Apple is expected to finalize OLED panel approvals for the iPhone 18 Pro and Pro Max this month, with Samsung Display and LG Display likely to dominate panel supply, reports The Elec.

This year, China's BOE has reportedly been closed out of the premium tier supply chain, despite having landed some panel orders for the iPhone 17 Pro models.

The setback is said to be down to quality and yield issues with its lower-temperature polycrystalline oxide-plus (LTPO+) technology compared to its South Korean counterparts.

Indeed, it's the key upgrade at the center of the supply shake-up.

South Korean publication ETNews previously reported that the iPhone 18 Pro models will use LTPO+ display technology, which would likely be more power efficient than the current LTPO technology in the iPhone 17 series.

Such an upgrade could also contribute to longer battery life, since LPTO+ enables finer control of OLED light emission, potentially allowing the display to optimize its operation based on environmental conditions.

The ETNews report from January also mentioned that the iPhone 18 Pro models will use under-screen infrared technology from Samsung, which could enable some Face ID components to move under the display.

That could allow Apple to shrink the Dynamic Island on the iPhone 18 Pro models -- but whether it will do is seemingly still up for debate. Apple is expected to unveil the iPhone 18 Pro models in September.
