Overview

• The LTPO3 approach incorporates oxide semiconductors into both switching and drive transistors, aiming to cut the power draw of each pixel switch.
• Apple tested the oxide-based design on the Apple Watch Series 10 to validate its efficiency benefits at refresh rates as low as 1 Hz.
• Samsung and LG are expected to produce the next-generation panels, which will require significant equipment upgrades.
• A final decision on integrating LTPO3 for at least one 2027 iPhone model is due by Q3 2025.
• The ultra-thin iPhone 17 Air is unlikely to feature LTPO3, leaving its battery life more vulnerable until newer models adopt the technology.
