Flat screen TVs whats the difference between LCD,PLASMA,LED and what models are best?
We are looking for a flat screen TV preferably 1080p good contrast any type of models that we should be looking at in particular?? We also have a ps3 Ive heard theres certain tvs that the picture will stick on the tv eventually….and my bf is worried about the refresh rate on the lcd tvs….help please!!!
Answer:
okay. Plasma tv's are a little less common. LCD is the most common and best for the price. Plasmas run hot therefore use a little more energy. LED is by far the nicest but they are expensive but are very cool, thin, and use very little energy. as for refresh rate, 60Hz is usually standard. i do moderate gaming on my LCD tv that has a 60Hz refresh rate and i don't have a problem much with picture lag. However 120Hz maybe a better investment if your a serious gamer. Also there are 240Hz refresh rate tv's which for the price difference between 120Hz and 240Hz i certainly wouldn't buy one. But i have used a 240Hz refresh rate tv and it no doubt has a nice picture…its just alot of money for a tv. Google some of the different ones you had in mind and read about them.
contrast and refresh rates go for LED or plasma, but since
you game get a LED , I seen 32 inch samsung LED's for
around a 1000 or a 47 inch LG 240hz LED at 1800 bucks,
I would definately chose LED, because it has way better
picture than LCD and with plasma picture is almost even
but plasma is bulky, uses lot's of heat, uses more power,
and if you game too much you can get burn in .
Plasma is best but since the screen is made from glass there is glare. so if its in a lighted room where light will shine in that spot go with lcd.
led is backlit.
In terms of picture quality from best to worse.
Plasma. Best contrast. Smallest screen size is 42” (107cm). Panasonic is the world leader in plasma panel technology. The technology is still evolving and improving. Plasma panels have an antiglare coating applied to the front of the screen which significantly cuts down on glare. When it comes to large screen sizes 50” and larger plasma comes out cheaper than LCD. Very fast response time typically 1ns (nanosecond), which is 0.001ms (milliseconds). You can get image retention, which can last for hours before disappearing but only with an abnormally excessively high contrast setting. Burn-in is permanent and that only happens if you leave a high contrast bright still image on the screen for hours. Plasma TV’s normally have an automatic screen saver so after just a few minutes of leaving a still image on the screen the TV drops by a large amount the brightness and contrast thus protecting the screen from damage. With a “normal” viewing setting and a correctly adjusted contrast setting image retention or burn-in won’t happen. Avoid watching letterboxed content only for many hours straight without some full screen viewing in between. Higher power consumption than LCD. Heavier than LCD. Must be transported upright to prevent damage.
LED LCD. Came into being mid 2009 by Samsung. Price on these is still dropping rapidly because at initial release they were VERY over priced. Two types are around edge lighted LED LCD and dynamic LED LCD. In a normal LCD TV cold cathode fluorescent lights around the edge of the screen provide the backlight. The light is then diffused behind the LCD via a diffuser. In an edge lighted LED LCD the light is provided by LED’s (Light Emitting Diodes) instead of the fluorescent lights, the only advantage this type of TV has is that it is thin. In dynamic LED LCD the LED’s are behind the LCD and small sections of these LED’s can be dimmed giving a deeper black in that area. The disadvantage is lost image detail and you can get a halo effect around the dimmed area.
LCD. Mature technology. Fastest response time is 2ms. This is fast enough because the human eye can’t see any difference below 8ms. They have the worst contrast ratio.
With LCD that includes LED LCD you can get defective pixels even when purchased new so check out the manufacturer’s policy on defective pixels before purchase. Some unlucky people have purchased a LCD TV only to find some defective pixels and getting told they have to live with it.
When determining a TV’s picture quality capability it is best to do so with a Bluray DVD because free to air TV including the HD channels is very poor quality video.
