Chose The Right Tv !

Author: Marc Crohn

Quite unlike the conventional CRT TV that came in limited sizes and had to be accommodated in a specific way, flat panel LCD TVs and rear projection televisions can be wall mounted or placed on the floor, depending on space available. Select the right TV based on the size that will fit in your room.

LCD Wall Mount and Floor
A flat panel LCD or plasma TV can be hung on the wall, after considering viewing position. If it is a heavy TV it might not be a good idea to try to fix it on the plaster directly. A wall mount TV is suitable when you have sufficient space.
Suppose you don't have the wall space to wall mount your TV, go for an LCD or plasma TV with a stand. Rear projection TVs can also be freestanding and are less expensive than LCDs and Plasma TVs. Your rear projection TV can come in huge sizes like 70 inches and it can even come HDTV ready. Their weight is similar to plasma TVs though the technologies differ.

Big Screens
The general choice when choosing big screens is between flat panel plasma TVs and the more affordable rear projection DLP TVs manufactured by Toshiba, Panasonic, Samsung, RCA and Mitsubishi. Screen size starts from 42" and onwards. The technology used is digital light projection, producing images that have deep blacks for good contrast. To watch these TVs, you'll need to sit in such a way that you are directly in front of your TV to be able to experience the best picture in terms of brightness and contrast.
Rear-projection LCDs on the other hand are thin and light with great picture quality. The pictures however, tend to be dark at times and the black reproduced by them is not the best black. Rear Projection CRT is considered yesterday's technology bigger and bulkier sets. Picture quality can be better than even LCD or DLP televisions in high definition rear projection CRT sets.

Get The TV That Fits Your Room
First, measure the spot where you want your TV. Get the length, depth and width. Home entertainment systems need empty space on either side as well. Remember, your TV need not fill the entire area. To maximize space usage, decide on the right screen size. Different screen sizes suit different rooms. So, if you have a small room, flat panel LCDs in the range of 15 to 21 inches or CRT tubes TV in the same size range, portable TVs and combos that include TV, DVD, VCRs are ideal. If your room is narrow, consider a rear projection TV or a flat panel LCD or plasma television. Big rooms can take larger sized LCD TVs, rear projection TVs, and wide screen plasma TVs.
What used to be a matter of just making a decision on price range while buying a Television set has now become a challenge, making a decision between different kinds of technologies. While price and size still make all the difference, picture quality has come a long way with DVD quality and high definition signals in the market. You need to look at whether the picture quality you saw at the retailer's store is the same when you view the TV in your home.

Have You Seen LCD Projection TV?

Author: Bivan

Have you seen LCD projection TV? No, really. I don't just mean
a picture online or in an advertisement on a normal tube
television, but have you actually seen projection TV? It really
is completely different that what even the hardest of hardcore
couch potatoes have ever witnessed. It is impossible to properly
describe the effect of LCD projection TV, but roughly it is to
normal TV what the CD is to the cassette tape. Leagues of
difference, I say. It is the bee's knees, the cream in your
coffee, the sprinkles on your donut, the...aw, enough. Let's
cut to the chase.
Big yet sleek and impressive without ostentatiousness, Toshiba
has a pair of outstanding 42" LCD projection TV sets to draw the
consumer's eye. The featured Toshiba LCD TV, the 42" LCD
projection TV, is but one representative of the "Diagonal Cinema
Series" bunch. Just under thirty-five hundred dollars (see
Toshiba.com for ordering information), this 42" LCD TV comes
replete with Toshiba's "adaptive LCD projection TV technology,"
which makes feasible the addition of innumerable extensions to
this LCD projection TV, thereby allowing all your favorite
doodads all the benefits of it, up to and including Dolby-based
sound systems.
Speaking of sound systems, have you heard the Sony projection TV line? No, I mean have you really heard of it? Well, it's Sony and that right there says a lot. Audio has been at the heart of Sony business since time immemorial (okay, the 1950s to be precise), thereby levering projection TV sets against the competition as in other audiovisual fields.
Sony product information promises that their products will be
at center of a complete audio "suite." Stuff like Focus
technology, TruBass and SRS 3-D dot the T's and cross the I's
of the projection TV experience. It is said that good sound
can save an average movie, but poor sound can ruin a great
movie. If one of the prime selling points of LCD projection
TV in general is the technology's presentation of movies,
Sony LCD projection TV should be a must on any serious TV
shopper's priority list. See Sonystyle.com for the entire LCD
TV line, not to mention a tantalizing description of SRS WOW
technology; you can rest well assured that this will warm
the movie goer's cockles.

How Does An LCD Screen Work?

Author: Gray Rollins

LCD screens are uniquely modern in style, and the liquid crystals that make them work have allowed humanity to create slimmer, more portable technology than we've ever had access to before. From your wrist watch to your laptop, a lot of the on the go electronics that we tote from place to place are only possible because of their thin, light LCD display screens. Liquid crystal display (LCD) technology still has some stumbling blocks in its path that can make it unreliable at times, but on the whole the invention of the LCD screen has allowed great leaps forward in global technological progress.

Although liquid crystals are not really liquid, their molecules behave more like a liquid than they do like a solid, which earns them their name. The crystals in an LCD exist in a kind of a unique middle ground between solid form and liquid form, which gives them the movement and flexibility of a liquid; but can also let them remain in place, like a solid. Heat can quickly melt a solid to liquid, allowing it to move, whereas cool will make the liquid solidify almost instantly. The sensitivity of liquid crystals to temperature can be an advantage, or a disadvantage. It allows for the highly successful use of liquid crystals in devices like thermometers, where temperature responsiveness is a boon; but this same property can unfortunately make LCD screens unreliable in extreme climates.

In an LCD screen, electric currents work at a microscopic level to control the amount of light that passes through the liquid crystal molecules that make up the moving layer of the screen, which is sandwiched between clear glass panels. The currents can force the naturally twisted molecules to unwind or coil tighter, thereby changing the amount of light that can pass from the bulb behind the glass to the eye of the viewer. It may help you understand this process by imagining that light filters through an LCD screen the same way that sunlight filters through the leaves of a tree. Now, imagine that the tree is being blown in the wind, and you will see that the amount and placement of the light that comes through the leaves changes. This is very similar to the dynamic that powers an LCD screen, except that the sun is a small light bulb, the leaves are molecules of liquid crystal, and the wind is made up of electric currents sent by the computer and designed to create a specific light pattern that your eye will interpret as words or images.
