Shopping for a new TV is like wading through a never-ending pool of tech jargon, display terminology, and head-spinning acronyms. It was one thing when 4K resolution landed in the homes of consumers, with TV brands touting the new UHD viewing spec as a major marketing grab. But over the last several years, the plot has only continued to thicken when it comes to three- and four-letter acronyms with the introduction of state-of-the-art lighting and screen technology. But between OLEDs, QLEDs, mini-LEDs, and now QD-OLEDs, there’s one battle of words that rests at the core of TV vocabulary: LED versus LCD.

LED and LCD: Together forever

Despite having a different acronym, LED TV is just a specific type of LCD TV, which uses a liquid crystal display (LCD) panel to control where light is displayed on your screen. These panels are typically composed of two sheets of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid, it causes the crystals to align, so that light can (or can’t) pass through. Think of it as a shutter, either allowing light to pass through or blocking it out.

Since both LED and LCD TVs are based around LCD technology, the question remains: what is the difference? Actually, it’s about what the difference was. Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs. For those interested, we’ll go deeper into backlighting below, or you can move onto the Local Dimming section.

Backlighting

Three basic illumination forms have been used in LCD TVs: CCFL backlighting, full-array LED backlighting, and LED edge lighting. Each of these illumination technologies is different from one another in important ways. Let’s dig into each.

CCFL Backlighting

CCFL backlighting is an older, now-abandoned form of display technology in which a series of cold cathode lamps sit across the inside of the TV behind the LCD. The lights illuminate the crystals fairly evenly, which means all regions of the picture will have similar brightness levels. This affects some aspects of picture quality, which we discuss in more detail below. Since CCFLs are larger than LED arrays, CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

Full-array backlighting

Full-array backlighting swaps the outdated CCFLs for an array of LEDs spanning the back of the screen, comprising zones of LEDs that can be lit or dimmed in a process called local dimming. TVs using full-array LED backlighting to make up a healthy chunk of the high-end LED TV market, and with good reason — with more precise and even illumination, they can create better picture quality than CCFL LCD TVs were ever able to achieve, with better energy efficiency to boot.

Edge lighting

Another form of LCD screen illumination is LED edge lighting. As the name implies, edge-lit TVs have LEDs along the edges of a screen. There are a few different configurations, including LEDs along just the bottom, LEDs on the top and bottom, LEDs left and right, and LEDs along all four edges. These different configurations result in picture quality differences, but the overall brightness capabilities still exceed what CCFL LCD TVs could achieve. While there are some drawbacks to edge lighting compared to full-array or direct backlight displays, the upshot is edge lighting that allows manufacturers to make thinner TVs that cost less to manufacture.

To better close the local-dimming quality gap between edge-lit TVs and full-array back-lit TVs, manufacturers like Sony and Samsung developed their own advanced edge lighting forms. Sony’s technology is known as “Slim Backlight Master Drive,” while Samsung has “Infinite Array” employed in its line of QLED TVs. These keep the slim form factor achievable through edge-lit design and local dimming quality more on par with full-array backlighting.

What is local dimming?

Local dimming is a feature of LED LCD TVs wherein the LED light source behind the LCD is dimmed and illuminated to match what the picture demands. LCDs can’t completely prevent light from passing through, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture. This is accomplished by selectively dimming the LEDs when that particular part of the picture — or region — is intended to be dark.

Local dimming helps LED/LCD TVs more closely match the quality of modern OLED displays, which feature better contrast levels by their nature — something CCFL LCD TVs couldn’t do. The quality of local dimming varies depending on which type of backlighting your LCD uses, how many individual zones of backlighting are employed, and the quality of the processing. Here’s an overview of how effective local dimming is on each type of LCD TV.

Full-array and direct local backlighting

TVs with full-array backlighting have the most accurate local dimming and therefore tend to offer the best contrast. Since an array of LEDs spans the entire back of the LCD screen, regions can generally be dimmed with more finesse than on edge-lit TVs, and brightness tends to be uniform across the entire screen. Hisense’s impressive U7G TVs are great examples of relatively affordable models that use multiple-zone, full-array backlighting with local dimming.

