A video wall is a special multi-monitor setup that consists of multiple computer monitors,video projectors, or television sets tiled together contiguously or overlapped in order to form one large screen. Typical display technologies include LCD panels,Direct View LED arrays, blended projection screens,Laser Phosphor Displays, and rear projection cubes.   Screens specifically designed for use in video walls usually have narrow bezels in order to minimize mullion, the gap between active display areas, and are built with long-term serviceability in mind.Such screens often contain the hardware necessary to stack similar screens together, along with connections to daisy chain power, video, and command signals between screens.A command signal may, for example, power all screens in the video wall on or off, or calibrate the brightness of a single screen after bulb replacement.   Reasons for using a video wall instead of a single large screen can include the ability to customize tile layouts, greater screen area per unit cost, and greater pixel density per unit cost, due to the economics of manufacturing single screens which are unusual in shape, size, or resolution.

    With the development of LCD technology, in order to ensure the LCD splicing screen picture complete, clear, fluent, this is for LCD splicing screen installation put forward higher requirements. The application of liquid crystal splicing wall covering security, entertainment, advertising, catering, real estate, teaching all walks of life, such as the use environment are increasingly more and more complex. Shenzhen DDW technology co., LTD. As a professional LCD splicing wall manufacturers, with years of experience in technology and vast amounts of field installation, sums up the following screen and the experience of installation, to share and improve together.       A connection, bracket fixed rod   In LED after maintenance system, the installation of the bracket rod connection is the most important, once the pull rod fixed to complete, system installation is quite easy, panel debugging is convenient and quick. Conversely, the debugging process is more trouble than a DLP large screen system.       1, due to the LED LCD splicing screen top-heavy, not as stable as the DLP splicing screen, itself can't balance. If there is no fixed rod help, vertical degree doesn't guarantee system. So, when installation should before after adjusting base stents, hanging panel, install a fixed rod. This can not only guarantee the verticality of the whole system, also can ensure the stability of the whole system.       2, because the new bracket is not a whole, it's about connecting rod through connect each row frame, and so lead to each row rack is very difficult to guarantee completely in the same plane. That was hard to hang up the panel after large concave and convex (not enough amplitude adjustment of adjusting screw panel). Solution is listed in each frame is installed above a fixed rod, so you can easily adjust the before and after the difference between each row frame.       3, fixed rod must back, there is a pull back to guarantee the stability of the system, and to realize the adjustment of the 2 points mentioned above. Found that when the actual installation, fixed in vertical way, even the rod slightly lean back, after repeated testing, the system is still not stable.   Second, the adjustment of the LCD panel       1, adjust the panel flatness can be before all the panel flatness of unified adjust the adjusting screw to screw the intermediate position of the adjusting amplitude, and then began to adjust the flatness of panel. This can maximum limit to ensure every Angle panel has certain adjustment range, and there will not be the last individual panel is unable to adjust the adjusting screw.       2, when the control panel can adjust the high and low levels of panel, first and then adjust the concave and convex of panel, because adjust the high and low levels of panel, panel will move around or before and after.   Three, the installation of the panel   Under normal circumstances panel installation and no special, panel raised more than support bearing bar can be put down after. But if you have installed above does not have the space? In this case, can hang panel after two hang lever in the bracket of bearing on a rod, and then carry the panel on the installation position, let the people behind the hang lever and panel between the screw twist

    Face full of beautiful things in eyes, type of product, already let the consumer dazzling, how to choose and buy quality, higher ratio of splicing wall products, and many users are headache. Many specifications without a mandatory standards, encounter problems don't know what aspect, thus the right to choose the LCD splicing screen is very important. No can be accomplished without norms or standards, the following is the emperor ai emperor for everybody finishing top 10 standard about the LCD panel.     1, be sure to choose has passed the national legal quality supervision and inspection department and the relevant administrative departments of certification and allow the production and sale of products, such as the DDW, its product quality and technology should comply with the requirements of relevant national norms and standards.     2, LCD splicing screen the actual technical indicators should be consistent with product instruction is given, instruction given on the technical indicators should be detailed and specific.     3, the technical indicators for the selected liquid crystal splicing screen, usually should be higher than the technical indexes of the whole system.     4, to the requirement of the size of the LCD splicing screen, choose is: the greater the size, of course, is the better, the emperor of emperor ai LCD splicing screen splicing gap as low as 3.5 mm, almost seamless splicing, since joining together the smaller aperture, the greater the effect of this perspective, the better.    5, choosing the LCD splicing screen, preferably with a fan, or pay attention to maintenance of LCD screen, use a fan or adjust indoor temperature, to extend the life of the LCD screen.     6, had better choose metal shell LCD splicing screen, the LCD splicing screen has good shielding performance, (especially) after its enclosure grounding is not easy to suffer the space magnetic field interference.     7, the position of the LCD splicing screen equipment, should make strong shot screen is not affected by the outside world. When there are inevitable light incident, should take corresponding measures to avoid light. (outdoor LCD screen according to environment to purchase corresponding material and brand)     8, quantity: LCD splicing wall configuration can be determined according to the Numbers of the scene and the camera, generally USES the way of 4:1, if space is limited in the LCD splicing screen two configuration several small size LCD monitors.     9, clarity, should according to the resolution of the camera used indicators, with a high resolution LCD splicing screen, LCD splicing the brightness of the screen are now better, 450 CD / 700 CD.     10, liquid crystal splicing wall Settings should be unified with the design of the monitoring center, reasonable layout, convenient operation, easy maintenance.     The LCD splicing screen     Seamless liquid crystal Mosaic is the most important part of the screen display, we mainly from the display brightness, color reduction degree, visual Angle and flat-fell seam size for the discrimination of subjective consciousness; At the same time to carefully observe whether the overall structure of the liquid crystal splicing screen is strong, its appearance design is reasonable. In practical applications, the LCD splicing screen require hours of uninterrupted work, so its overall structure and firm performance is very important, directly affect the use effect of the product.     Until today in development of DDW LCD splicing, flat-fell seam breakthrough, environmental protection, high definition has been an indispensable part of the LCD splicing industry, but technology is not enough, the service is necessary. After-sales service has always been the most high-profile link consumers, especially for large screen splicing products, from the installation, commissioning, maintenance, maintenance of the whole system and so on a series of work, big screen splicing system complex, high technical content, system users for the dependence of the after-sales service is very high, so in addition to technology, a perfect after-sales and LCD splicing is an important indicator of the long-term development. DDW application field of liquid crystal splicing screen has across government, transportation, energy, finance, radio and television, entertainment, health care, education, business and other industries.
