The world of TVs is all about acronyms. You see them all over the place you store for units from the likes of Samsung, LG, TCL, Sony, and others, and these are essential three-, four-, and five-letter codewords to decipher. For probably the most half, we’re all conversant in acronyms like HD and 4K, however once we begin throwing round letter pairings like OLED, LED, QLED, and now QD-OLED, issues can get complicated in a short time. Not to fret although, we’re right here to assist.
The examples above are all simply completely different lighting and display applied sciences that TV firms use to get an image in your TV display. Today, we’ll give attention to evaluating two of the most well-liked display applied sciences: OLED and LED. The former stands for “natural light-emitting diode,” and the latter stands for “light-emitting diode”. While these two TV varieties might look related on the shelf, they couldn’t be extra completely different in the case of how every set produces an image, and the way colourful or vivid that image could be.
If you’re available in the market for a brand new TV, we’ve additionally rounded up the very best 4K TV offers and the very best OLED TV gross sales obtainable.
What does LED imply?
Samsung / Samsung
Non-OLED TVs are made of two fundamental elements: an LCD panel and a backlight. The LCD panel comprises the pixels, the little coloured dots that make up a TV’s picture. On their very own, pixels can’t be seen; they require a backlight. When gentle from the backlight shines via an LCD pixel, you possibly can see its shade.
The “LED” in LED TV merely refers to how the backlight is made. In the previous, a thicker and fewer environment friendly expertise referred to as CCFL (cold-cathode fluorescent gentle) was used. But nowadays, nearly each flat-screen TV (sans OLED) makes use of LEDs as its supply of backlighting. Thus, once you see the time period “LED TV,” it merely refers to an LED-backlit LCD TV.
That mentioned, not all LED TVs are created equal. There could be variations within the quantity and high quality of the LEDs used, which ends up in variations in issues like brightness and black ranges. For occasion, you’ve most likely heard of QLED TVs. This is a sort of LED TV that makes use of quantum dots to realize higher brightness and shade. We’ll talk about QLED extra beneath, however right here’s an awesome overview of the variations between QLED and OLED TVs.
What does OLED imply?
LG
As talked about, the “OLED” in OLED TV stands for “natural light-emitting diode.” OLEDs have the weird property of having the ability to produce each gentle and shade from a single diode once they’re fed electrical energy. Because of this, OLED TVs don’t want a separate backlight. Each pixel you see is a self-contained supply of shade and light-weight.
Some of the inherent advantages of OLED screens are that they are often extraordinarily skinny and versatile. But the largest profit once we evaluate them to LED TVs is that every particular person pixel receives its personal luminance and energy (versus LED TVs, which have persistent pixels that require an exterior supply of gentle to see). When it’s on, you possibly can see it. When it’s off, it emits no gentle in any respect — it’s fully black. We’ll talk about how this impacts black ranges in a second.
Currently, LG Display, famed for top-line LG OLEDs just like the G3 Series, is the one producer of OLED panels for TVs. And due to partnerships between LG Display and types like Samsung and Sony, you’ll have the ability to purchase Samsung and Sony OLEDs, such because the Samsung S95C and Sony A95L. While these fashions nonetheless use picture-processing instruments developed by every respective firm, the OLED panels are from LG Display.
Is QLED the identical as OLED?
Zeke Jones / Digital Trends
While these pesky acronyms might sound related, an OLED TV is not the identical as a QLED TV. In truth, these two varieties of TVs couldn’t be extra completely different. Remember how OLED TVs are succesful of producing gentle and shade with out precise backlighting? Well, it’s precisely the other for QLED units.
QLEDs are literally most much like conventional LED-LCD TVs. The solely distinction is that QLEDS embody a layer of quantum dots between the backlight and the display. When gentle passes via these chemical blots, the sunshine supply is enhanced earlier than hitting the again of the TV display. And by enhanced, we imply a brighter and much more colourful image than you’d get on a non-QLED LCD display.
But what about QD-OLEDs?