“Direct local dimming” is essentially the same thing as full-array dimming, just with fewer LEDs spread further apart in the array. However, it’s worth noting that many manufacturers do not differentiate “direct local dimming” from full-array dimming as two separate forms of local dimming. We still feel it’s important to note the difference, as fewer, further-spaced LEDs will not have the same accuracy and consistency as full-array displays.

Edge lighting

Because edge lighting employs LEDs positioned on the edge or edges of the screen to project light across the back of the LCD screen, as opposed to coming from directly behind it, it can result in very subtle blocks or bands of lighter pixels within or around areas that should be dark. The local dimming of edge-lit TVs can sometimes result in some murkiness in dark areas compared with full-array LED TVs. It should also be noted that not all LED edge-lit TVs offer local dimming, which is why it is not uncommon to see glowing strips of light at the edges of a TV and less brightness toward the center of the screen.

CCFL Backlighting

Since CCFL backlit TVs do not use LEDs, models with this lighting style do not have dimming abilities. Instead, the LCD panel of CCFL LCDs is constantly and evenly illuminated, making a noticeable difference in picture quality compared to LED LCDs. This is especially noticeable in scenes with high contrast, as the dark portions of the picture may appear too bright or washed out. When watching in a well-lit room, it’s easier to ignore or miss the difference, but in a dark room, it will be, well, glaring.

OLED vs. QLED

As if it wasn’t already confusing enough, once you begin exploring the world of modern display technology, new acronyms crop up. The two you’ll most commonly find are OLED and QLED.

An OLED display uses a panel of pixel-sized organic compounds that respond to electricity. Since each tiny pixel (millions of which are present in modern displays) can be turned on or off individually, OLED displays are called “emissive” displays (meaning they require no backlight). They offer incredibly deep contrast ratios and better per-pixel accuracy than any other display type on the market.

Because they don’t require a separate light source, OLED displays are also amazingly thin — often just a few millimeters. OLED panels are often found on high-end TVs in place of LED/LCD technology, but that doesn’t mean that LED/LCDs aren’t without their own premium technology.

QLED is a premium tier of LED/LCD TVs from Samsung. Unlike OLED displays, QLED is not a so-called emissive display technology (lights still illuminate QLED pixels from behind). However, QLED TVs feature an updated illumination technology over regular LED LCDs in the form of Quantum Dot material (hence the “Q” in QLED), which raises overall efficiency and brightness. This translates to better, brighter grayscale and color and enhances HDR (High Dynamic Range) abilities.

And now to make things extra confusing, part of Samsung’s 2022 TV lineup is being billed as traditional OLEDs, although a deeper dive will reveal this is actually the company’s first foray into a new panel technology altogether called QD-OLED.

LCD vs LED TVs – Which One is Better?

LED-vs-LCD? Lately, choosing a TV has become like walking into a candy store. There are so many TV technology options to choose from, and each of them seems just as good.
Then there are the technical terms to deal with, such as LED TV, LCD TV, QLED TV, UHD TV, OLED TV, and more. You might feel like you need to be a tech pro just to watch your favourite TV show in the evening or enjoy a game with your friend.
However, the confusion comes in deciding whether to go for an LED TV or LCD TV screen. The two might seem similar in name, but they are worlds apart.
Many individuals are switching from LCD TVs to LED TVs. The reason for the switch lies in the innumerable benefits LED screens offer.
Here at Dynamo LED, we offer both LED and LCD TVs, and we appreciate the benefits of both TVs. Be sure to check out our buying an LED Display guide for more info.
In this article, we explain the difference between LED and LCD TV technology and which is better.

LED vs LCD Technology

The main difference between an LED and LCD monitor comes from the display technology used to create the picture displayed.

