LG Launches World's First 1 Hz to 120 Hz LCD Laptop Display

LG Display has announced the commencement of mass production of the world's first LCD laptop panel capable of a variable refresh rate ranging from 1 Hz to 120 Hz. This groundbreaking technology utilizes an Oxide TFT display that minimizes power leakage during low refresh rate operations. The panel intelligently detects screen activity, automatically adjusting the refresh rate based on user interaction. For instance, it operates at 1 Hz during static tasks like reading emails and switches to 120 Hz for dynamic activities such as gaming or streaming videos.

The new display technology is designed to enhance battery efficiency significantly, boasting a 48% increase in usage time compared to existing solutions. This improvement is particularly relevant as laptops increasingly become essential for mobile computing. The Oxide 1 Hz technology is expected to be integrated into Dell's premium XPS laptop lineup, which was unveiled at CES 2026. The base model will feature a resolution of 1920 x 1200, while higher-end options will include OLED displays with a refresh rate range of 20 Hz to 120 Hz, foregoing the 1 Hz capability.

The introduction of the 1 Hz-capable display marks a shift in laptop display manufacturing towards energy-efficient solutions. Other companies, including Intel and BOE, are also developing similar displays using Low-Temperature Polycrystalline Oxide (LTPO) technology, which employs AI algorithms to optimize refresh rates based on user behavior. This trend is particularly significant as the demand for laptops with extended battery life grows, especially in light of increasing power consumption from AI-driven applications.
