The Short Version
LG Display is developing HMO OLED panels for Apple Watch, targeting 30–50 cm²/Vs electron mobility and a 2027 production timeline.
Apple Watch has been stuck at roughly 18 hours of battery life for years, and the reason is partly the display. LG Display is building a new screen technology called HMO, which moves electrons through the panel three to five times faster than current screens, letting the display do the same work while drawing less power. LG has already installed production equipment, with panels targeting a 2027 ship date. The catch: mass-production testing is not finished yet.
