Quick question...... What are the differences between LCD and LED tv's.

Both employ the liquid crystal diode (LCD) technology front panel containing the “twisting crystals” which define LCD technology.

LED TVs feature two main forms of back lighting, edge lighting and local dimming. Edge lighting has LEDs around the edge of the panel and this allows for extremely thin construction. Lately, through advancements in LED (light emitting diode) technology these lights can be manufactured in very small sizes so even local dimming back lighting LED TVs can have a very thin depth. Local dimming backlighting features banks of LED lights behind the panel and these banks can be controlled to lower the amount of back lighting in dark areas of the screen and raise it in bright areas for higher contrast and better blacks. This is accomplished through varying features options in the TV. One recent example had an option to turn the local dimming option on or off. We did notice an improvement in black levels with the feature on
