Lower-refresh-rate screens generally consume less battery power than equally specced faster ones, and LG claims its so-called “Oxide 1Hz” screens lead to “48 percent more use on a single charge compared to existing solutions.” Although, what users actually experience will depend on how they use their computer and screen.
In November, BOE and Intel announced a similar 1 Hz laptop display technology that works in conjunction with Windows and Intel GPUs to automatically change refresh rates. However, the companies haven’t said when the displays might be available in devices.
Some OLED smartphones and smartwatches have been using a display tech that’s similar to Oxide 1Hz, called LTPO (low-temperature polycrystalline oxide), since 2018. LG’s so-called Oxide 1Hz brings the capability to LCD displays and laptops.
The concept behind Oxide 1Hz is also similar to dual-mode displays that have existed in gaming laptops and monitors since 2024 and that LG Display produces. However, those displays differ from Oxide 1Hz in that they require the user to press a button to quickly switch from a high refresh rate and low 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 that it will mass-produce an OLED version of Oxide 1Hz starting in 2027.
