Q:

Are LCD or an LED televisions better quality?

A:

Quick Answer

As of 2015, LED televisions provide better image quality because they utilize light-emitting diodes that are more efficient than the cold cathode fluorescent lamps used by LCD televisions for backlighting. Light-emitting diodes allow an LED television to control its brightness output, which results in better contrast and black levels.

LED TVs are typically thinner when compared to LCD TVs because the light-emitting diodes are noticeably smaller than CCFL tubes. Additionally, the backlighting provided by LED TVs consumes less power, making them better in regards to energy efficiency. One of the biggest advantages of LED TVs in terms of image quality is the ability to dim certain parts of the screen. Unlike LCD TVs, which illuminate all parts of the screen equally, the local dimming technique allows LED TVs to dim individual diodes, resulting in brighter display of on-screen objects that need to be illuminated. The downside is that only full-array LED TVs can use this technology, although there are several edge-lit models that are able to mimic that functionality, including the LG LW5600 and the Samsung UND8000 series.

As of 2015, LCD TVs are quickly becoming obsolete. However, they are still more affordable than LED TVs because they typically belong to the low-end tier of TVs offered by various companies, while better image quality and higher energy efficiency account for the premium price of LED TVs.
