3 Inch 4 Color E Ink Display 400x168 SPI Interface for RPi Description

1、SPI CONTROL INTERFACE: E paper display is SPI control interface, which can access for RPi, for Jetson nano, for STM32 and other main control boards. Power consumption is very low, basically only when refreshing. 2、NO BACKLIGHT REQUIRED: E paper display module does not need backlight and can keep the last screen display for a long time when power off. It is often used in applications such as readers. 3、UNIQUE TECHNOLOGY: E paper module uses microencapsulated electrophoretic display technology for image display, which creates a display effect close to that of traditional printed paper by reflection under ambient light. 4、WORKING PRINCIPLE: Electronic ink screen module works on the principle that charged nanoparticles suspended in a liquid are subjected to an electric field that causes them to migrate. 5、VIEWING ANGLE 180 DEGREES: Electronic ink screen is capable of displaying images clearly in ambient light, such as light and natural light, with a viewing angle of almost 180 degree, giving you the best using experience.
