LED LCD vs. OLED vs. plasma
Apr 11, †Ј If you just want a cheap TV to fill a space, a basic LCD should fit the bill. If you care more about performance and design, an LED set is the way to go. If performance is your highest priority, and nothing else really matters, look for a plasma setЧit's the choice of TV elitists datmetopen.com: Virginia Barry. A plasma TV will come with a different warranty period then an LCD TV, as will an LED. The major thing is being able to recognize the different kind of warranties, and .
Modern televisions have a baffling array of acronyms, formats and tech jargon all designed to promote and explain their features. A liquid crystal display is a special flat panel that can block light, or allow it to pass. The panel is made up of segments with each block filled with liquid crystals.
The colour and transparency of these blocks can be changed by increasing or reducing the electrical current. LCD crystals do not produce their own light, so an external light source like a florescent bulb is needed to create an image. These are far more efficient and smaller in size, meaning the TV can be narrower. These displays are backlit by an array of LEDs directly behind the screen. This enables focused lighting areas Ч meaning specific cells of brightness and darkness can be displayed more effectively.
As the name suggests have lights set around the television frame. Edge-lit models reflect light into the centre of the monitor, and are the thinnest, lightest models available. Since they have fewer lights in the centre of the screen. LED is the most popular format of TV on the market now due to its cost, size and versatility, although it is not the highest quality image available.
Plasma screens are made of 2 sheets of glass with a mixtures of gases stored between the layers. When charged with electricity, what is the length of an 8d nail gases react and cause illumination in the pixels across the screen. In these larger how to get a dba in pennsylvania sizes, buying the Plasma option tends to work out cheaper.
OLED is massive leap forward in screen technology. Without this restriction of an external light source, OLED screens can be super thin and crucially, flexible.
On the whole, OLED is thinner, more flexible, faster at processing images, creates deeper colours and more crisp in contrast. We may begin to see the technology more on phones, smartwatches and wearable tech, where the screens are a smaller size and are therefore more cost efficient.

Jun 11, †Ј You could get a plasma HDTV, a CCFL-backlit LCD, or if you had the money, you could buy an LED-backlit HDTV. Well, now both plasma and CCFL LCDs are . I will suggest you LED TV because LEDs to illuminate the display use less power than any other televisions including plasma TVs which use fluorescent bulbs. so that LED TV is more efficient and saves the buyer money on electrical costs. K views View 1 Upvoter. Feb 08, †Ј If an LED TV consumes СxТ units of power, ideally an LCD and Plasma TV of same dimension will consume С2xТ and С3xТ units of power respectively. Hopefully now you are more clear on .
We purchase our own TVs and put them under the same test bench, so that you can compare the results easily. No cherry-picked units sent by brands. TVs have evolved over the years, and different technologies have come and gone. The TV market in the 21st century has been defined by large technological advancements.
However, not long after, plasma suffered the same fate as its long-forgotten counterparts. Liquid Crystal Display LCD TVs have held the market share of sales since , and companies stopped manufacturing plasmas altogether by Before explaining the differences between each technology, it's important to understand how each TV displays an image.
Plasma TVs contain tiny pockets of gas, and when a voltage is applied to them, they turn into a plasma state.
The voltage then strikes the mercury within the plasma to emit ultraviolet UV rays, which pass through phosphor cells to produce an image. Each pixel in the TV contains three phosphor cells: red, green, and blue, and these three colors combine to produce a color. Essentially, plasma TVs don't require a backlight, and each pixel is self-emissive as it produces its own light.
These are long tubes that are placed horizontally across the screen behind the LCD panel. When the light is turned on, it applies a voltage to the pixels, which makes them rotate a certain way to allow light through and produce an image. When it wants to display black, the pixels are rotated to create an opaque screen so that light doesn't get through.
This is what makes them different from plasma TVs because each pixel isn't self-emitting. It's also important to note LED is simply a marketing term used by manufacturers to describe their backlight. Learn about differences between full-array and edge-lit local dimming. Plasma and LED TVs each present their own advantages and disadvantages in terms of picture quality, price, build, and availability.
It's generally thought that plasma produces a better picture quality due to their superior contrast ratio, but LED TVs became more popular because of other factors, like a lower cost and greater availability. Below you can see the differences in picture quality between two older TVs from It's clear the plasma was better at the time, but LED TVs have also gotten better since then, so picture quality has greatly improved.
Contrast ratio was one of the main advantages and selling points of plasma TVs. Since each pixel emitted its own light, it simply turned itself off when it wanted to display a black image. This allowed the TV to display very deep blacks, but because there was always a bit of charge left in the plasma, it still wasn't a perfect black level. However, technology has evolved to greatly improved the contrast of LED TVs, even to the point where it's also as good as what plasma once was. Still, you won't get a perfect black level, but most modern LED TVs produce such deep blacks that even in a dark environment it looks like perfect black levels.
For reference, plasma TVs had a max contrast of about 4,, according to DisplayMate. Learn more about contrast ratio. LED TVs are a clear winner here, and it's one of the reasons why they surpassed plasmas in terms of popularity. LED TVs get significantly brighter, so they can fight glare from light sources easier. Additionally, plasma TVs had to use glass on their front panel, which caused intense glare if you had any lamps or windows around the TV.
LED TVs can use a coating on their glass panel to help reflect and diffuse light, making it a better choice for well-lit rooms. Plasmas were designed for dark-room viewing, but since most people don't have dedicated home theater setups and often watch with a few light sources around, they weren't that useful. As you can see below, the plasma TV had pronounced reflections, to the point where it's even hard to see the image, and instead you're watching yourself watch TV.
Learn more about peak brightness and reflection handling. This means that the image remained accurate when viewing from the side, which was great for watching sports or a show with a few people. TV manufacturers have tried different technologies to improve viewing angles on VA panels.
Samsung has an 'Ultra Viewing Angle' layer, and Sony uses their 'X-Wide Angle' technology to increase the viewing angles, both at the cost of a lower contrast ratio. It's still not as good as plasma, but they're wide enough for watching TV in a fairly large seating area. Below you can see the differences in viewing angles between a plasma and a VA panel.
These TVs were tested on different test benches , so you shouldn't directly compare the videos, but we included them to give you an idea of how each technology affects the viewing angle. Learn about viewing angle here.
Plasma TVs were great for motion handling, like with sports and video games due to their quick response time. 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. 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.
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. Get insider access. Best TVs. TV Recommendations. View all TV recommendations. All TV Reviews Samsung.
