LCD TVs versus LED TVs

Posted on January 25, 2012 by admin

When it comes to understanding the difference between LED TVs and LCD TVs, the term “LED TV” is kind of a misnomer. So-called LED TVs and LCD TVs both use liquid crystal display (LCD) technology to create the picture—the difference is in the backlight. Your typical LCD TV is backlit by compact fluorescent lighting (just like those earth-friendly CFL bulbs), while an LED TV is lit by LED (light emitting diode) lights (like in stoplights and automotive lights).

Among LED backlit televisions, there are two types of arrangements: edge lighting, which puts LEDs around the edge of the display for thinner construction and full array, where the LEDs are placed behind the screen. Both edge-lit and local array LED backlights can also come with local dimming, which allows the individual LEDs to dim or brighten independently to create higher contrast. Virtually all full array LED TVs have local dimming, and in general, these provide the best picture. Edge-lit LED TVs without local dimming are the most common LED TV.

So, for comparison purposes, you’re looking at three main types of LCD TV backlights: fluorescent (the standard LCD TV), edge-lit LED (usually without local dimming) and full array LED (with local dimming). Here’s how they stack up:

Contrast
Contrast is all about accentuating the differences between dark and light spaces, so naturally, full array with local dimming works the best. Edge-lit LEDs and more recent fluorescent backlit LCDs are tied for second.

Color Accuracy
LED TVs can come with white LED backlights or RGB LED backlights. In terms of color accuracy, you won’t notice much of an improvement over fluorescent LCDs in a LED TV with white LED backlights. But an LED TV with RGB backlights provides much better color accuracy.

Viewing Angle
Viewing angle refers to the clarity of the picture when viewed from the side or from above or below. In general, full array LED TVs with local dimming perform the best, followed by fluorescent LCD TVs and then edge-lit LED TVs. However, a bigger factor is the quality of the glass and any anti-glare features it may have. Higher end TVs will have better viewing angles, simply by virtue of having higher quality parts, in theory.

Refresh Rates and Response Time
The way that TVs handle action and fast movements, such as in action flicks, sports broadcasts and video games, depends on the response time (measured in milliseconds) and the refresh rate (measured in hertz). Backlight technology—such as LED vs. fluorescent—has no bearing on response time or refresh rate, so you won’t see any improvement in capturing action with an LED TV.

Power Consumption
For those of you concerned about going green, your best bet is an edge-lit LED. LEDs consume less energy than fluorescent bulbs. However, full array LEDs with local dimming use far more individual LEDs than edge-lit LED TVs, and for now, full array LED TVs consume more energy than fluorescent LCDs.

Bottom-line
LED TVS are better than LCD TVs in many ways, but don’t focus solely on the backlighting technology. Not all LED TVs are created equally, and a high end LCD TV just might outperform an LED in some crucial departments. Your best bet: comparing them with your own eyes without looking at the specs and decide which you like the most.

LCD TV Cleaning

Posted on January 24, 2012 by admin

Sometimes, an LCD TV could get more than just dust on it, and require cleaning. We discuss some of the ways to clean your LCD TV, LED TV or other big-screen TV to ensure you get a great, crystal clear picture.

A soft, lint-free cloth for cleaning your LCD TV

You don’t need anything fancy aside from a soft cloth, it could also be a microfibre one. The cloth itself is ideal for wiping those stains, marks and dust up. Make it slightly damp as required – and never use paper towels to clean your TV.

LCD Cleaner can be used

Never use a household grade cleaner like Windex on your screen! The ammonia content in the cleaner will damage your TV screen – instead, there are a number of LCD Panel Cleaners on the market you could use, or just plain warm water will do the trick!

Make your own LCD Cleaner

Most commercial LCD TV Cleaners on the market are actually just a mix of Isopropyl Alcohol and Water, which you could mix yourself cheaply in a 50/50 ratio. Just remember that when you’re cleaning your TV, don’t spray straight onto the screen, moisten the cloth instead!

Combining all the above tips will ensure you have a Clean LCD TV ready for watching High Definition Movies, and your favourite media!

Posted on January 24, 2012 by admin

LCD TV Manufacturers have recently put in a lot of effort into the physical appearance of their products. But sometimes, this isn’t enough to match your living room furniture, or your immediate tv viewing area. That’s where different LCD TV Wall Mount solutions can come into play.

There’s a number of creative ways to mount your LCD TV or LED TV onto your wall:

Fixed TV Wall Mounts
Full Motion TV Wall Mounts
Picture Frame Style Cable TV Wall Mounts

Fixed TV Wall Mounts

A fixed TV Wall Mount only allows for limited pivoting of your LCD TV or LED TV against the wall; height and horizontal alignment remain fixed in a spot on the wall. Fixed TV Wall Mount solutions are best suited to larger screen televisions.

Full Motion TV Wall Mounts

Styled similarly to a mechanical arm, Full Motion TV Wall Mounts extend the range of motion available to a TV off the Fixed TV Wall Mounts by allowing adjustments in vertical and horizontal positioning on the wall for your LCD TV. This type of mount is most suitable for Smaller, lighter-weight TVs.

Picture Frame Style Cable Wall Mounts

Using an elegant cabling solution based on Artwork systems in many galleries around the world, Picture Frame Style Cable Wall Mounts offer a discreet mounting solution that’s both non-intrusive, aesthetic and simple to use. With systems capable of holding larger screen TVs as well, this solution looks spectacular when paired with a very thin/light and slim form-factor LCD TV or LED TV.

Watch out plasma TV, LCD TV is racing ahead.

As the years go by, technology advances and LCD TVs only become increasingly better. Last year an LCD TV exceeded a plasma as your favourite screen of the year.

Not only are customers now receiving a better quality LCD TV, but much better value for their money. The prices for LCD TVs keep dropping, so now finally distributors can truthfully say that an LCD TV does give you value for your money.

Not so ago we were once thrilled with a 32 LCD or an 37 LCD TV, as plasmas ruled the 40 inches and over screens. However, now LCDs offer a “40-plus inches feature a 1080p resolution full HD tuners.” Some feature LED backlighting, which create better results with colours and smart TV in some form. And if LCDs haven’t already gone all out there enough… Playback in 3D has become increasingly popular! Wouldn’t that just be a lovely evening with the family… Sitting around your LCD TV with big 3D goggles on.

What more would you want? So if you are looking at purchasing a brand new TV maybe it’s time to browse the net just to see how low LCD TV prices have really gone. You wouldn’t want to miss out on this technological breakthrough would you?

What is an LCD TV?

Posted on October 17, 2011 by admin

When searching for an LCD TV most people don’t even know what an LCD stands for.

To keep it simple LCD stands for:

Liquid

Crystal = LCD

Display

An LCD screen is a flat display. It uses technology in its LCD display that is shaped like rod molecules that flow like liquid and bend light. These molecules are the liquid crystals inside these LCD TVs. An LCD monitor is displayed in front of a light source or reflector to exhibit images in colour or monochrome.

LCDs are very energy efficient and only require external lighting (the crystals) that is situated behind the LCD panel to produce a visible picture. The more the molecules are twisted, the better the contrast and viewing angle.

LED LCD TVs are now appearing more frequently in televisions. LCD LED work by backlighting the entire LCD panel or by collaborating a set of red, green and blue LEDs to illuminate a small cluster of pixels. This improves contrast and black level.

LG LCD

LCD displays are used for a wide variety of technology situations. These can include computer monitors, televisions aircraft cockpit displays, signage, telephones, calculators etc. They are usually compact, lightweight, portable, less expensive, more reliable and easier on the eyes.
