With the rapid development of networking, large-scale network conferences will be used in major governments, enterprises and other fields. For example, conveying instructions from higher-level leadership departments, communication between corporate branches, etc. can be solved by using the conference large-screen display system. .

1. The effect achieved

Through a complete conference large-screen display system, it can achieve online network conference, high-definition display, simultaneous input of multiple computer signals, video conference, audio playback and other functions.

2. In addition to the space required to form this display system, the following equipment is also required

1. Display screen

Under normal circumstances, if it is a conference hall with hundreds of people participating, it usually uses LCD splicing screens, small-pitch LED displays, projections, etc., such as the government auditoriums that we often see on TV. This kind of display method has been gradually eliminated, the screen is limited, the contrast is low, the image often seen will be whitish, and it is not clear when displaying some text. Therefore, more conference centers currently choose functions such as networking and high-definition. Therefore, the current development direction is based on LCD splicing screens and small-pitch LED displays.

The small-pitch LED display is a refined product of LEDs. The resolution is increased by reducing the distance between the lamp and the lamp, so that the image can be displayed more clearly. This is also to solve the problem of low resolution of LEDs. Technology-based products launched. Although the smallest LED pitch can reach 0.88mm, the price is expensive, several times more than ordinary LCD, so if you want to build a large screen of 10 square meters, it will cost millions of dollars, which is undoubtedly a huge Investment, but if you use a product with a relatively large spacing, its resolution is too low, there will be different degrees of mosaic phenomenon during display, which seriously affects the visual experience.

The advantage of LCD splicing screen is obvious, and its application in conference large-screen display system is also common. Its single screen resolution can reach 1920*1080, and 4K display can be achieved after four pieces of splicing, and the brightness and contrast are very high. , The color display of the entire screen has reached the highest level at present, just like a home TV. Its only flaw is that there are stitching gaps of different sizes between the screens, the largest is 5.5mm, and the smallest is 0.88mm, so there will be an obstacle to the user's vision when displaying images.

2. Control equipment

Under normal circumstances, only one screen is displayed on the large conference screen. At this time, it only needs to be controlled by a distributor. But sometimes it will output the signals of multiple computers and display them in different areas. At this time, you need to use a matrix. For example, if there are 3 computer signal inputs and 12 large screens, you can use a 4 in 12 out HDMI High-definition matrix, so that each signal source can be arbitrarily switched to have a certain block or several adjacent blocks displayed on the screen.

In some large enterprises, there are often branches all over the country, and the video conferencing function is often used. At this time, it is necessary to purchase video conferencing software, and distribute videos in various regions through the host, so as to realize real-time video conferences in different places. Function of

3. Control the computer

Install large-screen software to control the input and output of various signals. It is the control host of the entire conference large-screen display system.

4. Sound

Under normal circumstances, whether it is an LCD splicing screen or an LED screen, there is no voice playback, so if you want to achieve video playback, you also need to connect an external speaker. This general display device has a BNC output interface and you can connect it directly.

5. Web conference camera

If you need the video conferencing function, you need to purchase this camera equipment separately, which can be directly connected to the large screen via USB.
