[0051] The present specification can use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which can refer to one or more of the same or different embodiments of the application.

[0052] Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0053] As Figure 1 shown, the embodiments of the present application provide a display control method, comprising:

[0054] S100: creating a virtual display screen, the virtual display screen being used to acquire content to be displayed;

[0055] S200: determining a display parameter of a display used for displaying the to-be-displayed content;

[0056] S300: processing the to-be-displayed content obtained by the virtual display screen according to at least the display parameter, to form at least content capable of being displayed by the display;

[0057] S400: controlling the display to display the processed to-be-displayed content.

[0058] For example, the electronic device has a physical display screen, hereinafter referred to as a display screen, in order to avoid the phenomenon that the user cannot process the to-be-displayed content before it is displayed by the display screen, the operating system such as the windows system directly delivers the to-be-displayed content processed by the graphic card to the display screen for display based on the previous operation. In the embodiment, a virtual display screen is first created, and the virtual display screen is controlled to receive the to-be-displayed content output by the graphic card instead of the physical display screen, that is, the virtual display screen is used to obtain the to-be-displayed content, so as to avoid that the to-be-displayed content is directly delivered to the display screen by the graphic card. Then, a display parameter of the display screen used for displaying the to-be-displayed content is determined, the display parameter can reflect the display characteristics of the display screen, such as the content attribute and the display effect that can be supported by the display screen. According to the display parameter, the processing algorithm can perform matching processing on the to-be-displayed content, so that the processed to-be-displayed content is matched with the display parameter, and it is ensured that the display screen can display the to-be-displayed content based on the display characteristics. Moreover, the processing algorithm can also receive a user inputted custom display instruction, the instruction also contains the display parameter which is partially the same as the display parameter of the display screen, so as to ensure that the display screen can display the processed to-be-displayed content, and the display parameter in the instruction can also contain the corresponding parameter of the display effect supported by the display screen, so that the processed to-be-displayed content can achieve the display effect expected by the user after being displayed by the display screen. Alternatively, the processing algorithm can also automatically determine the display effect matched with the to-be-displayed data according to the previous historical data, experience data, etc., and then process the to-be-displayed data combined with the display parameter of the display screen, to obtain the to-be-displayed content which can be matched and displayed by the display screen and has the target display effect. When the processing of the to-be-displayed content is completed, the to-be-displayed content can be controlled to be transmitted to the display screen for display.

[0059] Based on the disclosure of the above embodiments, the beneficial effects of the present embodiment include creating a virtual display screen for obtaining the content to be displayed, and causing the virtual display screen to determine the display parameters of the display for displaying the content to be displayed, and then processing the content to be displayed based on the display parameters to form content that can be displayed by the display, and controlling the display to display the processed content to be displayed. Based on the method of the present embodiment, the display control is no longer controlled by the operating system, so the display content can be changed according to the actual situation, such as different types of display screens, or user's custom needs, to improve the display function and effect, and make the display diversified.

[0060] Specifically, the virtual display screen is created, and the virtual display screen obtains the content to be displayed, including:

[0061] The virtual display screen is created, and the configuration parameters of the display of the electronic device are modified to make the display output control of the display by the electronic device or the operating system be handed over to the processing algorithm, and then the virtual display screen obtains the content to be displayed based on the processing algorithm.

[0062] For example, as shown in Figure 2 A virtual display screen can be created based on an application program or a software operation interface, such as an IDDCX interface, then the EDID (Extended Display Identification Data) in the registry of the electronic device can be modified, and then the display can be initialized through the winrt underlying interface, and then the display can be shielded so that the operating system cannot identify the display, and finally the display is no longer managed by the display framework of the operating system. Then, the modified EDID can be reported to the operating system, so that the operating system can regard the virtual display screen as a display. At this time, the content to be displayed controlled by the operating system is processed by the video card and then obtained by the virtual display screen, so that the processing algorithm can perform subsequent post-processing on the content to be displayed, and then the processed content to be displayed is transmitted to the display for display.

[0063] Further, the virtual display screen in the present embodiment can obtain the content to be displayed based on the DirectX interface (an application program interface), which has the function of accessing the video card and the sound card, so as to realize the effect that the virtual display screen obtains the content to be displayed output by the video card, such as mapping the content to be displayed output by the video card to the virtual display screen, so that the virtual display screen obtains the content to be displayed. Of course, the above-mentioned method for realizing that the virtual display screen obtains the content to be displayed is not unique, and is not limited to using the DirectX interface.

[0064] Further, when the virtual display screen obtains the content to be displayed according to the display parameters, the present embodiment includes:

[0065] S301: copying the content to be displayed of the virtual display screen to a memory buffer, and performing image processing on the content to be displayed in the memory buffer.

