E-paper: a flexible digital poster

Is the era of paper posters truly over with the arrival of e-papers? And is digital signage completely overrated, now that e-papers are entering the picture? The fact is: this emerging technology clearly offers many advantages and has developed significantly in recent years. We are happy to share some of the key advantages and concerns of e-papers in this blog.

What is an e-paper?

To start with, let us define what an e-paper is. An e-paper, also known as electronic paper or a digital poster, is a display technology that mimics the appearance of ink on paper. It is static, just like a traditional poster. This means that no animation or movement of any kind is possible. 

However, the major advantage over a regular poster is that this static display is digital. This means that – if the displayed content is no longer relevant – you can quickly upload new content. The 'canvas' remains the same, but the content – what you show– is easy to update.

E-paper versus LCD

We are often asked whether e-paper will replace traditional LCD screens. The answer here clearly: no it isn’t ;-). 

Digital signage is much more dynamic thanks to the ability to display moving images, animations, and videos, and to schedule multiple items in a continuous content loop. 

By contrast, e-paper is a static medium, and is therefore more of an alternative to static poster communication. For instance, people often don’t refer to ‘inches’ when talking about e-paper, but instead use familiar paper sizes like A1, A2 and A3.

So as far as we’re concerned, e-paper is more of a complement – and certainly not a replacement – for digital signage.

Advantages of an e-paper

1. Sustainable and energy-efficient

The biggest advantage is easy to guess: an e-paper is an environmentally friendly and sustainable alternative to the paper poster communication. It helps reduce paper waste and is also very energy-efficient. As soon as the content is displayed, an e-paper no longer needs power and therefore does not consume energy! 

2. Flexible use

Since the e-paper no longer needs power once the new content is uploaded, you can place it anywhere in your shop or business (no need for a power plug nearby). This offers tremendous flexibility and allows you to highlight a particular product or communicate a promo in a particular shop area.

3. Beautiful image quality

Although the technology has been around for some time, it has evolved rapidly and improved significantly in recent years. Today, e-paper offers a particularly wide colour spectrum, making it a full-fledged alternative to traditional poster communication. Thanks to this wide colour gamut, e-paper provides the perfect canvas for displaying high-quality content. 

Did you know: although the vast majority of e-papers are currently designed for indoor use, at EuroCIS we also spotted an e-paper from DynaScan that can be used in a shop window. One of the few e-paper solutions currently suited for that purpose.

4. Quickly adaptable

Since the content is displayed digitally, customisation is quick and easy. With a USB stick, you can upload new content, which becomes visible on the e-paper within 10 to 30 seconds. 

This process may become even more user-friendly in the future. For example, many manufacturers are already exploring the use of Content Management Systems (CMS), so that content can be managed centrally. To be continued!

5. Various applications

E-paper can be used in a wide range of markets and applications. From digital price tags in retail to menu boards in restaurants, promotional displays, or even digital name tags outside patient rooms. This makes it a promising product that could eventually replace much of today’s paper poster communication.

And while current e-paper formats range from 13" to 32", work is actively underway behind the scenes to develop larger formats as well. So over time, even more applications will become possible!

Is E-paper conquering the market?

There is already considerable buzz around this technology, and we too believe that e-papers will gradually find their way into a variety of markets, including retail. Technology is advancing quickly, and with the emergence of new formats and robust content management systems, e-papers are set to replace many paper posters – making them a sustainable addition to the digital signage landscape ;-).
