Screens with lower refresh rates generally consume less battery power than similarly specified faster screens, and LG claims its so-called “Oxide 1Hz” screen “uses up to 48 percent more on a single charge than existing solutions.” However, what users actually experience will depend on how they use their computers and screens.
In November, BOE and Intel announced a similar 1Hz laptop display technology that works in conjunction with Windows and Intel GPUs to automatically change refresh rates. However, the companies have not said when the display may be available in the device.
Some OLED smartphones and smartwatches since 2018 have been using a display technology that is similar to oxide 1Hz, called LTPO (low temperature polycrystalline oxide). LG’s so-called oxide brings the capability to 1Hz LCD displays and laptops.
The concept behind Oxide 1Hz is also similar to the dual-mode displays that are present in gaming laptops and monitors from 2024 and manufactured by LG Display. However, those displays differ from Oxide 1Hz in that they require the user to press a button to switch from a higher refresh rate and lower resolution to a lower refresh rate and higher resolution and are targeted at gaming.
Dell’s 2026 XPS laptops currently offer Oxide 1Hz displays as a base option.
LG said it will mass produce the OLED version of Oxide 1Hz from 2027.
