Advantages of E-Paper displays for IoT applications

Recommended Posts

E-Paper displays offer a unique advantage in that maintaining the displayed image does not require any power, unlike LCDs and OLEDs. Power is only actively consumed when updating the display, However, the downside is that display updates can be somewhat slow, depending on the display area to be updated.

The unique features of E-Paper displays makes them a good match for low-power IoT projects, since the microcontroller can set the display and go into sleep mode, only waking up to read sensor values and update the display. This demo project shows how a RTL8722 microcontroller can be used to show the temperature and humidity with a E-Paper display.
