The South China General Manager of the Samsung Business Monitor Guangzhou Guangrun large-screen display system has been widely used in telecommunications network management, command, traffic monitoring and management, military combat command training, industrial production scheduling and other areas of the control room has been widely used, it can The signals from various signal sources such as RGB, Video, and network are displayed in a centralized manner to meet the needs of users to display various shared information and comprehensive information in a large area. The common large-screen video wall system is usually divided into three main types according to the working mode of the display unit, that is, the LCD display unit splicing the video wall, the PDP display unit splicing the video wall and the DLP rear projection display unit splicing. Among them, the former two belong to a flat panel display unit splicing system, and the latter belongs to a projection unit splicing system.
Plasma large-screen splicing video wall system
PDP (PlasmaDisplayPanel), namely plasma display. The PDP is a display technology that utilizes gas discharge. Its working principle is very similar to that of a fluorescent lamp. It uses a plasma tube as a light-emitting element. Each plasma tube on the screen corresponds to a pixel. The screen uses glass as a substrate, and the substrates are spaced a certain distance to form a discharge space. The discharge space is filled with inert gas such as helium, neon and the like as a working medium. On the inner surfaces of the two glass substrates, a metal oxide conductive film is coated as an excitation electrode. When a voltage is applied to the electrode, a plasma discharge phenomenon occurs in the gas mixture in the discharge space, which is also called a plasma effect. The plasma discharge generates ultraviolet rays, and the ultraviolet ray excites a fluorescent screen coated with red, green and blue phosphors, and the fluorescent screen emits visible light to show an image.
The PDP unit splicing the TV wall has the advantages of bright colors, high contrast, and high brightness, but also has its own insurmountable disadvantages. Because plasma consumes a lot of power and heat, it can cause serious burns and is not suitable for long-term static screen display monitoring. And after the PDP unit is used for splicing, the temperature of the whole machine is higher, so that the device is easily burned. In addition, the price of plasma splicing video walls in the market is relatively high, and the price of one square meter is generally more than 100,000. Today, low-carbon and energy-saving have become the mainstream trend. For most ordinary users, the plasma-spliced ​​TV wall is obviously not the best choice.
Despite its many shortcomings, the bright plasma and high-brightness features make it possible to display images with outstanding advantages, making plasma splicing the darling of some exhibitions. In addition, the government agencies that require higher picture quality are also preferred. However, plasma splicing video walls are completely disadvantaged in terms of overall market share, and the development potential of plasma splicing video walls is limited in terms of the development trend of the entire industry. According to some industry analysts, the industry is currently a “chicken industry†and it will certainly be replaced in the future.
LCD LCD TV Wall
The so-called LCD LCD large-screen splicing is a splicing screen body that adopts the LCD display unit splicing method and achieves a large-screen display effect through a splicing control software system. LCD LCD splicing is currently represented by South Korea's Samsung DID. Although there are SHARP, LG, NEC and other brands in the splicing market, DID is unique in LCD panel splicing technology with its excellent price/performance ratio.
The LCD splicing TV wall has the advantages of thin thickness, light weight, low energy consumption, long life, no radiation, etc., and its fine picture, high resolution, and excellent performance of various key performance indicators have made it a mainstream of development and a promising prospect. As a spliced ​​video wall display terminal, despite these advantages, LCDs, as spliced ​​video wall display units, have disadvantages that are fatal: that is, they are currently taught in large numbers and are the largest among the three spliced ​​TV wall display units. Users have to give up and give up.
Then, the rear projection, plasma and liquid crystal have more technical advantages, and can better meet the needs of various applications? We believe that LCD will be able to better meet application requirements. This is exactly what this article will explain to you. We will list the technical principles of rear projection, plasma and LCD display modes, and analyze several key indicators. Their respective advantages and disadvantages, as well as the advantages of Youan LCD splicing curtain wall.

Collated Nails
Common Nails designed with collated paper strip are mostly used as framing nails and Roofing Nails. It is made for quick uses and high efficiency works on the decking or flooring constructions. Normally the wire nails are hot dipped galvanized, or copper plated to enhance the corrosion resistance and beautiful outlook. The collating angles of the nails can be different while now mainly supplies four types: 34 degree, 28, 21, 17 degrees.
