Nowadays, video wall technologies for various conference rooms emerge in an endless stream, and all major display technologies have launched their own solutions. Due to the disadvantages of small screen and poor display effect, the previous projection display is gradually being eliminated, and more high-definition, high-contrast, and splicable display technologies are more and more favored by users. At present, LCD Display, LED video walls and Interactive Flat Panels are mainly used in conference rooms.
LCD Display:
LCD display screen is a commonly used conference room display solution at present. It is a large screen formed by splicing multiple LCD screens. It has a series of display features such as high-definition and high contrast, and its brightness is more suitable. Indoor use, no glare or reflection. If we are using it in some small and medium-sized conference rooms, the viewing distance is relatively short, and the pictures on the computer, web pages, and video conference displays are mainly played, then the LCD Display screen is a very suitable display screen solution for the conference room.
Advantage:
- High definition, splicing can reach 4K display, and the picture is not blurred;
- The brightness is about the same as that of TV, and the screen is not dazzling when watched for a long time;
- High contrast, good picture quality;
- The screen is stable, and there is basically no after-sales service if there is no external force collision.
Disadvantages:
There is a seam, and there is a border at the splicing of the screen, which has a slight impact on full-screen display.
LED video wall:
LED video wall is also a commonly used conference room display solution, but due to its characteristics, it is mostly used in some large conference rooms, such as conference rooms with many participants and long viewing distances.
Advantage:
There is no seam effect, the entire screen does not have the frame effect like LCD Display after splicing, so the overall quality is better.
Disadvantages:
- The clarity is average, and it will be better only with some small-pitch LED, but the overall resolution cannot reach the resolution of LCD;
- It is easy to die the light, and the LED lamp beads will lose the light. These will cause some pixels to not emit light or only emit monochromatic light, which will affect viewing.
Interactive Flat Panel:
Interactive Flat Panel is a large-sized tablet computer. Its size can reach about 100 inches, and it supports touch. It has a built-in computer system, which can be used as a separate computer. It is very functional. , which is also a commonly used meeting room display solution in small meeting rooms.
Advantage:
- The display effect is good, and the brightness and contrast continue the advantages of LCD liquid crystal display;
- Can be touched by fingers, as easy as operating a smartphone;
- 4K high-definition, ultra-high-definition display can be achieved without splicing;
Conference room display system can be divided into three parts:
Display terminal (video wall)
Signal processing system (Matrix Switcher, video wall controller, etc.)
Control terminal (computer, notebook, etc.)
In an ordinary conference room, generally only one large screen image needs to be displayed. Therefore, the digital matrix is not used, and multiple inputs and outputs are not needed. Only a video distributor is needed to connect the screens in series and parallel to complete the corresponding functions, demonstrations, and operations;
The digital matrix is generally used with a splicing processor when multiple There are more monitoring centers displayed on the road.
The control terminal is generally controlled by a computer, tablet or mobile phone. If you want to display a higher resolution, you need a high-configuration control terminal.
Features:
Versatility and customization: Video walls have the advantage of versatility and customization. They can be custom configured to suit meeting rooms of different sizes and shapes. The video wall supports multiple signal inputs, such as HDMI, VGA, DVI, etc., and can be connected with various devices and systems. In addition, the video wall also supports multiple resolutions and display modes, which can be flexibly configured according to different application scenarios.
Reliability and maintainability: Video walls are generally highly reliable and maintainable. Since the video wall is composed of multiple modules, when one module fails, only that module needs to be replaced instead of the entire screen. This greatly reduces maintenance costs and downtimes and guarantees system availability.
In the conference room display solution, video wall products form a large picture by combining multiple display screens. With high-definition, bright colors, detailed pictures and other display features, the conference content can be displayed more intuitively. Effectively improve work efficiency, improve the efficiency and participation of meetings.
