Problems solved by technology

Because it is processed separately, the number of spliced ​​units can be theoretically unlimited, but the memory of each module of embedded splicing is too small, and the video processing capability is limited, so high-resolution display cannot be realized.
At present, the embedded splicing curtain wall can only achieve a resolution of 1600×1200. When the number of spliced ​​units is small, this resolution can achieve the ideal effect; if the number of spliced ​​units is large or the customer requires a higher resolution, Embedded methods seem powerless

Embodiment 1

[0032] The splicing TV curtain wall system realizes a total of 80 liquid crystal display units of 10×8 to display an image, and the system realizes a resolution of 2560×2048.

[0033] The implementation steps are as follows:

[0034] 1. According to the position of the display unit in the TV curtain wall, the curtain wall is divided into four areas, namely A area, B area, C area, and D area. Each area has 5×4 display units, such as figure 2 shown.

[0035] 2. A 2560×2048 high-resolution RGB signal is divided and processed through the PCI multi-screen splicing card. The processing equipment and method are as follows:

[0036] An ordinary plug-in splicing controller, its main structure includes:

[0037] System structure: computer structure, 1 PCI slot;

[0038] Input RGB: 1 channel high-resolution signal;

[0039] Output channels: 4 in number, output resolution 1280×1024 pixels;

[0040] System control: keyboard and mouse.

[0041] Through the above-mentioned ordinary pl...

Embodiment 2

[0050] Such as Figure 4 As shown, a control system is added on the basis of Embodiment 1, and the display units are cascaded in series through the control signal line, and the control signal of the upper computer (computer) is transmitted to the display unit through the control signal line, and the display unit receives Corresponding processing is made after the control signal belonging to itself, and the display unit forwards the control signal not belonging to itself to the next display unit.

[0051] The control signal can adjust the image position, magnification, brightness, contrast, saturation, definition, etc. of the display unit, so that the mosaic TV curtain wall can achieve excellent display effect.

Embodiment 3

[0053] Such as Figure 5As shown, a control system is added on the basis of Embodiment 1, and the display units are cascaded in star form through the control signal lines, and are connected to the host computer (computer). The host computer includes control software for controlling each display unit , the image position, magnification, brightness, contrast, saturation, clarity, etc. of the display unit can be adjusted, so that the mosaic TV curtain wall can achieve excellent display effect.

Abstract

The invention discloses a high-resolution mosaic TV curtain wall and a composition method thereof. A composition method of a high-resolution splicing TV curtain wall: a high-resolution RGB signal is processed by a computer, and then split by a PCI multi-screen splicing card, and the RGB signal is divided into m lower-resolution sub-signals , to realize the combination of high-resolution signals converted into multiple lower-resolution sub-signals; each sub-signal is connected to a distributor, and after being processed by the distributor, each sub-signal is distributed with n sub-signals consistent with the sub-signal; n Each branch signal is respectively connected to the display unit; each display unit displays the enlarged image of the corresponding signal area according to its position in the TV curtain wall; the combined display of the display units realizes the display of high-resolution RGB signals. The invention realizes large-scale, high-resolution image display, and can be used in monitoring systems, large-scale performance venues or video conferences and the like.

Description

technical field [0001] The invention relates to a spliced ​​TV curtain wall and its composition method, in particular to a high-resolution spliced ​​TV curtain wall and its composition method. Background technique [0002] The splicing TV curtain wall has been widely used in 110 command center, railway (subway), port, dock monitoring system, intelligent traffic management monitoring center, national defense or military monitoring system, power dispatching monitoring system, large factories and mines monitoring system, financial management monitoring system, TV station Or large-scale studio center monitoring curtain wall, background curtain wall of large-scale performance venue, video conferencing, etc. For example, in the 110 command center, it is necessary to monitor the traffic conditions of each traffic artery at the same time, and a large number of video signals are input at the same time. At this time, a device that can display these signals at the same time is needed. ...
