Why choose a signage display with E-Paper technology?

A signage display with E-Paper technology offers a number of advantages that make it an attractive choice for various applications:

How do E-paper displays work?

E-paper displays, also known as electronic paper or e-ink, are display technologies designed to replicate the appearance of ink on traditional paper.


Unlike most conventional screens, which emit light (i.e. are backlit), e-paper displays typically reflect ambient light. E-paper technology is based on the principle of electrophoresis and uses electronic ink in the form of charged particles in microcapsules. The capsules, which are around 40 micrometres in size, contain white and black pigments with different charges. Electrical voltage is used to move the black and white pigments to the surface of the display or into the background. The pigments on top are then visible to the viewer.

It is possible to display up to 16 shades of grey. For this purpose, the electrical voltage is controlled in such a way that only a certain proportion of the pigments of each colour reach the surface. Coloured representations are made possible either by colour filters or by additional coloured pigments in the capsules.

A key feature of the technology is that once an image has been generated, it remains visible without any power supply; power is only required for changes to the image content. Compared to other display technologies, however, a lot of time is needed to change the image, which is why e-paper displays are particularly suitable for static images and text.

How E-Paper works! The underlying E-Ink technology is based on the principle of electrophoresis and uses electrical voltage to arrange the colour pigments in the microcapsules in such a way that an image is created.

This is what e-paper, LED walls and LCD displays look like under the microscope!

Modern E-Paper displays are setting new standards in colour reproduction - but which technology is the right one for your application?

Spectra

E-Ink Spectra technology, specifically Spectra-6, is an industry standard that enables an expanded colour gamut and more accurate colour reproduction. This technology is crucial for the ability to display colour content with good visibility and high contrast. The colour space can include up to 65,000 colours, with six colours (red, yellow, green, blue, white and black) per pixel.

Kaleido

Kaleido 3 technology is used for the outdoor E-Paper, which is characterised by its particular suitability for outdoor use. A major advantage is the wide operating temperature range of -15°C to +65°C, which enables use in various climatic conditions without additional heating or cooling devices. The dynamic colour reproduction with 4096 colours enables a varied display of content.

In which application areas are E-Paper displays used?

Retail trade

  • Digital price tags: E-Paper displays allow prices to be updated quickly and easily without the need to manually replace price tags. The low power consumption keeps operating costs low.
  • Advertising posters and promotional displays: Good legibility, 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.

Gastronomy

  • Digital menus: E-Paper adverts allow the menu to be adapted flexibly and quickly, which is particularly useful for seasonal or daily changes.
  • Displaying special offers: Easy updating allows current information to be communicated quickly and efficiently.

Offices and public facilities

  • Information displays: E-Paper displays offer a reliable and easy-to-read display of important information, e.g. of offices and public buildings or as a display on exhibits in museums and can also be used in locations without a direct power connection.
  • Room booking systems: E-Paper displays offer a clear presentation of room occupancy. Some models also allow direct booking of meeting rooms. Wireless mounting and long battery life make installation easier.

Outdoor areas (DOOH)

  • Digital outdoor advertising: Outdoor E-Paper displays are specially designed for outdoor use and offer good legibility even in direct sunlight.
  • Passenger information: Easy-to-read information for passengers at railway stations, airports and bus stops thanks to 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.

Sample calculations

Depending on the application of the e-paper displays, different content update cycles may be appropriate. This table provides an illustrative overview of common update cycles and the resulting battery life of the devices.
