What everybody must find out about Tandem OLED and WOLED TVs

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

Panel expertise often is the most complicated facet in the mean time. For a very long time, all you needed to know was that OLED was la crème de la crème. Now, nonetheless, it isn’t 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 may be extra acquainted than you’d anticipate.

What’s WOLED?

An previous acquainted face that also has a spot

WOLED is brief for white OLED (organlc light-emitting diode). Whereas that time period may really feel new, it is probably solely as a result of it wasn’t necessary to differentiate earlier than. The reality is that should you’ve owned any sort of OLED TV previously, it was most likely WOLED-based, since shopper 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 mild by means of pink, inexperienced, and blue colour filters, producing the colours you see in every pixel. However the outcome is not very shiny, or no less than not robust sufficient for regular viewing situations. You’d have to look at in a dim room — daylight viewing could be out of the query.

WOLED’s resolution to it is a fourth, unfiltered white subpixel, which boosts brightness to affordable ranges. The truth is, trendy 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 flexibility 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 hardly ever shut off fully.

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 mild, which is definitely extra intense than white, regardless of the best way your mind may understand it. This passes by means of the quantum dots, which emit completely different colours based mostly on their dimension. The result’s much more spectacular colour saturation versus WOLED. Notably, QD tech has since unfold elsewhere, for example 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 referred to as MLA (micro lens array) OLED. This helped focus mild 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 had 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 probably Apple’s 2024 iPad Professional. Up till that time, the corporate had solely used LCDs for iPads. You can too discover a tandem show in 2025 Pro fashions.

Apple’s model of the expertise actually stacks two panels collectively. This may 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 shiny as newer TVs, in fact, however a pill is normally not more than a few ft away out of your eyes. Most TV viewers are sitting no less than 3 times as distant, and the inverse-square legislation dictates that depth diminishes as a sq. of the space from a light-weight supply. You really want larger 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 colour 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 dangerous information right here. The excellent news is that Major RGB Tandem OLED can 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 colour gamuts, as much as 99.5% and 83% respectively. Your eye most likely will not discover the additional colour shades, however this does put LG’s tech roughly on par with QD-OLED.

The dangerous 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. On condition that some similarly-sized WOLED units are promoting for $1,200 or much less, you need to be deeply obsessive about image high quality to justify the leap. The financial savings could possibly 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 funds, this may be a difficulty, provided that the perfect QD-OLED TVs are already as shiny as tandem OLED.

The elephant within the room

Some notes on the longer term

In the end, all types of OLED could also be on their method out. Do not get me mistaken — any mannequin you purchase at the moment goes to look superb, and final a really very long time so long as you preserve it correctly. However throughout the subsequent few years, OLED could possibly 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 prime of this, they ship near-perfect colour accuracy.

The true catch in the mean time is worth. Each codecs are so new and costly that should you may even discover a set, it is liable to price you tens of hundreds of {dollars} — Samsung’s 115-inch micro RGB set is $30,000. It will take smaller sizes and mass manufacturing to deliver costs all the way down to affordable ranges.

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