Basic knowledge and cognition of LCD splicing screens
文章來源：華云視界 發(fā)表時間：2024-02-22With the continuous progress and development of society, people need high-definition large screens in various fields. As a new type of large screen display product that has emerged in recent years, LCD splicing screens have been widely used in various fields. They are composed of multiple splicing units, providing a good visual experience and natural and realistic visual effects. Today, I will introduce you to LCD splicing screens and learn some basic knowledge about them.
1、 The concept of LCD splicing screen
LCD splicing screen is a single independent and complete display unit that can be hung and used immediately. Installation is as simple as building blocks, and the use and installation of single or multiple LCD splicing screens are very simple. The edges of the LCD splicing are only available in various sizes such as 3.5mm, 1.7mm, 0.88mm, etc. The surface is also equipped with tempered glass protection layer, built-in intelligent temperature control alarm circuit, and unique heat dissipation system. There is everything, not only suitable for digital signal input, but also very unique support for analog signals. In addition, there are many LCD splicing signal interfaces, and DID LCD splicing technology is used to achieve simultaneous access of analog and digital signals. The latest LCD splicing technology can also achieve naked eye 3D intelligent effects. The LCD splicing series products adopt unique and cutting-edge digital processing technology, allowing users to truly experience the full HD large screen effect.
2、 Screen composition of LCD splicing screen
The droplets in the liquid crystal layer are contained within a small cell structure, with one or more cells forming a pixel on the screen. Between the glass plate and the liquid crystal material is a transparent electrode, which is divided into rows and columns. At the intersection of rows and columns, the rotation state of the liquid crystal is changed by changing the voltage. The function of the liquid crystal material is similar to that of small light valves. With the continuous progress and development of society, people need high-definition large screens in various fields. As a new type of large screen display product that has emerged in recent years, LCD splicing screens have been widely used in various fields. They are composed of multiple splicing units, providing a good visual experience and natural and realistic visual effects. Today, we will introduce you to LCD splicing screens and understand some basic knowledge about them.
3、 Characteristics of LCD splicing screen technology
1. Adopting straight down LED light source display technology, with a contrast ratio of 3000-4000:1; A color temperature of 10000K; Specially designed for video display, with high brightness and clarity, it still displays perfectly even in sunlight;
2. With exclusive dedicated graphics processors and matrices, it can support up to 256 screen walls;
3. The ultra narrow stitching can be as narrow as 0.88mm and has a border compensation function, which can highly restore the real picture;
4. High resolution, each display unit resolution can reach 1920X1080 and 4K;
5. There are various splicing methods, which can be placed horizontally or vertically;
6. The outdoor unit also has an "automatic diagnosis" function, which can determine the internal temperature and start the fan to cool down or heat up internally;
7. Long service life, stable operation, no burns or damage, low maintenance cost;
8. Rich input and output interfaces, VGA, HDMI, AV interface terminals, can connect to computers and various video devices;
9. It can connect to the network to achieve the transmission and playback of media files on the network (optional), and can choose to have a built-in high-definition media player;
10. The brand new "ultra wide angle extension technology" (LED backlight) ensures that images viewed from a 178 degree angle up, down, left, and right are not distorted, and colors are not distorted.
4、 Types of LCD splicing screens
1. Divided by gap: splicing screens with different gaps such as 0.88, 1.7mm, 1.8mm, 3.5mm, 0mm, etc;
2. Classified by brightness: high brightness splicing screen, low brightness splicing screen;
3. Classified by technology: OLED splicing screen, no color difference splicing screen, seamless splicing screen;
4. Classified by size: 55 inches, 65 inches, 70 inches, 75 inches, 49 inches, 46 inches, 43 inches, etc;
5. Classified by installation method: wall mounted, floor mounted, cabinet, front maintenance, curved, suspended, etc;
6. Divided by usage area: exhibition, conference, commercial, monitoring, data, etc. splicing screens;
7. Classified by panel brand: Samsung, LG, Huaxing Optoelectronics, BOE, Qunchuang, etc;
The above 7 different categories basically include commonly used ones in the market
5、 LCD splicing screen application field
LCD splicing screens are widely used in various industries, mostly in airports, ports, docks, subways, highways, exhibition halls, monitoring and command dispatch centers, shopping mall stores for publicity, corporate and government unit conference rooms, traffic command terminal displays, classroom intelligent displays, dispatch and control rooms, broadcasting and television, large-scale broadcasting/performance venues, military, government, urban emergency command systems and other indoor places.
