The following describes in detail the split-screen display method in the embodiment of the present invention.
Fig. 2 is a schematic flow chart of a split-screen display method in an embodiment of the present invention, and referring to fig. 2, the split-screen display method may include:
s201: and obtaining the content to be displayed.
The display content refers to display data corresponding to a user interface displayed on a display screen, and the content to be displayed refers to display data corresponding to a user interface which a user needs to display on the display screen, and the display data are data in an application program.
Specifically, in the smart phone, the content to be displayed is display data corresponding to different APPs, for example: the display data of WeChat, Youkou, Taobao, and the like, and correspondingly, the display screen displays a chat interface, a video interface, a commodity interface, and the like. In a personal computer, the contents to be displayed are display data corresponding to different software, such as: the display data of the search browser, the display data of the flight video, the display data of Office software and the like are displayed on the display screen, and correspondingly, the interface of a webpage, the interface of a video, the interface of Word and the like are displayed on the display screen. The specific content of the content to be displayed is not limited herein.
It should be noted that, when a user starts an application program, the processor can receive display data corresponding to the application program, and display a user interface corresponding to the display data on the display screen.
S202: it is determined whether there is a display engine in an idle state among the at least two display engines.
Here, the at least two display engines are display engines previously provided on a Printed Circuit Board (PCB). The number of the display engines on the PCB can be set according to the number of the display areas of the display screen and can also be set according to the actual requirements of users. The specific number of display engines is not limited herein.
Illustratively, if the number of the display areas of the display screen is four, the following are respectively: display area a, display area B, display area C and display area D, then, four display engines can be preset on the PCB, which are: the display engine A, the display engine B, the display engine C and the display engine D enable the display engine A to process the content to be displayed which needs to be displayed in the display area A, the display engine B to process the content to be displayed which needs to be displayed in the display area B, the display engine C to process the content to be displayed which needs to be displayed in the display area C, and the display engine D to process the content to be displayed which needs to be displayed in the display area D.
Furthermore, if the user needs to save space on the PCB, two display engines can be preset on the PCB, respectively: the display engine a and the display engine B, in this way, the display engine a can be made to process the contents to be displayed which need to be displayed on the display area a and the display area B, and the display engine B can be made to process the contents to be displayed which need to be displayed on the display area C and the display area D.
Next, a description will be given of how to determine whether there is a display engine in an idle state from among at least two display engines.
Specifically, the processor may obtain a return value of each display engine, and determine whether the display engine corresponding to the return value is in an idle state based on the return value. If the display engine corresponding to a certain return value is determined to be in an idle state, determining that the display engine in the idle state exists in at least two display engines; and if the display engines in the idle state are not determined after all the return values are detected, determining that the display engines in the idle state do not exist in at least two display engines.
Illustratively, the at least two display engines include: display engine a, display engine B, display engine C, and display engine D. The return value is '1', which indicates that the display engine corresponding to the return value is currently in a non-idle state; the return value is "0", which indicates that the display engine corresponding to the return value is currently in an idle state.
Specifically, the processor first obtains a return value of the display engine a, and determines that the display engine a is currently in a non-idle state if the return value is identified as "1"; and continuing to acquire the return value of the display engine B, and determining that the display engine B is in an idle state when the return value is identified to be 0. At this time, it is determined that one display engine B in an idle state exists, and it is determined that there is a display engine in an idle state, which is the display engine B, among the at least two display engines, and thus, it is not necessary to continue to determine whether the display engine C and the display engine D are in an idle state. The content to be displayed is directly sent to the display engine B, so that the time for the processor to determine the display engine C and the display engine D can be saved, and the display speed of the content to be displayed can be further improved.
Or the processor respectively obtains the return values of the display engine a, the display engine B, the display engine C and the display engine D, which are respectively: "1", "0", and "1", it is determined that the display engine B and the display engine C are currently in an idle state, and it is determined that there are display engines in an idle state, namely, the display engine B and the display engine C, among the at least two display engines. In this way, all display engines in the idle state in the current electronic device may be determined so as to determine the display engine most suitable for processing the content to be displayed, for example, the configuration of the display engine C is higher than that of the display engine B, and then, it is finally determined that the display engine C processes the content to be displayed.
Finally, if it is detected that the return values of the display engine a, the display engine B, the display engine C, and the display engine D are all "1", it is determined that there is no display engine in an idle state among the at least two display engines.
S203: if yes, determining a target display engine corresponding to the content to be displayed from the display engines in the idle state; and if not, determining a target display engine corresponding to the content to be displayed from at least two display engines.
