Of late, we have been seeing many television sets with various advancements in technology. In the current market scenario, there are 2 TV’s that are very popular: LCD TV and LED TV.
Before jumping directly in to the topic, let’s see what is what and then we will discuss some primary features like brightness, color accuracy, cost, contrast ratio, longevity, power consumption, viewing angle, etc,.
Liquid Crystal Display(LCD) TV’s uses LCD display technology to produce images. LCD televisions are thinner and lighter than cathode ray tube (CRTs) of similar display size, and are available in much larger sizes.

LCD uses Cold Cathode Fluorescent Lamps(CCFL) for the illumination purpose.
As far as the market & the commercials are considered, LED technology is the successor of LCD technology. In fact, that is not correct and just misleading the consumers.

LED is just an LCD with a different source of back-light that illuminates the screen. The light source used here is nothing but Light Emitting Diodes (LED), hence the name.
LED TVs are the brightest available in the market now-a-days. Too bright that they can blind you if you watch in dark room without adjusting the brightness. It doesn’t mean that LCDs are dull
but they are just not as bright compared to LED.
If you watch a lot of TV during the day, or have a room with lots of windows, an LED TV is probably best.
It’s a complete marketing hype that LED produces better colors compared to the LCD. But the fact is, color reproduction depends completely on the color filters that has been used by the manufacturer and is independent of the light source, which is CCFL & LED in this case.
Hence both gets equal points here.
LCD TVs are the cheapest offering from any manufacturer in the market (forget the antique cathode ray TV sets).
So if cost is a factor, consumers should settle with budget friendly LCD TV instead of opting for a costlier LED TV.
LED TVs are by far the costliest of both. So points for LCD here.
Contrast ratio, or the ratio between the darkest part of the image and the brightest, is one of the most important factors in overall picture quality. A display with a high contrast ratio is going to seem more realistic, and have more virtual “depth”.
LED TVs have a contrast ratio much higher than the LCD counterparts, which results in a better picture quality in LED as compared to LCD. Hopefully with the upcoming upgrades, LCD TVs are going to perform better in this category.
So, for now, LED TV is a clear winner when contrast ratio is considered.
With the advancements in the technology and the improvisation of manufacturing processes, both LCD and LED will have long life, say>5 years.
In fact, nobody is so sure about the exact life of the TV whatever the technology they use. So it’s a tie for LCD and LED here.
LCD uses an older CCFL source for illumination which is power hungry compared to the latest LED which uses far less power. But again, it doesn’t mean LCD is utilizing vast amount of electricity, we just mean that with respect to LED.
So if you are ready to shell out some extra bucks and go green, you should get the LED.
Some manufacturers bloat out that their sets have a wide viewing angle, but in fact both LCD and LED lose picture quality when viewed at certain angles not directly in front of the screen.
So its hard to say who’s the clear winner here.
Black Chilled Says:
Whatever the TV is called LCD or LED, both are same TV’s with different back light illumination. Hence we can simply call CCFL LCD and LED LCD.
Lately, some manufacturers are phasing out LCDs from their portfolio and making LED as the only choice available to the consumer.(As far as I know, Samsung released no LCDs in India during financial year 2012-13).
So far so good. Now its time to take the final decision. We simply can’t decide just by analyzing the above mentioned features, we also need to weigh the options as per the requirement and make the call.
Hence let’ s consider different basic scenarios for us:
For gaming, it requires TVs with faster refresh rate since the objects will be moving at a rapid pace. So in order to avoid blurring of objects. TVs with higher refresh rate is preferred.
But in case of LCD or LED, the underlying technology is the same, except the back-light which doesn’t affect the refresh rate in any way.
So, provided higher refresh rates, both LCDs and LEDs are preferred for gaming.
Brightness comes into play here.
If we want to keep the TV in an open room/lounge with many windows, LED’s are preferred since their brightness levels are higher compared to LCDs.
of darker rooms, LCD is preferable and cost
Considering fixed dimensions, LCDs are way cheaper than LEDs. i.e.32″ LCD
is lot cheaper than 32″ LED.
So suppose if cost is a factor, you should probably settle down with LCD, else, you can go for LED.
If you think that LED consumes less energy so that it will cover the extra spending on TV and make a call to go for it, then that’s a bad idea, since it will take years to make up that difference considering energy savings of just few bucks per year.
Quality of Product as well as picture:
Quality of the product always depend on the manufacturer, so better go for the prominent manufacturer in the market.
Also, the quality of the picture depends on the materials used and the manufacturing process followed. Hence once again you should choose prominent manufacturers out there for best results.
Manufacturers like Samsung, Philips, Sony, Panasonic, LG, Toshiba, Sharp are among the preferred ones.
