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.
OLEDs use self-emissive pixels, but what sets them apart is how the pixels completely shut off, creating an infinite contrast ratio and perfect black uniformity. This is an improvement from plasma because it was never able to reach those perfect blacks. OLEDs also have wide viewing angles and a near-instant response time like plasmas. Sadly, they don't get extremely bright, but they're still better for well-lit rooms than plasma because they get a bit brighter and have much better reflection handling.
Also, OLEDs have the same burn-in risk as plasma, but this only happens with constant exposure to the same static elements, and we don't expect it to be a problem for people who watch varied content. Another advantage for OLED is how thin they are, especially compared to plasma, and they aren't as heavy. LEDs are generally the better choice for well-lit rooms since they still get much brighter, but OLEDs are a fantastic choice for dark room viewing.
There were a few reasons for this, like burn-in issues, low peak brightness, and a thick and heavy design compared to LED TVs. Despite plasma TVs' superior overall picture quality, improved contrast, and very quick response time, it wasn't enough to convince consumers to keep buying them once 4k LED TVs became readily available. If you still have a plasma, it's likely you'll need to replace it within the next few years, and you'll probably buy a new LED TV.

NANO75 When it comes down to deciding, it's always a good idea to take a long hard look at the picture yourself, so that you see with your own eyes what you're getting. Having said that though, some types do offer advantages over others. Here are a few of the advantages and disadvantages of these different HDTV technologies:. Depending on the space you have to put your TV into, the size you choose will make a considerable difference.
The distance between your couch and set will rely on the resolution and size of your TV, as well as the angle it can be viewed from. Don't make the mistake of buying a TV that's too big for your living room! For anything above 50 inches you should look to a plasma TV, as they provide more detail in larger formats.
If you're looking to stick to a budget, both LCDs and plasmas will offer what you're looking for - LCDs for small televisions, plasmas for larger ones. Plasma technology has a built-in catastrophic failure mechanism die to the high voltage needed to fire the plasma cells. Just like a neon lamp. Either the HV power supply or the driver Integrated Circuits will eventually fail.
Also, the burn-in problem hasn't been eliminated, just lessened by shifting the picture around. Persistent static displays, such as menus, will still burn in. Further, plasmas are prone to devfeloping "dead" pixels, appearing as black spots, or even worse, pixels stuck "on", appearing as bright spots. This does not happen with LCDs. Plasmas often look grainier than LCDs when viewed close-up.
LCDs can have pixels made up of smaller sub-pixels, improving the perceived detail. If you buy a plasma, you will be lucky to get 3 or 4 years out of it; as mentioned, the LCD has nothing to "burn out" except the CCFL backlight lamps, which can be replaced. LED backlights are common now, which squashes that problem as well. LED backlighting, especially in the sub-pixel style, has rendered the contrast and Mercury issues moot. LCD TV vs. Plasma TV.
