摘要

This article investigates variable optical characteristics of Liquid Crystal Display (LCD). The main function of light intensity intelligent control system is to adjust the brightness of the LCD screen of automotive sun visors according to the light intensity of external environment. The working process starts sending a processed analog signal to single chip microcomputer by collecting data of environmental light through a sensor of BH1750, and then analyzes and computes through processing units, adjusts driving voltage and changes the brightness of LCD screen so that the drivers can fit the light intensity outside and drive safely.
