Apple is finalizing its supply chain for the upcoming iPhone 18 Pro and Pro Max, and the latest reports from the South Korean publication The Elec confirm that global tech giants Samsung Display and LG Display have secured a complete lock on the high-end OLED panels. Meanwhile, China’s BOE has once again hit a technical wall, failing to meet Apple’s rigorous standards for its Pro lineup.
As of this month, Apple is expected to officially approve the production results for these panels, ensuring that mass manufacturing can begin in time for the traditional September launch.
The Power of LTPO+ Technology
The primary reason for the shift back to a South Korean duopoly is the debut of LTPO+ (Low-Temperature Polycrystalline Oxide Plus) technology. While standard LTPO has been around since the iPhone 13 Pro, this Plus version is far more sophisticated:
- Granular Power Control: Unlike older screens, LTPO+ uses oxide for both switching and driving transistors. This allows the phone to adjust the electrical current sent to the pixels with extreme precision.
- Battery Efficiency: By optimizing how the panel operates based on the user’s environment, the iPhone 18 Pro should see a noticeable jump in battery life.
- Burn-in Resistance: These new panels are less susceptible to image retention, ensuring the display remains crisp even after years of heavy use.
Why BOE Missed the Cut
Despite providing some panels for the standard iPhone 17 and even small batches for the 17 Pro, BOE has struggled with quality and yield issues—the percentage of manufactured panels that actually pass inspection. Apple requires massive, stable volumes for its flagship models, and BOE simply hasn’t proven it can mass-produce LTPO+ at the same quality level as Samsung or LG.
Industry insiders suggest that Apple isn’t cutting ties with BOE entirely, but rather using them as a bargaining chip. By keeping BOE in the mix for older or entry-level models (like the iPhone 16 or 17e), Apple can pressure Samsung and LG to keep their prices competitive.
The Production Outlook
The gap between the Korean suppliers and their Chinese rivals remains massive. Estimates for 2026 suggest:
- Samsung Display: 146 million units
- LG Display: 82 million units
- BOE: 35 million units (mostly for older or refurbished models)
With rumors also swirling that the iPhone 18 Pro may feature under-display infrared technology to shrink the screen notch, the technical barrier for display manufacturers is higher than ever. For now, if you want the absolute best screen Apple has to offer, it’s almost certainly coming from a South Korean factory.
