Brief explanation of Plasma, LCD, LED, and OLED TVs

Televisions have come a long way since they first appeared in households over sixty years ago. Nowadays, we have a variety of display technologies available, making it easier than ever to find the TV that best fits our lifestyle and needs. But with all of the choice comes confusion as to which type of television is actually the best for us. In this guide, we will provide a brief explanation of plasma, LCD, LED, and OLED TVs so that you can make an informed decision when buying your next TV.

Plasma TVs are composed of many pixels that are filled with tiny bubbles of gas called plasmas. When electricity is applied to these plasmas, colored light is produced and brighter pictures with more vibrant colors. Plasma TVs often offer the widest viewing angle but due to their fragile composition; you may experience burn-ins if you leave the same picture on screen for long periods of time or watch programs with static images like news or sports scores.

LCD TVs use two sheets of polarizing material with a liquid crystal solution sandwiched between them to create an image onscreen. While they are not capable of producing as sharp images as plasma TVs, they do not require as much power and generate less heat than plasma models. They also tend to be thinner than other types making them ideal for wall mounting purposes.

LED TVs use Light Emitting Diodes (LEDs) instead of Cathode Ray Tubes (CRT) used in traditional televisions sets giving them more vibrant colors similar to Plasma displays at lower power usage and reduced space requirements compared to other types like LCDs or Plasmas which require backlights to illuminate their screens effectively. For example, recent energy efficiency standards make it almost impossible for any new CRT based televisions sets to be produced today while LED’s consume almost 50% less energy then traditional CRT televisions sets despite having much better image quality overall. Moreover, LED’s can also last longer than traditional LCDs since this technology uses cold cathode fluorescent lamps (CCFLs) as its backlight source resulting in longer lifespans compared other display technologies on the market today.

OLED stands for Organic Light Emitting Diode; these are self-emitting pixels creating perfect black levels delivering greater contrast ratio compared other technologies such as LED/LCD. This is due from OLED’s ability from lighting up individual pixels separately from each other reducing power output requirements significantly. Since each pixel contains three layers responsible for emitting light resulting from transmission from electric current, brightness settings can be precisely adjusted according owner’s preferences giving users more control over how dark or bright their display experience is going more cost efficiently compared competing products in market today.


Liquid Crystal Display (LCD) TV is a type of flat-panel display technology that uses two sheets of polarized glass to enhance picture quality. It works by passing the light from a backlight through a layer of liquid crystals, which then filters and organizes the light into pixels that display an image.

LCD TVs make up the majority of TVs on the market today—but they’re not as thin, power-efficient, or expensive as OLED televisions. Advantages of LCD include vibrant colors, wide viewing angles, good motion performance, and affordability. Disadvantages include limited brightness in dark areas and slightly lower contrast ratios compared to OLED displays; this makes them less suitable for very dark environments where deep blacks are desired.

How it works

The four types of flat-panel TVs—plasma, LCD, LED, and OLED—all work differently to project images.

Plasma TVs use tiny pixels made of gas to produce bright pictures. LCD (Liquid Crystal Display) displays rely on a layer of liquid crystals that open and close or allow light through in order to create an image. LED (Light-Emitting Diode) TVs use a series of small light-emitting diodes arranged in blocks behind the LCD display to create the image.

OLED (Organic Light-Emitting Diode) TVs combine the best elements of both technology— utilize groups of tiny organic light-emitting diodes that create their own illumination and emit three primary colors of light (red, green, blue). The different hues are used to compose vastly more vivid and lifelike images than the other TV generations can produce.


Each type of television has its own advantages, and choosing the right one for you will depend on your individual needs and preferences.

Plasma TVs typically offer excellent picture quality with brighter colors, deep blacks and smooth motion. This is because each pixel can be individually turned on or off, resulting in higher contrast ratios than LCD displays. They are also lightweight, thin and don’t require as much energy to operate as LCDs. The downside is that they can suffer from glare and there is a risk of screen burn-in if the same image remains on the screen for a long time.

LCD TVs are very common due to their low cost and excellent picture quality. They produce a bright picture with sharp colors and good contrast ratios, and they don’t suffer from glare or screen burn-in like plasma TVs do. They also require less energy than plasmas, but their viewing angles tend to be more limited than plasma displays.

LED TVs improve upon LCD displays by using LED backlighting instead of traditional fluorescent lighting for better brightness levels as well as energy savings. This type of television offers improved color accuracy along with thinner designs than traditional LCDs, but viewing angles tend to be similar to that of LCDs. Plus, LED televisions come in ultra-thin models that make them perfect for wall mounting.

Lastly, OLED televisions are the latest generation of televisions offering remarkable image quality with true colors, amazing contrast levels and wide viewing angles all while being extremely thin in size since no backlights are used like in an LED TV setup. However they have relatively high costs associated when compared with other types of TV technologies available today.


When considering whether to purchase a Plasma, LCD, LED, or OLED television, it is important to consider the disadvantages associated with each type of television.

