What everybody must learn about Tandem OLED and WOLED TVs

I’ve stated it elsewhere, however I generally pity folks coming into the home theater area in 2026. Whereas the know-how is healthier than ever — a $500 TV would possibly blow away a $1,000 mannequin launched just some years in the past — there’s such a lot of phrases and standards to know that procuring may be intimidating. HDR alone has 4 main requirements, solely two of that are liable to be necessary going ahead.

Panel know-how stands out as the most complicated facet for the time being. For a very long time, all you needed to know was that OLED was la crème de la crème. Now, nonetheless, it is not solely being challenged by requirements like MicroLED, however enhanced variations of itself. On this piece I will distinguish between two applied sciences, WOLED and tandem OLED, each of which is perhaps extra acquainted than you’d anticipate.

What’s WOLED?

An outdated acquainted face that also has a spot

WOLED is brief for white OLED (organlc light-emitting diode). Whereas that time period would possibly really feel new, it is doubtless solely as a result of it wasn’t necessary to tell apart earlier than. The reality is that in case you’ve owned any type of OLED TV prior to now, it was most likely WOLED-based, since client options to WOLED solely emerged in 2022. Extra on that in a second.

The gist of WOLED is that by itself, a real vanilla model of OLED would not be nice in your front room. This most elementary tech passes white gentle by way of pink, inexperienced, and blue shade filters, producing the colours you see in every pixel. However the outcome is not very vibrant, or no less than not robust sufficient for regular viewing situations. You’d have to observe in a dim room — daylight viewing can be out of the query.

WOLED’s resolution to it is a fourth, unfiltered white subpixel, which boosts brightness to cheap ranges. In actual fact, fashionable WOLED TVs are highly effective sufficient that in scenes with robust highlights, the whites may be blinding. That is enhanced by the first benefit of OLED: superior distinction, created by the power to show particular person pixels on and off. Blacks on an OLED are pure. Most LCDs can solely get near black, since they’re depending on LED backlights which can be not often shut off utterly.

What occurred in 2022 was the emergence of Samsung’s QD-OLED, the QD standing for quantum dot. This differs from WOLED by beginning with blue gentle, which is definitely extra intense than white, regardless of the best way your mind would possibly understand it. This passes by way of the quantum dots, which emit totally different colours based mostly on their dimension. The result’s much more spectacular shade saturation versus WOLED. Notably, QD tech has since unfold elsewhere, as an illustration showing on Sony TVs.

Different corporations have caught with variations of WOLED, nonetheless, together with LG, which tried to compete with QD-OLED utilizing one thing known as MLA (micro lens array) OLED. This helped focus gentle output. Certainly LG’s third-generation OLED units can obtain 3,000 nits of peak brightness, sufficient to be plainly seen in noon solar. Its first-gen OLED merchandise have been capped at simply 500 nits.

So what’s tandem OLED, and what makes it higher?

For many individuals, myself included, the primary they’d ever heard of tandem OLED was doubtless Apple’s 2024 iPad Professional. Up till that time, the corporate had solely used LCDs for iPads. It’s also possible to discover a tandem show in 2025 Pro fashions.

Apple’s model of the know-how actually stacks two panels collectively. This would possibly sound ridiculous, however the result’s amplified brightness, as much as 1,600 nits peak — about 1,000 greater than the LCD-based iPad Air. That is not as vibrant as newer TVs, after all, however a pill is normally not more than a few toes away out of your eyes. Most TV viewers are sitting no less than 3 times as distant, and the inverse-square regulation dictates that depth diminishes as a sq. of the space from a lightweight supply. You really need increased brightness the additional away you’re, in different phrases.

There are different methods of going tandem. For its fourth-gen OLED TVs, LG has developed one thing dubbed Major RGB Tandem OLED. This separates a yellow layer (used within the third gen) into separate pink and inexperienced layers, elevating peak brightness to 4,000 nits, and total shade brightness to 2,100. You are not getting a number of sandwiched panels. As a substitute, there are merely 4 layers within the stack, the opposite two being blue.

There’s each good and unhealthy information right here. The excellent news is that Major RGB Tandem OLED may also be present in some Panasonic and Philips TVs, and with all three manufacturers, the result’s a noticeably brighter image than earlier efforts — it doesn’t matter what you are watching. LG specifically claims decrease energy consumption, in addition to wider protection of the DCI-P3 and Rec.2020 shade gamuts, as much as 99.5% and 83% respectively. Your eye most likely will not discover the additional shade shades, however this does put LG’s tech roughly on par with QD-OLED.

The unhealthy information is that there are only a few tandem OLED TVs in the marketplace, they usually’re not low-cost. As of this writing, the LG G5 begins round $1,800 for a 55-inch mannequin, and the Panasonic Z95B is $2,000. Provided that some similarly-sized WOLED units are promoting for $1,200 or much less, it’s important to be deeply obsessive about image high quality to justify the leap. The financial savings might be put in direction of a soundbar, a sport console, or just paying off your payments.

Relative to QD-OLED, there can also be barely inferior element in near-black shades. For a purist with a fats finances, this is perhaps a difficulty, on condition that the perfect QD-OLED TVs are already as vibrant as tandem OLED.

The elephant within the room

Some notes on the long run

Finally, all types of OLED could also be on their method out. Do not get me improper — any mannequin you purchase in the present day goes to look wonderful, and final a really very long time so long as you keep it correctly. However throughout the subsequent few years, OLED might be supplanted by MicroLED and micro RGB, which use microscopic pink, inexperienced, and blue LEDs. These merge the precision of OLED with the brightness and longevity of LCD/LED panels. On high of this, they ship near-perfect shade accuracy.

The actual catch for the time being is worth. Each codecs are so new and costly that in case you may even discover a set, it is liable to value you tens of 1000’s of {dollars} — Samsung’s 115-inch micro RGB set is $30,000. It should take smaller sizes and mass manufacturing to carry costs all the way down to cheap ranges.

When you already personal a WOLED TV and also you prefer it, then, you should not be in a rush to purchase a tandem OLED product. Just a little endurance may land you one thing higher, assuming these manufacturing hurdles are overcome.
