LCD splicing is used in commercial applications, from the beginning of the more professional and high-end applications to the current coverage of commercial, entertainment, public management and other sub-application areas. LCD splicing is increasingly used in the commercial field with clear image quality, ultra-thin volume and flexible splicing.

In addition, the technological development in other fields has gradually merged into the field of liquid crystal splicing, which has led to the upgrading and development of LCD splicing technology. The combination of intelligent control and network technology and liquid crystal splicing technology makes the liquid crystal splicing system gradually become intelligent, easy to network transmission and control, and more able to meet the diverse needs of users.
It is understood that the advantages of LCD splicing can be divided into the following three points to describe:
First, the practicality of LCD splicing
LCD splicing has a large combination space: it can be used for small screen splicing or large screen splicing; it can be spliced ​​one-to-one with single screen, or with a pair of M×N full-screen splicing; According to the customer's system scale and application requirements for the LCD splicing curtain wall system, according to the system's use environment, select the appropriate product and splicing method, design the specific implementation plan to meet the application requirements of the system.
According to the user's requirements on the input signal, different video processing systems can be selected to realize VGA, composite video, S-VIDEO, YPBPR/YCBCR or DVI signal input, which can meet the requirements of different use occasions and different signal inputs. It is also possible to realize various signal switching, splicing into full-screen display, arbitrary combination display, image stretching display, image roaming display, image superimposition display, etc. through control software.
LCD splicing can be customized to meet different needs of customers, providing different implementation solutions and technical support.
Second, the reliability of LCD splicing
Monitors and splicing curtain walls generally require 24 hours a day, 365 days a year to work continuously. This requires the reliability of the monitor and the splicing curtain wall to be stable and reliable.
The impact on system reliability mainly includes temperature rise, structure, interference, and the service life of the system itself. The large amount of heat generated by the system will greatly reduce the service life of the system components, and if the equipment is heavy, it is not conducive to installation and the rack is overwhelmed. In addition, the system's anti-interference ability also directly affects the reliability of the system.
LCD splicing uses high-reliability DID LCD screen, 40 of which is only 12.5KG, which is the lightest of the same size flat panel display devices, with a power consumption of 150W, so low energy consumption, its heat is very small, so that it stands In front of the splicing wall, it does not feel its temperature rise. The unique display principle of liquid crystal, the all-digital driving system, and the air eddy current cooling method designed by engineering fluid mechanics ensure the high reliability and stability of the splicing wall, while the all-steel curtain wall frame and reasonable process design make The device is neither radiated nor interfered by external electromagnetic fields, and is stable and reliable.
The liquid crystal has low power consumption, low heat generation, light weight, long life, no radiation, etc., which makes the liquid crystal splicing reliability extremely high, and generally can work normally for more than 50,000 hours.
Third, the economics of LCD splicing
Considering the economics of the system, it should be considered from the cost performance. Only under the premise of high performance and high quality, the economics of the system will make sense.
At present, the price of plasma (PDP) splicing wall on the market is relatively high. Generally, the price of one square meter is as high as 100,000, which is more expensive than the liquid crystal splicing wall, and the cost performance is lower due to its inherent defects. DLP TV wall, although the price is relatively low, but the replacement cost of light bulbs for a year is as high as several thousand pieces per screen. One curtain wall adds up to tens of thousands, and more than 100,000. In a few years, the cost is amazing.
LCD splicing has been widely welcomed at home and abroad for its excellent performance and reasonable price. It has a service life of up to 50,000 to 80,000 hours, stable quality and low maintenance cost. It is the most cost-effective large-screen splicing.
In summary, the emergence of LCD splicing solves the various shortcomings of traditional TV curtain wall, providing convenient, comprehensive and real-time display of video information of various systems, especially for remote real-time command, scheduling and other projects to provide the best large screen display. system. LCD splicing wall is the most practical, advanced, reliable and economical large-screen display device.
