LCD and LED televisions use similar technology for creating the picture, but LED televisions have a significantly higher contrast ratio. LCD televisions typically have a contrast ratio between 1,200:1 to about 3,500:1, while LED televisions can have a contrast ratio up to approximately 40,000:1.
Both LED and LCD televisions use LCD technology to generate the image, but LCD-labeled televisions use fluorescent lighting, while LED television use significantly brighter LEDs. This higher contrast ratio results in brighter colors, but it also allows the television to display darker blacks, which leads to a more-accurate and cinematic picture. LED televisions also consume approximately 40 percent less power than their LCD counterparts and can be significantly thinner.