Nowadays, there’s really an image expertise that mixes the very best of QLED lighting and quantum dots with natural, self-emissive pixels. These TVs are referred to as QD-OLEDs, and so they’re presently made by each Samsung and Sony. Without diving into the true nitty-gritty of the image tech, we are able to suppose of a QD-OLED as a conventional OLED infused with quantum dots. The finish consequence of these varieties of shows is a TV that may obtain deep colours and distinction, in addition to superior brightness.
Which is higher, OLED TV or LED TV?
LG Electronics
Now it’s time to pit these two applied sciences in opposition to one another and see how they stack up in the case of standards like colours, distinction, viewing angle, brightness, and different efficiency concerns.
Editor’s notice: Since OLED TVs are nonetheless a premium display, we now have in contrast OLED solely to equally premium LED TVs armed with related efficiency potential (besides, of course, within the worth part).
Black degree
A display’s capability to provide deep, inky blacks is arguably an important think about reaching wonderful image high quality. Deeper blacks permit for greater distinction and richer colours (amongst different issues) and thus a extra reasonable and dazzling picture. When it involves black ranges, OLED reigns because the undisputed champion.
LED TVs depend on LED backlights shining behind an LCD panel. Even with superior dimming expertise, which selectively dims LEDs that don’t have to be on at full blast, LED TVs have traditionally struggled to provide stable black ranges and might undergo from an impact referred to as “gentle bleed,” the place lighter sections of the display create a haze or bloom in adjoining darker areas.
OLED TVs undergo from none of the black-level issues of conventional LED TVs. If an OLED pixel isn’t getting electrical energy, it doesn’t produce any gentle and is, due to this fact, completely black. Sounds like an apparent option to us.
Winner: OLED TV
Brightness
When it involves brightness, LED TVs have a substantial benefit. Their backlights could be produced from giant and highly effective LEDs. With the addition of quantum dots, that brightness could be preserved whilst the scale of the person LEDs will get smaller. OLED TVs can get fairly vivid, too, and with such darkish black ranges, the distinction between the brightest and darkest spots on the display is all of the extra exaggerated. But cranking OLED pixels to their most brightness for prolonged intervals reduces their lifespan, and the pixel takes barely longer to return to whole black.
With these concerns in thoughts, it’s necessary to notice that each one fashionable TVs — whether or not OLED, LED, or QLED — produce greater than satisfactory brightness. The consideration then turns into the place the TV shall be used. In a darkish room, an OLED TV is going to carry out finest, whereas LED TVs will outshine them (fairly actually) in additional brightly lit environments.
It also needs to be famous that there have been massive beneficial properties just lately in OLED brightness, making them completely appropriate for almost any state of affairs, save for direct daylight beaming onto the display. Still, when put next straight, LED TVs have the sting.
Winner by a nostril: LED TV
Color house
OLED used to rule this class, however by bettering the purity of the backlight, quantum dots have allowed LED TVs to surge ahead in shade accuracy, shade brightness, and shade quantity, placing them on par with OLED TVs.
Those searching for TVs with Wide Color Gamut or HDR will discover each OLED and LED TV fashions that assist these options. OLED’s higher distinction ratio is going to offer it a slight edge in phrases of HDR when considered in darkish rooms, however HDR on a premium LED TV display has an edge as a result of it could actually produce well-saturated colours at excessive brightness ranges that OLED can’t fairly match.

Response time, refresh charge, and enter lag
EA Sports
Response time refers back to the time it takes for every particular person pixel to alter states. A pixel’s state is not solely its shade but in addition its brightness. With a quicker response time, you get much less movement blur and fewer artifacts (supply materials however).
Because OLED pixels mix the sunshine supply and the colour in a single diode, they’ll change states extremely quick. By distinction, LED TVs use LEDs to provide brightness and tiny LCD “shutters” to create shade. While the LED’s brightness could be modified right away, LCD shutters are by their nature slower to answer state modifications.
OLED presently gives the quickest response time of any TV expertise in use in the present day, making it a transparent winner on this regard.
