 # Using TFT-ST7789 display on Duo S
 
-## Hardware wiring
+## Working Principle
+The principle of liquid crystal display is based on the characteristic that the transmittance of liquid crystal changes with the voltage applied to it. The TFT screen is usually composed of RGB (red, green, blue) sub-pixels. By adjusting the brightness of each sub-pixel, different colors of light are combined to achieve full-color display. And use the SPI interface.

 # 在 Duo S 上使用 TFT-ST7789 显示屏
 
-## 硬件接线
+## 工作原理
+液晶显示的原理基于液晶的透光率随其所施电压大小而变化的特性，TFT 屏幕通常由 RGB（红、绿、蓝）子像素组成。通过调节每个子像素的亮度，结合不同颜色的光，以实现全彩显示。并且使用SPI接口。
