LED Vs LCD TV

We live in an age, where we face a problem of abundance, in choosing technology. Choosing a TV used to be a simple job a few decades ago, but not anymore. There are LCD TVs, plasma TVs and now we have a new entry in the form of an LED TV. LED (Light Emitting Diode) technology is slowly making inroads into the consumer electronics market, due to the electric power economy that it provides. In this article, I present an LED vs LCD TV comparison, which will clear out the confusion between the two technologies.

For those of you who haven't yet recovered from the CRT (cathode ray tube) TV hangover, LCD and LED TVs are totally new technologies. Compared to the power consumption of CRT TVs, LCD and LED TVs are very low consumption devices. Let us see how these two types of television sets differ in their design. This will help clear out a lot of confusion people have about LED TVs, which are relatively new entrants in the consumer electronics market.

LED vs LCD TV Comparison

What sets LED and LCD technology apart from CRT, is the fact that they don't need a power consuming cathode ray tube for their operation. At the very beginning, let me identify the difference in designing of LED and LCD television sets. After that, we may discuss other differences in features that include difference in power consumption and the overall cost of these electronic devices.

LED vs LCD TV: Difference in Technology
The technology that makes LED TVs possible is not entirely different from LCD. In fact, it is a modification of the original LCD design. You could say that LED TVs are an improvement over LCD TVs. In both technologies, images are created by modification of the 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. The difference in LED and LCD TVs lies in the backlighting used. While cold cathode fluorescent lamps act as the backlighting mechanism for LCD TVs, light emitting diodes are used in LED TVs. That's the only prime difference. The difference in illumination also leads to a substantial difference in picture quality. LED TVs offer a better gradation in color scheme, compared to LCD TVs. The light emitted by LED TVs also tends to be softer on the eyes than LCD ones. This is an important point in LED vs LCD monitor comparison.

LED vs LCD TV: Power Consumption
With regard to LED TV power consumption, it is known that they tend to be a lot more economical in electrical power use. 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 translated into low level 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 win this round of LED TV vs LCD TV comparison.

LED vs LCD TV: Cost Comparison
While LCD has higher power consumption, it has an advantage over LED TVs when it comes to 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 LCD TVs. However, with time, the prices are expected to go down substantially. A helpful tip would be to go through a few LED vs LCD TV reviews offered by websites dedicated to consumer electronics.

I hope this LED vs LCD TV comparison has succeeded in what it was written for and your confusion regarding the two slightly different display technologies has been cleared out. I would personally recommend that you opt for an LED display, as it provides better overall performance.