First, an important thing to understand is that the LED (Light Emitting Diode) monitor is an improvised version of the LCD (Liquid Crystal Display). This is why all LED monitor is LCD in nature, but not all LCDs are LED monitors.

LCD technology revolutionized monitors by using cold cathode fluorescent lamps for backlighting to create the picture displayed on the screen. A cold cathode fluorescent lamp (CCFL) is a tiny fluorescent bulb. In the context of this article, LCDs refer to this traditional type of CCFL LCD TVs.

LED monitors took the old technology a step further by replacing the fluorescent bulbs with LED backlight technology. And OLED (organic light-emitting diode) technology improves it even further by eliminating the need for backlighting.

Direct View LED (aka LED Display)

Early LED monitors had the LED lights placed on the edge of the monitor, called LED edge lighting. However, monitors have changed since then.

Now, LED monitors are direct-view LEDs. Direct view LEDs go a step further and replace the entire screen with an array of LEDs.

This turns a single monitor into a modular assortment of countless light-emitting diodes. Additionally, this expands how big the monitor can be without blowing up the cost exponentially.

The quality of direct-view LED screens is measured by pixel pitch. The pixel pitch is the distance between two adjacent LEDs on the display. The smaller the pixel pitch, the better the quality of the image.

Is LED or LCD Better?

To answer the question ‘which is better- LED or LCD TVs?’, we need to evaluate them on various factors that make a display better or worse.

Let us go through these factors one by one and understand which technology wins in each criterion:

Energy Efficient

Since LEDs replace fluorescent bulbs with light-emitting diodes, LED TVs are more energy-efficient than LCDs. A 32-inch LED TV screen consumes 10 watts less power than the same size LCD screen. The difference in power consumption increases as the size of the display increases.

Size

Light-emitting diodes are considerably smaller than fluorescent lamps used in LCD monitors. Fluorescent lamps have a considerable thickness, but the thickness of diodes is next to none. Moreover, countless diodes are assembled in the same plane, so the thickness of the array isn’t increased no matter how many diodes are present.

Therefore, an LED panel is thinner than an LCD panel. On average, an LED screen can be one-third the thickness of an LCD screen of the same size.

Viewing Angle

Edge-lit LEDs have a slight drawback in viewing angle compared to LCDs, because of the position of the light source. However, direct-view LEDs offer a better angle for viewing than LCDs as the light source is evenly spread on the screen.

Response Time

This is the time it takes to shift from one colour to another. Response times are generally measured in milliseconds (ms). The shorter the time to respond, the better the quality of the images produced.

Typically, LED TVs have shorter (better) response times than LCD screens.

Contrast

Since LED displays use full-array LED backlighting rather than one big backlight, LED TVs offer significantly better contrast than LCDs. LCD backlighting technology only shows white and black, but LED backlighting can emit the entire RGB spectrum, thereby providing a deeper RGB contrast.

Which Lasts Longer, LCD or LED?

If you wonder which display will last longer, this debate is also won by LED displays. LED televisions have a longer lifespan of 100,000 hours on average, compared to 50,000 hours provided by LCD televisions.

Is LED or LCD Better for the Eyes?

An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.

Maintenance

In an LED display, a lot of smaller diodes are used and if a diode is damaged, it can be replaced. In an LCD, you will need to replace the entire bulb in case of damage. Therefore, an LED display is easier and cheaper to maintain than an LCD.

Cost

Since LEDs are a better and newer technology, the price of an LED display is higher than an LCD. However, this is only when we are considering the purchase cost.

When you consider factors such as lifespan and maintenance, an LED display turns out to be cheaper than an LCD one in the long run.

Which Has Better Picture Quality – LED or LCD?

The picture quality of an LED display is far better than an LCD. Due to modular light-emitting diodes, an LED screen produces better control over the contrast, rendering a clear picture. Also, LED provides RGB contrast, which can show truer blacks and truer whites.

Not to forget, they provide a shorter response time as well. Both of these factors result in LED displays having a better picture quality compared to LCD displays.

