Video walls installation is not like ordinary display equipment, just a simple put on the installation. video walls installation should not only carefully choose the site of installation, but also need to pay attention to the light around the installation environment, but also need to pay attention to the wiring, and for the frame also has requirements.
Installation of the ground selection
Video walls selection of the installation ground to be flat, because the entire system of video walls whether in volume or in weight are relatively large. The choice of ground also needs to have a certain ability to withstand the weight, if the ground is tile, it may not be able to withstand its weight. Another point is that the installation of the ground to be able to anti-static.
Wiring considerations
When installing the video walls, pay attention to the wiring to distinguish its power lines and signal lines, installed in different places to avoid interference. In addition, according to the size of the video walls and installation location of the entire project, calculate the length and specifications of the various lines needed to calculate the entire project needs.
Environmental light requirements
Video walls brightness is very high, but after all, it is still limited, so choose to install the environment around the light can not be too strong, if it is too strong, it is possible not to see the display on the screen. The light that may be coming in near the video walls (such as windows), if necessary, to block, while the equipment running lights are best turned off to ensure the normal operation of the equipment. Do not install lights directly in front of the video walls, just install downlights.
Frame requirements
In order to make the maintenance of the video walls more convenient in the future, the frame wrapping must be removable wrapping. Outside the frame edge from the outside of the spelling walls on each side of the gap of about 25mm, large spelling walls should also be appropriate according to the number of columns to increase the margin. In addition, in order to enter the box maintenance later, the maintenance channel is in principle not less than 1.2m wide. Removable side bar to press the edge of the video walls 3-5mm is appropriate, in the box and video walls completely installed in place, and then finally fixed removable side bar.
Ventilation requirements
In the maintenance channel, air conditioning or air vents must be installed to ensure good ventilation of the equipment. Vent location should be as far away from the LCD video walls (about 1m better), and the wind from the vent cannot blow directly against the box, so as not to damage the video walls hot and cold unevenly.
In the LCD video walls construction site, installation and debugging to determine its cause according to the phenomenon reflected in the failure, to focus on checking the synchronization interface and transmission cable of the device, as well as against the signal source and display terminal synchronization frequency range. If the image has ghosting, check whether the transmission cable is too long or too thin, the solution is to change the line test, or increase the signal amplifier and other equipment. If the focus is not ideal, you can adjust the display terminal.
In fact, many current video walls construction, selection simply does not meet the specifications, even if the choice of foreign brands. Many large-screen display projects do not fully play the advantages of the video walls, and did not achieve high-definition effect, the minimum spacing. From a microscopic analysis, more companies only know the installation, lack of negligence to master the necessary knowledge.
1. Video walls and other computer monitor comparison advantages
video walls using the A-class LCD panel, high trustworthiness to ensure quality display on the large video walls, the role of the LCD panel is undoubtedly the most important, which accounts for about 70% of the cost, and the general display to choose A-class panel will appear to build elevated. At present, the LCD panel is divided into A +, A-, B +, B-, computer monitors choose B + panel is very good, but the video walls application environment also determines the LCD panel requirements are high.
2. Video walls ultra-narrow bezel design
Video walls to the bezel, both sides of the slim design, the use of less than 1 mm row line, significantly better than the general display equipment BSV LCD video walls technology. It is bound to set off an LCD seamless video walls craze in the field of surveillance.
3. Video walls using high-quality electronic components (IC, capacitors, inductor coils, etc.)
Video walls product quality, with strict component selection system and perfect production line. For each production line of the product factory have gone through a strict baking machine and testing. And not like the "other machine", the factory when the panel procurement time is very compact, production and assembly at will on the factory. IC, capacitor, inductor coil quality is good and bad is directly affect the life of the display and the use of security.
4. Video walls has DNIE Pro color and signal enhancement complementary unique technology
For LCD monitors, restore the color of the precise control of the control IC, can make the LCD display effect more colorful. Its control IC can filter out 1 billion best colors from about 686 billion colors, more accurate in restoring the color of objects. And the general display signal motherboard simply decodes the signal directly displayed, and not through the IC processing.
5. Video walls with dynamic reinforcement signal, to ensure that the black and white sunken color and dynamic trailing phenomenon
Display IC chip and control circuit design, material selection is also extremely important, a large factory itself has a panel production line, can be the most professional perspective on the control circuit design and development, from the material to workmanship to ensure that the large video walls can be a long-time stable work, while all kinds of input signals to strengthen the processing, to ensure the effectiveness of the gray scale.