Plasma TVs: Plasma televisions suffer from short lifespan and poor black levels due to the older technology. The technology also uses a considerable amount of energy and can be prone to image burn-in if not properly cared for.

LCD TVs: LCDs have issues with blurriness in fast-moving images as well as contrast and color shift in certain angles. Additionally, they can suffer from screen flicker when viewed from different positions due to their use of backlight. Lastly, like plasmas, their short lifespan could mean you’ll have to buy a new TV again soon after buying it.

LED TVs: LED TVs require rest periods between on/off cycles and frequent image adjustments may cause more eye strain compared with other TV types due to the need for intense backlighting. These types of TVs are also known for having lower black levels compared to plasmas and OLEDs.

OLED TVs: OLED televisions are subject to several drawbacks including hassle dealing with delicate materials when repairing them as well as potential burn-in since they don’t use light diffusion technologies like many other TV types do. An additional negative is more reflections than non-OLED LEDs resulting in possible loss of contrast under bright lights.


Light Emitting Diode (LED) TVs are a type of LCD digital television that utilizes light-emitting diodes for backlighting instead of the traditional fluorescent or CCFL (Cold cathode fluorescent lamp)lamps used in regular LCD televisions.

The LED backlighting of the LED TV allows it to be extremely thin, lightweight and energy efficient. Additionally, LED TVs can brighten each individual pixel separately, providing a wider range of contrast and more vibrant colors than their conventional LCD counterparts.

LED TVs are also capable of deeper blacks and faster response times providing greater motion clarity as compared to standard LCD models.

How it works

The way in which a television produces an image is an important factor to consider when making a purchase. Plasma, LCD, LED and OLED are four of the most common technologies used in today’s TVs. Each type of display emits light in a different way and provides a unique viewing experience.

Plasma TV: In a plasma display, each pixel is made up of hundreds or thousands of small cells containing electrically charged gases. When the electricity is activated, it excites the tiny particles located within each cell, causing them to glow with intense color and produce light.

LCD TV: Liquid crystal display (LCD) technology uses liquid crystals that are sandwiched between two glass plates. The crystals are activated by either polarized light passing through them or electrical current which causes them to change their orientation creating an image on the screen.

LED TV: Light emitting diode (LED) televisions use both liquid crystals and light-emitting diodes (LEDs). LEDs are tiny semi-conductors that emit light when electricity passes through them. LEDs significantly reduce power consumption while creating brighter images This technology also allows for thinner displays that are much lighter than plasma or LCD TVs.

OLED TV: Organic light-emitting diode (OLED) technology is similar to LED but it uses organic materials that naturally emit light without requiring any additional backlighting. OLEDs offer incredibly bright displays with sharp contrast and vibrant colors with almost zero energy consumption making them the ideal choice for energy conservation initiatives.


LED (light-emitting diode) and OLED (organic light-emitting diode) displays are the most current technology available. In general, OLEDs offer greater contrast, deeper blacks and brighter colors than LCDs, though LCDs typically cost less.

Plasma TVs have several advantages over both LED and OLED displays. Plasma TVs offer superior black levels with better shadow detail that can’t be matched by LED or OLEDs. They are also much less likely to suffer from motion blur found in older LCD displays. Plasma TVs also tend to use less electricity than LCD or LED models, increasing their energy efficiency and helping to reduce their overall operating costs.

LED TVs have several advantages over both LED and OLED screens as well. LEDs are much thinner than traditional plasma televisions, making them more space-efficient in smaller spaces or even wall mounting them if desired. Also, advancements in backlighting technology have allowed manufacturers to create a much larger range of brightness levels which can give the appearance of a higher static contrast ratio than plasmas do, resulting in better shadow detail reproduction and increased depth to the image on screen. Additionally, LEDs often prefer cooler running temperatures which not only increase the lifetime of the television but also helps create a cooler environment for your living room as well.


Despite the wide range of advantages offered by plasma, LCD, LED, and OLED television technologies, each also comes with certain drawbacks or disadvantages.

Plasma TVs tend to suffer from screen burn-in and image retention if the same images or logos remain unchanged on the screen for long periods. This issue has been minimized on newer models through automatic compensation techniques that detect image retention and quickly refresh the affected part of the display. Additionally, these type of TVs can have poor performance at higher altitudes due to air pressure issues which may cause them to overheat.

LCD TVs are more power efficient than Plasmas but experience slow response times which can result in blurry images when displaying fast-moving objects. They also have difficulty producing a bright enough picture for use in well-lit rooms. In addition, these types of TVs often cannot match edge-lit LED sets since their backlighting isn’t uniform resulting in uneven brightness levels in some scenes.

LED TVs commonly feature blooming when used at high brightness settings; this occurs when light leaks around objects such as black bars or menus and produces a halo effect around them. Additionally, because they rely mostly on white LEDs instead of color-producing organic diodes (RGB), they may suffer from color accuracy issues—especially if cheap panels are used during construction process that don’t have enough reds and greens present to accurately reproduce life-like pictures.

