LG Display has become the first company to mass-produce laptop displays capable of dynamically adjusting refresh rates from 1 to 120 hertz using oxide technology. The achievement marks a genuine efficiency milestone in portable computing, bringing power-saving tricks from smartphones to machines that users carry through their working days.
The new LCD panel can drop to 1 hertz when showing static content such as documents or e-books, before scaling up to as high as 120 Hz during video playback, gaming or other motion-heavy tasks. Refresh rates refer to how many times per second an image is redrawn on a display; higher rates improve smoothness, but maintaining them during static viewing wastes energy.
The practical benefit is substantial. According to LG Display, the panels can improve battery efficiency by 48 percent or greater by reducing unnecessary power consumption during idle screen states. That's not marginal; it's a meaningful extension of usable runtime for professionals who work unplugged.
How does this work? LG Display said this is the first time a panel can stably operate at an ultralow 1Hz and be mass-produced for laptops, enabled by oxide-based thin-film transistor technology that minimizes power leakage. The panel incorporates LG Display's proprietary algorithms, panel design and new materials to enable stable operation across the full 1-120 Hz range. In simpler terms, LG engineered the display to hold an electrical charge better during low-refresh-rate periods, eliminating the constant redrawing that drains battery life.
The technology is not entirely new to consumer electronics. Apple was the first to pioneer the technology in the Watch Series 5, with an LTPO display that could switch from 60 Hz to 1 Hz to save power; a few years later, smartphones began to incorporate this same technology, including the OnePlus 9 and Oppo Find X3 Pro. What makes LG's implementation significant is achieving this at scale in laptop panels, a far more complex engineering challenge given the larger screen size and production volume.
The display panels will be supplied to US PC maker Dell for use in its premium XPS laptops unveiled at CES 2026. Early reviews confirm the battery gains aren't theoretical. Gizmodo tested the battery life on both the XPS 14 with the LCD panel and the OLED screen and found the less pretty device was much better in battery life, with that extra longevity equaling several more hours doing browsing and typing work.
There are legitimate trade-offs. LCD panels can sport a quality picture and normally cost less than other screen alternatives, but OLED displays have much better contrast and offer far deeper blacks than any typical backlit liquid crystal display. So LG's Oxide 1Hz technology solves a power problem without solving the image-quality gap that keeps many consumers preferring OLED.
That gap is closing. LG also announced it will be debuting OLED counterparts of its 1 Hz-capable LCDs beginning in 2027. The panels could also gain traction as power consumption rises with the growing use of AI-driven computing tasks. If artificial intelligence truly drives laptop workloads higher, as many predict, efficient displays become essential rather than luxuries.
Intel and BOE are also working on new displays that achieve the same thing and are building their new displays with LTPO technology, suggesting this isn't a flash of LG's innovation but rather an industry direction. Competition will likely drive costs down and force manufacturers to adopt the standard.
For consumers shopping for a laptop, the Oxide 1Hz LCD option offers concrete value if you spend significant time on static tasks like email, research or document editing. The 48 percent efficiency gain is real, measurable, and meaningful for anyone working away from mains power. The trade-off is accepting LCD image quality in exchange for hours of extra runtime. In that equation, reasonable people will choose differently depending on their priorities. What matters is that the choice now exists.