Refresh charge is how typically the whole picture on-screen modifications. The quicker the speed, the smoother issues look, and the better it is to pick particulars in fast-moving content material like sports activities. Most new TVs are succesful of refresh charges of 120Hz, which suggests the whole picture is up to date 120 instances each second. Some go as excessive as 144Hz when paired with a suitable gaming PC.
If refresh charge had been merely a matter of hertz, we’d name OLED TV the winner, just because it could actually obtain charges of as much as 1,000 instances greater than LED TVs. But absolute velocity isn’t the one consideration. Unlike motion pictures and TV exhibits, which use a single refresh charge, video video games typically make use of one thing referred to as variable refresh charges, which merely implies that the speed modifications throughout completely different elements of a sport. If a TV can’t match these charge modifications, you find yourself with picture tearing — a visual jerkiness that comes from the disparity between the speed the sport is utilizing and the speed the TV needs to make use of.
That’s why avid gamers, specifically, need TVs that may deal with VRR or Variable Refresh Rate. But neither OLED nor LED TVs have an actual benefit in the case of VRR. Some fashions have the function, and a few don’t. That being mentioned, most TVs nowadays are integrating VRR, with even some entry-level fashions introducing the function. Your gaming system additionally has to assist VRR, although that shouldn’t be a lot of a difficulty in case you personal a brand new Xbox Series X, PS5, or perhaps a PS4/Xbox One.
Finally, enter lag is the hole in time between once you press a button on a sport controller and the corresponding motion exhibits up on-screen. Input lag could be a drawback when TVs introduce rather a lot of image processing that causes a slow-down within the sign they obtain. But most fashionable TVs have a sport mode, which eliminates the processing and reduces enter lag to barely discernible ranges. In the long run, all TVs will have the ability to sense the presence of a online game and swap to this mode robotically, returning to the processed mode when gaming stops.
OLED takes this one on its energy in response instances.
Winner: OLED TV
Viewing angles
OLED, once more, is the winner right here. With LED TVs, the very best viewing angle is lifeless heart, and the image high quality diminishes in each shade and distinction the additional you progress to both aspect. While the severity differs between fashions, it’s all the time noticeable.
As far as OLEDs go, you should not have any challenge with viewing angles till you begin entering into off-angle extremes. Those of us sitting on the farthest ends of the sofa might begin to expertise some brightness and shade degradation, and that often doesn’t begin taking place till you’re round 85 p.c off-center.
That being mentioned, many Samsung QLED TVs and LEDs from different noteworthy names have been using anti-reflective coatings, which assist to chop down on ambient gentle affecting the display. Anti-reflective seals additionally assist to make off-angle viewing a lot much less of a difficulty. So whereas OLED nonetheless beats these fashions out ultimately, the hole is closing rapidly.
Winner: OLED TV
Size
LG
At one time, big-screen OLED TVs had been astronomically priced. But except you’re taking a look at a flagship mannequin, that’s not likely the case anymore. OLEDs can vary in dimension from 40 inches for some of the smallest fashions, to 85 inches-plus on some of the most important choices. LEDs play in the identical ballpark although. In truth, some of the very best costs on 75-inch-plus TVs are from manufacturers like Samsung, Sony, TCL, and Hisense, all of which supply entry-level, mid-tier, and premium LED and QLED TVs. Yes, Samsung and Sony produce QD-OLEDs too, however these fashions are sometimes size-capped at round 77 inches.
Taking all this into consideration, we’re going to offer one other level to Team LED. While present OLEDs could also be competitively sized and priced accordingly, LED has provided greater sizes at higher costs for an extended interval of time.
Winner: LED TV
Lifespan
One factor you’ve most likely heard one million instances over about LED expertise in all its kinds is that it’s extraordinarily vitality environment friendly. And of course, this laurel interprets to the world of TVs. Barring points like software program glitches, energy surges, and lifeless pixels, LED TVs ought to final for greater than six years. You might even get near 10 years out of your LED in case you preserve the backlight turned down and the viewing hours to a minimal.
OLED TVs aren’t a lot completely different although. Other than display burn-in (which we’ll cowl extra beneath), your OLED doesn’t depend on an LED backlight for pixel energy. Generally talking, most OLED TVs ought to final for as much as 100,000 hours, which usually interprets to eight to 10 years of utilization.
