For many years, the CRT video wall was the main display terminal for video surveillance. With the technological development of the display industry, CRT TV walls gradually withdrew from the market, flat panel monitor groups, large-screen monitors, etc. became the mainstream products in the security monitoring market. Under the requirements of small-scale, pure video surveillance applications, the above methods can basically meet business requirements. With the high-definition acquisition, codec, and network transmission increasingly becoming standardized configurations, especially the transition from single video signal display to complex signal display including video signals, network signals, GIS and GPRS signals, simple security monitoring has developed into a set. Integrated applications such as video surveillance, dispatch control, emergency command, remote collaboration, interactive seminars, system linkage, etc. The monitoring system starts with more IT systems, GIS systems, GPRS systems, production management systems, operations management systems, dispatch systems, and command systems. The system realizes seamless connection to achieve the goal of unified management and centralized control of the business. Graphical and visual processing of non-image and video signals to achieve more visual and intuitive reflections and integration analysis of diverse information have become the focus of system development. Traditional CRT video walls, monitor groups, projections and other technical means Increasingly, it has become an embarrassment for the development of the security industry.
Faced with the above requirements, the large screen display wall capable of accessing and displaying a variety of signal sources without being limited by the size of display products has become an essential choice for the development of the security industry, and an ultra-high resolution large-screen splicing display wall system is such a product. It uses a multi-screen display with an ultra-narrow bezel to splice into one large screen, and utilizes a signal processing device to splice this large screen into a single logic display with ultra-high resolution and can be connected to display various active video/RGB. / Network signal, signal display in the form of open windows, the window can be arbitrarily zoomed in and out, free movement, etc., to fully meet customer demand for centralized information display, centralized monitoring, centralized command and dispatch.
In the early years, digital display splicing walls dominated by rear projection DLP technology could not fundamentally overcome inherent deficiencies such as huge size, low brightness and low contrast, high procurement and maintenance costs, and complicated installation and maintenance, especially in terms of price and maintenance costs. Far beyond the tolerance of the security monitoring market, the application of the large-screen splicing display system is limited to government and pan-government agencies, and a control room market with command and dispatch as a typical business is formed. With the introduction of the flat panel display system represented by MPDP plasma splicing, MLCD liquid crystal splicing, etc., its excellent display performance, ultra-thin volume, and extremely low procurement and maintenance costs, the flat panel splicing display system has become inevitable in the security market. select.
Comparing flat panel display technology with mainstream product model Flat panel display technology mainly includes PDP plasma seamless display system and ultra narrow LCD liquid crystal display system. According to statistics, as of 2010, the market share of the flat panel display system has reached a new high, with the market share of LCD liquid crystal wall nearly 25%, and the average growth rate of the past three years exceeds the DLP market by 10%. The market share of MPDP remains above 15%, and the market share of flat panel display systems is close to half. In particular, in recent years, the key technology of flat panel display has made a revolutionary breakthrough, further enhancing the market competitiveness of flat panel products, including:
As the seams continue to shrink, the narrowest seam of MPDP's seamless splicing products has exceeded 1mm (OPM-4250, OPM-4260 by Dehao), achieving the effect of seamless splicing; the stitching of ultra-narrow LCD liquid crystal splicing products Has reached 6.3mm (De Hao Technology introduced LG47 inch WV30). The narrowing of seams provides the possibility of satisfying the refined display of digital signals.
In terms of signal interfaces, the all-digital signal interface became standard, and the display of various resolutions, such as Full HD and WXGA, was basically realized.
The fast-growing market attracts more and more flat-panel product suppliers. Among them, DET Dehao Technology has nearly 10 years of experience in panel splicing, the most complete flat panel splicing product line and the most professional technology and service level. , In the flat panel display industry occupies an important position.
With the richness of the flat panel display product line and the cost reduction, especially the security market itself has evolved from the early video surveillance to the integrated application stage, and the combination of the two has become an inevitable trend.
The security market introduced a flat panel display system. In addition to replacing the monitor group and large-screen monitors, it brought a multi-billion-dollar market increase. The greater significance is that it can directly draw on the mature application solutions in the control room market for the security industry. The industrial upgrade provides an important guarantee. The combination of the flat panel display display product and the security market breaks through the existing narrow control room market, will further reduce product costs, and drive the entire large-screen display industry into a new era of flat panel stitching
