Why LCD Televisions Are the Best - Time to Know

By Sunita Biddu

Who knew that the study of electrodes would one day take over our television screens? Liquid crystals are in reality solids. Temperature keeps them moving at a very high speed making them more like liquids than solids. A little more temperature makes them totally liquid. This technology is what in short is called the LCD.

Understanding the LCD Technology

The LCD technology uses polarized light. There is the lamination of two polarized sheets to glass with liquid crystals. A two breadth lattice of electrodes then allows each pixel in the range to be set in motion individually. This technology is what then makes it possible to see the pictures in your television. This makes the picture more real. The pixel based color system allows for the duplication of the live picture to the closest possible view.

Costs

The LCD provides a solution in getting a balance of price and size as it is cheaper that plasma and other display modes. The wide angle view also keeps them ahead of competition.

If you are in6trested in buying a television that will keep you glued then it is important to note that the best flat screen television shall be both light, and cheap to get your attention. With the fall of large screen production costs, LCD has also ventured into the large screen fields, with their lighter panels making them easy to carry.

The old CRT technology created very heavy televisions that used too much electricity for the bombardment of atoms on the screen for vision not to mention the number of times you would need the interior designer to change the settings for your TV room to fit in your new set!

LCD TVs are light and flat! They do not cost us more electricity in the end. Having one of this creates that extra space in your wallet for self development. These televisions have been in development for a while now, and they have proved to be able to compete with plasma.

Before, plasma held an advantage over LCDs as they could build large screens while LCD televisions were limited to small screens. But recent developments by Samsung, LG and other major brands have corrected that. The Television offers a more converged vision with an ability to fit on any wall in your home.

Other Newbies

Above all, some LCD panels can show two different sets of scenes differently. This allows you to surf two or more channels at a time. With a higher resolution than other displays, you have a clear picture and access to all your favorite television programs throughout the day!

Some companies as Samsung are claiming to have LCDs that can go as much as four times the resolution of other displays! They also have built a wide angle of 180 degrees! This wide view is certainly a selling point for the football lovers that do not want to loose any dome action even when it is their turn to fetch the beers!

Indeed the pace at which LCDs have grown is fast. Embracing this technology will not only give it the edge to develop further, but also provide LCD developers with important feedback that will help improve the development further.

LCD vs. DLP TVs

By Bradley James

Two new technologies in the world of TV, DLP and LCD, are now in a tight competition. Not long ago, everyone was talking about Plasma and LCD - which one would win? It became clear to most that Plasma, with its short lifespan of just 3-4 years, was simply not the best choice. In fact, the LCD screen has several benefits over plasma. For instance, LCD screens run much cooler than the average plasma TV, and thus require less power to operate. Plasma TVs run so hot, in fact, that they require a fan to cool them down – which can be noisy. In addition, plasma screens have a tendency to degrade over time, slowly becoming dimmer. LCD screens, on the other hand, run relatively cool, and do not degrade over time. Some Plasma owners, who have used their TVs for a few years now, have already witnessed the dimming of their screens. Also, LCD screens tend to have overall better picture quality, and are typically 10 to 15 percent lighter than plasma.

Now the choice is mainly between LCD and DLP - two distinct technologies that offer slight differences in display, price, and performance. If you are looking to buy a new flatscreen TV this year, you are probably wondering which one is right for you.

What are DLP, LCD TV Screens?

DLP stands for Digital Light Processing, while LCD stands for Liquid Crystal Display. DLP technology, developed by Texas Instruments, uses a DMD, or Digital Micromirror Device, contructed of 1.3 million microscopic mirrors. Each of these mirrors is essentially a single pixel. When a digital signal enters the DLP system, each mirror is either activated or not, resulting in tapestry of mirrors tilting either towards the DLP light source or away. This process produces different levels of light and dark reflected by each individual mirror. The colors are produced when the DLP light sources run through a red, green, and blue color filter on a moving wheel. Depending on the lightness/ darkness of each mirror, the colors come in an enormous amount of shades, producing vivid color images.

