LCD与LED液晶显示屏的区别 lcd与led哪个更好？

Answer 1

LCD用类似于节能灯的灯管作背光源

LED用发光二极管作背光源

LED更节能，LED的光线更柔和，更接近自然

还有一种LED电视，直接由很多发光二极管组成显示屏而没有背光灯，这种电视色彩更自然，也更节能，但是价格十分昂贵。

Answer 2

lcd 是 liquid crystal display 的简称。LED液晶显示屏是发光二极管原理制成的液晶屏，优点如下：一、体积小
LED基本上是一块很小的晶片被封装在环氧树脂里面，所以它非常的小，非常的轻。
二、耗电量低
LED耗电相当低，一般来说LED的工作电压是2-3.6V。工作电流是0.02-0.03A。这就是说：它消耗的电能不超过0.1W。
三、使用寿命长
在恰当的电流和电压下，LED的使用寿命可达10万小时。
四、高亮度、低热量
LED使用冷发光技术，发热量比普通照明灯具低很多。
五、环保
LED是由无毒的材料作成，不像荧光灯含水银会造成污染，同时LED也可以回收再利用。
六、坚固耐用
LED是被完全的封装在环氧树脂里面，它比灯泡和荧光灯管都坚固。灯体内也没有松动的部分，这些特点使得LED可以说是不易损坏的。

LED液晶屏是LED背光而已，LCD液晶屏则是CCFL背光，除了背光不同之外，屏本身没啥区别了，当然，由于背光不一样，他们的性能和功能是存在区别的，相对来讲，LED屏更加节能、环保，但是LCD屏的色彩效果会比LED的好些，个人推荐用LED屏，具体还要看你使用的要求是怎么样的，希望能够帮到你！还有疑问可以联系我哈··

we can see it from the monitors, it can help you understand it better,
The debate between LED vs LCD monitors has been going on since LED’s hit the market. So, what is the difference between LCD and LED monitors?
What’s the Difference?
The difference is the back-light of the monitors. While the technology of the displays of LCD’s and LED’s is basically the same, the LCD monitor uses cold cathode fluorescent lamps as back-lights as compared to the LED monitors that emit diodes. While this is not the only difference between the two, this is the main difference, and a major point of contention between those who prefer LCD technology and those who prefer LED technology.

The old CRT monitors generated their own light by using their cathode rays. LCD technology, on the other hand, depends on outside lighting to create the image and project the display colors by manipulating the light that traverses polarized liquid crystals
