Q. I know LCD monitor is cheaper then plasma but more LCD have 1080p, right? Which is better? Why there is a price difference? I know LCD is liquad, and?
A. Plasma has better response time so will show movement better than an LSD TV; important when watching action particularly sports. A good LCD has a 5 Milli Second response time where as a good plasma 0.2 MS.
LCD screens are generally much brighter and better suited for rooms the receive a lot of light. Plasma's are better in darker rooms; easier on the eyes.
Generally plasmas are 42 inches or larger. LCDs are manufacured by more companies.
LCDs sometimes are manufactured with pixles that are burned out causing a dot on the screen. Plasmas have problems from screen burn.
I decided after much research to forget about buying a set for another year; I was holding out for 42 - 48 inch 1080 p plasma. A couple of weeks ago Tiger Direct had a 42 inch LCD 720 p set on sale for $699 and I couldn't resist. I am extremely happy because I am getting a great picture, I have all the bells and whistles (PIP, split screen, TV tuner, multi connectors including computer) and I paid a lot less than anything I have seen before or after.
My advice: Get a good inexpensive 720 p that you you like (plasma or LCD) make sure it has an antenna (broadcast hi def is better than hi def on cable or satelitte), and enjoy. 1080 p is more expensive and really only gives a better picture with a Blue Ray DVD (also relatively expensive).
By the time prices fall for Blue Ray machines and discs and more channels are broadcasting in hi def the price of TVs will fall dramatically. Move the set you buy now into another room and get yourself a bigger set
What's the difference between plasma and LCD TVs these days?
Q. I've noticed a few more plasma TVs showing up for sale in stores - considerably cheaper than LCDs of equivalent size and features, so what's the catch?
A. After all, there are so many acronyms and buzzwords to wrap your head around, such as 1080p, 120/240Hz, 24p, HDMI and LED backlighting. Huh?
Along with deciding how big a screen you want (which is usually tied to the size of your budget and the dimensions of your room), the next choice should be between LCD.LCD (LED Backlit) or Plasma — and all have their merits. Here, we'll describe each of these formats, and also point out their shortcomings.
LCD
What is it?
lcd tv 120mhzSimilar to your laptop computer's monitor, flat-panel LCD televisions use a liquid crystal display to produce a sharp and bright picture; these crystals are sandwiched between two panes of polarized glass, which are stimulated by an electric current and illuminated by fluorescent tubes housed behind the glass. Some newer LCD TVs, however, use LED-backlighting instead. LEDs, or light-emitting diodes, translate to a better-looking picture (see photo).
Pros
There are a number of advantages to buying a LCD televisions. For one, with more than three-quarters of all televisions embracing this technology, there is a lot of choice when it comes to manufacturers, models and sizes (13- to 103-inches, in fact). Competition, of course, breeds more aggressive pricing, too, which is good news for the consumer.
Flat-panel LCD televisions are also very thin, light and energy efficient, and are ideal for rooms with plenty of ambient light, which, for example, comes through large windows as they tend to absorb rather than reflect light (reflected light can obscure your view of the screen).
Cons
Until recently, LCD TVs didn't handle fast motion images as well as plasma TVs, resulting in a somewhat blurred image. Newer LCD TVs, though, have added technologies such as 120Hz frame doubling (or 240Hz frame quadrupling) to smooth out motion. It's still not as good as plasma, but much better than before. Also, LCD TVs used to have problems showing dark blacks (because a light was still on behind the pixel showing black, resulting in a more greyish hue). Many LCD televisions today use local-dimming with LED-backlighting (see next section) for improved contrast ratios (whiter whites and blacker blacks) - but, keep in mind, this is not an issue associated with plasma TVs.
LCD (LED Backlit)
What is it? Not a Different Type of TV
led lcd tv backlighting backlitIt’s tempting to think LEDs belong in a completely separate category beside LCD and plasma TVs, but in reality, an LED television is just a type of LCD TV. The proper term would really be "LED-backlit LCD TV," but that always seems to get truncated to "LED TV" in everyday conversation, perpetuating the confusion.
To understand how LEDs function in an LCD TV, think of an actual liquid-crystal panel as the plastic pegs in a Lite Brite. They hold a translucent image, but without a powerful backlight to punch through and light it up like a signboard, you’re not going to see much. On your old Lite Bright, an inefficient incandescent light did the job, but pretty unevenly. On a typical LCD TV, fluorescent lights provide the backlighting through a special plastic sheet called a light guide that distributes light from a fluorescent tube evenly over the surface of the TV. On an LED-backlit TV, fluorescent tubes are replaced with light-emitting diodes – LEDs – the same technology that probably lights up your digital watch, the buttons on your monitor, and the indicators on your stereo. They can be either situated along the edges of the TV like a fluorescent tube, or arranged directly behind the screen in a grid. But what difference does it make, and why would anyone spend so much money on it?
The Benefit of LEDs
The most obvious reason LEDs have fallen into favor in LCD TVs: they’re simply more efficient. Although fluorescent lights do a decent job converting electricity to light in the big scale of things, LEDs perform even better. Typically, manufacturers claim an efficiency improvement of up to 30 percent over fluorescent-based sets, which can add up significantly over the lifetime of a TV, especially on larger screens that use more juice to begin with.
LEDs are also much smaller than tubes, even after accounting for the number of them needed to light an entire TV. That means LED-backlit televisions can be manufactured significantly thinner than their tube cousins. For instance, most of the ultra-thin televisions that measured under an inch thick at CES used LED backlights, because they add very little depth to the profile. Though commercial variants aren’t quite as dramatically thin as these prototypes, they’re significantly skinnier than their fluorescent-backlit counterparts, making them some of the most chic and living-room-friendly HDTVs out there.
For home theater enthusiasts, LEDs only matter for one reason: image quality. Because fluorescent tubes must light the entire screen evenly, designers have no way to vary the backlighting intensity in different parts of the
