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, as shown in Figure 2 Show.

[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 ...

Embodiment 2

[0050] As shown in Figure 4, 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 The unit makes corresponding processing after receiving 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]As shown in Figure 5, a control system is added on the basis of Embodiment 1, and the display units are cascaded in star form through control signal lines and connected to the host computer (computer). The host computer includes control software for controlling Each display unit 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.

Abstract

The method for forming high-resolution ratio spliced TV curtain includes: A resolution ratio RGB signal is conducted video processing by a computer, then is conducted division processing through a PCI multi-screen splicing insertion-card to divide RGB signal into m sub signals of lower resolution ratio; Each sub signal is accessed with a distributor and processed by the distributor, then distributes n branch signals accordant with the sub signal; Each of the n branch signals respectively is accessed in a display unit; Each display unit displays the amplified image of corresponding signal region according its position in the TV curtain. The combined display of display units realizes the display of high-resolution ratio RGB signals.

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. ...