First, how to determine a target display engine corresponding to content to be displayed from among display engines in an idle state is described.
Here, the display engine in the idle state includes the following two cases:
in the first case: there is only one display engine in the idle state.
Then the one display engine in the idle state is determined as the target display engine.
In the second case: there are at least two display engines in the idle state.
Here, the display engine in the idle state has the following two cases:
the first condition is as follows: and at least two display engines in the idle state do not have a display engine corresponding to the content type of the content to be displayed.
Then, one display engine may be arbitrarily determined from the at least two display engines as a target display engine, or one display engine may be determined from the at least two display engines as a target display engine according to a predetermined condition.
Specifically, the preset condition may be to determine the highest configured display engine as the target display engine. Therefore, the content to be displayed can be sent to the display engine which is in the best current configuration and is in the idle state for processing, and the display speed and the display effect of the content to be displayed can be further improved.
Case two: and the display engines corresponding to the content types of the contents to be displayed exist in the at least two display engines in the idle state.
Then, the target display engine is determined according to the pre-stored correspondence between the content type and the display engine. The step of determining the target display engine may specifically be:
the method comprises the following steps: based on the content to be displayed, a content type of the content to be displayed is determined.
Step two: and determining a display engine corresponding to the content type of the content to be displayed from at least two display engines in an idle state according to the corresponding relation between the content type and the display engine which is stored in advance.
Step three: and determining the display engine corresponding to the content type of the content to be displayed as a target display engine.
It should be noted that, because the correspondence between the content type and the display engine is to better correspond the display engine capable of processing the content to be displayed of a certain content type to the content type, according to the correspondence, a display engine most suitable for processing the content to be displayed can be determined for the content to be displayed, and the display effect of the content to be displayed is further improved.
For example, for the content a to be displayed, the processing effect of the display engine a on the content to be displayed of the content type, for example, the content a to be displayed, is good, and the processing effect of the display engine B on the content to be displayed of the content type, for example, the content a to be displayed, is general. In the above correspondence, what the content type of the content a to be displayed corresponds to is the display engine a. When at least two display engines in idle state are display engine A and display engine B, then according to the above-mentioned corresponding relation, the display engine A is determined as the target display engine of the content A to be displayed.
At this point, the target display engine corresponding to the content to be displayed is determined from the display engines in the idle state.
Next, how to determine a target display engine corresponding to content to be displayed from among at least two display engines will be described.
Here, since there is no display engine in an idle state in the electronic device, it is necessary to determine a target display engine corresponding to the content to be displayed among all display engines of the electronic device.
Specifically, the determining the target display engine may include the following steps:
the method comprises the following steps: based on the content to be displayed, a content type of the content to be displayed is determined.
Step two: and determining a display engine corresponding to the content type of the content to be displayed from at least two display engines according to the corresponding relation between the content type and the display engine which is stored in advance.
Step three: and determining the display engine corresponding to the content type of the content to be displayed as a target display engine.
It should be noted that the step of determining the target display engine is similar to the step of determining the target display engine in the second case, except that the step of determining the target display engine is performed from at least two display engines, and the step of determining the target display engine is performed from at least two display engines in an idle state in the second case. Therefore, for the specific implementation of the above steps, reference may be made to the steps in the second case, which is not described herein again.
Here, the determination of the content type of the content to be displayed in the first step needs to be described in detail:
in general, the content types may include: instant messaging type, video type, web page type, etc. The specific category of the content type is not limited herein.
It should be noted that the contents to be displayed that are not included in the above content types, or the contents to be displayed that have a low usage rate may be all classified into other types, so that all the contents to be displayed have corresponding display areas on the display screen, and the contents to be displayed do not need to be classified with too much effort.
Specifically, the content type of the content to be displayed may be determined according to a name (name) of the content to be displayed. The content type of the content to be displayed can also be determined according to the compression mode of the content to be displayed. Of course, the content type of the content to be displayed may also be determined according to other attributes of the content to be displayed. The specific content according to which the content type of the content to be displayed is determined is not limited herein.
Specifically, in order to quickly and accurately determine the content type of the content to be displayed, the first step may include:
step A: and extracting the application identifier of the application program generating the content to be displayed from the file name of the content to be displayed.
It should be noted that the file names of the contents to be displayed all have application identifiers of application programs corresponding to the contents to be displayed. For example: com, wherein the 'weixin' is an application identifier of the application program of the WeChat, and the extracted application identifier of the 'weixin' is the application identifier of the application program of the WeChat.