Winner: Draw
Health
Can one kind of TV be more healthy for you than one other? If you consider that we have to be cautious about our publicity to blue gentle, particularly towards the night, then the reply might be sure. Both OLED and LED TVs produce blue gentle, however OLED TVs produce significantly much less of it. LG claims its OLED panels solely generate 34 p.c blue gentle versus LED TV’s 64 p.c. That stat has been independently verified, and LG’s OLED panels have been given an Eye Comfort Display certification by TUV Rheinland, a requirements group primarily based out of Germany.
Will it make a distinction to your total well being? We suppose the jury is nonetheless out, but when blue gentle is a priority, you need to take a severe take a look at OLED TVs.

Screen burn-in
An instance of display burn-in on an OLED TV. Note that the seen zebra sample, often known as moire, is attributable to taking a photograph of a TV display and is not half of the burn-in. Ian O’Shaughnessy / Digital Trends
We embody this part begrudgingly, each as a result of burn-in is a misnomer and, for most people, the impact is not going to be a difficulty.
The impact we’ve come to know as burn-in stems from the times of the boxy CRT TV when the extended display of a static picture would trigger a picture to seem to “burn” into the display. What was really taking place was the phosphors that coated the again of the TV display would glow for prolonged intervals of time with none relaxation, inflicting them to wear down and create the looks of a burned-in picture. We suppose this ought to be referred to as “burn out,” however we’ll set that one apart.
The similar challenge is at play with plasma and OLED TVs as a result of the compounds that gentle up can degrade over time. If you burn a pixel lengthy and laborious sufficient, it’s going to dim prematurely forward of the remainder of the pixels, making a darkish impression. In actuality, this is not very more likely to trigger an issue for most individuals — you’d should abuse the TV deliberately to get it to occur. Even the “bug” (logographic) that sure channels use disappears typically sufficient or is made clear to keep away from inflicting burn-in points. You’d have to look at ESPN all day, every single day for a protracted, very long time on the brightest attainable setting to trigger an issue, and even then, it nonetheless isn’t very probably.
That mentioned, the potential is there, and it ought to be famous. (This is additionally a contributing issue within the dearth of OLED laptop displays in the marketplace, as laptop screens are much more more likely to display a static picture for hours on finish.) Since LED TVs aren’t prone to burn-in, they win this combat by a technicality.
Winner: LED TV
Power consumption
OLED panels require no backlight, and every particular person pixel is extraordinarily energy-efficient. LED TVs want a backlight to provide brightness. Since LEDs are much less energy-efficient than OLEDs, and their gentle should go via the LCD shutters earlier than it reaches your eyes, these panels should devour extra energy for a similar degree of brightness.
Winner: OLED TV
Price
When it involves total worth, OLED TVs are historically costlier than LED fashions. However, we now have seen costs beginning to drop all the way down to extra manageable {dollars} and cents, particularly if there are any reductions working. Conversely, LED TVs can vary in worth from a number of hundred {dollars}, even for a top quality big-screen mannequin, to a number of thousand {dollars}, making them total extra accessible than OLEDs. While costs of the highest-quality LED TVs hover at almost the identical vary as the worth of OLEDs, when judged by worth and worth alone, LED TVs can nonetheless be acquired for a pittance compared.
Winner: LED TV
We have a winner!
LG
In phrases of image high quality, OLED TVs nonetheless beat LED TVs, despite the fact that the latter expertise has seen many enhancements of late. OLED is additionally lighter and thinner, makes use of much less vitality, gives the very best viewing angle by far, and, although nonetheless a little bit costlier, has come down in worth significantly.
OLED is the superior TV expertise in the present day. If this text had been about worth alone, LED TV would nonetheless win, however OLED has come a good distance in a short while and deserves the crown for its achievements. Regardless of which expertise you in the end resolve on, that’s not the one issue that it’s good to think about, so make sure you test our TV shopping for information to be sure you’re shopping for the precise TV to fulfill your wants.
