e-paper screen shows low-power-display option on IoT development board

November 08, 2017 //By Graham Prophet
Pervasive Displays (Pdi) (Tainan City, Taiwan), maker of e-paper displays is supplying its ultra-low power product to be featured on Cypress Semiconductors’ PSoC 6 IoT development board.

The combination supports development of designs that can incorporate displays without significantly impacting power budgets, for example in portable health monitors, utility meters and other connected monitoring and control devices.

 

E-paper displays use much less energy than a traditional TFT liquid crystal display (LCD), because they require no backlight and do not need to be refreshed constantly to maintain a visible image. An always-on e-paper display, updated half-a-dozen times a day, can use as little as 0.001% of the energy of an LCD equivalent performing the same role. This means a device with an e-paper display can run for months or even years on a small battery.

 

E-paper displays also offer very wide viewing angles, and because they’re reflective, can be read in bright sunlight and by barcode scanners, unlike TFT LCDs.

 

Cypress comments, “Pervasive Displays was the ideal partner to implement the display on our PSoC 6 BLE Pioneer Kit [combining] processing performance with an ultra-low power architecture and the flexibility to design differentiated IoT applications.”

 

The Cypress PSoC 6 BLE Pioneer Kit is stocked by distributors including Mouser, Digi-Key, RS Components, Future, Arrow and Farnell.
