Obviously, the described embodiments are part of the present invention. examples, but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example 1

FIG. 1 is a schematic diagram of data to be displayed on a smart city comprehensive data billboard platform provided by an embodiment of the present invention. As shown in FIG. 1 , the platform includes: a large screen formed by splicing M*N displays, a control center and a screen-casting computer, wherein the screen-casting computer is communicatively connected to a control center, and two monitors are connected to the screen-casting computer, and one of the monitors displays data to be displayed; the control center is used to receive the to-be-displayed data. and obtain the aspect ratio of the data to be displayed; when the aspect ratio of the data to be displayed is greater than the aspect ratio of the large screen, the display area of the large screen is divided into at least two sub-sections according to the upper and lower order, in which A subsection projects the data to be displayed; when the aspect ratio of the data to be displayed is smaller than that of the large screen, the display area of the large screen is divided into at least two subsections in left and right order, and the screen to be displayed is projected in one of the subsections. Display Data.

Exemplarily, when a user uses the data signage platform, he usually connects a computer to the control center for communication. The computer can be connected with two monitors, or more than two monitors can be connected. The present invention uses two monitors connected to the computer. display as an example. The aspect ratio of a computer screen is usually 16:9. The large screen is composed of 21 55-inch 16:9 1080P LED screens spliced together, which is a 7*3 LED large screen matrix. Since the aspect ratio of the computer screen is inconsistent with the aspect ratio of the large screen, if the large screen is covered, the interface of the data to be displayed will be deformed. The data to be displayed is directly projected to the screen.

Exemplarily, the control center in the embodiment of the present invention first obtains that the aspect ratio of the data to be displayed is 16:9; the aspect ratio of the large screen is 16*7:9*3; then the aspect ratio of the data to be displayed is 16*7:9*3; The ratio is smaller than the aspect ratio of the large screen. Therefore, the large screen can be divided into left and right subsections, and the aspect ratio of each subsection is: 16*3.5:9*3. On the subsection on the left, project the monitor A for displaying the data to be displayed, and on the subsection on the right project the monitor B for displaying other data. Both the monitor A and the monitor B are connected to the host of the same computer. In this way, the aspect ratio of the data to be displayed can be closer to the aspect ratio of the subsection, thereby reducing distortion. Especially when displaying a video, it will cause the video to be blurred and produce jaggedness in the video, which will lead to more prominent video distortion problem, and the human eye cannot obtain effective information from it. Therefore, the above method is especially suitable for video screen projection display.

In addition, in the embodiment of the present invention, the two sub-sections are displayed separately on the left and right, so that the kanban can be visually integrated as a whole.

The display computer uses "one machine with two screens" for display. There are 8 DP multimedia sockets on the rear panel of the computer, and 4 display cables are inserted in total, 2 of which are the computer's own dual monitors, and 2 are the input channels of the splicing controller. line for large-screen display.

The splicing controller has 16 inputs and 24 outputs, and the highest supported resolution is only 1080P.

After testing, if the entire computer screen is projected and displayed, the video on the page is blurry and unclear. Using dual-screen splicing display can make the picture quality clearer.

Preferably, the control center of the Kanban platform uses the Winform architecture, and the control center can be set to a "one machine with two screens" display mode. Realize splicing display and page switching, thereby improving the overall display effect of the Kanban board.

Preferably, the Kanban control center also supports keyboard shortcut keys to control page switching. The shortcut keys are as follows: return: "Alt+F", refresh: "Alt+R", close: "Alt+K".

Preferably, the kanban maintenance module is a separate platform that can configure and maintain various data and video points of the kanban data module in the integrated data kanban.

In a further embodiment of the embodiment of the present invention, when the aspect ratio of the large screen is greater than the aspect ratio of the computer display, and less than twice the aspect ratio of the computer, two displays A and B are connected to the computer, The large screen is divided into two parts left and right, the content of display A is displayed on the left, and the content of display B is displayed on the right. Similarly, if the aspect ratio of the large screen is greater than twice the aspect ratio of the computer monitor, but less than three times the aspect ratio of the monitor, you can connect three monitors A, monitor B and monitor C to the computer, which will The screen is divided into three parts on the left, middle and right. The content of display A is displayed in the middle left, the content of display B is displayed in the middle, the content of display C is displayed on the right, and so on. By applying this embodiment of the present invention, the display area of the large screen can be more accurately divided left and right, so that the aspect ratio of the divided sub-sections is closer to the aspect ratio of the computer monitor.

Finally, the embodiment of the present invention adopts direct screen projection display, which saves the calculation process and reduces the delay of screen projection compared to the method of proportional enlargement in the prior art.

It should be emphasized that, in order to avoid the difficulty of dividing the large screen, avoid the display display in the middle part of a large screen being divided into two parts, and cut the left and right sides of the large screen unequally. That is, in the above-mentioned embodiment of the present invention, there are 7 displays in the horizontal direction of the large screen. If it is divided into equal parts, the left side of the display in the middle column will display the data in the display A, and the right half of the display will display the data in the display B, which will increase the The difficulty of dividing the display in the middle column increases the difficulty of signal processing; further, the large screen can be divided into 4*3 displays and two sub-parts consisting of 3*3 displays respectively, and the aspect ratio is closer to the data to be displayed. A subsection of the aspect ratio displays the data to be displayed, or a subsection with a larger area is used to display the data to be displayed.

Example 2
