E-Paper displays
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.
This is what e-paper, LED walls and LCD displays look like under the microscope!
The difference between the E-Paper technologies explained!
Modern E-Paper displays are setting new standards in colour reproduction - but which technology is the right one for your application?
In which application areas are E-Paper displays used?
E-paper battery life calculator
Use the calculator below to specify how often the content displayed on the e-paper display should be updated and over what period. You will then be shown the estimated battery life for the Samsung EM32DX-A and Samsung EM13DX models.
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.
| Scenario | EM32DX-A | EM13DX |
| 1 update / 1 day (e.g. special offers changing daily) | 72 (Sleep) – 83 (Deep Sleep) days | 69 (Sleep) – 80 (Deep Sleep) days |
| 3 changes / 1 day (e.g. daily menu for breakfast, lunch and dinner) | 27–29 days | 69–80 days |
| 1 change / 7 days (e.g. weekly booking schedule for seminar rooms) | 198–336 days | 313–763 days |
| 1 change / 30 days (e.g. monthly updates to bus timetables) | 270–600 days | 338–937 days |
