1. Apple is exploring the use of IZO cathode technology for a more advanced, 4-side bending OLED panel for 2028 iPhones.
2. LG Display is investing heavily (~$770M) in OLED infrastructure to develop this new transparent electrode tech, likely for early R&D and eventual mass production.
3. Samsung Display is considering new factory lines to accommodate the required equipment, due to current limitations in their existing lines.
New Developments in OLED Technology for Future iPhones
Recently, industry insiders, like ETNews, reported that Apple is making moves to improve their display tech, especially for their next big thing. They chatting with South Korean display companies to develop a new 4-side bending OLED panel, set for release in 2028. This technology could turn the actual shape and look of future iPhones into something more flexible and sleek, offering a higher level of perfection.
Innovations in Transparent Electrode Materials
This new design involves curving all four edges of the screen, which is a complex engineering feat. What’s more interesting is that Apple aims to make this possible by using a new cathode material—most likely IZO (Indium Zinc Oxide). The cathode, as you may know, is a crucial part of OLEDs, letting light pass through in top-emission displays. Using a more transparent cathode should greatly enhance the display’s clarity at the curved edges, making the phone look sharper and more seamless. This isn’t just about style, it’s about tech and functionality, and Apple sure is pushing hard for it.
Manufacturers Gear Up for the Transition
Samsung and LG, Apple’s main OLED producers, are already preparing for this upgrade. LG seems to be ahead with a significant investment of about 770 million dollars, aiming to establish new OLED infrastructure. This investment targets the development and later mass production of these advanced panels, especially focusing on the delicate TCO sputtering equipment needed for low-damage deposition. They plan to start R&D first, then scale up production when all is ready.
Challenges and Industry Shifts
Meanwhile, Samsung Display is considering whether they should buy new factory lines. But their current facilities are somewhat limited—they either lack the space or the flexibility needed for the new equipment. Therefore, a new dedicated line appears more likely. Apple’s strong push to accelerate this transition, however, makes the Korean companies feel the need to spend sooner on factories so they can meet ultra-high standards set by Apple. This race to develop these flexible, transparent displays is on, and everyone is gearing up for the 2028 release date.
