); and it is as much as customers to examine whether or not the dual-layer OLED miracle resides as much as its guarantees.

Moreover, this expertise is claimed to offer brighter visuals and improved energy effectivity.

Single-layer OLED (Natural Gentle-Emitting Diode) screens are constructed with a single layer of natural compounds that emit gentle when {an electrical} present is utilized. This expertise permits for a variety of colours and deep blacks as a result of every pixel will be managed independently, turning on and off as wanted, eliminating the necessity for a backlight.

That is the way you get superb excessive distinction ratios and true blacks, as unlit pixels don’t emit any gentle. Single-layer OLED shows are identified for his or her thinness, flexibility, and effectivity; no surprise they’re so widespread. They provide wonderful viewing angles and response occasions, contributing to smoother animations and fewer movement blur in dynamic photographs.

In fact, single-layer OLED shows have their limitations and disadvantages. They’re prone to degradation over time, resulting in points like burn-in, the place static photographs “burn” into the show, leaving a ghostly residue. Creepy stuff!

Moreover, whereas they excel in distinction and colour accuracy, they could battle with peak brightness in comparison with LED screens or double-layer OLEDs. The lifetime of those shows, notably the blue natural compounds, is shorter than that of different applied sciences, which may have an effect on the general longevity of the display screen.

In abstract, single-layer OLED expertise affords splendid colour accuracy and distinction with a skinny, energy-efficient design however faces challenges with burn-in, brightness, and lifespan.

Double-layer OLED display screen expertise defined

Double-layer OLED expertise builds upon the single-layer method by introducing an extra layer of natural light-emitting compounds. This setup goals to reinforce the show’s brightness, effectivity, and sturdiness. By having two layers, the display screen can distribute the workload, probably rising the general lifespan of the show and decreasing the chance of burn-in.

The extra layer permits for extra gentle to be emitted with out considerably rising energy consumption, resulting in brighter shows which are nonetheless energy-efficient.However – that is even higher – double-layer OLEDs can enhance colour accuracy and quantity by offering a broader vary of colours and deeper colour saturation. This expertise retains the advantages of single-layer OLED, corresponding to excessive distinction ratios and suppleness, whereas making an attempt to deal with a few of its limitations. The inclusion of a second layer can, nonetheless, lead to a barely thicker show, which could be a consideration in ultra-thin gadget designs.

So, how do you want your cellphone shows? Skinny (and with a burn-in proclivity) or thick (with juicy, wealthy colours and an prolonged lifespan)?

One of many vital benefits of double-layer OLED screens is their improved longevity and resistance to burn-in, making them extra appropriate for gadgets with static photographs or interfaces. Moreover, the improved brightness ranges make these screens extra readable in direct daylight or brightly lit environments.


  • Elevated brightness and effectivity
  • Improved longevity and resistance to burn-in
  • Enhanced colour accuracy and quantity
  • Retains excessive distinction ratios and suppleness


  • Barely thicker than single-layer OLED screens
  • Probably increased manufacturing prices

In essence, double-layer OLEDs intention to reinforce brightness, colour, and sturdiness whereas sustaining some great benefits of OLED expertise, albeit on the potential value of elevated thickness and manufacturing complexity.

Single-layer vs. Double-layer OLED (for foldables)

Right here’s a query that cellphone makers will probably be asking themselves in 2025, and onwards: “Ought to we go single or twin for our subsequent folding gadget?”Single-layer OLED screens, being thinner and extra versatile, are naturally suited to the bending and flexing required in foldable telephones. Their flexibility facilitates the creation of gadgets that may be folded with out damaging the show.

Double-layer OLEDs, whereas providing improved brightness and sturdiness, current a problem attributable to their barely elevated thickness. In foldable cellphone purposes, the place each millimeter contributes to the gadget’s general bulk and foldability, this is usually a main situation.

Apple is taking notes, as regular

There’s a model that will even leap on the dual-layer OLED wagon: Apple. It’s simply that Cupertino wants a number of extra years to type issues out.

“In 2028, we anticipate the iPad Air to go OLED as properly, with the iPad Air utilizing single-stack and the iPad Professional utilizing two-stack tandem OLEDs,” mentioned Omdia researcher Kang Min-soo lately.

Properly, we hope by 2028 the iPhone will get the dual-layer OLED remedy as properly. If by that point Apple’s cellphone bends in two, nonetheless, it’s going to most likely stay with a single-layer OLED show. Not that there’s one thing mistaken with it…

It’s fascinating to see the place Samsung will take its followers in 2025 by way of show expertise. Once more, the display screen on the Galaxy S24 Extremely has confirmed to be stable (in each facet, not simply in mere toughness):

Do you care about dual-layer OLEDs?

Each the Magic 6 Final (~$1000) and the Magic 6 RSR (~$1400) aren’t low-cost. Perhaps BOE’s new dual-layer OLED show is responsible for that?

I don’t anticipate a two-stack tandem OLED in, say, the Pixel 8a, however will probably be good to see this show expertise unfold throughout extra gadgets. Yup, it’s going to include a worth, however, eh, every part is dear nowadays. Even eggs.
