谁能告诉我LCD显示原理和结构?
LCD 的构造是在两片平行的玻璃基板当中放置液晶盒,下基板玻璃上设置TFT,上基板玻璃上设置彩色滤光片,通过TFT上的信号与电压改变来控制液晶分子的转动方向,从而达到控制每个像素点偏振光出射与否而达到显示目的。
设计一个电路原理图:使用光敏二极管将光电流转换光电压并用LCD显示出来?
你给的条件不是很清。但是我知道。你是想把电流转换成电压信号。 并且要用上光敏二极管。你可以把你的条件用真值表列出来,然后卡诺图化简以后自然就出来你的电路了。
光电流转换为电压后,可将该电压用经过放大电路后送入AD采样经单片机处理后,输出到LCD上显示出来。
基于单片机的LCD接口电路设计
机器加工表面缺陷的计算机定位!
你要帮我做了,我就帮你做!
网上有不少关于单片机和LCD的程序和电路图,你指的LCD接口电路设计,是在那些之上搞创新么?
