Diversified competition in the large-screen splicing market, HD may become a key point

In the face of large-scale high-definition signal sources, the traditional monitor TV wall display has become powerless. As the monitoring system moves toward large-scale and high-definition, the display terminal, which is one of the important components of the system, has also developed rapidly, among which large-screen LCD splicing walls are the most popular.　　 High-definition may not necessarily choose a large screen, but the large screen has its own unique value. The large-screen splicing wall not only has a complete picture, but also has a good demonstration effect. In the fields of energy, public safety, transportation and other fields of video surveillance, command and dispatch, and public information display, it has a centralized display of multiple screens. Features, will effectively improve monitoring and emergency response efficiency. It can not only be used as the display carrier of high-definition video signal source in the monitoring center, but also can realize multi-service, multi-input fusion display, remote release of video and image by relying on the multi-screen processor, which is convenient for managers to better display in one display interface. Calling multi-party resources, comprehensive analysis, and quick decision-making. Therefore, large-screen splicing walls have sufficient market space in the future, and their position in the security industry will increase day by day.　　 At present, all companies that are making large-screen splicing walls are developing in the direction of high-definition, and high-definition will be the focus of the future. For a relatively long period of time, the large-screen splicing wall market has shown a three-pronged situation. The three display technologies of DLP, PDP, and LCD have occupied different market shares by virtue of their respective advantages. product.　　 DLP splicing products using UHP bulbs are gradually being replaced by DLP splicing products using new LED light sources. LED light source splicing walls are fully promoted by DLP manufacturers, which to a certain extent alleviates the impact of flat panel splicing on the rear projection splicing market. In terms of flat panel splicing, PDP has launched the latest MPDP screen with ultra-thin, 60-inch, 3mm splicing walls, which injects new elements into the shrinking PDP market. LCD splicing screen manufacturers not only have to compete for the market with DLP and PDP splicing manufacturers, but also face competition from LCD peers. Therefore, major manufacturers continue to introduce new products to the market. 47-inch, 55-inch, 60-inch and other multi-unit LCD splicing products are all effective weapons used by LCD splicing manufacturers to compete with DLP large-size splicing products for the market.　　 Although the first two continue to improve in technology, under the high-definition trend, there are still unavoidable challenges. Although DLP splicing products have the advantages of large single screen size and small seams, they also have defects such as low color saturation, uneven brightness, excessive product power consumption, and large space occupation. The larger the size, the defects are exposed. The more it is, the more it is limited by its own display principle, it mainly relies on the image processing function of the splicing processor to make up for the shortcomings in dealing with high-definition. Although PDP splicing products have excellent dynamic display effects, they have defects such as static display, easy to burn the screen, easy to produce afterimages, easy to fade in brightness, short service life, and high maintenance costs. It is slightly inferior to LCD splicing products in terms of handling high-definition.　　In contrast, LCD splicing products have comprehensive advantages such as flexible and vivid pictures, high resolution, long life, high brightness, high definition, and low cost. It uses industrial control or pure hardware embedded splicing technology to input a complete signal, and each unit can be used as an independent splicing processing system, thus ensuring the clarity of the image and the smoothness of the video. The high-definition display and technical processing of the LCD splicing wall are concentrated on the LCD splicing processor. The LCD splicing processor has high-end image processing functions such as high-definition video signal acquisition, real-time high-resolution digital image processing, and three-dimensional high-order digital filtering. Has powerful processing capabilities.
