Senior people: LCD products show three major advantages

Editor's note: As the security industry continues to expand, the market share of LCD in the field of video splicing has also doubled. LCD large-screen system video wall is gradually replacing the traditional CRT, DLP video wall, becoming the preferred successor of professional security monitoring and splicing large screen. Industry veterans analyze the three major advantages LCD products present at this stage.

First, the combination of random, use more flexible LCD mosaic wall, not only the number of mosaic, the number of rows, the number of columns can be arbitrarily selected, but also can be mixed splicing, profiled display, which meets more than the general monitoring command places, even including special Site shaped splices need.

In practical applications, in addition to realizing a full-screen large-screen display, a multi-screen small-screen display must also be implemented. For example, a splicing curtain wall of a traffic monitoring center more often requires the realization of simultaneous viewing of all monitoring points. When an abnormal situation occurs at a monitoring point, it can quickly zoom in to the full screen for monitoring center owners to watch at the same time. This requires that in actual use, the splicing curtain wall should achieve a good display effect on both large and small screens. The combination of Samsung Security's 17-inch to 40-inch LCD monitor and Samsung's combination of the same quality and standard products can meet the needs of users to the greatest extent. Compared with using DLP rear projection and PDP plasma splicing curtain walls, it has the advantages of high resolution, mixed splicing of large and small sizes, and relatively simple control unit. It is beneficial to the user's rational arrangement of splicing plans according to actual needs, and can achieve large and small matching. Each has its own effect.

The second is stable long life, low maintenance costs. Relative to DLP and PDP, the service life of LCD is very long, almost the same as CRT, and the power is low, the heat is not high, and the failure rate is very low. PDP plasmas are prone to plasma imprints. When high-brightness static images are displayed, screen burns may occur in about 5,000 hours. DLP lamps have a lamp life of only 3,000 to 5,000 hours, even if they are long-lived bulbs. Lower than the LCD display life. Therefore, in the choice of 24 hours of continuous use of security monitoring and command center large screen splicing curtain wall, choose LCD splicing curtain wall, it can better improve the use rate, reduce the use of cost and maintenance costs.

According to the introduction of relevant technical personnel, liquid crystal is currently recognized as the most suitable product for professional surveillance terminals in the field of security. As a technology leader in liquid crystal display products, Samsung has improved the seaming technology of liquid crystal splicing units by more than 70% compared with the previous generation since the DID spliced ​​display screen panel introduced to achieve a minimum 6.7 mm bilateral splicing seam. The remarkable improvement of the joint technology of LCD splicing products has significantly narrowed the gap between DLP and other products, and has also expanded the use of LCD products. LCD splicing products have entered the mainstream application market in an all-round way, and the market share has already turned upside down in 2009. The promotion of Fan. At present, the splicing gap caused by the bottleneck of liquid crystal splicing liquid crystal panel cutting technology is being significantly resolved due to technological progress. The mass production of Samsung LCD splicing products with a display unit with a thickness of only 3 mm is also on the agenda and is expected to be Officially launched in the second half of 2010. It is believed that the era of full application of Samsung LCD Video Wall will soon come!

Third, the color of high-definition high-definition, relatively low energy consumption In video surveillance, the camera provides a front-end capture screen, the monitor terminal will have to complete the output display of the back-end video images. When the camera is driven by the pursuit of high-definition waves and the quality of collection continues to increase, the development of monitors will surely usher in a revolution in high-definition so that high-definition images can be perfectly restored.

In terms of monitors and large-screen videowalls, DLP and LCD have always been difficult to distinguish. Each has its own unique advantages. In the future, this pattern may change rapidly.

It is understood that DLP in the stitching gap is relatively small, the display contrast is high, the unit size is more, but the DLP splicing wall volume and the occupied area is relatively large, high power consumption, long time work easily produce a phenomenon of reduced brightness. In this regard, despite the use of dust-free boxes on the market to reduce the intrusion of dust to prevent light from affecting the brightness, and using dual-lamp technology, two built-in light bulbs are designed to emit light at the same time, greatly improving the brightness of the screen. However, the energy consumption of DLP has also been further improved, which does not meet the demands of modern society for low energy consumption.

The splicing technology of the LCD liquid crystal splicing screen is to treat each unit as an independent splicing processing system and input a complete signal and control signal, which is processed by each unit independently, so as to ensure that the signal volume to be processed by each unit body is small and sufficient. Ensure the clarity of the image and the smoothness of the video. The 6.7mm ultra-narrow slit is an almost seamless category accepted by the human eye. What's more exciting is that the new 3mm product will soon be put into mass production, making it more conducive to the splicing of large screens and further improving the overall look of the screen.
