Apple Rumored to Develop "LTPO+" OLED Panels for iPhone 18 Pro/Pro Max

The primary distinction between regular iPhone models and the “Pro” versions lies in Apple’s annual use of LTPS and LTPO technologies. For the more premium devices, the introduction of LTPO means better power efficiency and improved color reproduction, not to mention support for ProMotion, enabling a smooth 120Hz refresh rate.

However, this differentiation may disappear next year, as all iPhone 17 models are rumored to feature LTPO OLED panels. Yet, there are whispers that Apple will introduce a new display technology called “LTPO+” the following year. This new feature might give customers another reason to spend more on the iPhone 18 Pro or iPhone 18 Pro Max.

This rumor comes from Jukanlosreve, who claims that independent analyst and consulting firm Omdia predicts Apple will unveil LTPO+ technology in two years. While the latest post on X does not detail specific features, the insider suggests that LTPO+ is still under development. When it enters production, it is expected to boast enhanced attributes compared to standard LTPO, including improved efficiency.

Given that Samsung and LG are Apple’s current suppliers for iPhone displays, providing LTPO panels annually, these two South Korean manufacturers will likely be responsible for bringing this technology to market. It’s worth noting that Samsung initially declined to mass-produce tandem OLED panels for Apple’s M4 iPad Pro models due to profitability concerns, only agreeing if order volumes were sufficiently high.

Although the manufacturing giant eventually complied, the setback led to delays in the product launch. If Apple cannot persuade Samsung and LG to invest in R&D and establish separate production lines for these advanced OLED displays—which could cost billions of dollars to achieve—LTPO+ might face similar delays. Should obstacles arise in the production timeline, the iPhone 18 Pro and iPhone 18 Pro Max may have to rely on conventional LTPO technology.
