Light Emitting Diode (LED):
LED is a type of LCD that actually accompanies the advancement of technology. This replaces the fluorescent tube with backlight technology, which produces a clearer picture than the LCD. LED have wider viewing angle than the LCD. It have better black level and contrast in comparison to LCD LCD display. LED delivers better color accuracy in comparison to the LCD.

Liquid Crystal Display (LCD):
An LCD is a passive device, which means that it does not deliver any light to display characters, animations, videos, etc. LCD uses fluorescent tubes to lighten the picture, but can’t provide the clearer picture as LED delivers. It delivers good color accuracy, but we can notice the difference if we compare LED and LCD color accuracy. In LCD, the wide angle decreases with 30 degrees from the center in the image then the contrast ratio.
Advantage:
Disadvantage:
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. |
