LED vs LCD: What You Need To Know

When considering delving into the world of Digital Signage/ DOOH/ Video Walls you may find yourself asking whether LED or LCD is the way to go, we’re here to help you with that very question. By 2024 the digital signage industry is hoping to be worth around 30 billion dollars, this just shows the impact it’s having on businesses and the boost it’s giving to advertisements. 

As you visit airports, theme parks, restaurants, casinos, stadiums and museums you will most likely come across a digital display. During the pandemic digital units have been used to provide hand sanitiser, give directions, provide safety messages and check temperatures. 

The importance of digital signage is clearer than ever to most successful businesses, but why is it hard to work out what type of signage is best for you? Not only can our team help you with this but this article should help you understand a little better.

What does LED and LCD stand for?

LED: Light-Emitting Diode
LCD: Liquid Crystal Display

How does LCD work? 

LCDs (Liquid Crystal Display) are a flat-panel display that uses light-modulating properties of liquid crystals combined with polarisers. Polarisers are an optical filter that allow light waves of a specific polarisation to pass through, whilst blocking light waves from other places to produce images in colour or monochrome. LCD is trying to keep up with the times but many competitors are getting in their way.

How does LED work? 

LEDs (Light-Emitting Diode) are a light source in the form of a semiconductor, LEDs emit light when a current flows through it. Within the semiconductor there are electrons, which have holes that release energy in the form of photons. When LEDs first started being used in 1962 they were limited to the colour red, modern LEDs are available in a range of colours with high light output.


Comparisons and Considerations 

Scanlite recently wrote about how energy efficient LEDs are, which is a huge benefit of the lights. If you’re looking for a digital sign that is going to last a long time, LED may be the answer as well. However, viewing distances are more limited with LED. You can view an LCD screen much closer, whilst LED contrast and colour will be stronger – you will need to stand a few feet back to view it at it’s best. When you’re making the decision between LED and LCD, consider where it will be located and what you are using it for. If your display is going to be close to people then you should consider LCD, our hand sanitising displays feature an LCD screen to display Covid-19 information. We knew that people would be close to this display, using the hand sanitiser feature, therefore LCD was necessary. On the other hand, if you are mounting your display or it is being viewed from further away – always go LED. Scanlite are big advocates of LED but we have displays using both, for different reasons. 

We understand that price, size and location is a big consideration when deciding which digital signage is for you. We can discuss LED vs LCD more over the phone or via email, we’d love to guide you in the right direction and cater your signage experience to your business.
