What is LTPO?
Low-Temperature Polycrystalline Oxide - a display backplane technology enabling variable refresh rates.
LTPO (Low-Temperature Polycrystalline Oxide) is an advanced display backplane technology that enables variable refresh rate displays. It combines the benefits of LTPS (Low-Temperature Polycrystalline Silicon) and IGZO (Indium Gallium Zinc Oxide) transistors.
Key Benefits of LTPO
- Variable Refresh Rate: Can dynamically adjust from 1Hz to 120Hz (or higher) based on content.
- Power Savings: Drops to 1Hz for static content like always-on display, saving up to 20% battery.
- Smoother Experience: Ramps up to high refresh rates for scrolling and gaming.
How It Works
LTPO technology uses oxide transistors that can maintain their state with minimal power, allowing the display to hold an image at very low refresh rates without visible flickering.
Phones with LTPO
- Apple iPhone 13 Pro and newer Pro models
- Samsung Galaxy S21 Ultra and newer flagship models
- OnePlus 9 Pro and newer
- Google Pixel 6 Pro and newer
LTPO is a key technology for maximizing battery life in phones with high refresh rate displays.
