What is Video Wall

Video wall, as the name suggests, is a large-sized screen formed by splicing multiple screens together. These displays are contiguous or overlapping and are usually rectangular in shape.

Generally speaking, these large screens can be composed of several different screen materials. Currently, the most widely used are LCD video wall and LED video wall, in addition to Laser Phosphor Displays, and rear projection cubes.

Screens designed for video wall usually have narrow borders, which is to minimize the width of the gap in the middle of the screen splicing. At the same time, the post-maintenance is fully considered during construction. After installation, the screen can still be reassembled or the height and spacing of the screen can be adjusted as needed. In addition to hardware installation and assembly, you also need to pay attention to the power supply and the connection of video and control signals between screens. The screens are usually daisy-chained together, and a control signal can turn all screens on or off.

So, why use splicing screen, the reasons are as follows: First, the cost per unit area of ​​a single large-size screen is higher than that of a splicing screen. Moreover, the pixel density of the splicing screen is higher than that of a single large screen. The splicing screen can also be freely combined, and can be spliced into irregular shapes according to your own needs.

 

Video controllers are usually used to control video walls. Types of video controllers include:

 

Hardware-based controller: Typically used for a single purpose, similar to a remote control used for traditional TVs. Without their own operating system (OS), they are built using video processing chips with one or more inputs that split content across multiple displays. Because of their single purpose and lack of flexibility, they also have excellent performance.

 

Software-based controller: Requires a dedicated PC running an operating system or a server with a special graphics card. While offering greater flexibility, the ability to run and display applications directly on the video wall. Performance depends on the quality of the graphics card and management software.

 

video wall generally appear in large public places, such as high-rise buildings and commercial plazas with large traffic. The most famous one is the large splicing screen in Times Square. They also sometimes appear in corporate meeting rooms or control rooms and stadiums. Ideal for events with a large number of people, giving them enough resolution to view upcoming events.

What is the aspect ratio

  The aspect ratio describes how the picture appears on the screen. Take 4:3 as an example, 4 refers to the width and 3 refers to the height. To understand this question, we have to look back at history. The size of the first movie film used by Edison in the laboratory was 1 inch wide and 0.75 inches high. To avoid decimals, it became the most familiar 4:3 format, which lasted 60 years as the standard format for film production. Then came a watershed moment in American history: the television boom. For a while, the 4:3 aspect ratio of movies worked well with rectangular television screens, and seeing more and more households buying televisions, studios had to use the new format in an attempt to draw audiences away from home back to the theater.
