LG Display Begins Mass Production of 1 Hz LCD Laptop Screens

LG Display has announced that it is now mass-producing laptop displays capable of automatically adjusting their refresh rates from 1 Hz to 120 Hz, depending on the content being displayed. The company claims to be the first in the industry to produce these 1–120 Hz screens, which are designed to improve battery life.

According to LG's announcement, these LCD screens, referred to as Oxide 1Hz, operate at a refresh rate of 1 Hz when a static image is detected on the screen. When dynamic content is displayed, the refresh rate can increase to as high as 120 Hz. LG has indicated that it developed proprietary circuit algorithms and panel design technology, along with new materials that minimize power leakage during low-refresh-rate operations.

When performing tasks that primarily involve static images—such as reading emails, e-books, or research papers—the Oxide 1Hz panel functions at its lowest refresh rate of 1 Hz. In contrast, it utilizes the higher refresh rate of up to 120 Hz for activities like streaming videos or gaming, which involve frequent screen changes. LG asserts that its Oxide 1Hz screens can provide up to 48 percent more usage on a single charge compared to existing display technologies, although actual performance will vary depending on user behavior.

In November, BOE and Intel revealed a similar 1 Hz laptop display technology that synchronizes with Windows and Intel GPUs for automatic refresh rate adjustments. However, they have not yet disclosed when their displays will be available in consumer devices.

Since 2018, some OLED smartphones and smartwatches have utilized a comparable display technology known as LTPO (low-temperature polycrystalline oxide). LG's Oxide 1Hz technology extends this capability to LCD displays and laptops.

The Oxide 1Hz technology concept is also reminiscent of existing dual-mode displays in gaming laptops and monitors, which LG Display has been producing since 2024. However, those displays necessitate user intervention to switch between high refresh rates and lower resolutions, focusing primarily on gaming applications.

Currently, Dell's 2026 XPS laptops feature Oxide 1Hz displays as a standard option. LG has also announced plans to begin mass production of an OLED variant of the Oxide 1Hz display in 2027.
