LG’s next-gen 120Hz display promises a huge jump in laptop battery life

LG Display has begun mass production of a new LCD laptop panel featuring Oxide 1Hz technology, which automatically adjusts the refresh rate between 1Hz and 120Hz based on on-screen activity. This technology is being mass-produced for the first time in laptops, and the battery life gains are genuinely impressive.

But we have had a 120Hz refresh rate display for a long time, so how can it be the first time, you might ask? Well, not all 120Hz displays are the same. Most laptop displays dynamically refresh the screen somewhere between 25Hz and 120Hz, depending on the content being displayed. 

This LG panel can drop down to 1Hz when your screen is mostly still, like when you are reading emails or going through a research paper, and ramp up to 120Hz when you are watching a sports event or playing a game. 

Why does the 1Hz refresh rate even matter?

Refresh rate refers to the number of times your screen redraws itself per second. A higher refresh rate produces smoother visuals, making it ideal for fast-moving content.

The problem is that most laptop screens run at high refresh rates all the time, or cannot refresh down to a low enough number that can have a meaningful impact on the battery life, even when nothing on the screen is moving. That is wasted power, and your battery pays for it.

LG Display developed its own circuit algorithms and new materials to make the low-power mode actually work. The result is a 48% improvement in battery life compared to existing solutions. That is a vast improvement that will extend your laptop’s battery life. 

Who gets it first?

LG Display is first supplying these panels to Dell for its premium XPS lineup. Dell has already shown off new XPS models using this panel at CES 2026 back in January. LG Display is also planning a 1Hz OLED version using the same technology, set to begin mass production in 2027.
