LG Display Mass-Produces LTPO-Like 1Hz LCD Panels for Laptops, Claims 48% Better Battery Life

LG Display has begun mass-producing "Oxide 1Hz" LCD panels for laptops, bringing LTPO-like variable refresh rate technology — previously limited to OLED smartphones — to LCD displays for the first time. The company claims the panels deliver 48% more battery life compared to existing laptop displays.

The Technology

• Oxide 1Hz: LCD panels that can drop refresh rate to as low as 1Hz when displaying static content
• Battery impact: LG claims 48% more usage on a single charge vs existing solutions
• How it works: Low refresh rates consume less power when content isn't changing (reading, documents)
• Mass production: Now shipping, available in Dell's 2026 XPS laptops as base option

Context: LTPO

• LTPO (Low-Temperature Polycrystalline Oxide): Variable refresh technology used in OLED smartphones since 2018
• Smartphones/watches: Apple Watch, Samsung Galaxy S series have used LTPO for years
• Laptops: Oxide 1Hz brings this capability to LCD displays for the first time
• OLED version: LG plans to mass-produce OLED Oxide 1Hz starting 2027

Competition

• BOE + Intel: Announced similar 1Hz laptop display tech in November, working with Windows and Intel GPUs for automatic refresh rate changes — but no availability date
• Gaming dual-mode: Gaming laptops have had dual-mode displays (switchable refresh/resolution) since 2024, but require manual button press — Oxide 1Hz is automatic
