In order to describe in detail the possible application scenarios, technical principles, specific solutions that can be implemented, goals and effects that can be achieved, etc., the following will be described in detail in conjunction with the listed specific embodiments and accompanying drawings. The embodiments described herein are only used to illustrate the technical solutions of the present application more clearly, so they are only examples, and cannot be used to limit the protection scope of the present application.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The word "embodiment" appearing in various positions in the specification does not necessarily refer to the same embodiment, nor does it specifically limit its independence or relationship with other embodiments. In principle, in this application, as long as there is no technical contradiction or conflict, each technical feature mentioned in each embodiment can be combined in any way to form a corresponding implementable technical solution.

Unless otherwise defined, the meanings of the technical terms used herein are the same as those commonly understood by those skilled in the art to which the application belongs; the use of relevant terms herein is only to describe specific embodiments, and is not intended to limit the application .

In the description of this application, the term "and/or" is an expression used to describe the logical relationship between objects, indicating that there may be three relationships, such as A and/or B, which means: there is A, there is B, and There are three situations A and B at the same time. In addition, the character "/" in this article generally indicates that the contextual objects are a logical relationship of "or".

In this application, terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is a relationship between these entities or operations. Any actual quantitative, primary or sequential relationship.

Without further limitation, in this application, the words "including", "comprising", "having" or other similar expressions are intended to cover a non-exclusive inclusion, and these expressions do not exclude Additional elements may also be present in a process, method, or product that includes the stated elements, so that a process, method, or product that includes a series of elements may include not only those defined elements, but also other elements that are not explicitly listed , or also include elements inherent in such a process, method, or product.

In the present application, expressions such as "greater than", "less than", and "exceeding" are understood as excluding the original number; expressions such as "above", "below", and "within" are understood as including the original number. In addition, in the description of the embodiments of the present application, "multiple" means more than two (including two), and similar expressions related to "many" are also understood in this way, such as "multiple groups", " many times", etc., unless otherwise expressly and specifically defined.

For the multi-screen different display application in the existing technical solutions, during use, each physical display can only display one picture of the different display application at a time, which will greatly limit the application of multi-screen different display in many scenarios. For example, in a high-end vehicle multimedia scene, the high-end vehicle multimedia is often equipped with a surround-view panoramic image. If a physical display can only display a picture of a different display application at a time, six physical displays need to be equipped on the vehicle to achieve a panoramic view. image. Or in the KTV audio-visual scene, if you want to realize multi-person interaction in KTV, you need to equip a number of physical monitors equivalent to the number of people, and the multi-person images cannot be displayed on the same screen. These have greatly limited the application of multi-screen different display, and caused great obstacles to the use of multi-screen different display by users.

In addition, if you want to simultaneously display multiple images of different display applications on one physical display at the same time, you can modify the application side. However, it will cost a lot of development cost to modify the application side, and the implementation period is long. At the same time, after the application side is modified, when the scene is changed and the application side is different, the method will no longer be applicable, which greatly limits the promotion of the method. For example, when the high-end in-vehicle multimedia application side modifies its own application in order to simultaneously display multiple images of different display applications at the same time, the KTV audio and video scene cannot apply to the modified application to simultaneously display multiple different display applications at the same time. screen.

In order to at least solve the above problems, the present disclosure provides a multi-screen different display solution. According to an embodiment of the present disclosure, device information of a physical display is acquired, and multiple logical displays are set according to the device information of the physical display. A plurality of logical display rendering pictures respectively corresponding to the plurality of logical displays are obtained, and the plurality of logical display rendering pictures are spliced to obtain a different display picture. In addition, the different display picture is submitted to the physical display, so that the physical display performs multi-screen different display according to the different display picture. In this way, multiple screens with different displays can be realized through the simple configuration above without modifying the application side.

In this application, the system side is modified, a physical display is divided into multiple virtual screens, and each virtual screen is independently registered as a logical display. In this way, while breaking through the limitation that a physical display can only display one different display application screen at the same time, there is no need to modify the application side, reducing development costs and development cycles, and improving the applicability of the method. According to an embodiment of the present disclosure, the above multi-screen different display solution is implemented by configuring the system end, which may be a corresponding module of the operating system.
