In a specific example, in the prior art solution of the smart terminal, each physical screen usually has a proprietary framebuff for drawing the content to be displayed, as shown in fig. 1a, the content between multiple screens has no logical association from the display perspective, and each screen displays its own independent content. If the display content between a plurality of screens is expected to generate logic correlation, the contents of the framebuff of each screen need to be pieced together, and meanwhile, the synchronization of the frames is considered, so that the correlation effect of the displayed contents is generated. The piecing up of the display data stored in the individual framebuffs corresponding to each screen is very complicated, not only time-consuming, but also error-prone, so the embodiment of the present invention proposes a display method, as shown in fig. 1b, creating a super virtual screen framebuff (which may also be a super display view) that includes all screen regions, and drawing the framebuff content of the super virtual screen that spans a single physical screen in the data of the display content of the virtual screen, for example, a whole picture, or displaying a video that a flying bird flies from right to left. Then, the contents of the framebuff of the super virtual screen are cut and cut according to actual needs, and are overlapped with the framebuff display content data of a specific physical screen, so that the contents are displayed on each specific physical screen.
In another specific example, as shown in fig. 1c, the virtual screen includes a large complete image, and the content of the image is cut and displayed on each small physical screen according to the physical size and position of the physical screen to be displayed, so that the display content of each screen has a logical relationship, that is, the content displayed on each screen is a part of the whole image, for example, the screen at the upper left corner displays the upper left part of the whole image, and the screen at the right corner displays the right part of the whole image. All the contents displayed by the physical display screens are combined to form a complete image.
The embodiment of the invention provides a concept of a super virtual screen containing all physical screen display contents; the method has the advantages that the content of the super virtual screen is cut, so that a part of the whole logic display content is presented for a single physical screen, and the implementation mode of the logic relevance of the display contents of a plurality of screens is simplified.
