In this embodiment, the processing module of the processing server may divide the target image data according to layout information of a plurality of sub-display screens of the display screen in the display screen, to obtain a plurality of sub-target image data.
In the step, after receiving the target encoded data, a processing module of the processing server decodes the target encoded data to obtain desktop image data of the terminal device. Since the display screen includes a plurality of sub-display screens, it is necessary to divide the desktop image data (i.e., the target image data) according to the layout of the plurality of sub-display screens of the preset display screen.
The layout information refers to the arrangement mode of the plurality of sub-display screens in the display screen and the identification of the display screen corresponding to each position of the display screen.
For example, the display screen includes four word displays, and then the four sub-displays may form a large screen device (i.e., a display screen in context) in a "field" layout; the identifiers of the sub display screens which are sequentially arranged from left to right and from top to bottom are respectively '001', '002', '003' and '004'; for another example, the display screen includes nine word display screens, and then the nine sub display screens can form a large screen device in a "nine grid" layout manner; the identifiers of the sub display screens arranged in sequence from left to right and from top to bottom are '010', '011', '012', '013', '014', '015', '016', '017', '018', respectively.
For example, when the large-screen device is composed of four sub-display screens in a display mode of a 'field' shape, desktop image data can be uniformly divided into four small images; for another example, when the large screen device is composed of nine sub-displays in a "box" display, the desktop image data may be equally divided into nine small images.
In an alternative embodiment, after dividing the target image data based on the layout information to obtain a plurality of sub-target image data, the method for displaying data further includes: and encoding each sub-target image data in the plurality of sub-target image data to obtain a plurality of sub-target encoded data.
That is, after the plurality of sub-target image data are divided, it is necessary to encode each sub-target image data to obtain a plurality of sub-target encoded data.
In an alternative embodiment, transmitting the target image data to the display screen to display the target image data with the display screen includes: transmitting the plurality of sub-target coded data to a plurality of receiving terminals based on the layout information, wherein the plurality of receiving terminals are connected with a plurality of sub-display screens; controlling each of the plurality of receiving ends to decode the received sub-target encoded data; and transmitting the decoded sub-target image data to a sub-display screen connected with each receiving end by using each receiving end so as to display the sub-target image data transmitted by each receiving end by using the sub-display screen connected with each receiving end.
In this embodiment, the processing module of the processing server may determine, according to a layout of a plurality of sub-display screens of a preset display screen, a sub-display screen corresponding to each sub-target encoded data, and send each sub-target encoded data to a receiving end connected to the determined sub-display screen in the receiving module of the processing server.
For example, the layout of a plurality of sub-display screens of the preset large-screen device is as follows: the four sub-display screens form large-screen equipment in a 'field' -shaped layout mode, the identifiers of the sub-display screens which are sequentially arranged from left to right and from top to bottom are respectively '001', '002', '003' and '004', and then the desktop image is divided into four small images of an upper left small image, a lower left small image, an upper right small image and a lower right small image; the processing module of the processing server sends the small image coding data (i.e., sub-target coding data) of the small image at the upper left corner to the receiving end of the sub-display screen connection marked 001, sends the small image coding data of the small image at the upper right corner to the receiving end of the sub-display screen connection marked 002, sends the small image coding data of the small image at the lower left corner to the receiving end of the sub-display screen connection marked 003, and sends the small image coding data of the small image at the lower right corner to the receiving end of the sub-display screen connection marked 004.
And after receiving the sub-target coded data, each receiving end restores the sub-target image data and sends the sub-target image data to a sub-display screen connected with each receiving end, wherein the sub-display screen displays the sub-target image data.
In this step, each receiving end may decode the received sub-target encoded data to obtain sub-target image data, and send the sub-target image data to the connected sub-display screen, where the sub-target image data is displayed by the sub-display screen, so that a plurality of sub-target image data form a complete target image data, that is, desktop image data displayed on the desktop of the terminal device.
According to the data display method provided by the embodiment of the invention, firstly, a terminal device which stores data to be put in scans a two-dimensional code displayed by a large-screen device to obtain a connection address of a processing server, and the terminal device collects a desktop image of the terminal device (the data to be put in is displayed on a desktop); then, the acquired desktop image data is sent to a processing server according to the acquired connection address; then, the processing server divides the desktop image data to obtain a plurality of small images (i.e., sub-target image data), sends each small image to each receiving end connected to each display screen, and each receiving end displays the small image on each display screen of the large-screen device. Therefore, the information can be put in the large-screen equipment without uploading the information to the large-screen server, and the safety is high.
