Video Display Walls – Is LCD or LED the right choice for you?
Cost is a consideration, but also a number of other factors come into play when choosing the right solution.

So first things first, not everyone know what the difference is between LCD and LED screens, so here’s a simple explanation.

The Science Bit

You probably use an LCD screen every day, you could even be reading this blog on it now…your mobile phone. LCD stands for Liquid Crystal Display. It’s basically a sandwich of polarised glass with a liquid crystal filling which flows just like a liquid, but has molecules that can be oriented like crystals. Apply electric current to those crystals, they move and let light through which creates the image. Clever!

LED, short for Light Emitting Diodes works in a completely different way. Hundreds of tiny LEDs are mounted onto a panel. Each one is like a tiny light bulb which gives off a coloured light when a particular voltage is applied to it. Clusters of these are used in red, green and blue which in turn create the full colour pixels required to produce an image.

Display Wall Solutions

You will have seen LED video walls, anywhere where a large single static or moving picture is needed for example at a sporting or concert venue.








LED screens have been used at these types of venues for years; they are ideal solutions for showing large images in large spaces. LED screens are IP rated, preventing the ingress of foreign bodies and moisture, so more favourable for outdoor locations. It’s only fairly recently that LED technology has been enhanced for smaller scale indoor use. Indoor LED technology has consistently improved and no doubt will continue to do so. Indoor LED tech has moved on from containing block text and difficult to interpret graphics. LED’s have become more affordable with better resolution delivery (as little as 0.7 pixel pitch) and include features from manufacturers making mounting and connectivity simpler.








LCD screens have been the preferred indoor video wall option since indoor video walls became a thing. LCD video walls offer ultra high definition, the ability to display single large format display or multiple feeds of different information, images and video. The only drawback being that because the display is made up of a number of screens there isn’t an uninterrupted image, there are always screen bezels to contend with, though it has to be said these have significantly reduce of late to as little as 1.8mm, after a while you don’t even really notice them. To use an LCD wall in an outdoor location would require an enclosure as they aren’t IP rated.
