These drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the inventive concepts to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
Automobiles are moving towards intellectualization. A general phenomenon of intellectualization is an increase in the number of displays in automobiles that can provide entertainment and the like to a plurality of passengers in a vehicle. At present, a plurality of displays on an automobile can respectively provide services for a plurality of passengers, and the method is specifically realized by the following steps:
FIG. 1A is a schematic diagram of a prior art control logic. As shown in fig. 1A, the control logic includes: a plurality of electronic control units, a plurality of drive circuits, and a plurality of displays.
The electronic control units comprise N electronic control units, N is a positive integer larger than 0, and the N electronic control units are respectively marked as an electronic control unit 1, an electronic control unit 2 and an electronic control unit … …. Aiming at one electronic control unit, also called as a driving computer, which is one of the core elements of automobile electronics, a plurality of electronic control units in an automobile are possible, each electronic control unit corresponds to different automobile control functions, and the electronic control units can interact with each other to realize diversified services.
The plurality of driver circuits includes N driver circuits, which are denoted as driver circuit 1, driver circuit 2, and … … driver circuit N, respectively.
The plurality of displays includes N displays, denoted as display 1, display 2, … … display N, respectively.
One electronic control unit in the plurality of electronic control units is sequentially connected with one driving circuit and one display, and one electronic control unit can drive one display to display through one driving circuit.
Any two electronic control units in the plurality of electronic control units are connected with each other.
The following takes the electronic control unit 1, the driving circuit 1, and the display 1 as an example to describe in detail how the electronic control unit 1 controls the display 1 to display corresponding contents, and shares the display contents of the display 1 with other displays:
in some examples, an application icon is displayed on the display 1, a user may initiate a resource obtaining request to the electronic control unit 1 by clicking the application icon, and the electronic control unit 1 obtains a corresponding resource according to the resource obtaining request and drives the display 1 to display the resource through the driving circuit 1.
If a user needs to share the display content of the application a on the display 1 with the display 2 and the display 3, the electronic control unit 1 needs to copy the display content of the application a twice, and respectively send the copy to the electronic control unit 2 and the electronic control unit 3, then the electronic control unit 2 controls the driving circuit 2 to drive the display content of the application a to the display 2 for displaying, and the electronic control unit 3 controls the driving circuit 3 to drive the display content of the application a to the display 3 for displaying, so that screen sharing between the display 1 and the display 2 and between the display 3 and the display 2 is realized.
Taking the example of sharing the display content of the application a on the display 1 to the display 2, as shown by a dotted arrow in fig. 1, the transmission link of the display content of the application a is composed of the electronic control unit 1, the electronic control unit 2, the driving circuit 2, and the display 2. It can be seen that the transmission link of the display content of the application a is long, and the electronic control unit 1 and the electronic control unit 2 both need to process and output the display content through software, which may result in a long time consumption in the screen sharing process, and may cause a long delay and poor user experience in the display content of the application a on the display 2 compared to the display 1.
In addition, if an operation on the application a occurs on the display 2, another operation on the application a occurs on the display 1, and the processing logic of the application a is processed in the electronic processing unit 1, the processing logic should be, for each user operation time: responding to the operation on the display 2 and then responding to the operation of the display 1.
However, if the operation on the display 1 and the operation on the display 2 are temporally close to each other, the operations are transmitted to the electronic control unit 1 according to the above-described link, and the electronic control unit 1 receives the operation on the display 1 first and then receives the operation on the display 2. The display 1 operation is responded to first and then the display 2 operation, resulting in confusion of the display processing logic.
FIG. 1B is a schematic diagram illustrating a multi-screen display control logic according to the prior art. As shown in fig. 1B, the application a on the display 1 is an application of the electronic control unit 1. Assume that application a is displayed in full screen on display 1 with full screen display coordinates (w 1, h 1), but after application a shares on display 2, it is displayed in a small area on display 2 with coordinates { X2, Y2, w2, h2} on display 2.
If the operation point P on the display 1 is (x 1a, y1 a), the application A receives the P point operation, which is equivalent to (x 1a, y1 a) of the application A; the absolute coordinates P2 of the operation point of the display 2 are (x 2a, y2 a); if the absolute coordinates of P2 are sent to the electronic control unit 2, the electronic control unit 2 sends the absolute coordinates of P2 to the electronic control unit 1. The electronic unit control 1 may misunderstand that the operation coordinates of the application a are (x 2a, y2 a), and respond according to (x 2a, y2 a), resulting in a response error.
In view of the above technical problems, the inventors of the present application propose the following technical idea: aiming at N displays, N display lines are arranged in a screen driving circuit, each of the N display lines corresponds to one display and is used for sending display contents required by the display corresponding to the display line to the display; in addition, a plurality of sharing lines, e.g. C, are provided in the screen driving circuit N The display device comprises N-1 sharing lines, wherein each sharing line in the plurality of sharing lines is used for sharing display content on one display to the other display, each display in the N displays corresponds to the N-1 sharing lines, and each display can share own display content to the other N-1 displays. And then according to the screen sharing sending end and the screen sharing receiving end, a target sharing line for sharing the display content of the screen sharing sending end to the screen sharing receiving end is determined, and the display content of the screen sharing sending end is shared to the screen sharing receiving end through the target sharing line, so that screen sharing is achieved.
