Local-dimming LED TVs
What are Local-dimming LED TVs?
Local dimming is Back-lit but individual or small groups of LED's can be dimmed independently. This is the most expensive but it produces the richest colors and the deepest blacks. Again, not as thin as Edge-lit but close to plasma in terms of contrast ratio. Local dimming comes in two varieties; all-white LEDs or groups of red, green, & blue LEDs. (Samsung 8500 series and Sony XBR8 Tri-Luminous are examples of Local-dimming LED TVs). The biggest thing to remember about LED TVs is that they offer a better picture than CCFL, they are more energy efficient (by up to 40%) and the are usually thinner.
