LG Display said Sunday it has begun mass producing an LCD laptop panel capable of adjusting its refresh rate from 1 hertz (Hz) to 120 Hz depending on the usage environment.

The panel, powered by Oxide 1Hz technology, operates at a minimum refresh rate of 1 Hz when the screen remains static during tasks such as email, e-book reading and document viewing. It automatically switches to a high refresh rate of up to 120 Hz when users move the mouse or start video content or games with rapid screen changes.

Refresh rate refers to how many times a panel updates the image on the screen per second. A higher refresh rate reduces screen flicker while delivering smoother and clearer motion with lower input lag. However, maintaining a high refresh rate for a still image leads to unnecessary power consumption, as the same image continues to be refreshed.

LG Display said the Oxide 1Hz panel applies oxide material, which has the lowest power leakage in low refresh rate operation, to the display’s thin film transistors. It also developed new circuit algorithms and panel design technology for the panel.

The company expects the panel to extend battery life by more than 48 percent compared to existing panels. In laptops, battery efficiency is a key factor influencing purchasing decisions, and with power consumption rising due to increased artificial intelligence workloads, laptops equipped with Oxide 1Hz technology are expected to improve user convenience.

Laptop panels using Oxide 1Hz will be supplied to Dell’s XPS premium laptop series. Dell unveiled a new XPS model equipped with the panel at CES 2026 in January.

LG Display said it will apply Oxide 1Hz technology to OLED panels under the goal of beginning mass production in 2027.

“With the successful mass production of the Oxide 1Hz panel, we will widen the technological gap with competitors and further strengthen our position as a technology-driven company,” an LG Display official said.
