e-paper technology.

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.

• 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

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.