And B: based on the application identification, the application type to which the application program belongs is determined.
Here, the application type corresponding to the application identifier may be determined by a correspondence relationship between the application identifier and the application type. For example, the instant chat tools such as QQ and wechat are corresponding to the instant communication type, and the favorite and the love art are corresponding to the video type, and the content type is determined to be the instant communication type according to the application identifier of "weixin". The specific division form of the correspondence between the application identifier and the application type is not limited herein.
The corresponding relation can be stored in a memory of the electronic device, and when the processor needs to use the corresponding relation, the processor can immediately acquire the corresponding relation from the memory, so that the identification efficiency of the processor on the application identifier can be improved. The corresponding relation can also be stored in a storage medium outside the electronic device, and when the processor needs to use the corresponding relation, the processor acquires the corresponding relation from the storage medium outside the electronic device through a communication device in the electronic device, so that the corresponding relation can be prevented from occupying excessive memory of the storage of the electronic device.
And C: and determining the application type of the application program as the content type of the content to be displayed.
At this point, a target display engine corresponding to the content to be displayed is determined from the at least two display engines.
Finally, it should be noted that, if there is a display engine in an idle state in at least two display engines, a target display engine is first determined from the display engines in the idle state.
It should also be noted that the display engine refers to a device capable of displaying display data on a display screen. Specifically, the display engine may be a hardware synthesizer, such as a Graphics Processing Unit (GPU). The specific form of the display engine is not limited herein.
S204: and sending the content to be displayed to the target display engine so that the target display engine displays the content to be displayed in the target display area.
Specifically, the target display engine can display the content to be displayed in the target display area. The target display area is a display area corresponding to the content to be displayed in at least two display areas which are divided in advance of a display screen of the electronic equipment.
At this point, the content to be displayed is quickly displayed in the target display area of the display screen by the target display engine.
As can be seen from the above, in the split-screen display method provided in the embodiment of the present invention, after obtaining the content to be displayed, first, it is determined whether a display engine in an idle state exists in at least two display engines, then, if the display engine in the idle state exists, a target display engine corresponding to the content to be displayed is determined from the display engines in the idle state, if the display engine in the idle state does not exist, the target display engine corresponding to the content to be displayed is determined from the at least two display engines, and finally, the processor sends the content to be displayed to the target display engine, so that the target display engine displays the content to be displayed in the target display area. Therefore, the target display engine corresponding to the content to be displayed is determined from the plurality of display engines, so that the plurality of content to be displayed can be processed in different display engines, a large amount of content to be displayed is prevented from being processed by a certain display engine at the same time, the display speed of the content to be displayed can be increased, and meanwhile, the display error of the content to be displayed in the display screen can be avoided.
Based on the foregoing embodiment, in another embodiment of the present invention, in order to further improve the display effect of the content to be displayed on the display screen, if there is no display engine in the idle state in step S203, determining, from at least two display engines, a target display engine corresponding to the content to be displayed may include:
s2031: based on the content to be displayed, a content type of the content to be displayed is determined.
For the specific manner of determining the content type of the content to be displayed, reference may be made to the specific description related to the above step one, and therefore, the description is omitted here for brevity.
S2032: and determining a display engine corresponding to the content type of the content to be displayed from at least two display engines according to the corresponding relation between the content type and the display engine which is stored in advance.
Here, the correspondence relationship between the content type and the display engine may be set according to the characteristics of the display engine, for example, a display engine capable of efficiently processing a video type is associated with the video type; or may be set by the user in the electronic device, and is not particularly limited herein.
Illustratively, the electronic device includes two display engines, respectively: the display engine A and the display engine B, wherein the display engine A has a better processing effect on the display content of the video type, and in the corresponding relation, the display engine A is the display engine A corresponding to the video type. And when the content type of the content to be displayed is determined to be the video type, determining the display engine corresponding to the content to be displayed to be a display engine A according to the corresponding relation, determining the display engine A to be a target display engine, sending the content to be displayed to the display engine A for processing, and further improving the display effect of the content to be displayed in the display screen.
S2033: and determining the display engine corresponding to the content type of the content to be displayed as a target display engine.
Thus, a target display engine corresponding to the content to be displayed is determined.
It should be noted that, unlike the method for determining the target display engine in the foregoing embodiment, in this embodiment, it is not necessary to determine whether a display engine in an idle state exists in at least two display engines, but after obtaining the content to be displayed, the target display engine is determined from the at least two display engines according to the pre-stored correspondence between the content type and the display engine, and the content to be displayed is sent to the target display engine regardless of whether the target display engine is currently in an idle state. Because the target display engine has the best effect of processing the content to be displayed and the time for determining whether the display engine in the idle state exists in at least two display engines is avoided, the display effect of the content to be displayed can be improved, and simultaneously, the display speed of the content to be displayed can also be improved.
