LED vs. LCD TVs – Which is Which?

Shopping for a TV set can a daunting process. This is attributed to the fact that the number of manufactures and TV designs keep evolving thus further complicating the buying process. Some of the latest television models are plasma or LCD TVs and Light Emitting Diodes TVs. These two TV models have distinct features that set them apart. Here is an in-depth look at fundamental differences between LCD and LED TVs.

Technological Differences

This is one aspect that differentiates LCD and LED televisions. Ideally, LED TVs are a product of more recent technological advancements, while the LCD units are made from relatively old technologies. From a technical point of view, LED TVs are somewhat superior and LCDs.

Image Quality

Both the LCD and LED TV sets use polarization of liquid crystal material technology to create images. This material is found within a transparent enclosure. In both of these television types, illumination is achieved using a back-light feature. This light illuminates liquid crystal, and this brings about image formation.

The Picture quality differs between LED and LCD. This is attributed to the differences in source light. LED televisions produce quality pictures compared to the LCD TV model. Besides, LED TVs deliver light that is gentle on eyes compared to the LCD TVs.

Source of Backlight

As stated earlier, both LCD and LED TVs use a backlight to light up the liquid crystal that is responsible for image formation. The difference comes in the source of light or how light is projected to the screen. For, LCD TV model sources its backlight from cold cathode fluorescent lamps. On the other hand, LED TV models use light emitting diodes.

Power Consumption

In regards to power consumption, LEDs consume less power compared to LCDs. LEDs use solid-state semiconductors, which require low amounts of energy to light. Therefore, the heat generated is minimal. This explains why LEDs are known to consume less energy than LCDs. Thus, LED TVs are a perfect choice where power consumption is of concern.
