For years, as the biggest maker of OLED TVs, LG has had an ideal story to inform about OLED’s many benefits. Issues like black ranges, distinction, and general image high quality.
On the flip aspect, rival Samsung has battled in opposition to it for simply as a few years, spending thousands and thousands of {dollars} highlighting one of many perceived drawbacks of OLED TV expertise: everlasting picture retention (in any other case generally known as burn-in). So it’s not stunning, now that Samsung has lastly embraced OLED tech, that LG would possibly wish to return the favor.
And that’s precisely what occurred on February 28. Throughout an invite-only on-line media occasion organized by LG and attended by Digital Developments’ in-house TV professional, Caleb Dension, the corporate was centered on a single message: Samsung’s OLED TVs have a burn-in downside.
To be clear, LG Show (the LG division that truly manufactures OLED panels) was the one delivering the message. Nevertheless it wasn’t basing the accusation by itself analysis. As a substitute, it used a set of long-term check outcomes from rtings.com, a evaluate website recognized for its in-depth, measurements-based product evaluations.
The check in query was carried out on Samsung’s first QD-OLED TV, the 65-inch 2022 S95B, a TV that makes use of quantum dots mixed with blue OLED pixels to attain its full-spectrum RGB colour. Rtings.com discovered that if left the identical picture displayed on the S95B for days at a time, with brightness set to most, everlasting picture retention occurred. The identical check additionally apparently was carried out on Sony’s 2022 A95K — the one different mannequin that makes use of Samsung’s first-gen QD-OLED panel — with related, but barely less-pronounced outcomes.
LG Show was additionally fast to level out that LG’s 2022 G2 and C2 evo OLED fashions, which had been additionally subjected to the identical punishment, appeared to return away unscathed, or at the very least with no perceptible injury within the images that had been proven to attendees.
LG Show defined that the explanation its panels fared higher is because of its use of white subpixels. The deeper that means of this clarification was misplaced on nobody. Samsung has made LG’s white subpixel a chief goal in its promotion of QD-OLED panels, claiming that the white subpixel reduces colour accuracy by washing out the adjoining subpixels.
For its half, LG is now hanging again by saying that with out the brightness increase afforded by these white subpixels, Samsung is pushing its personal OLED pixels too laborious and that burn-in is the consequence of doing so.
Is LG Show proper? Sure. Nevertheless it may not matter.
The issue with picture retention exams like those carried out by Rtings.com is that they essentially signify a worst-case state of affairs. Leaving the identical information channel on an OLED TV for days at a time with its brightness maxed out seems like an edge case at greatest. In that means, they’re somewhat paying homage to cellphone bend exams. Don’t go away the identical picture on a TV for days at a time. Additionally don’t sit in your cellphone.
To not say that nobody makes use of TVs this manner (gyms, airports, and a few bars are all locations which may do exactly that) — but when that’s your intent, try to be staying away from any OLED TV. Possibly not simply Samsung’s.
The reality — whether or not LG desires to confess it or not — is that every one OLED TVs can undergo the identical destiny because the S95B and A95K in case you push them lengthy sufficient and laborious sufficient. Burn-in occurs when some OLED pixels age at a quicker price than their neighboring pixels, which might occur when a emblem or different graphic stays on-screen for a very long time whereas the remainder of the display screen continues to point out an ever-changing set of colours and brightness. LG’s use of a white subpixel doesn’t change that truth.
What’s extra possible, in our opinion, is that LG (which has way more expertise producing and controlling OLED shows than Samsung) has merely developed its OLED TV software program and {hardware} to mitigate the worst results of burn-in when below excessive use. It hasn’t all the time been this manner. We’ve obtained instance photographs from readers who’ve older LG OLED TVs which have skilled burn-in.
Our takeaway from LG’s “I informed you so” is that homeowners of Samsung and Sony’s first-gen QD-OLED TVs ought to train the identical warning we now have all the time really useful when utilizing OLED TVs: keep away from extended, excessive brightness show of any constant picture parts. Our different takeaway: simply as LG has improved its capability to struggle OLED burn-in over time, so too will Samsung, and we now have each expectation that its next-gen QD-OLED panels can be much less inclined to burn-in than those it was making a yr in the past.
