LED显示屏和LCD有什么区别?

悬赏金额: 3 点威望


LED(Light Emitting Diode),发光二极管,是一种固态的半导体器件,它可以直接把电转化为光,用若干个LED组成的LED屏,可接驳计算机显示文字和图形,但很少用来显示动态画面。
LCD 液晶显示器是 Liquid Crystal Display 的简称,LCD 的构造是在两片平行的玻璃当中放置液态的晶体,两片玻璃中间有许多垂直和水平的细小电线,透过通电与否来控制杆状水晶分子改变方向,将光线折射出来产生画面。
LED与LCD有着根本的区别,首先是发光光源的不同,其次是显示效果的区别,LCD可显示精致画面,LED确不能。
LED理论上可做成很大的任意尺寸的显示屏,LCD目前的技太还只能做到100英寸左右。

LED显示器与LCD显示器相比,LED在亮度、功耗、可视角度和刷新速率等方面,都更具优势。LED与LCD的功耗比大约为1:10,而且更高的刷新速率使得LED在视频方面有更好的性能表现,能提供宽达160°的视角,可以显示各种文字、数字、彩色图像及动画信息,也可以播放电视、录像、VCD、DVD等彩色视频信号,多幅显示屏还可以进行联网播出。有机LED显示屏的单个元素反应速度是LCD液晶屏的1000倍,在强光下也可以照看不误,并且适应零下40度的低温。利用LED技术,可以制造出比LCD更薄、更亮、更清晰的显示器,拥有广泛的应用前景。
  LCD是液晶显示屏的全称:它包括了TFT,UFB,TFD,STN等类型的液晶显示屏。
  笔记本液晶屏常用的是TFT。TFT屏幕是薄膜晶体管,英文全称(ThinFilmTransistor),是有源矩阵类型液晶显示器,在其背部设置特殊光管,可以主动对屏幕上的各个独立的像素进行控制,这也是所谓的主动矩阵TFT的来历,这样可以大的提高反应时间,约为80毫秒,而STN的为200毫秒!也改善了STN闪烁(水波纹)模糊的现象,有效的提高了播放动态画面的能力,和STN相比,TFT有出色的色彩饱和度,还原能力和更高的对比度,太阳下依然看的非常清楚,但是缺点是比较耗电,而且成本也较高。
  简单地说,LCD与LED是两种不同的显示技术,LCD是由液态晶体组成的显示屏,而LED则是由发光二极管组成的显示屏。LED显示器与LCD显示器相比,LED在亮度、功耗、可视角度和刷新速率等方面,都更具优势。LED的分辨率一般较低,价格也比较昂贵,因为集成度更高。
   如果你看好这两个价格差不多,还是买LED的,如果差太多,就要LCD的.
LED屏是LED灯珠做光源,LCD是灯条做光源的,光源不一样,光的亮度不一样
据我知道的LED 显示屏是一个个发光二级管组成的,LCD是一种液晶显视屏!!