LCD screens are made of several polarized glass panels, between which are liquid crystal molecules. An electric current is run through the crystal molecules, changing their position in respect to the glass. As light passes through the molecules, these changes in angle result in different lightness/ darkness patterns that produce images on the screen. There are usually three polarized glass panels, one with red pixels, blue, and green. This system also produced very accurate, vivid images, but angle is important. You may notice that the best colors in an LCD display are seen straight-on.

Is DLP, LCD TV Screens better than the other?

Simply put, that is a difficult question to answer. Unlike Plasma TV screens DLP and LCD last much are longer, and are considered to both have superior image quality. LCD screens tend to have slightly better contrast, with a larger range of black and white color shades. DLP, however, still has faster refresh rates than LCD (although LCD has been vastly improved in this area over the last two years). This can have implications if you are really into high-action motion (sports, action movies), because movement may seem a little blurred with LCD at times. Also, you'll want to remember that in order for you to get the best color out of your LCD, you have to sit right in front of it. LCD TVs also have a slightly shorter lifespan than DLPs, with only 45,000 to 60,000 hours compared to 75,000 hours or more. As far as price goes, LCD and DLP are still more expensive than Plasma, but like all things in time, their price has been coming down. And right now, DLP is slightly more expensive than LCD, but not by much. DLP, in our eyes, is the best investment, at least for the next few years.

HDTV FAQs

By Nilesh Parab

Bombarded with numbers like 1080p, 1080i, 720p, etc., but confused as to their exact meaning? Not sure which HDTV resolution you should go for? Curious about what HDTV "display" and "source" resolutions are? Then you have come to the right place. Here, you will find clear and concise information about these terms and concepts.

What is Resolution? A Digital Television screen is made up of a grid of dots (called pixels), which light up in different colors to make up the picture which you see on the screen.The number of pixels arranged in each horizontal line is called the Horizontal Resolution of the screen.

The number of pixels in each vertical line is called the Vertical Resolution of the screen. The combined horizontal and vertical resolutions are stated as the Display Resolution or Screen Resolution. For example, if there are 200 pixels in one horizontal line, and 100 pixels in each vertical line, then the horizontal resolution is 200 pixels, and the vertical resolution is 100 pixels. And the Display Resolution or Screen Resolution is written as 200 x 100 pixels. More pixels crammed together in each horizontal and vertical line make higher resolution (or higher definition). Higher resolution makes the picture sharper.What is Scanning? Scanning is the method with which pictures are drawn on the digital television screen. There are two methods of scanning:

- Progressive Scanning (p) - A method of displaying pictures by drawing horizontal lines sequentially.

- Interlaced Scanning (i) - A method of displaying pictures by drawing odd lines first and then the even lines. eg, lines no. 1,3,5...199 are drawn first, and lines no. 2,4,6...200 are drawn afterwards.

Progressive scan gives better picture quality than interlaced scanning. 

It has become common to refer to the Display Resolution by quoting only the vertical resolution followed by the scanning mode letter. eg. 100i means a display with vertical resolution 100 pixels and interlaced scanning mode.

What is HDTV?

HDTV stands for High Definition Television, which is a system whose pictures have vertical resolution greater than 720 pixels. It is implemented by a combination of the following:

- HDTV Sources providing high definition content (eg, TV Channels broadcasting high definition pictures, BluRay DVDs containing high definition pictures, etc) and

- HDTV Displays (HDTV Television Sets) which show those high definition pictures coming from HDTV Sources.

HDTV Display Resolutions

The most common HDTV Display Resolutions found today are:

- 1080p - Displays with vertical resolution 1080 pixels and progressive scanning.

- 1080i - Displays with vertical resolution 1080 pixels and interlaced scanning.

- 720p - Displays with vertical resolution 720 pixels and progressive scanning.

Which is better?

