How old is plasma technology




















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. Learn more about motion handling. Screen uniformity is another area where plasma TVs win. Since they didn't have a backlight, they could evenly control each pixel. 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. Each of these issues are simply inconvenient for most people. The simple answer is yes, but it doesn't mean you should go out tomorrow and buy a new TV just because you read this article.

If you aren't experiencing any issues with your plasma, then you probably don't need to replace it right away. However, if you notice your plasma is starting to show some signs of permanent burn-in, it's probably a good idea to get a new TV before the burn-in becomes worse.

There could be other advantages if you upgrade your TV, like technological advancements and a higher 4k resolution. Modern TVs come with a built-in smart system, which isn't something that most plasmas had, and this allows you to directly stream your favorite content without the need for an external streaming device.

OLED, which stands for Organic Light-Emitting Diode, is different from plasma, but shares many of the same characteristics, while also avoiding some of plasma's downfalls.

With Panasonic stepping out of plasma TV manufacturing, we anticipate Samsung and LG to do the same even though we have not received official comment from those companies.

It seemed so obvious that we forgot to ask Samsung's F series plasma TV from was the best plasma displays they ever produced. Panasonic's 4K LED TV offering just isn't up to snuff compared to plasma display technology, but it's certainly not unwatchable. A properly calibrated ST60 boasts an amazing picture and was a terrific value for the price. Sharp has really been pushing the limits when it comes to large screen sizes.

Now they are entering 4K territory. Having reviewed and written about Television Technology for over 10 years, Anthony never tires of researching the newest qualitative trends related to the technology.
