LED和LCD的区别

发光二极管(LED)：
LED是一种实际上伴随着技术进步的LCD。这用背光技术取代了荧光灯管，产生比LCD更清晰的画面。 LED 比 LCD 具有更宽的视角。与 LCD LCD 显示器相比，它具有更好的黑电平和对比度。与 LCD 相比，LED 提供更好的色彩准确度。
优势：

LED有很长的寿命。

它需要低维护。

LED 不产生热量。

LED是高效的。

坏处：

它更昂贵。

它的视角有限。

液晶显示器(LCD)：
LCD是一种无源器件，也就是说它不发出任何光线来显示字符、动画、视频等。LCD使用荧光管来照亮画面，但不能提供像LED那样更清晰的画面。它提供了良好的色彩准确度，但如果我们比较 LED 和 LCD 的色彩准确度，我们会注意到差异。在 LCD 中，广角从图像中心开始下降 30 度，然后是对比度。
优势：

它消耗更少的电力。

它包括数百万种颜色。

它比LED轻。

坏处：

它需要额外的光源。

它还限制了视角。

它的速度非常慢。

S.NO	LED	LCD
1.	LED have better response time than LCD.	LCD is slower than LED in terms of response time.
2.	LED consumes more power in comparison to LCD.	Whereas it consumes less power in comparison to LED.
3.	LED delivers good picture quality in comparison to the LCD display.	LCD also delivers the good picture quality but less than LED.
4.	LED is costlier than LCD.	While it is less costlier than LED.
5.	LED have better black level and contrast in comparison to LCD.	While it have not good black level and contrast as LED.
6.	LED delivers better color accuracy in comparison to the LCD.	While it also delivers good color accuracy, but we can notice the difference if we compare these two.
7.	LED have wider viewing angle than the LCD.	While in LCD, the wide angle decreases with 30 degrees from the center in the image then the contrast ratio.
