Apple has called off a joint project with Samsung to use a Samsung-developed OLED display for a forthcoming 10.9-inch iPAD Air, according to a new report today from. The Elect Single stack refers to the current widely used OLED panel structure where red, green and blue form one emission layer.
Apple is reportedly not satisfied with the brightness levels of single stack OLED panels and is also wary of the panel’s lifespan, since consumers typically hold onto iPads for longer compared to smartphones, which have a more aggressive upgrade cycle.
Instead, Apple wants to use a two-stack tandem structure for its first OLED iPad that stacks two red, green and blue emission layers instead of just one. This doubles the brightness and extends the panel’s life by up to four times.
However, Samsung has only commercialized a single stack structure and is either not able or not willing to supply the two-stack technology, according to the report.
Profitability is also said to be a factor in Samsung’s unwillingness to provide the technology. Unless Samsung can be sure that the OLED iPad Air will be sold for a long time, preparing for the back-end module process for the products won’t be worth the cost.
There have been reports for a while now that Apple is working on plans to add OLED screens to its iPad models and originally it was said that they might appear in 2022. Now a new report from The Elec says that Apple and Samsung Display have cancelled the screen development they were working on for it, meaning that 2023 or 2024 are the earliest dates we’re likely to see an iPad with an OLED screen.
Apparently, Apple is asking for the panels to be made with double-stacked layers of pixels, which should provide higher brightness levels, but at the same time massively extends the lifetime of the screen, and can reduce the likelihood of image burn-in, which still plagues OLED screens on phones.
Burn-in is when static images that often appear on your phone become visible in a ghostly form even when someone else is on-screen. On a phone, it’s often icons from the Lock screen or the symbols in the bar at the top, since they appear very commonly, and don’t change much.
However, people upgrade their phones fairly regularly especially hardcore users who are mostly likely to suffer from burn-in so you don’t have to live with burn-in for too long, commonly (if you ever notice it at all). And it’s the same for the longevity of the screen OLED panels reach the end of their life much quicker than LCD, but still long after most phones will have headed to the great recycling plant in the sky.
But iPads aren’t replaced quickly in the same. People keep them for years and years, more like laptops. So the screen needs to last for years and years, and needs to not suffer from significant burn in during that time.
So apparently Apple is looking for OLED screens that will handle all of this better and, if it’s looking for extra brightness at the same time, it’s presumably also planning to deliver premium image quality that may well include the same awesome HDR brightness that you get in the iPhone 12 and iPhone 13.
The report says that Apple and Samsung Display (which makes most phone OLED screens on the market) couldn’t make these plans work possibly due to production problems, or possibly due to them not being profitable enough for Samsung Display to bother with. Or both.
Additionally, the report also notes that LG Display (the other huge player in OLED, and the only manufacturer of the panels in OLED TVs) has been making the kind of stacked display that Apple wants, but can’t do it in high enough quantities for Apple’s needs.
