1 Splicing screen
At present, there are many kinds of display screens on the market. Based on years of design experience, it is concluded that the types of splicing screens that are applicable and commonly used in monitoring halls are LCD splicing screens, DLP rear projection splicing screens, LPD laser splicing screens and LED splicing screens. , They are different in technical parameters, display methods, and unit specifications. Products of the same brand have great differences between different series.
With the continuous development and improvement of science and technology, video display equipment from LCD display modules, DLP rear projection splicing display units, LED LCD splicing screens, to LPD laser splicing screens, OLED splicing modules, more and more new products and new technologies , Diversified display equipment came into being. The popularity of networking and data has also led to the birth of a large number of monitoring halls. In recent years, some domestic communication companies, financial companies, governments, transportation, safety supervision and other enterprises and institutions have successively built data centers and monitoring halls. To some extent, it has also promoted the development of splicing screen technology and market expansion. This article summarizes four different types of splicing screens, and the application of these splicing screens in the monitoring hall.
The splicing screen is composed of several separate screens or modules. For example, the DLP rear-projection splicing screen is a single box (with a projector installed in the box), while the LED splicing screen is formed by splicing modules of different specifications and sizes. The splicing screen can display video pictures on a single screen, or several single screens can be spliced into a super large screen according to the use needs and room size; it can display a single or multiple pictures, or a single screen can split to display several pictures, and the display methods are convenient and diverse And the installation is simple, it is widely used in the monitoring hall.
2 Monitoring hall
The monitoring hall is also called the monitoring center. Its English is "Enterprises Control Center", which translates as "Enterprise Control Center", or ECC for short. Many domestic enterprises also call the network monitoring hall or monitoring center of the data center ECC.
The monitoring hall is where the staff of the enterprise or unit need to synchronize and monitor network data and online application services in real time 724h, and provide timely and efficient solutions to emergency and emergencies. At the same time, the monitoring hall is also the nerve center and exhibition center for maintaining the quality of customer experience.
3 Types of splicing screens
3.1 LCD splicing screen
LCD is the abbreviation of "Liquid Crystal Display", which translates to "liquid crystal display". Its imaging principle is that a layer of liquid crystal is sandwiched between two soda-free glasses. Using the electro-optical effect of the liquid crystal, the current stimulates the liquid crystal molecules to produce point, line and surface coordination. The back light tube constitutes the picture.
The LCD splicing screen is composed of a single LCD panel of different sizes. The picture quality and viewing effect directly depend on the panel technology. Therefore, when choosing an LCD splicing screen, it is important to filter the type of panel, such as brightness, color, viewing angle, and contrast. Both are important parameters of LCD splicing screen panels. Screen panels are usually divided into soft screens and hard screens. Table 1 is a summary of screen technologies.
