At present, in some multimedia conference rooms, in order to obtain high-definition and large-area display effect, LCD splicing screen can be selected to replace the original projection. Because we all know that the resolution of LCD screen can reach above 1920*1080, and it can realize 4K display function, so we can display high-definition movie sources and get high-definition display, which is very good for the viewing experience of indoor conference rooms.

First, LCD splicing screen

It is an important part of the whole display system to splicing different LCD screens into any size display area. The appropriate display area should be designed according to the length, width and viewing requirements of the background wall of the conference room. Moreover, according to this display area, the number of screen patches to be used is determined. The length of a 55-inch screen is more than 20 cm wider than that of a 46-inch screen, so it is different to use screens of different sizes.

After selecting the size and number of LCD splicing screens, which seam should be used in consideration of the overall display effect. Because the width of the seam determines the display effect of the whole mosaic. The smaller the seam, the smaller the black edge in the middle of the screen, and the better the natural display effect. At present, the mainstream Pinduoduo sold in the market is mainly 3.5mm, 1.8mm and 1.8mm..

Finally, we also need to consider how to install a large LCD screen to connect the screen. Because we are in the conference room, we should take up as little space as possible and be as beautiful as possible. For a solid wall, it can be directly attached to the wall to reduce the occupied space. If the number exceeds 9, it is recommended to maintain the brackets before installation for later maintenance. In this way, if there is a problem with the middle screen, there is no need to delete the surrounding screens. Also, if the background wall is not a solid wall, you can weld the bracket from the roof to the floor, hang the screen, and release the force point on the floor to reduce the pressure on the wall. Similarly, if the number exceeds 6, it is recommended to maintain it before use. After installing the screen in the future, you can wrap it around the screen, or you can use sound-absorbing boards or aluminum panels to wrap the edges around the screen. However, when decorating, you must keep a proper distance from the edge of the screen according to the requirements of technicians to avoid hitting the edge of the screen. If you touch the screen, you can prevent the screen from being damaged.

Second, the signal source and control equipment

Generally speaking, the signal source of LCD splicing screen in conference room is a computer, but in some cases only one computer is needed for input, but in some conference rooms, multiple computers are needed for input. If there is only one computer signal input, we can be with a LCD splicing screen distributor. This can achieve full-screen display effect. We only need to connect the computer to the distributor through the network cable, and connect the distributor to the LCD screen on the HDMI high listening cable. If there are multiple computer signals, you can use the matrix to switch and distribute the signals. For example, four computers need to be displayed on the screen, but there are 12 large screens in total. At this time, only 4 to 12 HDMI matrices are needed. The above two cases are common applications, but in some special cases, users need to display not only computer signals, but also multiple LCD splicing screen monitoring signals at the same time, and also screen crossing, roaming display and other functions. This includes decoder installation, external patch processor, etc.

In addition, in addition to the general LCD splicing screen computer signal, it needs to be used with video conference display in some cases. For example, an enterprise has several branches all over the country, and sometimes it needs to hold a remote video conference. We can install video conference software and webcam, and display the videos of several branches on the screen at the same time.

Basically, the LCD splicing screen LCD large screen split display system in the conference room is several types of large screen, signal source and control equipment. For other functions, corresponding software and hardware can be used in combination, such as video conference, touch function and audio. These functions can be individually configured according to specific needs.