[0066] For example, the content to be displayed obtained by the virtual display screen, including the graphical interface of an application program, is first copied to a memory buffer, such as a display buffer memory of a Gpu, and then the content to be displayed in the memory buffer is processed based on a processing algorithm in combination with display parameters. In this embodiment, the copying of the content to be displayed is also implemented by a DirectX interface, and can also be implemented based on other program interfaces.

[0067] Further, as shown in Figure 3 When the electronic device is connected with multiple different displays, the content to be displayed is processed based on at least the display parameters, including:

[0068] S302: determining the type of the content to be displayed;

[0069] S303: determining a target display for displaying the content to be displayed based on the type of the content to be displayed and the display parameters of each display;

[0070] S304: processing the content to be displayed based on the display parameters of the target display;

[0071] The display parameters at least include one or more of the following: color, resolution.

[0072] For example, the type of the content to be displayed can be determined first, such as whether the content to be displayed is a document or a multimedia, and then the target display most suitable for displaying the content to be displayed can be determined based on the type of the content to be displayed and the display parameters of each display that have been determined, and the target display can also be determined based on the running state of the current multiple displays, such as which displays are in an idle state. Since the display parameters of a display can represent the display characteristics of the display, based on the characteristics, it can be determined which type of content to be displayed is more suitable for the display or can only be displayed, and based on this algorithm, the target display for matching the content to be displayed can be determined, and when the target display is determined, the algorithm can further refine the content to be displayed based on the display parameters of the target display, or further refine the content to be displayed in combination with the display requirements input by the user, so that the target display can perfectly present the preset effect when displaying the processed content to be displayed.

[0073] For example, in the application, the algorithm first determines that the display type of the to-be-displayed content is multimedia, which can be a video stream in particular. In order to ensure that the video stream can be displayed clearly, a high-resolution display is preferably selected for display. Therefore, based on this, the algorithm filters the display parameters of multiple displays to determine that the display that supports displaying the video stream and is high-resolution is the target display. At this time, the algorithm can process the video stream based on the display parameters of the target display, such as processing the resolution of the video stream to form a high-resolution video stream, so that the display effect is best when displayed by the target display.

[0074] Alternatively, the algorithm first determines that the display type of the to-be-displayed content is a document, which can be a PPT or TXT document in particular. When it is a PPT document and a color document, such as a PPT containing pictures, the algorithm can determine that this type of document also needs high resolution and high definition display based on the document type, that is, the algorithm determines the best display effect of the to-be-displayed content and the display parameter range required to achieve the effect. Then, the algorithm can filter the display parameters of multiple displays based on the determined information to ultimately determine the matching target display. When the document type is a TXT document, it is black and white and the character spacing is small. At this time, in order to facilitate user reading, the algorithm can determine to use a screen with black and white as the keynote or a screen with a small display area for display, which is the best effect and easy for users to read. Therefore, the algorithm can filter the display parameters of multiple displays based on the determined information to ultimately determine that the display with a slightly smaller display area and a black and white keynote is the target display, such as determining a display with an ink screen as the target display.

[0075] In addition, if the type of the to-be-displayed content or the display requirement input by the user represents that the display content supports or needs to be displayed with a special effect, the algorithm can also filter the display parameters of multiple displays based on the special effect or in combination with the display requirement input by the user to ultimately determine that the special display effect of the to-be-displayed content can be achieved in a better way.

[0076] Further, in the embodiment, when determining the type of the to-be-displayed content, the following is included:

[0077] S305: determining an application program that generates the to-be-displayed content;

[0078] S306: determining the type of the to-be-displayed content based on the application program; or

[0079] S307: determining the type based on the format of the to-be-displayed content.

[0080] For example, if the to-be-displayed content is generated by a video player, an animation making program, a 3D image processor or the like, the algorithm can determine the type of the to-be-displayed content based on the source of the to-be-displayed content, i.e., the application program that generates the content. For example, the to-be-displayed content generated by a video player, an animation making program or the like is usually of a video type, the to-be-displayed content generated by a 3D image processor or the like is of a picture type, and the to-be-displayed content generated by a WORD program or the like is of a document type. Alternatively, the name of the to-be-displayed content has a suffix representing the format thereof, or the attribute information of the to-be-displayed content contains format information, etc. In this case, the algorithm can accurately determine the type of the to-be-displayed content based on the format information.

[0081] Further, in another embodiment, when the display includes multiple displays, the to-be-displayed content is processed according to at least the display parameter, including:

[0082] S308: determining a target display for displaying the to-be-displayed content based on a user instruction;

[0083] S309: processing the to-be-displayed content based on the display parameter of the target display;

[0084] The display parameter includes at least one or more of the following: color, resolution.

