LG Display mass-produces Oxide 1Hz laptop LCD panel

On March 22, LG Display announced that it would be the first in the world to mass-produce laptop LCD panels equipped with "Oxide 1Hz" technology.

According to reports, the panel is characterized by the ability to automatically adjust the refresh rate according to screen conditions, ranging from a minimum of 1Hz to a maximum of 120Hz. When the screen displays static images, the refresh rate will automatically be reduced to 1Hz, and it can be increased to 120Hz when needed. For example, when performing operations based on static images such as checking emails, reading e-books, or research papers, the panel will run at a minimum refresh rate of 1Hz; while when playing streaming content such as movies and sports events, or running games with frequent screen changes, it will run in a high refresh rate mode of up to 120Hz.

To realize this world-first technology, LG Display independently developed circuit algorithms and panel design technology, adopted new materials, and applied low-power oxide thin film transistors (TFTs) in the low refresh rate range. The company says this technology can extend battery life by more than 48% compared to existing models.

LG Display will supply its Oxide 1Hz laptop panels to global PC manufacturer Dell for use in Dell's flagship high-end XPS series. Dell already exhibited a new XPS model equipped with this panel at CES 2026 in January this year.

In the future, LG Display plans to expand this technology to OLED panels. Related research and development work is currently underway, with the goal of achieving mass production in 2027. The company also plans to launch a parallel project to reduce use-phase carbon emissions by up to 10% by expanding the use of energy-saving technologies.
