Weak current College】 【LCD display wall (LCD) is becoming a mainstream surveillance command center.

From the application of the Chinese market trend, due to the LCD's vision, highlight high-contrast images of nature, long life and low maintenance rate, in national transport, the transport hub, large venue, and other important parts of the body, increased use of LCD screens in the establishment of monitoring and control command system has become a trend. While Samsung UT LCD mosaic Panel listed in China, 2009, LCD video splice areas market share increase also happens to have multiplied. Special areas in the security monitoring, LCD large screen splicing wall system is gradually replacing the traditional CRT, DLP mosaic wall and become a professional security monitoring splicing large screen's preferred successor.

Senior engineering staff believes that currently in use, LCD products presents three advantages:

One is the combination of casual, use the more flexible

LCD display wall, the number more than mosaic, lines, you can choose any number of columns, you can blend mosaics, special-shaped display that meet more than ordinary monitoring command places, even including the special place of irregular mosaic.

Practical applications, mosaic wall in addition to achieving exactly rejecting and large-screen display, but also to achieve multiple small-screen display. For example, a traffic monitoring center of mosaic wall, more often required while watching all the monitoring point of the screen, when a control point to an exception, you can quickly zoom to full screen for monitoring center all at the same time. This requires in practical application, mosaic wall in the big picture and small screen should achieve good display effect. Combined with Samsung security's 17-inch to 40 inch Samsung LCD monitors to the same quality and standard products are assembled together to best serve the needs of users. This compared to using the DLP and PDP plasma splicing wall, with high resolution, you can size dimensions mixed mosaic, the control unit is relatively simple, etc., is conducive to the needs of the user according to the actual use, reasonable arrangement of the concatenation of the programme, to achieve the size and all the desirable effect.

Second, stable life long, very low maintenance costs

Relative to the PDP, DLP and LCD's life is very long, very nearly and CRT, and power is low, not high calorific value, the failure rate is very low. PDP plasma plasma burn-easy to produce, in a static image appears high brightness may in 5 hours or so there would be a screen Burns; DLP lamp life is only 3000-5000 hours, even if some long-life lamp, are also well below the LCD display. Therefore, when you want to use a 24-hour continuous security monitoring and command center DLP screen wall options, select the Crystal mosaic facade, to better improve utilization, reduce operating costs and maintenance costs.

According to the technical staff, the LCD is currently accepted is best suited for applications in security field professional monitoring terminal products. Samsung as LCD product technology leader, since the launch of mosaic display screen Panel DID achieve the lowest total 6.7 mm joint bilateral mosaic, LCD add-on unit joint specification was smaller than the previous generation upgrade more than 70%. Liquid crystal mosaic products joint technology significantly improving to DLP products such as significant narrowing of the gap also expanded the use of LCD products, liquid crystal mosaic product has entered the mainstream market, market share in the year 2009 has appeared many times over. At present due to liquid crystal mosaic LCD Panel cutting technology bottlenecks resulting from the concatenation of gap problem because of advances in technology have significantly resolved, Samsung LCD mosaic product is only 3 mm in the thickness of the display unit bits of mass production has also been ranked on the agenda, is expected to be officially launched in the second half of 2010. Believe that Samsung LCD display wall full of age coming soon!

The third is color-definition gorgeous, relatively low energy consumption

In the video control, video camera provides the front end of the collection, monitor the Terminal is to complete the back-end video output display. When the camera in the pursuit of high-definition wave, collecting quality continues to enhance the development of the monitor also greeting HD revolution, to make high-definition images really have to be perfectly restored.

In the monitors, large screen splicing wall, DLP and LCD had been difficult to score high, each has unique advantages in the future, this pattern may be a quick change.

It is understood that the DLP stitching on the slit in the smaller display contrast is high, the unit size of lots, but the volume of the DLP mosaic wall and the occupation of an area of relatively large, relatively high power consumption, long work easy to produce brightness reduces. To this end, the market despite use of dust-free, reducing dust falls into the tank to prevent the effects of brightness, and dual lamp technology, built-in two light bulbs, lighting, while at the same time greatly increases the brightness of the screen, but also further enhance the energy consumption of the DLP is not in keeping with modern social demands for low energy consumption.

While the LCD liquid crystal mosaic screen splicing technology is each unit as independent stitching treatment system, enter a full signal and control signal processing by the unit alone, this ensures that each cell of the semaphore is relatively small, fully guarantee the clarity of the image and the video smoothly. 6.7mm ultra-narrow side slit for the eyes of the approximate seamless, more exciting is the 3 new products will be put into mass production, make it more conducive to big-screen splicing, further enhance the overall impressions of the screen.
