1. No need backlight, power off can keep the display content of the last screen for a long time, the time can be up to half a year
2. The power consumption is very low, basically only consumes power when refreshing
3. SPI control interface, can access Raspberry / Arduino / STM32 and other main control boards
4. Provide complete supporting materials (Arduino sample program, showing global display and partial display)
