LG claims its new 1-120 Hz auto-refresh rate LCD display for laptops extends battery life by 48% and helps the new Dell XPS hit 31 hours

LG has announced a new LCD panel technology for laptops it claims is dramatically more efficient than existing panels. Known as "Oxide 1 Hz", LG Display says it, "automatically switches the refresh rate down to 1 Hz when the screen is static and up to 120 Hz when needed."

The result is, "dramatically improved battery efficiency, including 48% more use on a single charge compared to existing solutions." That is slightly odd language which begs the question of what, exactly, the "48% more use on a single charge" claim actually means.
