Understanding LTPO Display Technology in Smartphones

How LTPO Technology Works

LTPO is unique because it combines two separate backplane technologies into one system:

• LTPS (Low-Temperature Polycrystalline Silicon):
  Provides high-speed switching, enabling fast refresh rates like 120 Hz for smooth gaming and scrolling.

• IGZO (Indium Gallium Zinc Oxide):
  Offers very low power consumption, making it ideal for static content like Always-On Display (AOD).

By merging both, an LTPO display can dynamically adjust its refresh rate based on what you’re doing—dropping as low as 1 Hz for still images and scaling up to 120 Hz when needed for motion-heavy content.

 Key Benefits of LTPO Displays

⚡ Dynamic Refresh Rate Adjustment

LTPO panels automatically shift between refresh rates depending on usage, optimizing performance only when required. This avoids unnecessary battery drain.

🔋 Better Power Efficiency

Because the refresh rate drops during low-activity moments, LTPO displays can reduce screen-related power consumption by up to 30–40%, improving overall battery life.

🎮 Smoother Visual Performance

High refresh rates feel fluid and responsive, enhancing gaming, scrolling, and animations.

🖼 Improved Always-On Display (AOD)

With the ability to drop to 1 Hz, LTPO displays maintain features like Always-On Display with minimal battery impact.

 LTPO in OPPO Smartphones

Several OPPO flagship models—especially within the OPPO Find X series and Reno Pro series—feature LTPO-enabled 120 Hz AMOLED displays.

ColorOS intelligently manages these dynamic refresh rates, ensuring a balance between high-performance visuals and longer battery life.