Which is Heavier, LCD or LED?

Since LED displays are considerably thinner than LCDs, they weigh considerably less. On average, an LED screen weighs about half of an LCD screen of the same size.

Summary

3.1 Pros and Cons of LCD

Pros Cons
  • Cheaper
  • Old Technology
  • Inferior picture quality
  • Costlier maintenance
  • Shorter Lifespan
  • Bulkier

3.2 Pros and Cons of LED

Pros Cons
  • Superior picture quality
  • Cheaper maintenance
  • Long-lasting
  • Slimmer and lighter
  • Better viewing angle
  • Value for money
  • High price

Why LED is Better Than LCD

As you might have noticed by now, LED wins the battle with LCD without any doubt. This is because LED displays have an advantage in all the factors that matter when considering a purchase, except price.

Even when you consider the price, you will find that while LED technology is costlier, it provides better value for money in the long run. This is because of the longer lifespan and easier maintenance of LED screens.

Therefore, if you are considering buying a display for yourself, you should go for an LED display without second thoughts.

Conclusion

The LED is often regarded as a third-generation display. It meets the demands and preferences of the new generation very much.

They are more attractive too. With the increasing shortage of space in new residential complexes, what better solution than an ultra-thin LED display giving a cinematic experience in the comfort of your home.

LED screens are the first choice among the public today, across generations. All are opting to switch to LED from LCD to make their lives more enjoyable and better.

Frequently Asked Questions

Which is better LED or LCD (LCD)

Before buying a new TV, many buyers are wondering which technology is better. Most often, you have to choose between the already classic LCD TV, which is also called LCD, and LED TV. However, before deciding which one is better, you need to know what each of them represents.

  • 3 Types of lighting in LED screens
  • 4 Why LED TV is better than LCD

LCD TV, or as we call it, LCD, has a monitor made of liquid crystals and has a back fluorescent backlight, for which a cold cathode lamp is used.

LED TV contains semiconductors, which themselves are sources of radiation, when voltage is applied to them. As a backlight, LEDs are used, which can be located on the sides of the display or behind it around the perimeter.

What are LCD TVs

LCD monitor consists of two transparent plates with electrodes, between which are liquid crystals. Changes and image transmission occurs when an electric current is applied to the electrodes. This technology itself is not capable of emitting light, so it needs additional backlighting of the screen.

A cold cathode fluorescent lamp is often used as this backlight. It consists of horizontal cathode-ray tubes that are placed along the monitor.

LED TV technology

LED TVs differ from LCD versions only in backlighting, the screen device itself does not differ. For such TV models, there are two types of backlight:

  1. Side (Edge). With this type of illumination, the LEDs are located on the side of the screen, and the light from them is directed to the end of the panel. This is the cheapest technology. In this case, diffusers provide uniform illumination of the screen, and compensation of light losses occurs due to the installed reflectors.
  2. Rear (Direct) light. In this case, the LEDs are located on the back side of the glass over its entire area. Compensators and diffusers are also provided in this technology for uniform illumination and loss compensation. It is believed that this type of backlight is much better than the side.

Thanks to the second type of illumination, each diode, when voltage is applied to it, starts to glow in a certain color and creates the necessary shade of the pixel corresponding to the image on the screen. Thanks to this, the contrast and brightness of the image becomes much better than standard LCD TVs can convey.

Due to the use of LEDs, LED TVs are thinner than LCD models with cathode ray tubes for backlighting. At the same time, models with side illumination are thinner than those with backlight, although they convey contrast and black depth a little worse.

Types of lighting in LED screens

Also, the backlight in such TVs is divided into multi-colored and white. White backlight in its characteristics resembles the backlight in classic LCD monitors. To create it, a blue light source is used, which is covered with gray, resulting in a white color. Such light sources are located on the sides of the screen. Thanks to this lighting, the screen will render the green tint especially well. However, some older TVs with white backlighting may have too much green.

