LED vs LCD TVs

How are LED TVs different from LCD TVs?

Simply stated, an LED TV is an LCD TV that is lit with an LED (light emitting diode) light source instead of CCFLs (cold cathode fluorescent lamp). Manufacturers such as Samsung began the trend of marketing the LED-lit LCD TV as an “LED TV” likely in an attempt to easily differentiate the product from typical CCFL lit LCD products.While an LED TV is still technically an LCD TV, just get used to seeing this type of designation. We don’t really have a problem with it and it does, among other things, seem to make it easier to say it out loud.

An LCD TV is comprised of several layers. The front layer is a piece of glass filled with liquid crystals that move and change to produce the images we see on the screen. But images can only be viewed when the screen is illuminated. This requires a light source. The light source is the difference between LED TV and conventional LCD TV.

Here’s a simple explanation of how it works: Conventional LCD TVs use fluorescent tubes (CCFL) to provide light to illuminate the LCD panel and make the images viewable. In an LED TV, the LCD panel is lit from behind with an LED-based backlight. LED lights can be more precisely controlled and can produce richer blacks and a better contrast ratio for a more vivid viewing experience.

Edge Lit vs. Rear Lit

With LED TVs, edge-lit technology is what allows some sets to be less than 1-inch thick. The LEDs are actually arranged around the very edge of the screen, allowing the display to be very thin, since the lighting technology isn’t positioned behind the screen. While this does indeed grant a thinner display, it typically (this is changing now) precludes te manufacturer from setting up a system that optimizes contrast across various areas of the screen.

Smart Dimming and Zones

Several manufacturers are optimizing their LED backlit displays to produce different amounts of backlighting on different areas of the screen. In this way, you can see content that contains bright areas on the screen along with very black areas. Think of a candle lit in a dark room. With your typical edge lit display you have one level for the overall backlight. With Smart Dimming, you can brightly light the part of the screen with teh candle, and then all but turn off the LEDs behind the black areas of the screen.

Should you expect to pay more for LED TV? What are the benefits of LED vs. LCD?

LED TVs like those form Westinghouse Digital are often edge-lit, which means they are generally more energy efficient, weigh less and cost less than full array LED TVs. Some LED TVs are engineered and produced so efficiently that they may even cost less than conventional CCFL lit LCD TVs. The bottom line is that LEDs are getting cheaper and cheaper and soon we estimate they will actually be easier and cheaper to produe than CCFL backlit displays.

LED TVs in general use less energy (and are therefore more efficient and economical to operate) than conventional LCD TVs. LED TVs are also thinner and weigh less than LCD TVs and generally create a brighter picture. For those who are environmentally concerned, LED TVs also contain no Mercury or Lead.

The Cabling Industry Needs a Makeover

CIS is Charlotte's 1st Choice For Custom Home ElectronicsIt’s time for the cabling industry to reassess how it approaches marketing to consumers.

I find Twitter entertaining and, at times, almost addicting. This morning a tweet from Production Advice’s Ian Shepherd shocked me with concern for an electronics category that I think is beneficial: cabling.

Shepherd retweeted a blog written by L.A. recording engineer Bobby Owsinski, who blogged about a 2008 Engadget story that asked 12 “audiophiles” to compare an audiophile cable brand with another cabling product. It turns out the other cabling product was a set of coat hangers. The crux of the story is that those audiophiles couldn’t tell the difference between coat hangers and expensive cables.

Adding insult to injury, Owsinski points out the obvious difference between the audiophile community and professional sound engineers that use their listening skills for work by noting, “‘audiophiles’ showed just why they get so much abuse from pros over their so-called “golden ears.”

Monster was the cable manufacturer in question in Engadget’s blind testing, and Owsinski says Monster does make good products; the problem, in his opinion, is with how the products are marketed. “Monster Cable takes some reasonably good cable and markets it in such a way that its perceived value is a lot greater than it deserves to be,” he asserts in his blog. “The problem is that for speaker cable, 12 or 10 gauge zip cord [lamp cable] will work just as well as expensive Monster cable.”

Unfortunately for the cabling industry, Owsinski isn’t alone in his opinion, and websites such as Audioholics.com fuel the public’s disdain for cabling by publishing stories that attack the credibility of many of the cable category’s claims for improved performance.

Like Owsinski, Gene DeSalla at Audioholics points out that Monster and other brands aren’t necessarily bad, its just that their products don’t measure up to the claims.

To rectify this problem, I think it’s time for the cabling category to own up to its self-generated hyperbole and tone it down. Let’s start by addressing the claims of exotic materials, proprietary construction techniques and slick geometry designs that contribute to their out-of-this-world performance claims without any third-party verification.

Manufacturers should look to develop products that are affordable to consumers in these difficult economic times. Too often, critics point to the steep price tags attached to some cabling products and note that a consumer could buy a nice car or place a down payment on a house with the amount of money some companies ask for a pair of speaker cables.

The last thing the cabling industry needs to do is educate the public on the benefits of a properly designed cable that employs quality materials. Owsinski says cabling can make a difference in how a system performs, and I believe he is correct. Using dealers, let’s teach consumers on how to buy cable and how to listen.

One other suggestion I would make is that maybe we should think about locking audiophiles in the basements from which they came. For all their passion about music and equipment, they inflict a lot of irreparable damage to an industry that can hardly afford the scrutiny of a public that doesn’t respect their collective opinions. OK, OK, I’m only kidding about that last suggestion, but I would take away their Diana Krall and Patricia Barber CDs and LPs as punishment for their past transgressions.

Happy New Year To Everyone!

Custom Installation Services - Charlotte's Source For Home Theater!With the holidays and our busier than normal schedule over the past month, it has been a while since I have posted a blog.  So, this will be different than my normal format of product news.  I wanted to post a personal blog to thank all of our loyal clients for your support over the past year.  2010 was a good year for C.I.S., with new product offerings added to our lineup, as well as new and exciting technology trends.  None of which would have been possible without everyone’s continued support!

A new direction for us this year was to “dabble” in more commercial A/V installations.  These included sports bars as well as an overhaul of the video at Lance, Inc.  This has opened up a new revenue stream for C.I.S., and one we will continue as we move forward into the future.  As part of this new commercial business, C.I.S. has partnered with ZEE-VEE, makers of high definition boxes that enable 1080p over coax for long distance runs and combining signals to existing channels for ease of use.

Another new product in our lineup is from SpeakerCraft, with their addition of the “FloBox”.  The FloBox is a single unit that allows you to dock your iPod, iPhone or iPad, play a CD, stream from the internet, access iTunes or listen to FM radio.  Combined with substantial amplification, quality drivers and a sleek, futuristic cabinet available in five finishes, the FloBox will transform any room into a concert hall at the push of a button!

I would like to again thank everyone for your continued support, and to a great 2011!  Stay tuned for more of my traditional blogs with product news and updates!
