Advantages and Disadvantages of Plasma and LCD Screens

Prices of HDTV sets are falling rapidly and the experts anticipate that they continue to drop over the next years. Because of this there is a lot of interest in all of the types of TV technologies available right now.

If you are shopping around for a TV right now, you can choose among a large variety of flat screen technologies including Plasma screens and LCD screens. Each technology has its own advantages over the other.

Why choose Plasma?
Plasma screen TV's technology is based on exotic gases that can glow in different colors when different amounts of electric current are passed through them. For every pixel you seed in the Plasma screen there is a small pocket of gas that can be excited individually to glow at different wavelengths.

The result is an incredible range of colors that quickly reacts to changes of the images. Plasma screens re often easier to make in larger sizes than LCD screens and they are better at displaying fast action without blurring. However the do have a number of disadvantages. First of all the Plasma screens consume more than twice the amount of electricity that LCD screens do. Secondly Plasma screens aren't bright enough to function well in higher light levels and their brightness fades with time and use and third they also tend to produce and annoying buzzing sound if they are operating at altitudes in excess of six thousand feet.

Why choose LCD?
Differently than the Plasma screens the LCD screens are based on a special type of crystals that react to electrical current by changing shape (not changing color like the gasses in a Plasma screen). In a normal LCD TV screen, the crystals are arranged in a grid pattern and they are supported by a transparent film transistor. A transparent film transistor applies the current to each individual crystal in the screen and, depending on the voltage that is applied to the individual crystal it will change its shape in various ways to block out light coming from a fluorescent lamp behind it.

The crystals will not only block out light completely to make black, but they will also block out different wavelengths of light to let through different colors. Every crystal represents one pixel on the screen. Compared to Plasma screens the LCD screens have the advantages of being extremely energy efficient and they render a great "crystal clear" picture in a variety of light levels, and lend themselves well to displaying output from computers.

The disadvantages of the LCD displays are that they are slightly blurring when displaying fast movement due to the time that the crystals need to change shape. Secondly the LCD screens are not that good at showing very deep shades of black due to the amount of energy that the crystals need to block out the light completely. Luckily both of these problems are almost unnoticeable as the technology has advanced.

In conclusion
There is not right or wrong choice when it comes to picking either a LCD or a Plasma screen. It all depends on the size your want, the contrast of colors you need and the things (watching movies or using as a computer screen) that you are planning using the new screen for. Always be sure to test the screens before you buy them. You might even be lucky to be able to borrow a screen for a test in your own living room to make sure that it is the right choice.

Everyone Is Switching From Desktops To Laptops

When people talk about laptops, everyone assumes that all laptops are wireless. Traveling with a laptop is easier today than it once was, the laptops have gotten smaller and lighter. The new mobile laptops make computing easy for many people. When purchasing a laptop, make sure a wireless connection is built in so you can reach the internet if you are in a wireless area. The laptop is replacing the big desktop computer; but the mobile computer needs to provide the ability to accept components for expandability. Many people today keep all of the information on their computer, so if the computer goes down many people will not have that data. In today's modern world the laptop or sometimes called notebook is a must have. If you do not have a laptop computer yet, you should know that one of the most important aspects of having a laptop computer is having a great power supply. Every laptop computer needs to be equipped with some type of warranty; the laptop should have at least a one year manufacturer warranty. You may even be able to play movies on them with crystal clarity. Purchasing a laptop computer is not an easy job to do because there are so many important things that should be considered before purchasing.

The type of work you do can affect the screen size and type that is most suitable for you. If you are not worried about graphics a screen size of 12-14" is acceptable. If the work you are doing is graphically intensive than a 15-17" is better. Screen sizes range from 12 to 19 inches. A laptop computer with smaller screen is great option if you do not plan to use laptop too much.

Going from 256MB of RAM to 512MB of RAM will speed up your laptop. If your needs are somewhat mundane - email, spreadsheets, word processing, etc. 512 MB of RAM should be plenty. RAM is to a computer what location is to real estate.

You also need to think about the hard drive in the laptop you are considering. The hard drive is also a very important specification to consider in buying a laptop. The speed of a hard drive is normally calculated in rotations per minute. A hard drive of about 50 gb or over is a good rule of thumb.

In addition to the processor, you will probably want to upgrade your system with memory, monitor, a graphics card or video card, and pointing device and keyboard. Finding cheap components is easy today due to the internet, many sites have popped up and made all of these components accessible. The important thing to remember when shopping for components is that you need to make sure they are compatible with your system.

Laptop cases are an important computer accessory you should make sure you acquire. They have many sections that accommodate important office documents. Another important type of carrying case is the wheeled roller case. But, their safety and protection is equally important. A laptop case is specially made for carrying a laptop but a backpack is just a bottomless pit. Getting a quality bag is very important since you are carrying around an expensive piece of equipment. Your notebook is going to be at least 6 pounds, probably more. The portability of laptop computers is both a boon to busy business people. Your notebook should be sturdy and rugged. Expensive notebooks should be protected properly.
