LCD splicing screen
The main indicators of LCD splicing screen are as follows
Size: such as 46 inches, 49 inches, 55 inches, 60 inches, etc.
Brightness: for example, 450cd
500cd
700cd
㎡ and so on.
Comparison: for example, 3000: 1, 3500: 1, 4500: 1 and so on.
Flat seam: for example, 22mm, 10mm, 6.7mm, 5.5mm, 4.9mm, 3.5mm, etc. But at present, Samsung has made a flat seam of1.7mm.
Splicing processor: divided into built-in (few interfaces, simple functions) and external (many interfaces, extensible, rich functions).
There are four main uses of splicing screen: command and dispatch, video monitoring, video conference and information release. Command and dispatch are generally used in public security and military systems, video surveillance is used in safe cities, and in the construction of smart cities, it is often used in transportation systems. Video conferencing is mainly used in government systems and large group companies. Information release is mainly used for large shopping malls, exhibitions, etc. In addition, many entertainment places like bars and ktv can use LCD to splice large screens.
Generally, the splicing screen is only used as a display unit, which can display a fraction of the signal of a picture. If there is no matrix or distributor, a mosaic screen can only display one picture, which is fixed. Unless the signal source is changed, the matrix can access the signal through the matrix, and then the control matrix can randomly mobilize any display screen to display any signal to achieve the display control effect.
Large screen splicing
The control equipment arranged in the middle of the LCD splicing screen varies according to the purpose and effect. The total production cost of LCD splicing screen manufacturers is several pieces, one is the screen body, the other is the intermediate control equipment, the third is the installation of brackets and wires, and the fourth is the installation fee and freight. So first determine whether to use 46-inch or 55-inch splicing, then confirm whether there is a signal or video on the screen or display effect, and then determine whether the customer's wall is weighed. In this way, we can determine what kind of installation method you use, the size you have determined is 10 square, and the height and width of the screen body are also determined, so that we can determine whether to use 46-inch blocks or 55 blocks for projects and projects.
