to the second screen surface queue, so that the information displayed on the first screen can be quickly sent to the second screen for display, and if the operation of double-click of the double finger joints of a user is received in a recent task card scene, the information displayed on the first screen can be quickly sent to the second screen for display; or, as in the desktop application scenario, when a double-finger joint double-click application is received, the split body of the application is displayed on the second screen, and the first screen operates the application main body, and the like. Similarly, the second screen can be operated in such a way that the split of the application program is displayed on the first screen.
Therefore, in the embodiment of the present invention, different frame buffer memories are respectively set for the first screen and the second screen of the dual-sided screen, that is, the first screen is associated with the first frame buffer memory, and the second screen is associated with the second frame buffer memory, where the first frame buffer memory and the second frame buffer memory store resources corresponding to information displayed on the dual-sided screen. Then, responding to a first input of a user on a first screen, and acquiring a target resource from a second frame cache memory; and displaying target information corresponding to the target resource on the first screen according to the target resource. Therefore, when the information is displayed to others by using the back screen, the situation of the back screen can be previewed by the front screen, and the synchronization of the display information of the front screen and the back screen can also be realized.