In general terms, the higher the resolution - the better is the picture quality, and progressive scanning is better than interlaced scanning for moving images. So, obviously, 1080p is the best. But even 720p suffices for viewing broadcast television channels, as these are limited to 720p content sources. The real advantage of a 1080p is when you are viewing Bluray Discs, and HD DVD which are 1080p sources.

As with other stuff, your needs dictate what you should buy.

What Goes Into Buying the Right LCD TV?

By Roberto Sedycias

The increasing pace of development in the field of technology has made almost everything compact and compatible for the users. Particularly the electronic devices are improving faster than the requirements of the people.

Every one wants comfort and satisfaction and a good return on their investment in the bargain. The product manufacturers are also competing to give their best so as to make their product acceptable and hence, every time some new product hit the market with some improved technology.

LCD TVs are the revolution in the direction of television technology. The sophisticated technology involved in LCD TV help liquid crystal displays. The advantage of the LCD TV lies in its low power consumption and making it into almost any shape. This is the first choice for people who prefer watching movies in large screens.

The LCD TV with its light weight can be placed anywhere with a stand. The crystal clear images of the device are excellent to give you new dimension to your viewing experience. The impressive features of high resolution make gaming more interesting. The flat panel televisions with bright and attractive pictures and remarkable sound quality are compatible with the HDTV programming.

These days, the price of the LCD TV has dropped. They are gaining popularity for their larger size, better picture, soothing sound, style and light weight. Today, there are larger numbers

of brands available to choose from such as Sony, Samsung, Sharp and Panasonic. However, exceptional image resolution is common to LCD TV of all brands. But while purchasing the LCD TV, there are certain factors that need to be considered carefully to get the best out of your expense.

First of all you need to check the size of the room where you are going to place your new LCD TV. Watching television is a great fun and perfect way to relax in this age. But the rules of watching television include maintaining certain distance from the monitor depending upon its size. Here the size of the monitor matters a lot.

If you are purchasing LCD TV with a larger monitor you need to keep greater distance and for that you need a room with larger space. So your selection of the size of the monitor should be according to the size of the room.

Each frame of images should be refreshed onto the screen. If the refresh time is slow the LCD TV will display poor image quality though it depends on what you are watching. Sometimes it may happen that you can find good pictures during watching movies but not while playing video games. If you are getting fastest response time with a decent price you can go for it.

There are many models of LCD TV in the market that allow connection to computer but lack a DVI connection. If you are connecting your LCD TV to the computer you need to check if the DVI connection is available with it.

Sony KDL-40XBR2 are the most popular LCD TV among all brands. Apart from that Sharp LC-32D44 and Samsung LN-S3251D are also better performing LCD TVs. Do not go for the cheap brands. The better brand names will provide you with high quality hardware. The best way is to browse through the websites where you will find several models with varied features at your display. Check best quality LCD TVs and compare their prices before taking any decision.

An LCD TV is not something that you replace frequently. You must be thinking of a long-term use while purchasing this for your home. Hence, you need to choose the right one. Television is the most popular gadget of fun and enjoyment. The new-age gadgets like LCD TVs are developed with advanced technology for high-end performance. Playing videogames and watching TV are more interesting than it was ever.

Tips For Installing Surround Sound

By Lee Dobbins

If you're installing up a home theater you should seriously consider installing surround sound - otherwise you'll be missing out on a vital part of the home theater experience! Although ordinary speakers will mimic the sounds of the movie, the surround sound speakers will provide greater quality and make you feel as if you're sitting right in the center of the action on the screen.

Good surround sound speakers will come with a digital media port which will provide even more flexibility. This enables you to play music from your iPod, computer, or any Bluetooth equipment. By utilizing this port you can take the audio on these other devices and channel them through the surround sound so you can enjoy the amazing tone and range that

the speakers can generate.

