A High Definition Television, Flat Screen Tv, whether Lcd or Plasma now gives Viewers the best picture possible, the picture from these Tvs are so clear that while watching you can nothing else but see a person's blemishes, pores, teeth color, scars and fine wrinkles and other fine details. Many citizen are shopping around for one of these high tech marvels and they want to make the right decision and maybe this guide will help.
There are some factors to consider
Here is a list of the High Definition formats and how manufacturers label them.
720p or 720x1280 - 720 lines progressive scanned
1080i or 1080x1920 - 1,080 lines interlaced scanned
1080p or 1080x1920 - 1,080 lines progressive scanned
The "i" in 1080i stands for interlaced and the "p" in 720p and 1080p stands for progressive, the interlaced format draws lines onto the screen first odd lines then even lines at 1 /30 of a second. The progressive scan format draws the lines all at once, this variation in the formats may or sound like a big variation but it is barely noticeable.
The way they rank High Definition signal formats, 720p and 1080i are much the same in whole resolution while 1080p is the best, but while 1080p is the best. There are still no 1080p signals of High Definition Television being broadcast, there is simply to much data to transmit, so most High Definition broadcasts are done in 720p or 1080i.
Plasma and Lcd Televisions, are both 4" or less in thickness.
A Plasma Television is a flat panel Tv, inside it consists of cells filled with xenon gas, each cell is like a little florescent bulb, when the gas is charged at specific intervals it strikes red, blue and green phosphors within the cells giving off light in the form of color, each cell is called a pixel, these pixels are sandwiched in in the middle of two layers of glass, there are somewhere in the middle of 800,000 and two million tiny pixels.
Plasma Tv's have great color accuracy, high variation ratios and are good for displaying darker colors like black. Plasmas have a fast response time this means watching sports, performance and video games are ideal on this Tv. The Plasma Tv's are only ready in larger sizes more than 32". They are bit heavier than the Lcd Tv, Some say they have a tendency to "burn in" an image onto the screen, if the image is left on for a long period, but this is a debatable topic now with the newer generation of Plasma Tvs, it is also said that the Plasmas uses more power than the Lcd this may be the case on larger Tvs 50" and over, but in the 40" range the power consumption would be about the same. Plasma Tvs are rated to last at around 60,000 hours, this is equal to 20 years if the Tv is on 8 hours a day 7 days a week.
An Lcd Tv is a flat panel television that utilizes much the same basic Liquid Crystal Display technology that has been in used for some years in other products which display visual data such as calculators, cell phones and computer monitors except to achieve the color display it is much more complicated. Lcd panels are made of two layers of a glass-like material, which are polarized, and are "bonded" together. One of the layers is coated with a polymer that holds the personel liquid crystals. Electrical current is then passed through personel crystals, which allow the crystals to pass or block light to create images.
Lcd televisions have a brighter picture than Plasma Tv, they display whiter whites but cannot display the blacks that the Plasma Tv can, the reason is that when the light "blockers" are "on" in the Lcd Tv some light still gets through and you will see a very dark "gray" on the screen whereas with the Plasmas the pixel is off and you see the the black. The response time is not as fast as a plasma Tv and because of this you may consideration some trailing or shadowing of the image when watching sports, playing video games and watching performance movie genres, however I understand they have come out with a 120 hz and now a 240 hz technology for the Lcd Tv that will fully turn or overcome this, currently Lcd s are running on 60hz, 60hz means 60 cycles per second in alternating power source.
Lcd Tv s are lighter in weight thus easier to wall mount, they have no "burn in" and will last as long as a Plasma Tv.
If you want to watch a true 1080p High Definition picture watch a Blue Ray movie on a Blue Ray Player.
Many Television and Satellite Providers are now Broadcasting in the the High Definition format which as mentioned above is 720p or 1080i
Which one is better? I think it's pretty close and I think it's almost a matter of option and you have to decide what medium you will be viewing most often, the size of room and the lighting in the room.
I personally own a top of the line 52" 1080p Lcd mostly because the Sun shines into my south facing window in the late afternoon, but if you are into video games and sports you may want to consider Plasma.
