Plasma TVs are usually having a less life span of about 20,, hours only compared to the LED TVs as their expected life span is around Plasma TV is the television display where the screen of the TV is illuminated by the use of gas diodes or cells present at the back of the screen. These gas cells plasma cells are light up when electricity is passed through them. They consume more power and are cheaper.

Log in ». LCD screens are still popular both for household and commercial use. However, not all TVs are created equal. So, keep this in mind when buying or hiring your LCD screen — make sure it suits your purpose. These liquid crystals allow light to filter through when electricity is passed through them. The crystals do not produce light on their own however — there are millions of fluorescent lights at the back of the screen to produce the light, as well as shutters to control the passage of light through the liquid crystals.

Since each pixel had to retain a certain charge at any given moment, it was ready to display an image almost instantly. This meant fast-moving scenes looked crisp and smooth, with no motion blur behind them. However, for LED TVs, it can be a toss-up; some lower-end models have a slow response time that causes motion blur, while other high-end TVs have a really fast response time.
Some LED TVs also use Pulse Width Modulation to dim their backlight, and this causes the backlight to flicker, which may create image duplication in fast-moving scenes.
This can be particularly annoying, especially if you're watching sports with fast-moving content. However, the refresh rate depends on the content, and since most content doesn't go past frames per second, having a higher refresh rate TV isn't very useful.

LED TVs can suffer from uniformity issues, like darker edges or Dirty Screen Effect in the center, because the backlight output may not be even across the panel.
However, this is only really noticeable when watching content with large areas of uniform color, like a hockey or basketball broadcast, or if you're going to use the TV as a PC monitor. It shouldn't be noticeable with other types of content, and since uniformity can vary between units, you shouldn't worry about it too much. Learn about gray uniformity here. One of the reasons plasma TVs didn't last too long at the top of the TV world is because of their risk of temporary image retention and permanent burn-in.
Plasmas lose their brightness over the years, and in the worst case, would have permanent burn-in with certain colors staying on the screen, as you can see here.
Even after watching content with static elements, like the news, for an extended period, the outline of the static elements would stay on the screen for a few minutes after changing the channel. These problems are particularly annoying, especially if you watch a lot of TV. There was no way to help reduce this issue, and after a few years, depending on how much you used the TV, your plasma would need replacing.
LEDs don't suffer from this same permanent burn-in, so you won't have to worry about replacing your LED TV down the line because of burn-in. Learn more about image retention. Plasma TVs tended to be heavier and thicker because the panel itself was larger. Although plasmas were the first flat-screen TVs available at a consumer level at the end of the 20th century, LCD TVs quickly became even thinner, easier to package, and lighter to carry from the store to your house.
Plasma TVs also required a lot of power to work and tended to get very hot. With the growth of environment-friendly consumer practices, it became clear LED TVs would win out since they required a lot less electricity, and in a way were better for the environment.
Both plasma and LED TVs were made with larger sizes, but LED had a slight advantage because they were also made in displays smaller than 32 inches, like with monitors. Plasma TVs weren't made that small. This presented a major advantage for LED TVs, as a higher resolution helps create a crisper image, and this essentially was the nail in the coffin for plasma TVs. LED TVs surpassed plasma sales in , and they haven't looked back since. There were a few other problems that contributed to the decline of plasma TVs.
First of all, plasma TVs didn't work at high altitudes because of the change in air pressure with the gasses inside. They would create a buzzing noise, and the image wouldn't look the same, so this could have been problematic if you lived at a high altitude. LED TVs can be used at any altitude; you shouldn't use them in extreme cold or extreme heat, but this is standard practice for any electronic, and temperature is easier to control than your altitude.
Also, plasma TVs emitted a radio frequency that could have interfered with other devices around, like if you had a radio in the same room.
