Tandem OLED is OLED's latest weapon in holding off MicroLED, QDEL

Tandem OLED technology is gaining traction in the display market, particularly after Apple's introduction of it in the iPad Pro. This technology features two layers of red, green, and blue (RGB) organic light-emitting layers, allowing for higher brightness levels while reducing power consumption and the risk of burn-in. While Tandem OLED is being adopted in smaller devices like smartphones and laptops, its application in larger displays, such as TVs, faces challenges due to different manufacturing processes. Current OLED technologies, including LG's WOLED and Samsung's QD-OLED, utilize various tandem structures but do not employ the same RGB stacking as Tandem OLED. Experts suggest that while Tandem OLED offers advantages, the existing brightness levels in modern OLED TVs may limit its incentive for high-end applications. The manufacturing incompatibility between small and large OLED displays further complicates the potential for Tandem OLED in the television market.

- Tandem OLED features dual RGB layers for improved brightness and reduced power consumption.

- Apple popularized Tandem OLED with its iPad Pro, leading to broader adoption in consumer electronics.

- The technology faces manufacturing challenges that limit its use in larger displays like TVs.

- Existing OLED technologies already provide significant brightness, reducing the need for Tandem OLED in high-end TVs.

- Different manufacturing processes for small and large OLED displays hinder the compatibility of Tandem OLED structures.

I thought MicroLED was not really ready to compete outside a TV-sized form factor due to the difficulty & costs to manufacture it at competitive resolution density for phones/tablets? Has that changed substantially since Apple cancelled it's MicroLED project for the Apple watch?

What's annoying is that this tech already existed for LCD screens. It supposedly had deep black that OLED brings but at LCD prices. If the quality is similar / no better, it's frustrating to see tandem tech never made it out of China.

I don't have much to add to this conversation except that what a lot of people don't realize it that 2k, 4k, or 8k, tv means very little in terms of how nice the picture looks. Yes to a point that is important but I always tell people the panel technology is way more important. Some TV's look absolutely lifelike, maybe beyond life like and some sort of hyper-reality. It is like a massage on your eyes watching things on a superior TV. But those TV's cost a lot. A brand I found that is very good for the cost is the HiSense ULED TV's. Costco has them. I love the picture for the affordable cost. Not the best but pretty great. I have an led monitor beside my HiSense TV, both hooked up to my pc and I ran a pure black YouTube video on both side by side and the difference is huge. The led monitor looks grey and is clearly lit up from the back light. The HiSense is absolutely pitch black dark zero light emissions. There is no real point to this post other then to say I am happy with my TV, it definitely is great for the cost.

I love OLED panels and their amazing color reproduction, but I'll never buy another device that uses them ever again if I can help it. My current laptop developed pretty horrific burn-in after just a couple years of regular use, and there wasn't really anything that could be done about it, as the burn-in is comprised entirely of my taskbar and the UI elements of my web browser which is far and away my most used program / application and likely is for the majority of other laptop users as well. I'm sure they're fine for TVs where content is played "Full screen" 99% of the time, but for phones or PCs where there are common OS or web browser UI elements displayed on the screen the majority of the time the user is using their device, they just don't make sense.

All I have to say is that the tandem oled on my ipad pro still, everytime I use it, makes me wow. It is an absolute pleasure to look at and watch things on. It feels like I'm watching real life and I love it.

>"Once blue PHOLED finally becomes available in 2025 or 2026, most display makers will integrate them in their OLED displays (single or tandem) and deliver further improvement in lifetime, brightness, and efficiency," Virey said.

This is much more important improvement than Tandem OLED. Although I dont think I could see that on an iPhone before 2030 judging from how slow Apple adopt technology.
