Video Wall: LCD or LED?

More and more commercial establishments (restaurants, businesses, entertainment venues and fairs) are using Digital Signage panels with multi-display configurations simultaneously, displaying various information on each screen/panel.

Our WorldVDS Digital Signage software offers the power of establishing zones of content to be displayed individually on each screen, or to use a video wall (composed of several screens) as if it were only one screen.

It should b remembered that, the simultaneous processing of videos on multiple high-resolution screens (a video wall that behaves like a single video wall display) requires a powerful processing system and computing power. The World VDS has been specially designed to deliver this outstanding performance and still provide extensive system flexibility and interactivity. This supreme quality performance is not possible with the vast majority of other existing solutions on the market. This is because they are much simpler alternatives.

Professional displays tend to be compact, lightweight and energy efficient. This provides optimum image quality that can be viewed from any distance or angle without distortion of color or image. In this way, video wall solutions are much more powerful than projectors, because the screen surface can be expanded without sacrificing image quality.

Whether for artistic reasons, to enhance the ambience of your business space, provide branding information, product or marketing data to your customers (visitors or employees), video walls are a great way to create a positive impact on a space and draw everyone's attention to whatever information or image you wish to display.

Video walls can be LCD walls or LED walls, each with slightly different characteristics.

Here are some of the benefits of incorporating a video wall into a digital signage solution:

• High Pixel Density: Because video walls have a high pixel density, they can display high-quality images and videos with excellent clarity and detail. This is particularly useful for applications requiring a large amount of visual data , such as surveillance, command and control centers, and digital signage;

• Flexibility: Video walls are extremely adaptable in terms of layout, size, and orientation. As a result, they can be used in a variety of applications and environments, such as control rooms, boardrooms, lobbies or retail spaces;

• Performance and dependability: Using a video wall controller can provide high performance and dependability, which is especially important in critical environments like command and control rooms. Though, this may come at a higher cost and with less flexibility;

• Communication: Video walls are an efficient way to convey information and data to a large group of people. This includes both internal and external communication, as well as making a good first impression on customers and visitors;

• Robust Reliability: When deployed in critical environments, video walls must always provide continuous and robust reliability, so that both the displays and the controller and its content manager do not need to completely deactivate the system at any time, including maintenance or part replacement;

• Design: Video walls provide a high level of design flexibility in terms of physical footprint, ease of installation, image quality, ambient light tolerance, ease of maintenance, and cost. As a result, they are appropriate for a wide range of applications and environments.

Here is a brief comparison of LCD video walls and LED video walls:

• LCD stands for Liquid Crystal Display, while LED stands for Light Emitting Diode. LCD uses liquid crystals to create images, while LED uses light-emitting diodes as a backlight source;

• LCD video walls are made up of multiple LCD panels with thin bezels that are mounted together to form a large display surface. LED video walls are made up of modules of LEDs that can be tiled together to form a seamless display surface;

• LCD video walls have better viewing angles and less glare than LED video walls. They also tend to be lighter in weight and more energy efficient. However, they have a size limitation and may suffer from image retention or burn-in over time;

• LED video walls have higher brightness and contrast than LCD video walls. They also have no bezels and can be scaled to any size or shape. However, they tend to be more expensive and heavier than LCD video walls. They also require more maintenance and calibration to ensure color uniformity.
