LG reveals new 1hz LCD display: what that means for your next laptop

LG Display has announced that it's the "world's first" producer of LCD panels for laptops featuring the company's "Oxide 1hz" technology. If the company's claims hold up, these displays could be a massive improvement in power efficiency for your next computer, possibly making the best laptops for battery life even better.

Oxide 1Hz is a feature that detects the "usage environment" and adjusts the refresh rate, down to 1Hz and up to 120Hz. For example, if you're reading emails or documents, the display will operate at a lower refresh rate. However, if you're gaming or watching movies, it can ratchet up to 120Hz.

If you're unfamiliar, the refresh rate of your display refers to how often the screen is redrawn per second. The higher the number, the less your screen flickers, making for smoother visuals.

Here's a more in-depth explanation from Intel, if you're curious. It also affects your TVs, though the rates there can go much higher.

However, the drawback of running your display with a higher refresh rate means that it also hits your battery harder.

LG Display claims that the new Oxide 1Hz panel dramatically improves battery efficiency; "48% more use on a single-charge." The company also promises that an OLED version of Oxide 1Hz will launch in 2027.

Try it on a Dell first

During CES 2026, Dell announced the return of its XPS line with new 14 and 16-inch versions of its premium laptop. There are two display variants: an OLED one or a 2K LCD display.

We reviewed the Dell XPS 14 OLED version, which lasted for an impressive 12 hours and 23 minutes in our lab tests. However, Dell promises a whopping 27 hours of battery life in the 2K variant.

For comparison, last year's Dell 14 Premium lasted only 8 hours and 16 minutes in our testing.

For this year's model, it is a cumulative effect. Between LG's new panel and the upgraded 900ED battery, you're getting massive improvements in power efficiency.

For now, it appears the Oxide 1Hz will only be available on the Dell XPS lineup. We reached out to LG for clarity on whether the panel will arrive on other laptops, including LG's own PCs like the recently revealed LG Gram Pro 17.
