Looking at it from afar, with the progress of society and the improvement of the level of science and technology, the advertising release system around us is always constantly upgrading. Whether you are on the street or in a shopping mall, you can always see very gorgeous and dazzling video advertisements around you. Take a closer look at the original cool video advertisements that are stitched together one by one. Some large screens in Splicing City don’t look carefully, and they think it’s a whole piece of screen hanging on the wall or in the middle of the mall. There are a lot of introductions about splicing screens on the market, mainly because the scope of application of LCD splicing screens is very wide. All walks of life can use it as long as it involves display, and it can not only be used for TV screens. Broadcasting, screening, and splicing can also be used, which can meet the needs of different fields and different scenes, and the range of choices is very wide.
After undergoing the LED reform, LCD splicing screens are currently used for publicity. The structure of LCD is to place a liquid crystal cell between two parallel glass substrates. The lower substrate glass is equipped with TFT (thin film transistor), and the upper substrate glass is equipped with a color filter. The signal and voltage on the TFT are changed to control the liquid crystal molecules. Rotate the direction, so as to control whether the polarized light of each pixel point is emitted or not to achieve the purpose of display. The LCD consists of two glass plates with a thickness of about 1 mm, separated by a uniform interval of 5 mm containing liquid crystal material. Because the liquid crystal material itself does not emit light, there are lamp tubes as light sources on both sides of the display screen, and there is a backlight plate (or even light plate) and reflective film on the back of the liquid crystal display screen. The backlight plate is composed of fluorescent materials. Can emit light, its main function is to provide a uniform background light source. So, why are LCD splicing screens so popular, and what are the advantages?
1. Large viewing angle of LCD splicing screen
For the early liquid crystal products, the viewing angle was once a big problem that restricted the liquid crystal, but with the continuous advancement of liquid crystal technology, this problem has been completely solved. The DID LCD screen used in the LCD splicing curtain wall has a viewing angle of more than 178 degrees, which has reached the effect of absolute viewing angle.
2. Long life and low maintenance cost
Liquid crystal is currently the most stable and reliable display device. Due to the small heat generation, the device is very stable and will not cause failure due to excessive temperature rise of the components.
3. the resolution is high, the picture is bright and beautiful
The dot pitch of the liquid crystal is much smaller than that of the plasma, and the physical resolution can easily reach and exceed the high-definition standard. The brightness and contrast of the liquid crystal are high, the colors are bright and bright, the pure plane display is completely free of curvature, and the image is stable and does not flicker.
4.low heat generation, fast heat dissipation, and low power consumption
Liquid crystal display equipment, low power, low heat has always been praised by people. The power of a small-size LCD screen is not more than 35W, and the power of a 40-inch LCD screen is only about 150W, which is only about one-third to one-fourth of that of plasma.
5. Ultra-thin and lightweight, easy to carry
The liquid crystal has the characteristics of thin thickness and light weight, which can be easily spliced and installed. The 40-inch dedicated LCD screen weighs only 12.5KG and has a thickness of less than 10 cm, which is unmatched by other display devices.
6.the openness and scalability of the system
Digital network ultra-narrow-edge intelligent LCD splicing system follows the principle of open system. In addition to direct access to VGA, RGB, and video signals, the system should also be able to access network signals, broadband voice, etc., and can switch various signals at any time And dynamic comprehensive display, to provide users with an interactive platform, and support secondary development; the system should have the ability to add new equipment and new functions, making hardware expansion very simple. At the same time, the software only needs to be expanded and upgraded to meet the requirements without modifying the source program. The hardware and software parts of the system can easily “advance with the times”.
Application places of LCD splicing:
1. Information display terminal for transportation industries such as airports, ports, docks, subways, highways, etc.
2. Financial and securities information display terminal
3. Display terminals for commerce, media advertising, product display, etc.
4. Education and training/multimedia video conference system
5. Dispatch and control room
6. Emergency command system of military, government, city, etc.
7. Mining and energy security monitoring system
8. Command system for fire control, meteorology, maritime affairs, flood control, and transportation hub
