Design win; e-paper, ultra-low power displays enable the ‘service button’
With each one incorporating a Pervasive Displays 2-inch e-paper module to form the basis for a simple user interface, Spur implementations consist of remote, battery-powered units that are wirelessly connected to a cloud server. When activated, they communicate with the connected network and give instant visual feedback to the user. This flags that the service request is being dealt with (e.g. asking for a hotel room to be cleaned or a coffee machine to be refilled). Because they are not reliant on any additional infrastructure, Spur units are quick, easy and cost effective to deploy. As a result, they are already seeing uptake in retail, hospitality and facilities management sectors. The employment of Pervasive Displays’ e-paper technology means that Spur units can run for prolonged periods without needing battery replacement — over five years based on normal operational circumstances. Proving to be essential in achieving this are the ultra-low power capabilities of the specified display modules. They present a highly effective mechanism for rendering text and graphics that, unlike TFTs or OLEDs, only draw power when the displayed content is changed. These modules also deliver industry-leading performance in relation to sunlight readability (making them highly suited to outdoor applications) and image retention.
“Pervasive Displays’ e-paper displays furnished us with the required user interface functionality while not impacting on Spur’s power budget,” states Peter Claydon, founder and CEO of ContinuumBridge.
