Why e-paper displays will run for 22 years in coin cell powered IoT applications

Why e-paper displays will run for 22 years in coin cell powered IoT applications? By Scott Soong, CEO, Pervasive Displays You’ve carefully selected your sensor, found the lowest power MCU for your battery-powered IoT application, optimized your code to minimize energy consumption and chosen the lowest power wireless solution to send packets of data where they need to go. Now you want to figure out how to add a display to your application without completely trashing the power budget. That’s the challenge faced by many IoT product designers, for example those designing remote meters or smart tags. If they think only in terms of dot matrix displays, it’s a challenge they’ll struggle to overcome. Let’s assume that you want your display to operate for five years with CR2032 coin cell batteries as the power source. These have a typical stated capacity of 220 mAh, from which we might reasonably assume a nominal real-world operating capacity of 88% ..

5 ways e-paper displays are simplifying our lives

Millions of people love using Amazon Kindle e-readers because of the way the e-paper display looks like normal paper. There is no flickering or radiated light from the screen and no irritating glare - even in bright sunlight. E-paper doesn’t require any backlighting for daytime viewing and therefore consumes far less energy than power-hungry LEDs, LCDs and plasmas. E-paper screens will not turn dark when the power supply is cut off or if the battery runs out. It continues to hold the last image on the display until an electric charge rearranges the electronic ink particles in another pattern. This makes e-paper a great energy-saving alternative to smartphone and tablet displays and, together with low power wireless communication protocols such as Bluetooth and near field communications (NFC), product designers can let their imaginations go wild with the potential applications available. Here are 5 applications showcasing just how versatile e-paper is: E-paper makes ..
