The comparison between LED and LCD television sets presented in this story is aimed at clearing out the confusion regarding these two technologies. Read to know all about the similarities and differences between the two.
We live in an age where we face a problem of abundance while buying a gadget or choosing a technology. Selecting a television used to be a simple job a few decades ago, but not anymore. The current market has been filled over completely with new technology devices such as LCD or plasma TVs to name a few.
Moreover, we now have a new entry in the form of an LED TV. LED, short for 'Light Emitting Diode', is a technology that is slowly making its presence felt into the consumer electronics market, due to the electric power economy that it provides.
For those of you, who haven't yet recovered from the CRT (cathode ray tube) TV hangover, LCD and LED are totally new technologies. These devices have a very low electricity consumption when compared to that of the traditional CRT TVs.
Let us understand how these two types of television sets differ in their design. This will help us interpret these technologies and get a clear overview of the LED TVs, which are relatively new entrants in the consumer electronics market.

LED Vs. LCD TV Comparison

Unlike CRT, LED and LCD technologies don't require a power-consuming cathode ray tube for their operation. This sets these technologies apart from the age-old CRT. To begin with, let us identify the difference in designing of LED and LCD television sets.

Difference in Technology

The technology that makes LED TVs possible is not entirely different from an LCD. In fact, it is a modification of the original LCD design. You could say that LED TVs are an improvement over the LCD TVs.

Image Formation

In both these technologies, images are created by modification through the process of polarization of liquid crystal materials filled within a thin transparent enclosure. The light needed for formation of images is provided by a backlight that illuminates the liquid crystal.


A difference between LED and LCD TVs lies in the backlight used. In case of a LCD TV, cold cathode fluorescent lamps or a collection of CCFLs are used as backlights, while an LED television uses light emitting diodes. This acts as the prime difference between the two gadgets under consideration.

Picture Quality

Using different sources of illumination, in turn, changes the picture quality substantially. LED TVs offer a better gradation in color scheme, compared to LCD TVs. The light emitted by LED TVs also tends to be gentler on the eyes than the LCD ones. This forms a very important point in the comparison.

Power Consumption

With regards to LED TV power consumption, they are known to be a lot more economical when it comes to the use of electrical power. Low power consumption compared to LCD TVs is attributed to the low power needs of LEDs, which are solid state semiconductor devices.
Low power consumption automatically translates into lower levels of heat generated. They consume as much as 40% lesser electrical power compared to their LCD counterparts. So in terms of power consumption, the LED TVs top this round.

Cost Comparison

While LCD has higher power consumption, it has an advantage over LED TVs when it comes to the cost. As the LED TV technology is relatively new and its manufacturing costs have not yet been downgraded by the mass production factor, LED TVs are a lot costlier as compared to the LCD ones.
However, with time, prices are expected to go down substantially. A helpful tip would be to go through a few reviews offered by websites dedicated to consumer electronics.
In a nutshell, LED surely has an edge over the LCD technology in terms of the picture quality, image display, or even power consumption. Thus, for a better overall performance, LED display television is certainly the apt choice.
