Oxide 1Hz Screens: 1–120 Hz for Laptops

# Mass Production of Oxide 1Hz Laptop Screens: From 1 to 120 Hz

LG Display has started mass production of LCD displays with Oxide 1Hz technology for laptops. The panels automatically adjust the refresh rate: 1 Hz for static content, 120 Hz for dynamic tasks like gaming or video. This reduces power consumption without sacrificing performance.

The Oxide 1Hz technology uses oxide semiconductors (TFT based on IGZO or similar materials), providing low leakage current in low-frequency mode. For static images—text, documents, interfaces—pixels update infrequently, minimizing battery drain.

Power Savings and Practical Performance

Switching to 1 Hz boosts laptop battery life by 48%. The calculation is based on typical scenarios: office work, reading, browsing. In high-motion modes—streaming, gaming—the rate ramps up to 120 Hz for smoothness.

• Automatic switching: The system analyzes content type and motion.
• Compatibility: Integration with OS drivers (Windows, Linux) via VRR-like mechanisms.
• Resolution and sizes: Suitable for 14–16" XPS-class panels, QHD+.
• Developer benefits: API for customization in embedded systems or custom OSes.

Tests show stability: switching delays <16 ms, flicker-free.

Integration with Dell XPS and OLED Plans

First shipments are going to Dell for the XPS lineup. At CES 2026, prototypes with Oxide 1Hz were demoed: 13, 14, 16-inch models. The panels are compatible with USB4/Thunderbolt and support HDR400+.

Starting in 2027, LG Display will launch OLED versions with the same technology. OLED will enable even greater power savings thanks to self-emissive pixels and perfect blacks in 1 Hz mode.

Key for engineers: Panel drivers use LTPS/Oxide hybrid, compatible with MIPI D-PHY v2.0. Controller requirements—support for adaptive sync.

Environmental Aspects of the Technology

Oxide 1Hz fits into LG's project to reduce CO2 emissions. The goal is a 10% reduction during product use. Power savings directly cut the carbon footprint: fewer charging cycles, less strain on power grids.

Key Points:

• Automatic drop to 1 Hz saves 48% battery on static content.
• 120 Hz for video/games without lag, switching <16 ms.
• Shipments to Dell XPS, OLED from 2027.
• Eco-goal: -10% CO2 thanks to lower consumption.
• Ideal for mid/senior devs: customization via API.

Developers can test on LTPO/Oxide emulators or real samples from suppliers.
