The LED backlight screen has been displayed frequently in the market currently. This screen is the application which developed slowest among the three application of LED backlight. It is predicated that the permeability of LED backlight screen could not reach one percent in 2009, but it will increase to thirty five percent in the year of 2012.

The technology of LED backlight has been applied for the screen very early. But the product has not gained the good sales achievement, because it had the shortage of color homogeneity and the price is high. The value of the LED backlight becomes more and more obvious with the development of the light source technology. Many manufacturers are joining the development of the related screen, and releasing their own products. Many top manufacturers are also applied this technology into the display. Although many corporations are arranging the LED backlight products, their core business has not turned to the screen. Price is still the main obstacle.

The panel developers hold the optimistic attitude toward the related screen research. Some experts say 2010 will be the year which the related screen starts popular. Most of the screen cost is come from the liquid crystal panel. A liquid crystal display needs dozens of LED which will cost thirty to sixty US dollar, while the cold cathode fluorescent light only costs a dozen of US dollar. The cost reduction of dozens of US dollars will have a large influence on the screen market. The large production of the LED panel will reduce the cost of LED. Some manufacturers are developing the cheaper model group, even some of them declaim that the price of LED model group will decrease to the price of cold cathode fluorescent light model group.

The LED screen will not be popularized widely in the short time from the cost point of view. It is predicated that the price of LED will decline from the large production in the latter half of 2010. It is predicated that thirty five percent of the display panel will apply the LED backlight model group in the year of 2012. The related integrated circuit is P4KE13CA.

The television market continually changes. This year has brought the release of the first 3D televisions on sale. This is shortly after the release of LED technology for televisions. Before discussing the available LED TV bracket and LED TV wall bracket choices one must first understand the LED television. What is it and what makes it different from your typical LCD television?

LED is a type of light which has been around for several years. The light bulb has a longer life than your typical light. The first thing we saw light emitting diodes with was Christmas lights. Samsung, Panasonic, Philips, Toshiba, LG, ProScan, and Vizio have all decided to offer LED TVs. The technology has replaced the traditional fluorescent light found in LCD televisions. LEDs have two forms: a Dynamic RGB and a White Edge LED. The RGB method provides truer colours like black, white and primary colours. It has a higher dynamic and costs less. The Edge LEDs have a diffused light across the entire screen sharpening the backlight, but also causing a dimming of the picture.

As you might have guessed by now the LED technology is nothing new. The use in televisions was new and it rose in popularity rather quickly. The reason they became so popular was because most understood the LED light would last longer than fluorescent light for the backlighting. They figured it was better technology and therefore worthy of spending a little more. The downside in the popularity of LCD televisions is that the off angle viewing is poor. Even offering LED with the LCD technology has not changed this. However, LCD is still better than the plasma design because it is based off of light rather than a plasma creation which has a half life.

At the moment the LED technology has not quite reached its potential, but for those who follow the electronic industry this has not made them less popular. In 2010 more models have been released in small screen sizes. LG has over four models you can purchase as do many of the aforementioned producers of LED technology.

Now that you have an understanding of what LED televisions are and that they are being sought by the public you can look at the LED TV bracket and LED TV wall bracket available for these televisions. As a flat panel screen this TV can be tipped over and damaged if it is not correctly mounted to a wall with the TV bracket.

LED TVs are not unlike the regular LCD with fluorescent light. You can use similar TV brackets with the LED television. However, it is best to shop for an LED TV bracket or LED TV wall bracket. The reason for this is that you have the right size. You always want to have the proper bracket no matter the television you own. Therefore, you can look at the two choices you have. You have the TV bracket which is standard in how it works. It will mount your television safely to the wall or TV stand you have chosen. It will not have a lot of manoeuvrability when it comes to the tilt or swivel. It is mostly a steady wall mount for direct angles.

The second choice you have is the ultra slim bracket. The ultra slim bracket comes in two ranges: 26 to 32 inches and 37 to 65 inches. They were created for this range because up until 2010 small sized LED TVs were not being manufactured. Now you have some companies offering below 30 inches.

The ultra slim bracket is not like your typical LCD television bracket. It offers four screws for the smaller size screens, but it is in a horizontal position rather than a square. There are two silver brackets for screws and then two black brackets. You can manipulate the size a little bit on the ultra slim bracket. It is not a huge metal bracket, which makes it lighter and to some degree easier to install.

For those who require an LED TV bracket the ultra slim can be the most attractive. It will be a little more than the regular LED TV bracket which is designed like most LCD brackets. The good attribute of LED TV bracket options like the ultra slim is that it can make the TV almost flush with the wall like a picture frame.

Okay first the bad news. The new LED HDTV sets are great and you are going to want to get one if you take a good look at the picture. So if you are considering looking at LED technology I suggest you stay away from the big box store if you intend to exercise some restraint. They look that good!

But there are also a few warnings about the most recent technology out on the market which of course is 3D HDTV. Now, I’m not going to lie to you here. 3D is a really cool technology and it looks incredible but after hearing a few of my colleagues complain about headaches and dizziness I started to look a bit deeper. Turns out there are some warnings you may want to know about.

