What is a Plasma TV?

The main component of Plasma TV screen is plasma gas. These are gaseous cells that can be charged electrically. Once electric voltage passes through them, the plasma gasses emit lights. This process is responsible for rendering screen images.

Plasma TV produces vivid colors and clearer images because its screen pixels carry their own light spectrum.

The Strengths & Weaknesses of Plasma Televisions:

High contrast is one of the strong points of Plasma TV. High color definition due to superior contrast is the best advantage of Plasma TV. It can also display black colors in high definition. There will be no grayish spots on your TV even if the scenes on the screen are totally dark. Because of this, you will be able to see other objects displayed on the screen.

If you love to watch fast paced action movies, racing, and other sports events, then Plasma TV should be your choice. That’s because Plasma TV can perform well in tracking rapid movement sequences.

The biggest weakness of Plasma televisions is its susceptibility to screen burn-in. This problem can disfigure the images in your screen permanently. New Plasma models however use devices that can avoid burn-in problems. Older models of Plasma TVs still suffer from this problem.

What is LCD TV?

The utilization of liquid crystals is the primary mechanism of LCD TVs to generate images. These liquid crystals can receive lights from a backlight source. The crystals will polarize the lights thus rendering different color spectrum. These colors will be transformed into millions of pixels producing clear and highly defined images.

The Pros and Cons of LCD Televisions:

You will not encounter any burn-in problem with LCD TV. This is a highly efficient television because it generates less heat so energy consumption is minimal. There is also a built-in anti-glare function for every LCD screen. So if you like to watch TV in a brightly lit room, then LCD TV should be your best option.

However, LCD TVs have weaker color contrasting ratios compared to Plasma TVs. Its ability to display ultra high definition colors will be limited also. Rendering black colors is also not a strong point of LCD TVs.

The quality of high speed movements can also suffer if displayed on LCD TV screens. LCD TVs have less ability to track fast paced movements. New models however have found ways to solve this problem.

LCD color pixels are also prone to color aging. This is the equivalent of image burn-in on Plasma TV screens. So, when the color pixels of LCD degenerate, you might see some white or black spots on your screen.

You can certainly enjoy watching TV from LCD or Plasma screens. These are the latest TV innovations and they are made to provide you with quality viewing experience. But these TVs also have strengths and weaknesses just like any other device. You have to know what you need in order to choose the best high technology TV.

First, it might be useful to understand why surround sound is so great. It works to make the movie you are watching far more realistic to your senses. Movie editors design the sound to come from different speakers depending on its location and context in the movie. Having speakers all around you allows actors to the right of the screen to sound like they are speaking to the right of you, or for background sounds to sound like they are behind you. They even allow sound to move from one place to another, as with a train that starts off in the distance on one side of you and ends up sounding just like it is roaring right by your ear. In short, surround sound allows the sound to be completely and accurately integrated with the movie you are watching.

If you have already built a home, you can install surround sound by placing speakers around the room. There are a lot of systems designed to do this, with elegant, tall speakers. Many are wireless so you don’t have cords running all over your floor or up your walls. However, building a home from scratch allows for a unique opportunity to embed speakers right into your walls, exactly where you want them. Although wireless home theater systems eliminate the need to run wiring around the room, hiding the speaker body right in the wall frees up even more space in the room. It also allows you to mount the speakers at just the right height to suit your sound preference, without the awkward look of surface mounted speakers.

windows Most of the sound entering the house comes in through the windows. Check your windows and see if there is anywhere that air can come through- those will be points where the sound comes through the most. Seal any of these cracks and gaps with flexible polyurethane or latex caulk. This is a great way to make you home more energy efficient as well! Installing weather strips and storm windows will do wonders for the energy-efficiency of your home as well as make the whole house quieter. Windows that are vinyl-framed and double-paned are best for sound and can be more than twice as strong for temperature insulation!

Doors and Walls

The best way to soundproof your walls is to build them with solid, heavy material to dampen sound traveling through it. Light, flimsy, and hollow materials will not prevent sound from traveling in your home.

If your walls have already been constructed and you’re looking for ways to help dampen sounds traveling through them, there’s still a great deal that can be done. Adding insulation to your walls can help, if it’s done right. Adding drywall is a poor decision, as its rigid material is not strong for sound-dampening and the space behind the drywall can create an acoustic chamber. Make sure that all holes and cracks are covered when insulating- even a small gap will allow noise to enter. Even attics can allow sound into your home and could benefit from proper insulation.

Adding mass to your walls can help as well. If you have one wall facing an especially busy or noisy street, padding that wall with dense material can help. Hollow walls can be soundproofed by adding injected blown foam insulation. Rough surfaces in your room will deaden sound. Acoustic sprays are available that can give texture to your walls and absorb sounds that hit them.

When installing doors, choose heavy, solid-core doors over lighter hollow-core ones. Hollow doors with a space inside are filled with air, which allows sound to travel through with ease. Making your doors airtight will do a great deal for both insulating and soundproofing your home. If you’ve been putting off lubricating those squeaky door hinges, there’s no time like the present to quiet them!

Better Viewing Environment
Believe it or not, complete darkness is not the best way to watch movies. This is in complete contrast to what most people actually do. You can even see this in practice at many movie theaters; the lights along the sides of the theater are kept very dim during the film but they are still on. The dim lighting helps to prevent the eye fatigue that results from staring at a bright light source in complete darkness. If you have ever had a headache after watching a long movie, it may have been caused by eye fatigue.

Atmosphere
Lighting creates a certain atmosphere inside a room. This is true whether or not the atmosphere created is one that you had intended.
Positioning, color, and intensity all play a role in the ambiance home theater lighting produces. Decide on exactly the feelings you would like to produce with your home theater lighting. What emotions would you like to evoke as people walk into your home theater? Warm? Relaxed? While different colors elicit different emotions from different people, there are some colors that seem to be associated with certain feelings. Choose shades of the color that is associated with the feelings you want to elicit from your home theater audience.
The position and intensity of your home theater lighting will be determined by the placement of the viewing screen. Direct lighting should be avoided during the movie. Using fixtures that reflect light off of walls will help to avoid glare while reducing the harshness of the light. Dimmer switches are also a necessity if your home theater room is not equipped with central lighting control. They will provide you with the ability to customize the intensity of your home theater lighting to your own tastes.
