DLP Rear Projection Steady Development in Command and Control Room Applications

In recent years, large-scale LCD flat panel display technologies have been officially launched and developed rapidly. In the control room area, many users have also switched from using wall-mounted panels to using flat panel displays. However, the rise of LCD does not mean the end of the first DLP wall, because in 7×24 applications, the rear projection box is more cost-effective than other technologies, especially after the LED light source has been widely adopted.

After nearly three years of improvement in technology and products, the LED light source DLP display system has now entered a stage of stability and maturity. The major global DLP rear projection movement manufacturers without exception have introduced their own LED light source products, such as Mitsubishi Mitsubishi, Barco, Christie, Planar, including domestic giants such as GQY, Viagra, LED light source rear projection products compared to the original The brightness of LED light source products should be more than doubled, and even exceed the brightness of traditional UHP light sources, so that the system color is improved, especially the service life is greatly extended, and the application of LED light sources in more complicated environments is greatly expanded, such as the command room. And control room.

In a modern, intelligent control and management center, operators have to face a variety of complicated information, and a large amount of information input needs to be received, displayed, analyzed, and stored. At this time, the large-screen display wall has become a collection of various information, and the only means to present it in front of the operator in an intuitive and visual manner has become the focus of all operational operations, and projection is a versatile and flexible tool. Technology, first of all, rear projection splicing products have better color performance, which is reflected in the accurate reproduction of color, so it is more suitable for application in the control room, and the color of plasma and LCD products is too bright, more eye-catching , but it is not as good as the rear projection product in terms of true color.

Secondly, there are many kinds of products in the large-screen splicing market. The medium and small sized products mainly include liquid crystal and plasma products. The large-size seamless splicing is mainly the rear-projection splicing technology. From the perspective of size, rear projection splicing has 50-inch, 60-inch, 67-inch, 80-inch, and 100-inch products, with the advantage of oversized.

From the perspective of applications, rear projection splicing products can support 24-hour work, and can achieve ultra-large-scale splicing. The spliced ​​interface is equipped with a built-in image processor, and has a rich interface and can display richer screen content. In addition, the biggest advantage of rear projection is that it can achieve seamless splicing technology, and the splicing gap is only a few tenths of a millimeter. Although the LCD splicing technology has already launched 5.3mm ultra-narrow seams, it will still be visible to the naked eye. A very obvious black line.

The LED light source rear projection splicing products, so that the cost of light bulbs showed a downward trend, in terms of service life, can reach 60,000 to 80,000 hours, and the life of LCD splicing products is the same, to make up for the lack of front projection splicing products At the same time, the projection era is also concerned that many manufacturers are actively promoting the commercialization of laser rear projection. In terms of volume and thickness, Mitsubishi also launched a front maintenance rear projection splicing product. The overall thickness has been greatly reduced, which is much thinner than that of common rear projection splicing products, and has also solved some environmental requirements.

In addition, the potential of DLP rear projection is also inestimable. Christie's MicroTiles is the most DLP splicer in the industry's design. This compact size (400 × 300 × 260mm) display device opens up the display device artistically. New opportunities for application. The device can be combined together to seamlessly stitch out any size and format of the image, and the screen resolution is higher than the LED display device and LCD display, each screen resolution of 720 × 540, so that the application of DLP rear projection becomes Be more flexible. So, while companies such as Pioneer and Sony have already reduced the development of the video wall market, many companies such as Mitsubishi, GQY, Victron, Barco, Christie, Planar, and Lanbo still stick in these control rooms. The market for applications continues to develop higher resolution, more reliable box products.

T Nuts are an economical method of fastening a metal mechanism to a component that is made of wood, plastic, particleboard,  pressboard or for anchoring wooden components to each other . The row material is carbon steel or stainless steel (304/316). 

Surface treatment:Zinc plated,plain,black

4 Prong T Nuts can be used in hard and soft woods.
