LCD video walls are widely used in various fields, such as shopping malls, exhibition centers, traffic control centers, banks, office buildings, etc. Faced with the application of splicing screens in various fields, people have some understanding of splicing screens, but not comprehensive. Splicing screens are not as ubiquitous as daily necessities, nor can they be bought in stores. Generally speaking, splicing screens are purchased by customers who need to install them from splicing screen manufacturers, and the splicing screen manufacturers install them on site or provide remote guidance for installation. So what exactly is an LCD splicing screen? What are its characteristics? What are the application fields of LCD splicing screens? Let's discuss it together.
Portable LCD video wall has many unique functions. It can be used as an independent display in single-screen mode, and can also be combined into a super large screen through splicing. It can achieve flexible and changeable large-screen effects according to different usage requirements, such as single-screen split display, single-screen independent display, arbitrary combination display, full-screen LCD splicing, double-spliced LCD screen splicing, and vertical screen display. In terms of image display, its border can be compensated or covered, and it also supports roaming, zooming and stretching, cross-screen display and other operations of digital signals, and can set and run various display plans to ensure that full HD signals can be processed in real time.
At present, the mainstream interactive LCD video walls cover sizes of 46 inches, 49 inches and 55 inches, and the seams are of different types, such as 3.5mm, 1.8mm, 1.7mm and 0.88mm. In terms of resolution, the resolution of a single screen below 55 inches is 2K, while the resolution of a single screen above 65 inches can reach 4K. After splicing and combination, the resolution can reach 4K, 8K or even higher.
Features of LCD Video Wall
The LCD video wall uses unique display technology, is equipped with an industrial-grade LCD panel, and is equipped with an industry-leading LCD backlight. Its display screen is high-definition and has an extremely wide viewing angle, up to 178 degrees of full viewing angle, allowing viewers to clearly see the screen content from all directions. It adopts a modular design and has a variety of splicing display methods. It can realize single-screen independent display, multi-screen combination display, or full-screen unified display according to the specific needs of different application scenarios.
The splicing screen is a relatively low energy consumption product among large-screen display devices. Taking a 46-inch splicing screen as an example, its power consumption is only 120W. With this advantage, it can continue to demonstrate its energy-saving and environmentally friendly characteristics. In the long-term use process, it can not only effectively reduce operating costs, but also make positive contributions to advocating a green and environmentally friendly use environment.
Compared with LED technology or DLP technology, LCD technology has better display effects. Taking a 46-inch spliced screen as an example, the resolution of a single screen reaches 1920P, and the panel spacing is only 3.5mm. Through splicing and hardware support, the entire screen can achieve a higher resolution. For example, with 3×5 splicing, the resolution of the entire screen can reach 9600×3240, making the picture display clearer and more delicate.
The splicing screen has excellent durability, and its normal service life can reach more than 50,000 hours. Its operation and display effect will not change over time, which is fundamentally different from LCD and LED displays.
Many terminal display devices will inevitably cause serious damage to themselves after long-term operation, while the LCD video wall supports 7" 24-hour uninterrupted operation, adapting to various working environments that require long-term operation. In some systems that require full-day monitoring, the splicing screen plays an irreplaceable role.
Application Fields of LCD Video Wall
Exhibition Display
With its 178° ultra-wide viewing angle and 4K ultra-high-definition picture quality, the LCD video wall can accurately project audio and video information and stage display content onto the large screen, so that consumers and audiences can obtain relevant information more intuitively. In terms of shopping mall scenes, large screens can attract consumers' attention, increase the probability and time of customers entering and staying in stores, and thus enhance the brand's publicity and influence. At present, as an emerging carrier in the field of commercial display, the application of the commercial LCD video wall in brand stores, hotels, sales offices, cinemas, theaters and other entertainment venues is showing an increasing trend.
Security Monitoring
With the continuous development of high brightness LCD video wall technology, display equipment in the surveillance industry is gradually replaced by splicing screens. The application of splicing screens allows each monitoring screen to be presented in a larger size, and the clarity is significantly improved, so that every monitoring detail can be perfectly displayed. In addition, it also supports diversified processing operations such as enlarging, dragging, and overlaying single or multiple monitoring images. This not only improves the processing efficiency of monitoring information, but also saves a lot of manpower and material resources, and brings convenience to monitoring work. It brings great convenience and advantages, which effectively promotes the development and progress of the monitoring industry.
Subway Station Scene Application
The intelligent transportation system is actually a road traffic information communication system. Its generation and development are based on other different new technologies such as system integration, electronics, communications, and information services. It has now penetrated and applied to new transportation systems in the fields of aviation, water transportation, railway transportation, urban traffic guidance, highways, and subway rail transportation. The construction and use of indoor LCD video wall can not only improve the traffic capacity of the road network and the level of road traffic information services, but also have broad application prospects in the field of environmental protection, promoting the reduction of exhaust emissions and improving energy efficiency.
Installation Method of LCD Video Wall
There are many ways to install LCD video wall. Different installation methods can be used according to different application sites. Currently, the most common installation methods are the following three:
Floor Cabinet Installation
The floor cabinet installation is made of all steel, with a computer gray appearance and static protection. The whole system looks beautiful and atmospheric, and it is also relatively simple if the system needs to be moved.
Wall-mounted Bracket Installation
The wall-mounted bracket installation is to use expansion bolts to fix the bracket on the wall first, and then hang the splicing screen on it. After debugging, it can be installed simply and quickly. However, if there are a large number of splicing screens, the wall may not be able to bear it.
Vertical Bracket Installation
In the vertical bracket installation method, the entire splicing screen system is supported by the bracket, and the splicing bracket must support the weight of the entire system. This installation method requires the installation ground to be flat and strong enough, and also has relatively high requirements for the splicing bracket. This installation is conducive to system maintenance and troubleshooting.
