Organisations in the retail, leisure, entertainment, exhibition, hospitality and other sectors are discovering how state-of-the-art videowalls can deliver high-definition, high-impact images and video at any scale.

A videowall is a large screen surface comprising multiple LCD, plasma or DLP displays driven by a videowall controller.  Originally an array of closely-packed televisions or CRT monitors, the objective of the videowall has always been to make the system appear to be one large screen.  The problem, of course, was the large frame or bezel that surrounded each unit.

Today's videowalls use tiled LCD screens or rear-projection cubes, with ultra-narrow frames/bezels to minimise any dead pixel space between the individual units, and have custom-built vertical or horizontal mounting systems.

LCD videowalls typically achieve higher resolution than rear-projection systems, and have a much smaller footprint.  All videowalls retain their brightness irrespective of size, and some of today's systems can be used in high ambient light.
An LED screen is not technically a videowall as it is not made up of individual stand-alone units, although in the USA it is sometimes referred to as one.

Applications include control rooms, reception areas, meeting/conference rooms, shops/malls, exhibitions and public spaces.  Our advanced colour calibration and brightness settings mean crystal-clear, pin-sharp images – ensuring your message is delivered in style, with the highest possible impact.

Anyplace Media Group's LCD-based videowalls use 46, 49 and 55 inch panels.  While most videowalls are used to create one large image, they can also be used as programmable interactive displays and touchscreens, and have the added benefit of being able to display material from multiple sources.

Rear-projection videowalls

Utility providers, for example, rely on rear-projection videowalls for network monitoring.

These videowalls comprise a series of 'cubes' – each featuring a projector and screen.  The projectors are positioned at the base of the units and point upwards where a 45° mirror reflects the image on to the screen.  This arrangement dramatically reduces the depth of the cubes.

The benefits of rear-projection videowall technology include very small mullions between cubes, although they take up more space than LCDs.

Videowalls have these features in common...

  • They require videowall controllers to get content on to the screens – although some have controllers built-in.
  • They are flexible about the quantity of individual component screens used.
  • They require a calibration mechanism to ensure individual screens are set to the same brightness, contrast, etc.

The benefits of LCD videowalls include...

  • Pin-sharp images – higher resolution, brightness and contrast than other technologies
  • Small footprint
  • High impact – displays retain their brightness irrespective of size
  • Suitable for indoor and outdoor use – even in direct sunlight
  • Capable of displaying content from multiple sources
