Buy a new TV is not what it was, there are many more options and features to think when the only decision you had to do was the size of the screen. Among the questions most frequently asked these days is: "Should I use an LCD or plasma flat screen TV?", If you want the quick understand the answer, read on.
LCD is clearly the most popular choice these days, selling more plasmas with a good margin. It is on the way to television displays in stores and some misunderstandings about the longevity of plasma "burn-in".
In retail stores, televisions in general in the showroom with many lights, LCD screens and can display more light than the plasma they seem brighter and more attractive environment in this pump. But your living room or home theater room is not a retail showroom, so that this apparent advantage is a bit tricky.
Many people are concerned about the longevity of the plasma, having heard rumors that the gas inside the screen are "loaded" at regular intervals. This is completely false, a plasma TV has never called for "charging". Plasma and LCD today have about the same length of time, more than 60,000 hours, more than 20 years before the TV eight hours a day, seven days a week translated.
Then there is the problem of plasma "burn-in", which are the spectral images on the screen after a static image is displayed for a certain period of time causes. This was a problem with the first generation of plasma, but it is now almost no concern. Yes, you can create static images after some time will be saved, especially when the game is new, but is rarely several methods that most plasma TVs have to fight.
One thing to consider is the energy consumption of the device. Plasma TVs tend to consume more energy than LCDs of similar size, although manufacturers to reduce the gap in modern design. Interestingly, the energy of the plasma, more or less depending on the overall brightness of the image at any time. However, the LCD power consumption is relatively constant. And if the backlight brightness of the LCD, which is generally desirable, in a dark room, you can get even more performance.
So what are the real issues, you should consider this important decision? Ask yourself the following questions.
What will I want to watching?
If you are a viewer of the film seriously, I generally recommend plasma to its lowest level is black and higher contrast of the image more than most LCD lit by a CCFL (Cold Cathode Fluorescent Lamp) backlight. However, more and more of today's LCD TVs use LED (Light Emitting Diodes) instead of the CCFL light source, and these sets can reach very deep blacks with some limitations.
There are two types of LED, LCD display with backlight and side lighting. Equipped because these terms mean, LED backlit sets in a table behind the LCD panel itself, while the models with LED lighting on the side edges of the screen, their light and diffuse through the LCD screen headed by special optical materials.
Virtually all models with LED backlighting offers a feature called local dimming the lights behind the bright areas and reduces dark areas of the LED is essentially a very low resolution, the black and white version of the image, as described above. This increases the perceived contrast and deep blacks, but small bright objects on a dark background, like the stars in space, may be surrounded by a halo, because the size of the independently adjustable LED "zone " is often much the size of bright objects.
As a number of CCFL, LED LCD TV here as side lighting brighten Sony NX810 and can darken the whole screen in a dynamic way, which is seen in better overall contrast and blacks. In fact, LEDs can be adjusted more than CCFL and can be turned off if the entire image is turned solid black as a black screen interstitials between shots in the car or opening credit sequence of screens in Master and Commander. However, you can often see, this process takes place, which can be annoying.
If you want to play many video games on the new flat panel, LCD is probably the way forward. Video games have left too many static elements (box score, scenes of construction, etc.), ghost images on the plasma, especially when they are new. The same applies to certain television programs, especially new channels and businesses with a ticker at the bottom of the screen.
