What is the "e ink e paper" display?
E-Paper displays use microcapsule electrophoretic technology for display: charged particles suspended in a clear liquid will move to the sides of the microcapsule when an electric field is applied, making the microcapsule visible by reflecting ambient light, just like traditional printed paper. The E-Paper Display clearly displays images/texts under lamp or natural light, no backlight required, and a viewing angle of nearly 170°. This type of display is typically used in e-book readers due to its paper-like effect.
Main features of the e-paper screen
- No backlight, it displays the last content for a long time, even when the power is disconnected
- Very low power consumption, power only required to refresh the image
- SPI interface, compatible with Arduino , Raspberry Pi , STM32 , Jetson Nano etc.
- Built-in voltage regulator compatible with 3.3V/5V boards
Suggested use
E-paper displays are characterized by very low power consumption, making them ideal for:
- Display labels and prices in supermarkets
- Presenting user data at conferences
- Representing disease descriptions and patient charts in hospitals
E-paper screens are characterized by very low energy consumption.
Shield leads.
