LG Display is leading the premium laptop panel market by maximizing a differentiated customer experience with the world's top-tier, cutting-edge technology.
LG Display will begin mass production of the world's first laptop LCD panel featuring the "Oxide 1Hz" technology. The "Oxide 1Hz" panel intelligently detects how a user is using a laptop and automatically switches the refresh rate from 1Hz up to a maximum of 120Hz.
For example, when the screen is still for static tasks such as checking email, e-books, or papers, it operates in the lowest refresh rate mode of 1Hz. When a user moves the mouse or starts video content such as OTT, movies, or sports, or begins a game with frequent on-screen changes, it automatically switches to the high refresh rate mode of up to 120Hz.
Refresh rate refers to how many times per second a screen is redrawn. The higher the refresh rate, the less flicker and the smoother and clearer the display. On the other hand, maintaining a high refresh rate on a static screen requires continuously generating the same frames, which wastes power due to circuit operation.
In response, LG Display developed a panel that flexibly adjusts the refresh frequency according to on-screen changes to manage power efficiently, achieving the world's first mass production.
To mass-produce the "Oxide 1Hz" panel, LG Display independently developed circuit algorithms and panel design technologies and discovered and applied new materials. In this process, it completed a high-efficiency display by applying an oxide semiconductor with the least power leakage in low refresh-rate operation to the display TFT (Thin Film Transistor).
Using this can dramatically improve battery efficiency, including extending battery life by more than 48% compared with existing models.
For laptops, given that mobility is a key purchase factor, extending usage time with a high-efficiency battery is expected to significantly enhance mobility and improve consumer convenience. In addition, as AI computation tasks have recently increased and power consumption has risen, laptops featuring the "Oxide 1Hz" technology are expected to draw even more attention.
Laptop panels featuring LG Display's "Oxide 1Hz" technology will be supplied for the highest-spec premium line "XPS" from the global PC maker Dell. Dell unveiled new "XPS" models equipped with this panel at CES 2026 in Jan.
Going forward, LG Display plans to apply the world's first mass-produced "Oxide 1Hz" technology to OLED panels as well and is preparing for mass production in '27.
Separately, LG Display will continue to develop and apply energy-saving technologies such as "Oxide 1Hz," and will push ahead with a "carbon emission reduction project" to cut carbon emissions during the usage phase by up to 10%.
Jang Jae-won, head of mid-size product planning, said, "By successfully mass-producing the 'Oxide 1Hz' panel, which integrates the world's top-level technology, we will widen the technology gap with competitors and remake ourselves as a technology-centered company."
