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.

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!

10 Popular Audio Demos
 
 
 

Polk Audio Speakers - Available at Custom Installation Services in Charlotte, NC

Custom Installation Services is Charlotte, NC's #1 Authorized Polk Dealer

Polk Audio shares some of its favorite audio demo tracks.

During a recent visit to Polk Audio, the Baltimore, Md.-based manufacturer gave us a sneak peek at some of its upcoming products.

The speakers were great, and some of the audio tracks were fantastic. As you know, playing the correct tracks during audio demos is essential. It can sometimes make or break a client’s decision.

We recently shared the favorite audio demos and video demos of some CE pros. Now, Polk has shared with us some of its favorite demo tracks and why each works so well.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolinas!Yello | Fat Cry

The opening to this cut is very recessed and almost muffled with a good bass line then not quite 20 seconds in is like someone pulls a veil away and not only does the music become clear & detailed it also expands in size with bass that just says bet you didn’t know I could go this low.

The voices that come in after this are good and catchy but you just want to go back to the beginning to see if you really heard that.

I find this cut to be a very good test of a loudspeakers ability to show off what everyone is always looking for big, powerful, deep bass along with being accurate.  After the first time one has heard this cut, every time thereafter you are waiting, timing the moment that the veil is pulled away and the power of that bass note that arrives with, oh yeah.

CIS - #1 Martin Logan Authorized Dealer in the Carolina'sCantate Domino | Christmas Song

This cut has so much going on and, like Fat Cry, surprises you with its power and emotion as almost every person I have demoed this for over the last 23 years have experienced everything from a chills to tears. In the beginning it appears that the symphony is being played in a small hall or maybe a church along with a soloist as it builds you begin to realize this symphony is in a very large concert hall as the music begins to wrap around you revealing the immense size and height of the hall. This happens with increased volume and now a choir of voices along with a pipe organ.

Custom Installation Services - Charlotte's #1 Authorized Polk Dealer in The CarolinasCantus | She Moved Through the Fair

Excellent recording of acapella. Listen for the air around the voices, staging, and sense of life-like dynamics even (especially) in soft passages.

CIS is Charlotte's #1 Authorized Polk Audio Speaker Dealer in The Carolina'sMahotella Queens | Nomshloshazana

This joyful, upbeat track features layered instruments that are added in the first minute, demonstrating clarity and the ability to separate instruments effectively. Bass is strong and punchy when played on a high quality speaker.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolina'sLyle Lovett | Church

Lyle’s voice is front and center with the expanse of a choir across a broad soundstage behind him. Distinct hand claps and voices as they chime in now and then. Piano intro is early on, then the bass comes in with a full bottom end.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolina'sJohnny Clegg | Akanaki Nokunaka

This is just a great fun, traveling down the road cut with a great beat and Johnny’s amazing voice.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolina'sJohn Butler Trio | Bound to Ramble

There is tremendous separation of instruments. There is enough air that each instrument stars. You hear the attack on the Banjo. The rumbling resonance of the body of the upright and the overtones of the strings.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolina'sKevin Gilbert | Goodness Gracious

This track features an up front vocal that is good for testing lateral balance of system. The solid, driving bass line should be even across frequencies. The shaker in the introduction should be placed properly in space and have a natural sound to it.

CIS - Charlotte's #1 Authorized Polk Audio Dealer in The Carolina'sMighty Sam McClain | Too Proud

Impact and dynamic range of blues-man Might Sam McClain. Listen to the detail of instruments in the background such as organ and percussion. Better speakers resolve these impressively.

CIS - Charlotte's #1 Authorized Polk Dealer in The Carolina'sShawn Mullins | Ballad of Billie Jo McKay

There’s something enjoyable about listening to the basics of a vocalist and his guitar painting a lyrical work of art. This track allow you to listen to the natural sound of an acoustic guitar and feel the emotion of vocalist. Listening to music should invoke passion, or at the least, some type of personal reaction.
