Samsung QLED vs. LG OLED: How the two best TV technologies compare in 2019

When it involves TV technology, the insufficient line that turns Associate in Nursing "O" into a "Q" may be a extremely massive deal.

Two rival TV brands use terribly similar acronyms to explain their best TVs. however QLED and OLED are as completely different as leopards and lions.

Samsung QLED vs. LG OLED: How the two best TV technologies compare in 2019


For a previous couple of years Samsung, the foremost widespread TV-maker within the world, has been stigmatization its best TVs "QLED." Its 2019 QLED lineup is larger than ever, with seven series encompassing twenty eight completely different models. From insane 98-inch 8K behemoths to TVs designed to appear like paintings and fashionable art, QLEDs represent the top of what Samsung's formidable engineers will wake TV patrons.

But it is not the top of image quality. That honor goes to OLED TVs.

Based on a previous couple of years of CNET's side-by-side comparison reviews, LG's OLED TVs have all delivered higher overall image quality than Samsung QLED TVs. the most recent example cellular Samsung's 2018 Q9 QLED against LG's 2019 C9 OLED and also the LG OLED won handily, delivering the most effective image quality I've ever tested. in truth, the LG B8 from 2018 conjointly beat Samsung. The Q9 continues to be a superb entertainer, however, and delivers the most effective non-OLED image I've ever tested -- however not attributable to QLED technology.

In June 2019 I reviewed the midrange Q70, which is a superb entertainer however no OLED. i have never tested any of the highest-end 2019 QLED models howeverlike the Q80 and Q90, however if I used to be a dissipated man I might still decide the most effective OLED to beat the most effective QLED TV yet again this year, albeit Samsung appears to own created a lot of enhancements than LG. Here's why.

A QLED TV is simply Associate in Nursing digital display TV with quantum dots
Let's begin with a fast outline of the 2 technologies.

OLED stands for "organic lightweight emitting diode."
QLED (according to Samsung) stands for "quantum dot crystal rectifier TV."
OLED may be a essentially completely different technology from the digital displaythe foremost style of TV nowadays.

QLED may be a variation of crystal rectifier digital display, adding a quantum dot film to the digital display" sandwich."

OLED is "emissive," which means the pixels emit their own lightweight.
QLED, like LCD, is, in its current type, a "transmissive" Associate in Nursingdepends on a crystal rectifier backlight.

The main takeaway is that QLED is nearer to regular previous digital display than it's to OLED, that I (and most alternative experts) think about a clearly completely different category of tvvery like plasma was before it.

Quantum dots are microscopic molecules that, once hit by lightweight, emit their own, otherwise colored lightweight. In QLED TVs, the dots are contained in an exceeding film, and also the lightweight that hits them is provided by Associate in Nursing crystal rectifier backlight. That lightweight then travels tho' a number of alternative layers within the TV, as well as a liquid (LCD) layer, to make the imagethe sunshine from the crystal rectifier supply is transmitted through the layers to the screen's surface, that is why we are saying it's "transmissive."

Samsung has been mistreatment quantum dots to reinforce its digital disp

lay TVs since 2015 and debuted the QLED TV stigmatization in 2017. Samsung says those quantum dots have evolved over time -- that color and light-weight output have improved, as an example. In my expertise butenhancements caused by higher quantum dots ar abundant less evident than those caused by alternative image quality factors (see below).

Other TV manufacturers conjointly use quantum dots in digital display TVs, as well as TCL and Vizio, however, do not decision them QLED TVs.

An OLED TV isn't Associate in Nursing digital display TV in the least

LCD is the dominant technology in flat-panel TVs and has been for a protracted time. It's cheaper than OLED, particularly in larger sizes, and diverse panel manufacturers worldwide, as well as LG itself, will manufacture it.

OLED is completely different as a result of it does not use Associate in Nursing crystal rectifier backlight to provides lightweight. Instead, lightweight is created by lots of individual OLED subpixels.

