LCD vs. LED TVJune 6, 2016
Affordable electrical appliances in the Philippines are aplenty thanks to the advancements in technology. Gadgets, appliances, and electronic devices – all of them were upgraded to fit the busy lifestyle of people nowadays. Even televisions, which have been around for years, are continuously being innovated.
Truly, the television has come a long way since the three-inch screens of the early 20th century. Through time, its design evolved from box-like contraptions into wide flat-screens and high definition displays that are crisp and colorful. Now, instead of humongous televisions, companies are producing LED and LCD TVs. While the acronyms can be a little confusing especially to novice buyers, there really is a difference between the two.
LED TV is an LCD TV
Despite having a different acronym, the LED TV is really just a different type of LCD TV. The proper name of this appliance is “LED-backlit LCD TV”, which is rather mouthful during a conversation hence the reason why people refer to them as LED TV.
In truth, both types of TV make use of a liquid crystal display (LCD) panel to control the light being displayed on the screen. The panels are usually composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align so that the light can or cannot pass through. These crystals can be compared to window shutters; either they allow the light to pass or block it.
The Difference between LED and LCD TV
The difference between the two is simply the backlight. Ordinary LCD TVs use cold cathode fluorescent lamps (CCFL’s) to provide backlighting, whereas LED TVs use smaller and more efficient light emitting diodes (LEDs) to illuminate the screen. In this regard, the latter has a bit of an edge over LCD TVs.
With regards to picture quality, some say that LED TVs are better. In reality, there really is no straight answer because both displays use the same kind of screen. A high-end LCD TV, for instance, might have a better quality than a low-end LED TV. When it comes to size and design, there is also no winner between LED and LCD televisions since – depending on the manufacturer – both can come in slim frames; some are even one inch thick only!
In terms of power consumption, LED TVs are more efficient since its light emitting diodes are smaller than CCFLs. Naturally, this means they consume less power. The most important difference between the two is a feature called local dimming – a selective lighting technique that allows for deeper blacks and better overall picture while watching TV. The problem with CCFL backlighting is that the fluorescent tubes must light the entire screen evenly, so the designers can’t vary the backlighting intensity to the different parts of the screen. LEDs, on the other hand, offer the local dimming feature. This technique controls the output of LEDs so that they can be dimmed or turned off entirely rather than be on full brightness all the time.
When it comes to prices, LED TVs are priced higher than LCD TVs. Since the former has plenty of advantages over the latter, they come at a higher price.
When it comes to choosing the right TV for you, make sure to consider every feature first before making a purchase. Take note of the differences between the two displays before deciding which one would suit your needs best. In the end, whether you choose an LED or LCD TV, you will surely have an exciting time watching your favorite TV shows.