Multi-coloured backlighting is located behind the screen and is able to reproduce colors and shades much better, since red, green and blue diodes are used to create it. With this type of illumination, there will be no problems with a large amount of green.

Why LED TV is better than LCD

Compared to LCD models, LED TVs have a number of advantages. Let’s deal with each of them separately.

Color and shade accuracy All displays of the ICE type, in comparison with LCD screens, have the most accurate reproduction of shades and colors. This is achieved through the use of RGB LEDs. They are able to reproduce the brightest and most saturated colors
Black level and image contrast In LCD TVs, liquid crystals simply block the passage of light to create black. However, a small amount of light still penetrates through them, so it is difficult to achieve special black depth or contrast using this technology. In this case, light diodes can either receive no voltage at all, and, accordingly, do not glow, or emit very weak light. Due to this, the contrast, as well as the saturation of the black color, is better in them.
Energy efficiency LEDs can glow very dimly, while they use a small amount of energy. In LCD TVs, the voltage level is always the same, so LED TVs consume less electricity and reduce the amount of electricity consumed.
Viewing angle This setting is dependent on many technologies, but primarily on the front glass of the monitor. Modern models of LED and LCD TVs are capable of reaching both vertical and horizontal viewing angles of 180 degrees. But old LCD TVs had a viewing angle of only 45 degrees, but LED models had a better viewing angle and started at 160
Durability Fluorescent lamps have a shorter shelf life than ordinary LEDs, which means that the LED screen will last you much longer.
Environmental Compared to LCD models, these TVs do not cause any harm to the environment, as they do not contain mercury, which is present in conventional backlight lamps.
Body thickness Since diodes take up much less space than fluorescent lamps, it is possible to create thinner and more compact TV models.
Lots of options In modern models of LED TVs there are a huge number of different interfaces and connectors, thanks to which you can connect any digital device, game console or even a computer to them. In addition, these TVs support a huge number of audio, video and photo formats, they can have the Smart TV function, as well as 3D.

LCD monitors are trying to catch up with LED devices, and so far they have succeeded only in diagonal size and responsiveness. Their only significant advantage is their low price. However, every year the cost of LED models also starts to show, which means that soon they will also equalize in this parameter.

What is the difference between a plasma TV and an LCD TV and what should I choose? — magazine LG MAGAZINE Russia

When it comes to choosing a new LG TV, many buyers do not know which device is better to choose: a plasma model or an LCD model. To figure out which of these TVs is better, you should know what each technology is and compare their characteristics. Consider the difference between an LG plasma TV and an LCD TV, and which one is better to choose.

LG TV Plasma Matrix is ​​a collection of miniature fluorescent lamps that glow when current is passed through them. Each pixel of such a matrix is ​​a capacitor with electrodes, consisting of three light bulbs with ionized gas. When the cell is activated by an electric charge, one of the lamps glows, emitting light of one of the three primary colors of the matrix: blue, green or red. The dots of a plasma TV produce their own light and are therefore called radiant displays. The speed of changing color rendering and the order of operation of the lamps is at least 400 Hz, this frequency exceeds the speed of LCD matrices, where black pixels are added to improve this parameter.

Plasma benefits:

  • Deep black.
  • Natural colors.
  • Wide viewing angles.
  • Short response time.

Disadvantages of a plasma TV panel:

  • Due to the not too strong brightness, it is better to watch TV and a movie on it in a shaded room.
  • After 20 thousand hours of use, the brightness may decrease by 2 times.
  • Large panel weight.
  • Restriction in dimensions. The Plasma TV cannot be smaller than 32 inches and larger than 65 inches.
  • More energy costs.
  • The device is heating up.
  • Does not work at high frequencies.
  • The screen sometimes mirrors as it is more reflective and susceptible to ambient glare. Therefore, we recommend buying models with an anti-reflective coating if you opt for a plasma panel.

As for LCD TVs, they can be divided into two main groups according to the technology used. Previously, LCD only meant screens that used fluorescent lamps to illuminate pixels. Nowadays, LED TVs are being used more and more. They work on the same principle, but LEDs are used instead of fluorescent lamps.

