Electrophoretic ink, often called electronic ink (E-Ink), is a technology that mimics the appearance of ink on paper. When printed onto a sheet of plastic film that is laminated to a layer of circuitry, it creates an Electronic Paper Display (EPD). EPD technology delivers look and utility of paper encompassing good readability, very wide viewing angles, design freedom, robustness, and low power consumption.
E-Ink products offer paper-like readability under all lighting conditions. Moreover, they are referred to as bistable, which means that the display is consuming power only when refreshing, giving the product extraordinary battery life of up to 5 years.
Combining E-Ink displays and Bluetooth Low Energy (BLE) technology enables transferring content flexibly to the display and also visualizing the device’s location. In addition, it is possible to track the paths and stations of the labeled objects and use this information to gain significant business insights. In order to display content on the infsoft E-Ink Display Beacon, the desired device and content are selected in the infsoft Locator Nodes Management or a corresponding app. Via Bluetooth, the content is transferred from the Locator Node to the display. The content can not only be updated manually, but also automatically – using the infsoft Automation Engine to define corresponding conditions.
For positioning, the infsoft E-Ink Display Beacon sends BLE signals to infsoft Locator Nodes that are installed in the area. The Locator Nodes process the provided data and send it to the infsoft LocAware platform®, where it is intelligently processed.
Beacons with E-Ink displays are a perfect fit for electronic shelf, door or product labels. Businesses are offered the ability to wirelessly update content on the displays quickly and efficiently, without needing to print paper tags and deploy personnel to change them manually. In real time, E-Ink beacons can display product information, status, inventory levels, barcodes, and much more. In production and logistics, for example, when assets are traced along the process chain, the display can be rewritten automatically with the current status and individual information such as instructions on the next work step.
E-Ink technology can be used beneficially in a variety of different applications.
By implementing a tracking solution with E-Ink bedside cards, relevant information concerning the hospital beds (e.g. bed position, next date for cleaning or maintenance) or the patient (e.g. surgery details) are accessible at all times.Software solution used: Indoor TrackingSensors used: Bluetooth Low Energy (beacons)Example of use: Tracking Solution with Information Display for Hospital Beds
In large production halls, the use of a tracking system with E-Ink displays with information on the employee’s next task or the occupancy status of machines/workstations can ensure smooth process flows.Software solution used: Indoor TrackingSensors used: Bluetooth Low Energy (beacons)Example of use: Indoor Tracking with Display Beacons in Logistics
In offices, E-Ink electronic door labels replace wasteful paper slip notifications, enabling companies to get control of their meeting and conference spaces. The signs can display information such as room availability and daily schedule notifications.Software solution used: Indoor TrackingSensors used: Bluetooth Low Energy (beacons)
