 # Use Pico-ePaper-2.13 display on Duo S
 
+## Working Principle
+
+Using SPI communication interface, the "microcapsule electrophoresis display" technology is used for image display. The basic principle is that charged nanoparticles suspended in liquid migrate under the action of electric field. The electronic paper display screen displays patterns by reflecting ambient light and does not require backlight. Under ambient light, the electronic paper display screen is clearly visible, and the viewing angle reaches almost 180°. Therefore, the electronic paper display screen is very suitable for reading.

 # 在 Duo S 上使用 Pico-ePaper-2.13 显示屏
 
+## 工作原理
+
+使用SPI通信接口，采用“微胶囊电泳显示”技术进行图像显示，其基本原理是悬浮在液体中的带电纳米粒子受到电场作用而产生迁移。电子纸显示屏是靠反射环境光来显示图案的，不需要背光，在环境光下，电子纸显示屏清晰可视，可视角度几乎达到了 180°。因此，电子纸显示屏非常适合阅读。