The pixels themselves -- small dots that compose the image -- emit lightweightthat is why it's referred to as Associate in Nursing "emissive" show technology. That distinction results in all types of image quality effects, a number of that favor digital display(and QLED), however most of that profit OLED.

Aside from LG, Sony conjointly sells OLED TVs within the North American nationwhereas Panasonic and Philips sell them in Europe. All use panels factory-made by LG show, however.

Based on my reviews, here are some general comparisons I've created between the 2.

QLED TV image quality varies over OLED. Samsung contains a bunch of QLED series, and also the costliest performs a great deal higher than the cheaper ones. that is primarily as a result of the largest enhancements within the image quality of Samsung's sets do not have abundant to try and do with quantum dots. In 2019 TVs just like the Q70, Q80, and Q90, are the results of higher full-array native dimming, bright highlights, and higher viewing angles, that facilitate them considerably outstrip QLED TVs that lack those extras, just like the Q60 in 2019.

Meanwhile, each OLED TV I've reviewed has terribly similar image quality -- all have earned a 10/10 in image quality in my tests. there's some variation among completely different OLED TVs, however, they are not nearly as vital because of the variations between numerous QLED TV series.

OLED has a higher distinction and black level. One in every of the foremost necessary image quality factors is the black level. And their emissive nature means that OLED TVs will flip unused pixels off fully, for virtually infinite distinction.

QLED/LCD TVs, even the most effective ones with the foremost effective full-array native dimming, Let some lightweight through. Resulting in a lot of washed-out, grayer black levels and blooming around bright sections.

QLED is brighter. The brightest QLED and digital display TVs will get brighter than any OLED model. Which may be an explicit advantage in bright rooms and with HDR content.

In my tests, however, OLED TVs will still get masses right for many rooms. And their superior distinction still permits them to deliver a more robust overall HDR image than any QLED/LCD TV I've tested.

OLED has higher uniformity and viewing angles. With LCD-based displays, completely different areas of the screen will seem brighter than others all the time.

And backlight structure can even be seen in some content. Even the most effective LCDs conjointly fade, lose distinction and become discolored. Once seen from seats apart from the sweet spot directly ahead of the screen. OLED TVs. Have virtually absolutely uniform screens and maintain fidelity from nearly the foremost extreme angles.

Resolution, color, video process, and alternative image quality factors ar essentially similar. Most QLED and OLED have a similar resolution, 4K. And each is able to do 8K resolution too.
Neither technology has a major inherent advantage in color or video process areas. scrutinize OLED vs. digital display for a lot of details.

QLED will get larger and smaller (and cheaper)

There are solely four sizes of OLED TV on the market today: 55-, 65-, 77- and 88-inch. Since the latter 2 value$6,500 and (cough) $30,000 severallythere is extremely solely 2 sizes most TV shoppers will afford.

Meanwhile, Samsung's QLED TVs are available 43-, 49-, 55-, 65-, 75-, 82-, 85- and, yes, 98-inch sizes. in fact-QLED digital display, TVs will get even smaller.

One massive advantage, therefore to talk, that QLED and digital display have over OLED. Is that the value of thought sizes over sixty-five inches. Giant televisions ar the fastest-growing phase of the market and show no signs of deceleration down.

As I discussed on top of, LG's 77-inch OLED prices $6,500. In the meantime, Samsung's 75-inch Q70 QLED prices $2,200. And Vizio's 75-inch P-Series Quantum is even less. Sure, neither one will beat Associate in Nursing OLED.

However, they are still wonderful performers for a common fraction of the value.

In 55- and 65-inch sizes, the highest-end, best-performing QLED models. Just like the Q90 and also the 8K resolution Q900A value over the most affordable OLED TV. There are various alternative, less-expensive QLED series in addition. However, albeit with worse image quality.

What concerning OLED burn-in?

Burn-in happens once a persistent a part of the image onscreen -- navigation buttons on a phone, or a channel emblem, news ticker or a board on a TV, as an example -- remains as a spectral background in spite of what else seems onscreen. All OLED screens will burn-in, and from everything we all knowthey are a lot of inclined than digital display displays, as well as QLED.
