LG’s OLED phone screens are bad, but its TVs are top-notch—what gives?

Are LG’s OLED screens terrible, or are they the best in the business? Reading tech reviews, you’ll see both of those statements. That’s since you’ll get two extravagantly opposite stories about OLED depending on either you’re reading a TV or phone review.

Phone critics contend LG OLED panels have peculiarity issues. Meanwhile, TV critics contend the opposite—that LG’s OLED panels are marvelous. It’s treacherous for the consumer, so let’s explain right now. The critics aren’t contradicting any other, since LG creates industry-leading, extraordinary OLED TV panels, and, at the same time, the same company creates rarely cryptic OLED phone panels. That’s not to contend that LG’s OLED TVs are perfect—every record has tradeoffs, like very teenager tone banding in this case. But at a minimum, they’re up there with the best consumer TVs the marketplace has nonetheless seen.

So since did the Pixel 2 XL and LG V30 have bad phone displays, when LG clearly can make a good OLED screen for TVs? And since do the Galaxy S8+ and iPhone X have better OLED screens than the Pixel 2 or the LG V30, but still not as good as LG’s TVs?

What is OLED?

OLED stands for “organic light-emitting diodes,” and it’s very opposite from the renouned LCD screen record seen in many phones and TVs in new years. For a strong outline of the tech, examination the prior explainer essay about OLED. But here’s what matters to many users and viewers: distinct LCD panels used in many phone and TVs, OLED panels don’t have a backlight. Each pixel is away lit.


Because any pixel can be tranquil individually, OLED TVs can display true, tangible blacks—something LCD displays simply aren’t able of and never will be. This could have implications for battery life in the prolonged run, but, in the meantime, it really leads to better picture peculiarity interjection to increasing contrariety ratios. Response times are mostly utterly good, as well—as are observation angles, in some implementations.

OLED TVs entered the marketplace at very high cost points. This was since certain materials used to make them, like iridium, are partially expensive. And many of those materials are squandered in the prolongation process; manufacturers would furnish the homogeneous of several radio panels but would have to drop the infancy of those materials in office of just one panel. This opening has sealed over time, bringing down prices.

There have been experiments from several manufacturers with OLED phone screens in new years, but with the Pixel 2 XL, the iPhone X, the Samsung Galaxy S8, and more, this seems to be OLED’s mobile moment at prolonged last.


LG calls its phone OLED displays POLED and its TVs OLED, while Samsung calls its phone displays AMOLED. It turns out that, at slightest between POLED and AMOLED, there’s little difference; it’s mostly selling speak.

There are two forms of OLED displays—passive- and active-matrix. The “AM” in AMOLED stands for active-matrix. Passive-matrix OLED panels are cheaper and easier to make, but peculiarity moving images all but need the use of active pattern OLED panels. So for the purpose of smartphone comparisons, Samsung’s nomenclature is pointless—virtually all complicated OLED smartphones or TVs are active-matrix. You could really just contend OLED.

LG’s POLED is also irrelevant as vernacular goes. OLED displays can be done with a accumulation of opposite substrate materials. They can be plastic, or they can be glass. Glass substrates are generally better for picture quality, but plastic is cheaper, some-more durable, and some-more simply bendable into surprising shapes—think about those winding edges on Samsung’s Galaxy S8+ display. On complicated smartphones, both LG and Samsung use plastic substrates. So the P for “plastic” is also invalid for comparison. They’re all plastic, at slightest where phones are concerned.

That doesn’t meant there aren’t differences between Samsung’s panels and LG’s, though. We’d adore to privately diagnose since LG’s panels are worse than Samsung’s, but there are many probable culprits in both famous and opposite differences. That said, conjunction company shares all the sum of its prolongation routine publicly.

But Samsung’s panels—as used in the Samsung Galaxy S8+ and the iPhone X—have been better perceived than LG’s. Just demeanour at these comparisons prisoner and combined by Ars’ own Ron Amadeo in his Google Pixel 2 and Pixel 2 XL review, and his comparison between an LG OLED-equipped LG V30 and both an LCD-equipped LG G6 and a Samsung OLED-equipped Galaxy S8:

When we reviewed the iPhone X, which uses a Samsung-made OLED panel, we found it had much some-more in common with the Galaxy S8 where the screen was concerned, and DisplayMate’s research called it the best smartphone display out there. It had some conspicuous tone changeable at an angle, and burn-in may be a risk. But blotchiness, low-light performance, and tone oversight were not poignant concerns.

But in any case, nothing of these displays hold a candle to LG’s OLED TVs.

TVs and phones

LG’s OLED TVs have few of the problems autochthonous in phone displays. Yes, there’s tone banding. But an LG C7 or B7 consumer OLED TV’s picture appears scarcely the same either noticed from a tough angle or directly from the front. Burn-in is a concern, but it takes many hours of a certain image’s determined presence—like say, the always-visible UI elements in a video diversion over dozens or some-more likely hundreds of hours of play—to create an issue. In many cases, the screen earnings to normal and clears up sincerely fast after observation other content. And examination the gray unity picture in Rtings.com’s LG B7 OLED TV examination to the images from OLED smartphones above. It’s not even close.

The approaches, materials, and technologies at play in these TVs are infrequently opposite in elemental ways compared to phones. For example, many (but not all) phone OLED displays have used what’s called a “diamond pixel arrangement,” which is considerably opposite from the WRGB arrangement used in LG’s OLED TVs.

In LG’s OLED TVs, any pixel is a white OLED indicate of light done out of 3 colored layers, but tone filters actually create the red, green, and blue subpixels. It competence seem like an peculiar approach, but it has advantages in longevity, observation angles, and cost.

But even yet the OLED TVs make compromises, OLED phones make bigger ones. There is no beating around the bush: the solid pixel arrangement used in Samsung’s phones, in the iPhone X, and in many other OLED phones sacrifices correctness and quality.

So many factors are at play, though, that we can’t just censure the differences on that. Phone manufacturers have to worry about energy expenditure more. LG TV panels are done using opposite materials and prolongation processes than LG phone panels. And there are likely countless differences that are not publicly known.

Samsung has been operative for several years to mature its phone OLED row technologies. LG has been operative for years doing the same on TVs. LG’s display multiplication reportedly wanted to concentration on incomparable panels for a prolonged time, so the company is now personification catch-up on mobile. But regardless of the manufacturer, not all OLED panels are combined equal; that picture gets even clearer when comparing phones and TVs. The record may have been around for years now, but it’s still only just maturing—especially when it comes to mobile.

So don’t write off OLED TVs just since the Pixel 2 XL and LG V30 have bad OLED screens. And design OLED to keep getting better in all forms of products.
