LCD HDTV - How To Enjoy The Right One

In an LCD TV or "transmissive" display, a light source shines through a panel of liquid crystals in order to display an image. A white diffusion panel behind the LCD redirects and scatters the light evenly to provide a more uniform image than most competing technologies.

The LCD face consists of two transparent layers which polarize a liquid crystal layer sandwiched in between. The front layer of glass is etched with a grid pattern on the inside surface to form a template for the liquid crystals. Liquid crystals are rod shaped molecules that bend light in response to an electric current; the crystals align so that no light can pass through. Each crystal acts like a camera's shutter, either blocking light or allowing it to pass through. A pattern of transparent or dark crystals forms the image. This same technology has been around for awhile, even in such unsophisticated items as digital watches.

LCD TVs use an "active matrix" LCD; the most advanced type of LCD. The active matrix design is based on TFT, or thin film transistors. These are tiny switching transistors and capacitors that are arranged in a matrix on a glass substrate, they switch the LCD pixels on and off. In a color TV's LCD, each color pixel is created by three sub-pixels with red, green, and blue color filters.

One of the biggest challenges for LCD TV manufacturers has been speeding up the pixel response time, (how fast an individual pixel's color can change without blurring) so that fast moving images don't exhibit motion lag or "ghosting". This is especially critical for larger-screen LCD TVs, or for LCD TVs on which much of the viewing will be HDTV, or DVD movies.

An important difference between LCD technology and Plasma is that an LCD screen doesn't have a coating of phosphor dots; LCD TVs color is created through the use of filters. This keeps image burn-in from being a problem--- which is good news in-particular for people who might use a video gaming system or PC on their TV. Another benefit of owning an LCD TV is the energy efficiency of this technology. LCD TVs typically consume 60% lees power than comparably sized tube-type, direct-view TVs.


How To A LCD HDTV

Everybody requires quality and low priced LCD HDTV (liquid crystal display high-definition television) and all LCD HDTV producers say that their televisions are both of superiority and low priced. So does that mean every LCD HDTV out there is worth purchasing? How will a buyer select the right LCD HDTV? Well the answer is, it all depends on what you want .Are you going to use it to play video games or an alternative computer monitor or just only to view television programs? When you are eager to purchase your first HDTV take a big breath and loosen up. You will need a cool head to select between all kinds of LCD HDTV that are for sale.

All right, let's begin. A few things to search on an LCD HDTV are it's max resolution, color depth, and refresh rates. The bigger the figures the better. First is the maximum resolution. Modern LCD TV market primarily provides 720p and 1080p resolution. Nevertheless, if you want the maximum definition, that would be 1080p (1920x1080). You will see this resolution more and more being a standard on monitors, but it will come with a larger price tag. You will be able to see the difference in image resolution between a 720p TV and a 1080p TV. So, do not waste your cash to buy cheaper and eventually lower resolution televisions just to become disillusioned with it in a few months and then dig out your wallet again to buy a 1080p HDTV.

The next thing to consider is the color depth and refresh rates. You'll want the greatest conceivable color depth and refresh rates. High color depth intends that the pictures will have unaffected colors. Red looks red, green looks green, black look coal black rather than dark grey and white looks virgin white rather than light yellow color. High refresh rate is particularly detectable when you're viewing fast movements either in motion pictures or video games. The high refresh rate permits the image transition appearing fluent.

And so, now that you have the resolution, color depth and refresh rates done, it is time to consider the other facets for example the loudspeaker. The inbuilt loudspeakers you will notice in a LCD HDTV commonly have acceptable quality. And so if when purchase the TV, it is probably best to go to your local television store and hear to the audio. Ask the salesman or woman to hook up a DVD and play a action movie and listen for yourself. If you are not really certain what a great loudspeaker should sound like then you should read the online reviews about the televisions. Studying from other people experience and thoughts can make your purchasing decision a good deal easier.

Additional things you might prefer to think about before purchasing is the television design (will it fit in the design of the room you are placing the TV?), whether it has a inbuilt Digital Tuner (so you are able to make the best of the brand new Digital broadcast signals), is there a wall mount included (so you will be able to hang it on the bedchamber wall) and other accessories. They might not be all that significant but you certainly want to obtain the biggest bang for your buck right?

In most ways that really matter there isn't much difference between LCD TVs and Plasma TVs. Both of these highly popular types of flat panel TVs are thin enough to be placed virtually anywhere, and both produce images that are startlingly clear, sharp, and bright. The most notable difference is screen size. The majority of LCD TVs have a screen size measuring 30 inches and smaller. Plasma TVs are, for the most part, uninhibited by measurement restrictions.

Basically, LCD and Plasma TVs are different approaches to the same result because the both create superior images using radically different technology.