An LCD TV is a matrix of pixels containing red, blue and green liquid crystals. Under the influence of voltage, the pixels of the matrix change their location, pass or block the backlight. LCD crystals do not produce light themselves, they are called transmissive. Therefore, they need an external source, which can be of two types:

  • fluorescent;
  • LEDs act as an external source.

Depending on which source is used, different types of LCD screens are obtained. The modern market offers three leading LCD TV technologies, each of which differs in the principle of operation and cost:

  • LCD is the first type of LCD panel. Its difference lies in low cost and a simple set of functions. Currently, such TV models are considered obsolete. Illumination in such devices is carried out using fluorescent lamps.
  • LED panels are improved LCD models based on LCD, but with higher clarity and resolution. LED models are equipped with LED backlighting, while the LEDs can be located in the end part or evenly distributed throughout the matrix. At a cost, an LED TV is more expensive than an LCD TV, but the image quality will be higher.
  • OLED is LG’s latest technology. The difference between OLED technology and LED is that OLED devices do not need additional display backlighting, which takes the picture quality on the TV to a new level. The price of OLED TVs will be higher than the previous types, but OLED TVs are of high quality and the TV diagonal can be more than 55 inches.

General advantages of LCD TV:

  • High image contrast for LED and OLED models.
  • LED backlight makes the image as close to natural as possible, with a natural variety of colors.
  • The brightness of the screen during device operation is independent of the ambient light.
  • Less energy consumption.
  • LCD TV does not overheat.
  • Longer display life than plasma.
  • Reasonable price.
  • LCD TVs are lighter and therefore less costly and labor intensive to transport. Light weight allows you to easily mount them on a vertical surface.

LCD Disadvantages:

  • Not deep enough blacks.
  • Medium color and contrast.
  • Decrease in brightness over time.

Disadvantages of LED displays:

  • High price.
  • Uneven illumination.

Of course, picture quality is a key criterion when choosing a TV. Many users are wondering: which of the devices is capable of providing the best picture quality, and what is the difference between the image of a plasma and an LCD panel? Image quality is largely dependent on the backlight. Plasmas are better able to cope with dynamic scenes. There is no blur effect. This is especially noticeable when watching movies or while playing games on the console. Plasmas have an impressive viewing angle. This suggests that if you move a little away from the edge of the device, the image will still be as clear as possible. The picture does not change depending on where you watch the movie on the TV.

In terms of brightness and contrast, Plasma displays feature blacks that are as deep as possible, as well as sharp and vibrant color images that look equally bright when viewed from any angle. LCD TVs have LED backlighting, which makes colors appear paler and the darkest tone dark gray. Plasma models feature a vibrant and vibrant color palette. Plasmas are able to reproduce much more different shades, which is so important for broadcasting a lively and rich image. As an exception, the latest models of LCD TVs with OLED technology, in which there is no LED display backlight, can be considered. If you prefer films with a lot of special effects, you should get a plasma. On the plasma panel, you can observe the same quality image from any viewing angle.

The answer to the question of which TV is better to buy, plasma or LCD, largely depends on the room in which it is going to be installed. If it’s a private room like a home theater with subdued lighting, it’s better to buy a plasma. It will provide a high quality image. The disadvantage will be high power consumption and the price, which is higher than the old LCD models. For living rooms where you can watch TV around the clock, including during the day, LCD TVs are more suitable. The disadvantage of the LCD model can be attributed to the viewing angles, which are not large enough.

Also important when choosing a TV is the screen resolution. Plasma TVs with high resolution do not yet exist. The difference between the LCD screen is that it has a better resolution, since it is easier to reduce a pixel than a cell with gas. LCD TVs with 4K resolution first appeared in 2013. The number of points in such models is 4 times more than in the old Full HD 1080p format. Therefore, image clarity and detail will be much higher. The refresh rate has increased from 50-60 to 100-120 Hz, as a result of which the viewer’s eyes get tired less. The disadvantage of 4K and 8K models is their high price. But with the development of these technologies, the number of OLED TVs will increase, and their cost will decrease.

