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, which can be derived by a person skilled in the art from the embodiments given herein 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 accompanying drawings 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. Furthermore, 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.;
and 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 the information piece is an abstract object in a software layer and logically represents a piece of data information.
And display attributes: the properties of the display object may include, for example, but are not limited to, the display state (display on or display off), the size of the display area, the display position, the format of the display content, and the like.
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 the display of 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, when content is displayed, the content of each display screen is only displayed in the respective display screen, and cannot be displayed across the display screens, and in addition, due to the display of the resolution of the signal source, high-resolution information cannot be displayed when large-screen display is performed. 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. 2a, in the embodiment of the present application, the display interface of the complete tiled screen is regarded as an oversized rectangular desktop, and a lot of cards with different contents, that is, the aforementioned information sheets, are placed on the desktop, and are replaced by the information sheets in the drawings for convenience of description. The information piece can be placed at any position of the large desktop, and the size of the information piece can be expanded within the range allowed by the desktop. Fig. 2b illustrates the principle of the large screen display effect, as shown in fig. 2b, each display screen (screen1 and screen2) generates information pieces 1-3, and because the display interface of each display screen is limited, the information pieces displayed by the display screens are displayed in a combined manner, so that the uppermost display effect in fig. 2b is obtained.
Therefore, a large-screen display project becomes the development of a plurality of information sheets and the assembly and combination of the information sheet layout. 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 concerned, and the position occupied by the information sheet can be any area in a large-screen display interface.
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 association of large screen display interfaces, pieces of information with the actual physical screen (source). Optionally, the display system may be built based on nodejs and websocket, for example, but not limited to, a B/S system may be built. 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 a command to the server to open or close a certain information piece, and the server updates the status of the information piece and broadcasts it to all large-screen display terminals (i.e. the spliced 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 the information pieces in an abstract display interface; the connection condition of all display ends (namely display screens); critical information such as the information pieces and screen (i.e. display screen) conditions are broadcast to interested parties (e.g. the corresponding mosaic 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 display properties of the information pieces specifically needs a controller to implement, specifically, the server 32 receives the above control instruction from the control device; adjusting the display attribute of each display object in the current display interface of the spliced screen according to the control instruction, wherein the display object is an example generated by grouping 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 display attribute of each display object in the display interface according to the notification information. Optionally, the tiled screen 34 can be modified as follows:
a desktop system is formed by splicing matrixes with large screens abstracted to [ MxN ], each point in the matrixes represents one physical screen (screen), and the resolutions of all display screens (screens) are the same, such as 1400x 1050. The property specific to each screen is its position (x, y) in the matrix, such as the position of the screen of display0 is (0,0) and the position of the screen of display6 is (1, 2). Running in each screen is a full-screen chrome browser, and the accessed address is content display provided by the server. The server itself can be informed which block screen it represents by the id parameter.
Based on the desktop system, in the spliced screen (i.e. the large screen display), each screen downloads class definition files (js files) related to all running information pieces, and generates an information piece instance in the current running environment. Each information piece instance actually corresponds to one dom node, so that the information piece 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.
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 screen is screen (0, 0);
step S404, the server returns the information piece condition opened currently 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 a js resource file of the information piece;
in step S410, screen (0,0) generates a piece instance according to the class definition of the piece, and places the piece instance at the corresponding position.
In summary, the present embodiment provides a brand-new solution for making a large screen, and compared with the conventional solution, the problem that the displayed information cannot cross the screen is solved, the large screen is abstracted as a desktop container, the information is abstracted as information pieces in the container, the display of the large screen is abstracted as a combination of the information pieces, and the container is responsible for the layout of the information pieces, so that the problem that the displayed information crosses the screen is solved.

Further, the data processing circuit may be a single stand-alone processing module, or incorporated in whole or in part into any of the other elements in the computer terminal 50 (or mobile device). As referred to in the embodiments of the application, the data processing circuit acts as a processor control (e.g. selection of a variable resistance termination path connected to the interface).

Under the operating environment, the application provides a data display method of the spliced screen as shown in fig. 5. Fig. 6 is a flowchart of an alternative data display method for a tiled screen according to an embodiment of the present application. As shown in fig. 6, the method includes steps S602-S604, in which:
step S602, receiving notification information from a server, wherein the notification information is used for notifying a mosaic screen to update the display attributes of each display object in the current display interface of the mosaic screen, and the notification information is sent by the server after the server adjusts the display attributes of the display objects according to a control instruction sent by a control device; the spliced screen is formed by splicing a plurality of display screens;
step S604, adjusting the display attribute of each display object in the display interface according to the notification information, where the display object is an example generated according to a grouping obtained after grouping data to be displayed. Optionally, the display state of each display object may be adjusted according to the notification information, where the display state includes: starting to display the content in the one or more display objects, and closing to display the content in the one or more display objects; the size of the display area of the display object in the display interface can be adjusted according to the notification information; the display position of each display object in the display interface can be adjusted according to the notification information.
It should be noted that the data corresponding to different display objects may be different, that is, different display objects may be generated according to different types of data.
In an optional embodiment, the generation of the instance may be generated according to data to be displayed received from a server, that is, before adjusting the display attribute of each display object in the current display device according to the notification information, the data to be displayed needs to be received from the server; and generating an example according to the received data to be displayed, and taking the example as the display object.
The display objects comprise a main display object and a slave display object; receiving data to be displayed from a server includes: receiving the data to be displayed from the server through a display screen where the main display object is located; and synchronizing the data to be displayed to the display screen of the slave display object through the display screen of the master display object. The above processing procedure may follow a certain specification to achieve consistency of animation of the information piece in the process of cross-screen display, and specifically, a set of frame is designed from the implementation level. The core idea is as follows:
when an information piece embodiment (instance) is generated at a server (server), all display screen (display) ends generate the same information piece instance, however, only one instance (instance) of the display end is the master information piece, and the rest are all the slave information pieces;
each information piece needs to explicitly realize two functions of drawBySyncData and tick, the two functions are called by a frame, and simultaneously, a state needing synchronization is returned through a getSyncData function; the operation flow of the information piece is shown in fig. 7.
function tick (now, delta) is used to update the internal state of the piece of information, such as timing data fetches from the background, or animation calculations, etc. Only master information slice will execute the function, and all the updating operation to the information slice state should be executed in tick function;
function getSyncData () returns the information that needs to be synchronized between different screens, the object is an immutable object, and the frame synchronizes the information to all slave information pieces;
function draw BySyncData (immutab leSyncData) draws the UI from the data returned by getSyncData. The function can only do drawing relative pair operation, and can not have any writing operation to the synchronous state of the information piece;
the drawBySyncData is called by the server in a unified way, namely the information chip receives a drawing command from the server and feeds back an ack signal to the server after the UI drawing is executed; when all the information pieces including the master/slave information pieces complete the feedback, the server issues a new drawing command.
Optionally, the data to be displayed may be received by a browser running on a display screen where the display object is located.
As can be seen from the above description, after an instance is generated according to the received data to be displayed, the instance needs to be set as a dom object in a dom corresponding to the display interface, so as to display an information piece.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present application is not limited by the order of acts described, as some steps may occur in other orders or concurrently depending on the application.
