I've been following the display tech world closely, and the buzz around tandem OLED is definitely getting louder. Word on the street is that LG Display is pushing hard for Apple to adopt this technology in iPhones as early as 2028. Now, LG Display isn't just talking; they're backing it up with a hefty patent portfolio in tandem OLED tech.

What exactly is tandem OLED? Instead of a single layer that emits light, it uses two. This clever stacking trick promises brighter screens, longer lifespans for our devices, and, crucially, better battery efficiency. We all know how much we crave that extra hour or two of screen time, right?

Apple's already dipping its toes into this, using tandem OLED in the latest M4 iPad Pro. LG Display snagged a big chunk of that panel supply, proving they can deliver. But it's not just Apple. Chinese smartphone maker Honor is already using tandem OLEDs, showing that this tech isn't just a pipe dream – it's viable in today's market.

However, mass production could be a hurdle. Stacking those two emission layers isn't as simple as it sounds, and it could slow things down. LG Display is apparently gearing up to invest in solutions to tackle these potential bottlenecks. I believe that's a smart move; preparation is key.

It seems LG Display pitched a simplified version of tandem OLED to Apple some time ago. If Apple does jump on board, they will want to secure production from multiple suppliers to avoid shortages and to negotiate better prices. If that's the case, we might see Samsung and BOE joining the party, too. Of course, it's still early days, and Apple's plans could always shift. But I'm excited about the potential improvements in display technology that we might see in the coming years.