Finally, OLED sets are still an emerging technology with not many products available on the market—resulting in higher prices than those seen for LEDs or LCDs—while few OLEDs currently available offer poor viewing angles due to contrast ratio deterioration at off angles as well as high input lag making them less suitable for playing video games than other tv technologies.


Organic Light Emitting Diode (OLED) televisions use self illuminating diodes to produce the light necessary to create picture. This is a relatively new technology that produces exceptional picture quality by enabling deeper blacks, a higher contrast ratio and better viewing angles than other display technologies.

OLED TVs provide nearly limitless viewing angles, as opposed to LCD and LED because they don’t rely on backlighting or color filters. This allows millions of individual pixels to be turned off for deeper black levels in dark-room environments, it also enables faster response times for better motion performance when used for gaming.

Additionally, OLEDs make slimmer designs possible due to their thinner architecture which reduces the overall thickness of the TV and makes mounting easier with less space taken up behind the TV itself. Furthermore, these sets are much more energy efficient than their LCD counterparts because they require far less power in order to operate than other types of displays.

As OLED technology progresses, we can only expect these advantages over older tech like plasma and LCD will become even more evident with every passing year.


Each television technology has its own advantages and drawbacks.

Plasma TVs are capable of delivering deep blacks, wide viewing angles, and good motion resolution. LCD and LED TVs usually have the brightest images, due to their improved backlighting technology, but have narrow viewing angles that can cause color shifting when viewing from off-angles. OLED TVs provide some of the best image quality available due to their ability to produce true blacks, wide viewing angles, tight pixel spacing for an extra sharp image, and extremely fast response times for enhanced motion resolution.

While all these technologies provide picture quality benefits that are great for watching television shows or movies, there may be specific advantages for different televisions that determine which one is right for you. Therefore, it is important to consider factors such as your budget and usage habits before making a purchase decision.


No matter the type of flat-screen television you choose, there are certain drawbacks to consider.

Plasma televisions are heavy and bulky, making them difficult to move and install. LCDs tend to be expensive, with more expensive models featuring higher resolutions and wider viewing angles. LED TVs require a great deal of power, so they may be more costly for households in terms of electricity over time. OLED TVs are quite fragile and expensive; since organic light-emitting diodes are used in these TVs, any pressure or minor damage can lead to permanent problems with the display quality.

Overall, all types of flat-screen televisions require a degree of care to ensure they maintain their quality over time, though some require less maintenance than others.

VII. Conclusion

The type of television you decide to buy depends on a variety of factors. LCD, LED, OLED, and Plasma TVs all vary in price, size, performance and features. Factors such as the size, available space for the television and how much you would like to spend all need to be considered when purchasing a TV.

Generally speaking, LED televisions are the most popular type on the market due to their relatively low price point and good quality. OLED televisions offer superior picture quality but at a higher price point. Plasma televisions have been discontinued but they can still be found at clearance prices and offer excellent contrast ratios and deep black levels.

Ultimately, it is important to do your research before purchasing a television in order to make sure that you get the best possible deal.

Summary of the main differences between Plasma, LCD, LED, and OLED TVs

Today, there are several different types of TVs available, from LCDs and LEDs to the latest OLED models. Although these technologies may appear similar on the surface, there are distinct differences between each type to be aware of before making a purchase.

Plasma TVs were once a very popular option for television viewers. These use gas rather than liquid crystal to display an image and tend to have a richer color palette. However, they have limited viewing angles and can sometimes suffer from “burn-in” if left on the same image too long.

LCD TVs are constructed differently than plasma TVs in that they do not use gas, but instead rely on liquid crystals and backlighting technology. They offer a viewing angle expansion relative to plasma displays but buy may lack clarity if viewed off-angle or they can suffer from edge dimming in dark environments – a phenomenon caused by its inability to illuminate sections of its backlight uniformly.

LED (Light Emitting Diode) TVs take LCD technology one step further with improved picture quality thanks to their adjustable backlighting capabilities that enable more precise brightness adjustments during darker scenes even when viewed at an angle along with higher peak brightness values for brighter scenes involving outdoor settings such as sports events or beach scenes etc. These improvements result in improved picture contrast, which means better detail in shadows of images as well as enhancing colors produced by the display within full high definition range limits [1920 x 1080].

Finally, OLED (Organic Light Emitting Diode) TV’s represent the latest generation of TV solutions offering true blacks (no light bleed through when displaying black elements) due to their ability for individual pixel control which allows for independent dimming capabilities across very small areas for increased accuracy with subtle shades performances that result in better color accuracy and reduced motion blur during fast action sequences found sports or gaming events etc.. Additionally managing power consumption is achieved with greater efficiency as well thanks to their variable backlight control capabilities along dynamic dimming feature effects resulting from driver circuits distribution designed into their active matrix layer layout design architecture.