As can be seen from the above, in the embodiment of the present invention, a target display engine corresponding to the content type of the content to be displayed is determined according to the corresponding relationship between the content type and the display engine, and then the content to be displayed is sent to the target display engine, so that the target display engine displays the content to be displayed in the target display area, and the display effect of the content to be displayed in the display screen is further improved.
Based on the foregoing embodiment, in another embodiment of the present invention, in order to enable the target display engine to accurately display the content to be displayed in the target display area, step S204 may include:
s2041: and determining the area identification of the target display area corresponding to the content to be displayed according to a preset strategy.
The preset policy may be a correspondence between a display area and an area identifier, which are pre-stored in the electronic device.
Here, the area identifier is used to indicate a display area, and the area identifiers corresponding to different display areas are different so as to distinguish the different display areas.
Specifically, the region identifier may be a number, such as "1", "2", etc., or a letter, such as "a", "b", etc., or a symbol, such as "#", "", etc. The specific form of the region identifier is not limited herein.
For example, the corresponding relationship between the display area and the area identifier may be a table, where the table includes two rows and two columns, the first column stores the display area, the second column stores the area identifier, and each row stores a different display area and the area identifier of the display area.
Specifically, the processor determines the target display area, then finds the target display area from the corresponding relationship between the display area and the area identifier, and then determines the area identifier of the target display area from the second column of the same row, so that the area identifier of the target display area can be determined.
S2042: and sending the content to be displayed and the area identification of the target display area to a target display engine.
Here, sending the content to be displayed and the area identifier of the target display area to the target display engine may be sending the area identifier of the target display area to the target display engine first, and then sending the content to be displayed to the target display engine; or packaging the content to be displayed and the area identification of the target display area and then sending the packaged content and the area identification of the target display area to the target display engine; or adding the area identifier of the target display area into the content to be displayed, and then sending the content to be displayed with the area identifier of the target display area added to the content to be displayed to the target display engine. The specific transmission form for transmitting the content to be displayed and the area identifier of the target display area to the target display engine is not limited herein.
The content to be displayed and the area identifier of the target display area are sent to the target display engine, so that the target display engine displays the content to be displayed in the target display area of the display screen according to the area identifier of the target display area, and the accuracy of displaying the content to be displayed in the target display area can be improved.
As can be seen from the above, in the embodiment of the present invention, according to a preset policy, an area identifier of a target display area corresponding to a content to be displayed is determined; and sending the content to be displayed and the area identification of the target display area to a target display engine. Therefore, the target display engine can accurately display the content to be displayed in the display area according to the area identifier of the target display area by determining the area identifier of the target display area.
Based on the foregoing embodiment, in another embodiment of the present invention, when there is a display area not displaying the display content in the display screen, in order to improve the utilization rate of the display screen, step S2041 may specifically include:
s2041 a: it is determined whether there is an empty display area of the at least two display areas where no display content is displayed.
Here, it is determined whether there is an empty display area among the at least two display areas, and the return value of each display area may be detected by acquiring the return value of each display area to determine whether there is an empty display area among the at least two display areas. In this case, it is determined whether the display area is an empty display area by obtaining the return value of the display area in the prior art, and therefore details are not described herein.
S2041 b: if the display area exists, determining the area identifier of the empty display area according to the corresponding relation between the pre-stored display area and the area identifier; and determining the area identification of the empty display area as the area identification of the target display area.
Here, the blank display area mainly includes the following two cases:
in the first case: only one empty display area exists in the display screen.
Then, the empty display area is determined as a target display area, an area identifier of the target display area, namely the area identifier of the empty display area, is determined from the corresponding relationship between the display area and the area identifier, and the area identifier of the empty display area is further sent to a target display engine, so that the content to be displayed is displayed in the empty display area, and the utilization rate of the display screen can be improved.
In the second case: there are at least two empty display areas in the display screen.
The area identification of the target display area may then be determined in two ways:
the first method is as follows: and randomly determining one empty display area from the at least two empty display areas as a target display area, and determining the area identifier of the empty display area from the corresponding relation between the display area and the area identifier as the area identifier of the target display area.
Therefore, the next content to be displayed can be continuously displayed in other empty display areas, and the display screen can display more display contents at the same time.