The functionality of each screen type varies by model. The set of options and capabilities is almost the same, but at the same time, liquid crystal models will still be cheaper than plasma ones.

Consider the difference between the characteristics of a plasma panel and an LCD TV:

  • Screen size. LCDs have a larger assortment: from small kitchen models to billboards. The maximum diagonal reaches 100 inches or more.
  • Contrast. Plasma panels convey contrast better, as they can emit light on their own. In liquid crystal models, the contrast depends on the intensity of the glow and crystals, and this does not allow you to achieve the same level of contrast as in plasma.
  • Brightness. The brightness in plasmas is high, but has limitations. In conventional LCD LCD TVs, the brightness is lower than in LCD models with LED backlighting.
  • Black depth. Plasmas have better black depth as each pixel can glow separately. In LCD TVs, if the picture is quite dark, some parts of it will disappear.
  • Viewing angle. Plasma screens have a viewing angle of up to 180 degrees in all directions. Older models of LCD TVs have a viewing angle of 45 degrees, but in modern models it reaches almost the same parameters as plasma. However, all the same, at a certain angle, the contrast in LCD displays decreases.
  • Screen resolution. The LCD screen has the best resolution, since it is easier to reduce a pixel than a gas cell. Plasma TVs with high resolution do not yet exist.
  • Light uniformity. Each of the plasma cells is a separate light source, in connection with this, the screen is illuminated evenly. In LCD models, the uniformity of illumination depends on how good the backlight is.
  • Weight. Although both types of screens are similar in appearance, LCD is lighter than plasma counterparts, the design uses transparent plastic instead of glass.
  • Functionality. Both models have identical control functions.
  • Energy efficiency. Plasma consumes much more electricity, as it needs the constant operation of the fans to cool the device. In this case, the advantage will be on the side of liquid crystal panels, since they consume several times less energy than plasmas with a power of 350-450 W.
  • Response speed. In plasmas, electricity passes through the gas at maximum speed, which allows you to increase the response speed. In LCD models, liquid crystals do not transfer electricity as quickly, but thanks to the use of transistors, it was almost possible to achieve the same response speed as plasmas.
  • Service life. Plasma TVs work no more than 30 thousand hours. However, from overheating, the device may last less. The service life of LCD TVs is up to 100 thousand hours. When the backlight burns out, it can be replaced, but there is a possibility of “broken” pixels.
  • Security. For the environment and humans, plasma and LCD TVs are absolutely harmless.
  • Appearance. Both models are thin and flat, can be hung on the wall and connect to the Internet and local network. But do not forget that LCD models are lighter.
  • Reliability. Plasmas are less susceptible to mechanical damage.
  • Cost. Plasma TVs with a large display diagonal are not so expensive. A large LCD screen is quite difficult to manufacture, so a TV with the same diagonal as a plasma will cost significantly more.
  • Watching movies and programmes. Both models allow you to watch TV programs, movies and other content in different screen sizes and resolutions.

There are a number of features to consider when choosing a TV. They are not related to technical characteristics, but are important when choosing equipment:

  • Presence of multimedia connectors. HDMI, SCART, USB connectors greatly expand the possibilities of using technology. Using HDMI, you can broadcast a picture to a TV from a computer, smartphone or laptop. USB allows you to connect a flash drive to the equipment and read information from the media. SCART is a connector that is compatible with all known multimedia. It allows you to both transmit information and record it. When choosing, pay attention to where the connector is located. If it is displayed externally on the panel, it will be much more convenient to use the TV.
  • 3D and Smart TV support function. Plasma TVs have this feature. 3D mode allows you to see the image in three dimensions. But you can watch movies and programs in this format only after recording them first.
  • Manufacturer. Currently, different companies are engaged in the production of TVs.