When you are looking for the best in quality sound, keep in mind that you must consider having between 3 to 5 wall mountable speakers and a sub-woofer. Ideally, the best way to place these speakers is to have two front speakers, a sub-woofer, one center speaker and two rear speakers. This way you will have the sound surround system you want.

Installing surround sound speakers can be trying at best, given the excessive wiring on the floor, under the floor (along with the drilled holes that requires) or worming against baseboards, it can be a daunting task. However, you can eliminate all this trouble by buying wireless speakers!

There are additional specifics you may want to look for. For example, if you want to put your center speaker close to the television, buy one that is magnetically shielded; otherwise you run the risk of distorting your image. (Make sure you know before you buy if this is the way you want to arrange your solution.) The sub-woofer you buy also needs to have its own power supply.

Finding the right receiver is crucial for your Surround Sound experience. The ideal receiver will allow you to control movie and music output separately, to plug in headphones and other accessories easily, and has at the minimum a 4-channel Dolby Pro Logic decoder. Additionally, Auto Calibration and Digital Cinema Sound will provide the crispest listening experience. Finally, buy the highest-wattage receiver you can afford.

Installing surround sound is very time-consuming and complicated, so you may wish to get a professional to do the job. Picking the right receiver and speakers is truly the most critical part, so after you have done that, you've won most of the battle.

Home Theater Design Suggestions

By Milos Pesic

 

Planning a home theater design is both exciting and challenging, especially to people who are not so inclined to technical and/or aesthetic matters. Nevertheless, anyone with the budget who wishes to set up a home theater can do so either on his own, with the help of knowledgeable relatives or friends or with the help of a professional. The latter is the easiest way out of home theater design worries but it would cost more.

The first consideration in home theater design is the actual room. Will you be converting your basement or a spare room in the house to a home theater? Will you be using your living room instead? In any case, the size of the room will determine the flexibility and the limitations of your home theater design. Naturally, the bigger the room the more you can do with it. For instance, you can place more seats and even put reclining movie theater seats with arm rests or set up a concession

stand at the back. However, if the home theater is small or if the room is used for some other purpose, then the home theater design should take these factors into consideration.

The home theater room design should identify where each component of the home theater system would be placed. Usually, almost all of the equipment will be placed against the main wall. Try to arrange the seating so that people can stand up go to the rest room, for instance, without being much of an obstruction to the screen.

Furniture placement is also very important to your home theater room design. Where you place your entertainment stand, cabinets, and seats will affect the viewing experience in your home theater. Comfort is important in choosing furniture but so is the right size and shape. The pieces should fit the room and the overall home theater room design accordingly.

Lighting is also important to your home theater design because how you place the lights in addition to the type of light you use will either add to the look that you want to achieve or work against it. Additionally, if you will be setting up the living room as a home theater, you need to plan the layout of the home theater carefully so that light coming from outside through the windows will not reflect on the TV screen. Glare will ruin your viewing experience so you want to reduce or completely avoid this as much as possible in your home theater design.

Whether you opt for a do-it-yourself or professional home theater design, the best way to start your project is to do some research and find out all the design options you have that will work with your space and budget. From there, you can decide which design matches your dream home theater.

Affordable Home Automation Ideas

By Frank Cheshire

Is There A Possibility To Find Affordable Home Automation Equipment?

At first glance the terms "cost effective" and "home automation" don't sound right in the same breath. The reason I say this is not unusual that home automation costs can reach up to a hundred thousand dollars or more. So you are going to be happy to hear what I am about to say.

Please allow me to explain.

It is wise that you do your home work into the various home automation manufacturers lines available before choosing one to invest in. Some of the frugal home automation systems rely on technology that seems to hit and miss at times.

Some of the designer label products have such astronomical programming labor rates that go with them that could reach up to $50k, and thats only for the programming. (Then you need to add in the design costs, home automation equipment purchase, & installation fees.)

Now you can see why I recommend to choose an affordable home automation system that will give you the flexibility to start off with a affordable controller and then add modules to automate even more things down the road.

