In all walks of life, large-screen splicing display systems are mainly used to display a large amount of dynamic graphic image information, such as: video images, computer and workstation images, network information images, etc. The display mode of this information can be single-screen display, arbitrary window opening, arbitrary roaming, full-screen display, etc. However, each industry has different situations and its application methods have their own characteristics.   In addition, different types of large-screen splicing display walls also have their own different advantages, but also have their own specific demand environment. Therefore, along with the development of products during application development, the direction of the future large-screen splicing display wall is closely related to the application. In the professional field, the popularization of electronic and digital operating systems has made users' demands for high-resolution and super-large image display increasingly urgent. The display of information has been solved by only one or two projectors in the past. It is gradually replaced by a large-screen splicing display system. The large-screen splicing display system has been widely used in control rooms in many fields such as telecommunications network management, public security traffic police command, traffic monitoring management, military combat command training, industrial production scheduling, etc. It can centrally display RGB, Video and network Such as signals from a variety of different signal sources to meet the needs of users to display a variety of shared information and comprehensive information on a large area.  In the future, large-screen splicing displays will develop diversifiedly.    Various types of splicing walls are competing with different technologies. DLP rear-projection large-screen splicing display is limited by volume, service life and maintenance cost, and its market share is shrinking year by year. NICEVIEW LCD large-screen splicing display wall has the advantages of thin thickness, light weight, low energy consumption, long life, no radiation, etc. , And its exquisite picture, high resolution, excellent performance of various key performance indicators, has gradually won the market's acclaim.   In the future, the splicing wall will be networked and its functions will be further enhanced. It can not only perform terminal display, but also add some practical functions to achieve value-added. The most important thing is to realize household consumerization. At present, security products are not only used in public places and commercial fields. More and more families are gradually adopting security products to protect their private places. Therefore, security requires not only industrial products, but also consumer products, which enable large screens. Splicing displays gradually move from high-end to low-end.  The large-screen splicing display system is more complete and perfect  A perfect picture will always give people an extraordinary vision. With the continuous technological research of LCD panel manufacturers represented by Samsung and Sharp, the splicing seams of large LCD screens are getting smaller and smaller, making the spliced u200bu200bsystem pictures more complete and perfect.  Multiple splicing methods embedded in the general trend.  There are basically three different splicing methods for large-screen splicing display walls on the market. One is PCI plug-in card type; the other is external drag splicing controller method; the third is embedded. The working principle of PCI plug-in card is to use a multi-screen splicing card through an industrial computer to first divide a complete video image into mХn sub-video signals, and then transmit these sub-video signals to each corresponding unit on the splicing screen wall. To achieve the purpose of large-screen splicing display.   However, due to the limited computing power of the industrial computer, a current industrial computer with the best performance can only achieve 4Х4 splicing, which limits the number of spliced u200bu200bunits. The external drag splicing controller can also be called a large-screen display splicer or a TV wall controller or a TV wall splicer. Its main function is to divide a complete image signal into N blocks and assign them to N video display units (such as back Projection unit) to complete a large screen with multiple common video units.   It can support simultaneous access of multiple video devices to meet the functional requirements of splicing curtain walls. It is called external drag because this kind of splicing curtain wall is divided into two independent parts, one part is the display part, which can be composed of ordinary large-screen splicing display units such as LCD splicing screen; the other part is this splicing control Its function is to realize that multiple physical outputs are combined into a display output with superimposed resolution, so that a picture can be displayed on the screen. '   The working principle of the embedded large-screen splicing display wall is that each splicing unit has an independent video processing module, and the complete signal is transmitted to each unit through the matrix, and the video processing is performed separately to separate the part that should be displayed. This part of the signal is amplified and displayed to achieve the purpose of large-screen splicing display. Because of the separate processing, the number of spliced u200bu200bunits can theoretically be unlimited.
