Basic knowledge and cognition of LCD stitching screen
With the continuous progress of society, people need high -definition screens that people need to reach in various fields, and LCD splicing screens are a large screen display product that has emerged in recent years. In recent years In various fields, a large screen is composed of multiple stitching units, giving a good visual experience, a natural and realistic picture effect. Next, let's understand the LCD splicing screen and understand some of its basic knowledge.
1. What is LCD stitching screen
The LCD LCD stitching screen is the abbreviation of LiquidCrystalDisplay. The structure of the LCD is placed in the two parallel glass. There are many vertical and horizontal small wires in the middle of the two glass. In the direction, reflect the light to generate the picture. LCD is composed of two glass plates, about one millimeter thick, and is separated by five microns containing liquid crystal materials. Because the LCD material itself is not glowing, there is a lamp tube on both sides of the display, and there is a backlight plate and reflective film on the back of the LCD display. The backlight is composed of fluorescence. It mainly provides a uniform background light source. The light emitted by the backlight board enters the LCD layer containing thousands of liquid crystal droplets after passing through the first partial polarizing filter layer.
Second, the screen composition of the LCD stitching screen
The liquid droplets in the LCD layer are included in a small cell structure, and one or more cells form a pixel on the screen. There is a transparent electrode between the glass plate and the liquid crystal material. The electrode is divided into lines and columns. At the intersection of lines and columns, the liquid crystal lighting state is changed by changing the voltage. valve. With the continuous progress of society, people need high -definition screens that people need in various fields, and the LCD stitching screen has been a large screen display product that has emerged in recent years. In recent years In various fields, a large screen is composed of multiple stitching units, giving a good visual experience, a natural and realistic picture effect. Today I will take you to understand the LCD splicing screen and understand some of its basic knowledge.
Third, parameters of LCD stitching screens
Around the liquid crystal material, the control circuit part and the drive circuit part, when the electrode in the LCD generates an electric field, the liquid crystal molecule will be distorted, which will reflect the light through the light in it, and then pass the filter of the second layer of filter layer. Show on the screen. LCD stitching (LCD splicing) is a new splicing technology that has emerged in recent years after DLP stitching and PDP stitching. The LCD LCD splicing screen has the advantages of low power consumption, light weight, long life, no radiation, uniform screen brightness, etc. ; Now that you can eliminate the gap between the splicing screen through special technologies, or achieve the smallest seam 0.88mm
At present, the stitching screen size is 46 inches, 49 inches, and 55 inches in LCD LCD splicing. It can be spliced arbitrarily according to customer needs, infinite stitching, and uses backlight sources, with a lifetime of 60,000 hours. Secondly, the point distance of the LCD can be easily met with the high -definition standards; in addition, the LCD screen consumption is small, the heat is low, and its power is only about 150W. Low.
Fourth, splicing screen installation method
The installation method of common stitching screens is embedded, pre -maintenance of wall -mounted hydraulic, cabinet -type installation, landing bracket installation; the installation of the LCD stitching screen can be designed according to the actual environment of the installation site and the fixed support structure. Demand design pre -design or post -maintained screen structure.
5. LCD splicing screen application field
At present, the LCD splicing screen is obtained in all walks of life. Most of them are used at airports, ports, docks, subways, highways, exhibition halls, monitoring command dispatch centers, shopping mall store propaganda, corporate government unit conference room, traffic command terminal display, display of traffic command terminals, display of traffic command terminals, display of traffic command terminals, display of traffic command, display terminal display, display of traffic command, display of traffic command, display terminal display, display, and display of traffic command. Classroom intelligent display, scheduling, control rooms, radio and television, large -scale studio/performance halls, military, government, cities and other emergency command systems and other indoor places.
The above is some basic knowledge about the stitching screen. I hope it will be helpful to you in the process of understanding the LCD stitching screen. If you have any questions, please consult and communicate.
