Intelligence may become a new direction for the development of large-screen splicing in the future
According to data, the domestic large-screen splicing display market has reached 4.8 billion yuan in 2010, of which DLP rear projection splicing accounts for about 77%, and flat panel splicing accounts for about 23%. The overall large-screen splicing market will grow in 2011. 42%, achieving total sales of 6.81 billion yuan. The ultimate strength of the large-screen splicing 'power' is still due to market demand. According to the reporter's understanding, as early as 1995, large-screen splicing had just appeared in China. At that time, many manufacturers imported splicing screens from abroad, which was not only costly, but also could not guarantee the safety and reliability coefficients in use. Huge capital investment, so that buyers are not very happy to buy large-screen TV walls with no safety factor. However, with the development of the broadcasting and television industry, the demand for large screens in live news rooms is increasing. Many broadcasting and television manufacturers have begun to seize the tail of the opportunity, and China's large-screen splicing market has opened up. With the rapid development of my country's economy, various kinds of information are also growing rapidly, and the amount of information that each enterprise or unit needs to watch and monitor is also increasing. This urgently requires the development of large-scale and high-definition terminal display systems. The large-screen display system has the characteristics of large screen and high-resolution, and can provide users with a large amount of information. It is welcomed by many industries and departments such as radio and television, public security and transportation. As an important large-screen display device, LCD splicing curtain wall is widely used by radio and television. In order to realize the function of splicing a TV wall with multiple liquid crystal display units to display a large screen. The future development direction will be towards digital, high-definition, and intelligent development. Digital high-definition The current LCD splicing video wall mainly uses composite video interface, VGA interface, DVI interface and other common security monitoring interface technologies. These interfaces cannot achieve 1080p high-definition display. With the development of technology, people urgently need a digital high-definition LCD splicing video wall, but the traditional composite video interface, VGA interface, DVI interface obviously can not meet such requirements. At present, there are many interfaces that can realize digital high-definition display, such as the HDMI interface for TV and the new DiiVA interface, but these digital TV-based interfaces are not suitable for the use of security monitoring, such as interface incompatibility, short transmission distance, etc. problem. The digital high-definition LCD splicing video wall must have HDTV video quality high-definition video surveillance. Therefore, adopting a suitable interface compatible with the existing system is the key to achieving digital high-definition. The broadcast monitor adopts the HD-SDI interface, which is fully in line with the development requirements of digital high-definition, and has the advantages of long transmission distance, compatible interface, standard can be based on, plug and play, etc. It is an LCD splicing TV wall to achieve digital high-definition Important direction. Intelligent LCD splicing video wall, the embedded system is becoming more and more powerful, and more intelligent designs will be incorporated in the future, making the system operation more convenient and faster. Intelligence is, of course, system debugging first. The LCD splicing TV wall is composed of multiple LCD splicing units. Because of the differences between the units, it is very important to ensure the consistent display of unit colors and geometry. The traditional method is to slowly adjust and calibrate the LCD spliced u200bu200bTV wall through equipment and visual inspection. The intelligent design method is to use the system function to automatically adjust with one button, and easily complete the original complex adjustment process.
