Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
First, some terms or terms appearing in the description of the embodiments of the present application are applicable to the following explanations:
a signal source: a video signal source, such as a DVI signal output of a video card, a PC desktop signal, etc.;
displaying the object: according to an example generated by grouping the data to be displayed, the example is called an information piece in the embodiment of the application, and is an abstract object of a software layer, and logically represents a piece of data information.
The transparency property: for representing the opacity level of a display object, e.g. the accessibility property of a browser.
And the spliced screens are used for splicing and displaying the same item (or data) to be displayed by a plurality of independent display screens.
Example 1
In the process of displaying the spliced screen, in the related art, the adopted technical means is generally a screen display scheme based on an independent signal source, for example, each display screen forming the spliced screen corresponds to an independent PC, and when contents are displayed, the contents of each display screen are only displayed in the respective display screen, so that when a display object is displayed in a fusion manner, only some information can be covered on other information, and the covered information cannot be displayed in a semi-transparent manner. In view of the above problems, embodiments of the present application provide a corresponding solution.
Specifically, in the process of displaying the tiled screen, a layer of software solution is introduced in the embodiment of the present application on the basis of the original hardware, as shown in fig. 2, in the embodiment of the present application, the display interface of the complete tiled screen is regarded as an oversized rectangular desktop, and a plurality of cards with different contents, that is, the aforementioned information sheets, are placed on the display interface, and are replaced by the information sheets in the figure for convenience of description. The information pieces can be placed at any position of the display interface, and the positions of the information pieces can be mutually overlapped. Each piece of information, still developed in web technology, corresponds to a DOM node in the web page. Then a tiled screen presentation becomes the development of many sheets of information, as well as the assembly and grouping of sheet layouts. The signal fusion problem in the traditional splicing screen scheme is solved and becomes the fusion problem of the information pieces. Because the information piece is a dot on the implementation level, and the fusion of the dot can be realized by setting the css accessibility attribute.
Therefore, one spliced screen display project becomes development of a plurality of information pieces and splicing and combining of information piece layouts. The information sheet only focuses on the data information which needs to be displayed, the existence and the limitation of a physical screen are not needed to be concerned, and the position occupied by the information sheet can be any area in the display interface of the splicing screen.
Based on the above ideas, an embodiment of the present application provides a data display system of a tiled screen, as shown in fig. 3, including: control device 30, server 32 and tiled screen 34 to enable the association of tiled screen display interface, information pieces with the actual physical screen (signal source). Optionally, the display system may be built based on node. Wherein:
a control device 30 for sending a control instruction to the server; alternatively, the control device 30 may be a mobile phone, a tablet computer, a PC, etc., but is not limited thereto. The control instruction may be generated according to an operation of a user, for example, when the control device is a mobile phone or a tablet computer, the operation of the user (which may be a touch operation or a physical key operation) is detected; when the specified operation is detected, the control instruction is generated and sent to the server. In an alternative embodiment, the control device 30 may send an instruction to the server to open or close a certain information piece, and the server may update the status of the information piece and broadcast it to all the display ends of the mosaic screen (i.e. the mosaic screen).
The server 32 mainly manages the class 2 objects, the screen and the information pieces, and the connection conditions of all spliced screens, and specifically comprises the steps of managing some resource files and serving as webserver to provide resource services to the outside; creating and deleting information piece instances, and managing the position information of all information pieces in the abstract desktop; connection of all display terminals (i.e., display screens, such as the display in fig. 3); critical information, such as the case of information pieces and display screens (screens), is broadcast to interested parties (e.g., the corresponding tiled screen) in real time.
It can be seen that the server is only responsible for managing the information pieces (i.e. the display objects) and the spliced screen, but the control of the transparency property of the information pieces in particular also needs a controller to implement, and in particular, the server 32 receives the above control instruction from the control device; adjusting the transparency attribute of each display object in the current display interface of the spliced screen according to the control instruction, wherein the display objects are grouped and generated examples according to the data to be displayed; sending notification information for indicating an adjustment result to the splicing screen;
a mosaic screen 34, as a final display side, formed by mosaic of a plurality of display screens, for receiving the above-mentioned notification information from the server; and adjusting the transparency attribute of each display object in the display interface according to the notification information. When the mosaic screen 34 interacts with the server, a large desktop system is formed by splicing matrixes abstracted as [ MxN ], each point in the matrixes represents a physical display screen (screen), and the resolutions of all the display screens (screen) are the same, such as 1400x 1050. The property specific to each display (screen) is its position (x, y) in the matrix, e.g. the position of the display (screen) in display0 is (0,0) and the position of the display6 is (1, 2). Each screen runs a full-screen chrome browser, and the accessed address is the content display provided by the server. The server can be informed by means of the id parameter which block screen it represents.
Based on the desktop system, in the mosaic screen (i.e. the mosaic screen display), each screen downloads the class definition file (js file) related to all the running information pieces, and generates an information piece instance in the current running environment. Each piece of information instance actually corresponds to one dom node, so that the piece of information instance is actually hung on the corresponding dom after being generated, and the final visual presentation is realized. The definition file of the information piece is essentially a definition of a reacbjs component, which can be conveniently mount to a dom. Each screen has its id, for example, the screen with id (i, j) will offset all the pieces of information in the container, and the implementation means is to translate (offset x, offset y) the container dom of the pieces of information, where offset x is (1400 i + app.x) and offset y is (1050 j + app.y), where app.x and app.y represent the display positions defined by the pieces of information on the server side. The attribute of the information piece is the transparency (alpha attribute), and the accessibility value of the corresponding dom is set according to the value of the attribute.
Based on the above design concept, the following describes in detail the interaction process between the display screen and the server in the tiled screen with reference to fig. 4, as shown in fig. 4, including the following processing steps:
step S402, the spliced screen is connected with a server (server) through websocket, and the server is informed that the current display screen is the display screen marked as screen (0, 0);
step S404, the server returns the currently opened information piece condition and some global information;
step S406, screen (0,0) requests to download js resource files related to the opened information pieces;
step S408, the server returns the js resource file of the information piece;
in step S410, screen (0,0) generates an instance (instance) of an information piece according to the class (class) definition of the information piece, and places the instance at a corresponding location.
To sum up, this embodiment provides a brand-new solution of preparation concatenation screen, compares traditional scheme and has solved the unable problem of crossing the screen of show information, abstracts the concatenation screen as the desktop container, and the information is abstracted as the information piece in the container, and the combination that the demonstration of concatenation screen is abstracted to, and the container is responsible for good overall arrangement, has solved the show information problem of crossing the screen from this.