To begin with why not start off with an all in one remote control for your entire surround sound system. Instead of Putting all

of your money in one of those smart universal remote controls-- 
For just a little bit more you could own a home automation control device, that not only talks with your Television, 5.1 surround sound Receiver, & Satellite Receiver it can look at your DVD & search the web for the jacket cover art & display it on your plasma screen.

Whereas you used to have 22 remote controls you now have one home automation remote that can seamlessly assimilate all of you home theater equipment with a mere push of a button.

Now if you had just bought one of those smart remote controls you would be limited to working surround sound equipment only.

But thats not the case if you had invested in a genuine home automation controller. Your home theater controller will offer you the flexibility to upgrade your home automation functionality as you can afford it. Down the road when you have a few extra dollars set aside to put a little more on your home automation system then you can add something like 4" wi-fi or Ethernet touch screens & keypads.| The best thing though is that you can actually add features like integrating your burglar alarm system, heating and air, distributed audio, and even automate your lights, a little at a time as you can afford it.

One home automation control can now control all of these devices and cause a chain reaction of events to occur with a click of a button.

Imagine this for a moment when you wake up in the morning instead of an alarm clock waking you... you awaken to your favorite XM station, the heat kicks on because the floor will be too cold to walk on, your electric shades open to allow the mornings light to fill your room & your TV comes on with the morning news!

Let that sink in for a minute, an affordable home automation setup that you can add home automation control modules to as you can afford them. This way your equipment can grow with you as you can afford to do it instead of having to settle for less features in a system or having to put off having your home automation system all together.

Finding the Best DVD Recorder 

By Neil Morrical

If you record numerous TV shows and events, odds are that you probably have a considerable amount of space dominated by VHS cassettes. Space savings may not be enough to push you over to get a DVD recorder; however, high-quality DVD recorders have come down in price enough to consider the transition. Not only can you store high quality video on blank writeable DVDs, but the media has come down in price considerably as well.

When DVD recorders were first released, they came onto the market at steep prices. Now you can find name brand DVD recorders that are still quite a deal. Don't waste your time purchasing an off-name brand DVD recorder, when you can get a good Phillips or Samsung for nearly the same price. Most of the off-name brand DVD recorders available today will often provide poor DVD burns, which will result in wasted money on DVD media. The extra ten to fifteen dollars to get a high-quality burner is definitely worth it.

There still are some expensive DVD burners on the market, but they bring something extra to the table. Some of the

leading brands in are manufacturing DVD recorders with built-in hard drives. With the added storage of a hard drive, you can record video instantly, without even loading a DVD to burn. Additionally, if you only intend to watch the show at a later time, you can save the DVD, which you would have burned. If you are considering purchasing TiVo just for short term recordings, you could save some money just by having a hard drive equipped DVD recorder.

Unlike their original predecessors, new DVD recorders are more compact and pleasing to the eye. Now you can get a hard drive equipped DVD recorder, which is roughly the same size as your regular DVD player. The exception to this is DVD recorders, which also contain a VCR, since VCRs haven't become quite as thin as DVD drives.

Something to take into account is the idea of purchasing a good DVD recorder online. Amazon and other online stores have some great deals available on both new and used DVD recorders. Before you spend some extra money, take the time to check out what's available online. In many cases, the shipping is free on larger electronic devices and you can stock up on some cheap DVD media while you're shopping online.

Just in case you're still having some remorse for your older VHS tapes, there's some additional good news. You can purchase DVD recorders with VCRs built in. Benefit from the higher quality recording technology and transfer your old VHS cassettes to DVD. Why throw away recordings of the Dukes of Hazard or Dragnet if you don't have to?

Finally, take into account the fact that most DVD recorders are somewhat easy to operate. If you have family opposing the idea of DVDs simply because they think you cannot record on them, buy them one for Christmas. Older generations opposed DVDs mainly because they thought it was the end of recording your own video. Help out the family and bring them up to speed as well.