[0085] For example, the user instruction is obtained, which contains information of a target display specified by the user for displaying the to-be-displayed content. Based on the information, the algorithm can directly determine the display that needs to display the to-be-displayed content. Then, the algorithm can directly determine the display parameters of the target display and directly process the to-be-displayed content based on the display parameters to form a form that can be displayed by the target display. The display parameters in the embodiment include, but are not limited to, corresponding parameters such as color, resolution, display effect / feature, etc. The color parameters include color, saturation, contrast, brightness, etc. When processing, the color of the to-be-displayed content can be adjusted, such as being adjusted to black and white tone, cold tone, warm tone, etc. The saturation, contrast, and brightness of the to-be-displayed content can also be adjusted to make the display effect different. Low-resolution images can also be super-resolution processed to form high-resolution images, etc. The specific adjustment needs to be matched according to the specific display parameters. The to-be-displayed content can also be adjusted according to the user input instruction about the display effect and display requirement. For example, when the input instruction contains information for displaying the to-be-displayed content in a certain special effect, the algorithm can further adjust the to-be-displayed content based on the display information of the special effect, so that the target display can display the processed to-be-displayed content in the special effect indicated by the user when displaying the to-be-displayed content. The special effect can be thermal imaging effect display, different tone display, etc. For the to-be-displayed content containing audio, such as audio-video, the output of the audio can also be adjusted when applied, so that the overall output effect of the to-be-displayed content meets the special effect required by the user.

[0086] Specifically, when the display is an ink screen,

[0087] Processing the to-be-displayed content based on at least the display parameters of the display, including:

[0088] S310: When the to-be-displayed content is a first image, processing the first image based on the display parameters of the display to form a second image that can be displayed by the display. The first image and the second image are different at least in color.

[0089] For example, when the display is an ink screen, the display parameters at least have a requirement that the color of the to-be-displayed content needs to be black and white tone. Therefore, when the to-be-displayed content is a first image and is a color image or other non-black and white tone image, or the to-be-displayed content is a video stream formed by a plurality of first images, the processing algorithm will at least change the color of the first image to black and white to form a black and white image or a video stream with black and white tone. Of course, not only the tone will be changed. If the resolution, saturation, etc. of the display do not match the parameter information in the attribute information of the current to-be-displayed image, corresponding changes also need to be made so that the display can normally display the to-be-displayed content.

[0090] When the display is a high-resolution display

[0091] processing the to-be-displayed content based on the display parameter of the display, comprising:

[0092] S311: when the to-be-displayed content is a low-resolution image, processing the low-resolution image based on the display parameter of the display to form a high-resolution image adapted to the display.

[0093] For another example, the display is a high-resolution display, when the algorithm determines that the to-be-displayed content is a low-resolution image or a video stream formed by a low-resolution image through the identification analysis, the algorithm can perform super-resolution processing on the to-be-displayed content based on the parameter related to the resolution in the display, so as to form a high-resolution image or a video stream matched with the display parameter, and then enable the display to normally display the to-be-displayed image. Also, similarly, the resolution adjustment is only one of them, if the display parameter is inconsistent with other parameters related to color, corresponding adjustment is also needed. In addition, if the user inputs a special requirement related to the display effect, such as a requirement of displaying a special effect, the algorithm also needs to further adjust the to-be-displayed content in combination with the parameter related to the display effect input by the user.

[0094] Optionally, the algorithm can also determine the current ambient light intensity or determine the current time period, and then determine the display effect adapted to the current environment based on the ambient light intensity and / or the time period, and then assist in adjusting the display parameter of the to-be-displayed content in combination with the determined display effect, so that it not only meets the display requirements of the display and the display requirements customized by the user, but also meets the display requirements of the current environment.

[0095] Optionally, when the display is multiple, the processing algorithm can also control different displays to display different contents, which can be specifically implemented in combination with different modes of the virtual display screen, for example, when the virtual display screen runs a copy mode, the to-be-displayed content can be processed and then copied and mapped to a certain display, so that it is synchronously displayed with the virtual display screen itself, or the virtual display screen runs an expansion mode, based on which the virtual display screen can send the processed to-be-displayed content to different displays, so that the contents displayed by each display are different from the virtual display screen, or the contents displayed by each display are all different. For example, the first display can display the to-be-displayed content without processing, the second display can display the to-be-displayed content in black and white color, the third display can display the to-be-displayed content in high resolution, and the fourth display can display the to-be-displayed content with special display effect.

[0096] Further, when controlling the display to display the processed to-be-displayed content, it comprises:

[0097] S401: controlling to render the processed to-be-displayed content to the display.

[0098] Specifically, in the embodiment, the processed to-be-displayed content can be first copied to a memory buffer based on a DirectX interface (or other plug-in), the to-be-displayed content in the memory buffer is processed based on display parameters, then a rendering pipeline can be created based on the DirectX interface (or other plug-in), and the processed to-be-displayed content is rendered and drawn to a target display based on the rendering pipeline, so as to realize display.

[0101] a determining module configured to determine display parameters of a display configured to display the to-be-displayed content;

Based on the electronic device of the embodiment, the display control right of the electronic device is no longer controlled by the operating system, so the display content can be changed according to actual conditions, such as different types of display screens or user-defined requirements, so as to improve display function and effect and make display diversified.