I’m not overly hung up over this because I plan to get a 3D TV and use it for regular Blu Ray Discs – not 3D Blu Ray. I plan to see how many reports of weakened vision and accidents from watching 3D TV first – just to be safe. Read on…

These warnings are published on Samsung literature and accompany your 3D HDTV set when unpacking your unit.

3D LED HD TV Warnings – LED TV review report from Samsung Warning Labels:

• “Children and teenagers may be more susceptible to health issues associated with viewing in 3D and should be closely supervised when viewing these images” Samsung said on its website.

• “Some viewers may experience an epileptic seizure or stroke when exposed to certain flashing images or lights contained in certain television pictures or video games.

• “If you suffer from, or have a family history of epilepsy or strokes, please consult with a medical specialist before using the 3D function” Samsung says.

• It’s not just those who are already aware they might have problems that are at risk though.

• “Even those without a personal or family history of epilepsy or stroke may have an undiagnosed condition that can cause photosensitive epileptic seizures” said Samsung.

• “Pregnant women, the elderly, sufferers of serious medical conditions, those who are sleep deprived or under the influence of alcohol should avoid utilizing the unit’s 3D functionality.

• “Viewing 3D television may also cause motion sickness, perceptual after effects, disorientation, eye strain and decreased postural stability”

• Samsung are recommending that viewers take frequent breaks from watching 3D TV in order to lessen the potential effects.

• “If your eyes show signs of fatigue or dryness or if you have any of the above symptoms, immediately discontinue use of this device and do not resume using it for at least thirty minutes after the symptoms have subsided”

Maybe I’m just psychotic but frankly I’m not real concerned about these warnings. I don’t plan to watch 3D TV all day, every day. I just want to use it when watching a movie once or twice a week at the max. My total exposure to TV is maybe 2 hours every 2 weeks. I suppose if you planned to watch the news in 3D you may (or could) experience more severe problems.

Like everything else including watching television… ALL things in moderation folks! You should not drink gallons of alcohol in one sitting and you probably should not watch 6 hours of TV everyday either.

As Americans we usually don’t know when to quit. It is estimated that the average teenager watches 4 hours of TV everyday. What a total waste of time… You can raise your kids however you like, but you are personally responsible for their ability to contribute anything useful to society. Sitting in front of the TV 4 hours a day or even 1 hour in my view is ridiculous. We need to find something useful to occupy our minds and entertain our children.

I think the above warnings are probably issued for Americans. (yes, I am an American) Now, I love American, I love this country, and I love what it was founded on. So when Samsung puts a warning in their HDTV boxes about excessive use of 3D HDTV it makes me wonder who the warning was intended for. And I think the finger is pointing at US.

Why should You get a 3D HDTV anyway?

Emerging technology indicates that the tech field is going to keep moving at a very fast clip. Even if you never used the 3D technology available on the set you purchased if you buy a 3D TV you have the capability. The prices are a bit more -but if you plan to spend a couple grand on a set whats a few hundred dollars more?

And, when you are ready to upgrade to a 3D blu Ray Player you won’t have to buy a brand new TV set. So, to me it just makes sense to plan ahead.

My LED HDTV picks – Highest Quality sets at Top, Moving Down to Budget sets at the Bottom; These are non 3D HDTV set picks:

Samsung UN55B8500 $4000: – sets the bar high for all HDTV sets to beat. The buck stops here. Awesome everything! The big Samsung has local dimming on the LED’s and incredible color. Phenomenal HDTV set! (Not cheap!)

LG 55LH90 around $1800 online: This set is much less expensive than the Samsung UN55B8500 model and it is nearly as good. This is my favorite HDTV out of this group and for the money – you can’t go wrong here! But if you have the big bucks go for the Samsung above. The big LG is very tough to beat at this price point.

Samsung UN46B8000 $2000 online: (Amazon) offer incredible black levels and performance. A good price for this unit.

Samsung LN46B750 $1350 online: (Amazon) This set is not an LED but a typical LCD. However, you may be hard pressed to notice. This is a great conventional back-lit model and worth every penny.

Samsung LN40B650 $1000 online and is a good value set that outperforms most sets in this price range. This little Samsung is very hard to beat at this price.

LG 37LH30 $700-$750 online: This budget 37 inch HDTV does not have a perfect picture due to uneven screen brightness and black levels but performs very well within its price constraints.

Vizio VO320E $500 online: 32 inch budget display is a great Vizio LCD TV with good overall picture quality. If used with a decent blu ray player provides a convincing HD picture on a budget.

Vizio VA19L around $200: 19 inch budget display has a great image and would work well for a kitchen, bedroom, or patio set.

These are all regualar 2D HDTV sets. The 3D sets are being tested now and we will have our results out soon. If you are in the market for a 2D set one of the above HDTVs should work great for you.

The HDTV scene is changing so fast it is difficult to keep up with all the advancements. I have always felt that a purchase should be made when the technology matures a bit. I do plan to get a 3D HDTV but I will probably wait a little while. If you must get a set and are not concerned with 3D the sets listed above are highly recommended not just by myself but all over the web.

As always enjoy your Entertainment!
