Low energy consumption
E-paper displays consume virtually no power when in a static state. Energy is used solely to refresh the screen content. As a result, battery-powered models can operate entirely independently for up to a year.

Technology explained simply: What is an e-paper display?
Content
Significant cost savings
Depending on how they are used, e-paper displays account for just one to two per cent of annual electricity costs compared with LCD displays. This results in significant cost savings compared with conventional digital signage solutions.
Sustainability and recycled materials
Thanks to their low energy consumption and environmental friendliness, e-paper displays offer businesses a sustainable alternative to paper posters. Some models are even made from recycled plastic and come in eco-friendly packaging.
High readability, just like on paper
E-paper displays offer excellent readability, even in direct sunlight. They reflect ambient light in much the same way as paper, making them glare-free and ideal for use outdoors or in any setting where paper posters were previously used.
Versatility and flexibility
E-paper displays are available in a range of sizes. The selection ranges from small 13-inch displays to large 75-inch models. The displays are easy to install and can be mounted on walls, ceilings or tables. Some models are wireless and equipped with batteries, which makes positioning them even easier.
Simple content management
The content displayed on e-paper displays can be easily managed and updated using content management systems such as Samsung VXT or dedicated apps. Many displays also offer functions for remote maintenance and scheduling.
E-Ink or e-paper – what’s the difference?
Good to know: E-paper as a display technology should not be confused with the term ‘e-paper’, which in everyday language often refers to the digital edition of a newspaper or magazine.
The technology behind it: How the image is created
This is what e-paper displays, LED walls and LCD displays look like under a microscope:

Specta
Specta
E-Ink Spectra technology is the standard for indoor use. This technology is crucial for the ability to display colour content with good visibility and high contrast. The colour gamut can encompass up to 65,000 colours, with six colours (red, yellow, green, blue, white and black) capable of being displayed per pixel.
Kaleido
Kaleido
The outdoor e-paper utilises E-Ink Kaleido 3 technology, which is particularly well-suited to outdoor use. A key advantage is the wide operating temperature range of –15 °C to +65 °C, which allows it to be used in a variety of climatic conditions without the need for additional heating or cooling equipment. The dynamic colour reproduction, with 4,096 colours, enables content to be displayed in a variety of ways.
Versatile e-paper displays: Discover all the applications and benefits
01
Retail
Digital price tags: e-paper displays allow prices to be updated quickly and easily without the need to replace price tags manually. Their low power consumption keeps running costs down.Advertising posters and promotional displays: Their excellent readability, even in bright ambient light, makes them ideal for presenting advertising messages. Not only can you change the content flexibly, but you can also easily move the displays to different locations.
02
Catering
Digital menus: e-paper displays allow for flexible and rapid adaptation of the menu, making it effortless to implement seasonal or daily changes.Displaying special offers: Thanks to the ease of updating, the latest information can be communicated quickly and efficiently.
03
Offices and public facilities
Information displays: e-paper displays offer a reliable and easy-to-read presentation of important information, e.g. in offices and public buildings or as displays accompanying exhibits in museums, and can also be used in locations without a direct mains power supply.Room reservation systems: e-paper displays provide a clear overview of room occupancy. Some models also allow meeting rooms to be booked directly. Wireless installation and long battery life make installation straightforward.
04
Outdoor areas
Digital outdoor advertising: Outdoor e-paper displays are specifically designed for outdoor use and offer good readability even in direct sunlight.Passenger information: Easy-to-read information for passengers at railway stations, airports and bus stops via e-paper displays.

Power cost comparison: how much does a conventional display cost to run?
Important note
All calculated values are intended solely for orientation and illustration. They do not represent a guaranteed minimum runtime. The values shown here are specific to the models EM32DX-A and EM13DX from Samsung. They are not intended as a representative benchmark for E-Paper devices from other manufacturers or in other sizes. Battery runtime is calculated on the basis of the power consumption measured by the manufacturer. Therefore, the actual battery runtime may vary depending on various factors such as network environment, content update frequency, battery service life, duration of user activity, image size, extreme heat or cold, etc. In addition, the battery runtime stated in the simulator may change due to changes to hardware components, firmware updates or changed environmental conditions during use. In the simulation, the duration of user activity, meaning the additional time during which the device is considered switched on due to manual operation, is included at approx. 1 minute. Automatic updates intended to prevent image burn-in are also included. Image size of the referenced content: 1.x MB. The electricity cost comparison compares a standard signage display with an E-Paper display. Power, electricity price and operating time can be freely adjusted; the default settings are 55 W, 35 p/kWh and 24 hours of operation per day. The E-Paper costs take into account the battery charges required in the respective period (battery capacity 17.71 Wh, including approx. 15% charging loss). The power consumption of individual displays can be found in the respective data sheets. The actual power consumption during operation may differ. All information and calculations are provided without guarantee.
- E-paper displays only consume power when the content on screen changes. This means that e-paper displays can also be used when powered by batteries, whereas traditional digital signage displays require a constant power supply. The savings achieved through e-paper displays can therefore amount to several hundred euros over a three- to five-year period. You can use our battery life calculator to simulate the potential savings.
- The range extends from compact formats starting at around 13 inches (e.g. for room bookings or as price labels) through 25 and 28 inches up to 32 inches for larger digital signage applications. The most suitable size depends on the viewing distance and the location. Our team will be happy to provide consulting services.
- Modern e-paper displays can also display content in colour. Indoors, E-Ink Spectra 6 technology is used, offering up to around 65,000 colours, whilst outdoors, Kaleido 3 technology is used, offering 4,096 colours. For text-heavy applications, pure black-and-white models with up to 16 shades of grey are still available.
- Yes, e-paper displays featuring Kaleido 3 technology, which are specifically designed for outdoor use, operate within a temperature range of -15 °C to +65 °C. They remain clearly legible even in direct sunlight, making them ideal for passenger information, signposts or digital outdoor advertising.
- E-paper displays are not designed for videos or fast-moving content, as the image refresh rate is relatively slow. They are particularly well suited to static content such as prices, menus, information or signage. For dynamic video advertising, we recommend LCD displays or LED walls.
- Content can be uploaded wirelessly via software or a content management system. Depending on the model, the transfer takes place via Wi-Fi or Bluetooth. Alternatively, content can also be transferred to the e-paper displays via a USB stick. Thanks to battery operation and wireless installation, many devices can also be installed independently in locations without a mains power supply.
- The term ‘e-paper’ refers to the hardware – that is, reflective, particularly energy-efficient displays that look like paper. The term ‘e-paper’ is mostly used in everyday language to refer to the digital version of a daily newspaper or magazine.
